Sixty-six patients (72 carotid arteries) were examined after carotid endarterectomy (CEA) using Doppler colour flow imaging (DCFI). Examinations were performed 4-18 days (mean: 7 days) after surgery (32 patients, 34 arteries) or between 2 and 100 months (mean: 39 months) after CEA (34 patients, 38 arteries). Minor vessel wall abnormalities were found in 36% in the internal carotid artery (ICA) and in 55% in the common carotid artery (CCA) or bifurcation. One patient had a minor residual ICA stenosis after surgery; two low-grade stenoses and three ICA-occlusions were diagnosed at follow-up. Altered flow patterns occurred most in CCA (90%) and were predominantly located adjacent to the vessel wall and in dilated vascular segments of the CCA. Disturbed haemodynamics in the ICA were less marked (57%) and frequently found in the central vessel lumen or diffusely distributed. We conclude that surgically induced changes of the vessel geometry and residual or recurrent vascular wall abnormalities are often associated with distinct haemodynamic disturbances, which can reliably be detected by DCFI.
66例患者（72条颈动脉）在接受颈动脉内膜切除术（CEA）后，采用彩色多普勒血流成像（DCFI）进行检查。术后4 - 18天（平均7天）对32例患者（34条动脉）进行检查，或在CEA术后2至100个月（平均39个月）对34例患者（38条动脉）进行检查。在内颈动脉（ICA）中发现36%存在轻微血管壁异常，在颈总动脉（CCA）或分叉处发现55%存在异常。1例患者术后存在轻微残余ICA狭窄；随访时诊断出2例轻度狭窄和3例ICA闭塞。血流模式改变最常出现在CCA（90%），主要位于血管壁附近以及CCA的扩张血管段。ICA中的血流动力学紊乱不太明显（57%），且常出现在血管中央腔或呈弥漫分布。我们得出结论，手术引起的血管几何形状改变以及残余或复发性血管壁异常通常与明显的血流动力学紊乱相关，DCFI能够可靠地检测到这些紊乱。
