Background: Operative repair of ruptured abdominal aortic aneurysm (RAAA) is associated with a high mortality rate but reported figures vary widely. The aim of this study was to estimate the operative mortality of RAAA repair and determine how it has changed over time. Methods: A meta-analysis of all English language literature quoting figures for operative mortality of RAAA repair. Results: The pooled estimate for the overall operative mortality rate of RAAA repair from 1955 to 1998 was 48 (95 per cent confidence interval 46 to 50) per cent. Meta-regression analysis of operative mortality over time demonstrated a constant reduction of approximately 3·5 per cent per decade (1954–1997) with an operative mortality rate estimate for the year 2000 of 41 per cent. Seventy-seven studies reported intraoperative mortality but, while this appears to have remained constant over time, there was evidence of the presence of publication bias in the subgroup of papers reporting this outcome. There was no evidence of publication bias for the overall operative mortality outcome. Conclusion: Contrary to the conclusion of recent studies, this paper demonstrates a gradual reduction with time in the operative mortality rate of RAAA repair. [ABSTRACT FROM AUTHOR]

The objective of this systematic review is to compare operative and perioperative outcomes for MIS versus MS. Online databases Medline, EMBASE, Cochrane Library and Web of Science were searched from inception until July 2018. Both randomized and observational studies of patients undergoing aortic root, ascending aorta or aortic arch surgery by MIS versus MS were eligible for inclusion. Primary outcomes were 30-day mortality, reoperation for bleeding, perioperative renal impairment and neurological events. Intraoperative and postoperative timing measures were also evaluated. Thirteen observational studies were included comparing 1101 MIS and 1405 MS patients. The overall quality of evidence was very low for all outcomes. Mortality and the incidence of stroke were similar between the 2 cohorts. Meta-analysis demonstrated increased length of cardiopulmonary bypass (CPB) time for patients undergoing MS [standardized mean difference 0.36, 95% confidence interval (CI) 0.15–0.58; P  = 0.001]. Patients receiving MS spent more time in hospital (standardized mean difference 0.30, 95% CI 0.17–0.43; P  < 0.001) and intensive care (standardized mean difference 0.17, 95% CI 0.06–0.27; P  < 0.001). Reoperation for bleeding (risk ratio 1.51, 95% CI 1.06–2.17; P  = 0.024) and renal impairment (risk ratio 1.97, 95% CI 1.12–3.46; P  = 0.019) were also greater for MS patients. There was substantial heterogeneity in meta-analyses for CPB and aortic cross-clamp timing outcomes. MIS may be associated with improved early clinical outcomes compared to MS, but the quality of the evidence is very low. Randomized evidence is needed to confirm these findings.

OBJECTIVES Our study describes and analyses the results from aortopexy for the treatment of airway malacia in children. METHODS Demographic data, characteristics and preoperative, operative and outcome details, including the need for reintervention, were collected for children undergoing aortopexy between 2006 and 2016. RESULTS One hundred patients [median age 8.2 months, interquartile range (IQR) 3.3–26.0 months] underwent aortopexy. Sixty-four (64%) patients had tracheomalacia (TM) only, 24 (24%) patients had TM extending into their bronchus (tracheobronchomalacia) and 11 (11%) patients had bronchomalacia. Forty-one (41%) children had gastro-oesophageal reflux disease, of which 17 (41%) children underwent a Nissen fundoplication. Twenty-eight (28%) children underwent a tracheo-oesophageal fistula repair prior to aortopexy (median 5.7 months, IQR 2.9–17.6 months). The median duration of follow-up was 5.3 years (IQR 2.9–7.5 years). Thirty-five (35%) patients were on mechanical ventilatory support before aortopexy. Twenty-seven (77%) patients could be safely weaned from ventilator support during the same admission after aortopexy (median 2 days, IQR 0–3 days). Fourteen patients required reintervention. Overall mortality was 16%. Multivariable analysis revealed preoperative ventilation (P  = 0.004) and bronchial involvement (P  = 0.004) to be adverse predictors of survival. Only bronchial involvement was a predictor for reintervention (P  = 0.012). CONCLUSIONS Aortopexy appears to be an effective procedure in the treatment of children with severe airway malacia. Bronchial involvement is associated with adverse outcome, and other procedures could be more suitable. For the treatment of severe airway malacia with isolated airway compression, we currently recommend aortopexy to be considered. [ABSTRACT FROM AUTHOR]

OBJECTIVES: In this study, a propensity-matching analysis was used to compare biological versus mechanical composite valve graft implantation for early mortality and morbidities and for late complications including the need for aortic reintervention. METHODS: Between 1978 and 2011, 1112 consecutive patients underwent a complete aortic root replacement using either a biological Bentall (BB, n = 356) or a mechanical Bentall (MB, n = 756) valve conduit. Preoperative data were stratified according to the type of valve graft, and treatment bias was addressed by propensity score analysis. RESULTS: Two homogeneous groups of 138 patients were obtained. Hospital mortality between them was comparable (MB = 7.2% and BB = 5.8%, P = 0.6). They also had similar results after a mean follow-up time of 40 ± 38 months. Propensity-adjusted Cox-regression analysis showed no relationship between the type of prosthesis and all-cause mortality at follow-up (hazards ratio: 0.88; 95% confidence interval: 0.50--2.14; P = 0.4). Freedom from proximal aortic reintervention at 1, 5 and 7 years was 99.1 ± 0.9% in the MB group compared with 98.4 ± 1.1%, 93.0 ± 3.2% and 93.0 ± 3.2% in the BB group (long-rank P = 0.07). CONCLUSIONS: The Bentall procedure is a safe and reproducible treatment for ascending aorta pathologies. The choice of either a mechanical or a biological valve graft seems to have no influence on early and late midterm adverse outcomes including need for aortic reinterventions. [ABSTRACT FROM AUTHOR]

OBJECTIVES: The aim was to evaluate the impact of the aortic valve reimplantation (David) and of the aortic root (AoR) remodelling (Yacoub) on the AoR haemodynamics. METHODS: In an experimental setup where the clinical scenario of Yacoub, (n=5, domestic pig) and of David (n=5, domestic pig) procedure was performed in each AoR, six high-fidelity (200 Hz) sonomicrometric crystals were implanted. Crystals were positioned at three commissures with their projection at the root base. In post-measurement processing 3D deformation of both AoR was determined and used for computed fluid dynamic modelling in order to evaluate pressure, velocity and shear stress profiles. RESULTS: In David AoR: high pressure (> 150 mmHg) and low to moderate shear stress (0-30 Pa) were found from the period of isovolemic contraction to the closure of the aortic valve. At mid diastole pressure augmentation (> 120 mmHg) a low shear stress (0-10 Pa) was registered at the leaflets, three commissures, and intervalvular triangles. In Yacoub AoR: high pressure (110-130 mmHg) with moderate low shear stress (0-30 Pa) was only registered at isovolemic contraction. CONCLUSION: The results show that haemodynamic conditions following a David procedure have a less favourable pattern as compared to a Yacoub AoR. In David AoR, high pressure and low shear stress are present during 2/3 of the cardiac cycle, whereas in Yacoub root, these conditions are present only for a short period of isovolemic contraction.

OBJECTIVES: Giant cell arteritis (GCA) may affect mid-size and large-size arteries. Although temporal arteritis is a well-characterized clinical entity, GCA of the thoracic aorta remains ill defined. The aim of the study was to evaluate the clinical presentation, surgical and mid-term outcomes in patients operated for GCA of the thoracic aorta. METHODS: A retrospective review of patients operated for GCA of the thoracic aorta was conducted. The diagnosis of GCA was established by the pathology report. RESULTS: Forty consecutive patients (mean age of 66.6 ± 9.1 years) with a diagnosis of GCA of the thoracic aorta were operated on. A history of polymyalgia rheumatica or temporal arteritis was positive in 22.5% of patients. Emergency surgery was performed in 10% of patients (3 'type A' dissections and 1 'type B'). Mega-aorta syndrome was present in 10% of patients. Involvement of the ascending aorta was present in 100% of patients. One patient had a previous branched thoracic endovascular replacement (TEVAR) with a type I proximal endoleak. In 4 patients, the thoracic aorta was totally replaced. Eighty-five percent of patients had an arch replacement; 79.4% a hemiarch and 20.6% a full arch. The mean circulatory arrest time was 16.3 ± 12.3 min. Eighty percent of patients had an aortic valve procedure; aortic valve replacement was performed in 50% of them and Bentall-De Bono/valve sparing in 50%. Cerebrovascular accident occurred in 2.5% of patients. No patient died during hospitalization. The mean hospital stay was 8.7 ± 3.0 days. The mean postoperative follow-up time was 4.2 ± 2.3 years, with a mean of 4.2 ± 2.2 thoraco-abdominal computed tomographies (CTs)/patient. Four patients had late reinterventions: 2 were valve-related, 1 for a distal type I endoleak treated with a distal TEVAR extension and 1 type II open thoraco-abdominal replacement for disease progression. One distal type I TEVAR endoleak was treated medically. Aortic diameter progressions on CT (mm/year) were 0.7 ± 1.0 mm for the arch, 1.2 ± 2.0 mm for the isthmus, 1.1 ± 1.7 mm for the mid-descending, 0.7 ± 0.9 mm for the aortic hiatus, 0.5 ± 0.5 mm for the supra-renal aorta and 0.6 ± 0.6 mm for the infra-renal aorta. One patient who declined reoperation on the descending aorta died suddenly 3 years after her initial operation. The 5-year overall survival rate was 91%. CONCLUSIONS: GCA of the thoracic aorta may be suspected in less than 25% of patients preoperatively. Clinical presentation may be acute or chronic with localized or diffused aortic involvement but always involved the ascending aorta. Surgery may be performed with excellent outcomes. Follow-up imaging is mandatory to assess aortic progression. [ABSTRACT FROM AUTHOR]

OBJECTIVES: The optimal surgical strategy for acute type A aortic dissection (ATAAD) is still controversial because of the inconsistent or even conflicting results of proximal aortic repair (PR) versus extensive aortic repair (ER) on early and late prognostic outcomes. This metaanalysis pooled data from all available studies of PR versus ER to get a summarized conclusion. METHODS: Studies were identified by searching the Medline, EMBASE and Cochrane databases. Early and late prognostic outcomes of interest were evaluated with meta-analysis. Fixed- or random-effect models were used according to the significance of heterogeneity. Robustness of pooled estimates and the source of heterogeneity were assessed via sensitivity analyses and meta-regression, respectively. Publication bias was evaluated by the funnel plot and Egger's test. RESULTS: Nine studies with a total of 1872 patients were included for the meta-analysis. Pooled results indicated that, when compared with the ER procedure, PR was associated with lower early mortality [risk ratio (RR) = 0.69, 95% confidence interval (CI) 0.54-0.90, P = 0.005] but higher incidence of postoperative aortic events including reoperation of the distal aorta (RR = 3.14, 95% CI 1.74-5.67, P < 0.001). PR and ER demonstrated analogous prognosis on long-term mortality (HR = 1.02, 95% CI 0.51-2.06, P = 0.96) and the incidences of early postoperative renal failure (RR = 0.75, 95% CI 0.49-1.14, P = 0.17) and stroke (RR = 0.73, 95% CI 0.30-1.78, P = 0.50). All the pooled results were robust to sensitivity analysis. Heterogeneity was insignificant except for the meta-analysis of late mortality. CONCLUSIONS: Performing a less aggressive initial surgical procedure of PR in ATAAD patients would have lower early mortality but elevated incidence rates of late aortic reintervention, when compared with ER. Other prognostic results of the two surgical strategies including long-term mortality were similar for both. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Recent studies have shown that aortic diameter alone is an insufficient parameter to identify patients at risk for aortic dissection. The aim of this study was to determine the value of the ratio of aortic diameter to medial wall thickness as a new marker of risk. METHODS: We obtained data from 181 patients with an ascending aortic aneurysm (n = 94) or an acute type A aortic dissection (n = 87), surgically treated at our institution (1996-2012). Measurements of the maximum aortic diameter and the medial wall thickness were conducted by retrospective review of preoperative imaging studies and histological specimens, respectively. RESULTS: Nearly 60% of the dissection patients had aortic diameters smaller than 50 mm. There was a significant negative linear correlation between medial wall thickness and aortic diameter (P = 0.01) in the dissection group only. Among patients with aortic diameters above 50 mm, dissection patients had significantly thinner aortic media (P = 0.04). Among patients with a mildly dilated aorta (>45 mm), the aortic diameter to medial wall thickness ratio was significantly higher in the dissection group (P = 0.04). CONCLUSIONS: Among patients with a dilatation of the ascending aorta of more than 45 and 49 mm, patients experiencing aortic dissection have a significantly higher aortic diameter to wall thickness ratio and a thinner aortic media, respectively. In the subset of patients with mild aortic dilatation, wall thickness might in the future serve as an additional parameter to help identify those patients who would benefit from prophylactic aortic surgery.

OBJECTIVES: To evaluate the early and long-term outcomes in patients undergoing complex aortic root reconstructions for complicated aortic root abscesses. METHODS: A total of 1199 patients underwent aortic valve surgery for aortic valve endocarditis between July 1999 and June 2012. Of these, 150 patients, who underwent complex isolated aortic root operations for aortic root abscesses, were included in this study. Radical resection of the abscess was performed in all patients followed by an aortic root replacement (ARR) in 91 (61.7%) or an aortic valve replacement with patch reconstruction of the aortic root in 59 (39.3%) patients. Prosthetic valve endocarditis was observed in 74 patients (49.3%). Logistic regression analysis identified the predictors of 30-day mortality. Estimated mean follow-up was 7.0 ± 0.5 years (range 0–12.6 years). RESULTS: Mean age was 62 ± 15 years and 87% (n = 130) were male. The majority of patients (91%; n = 137) underwent urgent or emergent surgery. Overall 30-day mortality was 19% (n = 29; ARR 21%; AVR 17%; P = 0.4). Postoperative low cardiac output, stroke and dialysis developed in 10.7, 4.7 and 25.3% of patients, respectively. Sepsis was the only independent predictor of 30-day mortality (odds ratio: 2.8; 95% confidence interval: 1.1–7.3; P = 0.03). The 1-, 5- and 10-year survival was 66 ± 5, 54 ± 5 and 51 ± 6%, respectively. Overall, 9% of surviving patients required a reoperation for recurrent endocarditis resulting in a 1-, 5- and 10-year freedom from reoperation of 93 ± 2, 91 ± 3 and 85 ± 5%, respectively, which was not influenced by surgical technique used (ARR vs AVR with patch reconstruction; log rank P = 0.9). CONCLUSIONS: The surgical treatment of aortic root abscess is a challenging operation and is associated with a high early morbidity and mortality. However, the long-term survival and freedom from reoperation is satisfactory. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Multiple arterial coronary artery grafting (MABG) improves long-term survival compared with single arterial CABG (SABG), yet the best second arterial conduit to be used with the left internal thoracic artery (LITA) remains undefined. Outcomes in patients grafted with radial artery (RA-MABG) versus right internal thoracic artery (RITA-MABG) as the second arterial graft were compared with SABG. METHODS: Multi-institutional, retrospective analysis of non-emergent isolated LITA to left anterior descending coronary artery CABG patients was performed using institutional Society of Thoracic Surgeon National Adult Cardiac Surgery Databases. 4484 (54.5%) SABG [LITA ± saphenous vein grafts (SVG)], 3095 (37.6%) RA-MABG (RA ± SVG) and 641 (7.9%) RITA-MABG (RITA ± SVG) patients were included. The RITA was used as a free (68%) or in situ (32%) graft. RA grafts were principally anastomosed to the ascending aorta. Long-term survival was ascertained from US Social Security Death Index and institutional follow-up. Triplet propensity matching and covariate- adjusted multivariate logistic regression were used to adjust for baseline differences between study cohorts. RESULTS: Compared with the SABG cohort, the RITA-MABG cohort was younger (58.6 ± 10.2 vs 65.9 ± 10.4, P < 0.001), had a higher prevalence of males (87% vs 65%, P < 0.001) and was generally healthier (MI: 36.7% vs 56.7%, P < 0.001, smoking: 56.8% vs 61.1%, IDDM: 3.0% vs 14.4%, CVA: 2.6% vs 10.0%). The RA-MABG cohort was generally characterized by a risk profile intermediate to that of SABG and RITA-MABG. Unadjusted 5-, 10- and 15-year survival rates were best in RITA-MABG (95.2%, 89% and 82%), intermediate in RA-MABG (89%, 74%, 57%) and worst in SABG (82%, 61% and 44%) cohorts (all P < 0.001). Propensity matching yielded 551 RA-MABG, RITA-MABG and SABG triplets, which showed similar 30-day mortality. Late survival (16 years) was equivalent in the RA-MABG and RITA-MABG cohorts [68.2% vs 66.7%, P = 0.127, hazard ratio (HR) = 1.28 (0.96-1.71)] and both significantly better than SABG (61.1%). The corresponding SABG versus RITA-MABG and SABG versus RA-MABG HRs (95% confidence interval) were 1.52 (1.18-1.96) and 1.31 (1.01-1.69) with P < 0.002 and P = 0.038, respectively. CONCLUSIONS: RA-MABG or RITA-MABG equally improve long-term survival compared with SABG and thus should be embraced by the Heart Team as the therapy of choice in LITA-based coronary artery bypass surgery.

In 2008, a 26-year old man had personalized external aortic root support (PEARS) with a macroporous mesh. He was the 16th of 46 patients to have this operation. He had a typical Marfan habitus. His mother died of this disease as did his brother, with an aortic dissection. The patient himself died suddenly 4.5 years after his PEARS operation. At autopsy, there was no blood in the pericardium. The coronary orifices and proximal arteries were normal. His bicuspid aortic valve was minimally regurgitant as it was prior to operation and remained throughout follow-up. Macroscopically the implanted mesh was embedded in the adventitia and not separable from the aortic wall. Microscopically it was fully incorporated with collagen fibres as has been seen in our animal studies. The unsupported aortic arch showed some focal fragmentation of elastic fibres and a mild increase in mucopolysaccharides consistent with Marfan syndrome. These appearances were not present in the supported aortic root, which had the histological appearance of a normal aorta. He was the first patient to die with an implant. The histological appearances suggest the possibility that the incorporated support of the aortic root allowed recovery of the microstructure of the media. [ABSTRACT FROM AUTHOR]

OBJECTIVES: The study was conducted to evaluate our results of acute aortic dissection repair taking into account the impact of surgical experience in aortic surgery. METHODS: Between August 2002 and March 2013, 162 consecutive patients (mean age: 63 ± 14 years) underwent surgery for acute type A aortic dissection. All patients were operated on by one of the clinic's attending surgeons with wide experience in cardiac surgery (at least 2000 procedures performed personally), however about one-half of the patients (75 patients, 46%) were operated by the aortic team (AT) surgeons with profound experience in complex aortic pathologies. All perioperative data were collected prospectively and retrospective statistical analysis was performed using uni- and multivariate analyses to identify predictors for surgical adverse outcome (AO) containing in-hospital and/or 90-day mortality and new permanent neurological and organ dysfunctions. RESULTS: AO was observed in 36 patients (22.2%) including in-hospital mortality in 22 (13.6%). Multivariate logistic regression analysis identified surgery not performed by the AT as the strongest predictor for AO (odds ratio: 14.1; 95% confidence interval: 3.5-55.6; P < 0.0001) followed by any malperfusion, myocardial infarction and creatinine level. Two groups were built according to the surgery performed by the AT (Group AT) or by the surgeons not on the AT (Group No-AT). The comparison of the groups showed no relevant differences regarding the preoperative characteristics, especially compromised consciousness, malperfusion and extent of dissection. Yet, the outcomes in Group AT vs No-AT were significantly different presenting AO: 8.0 vs 34.5% (P < 0.0001), in-hospital mortality: 4.0 vs and 21.8% (P < 0.001), new permanent neurological deficit: 2.7 vs 11.5% (P = 0.03), even if valve-sparing repairs and complete arch replacements were much more frequent in Group AT. The groups also differed considerably in regard to cannulation and perfusion management, which might play a decisive role in surgical outcome. CONCLUSIONS: Aortic repair in acute type A dissection, when performed by highly specialized aortic surgeons, offers not only much better outcomes but also provides significantly higher rate of curative albeit valve-sparing aortic repairs. Patient-centred care in referral aortic centres with surgery performed by specialized teams should be striven for to improve surgical results in acute aortic dissection surgery.

OBJECTIVES: Aortic dissection DeBakey type I and II may require distal reinterventions after initial proximal repair. We evaluated outcomes following open versus endovascular approaches to distal aortic pathologies after surgery for acute dissection. METHODS: One hundred and forty-one consecutive patients underwent 152 distal reinterventions after previous type I or II dissection repair [63 (first quartile, 55; third quartile, 72) years old; initially 86% DeBakey type I; 54% hemiarch, 39% isolated ascending, 7% total arch replacement] at two tertiary centres in the USA and Europe over the last 14 years. Among them, 56 and 85 required reintervention for the aortic arch and the descending aorta, respectively. The median follow-up was 2.1 (first quartile, 0.8; third quartile, 5.8) years (439 patientyears). RESULTS: The median time between acute aortic dissection repair and descending aortic reintervention was longer in the open group (2.7 (first quartile, 0.8; third quartile, 6.7) vs 0.6 (first quartile, 0.1; third quartile, 3.5) years, P < 0.01). There was one irreversible spinal ischaemia in the open and one stroke in the endovascular group. Two patients in the open and none in the endovascular group required re-exploration for bleeding. Two open and 4 endovascular patients required more than 1 distal reintervention (6 vs 8%, P = 1). Descending aortic open-repair patients experienced higher in-hospital mortality (23 vs 0%, P < 0.01) and lower survival at 1 and 5 years (74 ± 8% vs 96 ± 3%, 65 ± 9% vs 92 ± 5%, P < 0.01, respectively). CONCLUSIONS: Endovascular intervention for descending aortic pathologies after DeBakey type I or II dissection surgical repair is associated with lower in-hospital mortality and better survival, and does not raise the likelihood of later reinterventions at the mid-term follow-up.

OBJECTIVES To evaluate our results of valve-sparing aortic root replacement and associated (multiple) valve repair. METHODS From September 2003 to September 2013, 97 patients had valve-sparing aortic root replacement procedures. Patient records and preoperative, postoperative and recent echocardiograms were reviewed. Median age was 40.3 (range: 13.4–68.6) years and 67 (69.1%) were male. Seven (7.2%) patients were younger than 18 years, the youngest being 13.4 years. Fifty-four (55.7%) had Marfan syndrome, 2 (2.1%) other fibrous tissue diseases, 15 (15.5%) bicuspid aortic valve and 3 (3.1%) had earlier Fallot repair. The reimplantation technique was used in all, with a straight vascular prosthesis in 11 (26–34 mm) and the Valsalva prosthesis in 86 (26–32 mm). Concomitant aortic valve repair was performed in 43 (44.3%), mitral valve repair in 10 (10.3%), tricuspid valve repair in 5 (5.2%) and aortic arch replacement in 3 (3.1%). RESULTS Mean follow-up was 4.2 ± 2.4 years. Follow-up was complete in all. One 14-year old patient died 1.3 years post-surgery presumably of ventricular arrhythmia. One patient underwent reoperation for aneurysm of the proximal right coronary artery after 4.9 years and 4 patients required aortic valve replacement, 3 of which because of endocarditis after 0.1, 0.8 and 1.3 years and 1 because of cusp prolapse after 3.8 years. No thrombo-embolic complications occurred. Mortality, root reoperation and aortic regurgitation were absent in 88.0 ± 0.5% at 5-year follow-up. CONCLUSIONS Results of valve-sparing root replacement are good, even in association with a high incidence of concomitant valve repair. Valve-sparing aortic root replacement can be performed at a very young age as long as an adult size prosthesis can be implanted. [ABSTRACT FROM AUTHOR]

OBJECTIVES Several techniques have been described for the treatment of thoraco-abdominal aneurysms in patients with mega-aortic syndrome (MAS), but the incidence of stroke, spinal cord injury and endoleaks remains significant. We present the mid-term results of a new hybrid, multistep technique to treat patients with MAS. METHODS From November 2005 to November 2012, 118 patients with MAS underwent surgical repair of thoracic and thoraco-abdominal aneurysms with the Lupiae technique. Fifty-five patients presented chronic aneurysms and 63 patients Type A acute dissections. Eighty-three patients underwent ascending aorta and arch replacement with a multibranched Dacron graft and epiaortic vessels rerouting (thoracic Lupiae procedure). Twenty patients had the thoracic Lupiae procedure plus partial visceral debranching (coeliac trunk and superior mesenteric artery [SMA]) through an upper mini-laparotomy. Fifteen patients had the thoracic Lupiae procedure plus a complete visceral debranching (coeliac trunk, SMA and renal arteries) using a second multibranched Dacron graft to replace the infrarenal aorta. All the patients with chronic aneurysms and 34 of 63 patients with Type A dissections underwent implant of endovascular stent grafts. RESULTS In-hospital mortality was 8.4%. No patients had stroke or spinal cord injury. The incidence of temporary renal failure was 5.2%. No patients presented endoleaks immediately and at follow-up CT scans. No death or reoperation occurred during the follow-up. CONCLUSIONS These results evidence that the Lupiae technique is a safe and effective option for the treatment of patients with MAS, achieving the complete exclusion of thoraco-abdominal aneurysms and of the residual false lumen in patients with acute aortic dissections.

OBJECTIVES The purpose of this study was to evaluate the clinical outcomes of emergency surgery for acute type B aortic dissection with rupture and to compare results between open surgery and thoracic endovascular aortic repair (TEVAR). METHODS Two hundred and ninety-four patients with acute type B aortic dissection were admitted to our hospital between January 2000 and March 2012. At presentation, 30 (10%) patients had rupture (20 men, 10 women; mean age, 71 ± 15 years), among whom 23 underwent emergency surgery: 9 underwent TEVAR and 14 underwent open surgery. The objective of TEVAR was closure of the primary entry site and the secondary tear site in the descending thoracic aorta. RESULTS In the TEVAR group, technical success was achieved: the primary entry site was closed, and bleeding was controlled in all 9 patients. There was no operative death, and 1 (13%) patient had cerebral infarction. In the open surgery group, 2 (14%) patients died during hospitalization, and 4 (29%) had cerebral infarction in the acute phase. Hospitalization tended to be longer in the open surgery group than in the TEVAR group. The overall survival rate at 1 year was 71 ± 17% in the TEVAR group and 86 ± 9% in the open surgery group (P = 0.89). CONCLUSIONS TEVAR for acute type B aortic dissection with rupture could be performed with relatively low morbidity and mortality, with no significant difference when compared with open surgery. The main objective of TEVAR for acute type B aortic dissection with rupture is control of bleeding, which can be achieved by closing the primary entry site and the secondary tear site in the descending thoracic aorta. If anatomically feasible and performed immediately, TEVAR is the treatment of choice for acute type B aortic dissection with rupture because it is less invasive than open surgery.

OBJECTIVES Conflicting results have been reported on late aortic growth and complication rates of the descending thoracic aorta in patients with Marfan syndrome (MFS) after proximal aortic surgery. METHODS Of 198 Marfan patients followed up regularly, 121 (43% David-I, 7% David-II, 11% supracoronary replacement, 52% mechanical conduit, 8% arch replacement) were analysed after proximal aortic surgery retrospectively. 97% had MFS1, 3% MFS2 (Loeys-Dietz-Syndrome); 56% were male and the mean age was 35 ± 13 years. 65% were initially operated on for root/ascending aortic aneurysm and 35% for aortic dissections. Using automated computed tomography angiography and magnetic resonance angiography cross-sectional analyses, the mean diameters of the distal arch, mid-descending and distal supradiaphragmatic descending thoracic aorta were measured at early and late follow-up (mean 6.3 years for aneurysms and 4.7 years for dissections). The mean duration of clinical follow-up was 7.6 years and the cumulative clinical follow-up comprised 894 patient-years. RESULTS At 20 years, overall freedom from distal aortic complications and/or reintervention was 76% (51–86%) for aneurysms and 52% (28–71%) for dissections (P = 0.03). In non-dissected aortas, distal aortic growth was significant, but minimal: arches grew from 25.2 ± 0.6 to 26.3 ± 0.8 mm (P = 0.01), mid-descending aortas from 22.2 ± 0.5 to 24.9 ± 1.2 mm (P = 0.05) and distal descending aortas from 22.1 ± 0.7 to 24.2 ± 1.4 (P = 0.02, 0.58 mm/year ± 0.5 mm). Dissected distal aortas increased by a mean of 0.3 ± 0.5 mm/year. Dissection (P < 0.001), urgent procedure (P = 0.02) and hypertension (0.052) were associated with larger distal aortic diameters at late follow-up and more significant aortic growth over time. CONCLUSIONS Late distal complication rates are low for patients initially presenting with aneurysms. The risk of late distal reoperation is dictated by the initial pathology and by the presence of an initial dissection and not by faster distal aortic growth. Strategies to completely restore a non-dissected anatomy might improve late surgical outcome in Marfan's syndrome. [ABSTRACT FROM PUBLISHER]

OBJECTIVES To investigate mid-term outcome in patients undergoing thoracic endovascular aortic repair (TEVAR) for non-dissected aortic pathology with favourable and unfavourable landing zone and aortic anatomy. METHODS Between 2000 and 2011, TEVAR was performed in 208 patients with descending thoracic aortic disease. Of 105 patients with non-dissected thoracic aortic pathology, 69 presented with unfavourable anatomy as defined by short length (<15 mm), large diameter (>42 mm), angulation of >60° of the proximal or distal landing zone or extreme aortic tortuosity. The endpoints perioperative mortality, 1-year survival, endoleak occurrence and incidence of secondary intervention were compared with the remaining 36 patients with favourable anatomy. RESULTS Median follow-up was 18 months. TEVAR was performed emergently in 24 of 69 (35%) patients with unfavourable anatomy and in 11 of 36 (31%) of those with favourable anatomy (P = 0.68). No patients underwent conversion to open surgery, no periinterventional rupture was observed. Perioperative mortality did not differ between cohorts (1/69 vs 1/36, P = 0.78). Postoperative permanent spinal cord ischaemia occurred in patients with unfavourable anatomy only (2/69 vs 0/36, P = 0.78). Early endoleak and secondary intervention were more frequent in patients with unfavourable anatomy (19/69 vs 7/36 and 13/69 vs 1/36), but not statistically significant (P = 0.5 and P = 0.13, respectively). One-year aorta-related survival rates were similar in both groups (66/69 vs 33/36, P = 0.45). CONCLUSIONS Mid-term outcome after TEVAR does not differ between patients with favourable and unfavourable landing zone anatomy in terms of aorta-related survival. However, the more frequent need for secondary intervention warrants a more rigorous follow-up after TEVAR in patients with unfavourable anatomy. [ABSTRACT FROM PUBLISHER]

At least every ten years, each specialty should reflect upon its past, its present and its future, in order to be able to reconfirm the direction in which it is headed, to adopt suggestions from inside and outside and, consequently, to improve. As such, the aim of this manuscript is to provide the interested reader with an overview of how aortic surgery and (perhaps more accurately) aortic medicine has evolved in Europe, and its present standing; also to provide a glimpse into the future, trying to disseminate the thoughts of a group of people actively involved in the development of aortic medicine in Europe, namely the Vascular Domain of the European Association of Cardio-Thoracic Surgery (EACTS).

BACKGROUND Through oocyte donation (OD), women with Turner syndrome (TS) may achieve motherhood. However, this population has a high prevalence of cardiac malformations and carry a risk for aortic dissection that is increased by pregnancy. Until recently, the necessity for a specialized cardiac evaluation before pregnancy was underestimated as was the need for follow-up through adulthood. The aim of this study was to evaluate the follow-up (mainly cardiovascular) of women with TS requesting OD. METHODS Disease monitoring since diagnosis and prior cardiac evaluations conducted out of our centre were assessed in 25 women with TS who requested OD. New cardiac evaluations using echocardiography and magnetic resonance imaging were performed by our specialized cardiologist in 18 of these patients. RESULTS We observed that the medical follow-up of women with TS was often deficient throughout adulthood. Most of the prior cardiac evaluations performed by cardiologists not accustomed to women with TS, either before (n= 8) or when starting OD (n= 12), were considered normal. However, when revaluated by a cardiologist who is familiar with TS, seven women were diagnosed with a bicuspid aortic valve and thus excluded from OD. In addition, when appropriate screening was conducted by our referent cardiologist before OD no cardiac complication was observed during pregnancy or delivery. CONCLUSIONS Careful follow-up, including cardiac evaluation, should be recommended for women diagnosed with TS, before and after puberty. Moreover, assessment of cardiovascular parameters by a cardiologist familiar with TS should be routinely repeated before undertaking OD. [ABSTRACT FROM PUBLISHER]

The article presents a study which identifies the co-morbidity among surgical patients using Royal College of Surgeons (RCS) Charlson Score. The study involves the development of RCS Charlson Score by coding philosophy and validation of English Hospital Episode Statistics score data for abdominal aortic aneurysm (AAA) repair, replacements of aortic valve, hip, and resection of transurethral prostate. It concludes that RCS Charlson Score identifies co-morbidity in surgical patients in England.

The article presents a study on the treatment of type IV thoracoabdominal aortic aneurysm (TAAA) by means of a surgical approach with supracoeliac clamping of the aorta. It notes that abdominal approach to TAAA has minimized damage to the diaphragm and that it allowed extubation. Postoperative complications such as myocardial infarction, atelectasis and oliguria were noted. It concludes that abdominal approach for TAAA can be initiated with acceptable levels of morbidity and mortality.

The article discusses a meta-analysis to compare operative outcomes, postoperative complications, 30-day mortality and long-term patient survival after an abdominal aortic aneurysm (AAA) surgery, using open and endovascular approaches. Results reveal that the endovascular repair of AAA offers a benefit in terms of reduction in postoperative adverse events and a 30-day mortality. In the longer term, it is tied with a reduction in aneurysm-related mortality, but not in all-cause mortality.

The article discusses the results of a study on the cost-effectiveness of endovascular abdominal aortic aneurysm repair (EVAR). It reveals that older patients should benefit more from EVAR in terms of absolute risk reduction, however, EVAR will be cost-effective in this group only if patients maintain such early survival advantage over open surgery.

Background: Differences between women and men in treatment and outcome after admission with a ruptured abdominal aortic aneurysm (AAA) in England were studied. Methods: Routinely collected data in Hospital Episode Statistics, linked to death records, for emergency admissions for ruptured AAA in England were analysed. The percentage of patients who underwent surgical repair was calculated, together with 30-day case fatality rates and age-adjusted odds ratios (ORs), comparing women with men. Results: A total of 2463 women and 7615 men were admitted with a primary diagnosis of ruptured AAA (mean age 79.8 and 74.9 years respectively); 39.6 per cent of women and 66.4 per cent of men underwent surgical repair (OR 0.47 (95 per cent confidence interval 0.42 to 0.52)). Overall, 75.6 per cent of women and 61.7 per cent of men died within 30 days of admission (OR 1.36 (1.22 to 1.52)). The death rate for women and men who had surgery was similar (OR 1.01 (0.88 to 1.17)); when no operation was performed the mortality rate was higher in women, but not significantly so (OR 1.14 (0.91 to 1.42)). Conclusion: Women with a ruptured AAA were less likely to be treated surgically than men, and their overall mortality rate was higher. Lower rates of surgery in women than in men may contribute to the higher mortality in women, but other explanations are possible. [ABSTRACT FROM AUTHOR]

Background: Cardiopulmonary exercise (CPX) testing measures how efficiently subjects meet increased metabolic demand. This study aimed to determine whether preoperative CPX testing predicted postoperative survival following elective abdominal aortic aneurysm (AAA) repair. Methods: Some 130 patients had CPX testing before elective open AAA repair. Additional preoperative, operative and postoperative variables were recorded prospectively. Median follow-up was 35 months. The correlation of variables with survival was assessed by single and multiple regression analyses. Results: CPX testing identified 30 of 130 patients who had been unfit before surgery. Two years after surgery the Kaplan-Meier survival estimate was 55 per cent for the 30 unfit patients, compared with 97 per cent for the 100 fit patients. The absolute difference in survival between these two groups at 2 years was 42 (95 per cent confidence interval 18 to 65) per cent (P < 0.001). Conclusion: Preoperative CPX testing, combined with simple co-morbidity scoring, identified patients unlikely to survive in the mid-term, even after successful AAA repair. [ABSTRACT FROM AUTHOR]

Background: This study aimed to explore the value of the Glasgow Aneurysm Score in predicting the immediate and long-term outcome after elective open repair of abdominal aortic aneurysm (AAA). Methods: Some 403 patients underwent elective open repair of an infrarenal AAA and were classified retrospectively according to the criteria of the Glasgow Aneurysm Score (risk score = (age in years) + (7 for myocardial disease) + (10 for cerebrovascular disease) + (14 for renal disease)). Results: Fourteen patients (3·5 per cent) died after operation, 23 (5·7 per cent) had a myocardial infarction and six (1·5 per cent) had a stroke. One hundred and nine patients (27·0 per cent) experienced severe postoperative complications. The Glasgow Aneurysm Score was predictive of postoperative death (area under the receiver-operator characteristic curve (AUC) 0·80, 95 per cent confidence interval (c.i.) 0·71 to 0·90), severe postoperative complications (AUC 0·67, 95 per cent c.i. 0·61 to 0·73), myocardial infarction (AUC 0·72, 95 per cent c.i. 0·62 to 0·82), myocardial infarction-related postoperative death (AUC 0·78, 95 per cent c.i. 0·63 to 0·94) and stroke (AUC 0·84, 95 per cent c.i. 0·74 to 0·95). Univariate analysis showed that this risk index was also predictive of long-term survival Conclusion: The Glasgow Aneurysm Score is a good predictor of outcome after elective open repair of AAA. Its simplicity and accuracy make it useful for preoperative risk stratification. [ABSTRACT FROM AUTHOR]

Background: Hospital episode statistics (HES) regarding death after aortic surgery were analysed to evaluate their potential value as a performance indicator. Methods: HES data for all acute hospitals in England and Wales from 1996 to 2001 were analysed retrospectively. In-hospital mortality was calculated for all patients over 40 years of age who underwent abdominal aortic procedures or died in hospital with a primary diagnosis of aortic aneurysm. Results: Some 38 319 cases were identified, of which 8·9 per cent were complex, 46·8 per cent were elective and 44·4 per cent were emergencies. The elective mortality rate was 6·4 per cent overall; that after emergency operation was 35·0 per cent, rising to 41·6 per cent if urgent procedures were excluded and 63·1 per cent if unoperated cases were included. Over the 5-year interval a median of 68 (interquartile range 30-108) elective procedures were carried out by individual hospitals. Considerable variation was identified in the proportion of elderly patients, tertiary referrals and the proportion of emergency admissions that had surgery. Conclusion: The use of mortality data may be misleading owing to identifiable differences in case mix and selection. Some redefinition of groups may help to provide more valid data, but ultimately only high-quality data with clinical information are likely to allow meaningful comparisons of performance.

Background: Perioperative myocardial infarction may not be diagnosed correctly because World Health Organization criteria are often not met and creatinine kinase myocardial fraction (creatinine kinase/creatinine kinase MB isoenzyme; CK/CK-MB) ratios can be difficult to interpret. Cardiac troponin (cTn) I and cTnT are the most sensitive and specific markers of myocardial cell necrosis currently available but are not widely used in surgical practice. The aim was to compare cTnI and CK/CK-MB ratios in the detection of myocardial injury following aortic surgery. Methods: This was a prospective study of 59 patients undergoing elective (n = 28) or ruptured (n = 24) abdominal aortic aneurysm repair or elective aortofemoral bypass (n = 7). cTnI level was measured before operation and at 6, 24 and 48 h after surgery. The CK/CK-MB ratio was measured where cTnI was detectable. Results: Some 14 of 24 emergency and ten of 35 elective patients had detectable cTnI (greater than 0·5 ng/ml) at one or more time-points. The CK/CK-MB ratio was greater than 5 per cent in only four of 24 patients having an emergency operation and in none of the elective patients with detectable cTnI. Conclusion: Over half of patients undergoing emergency operation and more than a quarter of those having elective aortic surgery suffered myocardial necrosis as determined by detectable cTnI levels. This was accompanied by a raised CK/CK-MB ratio in less than one-fifth of patients. [ABSTRACT FROM AUTHOR]

Background: There is increasing pressure to monitor surgical performance. In the UK, the Department of Health has produced clinical indicators based on routine data to monitor performance. This study analysed whether such data could measure performance in aortic surgery. Methods: Routine hospital data on postoperative mortality were collected for 1995–1997 in the Trent region. Procedural and diagnostic codes, modes of admission, districts of residence, treatment and specialty data were compared with audit data and the Operating Theatre Information System. Results: Inaccuracies in the Health Resource Group (HRG) codes meant that 21·4 per cent of elective aortic cases (HRG Q02) were probably emergencies and 26 per cent of probable ruptured aneurysms were not coded as a vascular emergency. Case mix and patient selection introduced a bias, apparent between tertiary and district general hospitals. For patients aged over 80 years, two district hospitals undertook no elective aortic surgery; the rate for emergency aortic surgery varied between 16 and 25 per cent in the district hospitals, and was 77 per cent in the tertiary centre. Conclusion: Crude mortality rates used as an indicator of performance are subject to bias and distortion owing to the collection of incorrect information, variation in patient selection between hospitals and case-mix differences. There was a considerable variation in selection and outcomes of patients undergoing aortic surgery in this study. [ABSTRACT FROM AUTHOR]

We report a case of a Marfan syndrome patient who developed a complicated clinical course after total aortic repair using a hybrid technique. After hybrid total aortic repair, this patient was required to undergo open thoracic and thoracoabdominal aortic repair due to impending rupture of the aorta. Moreover, the abdominal aortic graft was rereplaced due to debranching graft occlusion of the coeliac artery and the left renal artery. [ABSTRACT FROM AUTHOR]

SummaryBackground: It remains unclear when to recommend operation for an asymptomatic abdominal aortic aneurysm (AAA). This study examined a prospective series of patients for whom standard criteria were applied. Methods: Some 584 consecutive patients with an AAA of diameter 3 cm or greater detected by ultrasonographic screening have been observed for up to 14 years. Repeat ultrasonographic examinations have been performed at intervals. Surgery was not considered unless the aneurysm measured 6 cm in diameter, expanded at a rate equivalent to at least 1 cm per year, caused the patient symptoms, or an iliac aneurysm was present that required treatment. Results: Operation was performed on 127 patients; the majority (80; 63 per cent) had an aneurysm that reached 6 cm in diameter. Use of the above criteria prevented rupture in all but 24 (4 per cent) of the 584 patients over the 14-year interval. Of these 24 patients, 11 were unfit for planned surgery and eight declined operation or follow-up. Rupture in the five remaining patients (1 per cent) who were available for treatment compared favourably with the reported 30-day mortality rate for elective surgical treatment of 1·4–12 per cent. Conclusion: Repeated observation is preferable to surgical intervention until an aortic aneurysm measures 6 cm in diameter, expands by 1 cm per annum or causes symptoms.

SummaryBackground: This prospective study compared morbidity and mortality rates following conventional and endovascular abdominal aortic aneurysm (AAA) repair using a physiological scoring system. Methods: Between December 1994 and November 1997, 104 elective open aneurysm repairs and 49 endovascular aneurysm repairs were performed. These patient cohorts were compared using the Portsmouth predictor equation (P-POSSUM) scoring system. Data collected prospectively from patient notes were used to obtain physiological and operative severity scores which were analysed to compare expected and observed mortality and morbidity rates. Results: There were three deaths (6 per cent) in the endovascular AAA repair group and 17 (16 per cent) in the conventional aneurysm repair group, whereas the P-POSSUM formulae predicted mortality rates of 8 and 19 per cent respectively. Although the mean physiological scores were similar for both groups (endovascular 20·8 versus conventional 20·1), the operative severity score was significantly greater in the conventional group (26·3 versus 19·7; P < 0·001). Conclusion: In this study open aortic aneurysm repair had a higher operative severity than endovascular repair, which was reflected in the increased mortality rate. [ABSTRACT FROM AUTHOR]

Background This study aimed to define the cause of death in patients undergoing elective infrarenal aortic reconstruction. Methods Members of the Joint Vascular Research Group who had collected details prospectively of patients undergoing elective aortic reconstruction provided information on those who died. Results Details of 3786 patients were obtained. Some 171 patients died (133 following abdominal aortic aneurysm (AAA) and 38 after aortofemoral bifurcation graft (AFBG) for occlusive disease). The mortality rate following AAA repair was 4·8 per cent, rising to 16 per cent if repair was combined with either renal or distal reconstruction (P<0·001). Similar results were obtained with AFBG (3·4 and 11 per cent respectively, P<0·001). The first major complication encountered was cardiac (39·8 per cent), followed by bleeding (20·5 per cent), respiratory (13·5), and gut (5·3 per cent), or limb ischaemia (6·4 per cent). Bleeding was commoner following reconstruction for aneurysm compared with that for occlusive disease (P<0·05). Eighty-six patients (50·3 per cent) died from the first major complication. Of the remainder, 45 (53 per cent) developed multisystem organ failure (MSOF). The most commonly involved systems were cardiac, respiratory and renal. Conclusion Cardiac problems were the major cause of death following infrarenal aortic reconstruction. MSOF is the ‘final common pathway’ in about half of the patients who survive the initial complication. [ABSTRACT FROM AUTHOR]

The author discusses the guidelines on the surgery for the aneurysms of the ascending aorta. The author states that aneurysms of the ascending aorta must need to be attacked surgically to prevent catastrophic events such as aortic dissection and aortic rupture. He mentions that the size of the aneurysm, the body surface area, and the experience of the surgical team are of paramount importance.

Background Despite the theoretical advantages of coating knitted grafts with a material designed to reduce blood loss, their performance has not been directly compared with woven grafts in a prospective randomized trial. The aim of this study was to compare the graft handling qualities and operative blood loss of the two types of arterial prosthesis, as well as complication rate and patient survival at 1 year. Methods A total of 267 consecutive patients having surgery for occlusive or aneurysmal disease of the aortoiliac arteries were randomized to receive woven (141 patients) or knitted collagen-impregnated Dacron (126 patients) grafts. Graft patency was assessed on discharge and at 1 year by duplex imaging. Results Mean(s.d.) intraoperative blood loss was statistically greater with woven grafts (1690(1424) ml) compared with knitted (1363(1172) ml) (P=0·049). An insignificant 1-year increase in mean(s.d.) graft diameter of 1·2(0·2) mm was found at the distal anastomosis in the knitted group. There was no difference in graft patency between the groups and only one graft became infected. Conclusion This study suggests that knitted and woven grafts have similar clinical performance and therefore the less expensive material (woven) should usually be selected unless haemorrhagic complications are anticipated.

Background Brothers of patients with an abdominal aortic aneurysm (AAA) are at high risk. In the present study brothers of patients who underwent elective AAA surgery were invited for aneurysm screening and the psychological consequences studied. Methods All brothers over the age of 50 years were invited for abdominal ultrasonography. They were asked to complete a standard psychological well-being questionnaire both before, and 3 months after screening. Results Some 571 brothers were identified: 251 were dead, 35 lived abroad, 16 could not be contacted for other reasons, 46 refused to participate and 13 were already known to have an AAA. Some 210 subjects (37·8 per cent) accepted the offer of screening. A new AAA was detected in 26 (12·3 per cent, 95 per cent confidence interval 8–18 per cent) of the men screened resulting in an overall prevalence of 18 per cent (95 per cent confidence interval 13–26 per cent). Eight (3·8 per cent) aneurysms were 5 cm or more in diameter and elective surgery was performed in five patients (2·4 per cent). The psychological dimensions of well-being (depression, anxiety, energy, and positive well-being) had not changed significantly 3 months after screening. Conclusion The prevalence of AAA in brothers of patients with AAA is far higher than in the overall male population of the same age. Screening does not seem to have a negative influence on psychological well-being. [ABSTRACT FROM AUTHOR]

The author comments on the study "Too thin a beam of light in thick fog," by Alessandro Della Cortea and Amalia Forteb. The author states that the study investigates the thickness of aortic media in patients undergoing aortic surgery. The author adds that researchers revealed thinner aortic media in patients with aortic dissection than those with aortic aneurysm.

The article discusses research about the health span of patients who underwent personalized external aortic root support (PEARS) to manage Marfan syndrome. Topics mentioned include the possibility of PEARS to prevent the repetitive stress of systo-diastolic distension of the aortic wall, negative consequences of PEARS such as intense inflammatory reaction, and factors that need to consider to lessen the hesitation of patients about PEARS.

In this article, the author focuses on the use of elective arch repair as a low-risk procedure in patients with aortic arch. It mentions that high incidence of concomitant relevant surgery consists coronaries and mitral valve in patients. It also mentions the use of perfusion techniques such as cannulation sites or other technical considerations in aortic arch surgery.

The article offers information on ascending aorta elongation along with the risk of dissection associated with it. It mentions aortic dissection in cases of coronary artery disease and valve disease. It also mentions the risk of acute aortic syndrome associated with patients undergoing ascending aorta surgery.

This article explains that there is poor prognosis for patients with ruptured thoracic aorta based on the classic study of Parmley et al., who investigated victims of the Korean war in the 1950s. The usual cause of injury to thoracic aorta is deceleration trauma. Recent studies on road traffic accident victims show that 9-19 percent can expect to survive to reach hospital. Choosing an appropriate operative strategy can reduce the complications in aortic rupture surgery.
