The Role of the Omniflow II Biosynthetic Graft in Postoperative Wound Problems After Lower Limb Revascularization: A Single Center Prospective Registry.

Objective: To investigate the role of the Omniflow II prosthesis in the prevention of vascular graft infection (VGI) in patients with peripheral arterial disease and to report on short-and mid-term graft-related morbidity.

Material And Methods: Patients were included in prospective registry between October 2019 and March 2023. The primary endpoint was to report infection-related problems, operation-related wound problems, and short- and mid-term graft-related morbidity.

The influence of narrow aortic bifurcation on limb graft patency: a two-center retrospective study.

Background: Narrow aortic bifurcation (NAB) has been considered as a potential risk factor for graft limb thrombosis after endovascular aortic repair (EVAR). The aim of this study was to compare mid- and long-term outcome of EVAR in patients with NAB and standard aortic bifurcation (SAB).

Methods: Data from patients receiving EVAR were prospectively collected and retrospectively analyzed.

Treatment of ruptured subclavian steal flow-related vertebrobasilar junction aneurysms: Case report on surgical and endovascular considerations from two cases.

Introduction: Subclavian steal phenomenon causes retrograde flow through the vertebral artery, ipsilateral to the affected subclavian artery, which rarely leads to flow-related vertebrobasilar junction (VBJ) aneurysms.

Case Descriptions: We describe two cases of subarachnoid hemorrhage from such ruptured aneurysms in which the retrograde flow direction in the vertebral artery complicated surgical and endovascular treatment.

Discussion: Reversed flow in the vertebral artery, ipsilateral to the stenotic subclavian artery leads to a lack of proximal control in surgical clipping of these VBJ aneurysms and jeopardizes stability of coil and stent placement in endovascular aneurysm treatments in this setting.

Late hematogenous seeding and infection of a femoropopliteal Omniflow II bypass.

Introduction: Omniflow II is promoted as an infection-resistant vascular graft. It is used to treat vascular graft infection; nevertheless, early graft infection has been reported.Report: A 71-year-old patient was treated with an Omniflow II bypass for a non-healing diabetic foot ulcer.

Predictive Factors of Operative Need in Medically Managed Type B Aortic Dissections.

Background: Aneurysmal degeneration of medically managed type B aortic dissection (TBAD) can be a life-threatening condition. Preventive thoracic endovascular aorta repair (TEVAR) in patients at risk could potentially be beneficial. The aim of this study was to examine the predictors for late aneurysmal dilatation after TBAD.
