AVF Webinar: Iliofemoral Venous Stenting Techniques

Iliofemoral Stenting Fundamentals: Sizing and Selection

Presenters size stents from IVUS reference vessel diameter with modest oversizing, favor longer stents spanning the inguinal ligament to reduce migration, avoid jailing the profunda or contralateral confluence, and always decompress pelvic masses before stenting.

Managing Residual Thrombus After Thrombectomy

Layered thrombus left after mechanical thrombectomy is best treated with prolonged large diameter balloon dilation rather than restenting inside a stent, since balloons drive outcomes more than added metal; aspiration technology shows early promise for this layering.

Inflow Assessment and Crossing the Inguinal Ligament

IVUS identifies missed disease below the landing zone that venography alone misses roughly three quarters of the time, and crossing the ligament with dedicated venous stents is safe, since residual untreated disease, not stent length, drives late occlusion.

Crossing Chronic Occlusions: Technique and Sizing

Recanalizing post-thrombotic occlusions requires oblique imaging to find the true lumen, general anesthesia for comfort, pre-dilation to the planned stent size, and typical common iliac to common femoral sizing of 14 to 16mm stepping down to 12mm.
