目的：综合分析多层螺旋CT三维血管造影在腹部血管性疾病中的应用及对治疗预后的影响。方法：采取回顾性研究方法，在2014年11月~2016年10月，选取在我院收治的76例腹部血管性疾病患者临床资料作为研究对象，按照不同的诊断方法分为实验组与对照组（每组均为38例）。实验组应用多层螺旋CT三维血管造影方法，对照组应用腹部彩超诊断方法。采用SPSS20.0统计学软件进行统计学分析两组患者的正确诊断率（以手术病理诊断为参照对比实验组与对照组两种方法的正确诊断率）。结果：实验组正确诊断率为97.37%（37/38，10例门静脉系统疾病、5例腹主动脉瘤、5例脾血管瘤、6例肝血管瘤、7例肾动脉钙化狭Õ、2例腹主动脉钙化狭Õ、1例肠系膜上动脉钙化狭Õ、1例骼动脉钙化狭Õ），对照组正确诊断率为81.58%（31/38，4例门静脉系统疾病、2例腹主动脉瘤、2例脾血管瘤、8例肝血管瘤、4例肾动脉钙化狭Õ、5例腹主动脉钙化狭Õ、3例肠系膜上动脉钙化狭Õ、3例骼动脉钙化狭Õ），实验组正确诊断率远远高于对照组。结论：多层螺旋CT三维血管造影在腹部血管性疾病中的应用价值比较高，可以多方位地观察腹部血管疾病血管走行状况。

Objective To analyze the application of multislice spiral CT three-dimensional angiography in abdominal vascular disease and its effect on prognosis. Methods A retrospective study was conducted. From November 2014 to October 2016, 76 patients with abdominal vascular diseases admitted to our hospital were selected and divided into two groups according to different diagnostic methods: experimental group and control group (38 patients in each group). Multi-slice spiral CT angiography was used in the experimental group, and the control group was diagnosed by color Doppler ultrasonography. SPSS20.0 statistical software for statistical analysis of the two groups of patients the correct diagnosis rate (in order to compare the pathological diagnosis of experimental and control groups, the two groups the correct diagnosis rate). Results The correct diagnosis rate of the experimental group was 97.37% (37/38, 10 cases of portal vein disease, 5 cases of abdominal aortic aneurysm, 5 cases of splenic hemangioma, 6 cases of hepatic hemangioma, 7 cases of renal artery calcification stenosis, 2 cases 1 case of calcific stenosis of superior mesenteric artery and 1 case of calcified stenosis of aorta), the correct diagnosis rate of the control group was 81.58% (31/38, 4 cases of portal vein disease, 2 cases of abdominal aortic aneurysm, 2 cases of splenic artery 4 cases of renal artery calcification stenosis, 5 cases of abdominal aortic calcification stenosis, 3 cases of superior mesenteric artery calcification stenosis, 3 cases of calcified artery stenosis), experimental group, the correct diagnosis rate is much higher than the control group. Conclusion Multislice spiral CT three-dimensional angiography in the abdominal vascular disease is of high value, can be multi-directional observation of abdominal vascular disease vascular running conditions.
