主动脉弓血栓彩超检查在CIS的临床应用

The Clinical Application of CIS about Color Doppler Examination of Aortic Arch Thrombosis

目的探讨主动脉弓血栓彩超检查在缺血性脑卒中(CIS)诊治中的重要性及常规检查的可行性。方法纳入经CT或MRI确诊为首发CIS的患者52例作为观察组,并纳入同期门诊查体者48例作为对照组,均进行主动脉弓彩超检查。观察CIS患者主动脉弓血栓的发病率、1年内CIS的复发率及主动脉弓斑块的有无、部位、形态、大小等与病情发生发展和预后的关系。结果观察组52例患者中34例主动脉弓有斑块存在;有主动脉弓斑块组较无主动脉弓斑块组1年内CIS复发率高;IMT≥4mm者较厚度<4mm者复发率高;复合型斑块较单纯型斑块CIS复发率高;主动脉弓近端斑块较主动脉弓远端斑块CIS复发率高;管腔狭窄率≥50%者较<50者CIS发病率高。对照组48例受检者中仅5例主动脉弓有斑块存在,与观察组有明显差异(P<0.05)。结论 CIS患者中主动脉弓血栓的发病率较高,主动脉弓斑块的大小、部位、性质、管腔狭窄率等与CIS的预后有密切关系。

Objective To evaluate Ultrasonography of aortic arch thrombosis in Cerebral ischemic stroke（CIS） and the importance of diagnosis and treatment of the feasibility of routine examination.Methods The 52 patients who were confirmed by CT or MRI as the first CIS composed an observation group,and the 48 Out-patient in the same time composed the control group.The aortic arch ultrasonography were used in both the two groups.Then observe the CIS patients the incidence of aortic arch thrombosis,the recurrence rate within one year of CIS and the relationship between presence or absence of patch、the plaque size,location,nature and rate of stenosis and the development of disease and prognosis.Results 52 patients in the observation group,34 cases of aortic arch plaques exist;the recurrence rate of CIS within one year in aortic arch plaque group is higher than the group without aortic arch plaqu;the IMT≥4mm cases compared to those 4mm by a high CIS rate of recurrence;Complex compsred to those simple plaque-type plaques by a high CIS recurrenrate;Proximal aortic arch plaques compared to distal aortic arch plaques by a high CIS recurrence rate;Rate≥50% stenosis compared to those ＂50 by a high incidence of CIS.Control group subjects,only 5 cases exsisted aortic arch plaques in the total 48 cases,which exsists significant difference with the observation group（P0.05）.Conclusion There is a high incidence with aortic arch of thrombosis of CIS patients.Aortic arch plaque size,location,nature and rate of stenosis are closely related with the prognosis of CIS.
