血管源性急腹症的64排螺旋CT表现

The 64 row Spiral CT Findings of Acute Abdomen Caused by Vascular Lesions

目的探讨血管源性急腹症(acute abdomen caused by vascular lesions,ABCVL)的64排螺旋CT平扫及CTA表现。方法回顾分析9例经影像及临床证实ABCVL的CT平扫及CTA表现。结果肝总动脉瘤伴部分血栓形成1例,肠系膜上动脉瘤伴血栓形成1例,肠系膜上动脉栓塞并肠系膜上静脉血栓形成1例,左肾动脉分支梗死1例,肠系膜动脉扭转2例,门静脉血栓形成3例;64排CT三维后处理图像清晰显示动脉瘤腔大小及形态、肠系膜动脉扭转情况、血管腔内低密度血栓,伴随渗液、腹腔积血等情况。结论腹部CT平扫的某些征象可提示ABCVL;64排螺旋CTA成像可明确ABCVL的诊断,在一定程度上可判断ABCVL的严重程度。

Objective To explore the CT characteristics of acute abdomen caused by vascular lesions with 64 row spiral CT and CT angiography.Methods Retrospective analysis of plain CT and CTA of 9 cases with ABCVL proved by imaging and clinical was taken.Results There were 1 case of common hepatic artery aneurysm with partial thrombosis,1 case of superior mesenteric artery aneurysm with thrombosis,1 case of superior mesenteric artery embolism and superior mesenteric vein thrombosis,1 case of left renal artery branch infarction,2 cases of mesenteric artery torsion,3 cases of portal vein thrombosis.The aneurysm cavity size and morphology,mesenteric artery torsion condition,endovascular hypodensity thrombosis,accompanied by exudative liquid and hemoperitoneum and so on were clearly shown on the 3D processing imaging by 64 row spiral CT.Conclusion Some signs on plain CT may suggest the ABCVL,the definite diagnosis of ABCVL can be made through 64 row SPIRAL CTA,the severity of ABCVL can be judged in a certain extent.
