| 目的 观察血管外膜囊肿（CAD）的超声表现。方法 回顾性分析9例经手术后病理证实的CAD的超声声像图表现。结果 9例CAD中，7例单发，均见于腘动脉；2例多发，其中1例发生于股动脉，1例发生于髂外静脉。超声诊断正确7例，1例误诊为夹层动脉瘤伴血栓形成，1例误诊为腹股沟淋巴结肿大。声像图中CAD表现为囊性无回声区，与管壁关系密切，管腔局部可受压变细；发生于动脉者病变远心端收缩期峰速正常或相对减低；发生于静脉者病变处远心端回流速度缓慢。结论 彩色多普勒超声能够显示CAD形态、评估管腔受压程度，为诊断和术后随访提供有力依据。 |

| Objective To explore ultrasonic characteristics of cystic adventitial disease (CAD). Methods Ultrasonograms of 9 patients with operation and pathology proved CAD were retrospectively analyzed. Results In 9 cases of CAD, 7 had single lesion located in popliteal artery, 2 had multiple lesions, in one located in femoral artery and in the rest one located in external iliac vein. Ultrasound correctly diagnosed CAD in 7 patients, while in 1 misdiagnosed as aneurysm thrombus, and in the rest one as inguinal lymphnodes. CAD present as anechoic masses involving artery or vein and compressed the vascular. Distal end systolic peak velocity was normal or relatively low when lesions occurred in artery, and distal end lesions reflux were slow when occurred in distal veins. Conclusion Color Doppler ultrasound can display the shape of CAD and evaluate vascular compression, which may provide evidences for clinical diagnosis and postoperative follow-up. |
