The aim of this study was to compare the 2-year outcomes of de novo versus postendovascular lesion treatment of femoropopliteal occlusions included in a national, multicenter, observational, prospective registry based on the treatment of critical Limb-threatening IschaeMia with infragenicular Bypass adopting in situ SAphenous VEin technique (LIMBSAVE) registry.From January 2018 to December 2019, 541 patients from 43 centers have been enrolled in the LIMBSAVE registry. Of these patients, 460 were included in the present study: 341 (74.1%) with de novo lesions (DN group) and 119 (25.9%) with postendovascular treatment lesions (PE group). Initial outcome measures were assessed at 30 days after treatment. Furthermore, at the 2-year follow-up, the estimated outcomes of primary patency, primary-assisted patency, secondary patency, and limb salvage were analyzed with Kaplan-Meier curves and compared between groups with the log-rank test.Both groups were homogeneous in terms of demographic data, preoperative risk factors, and clinical presentation. However, compared with DN group, more patients in PE group had a great saphenous vein diameter of less than 3 mm (11.1% vs 21%; P = .007). Intraoperatively, both groups showed similar distal anastomosis sites: below-the-knee popliteal artery (63% DN group, 66.4% PE group) and tibial vessel (37% DN group, 33.6% PE group) (P = .3). The overall mean duration of follow-up was 11.6 months (range, 1-24 months). At the 2-year follow-up, there were no differences between the two groups in terms of primary patency (66.3% DN group vs 74.1% PE group; P = .9), primary-assisted patency (78.2% DN group vs 79.5% PE group; P = .2), secondary patency (85.1% DN group vs 91.4% PE group; P = .2), and limb salvage (95.2% DN group vs 95.1% PE group; P = .9).The LIMBSAVE registry did not show a worsening of overall patency and limb salvages rates at the 2-year follow-up in patients undergoing in situ saphenous bypass after a failed endovascular approach for long femoropopliteal occlusive disease. This finding is in contrast with what has been published in literature.

The aim was to demonstrate contemporary outcomes of in situ saphenous vein bypass using a valvulotome.Analysis of two year outcomes of a multicentre registry based on the treatment of critical Limb Ischaemia with infragenicular Bypass adopting in situ SAphenous VEin technique (LIMBSAVE). Between January 2018 and December 2019, 541 patients in 43 centres were enrolled. In all patients an innovative valvulotome was used. Early outcomes were assessed. Two year outcomes according to Kaplan-Meier curves in terms of patency and limb salvage were evaluated. Associations between patient and procedure variables were analysed with univariable and multivariable analyses.In all cases, a valvulotome was able to lyse the valves. Vein injury due to the in situ technique was 3.5%. Thirty day mortality and major amputation rates were 3% and 0.9%, respectively. Mean follow up was 12.1 months. Two year estimated primary patency, primary assisted patency, secondary patency, and limb salvage were 69.1%, 81.4%, 86.5%, and 94.5%, respectively. Multivariable analysis showed an association between pre-operative vein diameter3 mm and lower primary patency (hazard ration [HR] 14.3, p.001), primary assisted patency (HR 9.4, p = .002), secondary patency (HR 7.2, p = .007), and limb salvage (HR 7.8, p = .005) rates. Distal anastomosis to a tibial or foot vessel was also associated with lower primary patency (HR 4.8, p = .033), and primary assisted patency (HR 6, p = .011) rates. Use of a suprafascial tributary collateral as a graft was associated with lower primary patency (HR 6.7, p = .013), and primary assisted patency (HR 4.2, p = .042) rates.Vein diameter3 mm, distal anastomosis on a tibial or foot vessel, and use of a suprafascial tributary collateral as a graft were significantly associated with loss of patency and limb loss during follow up.

Introduction and importance Extracranial carotid aneurysms (ECCAs) are relatively uncommon. Most of these lesions are due to atherosclerosis, trauma, infection, radiotherapy, previous surgery or iatrogenic event. Severe complications include rupture, dysphagia, respiratory symptoms and brain embolization. Case presentation We report a case of a large saccular aneurysm of the extracranial internal carotid artery (EICA) in a 83-year old asymptomatic woman without any apparent causative history. The patient underwent a successful repair of the aneurysm by aneurysmectomy and primary end-to-end anastomosis between the proximal and distal portion of the remaining vessel with continuity restored without tension. Clinical discussion ECCAs are rare with few cases reported in the most recent literature. There is little knowledge of their natural history and management. Both surgical and endovascular as well as medical treatments have been recommended depending on disease-location and comorbidities. Conclusion Although treatment should be individualized time by time by evaluating patient's characteristics, the surgical repair could be a safe and effective solution to treat distal EICAs, especially for symptomatic and true growing lesions. The presentation, the diagnostic evaluation, and the successful surgical treatment are discussed.

Introduction Percutaneous endovascular abdominal aortic aneurysm repair (PEVAR) using the Perclose ProGlide suture mediated closure device is currently performed on a global scale. A safe, effective, and cheap technique for achieving haemostasis during PEVAR is described that allows the reversible downsizing of the arteriotomy, without using any other devices. Technique The procedure consists of pulling the blue thread of the pre-implanted ProGlide, advancing the knot close to the arterial wall by pushing it with the dilator of a small introducer sheath, and maintaining the system under tension by grasping the end of the blue thread with a haemostat until bleeding control is achieved. Discussion Seventeen PEVAR femoral access downsizing procedures have been performed between February and June 2018 and no complications were observed. The technique could be useful in everyday practice and has now become the author's standard practice., Highlights • The described technique allows haemostasis to be achieved during PEVAR procedures. • The downsizing method is reversible at any time of the PEVAR procedure. • The described technique could add a useful tip to daily surgical activity.
