Compliance of Textile Vascular Prostheses Is a Fleeting Reality.

Objective: Compliance is considered to be a major property influencing the long term performances of synthetic vascular substitutes that could play a role in anastomotic false aneurysm and intimal hyperplasia stenosis onset. Over the last decades, manufacturers have tried to develop substitutes that mechanically mimic arterial properties and avoid a compliance mismatch at the anastomoses in particular. However, data are missing about how initial compliance properties could change with time.

Non-Anastomotic Complete ePTFE Axillobifemoral Bypass Disruption and Thrombosis Following Shoulder Dislocation.

Complete disruption of an expanded polytetrafluoroethylene (ePTFE) vascular graft is rare. This is a report of a case of a 70 year old man presenting with left shoulder dislocation, which was reduced immediately. Two weeks later, the patient presented with Rutherford 2b bilateral lower limb ischaemia related to the thrombosis of an ePTFE axillobifemoral bypass.

Learning Curve of Robotic-Assisted Anastomosis: Shorter than the Laparoscopic Technique? An Educational Study.

Background: Achieving aortic anastomosis in laparoscopic surgery remains a technical challenge. The Da Vinci robot could theoretically counteract this issue by minimizing the technical challenge. The aim of this study was to compare the learning curves of performing vascular anastomoses by trainees without any experience using purely laparoscopic versus robotic-assisted techniques.

Relation between tensile tests and compliance in polyester textile vascular prostheses.

Background: Compliance is one of the mechanical features of a vascular prosthesis (VP) that influences its performances. The goal of the present in vitro study was to attempt characterizing textile VP compliance through mechanical tests proposed in the standards.

Methods: Three different models of commercially available knitted VP (P1, P2, and P3) were studied using longitudinal and circumferential traction tests on coated and uncoated samples.

Associated Da Vinci and magellan robotic systems for successful treatment of nutcracker syndrome.

Here, we report the case of a 26-year-old woman suffering from nutcracker syndrome with concurrent disabling pelvic congestion syndrome. She was given the minimally invasive treatment of left renal vein transposition with the Da Vinci(®) robotic system (Intuitive Surgical, Sunnyvale, CA), followed the next day by a gonadal vein and pelvic varicose embolization using a robotic intraluminal navigation with the Magellan™ robotic system (Hansen Medical, Mountain View, CA). The procedure was uneventful, and the patient had good results at 6 months of follow-up, including a patent left renal vein and complete relief of symptoms.

Systematic cervical approach for endovascular treatment of thoracic aortic diseases with debranching.

Endovascular treatment of thoracic aorta (TEVAR) often requires supra-aortic arterial trunks debranching to provide an acceptable proximal landing zone. To facilitate TEVAR procedures involving landing zones 1 to 3, we propose a systematic 4-step strategy with 1) a primary surgical cervical exposure of the supra-aortic trunks; 2) insertion through this access of a 5 Fr introducer in the first non-covered supra-aortic trunk to delineate precisely the landing zone; 3) followed by deployment of the thoracic endograft through one femoral access; 4) immediate completion of the surgical debranching, i.e.
