Management of Persistent Sciatic Artery Embolization to the Lower Extremity Using Covered Stent through a Transgluteal Approach

Previous studies have used endovascular stenting in the setting of aneurysms and stenosis of the PSA.2' 3 Although there is risk for aneurysmal degeneration to occur near the region of the greater sciatic foramen, there was no indication to perform a prophylactic bypass and exclusion to prevent this complication because the natural history and the formation of a PSA aneurysm are not well defined. The stent, however, was placed in an atheroembolic segment of the PSA less likely to result in aneurysmal formation.1 The clinical presentation and angiographic findings suggest a thromboembolic event :hat occurred.
