Article Synopsis
  • The Delphi consensus aimed to clarify management practices for abdominal aortic aneurysms (AAAs) due to conflicting data in previous literature.
  • A group of 44 experts anonymously discussed six key topics over three rounds, achieving a 100% response rate.
  • Key findings included the agreement on minimum case volume for AAA repairs, the effectiveness of screening programs, lifelong surveillance after repair, and the consideration of screening for women smokers at 65, but no consensus on certain repair thresholds or thrombosis prevention was reached.

Calcification represent one the most important predictors of treatment failure of endovascular therapy for peripheral arterial disease, since it restricts wall expansion and acts as a barrier for drug uptake. It also increases complications after PTA like dissection, perforation, and embolization with poor outcomes. Intravascular lithotripsy (IVL) is a novel approach for the treatment of vascular calcifications with the goal to optimize outcome in patients with PAD and heavy calcifications.

The standard of care for treating symptomatic peripheral arterial disease has been percutaneous transluminal angioplasty with or without stenting over the last couple of years. This endovascular treatment of claudicants or patients with critical limb ischemia has increased in numbers and has even surpassed open surgery. Our daily practice has evolved to an endovascular-first approach, especially in the femoropopliteal region, being the most frequently treated vessel.

Aims:: Stenting of the popliteal artery (PA) is generally considered inappropriate due to the high mechanical stress and bending of the artery during knee flexion. Nevertheless, vessel recoil remains problematic following angioplasty procedure for chronic total occlusions (CTOs) and adjunctive stenting may be required. The purpose of this study is to compare balloon angioplasty alone versus bailout stenting for isolated CTO of the PA.

Background: The iliac side branch device (IBD) is a valid method for the treatment of abdominal aorto-iliac aneurysms. However there is still a lack of evidence regarding the optimal length of the bridging stent graft (BSG) since aneurysmal degeneration of the hypogastric artery (HA) is an exclusion criterion. The aim of this study was to analyse the impact of longer BSG compared to the widely used 38mm stent-grafts in terms of reintervention rate and primary patency.
