A Case of Delayed Carotid Artery Dissection after CASPER Rx Stent Deployment

Abstract

Carotid artery stenting (CAS) was performed on a 72-year-old man with severe symptomatic right cervical internal carotid artery stenosis. Considering the unstable plaque and highly tortuous lesion, an Mo.Ma embolic protection device (EPD) and a CASPER Rx stent were used. There were no obvious complications during the perioperative period. However, angiography performed one year after CAS showed that the stent placement site had straightened, and vascular dilation was observed near the distal edge of the stent. It was diagnosed as a chronic internal carotid artery dissection. As the patient was asymptomatic, a decision was made to observe the patient. Iatrogenic dissection during CAS may be caused by catheter, wire, or EPD manipulation. We report a case of delayed internal carotid artery dissection after CASPER Rx stent placement.
