Endovascular Solution of Acute Limb Ischemia Engendered by Persistent Sciatic Artery Pseudoaneurysm due to Stent Fracture.

ABSTRACT

We report a case of acute limb ischemia (ALI) due to a thromboembolism from a persistent sciatic artery (PSA) pseudoaneurysm precipitated by a fractured stent. Patient, previously treated for ALI by fibrinolysis and stent implantation, presented with a PSA pseudoaneurysm (undetected during first hospitalization), stent fracture (SF), and occlusion of vessels below the knee. Fibrinolysis was performed, restoring direct flow to the foot. A week later, an endovascular procedure was attempted to reline SF and exclude the PSA pseudoaneurysm by deployment of two 13 × 100-mm peripheral endografts (Viabahn; W.L. Gore & Associates, Flagstaff, AZ). At 1-year follow-up, patient was asymptomatic without further clinical events.
