Endovascular Treatment of a Carotid Pseudoaneurysm Using the New Double-Layer Micromesh Stent (Roadsaver^®)

Pseudoaneurysm (PA) formation after carotid endarterectomy (CEA) is a very uncommon but dangerous complication, potentially responsible for cerebral embolism or rupture. Therefore, the PA treatment is imperative. Until few years ago, the treatment of choice was represented by open surgical repair, with a higher mortality and morbidity rate than primary operation. Actually, the advancements in endovascular procedures allow the surgeon the possibility to recur to a less invasive approach in the presence of an adequate anatomy, reducing the risk of cranial nerve injuries. We present a case of post-CEA PA successfully treated using the double-layer micromesh stent (Roadsaver^®; Terumo, Tokyo, Japan), with almost immediate thrombosis of the aneurysmal sac.
