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 investigate the 64-slice spiral CT and CTA findings of acute abdomen caused by vascular lesions (ABCVL). Methods The CT scan and CTA findings of 9 cases confirmed by imaging and clinical confirmation of ABCVL were retrospectively analyzed. Results Total hepatic aneurysm was associated with partial thrombosis (1 case), superior mesenteric artery aneurysm with thrombosis (1 case), superior mesenteric artery embolization with superior mesenteric vein thrombosis (1 case), left renal artery infarction (1 case), mesenteric artery torsion (2 cases) Thrombus formation in 3 cases; 64-slice CT three-dimensional post-processing image clearly shows the aneurysm size and shape, the mesenteric artery torsion, intraluminal low density thrombosis, with exudate, ascites and so on. Conclusion Some CT scan of the abdomen can show ABCVL. The diagnosis of ABCVL can be confirmed by 64-slice spiral CT angiography. To some extent, the severity of ABCVL can be judged.
