To compare the level of inflammatory markers and endothelial function 24 hours (Day1) and 90 days (Day90) after conventional quadrant-wise (Q-SRP) versus one-stage full-mouth scaling (FM-SRP) in patients affected by type 2 diabetes mellitus (T2DM).Patients affected by periodontitis and T2DM were randomly allocated to receive FM-SRP or Q-SRP and followed up at Day1 and Day90. Serum samples, vital signs and flow-mediated dilation (FMD) parameters were collected at baseline, Day1 and Day90. Periodontal variables were collected at baseline and Day90. The primary outcome was the C-reactive Protein (CRP) concentration at Day1 after periodontal treatment. The Student t-test for independent samples was used for between-group comparisons (Mann Whitney U test for non-normal data), while the ANOVA with post-hoc Tukey tests (Kruskal Wallis and Dunn tests for non-normal data) were used for intragroup comparisons.40 subjects were included. FM-SRP produced a significant increase in CRP and a significant reduction in FMD at Day1 compared to Q-SRP (p0.05). The absolute change in HbA1c (mmol/mol) from baseline to Day90 was significantly improved in the Q-SRP (ΔHbA1c=-1.59 (SD=1.20)) compared to the FM-SRP group (ΔHbA1c=-0.8 (SD=0.95)) (p=0.04).FM-SRP triggers a robust acute-phase response at 24 hours after treatment compared to Q-SRP. Such systemic acute perturbations may offset the benefic systemic effects of periodontal treatment in terms of HbA1c reduction and improvement in endothelial function in T2DM subjects.

To compare the level of inflammatory markers, oral health-related quality of life (OHRQoL), and gingival parameters 1 month after introduction of electric toothbrush and intensive oral hygiene manoeuvre adaptation (OHI) versus routine habits (no-OHI) in patients affected by generalized gingivitis.One hundred forty subjects with generalized gingivitis were randomized to receive either OHI or no-OHI. Full-mouth plaque/bleeding scores (FMPS/FMBS), serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and an oral health impact profile-14 questionnaire were collected at baseline and at 1-month follow-up visit.In the OHI, a significant FMPS and FMBS reduction (p .01), a significant intra-group decrease in hs-CRP and IL-6 (p .01), and a significant improvement of OHRQoL (p .01) were noted at 1-month follow-up visit. In the no-OHI, lower-magnitude differences were noted only for oral parameters. Resolution of gingivitis varied between OHI and no-OHI (89% vs. 7%, respectively, p .01). A logistic multivariate regression suggested that FMBS ≤8% was associated with the odds ratio of 13, having both CRP and IL-6 below the selected threshold for healthy young adults (p = .04).Gingivitis resolution determined important reductions of gingival inflammation and plaque levels, as well as systemic inflammatory markers and an improvement of quality of life (NCT03848351).

To determine the efficacy of four different oral hygiene protocols involving adjunctive interdental devices in terms of plaque and bleeding scores in periodontitis-affected patients.This was a randomized clinical trial with a 5-week follow-up, including previously treated periodontitis patients not undergoing any supportive care. Patients were randomly allocated to 4 groups: manual toothbrush (group TB); toothbrush plus dental floss (group TB/F); toothbrush plus interdental brushes (group TB/IDB) and toothbrush plus rubber interdental picks (group TB/RIDB). Oral hygiene instructions (OHI) were provided at baseline (T-7) and at T0 (1-week) then bi-weekly (T14/T28). At T0, supragingival professional cleaning was delivered. Plaque and bleeding indexes were taken at all timepoints by a single calibrated examiner, blind to group allocation.At T-7, patients were comparable for age, body mass index (BMI) and all clinical parameters, exceptions for the Interdental Angulated Bleeding Index. At T28, significant reductions of plaque and gingival inflammation were noted in all groups (p 0.001) and within the expected ranges. Intergroup comparisons identified that group TB/IDB and group TB/RIDB achieved lower levels of plaque and inflammation than group TB (p 0.05). Group TB/IDB and group TB/RIDB showed lower levels of plaque and lower inflammation as measured by angulated bleeding index than group TB/RIDB (p 0.05).Interdental brushes and rubber interdental picks were more efficient than toothbrushing alone and toothbrushing and floss in reducing plaque and gingival inflammation measured in a periodontitis-affected population.

Background To report the early outcomes of cone beam computed tomography (CBCT) using last generation 3D C-arm in patients undergone advanced endovascular aortic aneurysm repair (AdEVAR) and to identify risk factors that may predict any un-planned procedures. Methods Patients undergone AdEVAR between December 2017 and December 2018 were enrolled. Final CBCT was performed in all patients after digital subtraction angiography. Primary end points were the incidence of any positive findings and the following unplanned procedures intended as any endovascular manoeuvre performed to fix such technical defect. The secondary endpoints were comparison of outcomes between patients with positive findings undergone unplanned procedure (Group A) versus patients without findings (Group B). Results 132 patients underwent endovascular treatment for aortic aneurysm. Of these, 22 (33%) fenestrated-branched endovascular aneurysm repairs (F-BEVAR), 21 (29%) EVAR with iliac branch devices, 19 (26%) abdominal and 10 (14%) thoracic EVAR were included in the study. Unplanned procedures after CBCT were necessary in 22 patients (31%). Patients in both groups were similar excepted for BMI >25 kg/m2 (55% vs. 26%), hostile iliac anatomy (64% vs. 32%) and previous aortic treatment (73% vs. 32%) (P Conclusion The use of CBCT, especially in challenging scenarios, can reveal technical defects and may potentially limit the need for late reintervention. Patients undergone previous aortic surgery should be carefully evaluated and routine CBCT should be performed.

Introduction To compare endoleak outcomes after thoracic endovascular aneurysm repair (TEVAR) with different stent-graft generations into long-term follow-up. Design retrospective, observational, and single-center cohort study. Methods TEVAR procedures performed between November 1995 and December 2020 were analyzed. The primary endpoint of this study was the freedom from endoleak (type I/III) in four stent-graft generations during the follow-up period. The first generation (GEN1) included: Vanguard; AneuRx and Talent; Stentor; Excluder; Endologix; EndoFit. The second generation (GEN2) included: TAG and TX. The third (GEN3) included: Relay Plus; Valiant Captivia; Zenith Alpha and custom-made. The fourth (GEN4) included: Relay Pro; Conformable C-TAG; Navion; E-Vita; Najuta; Nexus; standard and custom-made thoraco-abdominal devices. Nonaortic and aorta-related survival was considered as secondary outcome. Results A total of 509 TEVAR were included with a 44.3 ± 42.5 months mean follow-up. Freedom from endoleak at 5 years was 65.6%, 61.4%, 76.2%, and 69.1% for GEN1, GEN2, GEN3, and GEN4, respectively ( p = 0.368). The first two generations demonstrated a higher endoleak rate when compared with the two most recent ones (27.2 vs 18.2%, respectively; p = 0.043). GEN1 was an independent risk factor ( p = 0.014) and GEN4 was an independent protective factor ( p = 0.001) for endoleak. GEN1 was found to be a risk factor for type-Ia endoleak ( p = 0.059). GEN4 demonstrated a protective association regarding type-Ib endoleak ( p = 0.012). Overall survival was 75.3%, 44.4%, 27.2%, and 17.6% at 1, 5, 10, and 15 years, respectively. Survival distinguished as non-related versus aortic-related was 86.7% vs 23.5%, 52.7% vs 9.8%, 32.9% vs 2.0%, 21.2% vs 0% at 1, 5, 10, and 15 years, respectively ( p< 0.000). Conclusion Endoleak occurred in a non-negligible percentage of TEVAR patients. A significant reduction of endoleak incidence over evolving stent-grafts generations was registered. Newer stent-graft generations demonstrated better long-term endoleak. Data about long-term outcomes require ongoing updates to prove both the reliability and the durability of newer stent-graft generations.

Arch pathology represents one of the last frontiers in aortic aneurysms endovascular management. Several companies recently developed dedicated branched and fenestrated endografts specifically designed for the aortic arch, aiming to overcome some of the issues associated with standard thoracic endograft and supra-aortic vessels extra-anatomical debranching. This study aimed to evaluate early outcomes obtained with a custom-made fenestrated endograft approved for thoracic aortic aneurysms exclusion.All consecutive patients treated with the Najuta endograft (Kawasumi Laboratories, Inc, Tokyo, Japan) in Italy were prospectively enrolled and included in the study population. Anatomical characteristics and perioperative data were retrospectively analyzed. Study endpoints were technical success, 30-day clinical success, overall survival, supra-aortic vessel patency, endoleak and need for reintervention or surgical conversion.During the period 2018-2022, seventy-six patients received a Najuta endograft in Italy and were enrolled in the study. Median age was 72 (IQR 69-76) years and 80.3% were male. Most of the patients received treatment for atherosclerotic aneurysms (80.3%) while the others for post-dissection aneurysms (7.9%), penetrating aortic ulcer (9.2%), or type I endoleak correction after previous thoracic endovascular repair (2.6%). Overall, 161 supra-aortic vessels were preserved through a dedicated fenestration. Technical success was achieved in 74/76 (97.4%) of procedures; both failures were associated with endoleak detection at final angiography (one type I and one type III endoleak). Two distal migrations occurred during the implanting procedure. Clinical success at 30 days was 94.7%. Two early reinterventions were needed within 30 days after index procedure: in one case an aortic false lumen coils embolization was performed, since distal re-entry caused enlargement of the post dissection thoracic aneurysm. The other procedure consisted of a femoral pseudoaneurysm repair. Median follow-up was 7 (IQR 3-15) months; no supra-aortic vessel occlusions occurred and no patients needed surgical conversion.Early results suggest that in selected patients with aortic arch pathology needing a proximal landing, an endovascular approach with the Najuta system is safe and effective, especially for those at high surgical risk. A strict follow-up with high-quality computed tomography angiography images and eventual long-term complications evaluation is needed to confirm these initial experience findings.

Objective: The introduction of new endograft models improved long-term results of abdominal aortic aneurysm (AAA) endovascular repair (EVAR), but most of them maintained an old and unchanged design: a short body and long legs shifting up the flow divider. This study assessed the long-term results of EVAR with unimodular endoprosthesis fixed at the aorto-iliac bifurcation (Anatomical FiXation), in a large, unselected cohort. Materials and Methods: In a single-center, retrospective cohort study, 623 patients selectively treated between 1999 and 2016, were analyzed. Follow-up protocol included at least a computed tomography angiography within 3 months and a duplex ultrasound and clinical exam yearly. All enrolled patients were analyzed by 2020. The primary outcomes were technical success, clinical success, and survival. Secondary outcomes included survival-free from late-open-conversion (LOC), reintervention, and endoleaks. Results: Median age was 74±11 years and the follow-up 93±54 months. The technical success was achieved in 99.4% and the 30-day clinical success was 98.4%. A 5-year clinical success of 97.7% was registered and at 10 years success was 96.7%. The overall survival at 1, 5, 10, and 15 years was 92.4%, 79.5%, 64.9%, and 45.5%, respectively. Six (0.98%) AAA-related death were registered, 3 caused by infection of the endograft and 3 for secondary rupture. LOCs were 9 (1.47%) and reintervention-free survival at 1, 5, 10, and 15 years were 88.4%, 78.0%, 76.2%, and 74.6%, respectively. Freedom from endoleaks was 88.8% at 1 year and 72.7% at 15 years. A total of 63 high-flow endoleaks were registered (43 type I, 7 type IIIa, 12 type IIIb, and 1 type Ib+IIIb). No migrations were recorded, and the graft limb thrombosis rate was 1.14%. From a multivariate analysis resulted that long-term clinical success appeared to be reduced in patients affected by diabetes [odds ratio (OR) 0.24; p=0.04] and in presence of calcified and thrombotic iliac accesses (OR 0.16; p=0.006). Conclusion: EVAR with the Anatomical FiXation was confirmed to be safe, feasible, and effective to prevent AAA rupture in the long term as well. However, the overall survival remains afflicted by cardiovascular accident. The original concept of unibody bifurcated design allowed a very low rate of graft thrombosis and zeroed the risk of migration and related reintervention.

Mid-term durability of branches has already been established, and BF-branched and fenestrated endovascular repair has shown comparable results with open repair in the treatment of thoracoabdominal aortic aneurysms (TAAAs). Nevertheless, target vessel instability remains the most frequent adverse event after complex endovascular aortic repair. Type III endoleaks from directional branches have been reported with a low incidence, but risk factors for this complication have not been investigated yet.This was a dual-center observational retrospective cohort study. Data were collected prospectively for each patient treated with branched endovascular repair between April 2008 and December 2019. The primary outcome was to assess potential risk factors for branch disconnection and fracture. A logistic regression analysis was performed, including preoperative and postoperative measurements as well as intraoperative details. A Cox regression hazard analysis was performed to evaluate the influence of preoperative aneurysm diameter and target vessel angulation on the outcome during follow-up.Two hundred ninety-five target visceral vessels (TVVs) in 91 patients were considered suitable for cannulation. Technical success was 96.9% (286/295 TVVs). The median follow-up was 32.5 months (interquartile range, 14.2-50.1 months). Twelve type III endoleaks from directional branches were detected (4.2%; 5 bridging stent graft fractures and 7 disconnections). Five type III endoleaks involved the celiac trunk (one fracture and four disconnections), five the superior mesenteric artery (four fractures and one disconnection), and two the renal arteries (both disconnections). The median time to type III endoleak was 22.2 months (interquartile range, 10.9-37.6 months). Preoperative TAAA diameter (P = .028), preoperative TVV angulation (P = .037), the use of a BeGraft stent graft as bridging stent graft (P = .001), and different stent types on the same vessel (P = .048) were associated with type III endoleak at univariable analysis. Using a BeGraft stent graft (P = .010) was the only significant factor predisposing to type III endoleak at multiple logistic regression. The Cox regression analysis showed a two-fold increased risk for type III endoleak for every 10-mm increase in preoperative TAAA diameter (hazard ratio, 2.00; 95% confidence interval, 1.08-3.72; P = .028) and a 1.5 increased risk every 12° increase of preoperative TVV angulation (hazard ratio, 1.47; 95% confidence interval, 1.02-2.10; P = .037).Type III endoleaks from directional branches are a non-negligible complication after branched endovascular repair, with a relevant incidence. They tended to be clustered on specific patients, and aneurysm diameter and TVV angulation are strictly associated with the outcome. Different stent types on the same vessel should be avoided whenever possible. An intensified follow-up should be adopted for patients with large aneurysms, implanted with first-generation BeGraft, or who have been already diagnosed with type III endoleaks.

The objective of this study was to assess the primary endpoint defined as the detection of micro-embolic signals (MES) by the use of transcranial Doppler (TCD) in patients with asymptomatic carotid stenosis (≥70%) scheduled for carotid endarterectomy. The secondary endpoint consisted of testing the association of MES with stenosis severity, histopathological, and ultrasound characteristics.This was a single-center, single-arm, prospective, observational trial. Computed tomography angiography and ultrasound assessment (Geroulakos classification) were mandatory as well as being under best medical therapy. MES number and characteristics were investigated in Holter mode TCD-X device with a standard 1.5 MHz probe. The time points of evaluation were: 24 hours preoperative, 24 hours postoperative, and 30 days postoperative. The histopathological analysis was performed according to the modified American Heart Association classification. One-way analysis of variance tested MES differences over time. Univariable and multivariable logistic regression tested variables potentially associated with MES.A total of 120 patients demonstrated a significant reduction of the mean number of MES (3.35 ± 10.04 and 0.82 ± 2.39; pre- and post-carotid endarterectomy, respectively), becoming undetectable at 30 days (P = .001). Hypoechogenic plaques assessed by ultrasound were a significant risk factor for MES (P = .001). The features of plaque vulnerability, such as hemorrhagic component (P = .011), neovascularization (P = .025), signs of inflammation (P = .027), and rupture of the fibrous cap (P = .002) were predictors of MES. Cap rupture was the only predictor in the multivariate analysis (odds ratio, 5.98; P = .030). The stenosis severity was not associated with MES (P = .95) CONCLUSIONS: Patients under best medical therapy had a preoperative embolic activity becoming no more detectable after surgery. Both ultrasound and histologic markers of vulnerability were predictors of MES, and stenosis severity was not associated. TCD gives better insight into the real embolic risk, and future studies should evaluate clinical results coming from its implementation with standard imaging techniques.gov registration number NCT05134493.

Introduction: The aim of this study was to present the short-term and 2-year outcomes after use of the Bentley BeGraft as bridging stent-graft (BSG) for reno-visceral target vessel (TV) during fenestrated endovascular aortic repair (FEVAR) from a contemporary multicentric experience. Methods: A retrospective review of all consecutive patients who underwent elective FEVAR at 7 institutions located in Italy from 2015 to 2021 was performed. The main outcomes of interest for this study were technical success and TV instability, defined in accordance with current reporting standards. Patients’ survival was also assessed. Results: Overall, 81 patients received elective FEVAR during the study period. Mean age of patients was 78 years, and 89% were men. Most patients were treated for a juxta-pararenal abdominal aortic aneurysm (AAA) (68%), and 23% had already received an infrarenal aortic reconstruction. Most endografts had 3-vessel or 4-vessel design (27% and 55%, respectively), and a Cook endograft was used in 73% of cases. Overall, 266 Bentley BeGraft were implanted, of which 44 (16.5%) in the celiac trunk, 69 (26%) in the superior mesenteric artery, 79 (29.5%) in the right renal artery, and 74 (28%) in the left renal artery. Technical success was 94%, with 5 instances of technical failure that were recorded and required an additional intraoperative procedure. The early mortality rate was 4%, and acute kidney injury occurred in 14 cases with 1 requiring definitive hemodialysis. Survival at 6, 12, and 24 months in the overall cohort was 98.8%, 95.3%, and 83.4%, respectively. Freedom from TV instability at 6, 12, and 24 months in the overall cohort was 98.4%, 97.9%, and 97.2%, respectively. Events of TV instability included 3 cases of type 1C endoleak and 3 cases of type 3C endoleak, while no events of BSG fracture or thrombosis were noted. Five out of 6 cases of TV instability occurred in renal arteries, and they were all successfully treated by endovascular means. Conclusions: The data from this multicentric study show favorable short-term and 2-year outcomes of the Bentley BeGraft as BSG for reno-visceral TV during FEVAR, with low rates of TV-related endoleak and no stent occlusion up to 2 years. Clinical Impact The data from this multicentric study show satsfactory outcomes up to two years of follow-up for the Bentley BeGraft when used for brdiging reno-visceral vessels during fenestrated endovascular aortic repair. Further research will be needed to identify predictors of stent-related reinterventions and ascertain the long-term durability.

Objectives: To evaluate the feasibility of a standardized single-renal scallop stent-graft. Design: Preclinical, single-center, real-world, all-comers, retrospective cohort study. Methods: A total of 1347 abdominal aortic aneurysm (AAA) repairs (endovascular and open) performed between 2010 and 2020 were screened for elective treatment and retrievable preoperative high-quality computed tomography angiography (CTA) performed Results: Of the total, 24.7% (n=135) was feasible with prototype #10. The study versus control group sealing zones were shorter (p=0.008), with a smaller surface (p=0.009) and a higher alpha angle (p=0.039). The length and surface area increased by about 25% and 23%, respectively, (both pConclusions: The use of single-renal scalloped stent-graft might be feasible in a considerable number of AAA patients. The breakthrough stands in treating hostile AAAs presenting in mismatched renal arteries, keeping the complexity of the repair as similar as possible to standard endovascular repair with a remarkable improvement in sealing. Clinical Impact The anatomic feasibility of a single renal stent graft for the treatment of “hostile” abdominal aortic aneurysm (AAA) with mismatched renal arteries was evaluated. The experimental device could be feasible in a considerable number of patients with AAA, approaching 25%, and demonstrate significant improvements in sealing. As far as we know, this is the first paper to report the prevalence of mismatched renal arteries in a large cohort of AAA patients in the real world, while proposing a dedicated device. The breakthrough is to keep the complexity of the repair as close as possible to standard endovascular repair

Purpose: To analyze the learning curve for thoracic endovascular aortic repair (TEVAR) in a single center over a period of 25 years. Materials and Methods: In total, 390 consecutive standard TEVAR procedures undertaken between 1996 and 2021 were included in a retrospective, observational, single-center study. Cumulative sum charts were elaborated for the entire center experience (primary outcome) as well as for the first and second implanting physicians. Data on procedural variables (contrast volume, operative and fluoroscopy time), 30-day major adverse events (MAEs) and clinical success, and endoleak and reintervention rates were secondary outcomes and subdivided into 4 quartiles of experience (Q1–Q4) or presented as first 2 versus latest 2 quartiles (Q1–Q2 vs Q3–Q4). Results: The mean follow-up was 4.3±4.0 years. The center’s learning curve was achieved after 75 procedures, and it was similar for the first implanting physician. The surgeon coming thereafter had a significantly shorter curve (10 TEVARs). Comparing Q1–Q2 with Q3–Q4, 30-day MAEs (16.1 vs 11.3%, p=0.164), 30-day mortality (11.4% vs 3.6%, p=0.003), and intraoperative additional maneuvers (21.5% vs 13.3%, p=0.033) were reduced along with an improvement in clinical success (85.9% vs 90.3%, p=0.190). From Q1 to Q4, operative time (139.8±65.5 to 76.7±43.7 min, p=0.001), fluoroscopy time (15.1±8.8 to 7.1±5.1 min, pConclusion: The learning curve shortened significantly over time with non-negligible clinical outcome improvements, suggesting that specific endovascular training is mandatory to become an effective TEVAR performer. Clinical Impact For the first time in literature, the standard TEVAR’s learning curve has been evaluated at a single vascular surgery center over a period of 25 years. The learning curve for the center and the first physician historically undertaking TEVAR was achieved at the 75th treated patient. The learning curve of the surgeons coming thereafter was significantly shorter (10 cases). This quarter-century demonstrated that intraoperative learning-related variables were associated with long-term clinical outcomes and all have improved over time. Centers approaching TEVAR for the first time and training program providers could use these data to aim to offer better clinical outcomes.

Background/aim: Clinical outcomes of celiac artery (CA) coverage during aortic procedures are often contradicting and the fate of this additional maneuver is still unclear. This study summarizes the results of available literature and aims to clarify the impact of CA coverage during thoracic endovascular aneurysm repair (TEVAR) in patients with inadequate distal sealing zone. Methods: Prospective and retrospective, observational original articles focused on CA coverage during elective/urgent TEVAR for descending thoracic aortic pathology (DTAP) were included. PubMed/MEDLINE, Embase, and Cochrane Central Register of Controlled Trials database were examined to identify articles published from January 2007 to December 2020, according to PRISMA guidelines. Early and late visceral (any sign or symptom reported) and neurological (both transient and permanent) complications were considered as primary outcomes. Onset of any endoleak, type IB endoleak, need of reintervention, and TEVAR-related mortality were considered as secondary outcomes. Results: A total of 5618 articles were extracted for analysis and 13 studies were finally included in the synthesis. A total of 178 CAs were covered during 2653 TEVAR (7%). Spinal cord ischemia was 8% (95% CI, 5–14%, I2 0%) Any endoleak and type IB endoleak was observed in 12% (95% CI, 6–21%, I2 17%) and 5% (95% CI, 2–11%, I2 0%), respectively. Thoracic endovascular aneurysm repair-related reoperation was necessary in 8% (95% CI, 4–14%, I2 0%), the majority of which (14/18, 78%) performed for distal sealing failure; mortality rate was 9% (95% CI, 5–14%, I2 0%). Out of 178 patients, 168 (94%) were available for follow-up, ranged 12 to 42 months. Visceral complications, any endoleak, and type IB endoleak were identified in 15% (95% CI, 10–23%, I2 45%), 20% (95% CI, 13–29%, I2 8%), and 8% (95% CI, 4–15%, I2 0%), respectively. Thoracic endovascular aneurysm repair-related reintervention was required in 8% (95% CI, 4–14%, I2 0%). Mortality rate was 17% (95% CI, 12–25%, I2 4%). Conclusions: Celiac artery coverage in DTAP should be regarded as a “bailout” procedure especially in urgent/emergent settings but requires caution in elective cases. Even if transient visceral ischemia is frequent, life-threatening complications are rare. Early and late mortality rates are similar to standard TEVAR although the risk of type IB endoleak and reintervention may be an issue.

AIMS To investigate the clinical performance of regenerative periodontal surgery in the treatment of furcation defects versus open flap debridement (OFD) and to compare different regenerative modalities. MATERIAL AND METHODS A systematic search was conducted to identify RCTs evaluating regenerative surgical treatment of furcations with a minimum of 12-month follow-up. Three authors independently reviewed, selected and extracted data from the search conducted and assessed risk of bias. Primary outcomes were tooth loss, furcation improvement (closure/conversion) (FImp), gain of horizontal bone level (HBL) and attachment level (HCAL). Secondary outcomes were gain in vertical attachment level (VCAL), probing pocket depth (PPD) reduction, PROMs and adverse events. Data were summarized into Bayesian standard and network meta-analysis in order to estimate direct and indirect treatment effects and to establish a ranking of treatments. RESULTS The search identified 19 articles, reporting on 20 RCTs (19 on class II, 1 on class III furcations) with a total of 575 patients/787 defects. Tooth loss was not reported. Furcation closure ranged between 0% and 60% (10 trials), and class I conversion from 29% to 100% (six trials). Regenerative techniques were superior to OFD for FImp (OR = 20.9; 90% CrI = 5.81, 69.41), HCAL gain (1.6 mm), VCAL gain (1.3 mm) and PPD reduction (1.3 mm). Bone replacement grafts (BRG) resulted in the highest probability (Pr = 61%) of being the best treatment for HBL gain. Non-resorbable membranes + BRG ranked as the best treatment for VCAL gain (Pr = 75%) and PPD reduction (Pr = 56%). CONCLUSIONS Regenerative surgery of class II furcations is superior to OFD. FImp (furcation closure or class I conversion) can be expected for the majority of defects. Treatment modalities involving BRG are associated with higher performance.

Objective: The aim of this study was to evaluate aortic remodelling and associated complications in patients treated by thoracic endovascular aneurysm repair (TEVAR) for blunt traumatic aortic injuries (BTAI). Methods: This was a retrospective, observational, multicentre study. Remodelling was considered as aortic diameter variations of >2 mm and distal graft and aortic axis angle modification measured by computed tomography angiography (CTA). The predefined levels of measurement were the proximal end of the graft (D1: landing in zone [LZ] 2; D2: LZ 3); distal end (D3); and control measurement (D4) 15 mm beyond D3. Survival, procedure, graft, and/or radiation exposure related complications were registered. CTA was required within three months and at one, six, and 10 years post-operatively. Results: Between 2004 and 2017 52 patients were treated; 47 were included for remodelling analysis (five immediate deaths were excluded); median age was 47 years (range 20–80 years). Mean TEVAR oversizing was 19.6% ± 9.7% (range 5%–35%). Following a median follow up of 67.4 ± 56.1 months (range 14–153 months) survival at one, three, six, and 10 years was 90.4% (standard error [SE] 4.1%), 88.3% (SE 4.5%) 84.8% (SE 5.5%), and 84.8% (SE 5.5%), respectively. There were no procedure/graft related complications except for one late intramural haematoma that required re-intervention. Freedom from aortic remodelling at one, six, and 10 years was 85.1% (SE 5.2%), 30.9% (SE 8.6%), and 24.7% (SE 8.8%), respectively. The increase in D1/D2 and D3 diameters were influenced by time from intervention (both p

Endovascular repair of aortic arch lesions requires revascularization of epiaortic vessels in case of coverage. The objective of this study was to compare the outcomes of surgical bypass versus endovascular reconstruction with a chimney graft.A retrospective analysis of a multicenter register between January 2005 and December 2019 was performed. A total of 127 patients were included and divided into 2 groups: thoracic endovascular aortic repair + surgical debranching (n = 72) and thoracic endovascular aortic repair + chimney stenting (n = 55). The main end points were major neurologic sequelae and type IA endoleak. Propensity score matching was performed to analyse baseline variables related to these outcomes.The mean follow-up was 35.6 months for the debranching group and 34.1 for the chimney group (P = 0.65). The incidence of stroke was higher in the chimney group although not statistically significant (7.3% vs. 4.1%; P = 0.46); for both groups, a wide angle between the ostium of the target vessel and the aorta and landing in Ishimaru Zone 0 was found to be the main predictors for major neurologic sequelae (P = 0.002 and P = 0.003, respectively). During follow-up, 9 (12.5%) type IA endoleaks occurred in the debranching group and 12 (21.8%) in the chimney group (P = 0.14). Aortic diameter larger than 66 mm and arch angle46° had a strong association with proximal endoleak incidence (P = 0.001 and P = 0.011, respectively) CONCLUSIONS: Surgical debranching showed better results than chimney stenting in terms of major neurologic events incidence and type IA endoleak, although the difference between the groups was not statistically significant. Further research with larger cohorts is needed to establish the indications for these procedures.

Objective Target vessel instability is a relevant complication after thoracoabdominal aortic aneurysms branched endovascular aortic repair (BEVAR). Long-term bridging stent-graft (BSG) durability has already been established, but the incidence of long-term complications as component fractures was not deeply investigated. This paper aims to assess BSG fracture incidence and risk factors after BEVAR. Methods This was a dual-center observational retrospective cohort study. Data of each patient treated with BEVAR between April 2008 and December 2019 were prospectively collected. The primary outcome was the incidence of BSG fracture during follow-up. A logistic regression analysis was performed, including preoperative and postoperative measurements as well as intraoperative details to identify potential risk factors. Results Two hundred ninety-five target visceral vessels in 91 patients were considered suitable for cannulation. Technical success was 96.9% (286/295 target visceral vessels). The median follow-up was 32.5 months (interquartile range, 14.3-50.1 months). Five BSG fractures (1.75%; 5/286) were detected. Four BSG fractures involved the superior mesenteric artery, and one the celiac trunk. Four different types of fractured stents were detected during follow-up: two Advanta, one BeGraft, one Fluency, and one Viabahn. The median time to BSG fracture was 28.2 months (interquartile range, 11.7-50.8 months). The use of multiple stents (P = .030) and different stent types on the same vessel (P = .004) were associated with BSG fracture at univariable analysis. Using bare-metal stents for distal relining (P = .045) was the only significant factor predisposing to BSG fracture at multiple logistic regression. Conclusions BSG fracture is a rare but severe complication after BEVAR. It is not related to the stent type used as bridging stent, and it is hardly predictable based on preoperative anatomy. Using multiple and different stents on the same vessel and relining the bridging stents with bare-metal stents may increase BSG fracture risk. A strict computed tomography angiography follow-up remains the best strategy to detect target vessel instability.

Purpose To evaluate the Covera Plus (Bard, Tempe, Arizona) covered stent as a bridging stent in branched thoraco-abdominal endovascular aneurysm repair (BEVAR). Materials and Methods Retrospective analysis of 112 self-expandable stents was performed at 2 university centers between August 2017 and March 2019. Thirty-one consecutive BEVAR procedures were studied (21 males; mean age, 75 years; 29 American Society of Anesthesiologists grade III/IV) with 119 patent target vessels (7 did not receive the studied device). Primary endpoints were technical success, branch instability, and primary/secondary clinical success. Secondary endpoints included primary/secondary patency and any adverse events. Results Technical success was 100%. Median follow-up was 12 months (interquartile range, 6–14 months). Branch instability was registered twice (2/112), due to immediate renal occlusion and type Ic endoleak; no additional events occurred during the follow-up. Primary clinical success was 84%. There were 2 immediate deaths, 1 upper limb ischemia, 1 hemorrhage from splenic artery, and 1 type Ic endoleak; these last 3 events were successfully treated, with a secondary clinical success of 100% that was maintained during the follow-up. One late death occurred. Primary patency was 99% (111/112) and 100% (105/105) within 30 days and at the end of the study period,respectively. Adverse events included 4 acute kidney injuries and 2 spinal cord ischemia. No type I/III endoleaks, occlusion, fracture, or dislodging were diagnosed after 30 days. Conclusions The stent graft seems safe and effective for bridging in BEVAR with low branch instability and high patency rate. Longer follow-up is required to confirm these promising results.

The aim of this study is to compare early and follow-up outcomes of late open conversions (LOC, with complete or partial endograft explantation) and semi-conversions (SC, with endograft preservation) after endovascular aneurysm repair in a multicenter experience.All LOC and SC performed from 1997 to 2020 in 11 vascular centers were compared. Endograft infections or thrombosis were excluded. Primary endpoints were early mortality and long-term survival estimates. Secondary endpoints were differences in postoperative complication rates and conversion-related complications during follow-up.In the considered period, 347 patients underwent surgery for endovascular aneurysm repair complications. Among these, 270 were operated on for endoleaks (222 LOC, 48 SC). The two groups were homogeneous in terms of American Society of Anesthesiologists score (LOC, 3.2 ± 0.7; SC, 3 ± 0.5; P = .128) and main endograft characteristics (suprarenal fixation, bifurcated/aorto-uni-iliac configuration). The mean age was 75 ± 8 years for LOC and 79 ± 7 years for SC (P = .009). Reasons for LOC were: 62.2% (138/222) type I endoleak, 21.6% (48/222) type II endoleak, 7.7% (17/222) type III endoleak, and 8.5% (19/222) endotension. Indications for SC were: 64.6% (31/48) type II endoleak, 33.3% (16/48) type I endoleak, and 2.1% (1/48) type III endoleak. Thirty-day mortality was 12.2% (27/222) in the LOC group, and 10.4% (5/48) in the SC group (P = .73). Postoperative complication rate was higher in the LOC group (45.5% vs 29.2%; P = .04). The estimated survival rate after LOC was 80% at 1 year and 64% at 5 years; after SC, it was 72% at 1 year and 37% at 5 years (log-rank P = .01). During the median follow-up of 21.5 months (interquartile range, 2.4-61 months), an endoleak after SC was found in the 38.3% of the cases; sac growth was recorded in the 27.7% of SC patients.SC has an early benefit over LOC in terms of reduced postoperative complications but has a significantly inferior mid-term survival. The high rates of persistent and/or recurrent endoleaks reduce SC durability.

Background The diabetic foot ulcer (DFU) is a high prevalence complication that significantly impairs the health-related quality of life (HRQoL) and is characterized by prolonged hospital length of stay (LOS). The impact of the micro-fragmented autologous adipose tissue injection at the minor amputation wound in the case of DFU (MiFrAADiF) on HRQoL and LOS compared to the standard care has not been determined yet. Methods This was a two-arm, 6-month, individually randomized controlled single-center clinical trial. A 1:1 randomization to local injection of autologous micro-fragmented adipose tissue (treatment group; n=57) or standard clinical care (control group; n=57) was performed. The primary objective was the HRQoL. The secondary endpoint was the LOS. HRQoL was assessed with the Medical Outcomes Study 36-item Short-Form Health Survey which provides 2 scores focused on physical (PCS) and mental functioning (MCS). The trial was registered in ClinicalTrials.gov (NCT03276312). Results The type of treatment (p=0.009) and the time elapsed since surgery (p= 0.0000) demonstrated a significant improvement on PCS. The MCS improvements resulted in a non-significant association with treatment (p= 0.21). The time elapsed since surgery showed a significant influence on the MCS (p= 0.0000). The mean LOS was 16.2 days and 24.4 days for the treatment and the control group respectively (p= 0.025). Conclusions The MiFrAADiF trial demonstrated a significant improvement in terms of physical HRQoL and a significant reduction of the hospital length of stay after injection of micro-fragmented autologous adipose tissue in diabetic patients' minor amputations wound.

Purpose: To define the learning curve of a widely employed stent-graft for thoracic endovascular repair (TEVAR) by analyzing procedural variables and their impact on long-term outcomes. Materials and Methods: Standard TEVARs for each major aortic thoracic disease were included excluding procedures using thoracoabdominal, arch fenestrated/branched devices and/or chimneys. The primary outcome was the learning curve analysis using the cumulative sum chart method. The secondary outcomes, presented as early (Q1–Q2) versus latest (Q3–Q4) quartiles of experience, were 30-day major adverse events (MAEs); procedural details (additional maneuvers, operative and fluoroscopy time, and contrast volume); 30-day clinical success; endoleak; aorta-related reintervention; and overall and aorta-related survival. Results: Between November 2005 and September 2021, 220 consecutive TEVAR procedures involving the Relay endograft (Terumo Aortic, Sunrise, FL, USA) were performed and included in the present analysis. The mean follow-up was 4.5 ± 3.9 years. The learning curve was reached after 10 patients. Secondary outcomes improved significantly over experience. Thirty-day MAE occurrence was 14.5% versus 11.8% (p=0.550). Additional maneuvers (p=0.009), access-vessel additional maneuvers (p=0.010), operative time (p=0.004), Relay Plus (p=0.001), and implantation of multiple stent-grafts (p=0.034) were independent risk markers for MAEs. Operative time (125.9 ± 66.7 vs 86.7 ± 48.5 minutes, pConclusion: In a high-volume center with a consistent previous endovascular experience, the Relay graft presented satisfactory long-term results with a short learning curve supporting its reliability. Clinical Impact The manuscript addresses the understanding of how many TEVAR procedures with a currently implanted device have been required to reach the learning curve for an endovascular skilled center. Our TEVAR experience with the Relay stent-graft (Terumo Aortic) demonstrated that ten implantations were required to achieve the device-related learning curve. The fifteen-year analyzed period showed that intraoperative learning-related variables were associated with long-term clinical outcomes and both improved over time. The Relay stent-graft presented satisfactory long-term results along with a short learning curve in a high-volume endovascular center supporting its ongoing implantation.

Intraoral ultrasonography has been widely employed for the preoperative assessment of tumor margins due to its capability to evaluate depth of invasion (DOI) and tumor thickness (TT). Recently, a novel ultrasonographic technique, ultra-high frequency ultrasound (UHFUS) has been increasingly applied to the study of oral lesions. This study evaluates the potential application of intraoral UHFUS to assess DOI and TT parameters of oral squamous cell carcinoma (OSCC) lesions. Patients clinically suspected of OSCC lesions were enrolled and underwent an intraoral UHFUS examination preoperatively. The parameters of TT, DOI, echogenicity, and vascularization were assessed. The parameters of TT and DOI as evaluated by means of UHFUS were compared to histology, which was set as the benchmark. Ten patients in total were enrolled. UHFUS-based DOI and TT measurements were found to positively correlate with histology (p &lt, 0.05), although UHFUS provided a slight overestimation of DOI. No differences were found in terms of echogenicity or vascularization depending on the site of the lesion. According to these preliminary results, UHFUS could support the preoperative assessment of TT and DOI, potentially enhancing the clinical evaluation of OSCC.

Objective At our institution, we adopted routinely ultrasound guided approach for all percutaneous procedures. The objective of this study was to describe the predictors of access site failures (ASFs) in patients undergoing percutaneous aorto iliac revascularization and to also evaluate whether other factors such as time period or different vascular devices may influence outcomes in terms of ASFs. Methods We reviewed all consecutive percutaneous revascularizations performed for aortoiliac occlusion or stenosis at our institution from 2011 to 2020. All procedure were performed using an ultrasound (US) guided common femoral access. The primary outcome was ASFs, defined as bleeding or groin hematomas that required transfusions; pseduoaneurysm (diagnosed by US); retroperitoneal hematoma; artery laceration or ruptured (diagnosed intraoperatively); and thrombosis. Multivariable logistic regression was used to determine predictors of ASFs. Results A total of 502 femoral arteries were accessed under DUS guidance with no failure in sheath placement. Technical success was achieved in 498 of 502 procedures (99.2%). ASFs occurred in 21 patients (7%); but year of procedure appear to be associated with an excess of ASFs as rates were different between the first and second period of the study (10.9% vs 4.8%, P = .04). Results of multivariable logistic regression model indicated that independent predictors of ASFs were common femoral artery (CFA) calcification peripheral artery calcium scoring system (PACCS) grade (odds ratio [OR], 8.7; 95% confidence interval [CI], 5.5-13.7), and CFA diameter (OR, 0.46; 95% CI, 0.25-0.85). Compared to patients with successful percutaneous access, ASFs resulted in longer post-op lengths of stay (P = Conclusion Percutaneous US guided access can be safely performed in patients undergoing endovascular procedures for aorto iliac revascularization with TASC C and D lesions. CFA calcification PACCS grade greater than 3 and smaller femoral vessel diameter are independent risk factors for ASFs.

A 78-year-old woman presented with type IIIC and IIID endoleaks after endovascular treatment for a thoracoabdominal aortic aneurysm. Mating between the ruptured segments of superior mesenteric artery stent graft was performed. After failed attempts at relining the right renal artery stent graft, a hybrid approach was used to connect the side branch to the target vessel: a stent graft was deployed into the side branch of the main graft and it was temporarily occluded with a balloon. After opening the sac, a stent graft was deployed into the right renal artery and the two stent grafts were connected with a running suture. Follow-up examination performed 1 month postoperatively by computed tomography imaging confirmed the effectiveness of this treatment.

AIM An acute phase response is induced after non-surgical periodontal treatment (SRP). The main aim of this study was to compare acute phase (24-hr) and medium-term (3-months) inflammation and clinical outcomes after SRP with or without application of enamel matrix derivative (EMD) in sites with probing pocket depth (PPD) ≥ 6 mm. METHODS Thirty-eight periodontitis-affected subjects were randomized to SRP or SRP + EMD. Periodontal parameters were recorded at baseline and 3 months. Serum samples were collected at baseline, 1 and 90 days after treatment. RESULTS Both treatments triggered an intense acute inflammation on day 1, which regressed to baseline values at 3 months. D-dimer and cystatin C levels did not show sharp increases in SRP + EMD group 24 hr after treatment, compared to SRP. Significant difference between groups was observed for D-dimer (p

Purpose: To report preliminary outcomes of Viabahn Balloon-Expandable Endoprosthesis (VBX) stent-graft as bridging stent for renal arteries in fenestrated endovascular aneurysm repair (FEVAR). Materials and Methods: Between 2018 and 2019, patients undergoing FEVAR at 3 referral Italian university hospitals were prospectively collected. During the study period, VBX was the first-line choice as bridging stent for renal arteries. Procedural and anatomical data were analyzed, including renal artery (RA) configuration. A dedicated software (3Mensio, Vascular Imaging, Bilthoeven, The Netherlands) was used and RA anatomy classified as follow: upward-oriented in case of any angle >30° above the horizontal or transverse axis perpendicular to the aortic axis, downward-oriented if there was an angle >30° measured below the transverse axis and downward + upward in case of an angle 90°. Primary endpoints were technical success, defined as complete deployment of the fenestrated endograft without target vessel (TV) loss, limb stenosis or occlusion and type I or III endoleak, and freedom from target artery instability (TAI), defined by target vessel-related death, occlusion, rupture or reintervention for stenosis, endoleak or disconnection. Secondary endpoints were target artery patency rate and freedom from reinterventions. Results: A total of 26 elective FEVAR for juxta/pararenal aneurysm (20), thoracoabdominal type II (3) and type IV (3) were included. Fifty-one RA were planned for revascularization. Of these, 32 were downward, 10 horizontal, 6 upward, 4 were downward + upward. Technical success was achieved in 88.5% (23/26) of patients and 94.2% (48/51) of the TVs. One occlusion (2.1%) occurred within 30 days in a patient with previous endovascular aortic repair and suprarenal fixation. During follow-up (median 10 months), there was 1 type IC endoleak after 6 months (2.1%) in a patient with upward plus downward arterial orientation. Freedom from TAI was 96.1% (CI = 0.89 to 1.04) at first month and 92.3% (CI = 0.82 to 1.03) at 6 months. No aneurysm-related mortality and renal insufficiency occurred during follow-up. Conclusion: The use of VBX as bridging stent of RA in FEVAR is safe and feasible. Previous EVAR and tortuosity of RA may be a challenging on target vessel fate.

Aim : To describe a bailout technique to advance and precisely deploy thoracic endograft in the ascending aorta in case of difficulty crossing the aortic arch. Case Report : A 73-year-old man presented with a large ruptured aneurysms in the descending aorta. During the TEVAR, stent-graft passage through the aortic arch was impossible due to the severe tortuosity of the aorta. The problem has been resolved using the sheath-anchoring rail guidewire (SARG) technique. Through an axillary access, a snare was used to capture the stiff wire from the femoral access. A sheath was advanced over the stiff wire to the ascending aorta and placed there. By exploiting the grip of the sheath on the stiff in the ascending aorta, it was possible to handle the tension, move the delivery system through the arch and carefully deploy the graft. Conclusions : The SARG is a simple and quick learning technique which can be useful for Physicians dealing with complex aortic arch anatomy.
