AVF Webinar: Patient Selection for Iliac Vein Stenting

Selecting the Right Patient for Iliac Vein Stenting

Appropriateness rests on patient, pathology, and doctor selection: standing exams and hydration status avoid false positive lesions, intent-to-treat is favored over staged studies, isolated C2 disease should never be stented, and expectations differ for pain, ulcers, and swelling given migration risks.

Imaging Pitfalls and a Diagnostic Algorithm for Combined Disease

Dehydration and position skew CTV and MRV toward false positives and negatives; a SIR based algorithm and cases like a pancake iliac vein and duplicated IVC illustrate pitfalls, alongside a sequencing algorithm pairing ablation with iliac stenting in mixed reflux and obstruction.

IVUS-Guided Stent Sizing and Landing Zone Technique

Dedicated venous stents are sized from IVUS reference diameter, respecting the common to external iliac curvature when choosing landing zones, with debate over stent length and protecting the confluence while still covering the full lesion.

Why Stents Fail: ABRE Trial Analysis and a DVT Case

Failure analysis of ABRE occlusions found missed common femoral disease, inadequate inflow, technical errors, and anticoagulation cessation as leading causes, closing with an iliofemoral DVT case treated with thrombectomy and IVUS-guided stenting.
