目的探讨多层CT肠系膜血管成像的临床应用价值。方法对17例不明原因腹痛患者行常规腹部动脉期和静脉期扫描后,分别进行肠系膜动脉和静脉成像,成像方法常规采用MIP和VR,需要时加MPR或CPR,描述肠系膜血管病变的表现。结果17例患者中8例显示肠系膜血管病变。1例肠系膜上动脉(SMA)和肠系膜下动脉(IMA)中断;3例SMA见局限性狭窄,其中1例并侧支血管形成;1例见SMA近端动脉瘤。3例SMV血栓形成,其中2例表现为SMV不显影,1例表现为SMV内充盈缺损。结论多层CT肠系膜血管成像是肠系膜血管病变的一种无创、准确、快捷的检测方法。
Objective To investigate the clinical value of multi-slice CT mesenteric angiography. Methods Seventeen patients with unexplained abdominal pain underwent routine abdominal and venous phase scanning. Mesenteric arteries and veins were respectively imaged. MIP and VR were routinely used in imaging. MPR or CPR was used to describe the manifestation of mesenteric vascular disease. Results Of the 17 patients, 8 showed mesenteric vascular lesions. 1 case of superior mesenteric artery (SMA) and inferior mesenteric artery (IMA) interrupted; 3 cases of SMA see limited stenosis, including 1 case of collateral vessels and 1 case of SMA proximal aneurysm. Three cases of SMV thrombosis, including 2 cases showed no development of SMV, 1 cases showed SMV filling defect. Conclusion Multi-slice CT mesenteric angiography is a non-invasive, accurate and rapid detection method of mesenteric vascular disease.
