Bilateral Iliac Arteries Stent Compression Following Pelvic Surgery: A Case Report and Review of Literature

Abstract

Extrinsic compression of iliac arteries stents has been reported from different causes, such as uterine fibroids and orthopedic surgery. Although extrinsic compression of stents in the iliac veins has been widely studied, stent compression in the iliac arteries is less common. Here we presented a case with bilateral common iliac arteries stent compression following pelvic surgery. A patient (65-year-old woman) presented with acute critical right limb ischemia. Computed tomography angiography (CTA) showed occlusion of the right common and external iliac artery, and severe stenosis in the left common iliac artery. In addition, there was evidence of a Brenner tumor originating from the left ovary. The patient underwent endovascular recanalization of the right iliac arteries and bilateral balloon-expandable stent deployment, and the ovarian tumor was removed after three weeks. The control CTA scan showed asymmetric bilateral iliac arteries stent compression more prominent on the right side, then self-expanding stents were implanted bilaterally. In Conclusion although iatrogenic compression of the stent in the iliac artery is rare despite scarcity, it is important to maintain a high index of suspicion in selected cases and choose the proper stent accordingly.
