目的探讨64排螺旋CT血管成像诊断肠系膜上动脉病变的价值。方法回顾分析72例行CT血管成像(CTA)诊断的肠系膜上动脉病变患者的临床资料,记录并分析CTA诊断结果。结果本组72例患者均顺利完成扫描且获得满意图像:37例肠系膜上动脉(SMA)缺血性病变(7例SMA急性栓塞、30例SMA慢性狭窄),21例SMA夹层(9例孤立性SMA夹层、12例腹主动脉夹层累及SMA),14例SMA压迫综合征(11例十二指肠淤滞症、3例胡桃夹综合征)。结论 64排螺旋CT血管成像具有定位准确、成像清晰等优点,有助于医师多角度观察肠系膜上动脉病变的具体情况。
Objective To investigate the value of 64-slice spiral CT angiography in the diagnosis of superior mesenteric artery disease. Methods The clinical data of 72 patients with superior mesenteric artery disease diagnosed by CT angiography (CTA) were retrospectively analyzed. The diagnostic results of CTA were recorded and analyzed. Results All of the 72 patients in this study were scanned satisfactorily and the images were satisfactory: 37 cases of ischemic lesions of the superior mesenteric artery (7 cases of acute SMA embolization and 30 cases of chronic SMA stenosis) and 21 cases of SMA dissection SMA dissection, 12 cases of abdominal aortic dissection involving SMA), 14 cases of SMA compression syndrome (11 cases of duodenal stasis, 3 cases of nutcracker syndrome). Conclusion 64-slice spiral CT angiography has the advantages of accurate positioning and clear imaging, which helps doctors to observe the specific situation of the superior mesenteric artery disease from multiple angles.
