Carotid angioplasty and stenting versus carotid endarterectomy: Randomized trial in a community hospital

OBJECTIVES The goal of this study was to determine whether carotid angioplasty and stenting (CAS) is equivalent to carotid endarterectomy (CEA) in patients with symptomatic carotid stenosis > 70% by a randomized, controlled trial in a community hospital. BACKGROUND Carotid angioplasty and stenting has been suggested to be as effective as CEA for treatment of symptomatic carotid artery stenosis. METHODS A total of 104 patients presenting with cerebrovascular ischemia ipsilateral to carotid stenosis were selected randomly for CEA or carotid stenting and followed for two years. RESULTS Stenosis decreased to an average of 5% after CAS. The patency of the reconstructed artery remained satisfactory regardless of the technique as determined by sequential ultrasound. One death occurred in the CEA group (1/51); one transient ischemic attack occurred in the CAS group (1/53); no individual sustained a stroke. The perception of procedurally related pain/discomfort was similar. Hospital stay was similar, although the CAS group tended to be discharged earlier (mean = 1.8 days vs. 2.7 days). Complications associated with CAS prolonged hospitalization when compared with those sustaining a CEA-related complication (mean = 5.6 days vs. 3.8 days). Return to full activity was achieved within one week by 80% of the CAS group and 67% of the patients receiving CEA. Hospital charges were slightly higher for CAS. CONCLUSIONS Carotid stenting is equivalent to CEA in reducing carotid stenosis without increased risk for major complications of death/stroke. Because of shortened hospitalization and convalescence, CAS challenges CEA as the preferred treatment of symptomatic carotid stenosis if a reduction in costs can be achieved.
