This study evaluated the efficacy of duplex ultrasonographic scanning in assessing the status of carotid arteries after 155 endarterectomies in 131 patients. Duplex studies were done as early as one month and as late as 96 months postoperatively; 33 patients had serial studies. Only 59 (42%) of 142 arteries had no evidence of irregularity or reduction in diameter at the operative site. An additional 41 (29%) had a reduction in diameter between 10% and 29%; 19 (13%) had reductions of 30% to 49%; nine (6%) from 50% to 69%; six (4%) from 70% to 99%; and eight (6%) were occluded. In 51 vessels, angiographic studies confirmed the duplex findings. Symptoms suggestive of recurrent cerebrovascular disease occurred postoperatively in 25 instances; in only three were the anatomic findings suggestive of lesions appropriate to the symptoms. We conclude that duplex ultrasonographic scanning is a useful technique for assessing carotid arteries after endarterectomy and that postoperative narrowing of vessels occurs more commonly than suspected.
本研究评估了双功超声扫描在评估131例患者155次动脉内膜切除术后颈动脉状况中的有效性。双功超声检查最早在术后1个月进行，最晚在术后96个月进行；33例患者进行了系列检查。在142条动脉中，只有59条（42%）在手术部位没有不规则或直径减小的迹象。另外41条（29%）直径减小10%至29%；19条（13%）直径减小30%至49%；9条（6%）直径减小50%至69%；6条（4%）直径减小70%至99%；8条（6%）发生闭塞。在51条血管中，血管造影研究证实了双功超声检查的结果。术后有25例出现提示复发性脑血管疾病的症状；只有3例解剖学检查结果提示存在与症状相符的病变。我们得出结论，双功超声扫描是评估动脉内膜切除术后颈动脉的一种有用技术，而且术后血管狭窄的发生率比预想的更常见。
