目的评价主动脉夹层累及颈动脉的超声图像特点。方法采用PILIPS7500彩色多普勒超声诊断仪,对29例患者经常规心脏超声检查诊断为主动脉夹层后,切换至颈动脉检查模式,观察颈动脉内膜是否累及,夹层撕裂至颈动脉的图像特点、血流状态。结果 29例患者中,夹层累及颈动脉7例,占24.1%,均发生在Standford A型患者。其中4例颈动脉超声清晰显示撕裂飘浮的内膜,真假腔血流状态不同。左颈总动脉或右颈总动脉假腔内血栓形成、真腔狭窄各1例。另1例右颈总动脉近完全闭塞,无血流信号。结论颈动脉超声能准确评估主动脉夹层患者颈动脉受累情况。
Objective To evaluate the characteristics of aortic dissection involving the carotid artery. Methods PILIPS7500 color Doppler ultrasound diagnostic apparatus, 29 patients after routine cardiac ultrasound diagnosis of aortic dissection, switch to the carotid artery examination mode to observe whether the carotid artery intima, dissection tear to the carotid artery image Features, blood flow status. Results Among the 29 patients, 7 cases (24.1%) had carotid involvement in the dissection occurred in Standford type A patients. 4 cases of carotid artery ultrasound clearly shows the tear floating intima, true and false cavity blood flow state is different. Left carotid artery or right common carotid artery thrombosis within the false lumen, true cavity stricture in 1 case. Another case of right common carotid artery nearly completely occluded, no blood flow signal. Conclusion Carotid artery ultrasound can accurately assess the carotid artery involvement in patients with aortic dissection.
