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

## TL;DR

This paper reports two cases where artery blockage occurred after vein treatment, highlighting a rare but serious complication of venous stenting.

## Contribution

The paper presents two new case reports of iliac artery occlusion following venous stenting, adding to the understanding of rare complications.

## Key findings

- Iliac artery occlusion occurred in two patients after iliac vein stenting.
- The cases suggest a possible link between venous stent placement and nearby arterial compression or occlusion.

## 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.
