Objective: Major lower limb amputation is generally associated with a high risk of early and late-term mortality. In this study, 30-day, one-year and three-year mortality of non-traumatic major lower extremity amputations and comorbidities affecting the mortality rate were investigated., Method: Patients who underwent a major lower limb amputation secondary to diabetes or peripheral artery disease between the years 2010-2015 were retrospectively evaluated. Additional to patient demographic data and comorbidities, amputation level, survival and mortality time were extracted. Mortality rates after 30 days, one year and three years were analysed. The associations of the survival to different parameters were evaluated with Kaplan-Meier analysis and log rank test, while the impact of the risk factors on mortality was evaluated with the Cox regression test., Results: A total of 193 patients were enrolled in the study. Approximately 60% of patients were aged ≥65 years, and 65.8% were male. Below-knee amputation was performed in 64.8% of patients and above-knee amputation in 35.2% of patients. The mean follow-up of patients was 29.48 months (range: 0-101 months). After non-traumatic major lower extremity amputation, 30-day, one-year and three-year mortality were 16.6%, 38.3% and 60.1%, respectively. On Cox regression analysis, age ≥65 years was the only variable that had significant impact on the 30-day mortality (hazard ratio (HR): 3.4; p=0.012), while age ≥65 years (HR: 2.5, p=0.000), diabetes (HR: 2, p=0.006) and renal failure (HR: 2, p=0.001) were found to have significant impacts on three-year mortality., Conclusion: The findings of this study showed that >50% of patients with non-traumatic major lower limb amputations died within three years. Advanced age, diabetes and renal failure were the risk factors that increased the mortality. The high mortality rates revealed the importance of employing all hard-to-heal wound treatment options before making an amputation decision. Further, prospective studies are needed to determine the effects of primary disease status and timing of amputation on mortality.

Objective: To compare the results of endovascular therapy for chronic limb-threatening ischemia (CLTI) in patients categorized under the gray and yellow zones of the patient risk, limb severity, and anatomic pattern (PLAN) concept over a 2-year follow-up period., Methods: Patients who underwent endovascular therapy for peripheral artery disease and presented with CLTI from February 2017 to February 2019 were retrospectively reviewed. The patients were grouped into yellow and gray zones based on the PLAN concept. Preoperative and postoperative walking distances, Rutherford classes, and postoperative target vessel patency rates were recorded and compared between the groups. Follow-up evaluations were performed at 1, 6, 12, and 24 months post-procedure., Results: Of the 387 patients evaluated, the yellow and gray groups comprised 88 patients each. The overall patency rates were similar between the groups (84 (95.45%) vs. 81 (92.05%), respectively). The occlusion-/stenosis-free survival times, amputation-free survival time, and mean survival time were not significantly different. However, the gray group had a significantly higher number of atherectomy interventions (74 vs. 59) and crosser devices used (62 vs. 42)., Conclusion: Endovascular therapy is an effective treatment option for patients in the gray zone of the PLAN color coding system., Competing Interests: Declaration of conflicting interestsThe authors declare that there is no conflict of interest.

Objectives: The aim of this study is to evaluate the safety and efficacy of the novel bidirectional cannula that ensures stable distal perfusion compared to conventional cannula in patients undergoing femoral arterial cannulation for cardiopulmonary bypass (CPB)., Methods: During a 1-year period, 64 patients undergoing surgery via peripheral cannulation were prospectively randomized to receive 19 F bidirectional (Biflow™, LivaNova, Italy) or 19 F conventional (HLS Peripheral cannula, Getinge Group™, Germany) cannula with 6 F downstream line (Bicakcilar™, Turkey) for femoral artery cannulation. The primary outcome included the efficacy (adequacy of antegrade/retrograde comparative flow via cannula measured by doppler ultrasonography) and the secondary outcome was the safety (early/late complications and adverse events)., Results: Percent flow (distal/proximal) after cannulation measured by doppler ultrasonography was significantly better in study group (33.1 ± 5 ml/min) versus downstream cannula (16.1 ± 4, p = 0.012). SpO 2 measured by near infrared spectroscopy (NIRS) also demonstrated significantly better saturation in distal calf of the cannulated leg in bidirectional cannula group (67.5% ± 10% vs 52.5 ± 8, p = 0.04). The incidence of serious adverse events was seroma on femoral region (one patient), superficial wound infection (one patient), pseudo-hematoma (two patients) in bidirectional cannula group and in-hospital femoral embolectomy/artery repair (two patients), superficial wound infection (three patients), cannulation site hematoma (three patients) in conventional cannula group., Conclusions: This study demonstrates that in patients undergoing femoral arterial cannulation for CPB during cardiac surgery, the use of a novel bidirectional cannula is safe and easy to insert and provides stable distal perfusion of the cannulated limb.

The authors performed a detailed retrospective analysis of diabetic patients undergoing isolated coronary artery bypass graft surgery aiming to investigate the association of the preoperative glycosylated hemoglobin with occurrence of postoperative atrial fibrillation. Although statistical analysis showed a weak relationship between HbA1c values of 9.06% or above and postoperative atrial fibrillation (PoAF), they concluded that serum level of HbA1c could not be used as a predictor for the development of PoAF. But there are many questions to be asked and answers to be found., (© 2022 Wiley Periodicals LLC.)

The authors conducted a prospective, observational study to evaluate the correlation of fluid responsiveness with commonly used carotid Doppler-derived indices like carotid artery blood flow, carotid corrected flow time, respirophasic variation in carotid artery blood flow peak velocity in patients undergoing coronary artery bypass grafting. They claimed that altough only ΔVpeak demonstrated some predictive power with areas under receiver operating characteristic of 0.671, carotid Doppler ultrasound indices were found to be not dependable as a substitute for invasive methods to assess fluid responsiveness. The presence of studies advocating quite different sentiments in the literature regarding feasibility and reliability show that there is a long way gone and a long way to go., (© 2022 Wiley Periodicals LLC.)

Background: We have analyzed our single-center immediate and follow-up results in the management of acute iliofemoral deep vein thrombosis (IFDVT) using pharmacomechanical catheter-directed thrombolysis (PMCDT) to determine the safety, accuracy, and effects on quality of life and whether this treatment strategy prevents post-thrombotic syndrome (PTS)., Methods: The cases of 230 patients who had undergone PMCDT to treat IFDVT from January 2017 to December 2018 were retrospectively reviewed. The preoperative, operative, and postoperative variables, Marder scores, outcomes, and follow-up assessments with the Villalta score and venous clinical severity score were investigated., Results: Anatomic success was achieved for 95.2% of the 230 patients. The mean Marder score had decreased from 12.65 ± 2.1 to 2.4 ± 1.3 postoperatively (P < .01). Early recurrent thrombosis had developed in 13 patients (5.65%). The primary patency at the 1-, 6-, and 12-month follow-up visits was 94.0%, 87.2%, and 81.7%, respectively. From 1 to 6 months, the Villalta score had decreased from 8.32 ± 4.14 to 3.43 ± 0.61 and the venous clinical severity score had decreased from 4.0 ± 1.8 to 1.82 ± 0.36 (P < .05). No statistically significant difference was found in the PTS severity scores at 12 months of follow-up compared with at 6 months. The mean change in the venous disease-specific quality of life from baseline to 12 months was 29.41 ± 1.99 (P = .029). The total recurrence rate was 19.63% at 1 year., Conclusions: For a select group of patients with acute IFDVT, the use of PMCDT and postoperative anticoagulation therapy offered significant reductions in clot burden, leg pain, and swelling, achieving a significant reduction in PTS severity scores at 6 months., (Copyright © 2021 Society for Vascular Surgery.

The authors present a revolutionary study aiming to evaluate the effect of alterations in potassium concentrations in transfused packed red blood cells (PRBC) on the neonate and infant potassium levels after congenital cardiac surgery. By establishing a strict protocol that restricts the rate of transfusion, the age of the transfused PRBC, and not transfusing a PRBC with a potassium level above 15 mmol/L, they accomplished to suggest a safe and easy way for preventing transfusion-associated hyperkalemia., (© 2021 Wiley Periodicals LLC.)

Aim: Postoperative bleeding is a significant cause of morbidity and mortality in patients undergoing cardiac surgery. Studies have been conducted, and guidelines have been published regarding patient blood management and aiming to prevent blood loss in the perioperative period. Various bleeding risk assessments were developed for preoperative period. We aimed to examine the correlations of scoring systems in the literature with the amount of postoperative bleeding in patients undergoing first time coronary artery bypass graft surgery, and to show the most suitable preoperative bleeding risk assessment for coronary artery bypass graft patients., Methods: The study included 550 consecutive patients who underwent coronary artery bypass graft operation. The inclusion criteria were considered as patients to be older than 18 years old and to undergo elective or emergent myocardial revascularization using cardiopulmonary bypass. All variables required for scoring systems were recorded. The initial results of the study were determined as the amount of chest tube drainage, the use of blood products, the change in hematocrit level, reoperation due to bleeding, duration of ventilation, duration of intensive care unit stay, and hospital stay. Mortality which occurred during first 30 days after operation was considered as operative mortality. Operative mortality was accepted as the primary endpoint. Secondary endpoints were massive bleeding and high amount of transfusion., Results: Data were obtained from a series of 550 consecutive patients treated with isolated coronary artery bypass graft. It was seen that PAPWORTH and WILL-BLEED risk assessments responded better for E-CABG grade 2 and 3 bleeding compared to other risk assessments. TRACK, TRUST, and ACTA-PORT scales were found to have low ability to distinguish patients with E-CABG bleeding grade 2 and 3., Conclusion: Predicting postoperative bleeding and transfusion rates with preoperative risk scores in patients undergoing coronary artery bypass graft surgery will provide valuable information to physicians for establishing a proper patient blood management protocol and this will decrease excessive transfusions, unnecessary reoperations as well as improve postoperative outcomes.

We present our multidisciplinary and multistep strategy in patients undergoing minimally invasive aortic valve replacement (mAVR) on minimally invasive extracorporeal circulation (MiECC) compared with control groups of a single strategy and conventional techniques. This cohort study included high-risk patients (Society of Thoracic Surgeons [STS] risk score >8%) undergoing aortic valve surgery under different strategies during the period from January 2017 until March 2019. Patients were matched for age, gender, body mass index, and STS score: group 1 (MiAVR) based on a minimally invasive technique with J-mini-sternotomy, rapid deployment valve (RDV), and type IV customized MiECC; group 2 (control-mAVR) consisted of minimally invasive technique with only J mini-sternotomy and RDV on a conventional extracorporeal system; group 3 (control-MiECC): full sternotomy and type IV customized MiECC; and group 4 (control): full sternotomy on a conventional extracorporeal system. The MiAVR group had significantly less duration of x-clamp time ( 35.4 ± 11 minutes), postoperative respiratory support (4.1 ± 1 hour), postoperative hemorrhage (250 ± 50 mL), and intensive care unit stay (1 ± .5 days) than the control-conventional (group 4) group. Seventy-six percent of patients did not receive any blood products in MiAVR ( p = .025 vs. group 4). Incidence of atrial fibrillation (8%) and low cardiac output (14%) in MiAVR were significantly better than control. Critics of minimally invasive techniques sustain that potential advantages are offset by a longer cross-clamp and cardiopulmonary bypass duration, which may translate into inferior clinical outcomes. We advocate that our multidisciplinary approach supported by multiple technologies may be associated with faster recovery and superior outcomes than conventional minimally/conventional techniques., (© Copyright 2020 AMSECT.)

Background: The primary objective of this study was to test and compare the efficacy of currently available intraoperative blood salvage systems via a demonstration of the level of increase in percentage concentration of red blood cells (RBC), white blood cells 9WBC) and platelets (Plt) in the end product., Methods: In a prospective, randomized study, data of 80 patients undergoing elective cardiac surgery with cardiopulmonary bypass in a 6-month period was collected, of which the volume aspirated from the surgical field was processed by either the HemoSep Novel Collection Bag (Advancis Surgical, Kirkby-in-Ashfield, Notts, UK) (N=40) (Group 1) or a cell- saver (C.A.T.S Plus Autotransfusion System, Fresenius Kabi, Bad Homburg, Germany) (N=40) (Group 2)., Results: Hematocrit levels increased from 23.05%±2.7 to 43.02%±12 in Group 1 and from 24.5±2 up to 55.2±9 in Group 2 (p=0.013). The mean number of platelets rose to 225200±47000 from 116400 ±40000 in the HemoSep and decreased from 125200±25000 to 96500±30000 in the cell-saver group (p=0.00001). The leukocyte count was concentrated significantly better in Group 1 (from 10100±4300 to 18120±7000; p=0.001). IL-6 levels (pg/dL) decreased from 223±47 to 83±21 in Group 1 and from 219±40 to 200±40 in Group 2 (p=0.001). Fibrinogen was protected significantly better in the HemoSep group (from 185±35 to 455±45; p=0.004)., Conclusions: Intraoperative blood salvage systems functioned properly and the resultant blood product was superior in terms of red blood cell species. The HemoSep group had significantly better platelet and leukocyte concentrations and fibrinogen content.

Background: Despite the recent introduction of a number of technical and pharmacologic blood conservation measures, bleeding and allogeneic transfusion remain persistent problems in open-heart surgical procedures. Efforts should be made to decrease or completely avoid transfusions to avoid these negative reactions., Methods: Our coronary artery bypass grafting database was reviewed retrospectively and a total of 243 patients who underwent cardiac surgery with cardiopulmonary bypass (CPB) were studied in a 12-month period (January-December 2016) after the implementation of the new program, and compared with 275 patients of the previous 12-month period.All the staff involved in the care of the patients were educated about the risks and benefits of blood transfusions and the new transfusion guidelines in a 45-min training. We revised our guidelines for transfusions based on the STS. A transfusion log was created. Reduction in IV fluid volume was targeted. CPB circuitry was redesigned to achieve significantly less prime volume. Results: The proportion of patients transfused with red blood cells was 56% (n =154) in the control group and reduced by 26.8% in the study group (29.2%; 71 patients; P < .01). Blood transfusion rate (1.7 ± 1/3.05 ± 1 units), postoperative hemorrhage (545 ± 50/ 775 ± 55 mL), respiratory support duration (12.4 ± 7/16.8 ± 8 h) and ICU stay (2.2±1.1/ 3.5±1.2 days) were significantly better in the blood conservation group.  Conclusion: These findings, in addition to risks and side effects of blood transfusion and the rising cost of safer blood products, justify blood conservation in adult cardiac operations.

Objective: One thousand consecutive patients who underwent endovascular repair in an 8-year period were studied retrospectively to evaluate technical success, freedom from reinterventions, early clinical outcome, and risk factors for restenosis/occlusion., Methods: Mean ± SD Rutherford class was 3.29 ± 0.8. A total of 755 patients have claudication, 423 from rest pain, and 569 from ischemic ulceration., Results: A total of 552 men and 448 women (mean ± SD = 69.84 ± 8 years; range = 19-89 years) underwent endovascular repair. A total of 698 patients received local anesthesia and 302 general anesthesia. A total of 447 patients received percutaneous transluminal angioplasty, 650 stents were placed; 231 atherectomies were performed and 171 patients received hybrid approach. The procedure was successful in 847 patients (84%). There was no early death. There were 151 early occlusions (95 underwent surgery, 56 received stents), 121 dissections (39 underwent surgery, 56 received stents and 26 medical treatment), 32 hematoma, and 13 early leaks. Mean ± SD Rutherford class improved to 3.02 ± 0.9. Freedom from reintervention rate at 8 years was 76%. A total of 63 patients underwent surgery and 59 cellular therapy. A total of 134 finger, 142 below-knee, and 29 above-knee amputations were reported., Conclusions: Endovascular interventions can be performed with a satisfactory technical success and low complication rates; however, nonfatal complications and catheter-based reinterventions are frequent.

Objective: The limitation of alternative transfusion practices in infants increases the benefits of blood conservation. We analyzed the efficacy of a structured program to reduce transfusions and transfusion-associated complications in cardiac surgery PATIENTS AND METHODS: Our pediatric surgery database was reviewed retrospectively, comparing outcomes from two different time periods, after the implementation of an effective blood conservation program beginning in March 2014. A total of 214 infants (8.1±3.4 months) who underwent biventricular repair utilizing CPB (Group 1 - Blood conservation) were studied in a 12-month period (March 2014-February 2015) after the implementation of the new program, and compared with 250 infants (7.91±3.2 months) (Group 2 - Control-No blood conservation) of the previous 12-month period (March 2013-February 2014)., Results: The proportion of patients transfused with red blood cells was 75.2% (N=188) in control group and reduced by 16.4% in the study group (58.8% - 126 patients, p <0.01). The mean number of transfusions was 1.25 ± 0.5 units per patient in control group and decreased to 0.7 ± 0.5 units per patient after the start of the program (p = 0.035). Cerebral oximetry demonstrated better follow-up during the operative period confirming less hemodilution in Group 1. Respiratory support, inotropic need and ICU stay were significantly better in the study group., Conclusions: These findings, in addition to attendant risks and side effects of blood transfusion and the rising cost of safer blood products, justify blood conservation in pediatric cardiac operations. Circuit miniaturization, ultrafiltration, and reduced postoperative bleeding, presumably secondary to higher fibrinogen and other coagulation factor levels, contributed to this outcome.

Aim: Paraplegia due to ischemia-reperfusion (I/R) injury of the spinal cord is a devastating complication of thoracoabdominal aortic surgery. Cysteinyl leukotrienes are potent mediators of inflammation that are associated with I/R injury. The present study was designed to investigate the role of montelukast, a selective reversible CysLT1 receptor antagonist, on spinal cord I/R injury in an experimental model., Material and Methods: Twenty-one male Sprague-Dawley rats were randomly assigned to three groups (n=7 per group) as G1 (no aortic occlusion and montelukast administration), G2 (45 min. aortic occlusion; no montelukast administration) and G3 (45 min. aortic occlusion, 10 mg/kg montelukast administration). After neurologic evaluation using the Motor Deficit Index (MDI) score at the 48th hour of reperfusion, lumbar spinal cords were removed for histopathological evaluation and immunohistochemical staining for HSP70, interleukin-6 and myeloperoxidase (MPO)., Results: All rats in the G1 group had a normal neurological status and their MDI score was 0 (p < 0.05). The MDI score of G3 was significantly lower than G2 group (2.8 vs. 5.5; p < 0.05). Vacuolar congestion was found to be significantly lower in G1 than the other groups (p=0.0001). The interleukin-6 receptor level was found to be significantly lower in G3 group than the control group (p=0.013). There was no statistically significant difference found among the groups in terms of the degree of HSP70 and MPO staining., Conclusion: Increased generation of leukotrienes in postischemic organs play an important role in I/R injury. The findings of the current study demonstrated that montelukast improved motor recovery and decreased IL-6 levels in spinal cord I/R injury.

Left ventricular pseudo-aneurysms develop when cardiac rupture is contained by pericardial adhesions or scar tissue due to myocardial infarction, surgery, trauma or infection. Left ventricular pseudo-aneurysms are uncommon, difficult to diagnose and prone to cardiac rupture. Urgent surgical repair is recommended. Here we report on a case of a large left ventricular pseudo-aneurysm on the anterolateral wall due to a previous anterior myocardial infarction, and its successful repair using the on-pump beating-heart technique.

Objective: Early and medium-term improvement of functional capacity and regression of left ventricular hypertrophy was evaluated in the young adult patient group following application of 21 mm or 23 mm bileaflet aortic mechanical valve prosthesis due to aortic stenosis. Methods : Twenty two patients (10 male, 12 female; mean age 27+-8.2 (19-43)) who underwent isolated aortic valve replacement due to rheumatic aortic stenosis, were included in the study. 21 mm and 23 mm bileaflet mechanical prosthesis was used respectively in eight and fourteen patients. The mean body surface area was 1.86 m(2) and 1.68 m(2) respectively in 23 mm and 21 mm prosthesis while 1.73 ±0.25 m(2) for the whole group. Functional capacity was New York Heart Association (NYHA) class II in 9 patients and class III in thirteen patients. Implantation was performed without enlarging the aortic root in all except four patients. In all patients transvalvular gradients, effective orifice area and the diameter of left ventricle were measured with transthoracic echocardiography during rest and after maximal exercise. Mean follow-up was 34±12 months (range 11-57 months)., Results: There were no postoperative complications or deaths. All the patients were assessed as NYHA class I with regards to functional capacity (p=0.01). Significant improvements were determined in postoperative mean transvalvular gradient (p=0.005) and left ventricular mass index (p=0.01) when compared with preoperative values., Conclusion: Our findings show that replacement with 21 mm and 23 mm mechanical prosthesis provides a significant improvement in regression of symptoms and increase of functional capacity in young adults in early and mid-period without increasing mortality and morbidity.

Since the first successful application of the heart-lung machine in 1953 by John Gibbon [1], great efforts have been made to modify the bypass techniques and devices in order to allow prolonged extracorporeal circulation in the intensive care unit (ICU), commonly referred to as extracorporeal membrane oxygenation (ECMO). ECMO uses classic cardiopulmonary bypass technology to support circulation. It provides continuous, non-pulsatile cardiac output and extracorporeal oxygenation [2]. Veno-venous ECMO (VV ECMO) provides respiratory support, while veno-arterial ECMO (VA ECMO) provides cardio-respiratory support to patients with severe but potentially reversible cardiac or respiratory deterioration refractory to standard therapeutic modalities. ECMO is a temporary form of life support providing a prolonged biventricular circulatory and pulmonary support for patients experiencing both pulmonary and cardiac failure unresponsive to conventional therapy. Despite the advent of newer ventricular assist devices that are more suitable for long term support, ECMO is simple to establish, cost-effective to operate., (Copyright © 2013 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).

Introduction: Modern surgical management of chronic venous insufficiency is possible since the development of catheter-based minimally invasive techniques, including radiofrequency ablation (RFA) and the application of colour Doppler sonography. RFA technology requires the use of tumescent anaesthesia, which prolongs the operating time. Instilling tumescent anaesthesia percutaneously below the saphenous fascia is the steepest part of the learning curve. In our study, we compared operative and postoperative results of tumescentless RFA and RFA with tumescent anaesthesia, to investigate the necessity of tumescent anaesthesia., Methods: A total of 344 patients with Doppler-confirmed great saphenous vein insufficiency underwent RFA between January and December 2012. Patients were divided into two groups according to anaesthetic management. Group 1 consisted of 172 patients: tumescent anaesthesia was given before the ablation procedure, and group 2 contained 172 patients: a local hypothermia and compression technique was used; no tumescent anaesthesia was administered. The visual analogue scale (VAS) was used and ecchymosis scores of the patients were recorded. Clinical examinations were performed at each visit and Doppler ultrasonography was performed in the first and sixth month., Results: Mean ablation time was significantly lower in group 2 compared to group 1 (7.2 vs 18.9 min; p < 0.05). Skin burn and paresthesia did not occur. The immediate occlusion rate was 100% for both groups. No significant difference was found between the groups in terms of VAS and ecchymosis scores. All patients returned to normal activity within two days. The primary closure rate of group 1 was 98.2% and group 2 was 98.8% at six months, and there was no significant difference between the groups (p > 0.05)., Conclusion: Eliminating tumescent infusion is a desirable goal. Tumescentless endovenous RFA with local hypothermia and compression technique appears to be safe and efficacious. Our technique shortens the operation time and prevents patient procedural discomfort.

Background: Paraplegia due to ischemia/reperfusion (I/R) injury of the spinal cord is a devastating and undesired complication of thoraco-abdominal aortic surgery. Unidentified clots cause a variety of thromboembolic events and deteriorate the severity of ischemia. We investigated the effect of the degree of anticoagulation on spinal cord I/R injury and whether heparin is protective against I/R injury beside its anticoagulant properties., Materials and Methods: Twenty-eight rats were randomly assigned to four groups (n=7 per group) as G1 (no aortic occlusion and heparin administration), G2 (45 min aortic occlusion; no heparin administration), G3 (45 min aortic occlusion; 400 IU/kg heparin to keep activated clotting time (ACT) level around 200 sec), and G4 (45 min aortic occlusion; 800 IU/kg heparin to keep ACT level around 600 sec). After neurologic evaluation at the 48th hour of reperfusion, lumbar spinal cords were removed for histopathologic evaluation and immunohistochemical staining for HSP70 (heat shock protein 70), interleukin-6 and myeloperoxidase (MPO)., Results: The Motor Deficit Index (MDI) scores were lowest in G1 group (p < 0.05) and the MDI scores of G3 and G4 were significantly lower than G2 group (p < 0.05). The neuronal degeneration in G3 was significantly lower than the other groups, respectively (p = 0.03). Histopathological evaluation showed no significant intergroup differences in terms of the degree of edema and inflammatory response. There was no statistically significant difference found among the groups in terms of HSP70 staining, IL-6 staining or the degree of MPO staining., Conclusions: Protection of spinal cord from I/R injury requires a multimodal management. We should not miss out the importance of adequate anticoagulation in thoraco-abdominal surgical procedures. Furthermore, the recently discovered anti-inflammatory property of glycosaminoglycans, including heparin, deserves to be investigated.

Background and Aim: Postoperative neurologic deficit is the most devastating complication after surgical thoracic aorta repair. Cerebrospinal fluid drainage and some medications are used for spinal cord protection during and after the operation., Methods: A 25-year-old patient applied to our clinic with a traumatic descending aortic aneurysm. We performed a surgical repair for the aneurysm but could not achieve to place a lumbar catheter to provide cerebrospinal fluid drainage. Levosimendan was chosen for spinal cord ischemic preconditioning because of its vasodilatory effects., Results: Postoperative course was uneventful. Hemodynamic and neurologic complication was not observed, and the patient was discharged from the hospital in the postoperative 5th day., Conclusions: Levosimendan can be used for preconditioning and spinal cord protection from ischemic injury during descending aorta repair. We clearly benefit from the vasodilator peculiarity of the drug for improving spinal cord perfusion.
