彩色多普勒超声在下肢慢性动脉闭塞性疾病手术前后的应用

目的：探讨彩色多普勒超（CDU）在下肢慢性动脉闭塞性疾病手术前后的应用价值，方法：对30例例患者下肢动脉同时进行了CDU和数字减影血管造影（DSA）检查，9例血管移植术后进行了超声随访。结果：20例DSA显示动脉闭塞，其中18例（90％）CDU检查结果相吻合，9例DSA为单个或多个动脉节段显著性狭窄，其中6例（66．7％）CDU判断正确。1例双下肢动脉DSA结果相吻合。9例DSA为单个或多个动脉节段显著性狭窄，其中6例（66．7％）CDU判断正确。1例双下肢动脉DSA和CDU均未见异常。7例血管移植物血流通畅。2例PTFE移植物术后急性血栓形成，1例小腿层血肿。结论：CDU是下肢慢性动脉闭塞性疾病术前评价和术后随访有价值的方法。

Preoperative and Postoperative Assessing for Chronic Occlusive Arterial Diseases in Lower Limbs Using Color Doppler Ultrasound

Objective:To explore the value of color Doppler ultrasound(CDU)for the examination of chronic occlusive arterial diseases in lower limbs before and after operation.Methods:Thirty patients were examined by CDU and DSA.Vascular bypass grafts in 9 patients were assessed after operation.Results:Twenty patients had occlusive lesions confirmed by DSA,and 18 patients(90%)got the same results using CDU.CDU revealed diagnostic according with DSA in 6 of 9 patients with single or multilevel segmental significant stenosis.One patient was normal both in DSA and CDU.Vascular grafts in 7 patients had normal flow.2 patients had acute thrombosis in grafts.One patient had muscular hematoma in the calf.Conclusions:(CDU) is a valuable method for preoperative assessment and postoperative followup of chronic occlusive arterial diseases in lower limbs.
