目的：探讨血管外膜囊性病变的超声表现，评价彩色多普勒超声对血管外膜囊性病变的诊断价值。方法回顾性分析我院超声科12例血管外膜囊性病变患者的超声图像表现。结果本组12例患者术前确诊8例，误诊4例，12例患者均为单发，7例位于腘动脉，4例位于髂外动脉-股动脉，1例位于髂外静脉，根据囊肿形态及管腔的狭窄特点可分为偏心性囊肿和向心性囊肿，偏心性囊肿8例，向心性囊肿4例，超声显示患者受累血管外壁均出现不同程度增宽，横切见血管外形无改变，管腔受压，内径变细，11例动脉受累的患者，囊肿与管腔之间可见3层管壁结构，狭窄处血流收缩期峰速度可加快，频谱形态呈湍流样改变，病变远心端动脉血流峰速度减低，病变位于静脉的1例患者，远心端静脉管腔增宽，血流缓慢，血管造影显示受累动脉处管腔狭窄，CT可见管腔外单腔或多腔肿物，管腔呈充盈缺损或变细，12例病例均行囊肿切除及血管外膜剥离术。结论彩色多普勒超声能够准确显示CAD患者囊肿的位置、形态和内部回声等，准确评价管腔狭窄特点、程度和血流状态，对CAD的诊断、治疗和预后有重要的临床意义。

Objective To explore the ultrasonic characteristics of cystic adventitial disease and to evaluate the value of color doppler ultrasound in diagnosis of cystic adventitial disease.MethodsRetrospectively analyzed the ultrasonograms and other imaging methods of twelve patients with cystic adventitial disease conformed by surgery in nanyang central hospital.Results Eight of the twelve cystic adventitial disease cases were confirmed by color doppler ultrasound before surgery, and five were misdiagnosed, all the cases were single, with seven in popliteal artery, four in iliofemoral artery, and one in external iliac vein, were divided into the cysts into concentric cysts and eccentric cysts according to the cystic shape and the lumen stenosis, eight cases were eccentric cysts, four cases were concentric cysts, and both had septations, the affected vessel expanded, but its shape did not change and the lumen was compressed, there were three layers of wall between the cyst and the lumen, the peak systolic velocity of the affected lumen increased and the distal end systolic peak velocity decreased when lesion occurred in artery, distal end lumen reflux were slow when lesion occurred in distal veins, angiography showed the stenosis of the affected lumen, CT showed uniorlocular or multilocular cyst, and the compressed lumen, all of the eleven patients underwent the diseased adventitia resected along with excision of the cyst. Conclusion The color doppler ultrasound can display the location, shape, and internal echo of cystic adventitial disease, and thus it can accurately evaluate luminal stenosis and lfow pattern, this is of important clinical signiifcance for the diagnosis, treatment, and prognosis of cystic adventitial disease.
