Iliac Artery Occlusion Following Iliac Vein Recanalization and Stenting in Two Patients.

Abstract

Ileocaval venous thrombosis and outflow obstruction is a condition with many possible causes that typically presents with symptoms related to venous congestion or insufficiency. Recent device development and availability of endovascular stenting and venoplasty for lifestyle-limiting symptoms refractory to conservative management has led to increased interest in these procedures. While several common complications of venous stent placement have been well-described, 1 uncommon and emergent complication is nearby arterial compression or occlusion. Here we present 2 cases of iliac artery occlusion occurring after iliac venous recanalization and stenting, and discuss possible factors that may contribute to this uncommon complication.
