摘要
目的探讨64排128层螺旋CTA对自发性孤立性肠系膜上动脉夹层(spontaneous isolated superior mesen-terric artery disection,SISMAD)的显示方法及诊断价值。方法回顾性分析64排128层螺旋CTA诊断SISMAD的患者资料8例,总结及优化扫描方案,采用多种后处理方法显示。结果共诊断SISMAD 8例,SISMAD起止的长度在10～75 mm之间;夹层发生的部位7例靠近于肠系膜上动脉(SMA)近段,其中3例发生于SMA近心端距SMA开口处约10～30 mm;1例起于发出胰十二指肠下动脉后。发现3处及以上破口的SISMAD 5例,发现2处破口1例,发现1处破口2例。部分假腔内可见血栓形成。结论 SISMAD涉及的多种病理改变64排128层螺旋CTA均可清楚显示,可作为诊断SISMAD的首选影像学检查手段。
Objective To analyze the 128 slice CT angiography findings of spontaneous isolated superior mesenterric artery dissection （SISMAD）. Methods Eight cases of SISMAD were enrolled in the study. The CT findings and optimal post processing method were analyzed retrospectively. Results The length of SISMAD ranged from lOmm to 75 mm. SIS- MAD located at the proximal segment of SMA in 7 cases, 10 -30 mm from the site of SMA in 3 cases, located at the inferior pancreaticoduodenal artery in 1 case. More than 3 teared ruptures of SISMAD were found in 5 cases, two ruptures in 1 case, one rupture in 2 cases. Thrombosis was found in partial false lumen. Conclusion Pathological changes of SISMAD were showed clearly on CTA, 128 slice CTA can be used as the first choice method in diagnosing SISMAD.
