Balloon occlusion superior mesenteric arteriography and nonocclusion superior mesenteric arteriography were compared prospectively and retrospectively for adequacy of mesenteric and portal venous visualization. Prospective, occlusion studies in 20 patients were uniformly judged of excellent visual quality, while retrospectively, only 30% of nonocclusion studies from 20 other patients were considered optimal. In 10 of the patients who had balloon occlusion superior mesenteric arteriography, the procedure was preceded by a control nonocclusion superior mesenteric arteriography study. In only two (20%) patients was the nonocclusion study rated of excellent visual quality. Each study was assessed a rating of 0-3, according to how well the mesenteric and portal venous system visualized. Prospectively, all 20 balloon occlusion superior mesenteric arteriography studies were given the highest obtainable rating (3). Retrospectively, only six (30%) 20 nonocclusion superior mesenteric arteriography studies received a rating of 3; hence, 14 (70%) of the nonocclusion studies were rated less than excellent in visual quality when looked at retrospectively. No complications occurred with balloon occlusion superior mesenteric arteriography, and the occlusion procedure consistently gave excellent visualization of the mesenteric and portal venous anatomy.
前瞻性和回顾性地比较了球囊闭塞性肠系膜上动脉造影和非闭塞性肠系膜上动脉造影在肠系膜和门静脉显影方面的充分性。20例患者的前瞻性闭塞性研究均被判定为视觉质量极佳，而回顾性地看，另外20例患者的非闭塞性研究中只有30%被认为是最佳的。在10例进行了球囊闭塞性肠系膜上动脉造影的患者中，该操作之前进行了对照性非闭塞性肠系膜上动脉造影研究。只有2例（20%）患者的非闭塞性研究被评为视觉质量极佳。根据肠系膜和门静脉系统的显影情况，每项研究被评定为0至3分。前瞻性地，所有20例球囊闭塞性肠系膜上动脉造影研究都获得了可获得的最高评分（3分）。回顾性地看，20例非闭塞性肠系膜上动脉造影研究中只有6例（30%）获得了3分；因此，回顾性分析时，14例（70%）非闭塞性研究的视觉质量被评为低于极佳。球囊闭塞性肠系膜上动脉造影未发生并发症，闭塞操作始终能很好地显示肠系膜和门静脉的解剖结构。
