Abstract
The purpose of this study was to evaluate the efficacy and safety of staged carotid stenting (CS) and carotid endarterectomy (CEA) for bilateral internal carotid artery stenosis.
With this strategy, initial carotid stenting was performed for the high grade carotid stenosis to reduce the risk of subsequent CEA. Eight patients were treated with staged CS and CEA; CS for asymptomatic side followed by CEA for symptomatic side. Sufficient revascularization was obtained in all procedures but one CS procedure.
Two minor stroke caused by distal embolism occurred during the perioperative period of CS. Postprocedural persistent hypotension was observed in one CS procedure. The mean interval between CS and CEA was 19.8 days. In conclusion, although our strategy has some advantages such as avoidance of bilateral cranial nerve palsy and shorter admission period over staged CEA, relatively high complication rate was noted at the first CS without any stroke morbidity post CEA.
Our preliminary result showed that further reduction of periprocedural complication rate at the initial stenting is mandatory for this approach justified.
