Clinical analysis of microsurgical carotid endarterectomy for carotid stenosis and occlusion / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical effects of carotid endarterectomy for carotid stenosis and occlusion.</p><p><b>METHODS</b>From August 2005 to November 2008 moderate and severe carotid stenosis or occlusion were found in 16 patients by Doppler ultrasonography (DUS), MRA, CTA, DSA. The stenosis degree ranged from 60% to 99% in 14 patients and complete occlusion in 2 patients. Twelve patients underwent standard carotid endarterectomy (sCEA) in whom 2 patients were placed carotid shunt and 1 patient underwent carotid patch angioplasty. Four patients underwent eversion carotid endarterectomy (eCEA). All operations were performed by microscope.</p><p><b>RESULTS</b>There was no stroke, transient ischemic attack and mortality perioperatively and during follow-up from 1 month to 3 years. The ICA flow detected by follow-up duplex scan and MRA was unobstructed. The primary cerebral ischemic symptoms were obviously improved or disappeared after operation. The postoperative complications included one case of upper gastrointestinal hemorrhage and one case of hoarseness and bucking, which disappeared after medical treatment.</p><p><b>CONCLUSIONS</b>CEA is an effective way for treating carotid stenosis. Different operative methods and techniques deal with different carotid lesions to achieve better effect. Microsurgical technique is useful for exposure of high ICA bifurcation and avoid effectively cranial nerve injury and other complications.</p>
