摘要
目的 :探讨多层螺旋CT(MSCT)在周围血管疾病中的应用价值。方法 :对 18例临床怀疑周围血管疾病的患者 ,均行上肢或下肢动脉或静脉CT血管造影。动脉系统疾病经肘前静脉以 3ml/s流率注入 10 0ml对比剂 ,延迟 2 5～40s后扫描 ;静脉性疾病经足背静脉或手背静脉以 1ml/s流率注入 5 0ml对比剂 ,延迟时间为 60～ 70s。扫描条件为层厚3 .2mm ,重建间隔 1.6mm ,螺距 1.2 5。结果 :动脉系统疾病 10例 ,狭窄或闭塞性疾病 9例 ,其中 1例合并动脉瘤 ,1例传统血管造影均不能插管操作 ,1例动脉瘤MRA以及传统血管造影均没有做出正确诊断 ;1例为正常下肢动脉。静脉系统疾病 3例 ,其中下肢深静脉血栓 2例 ,上肢多发性静脉瘤 1例 ,经传统血管造影证实。结论 :应用MSCT诊断周围血管疾病有一定的临床价值。
Objective:To discuss the value of multislice heical CT in detecting peripheral vessel diseases.Methods:Angiography of upper extremity was performed in 18 cases. The scans of arterial system began at the time of 25s to 40s after the initiation of 100ml contrast media injection with the rate of 3ml/s through antecubital vein. The scans of venous system started at the time of 60s to 70s after the initiation of 50ml contrast media injection with the rate of 3ml/s through the vein of instep or back of hand. CT scanning parameters were used at 3.2mm slice thickness,1.6mm reconstruction interval and 1.25 pitch.Results:10 cases of arterial diseases,occlusive or stenosis diseases accounted for 9 cases,in which one case had popliteal aneurysm.Conventional angiography had failed in one case.MR angiography and conventional angiography could not make a correct diagnosis of the popliteal aneurysm.One case was normal.Three cases of venous diseases,including 2 cases of deep venous thrombosis and one case of multiple venous aneurysm of the upper extremity,were identified by conventional angiography.Conclusion:MSCT is of a positive clinical value in detecting peripheral vascular diseases.
