Angiographic findings of the vitelline artery in five patients with surgically proven Meckel's diverticulum were reviewed retrospectively. Superselective vitelline arteriography was performed in two patients and superior mesenteric arteriography in three. Arteriography showed the elongated artery without branching originating from the distal ileal artery and a group of tortuous vessels at the distal portion of this artery in all patients. A dense capillary staining of the vitelline artery was exclusively shown in patients with ectopic gastric mucosa. In one patient, injection of methylene blue intraoperatively through a previously placed angiographic catheter into the vitelline artery stained only the vitelline artery and Meckel's diverticulum in blue but neither the mesentery nor the ileum. Demonstration of a nonbranching artery from the ileal artery and a group of dilated tortuous vessels at the distal portion of this artery should suggest the possibility of Meckel's diverticulum and can be confirmed by selective injection of the artery. It should be emphasized that angiography can detect Meckel's diverticulum even in the absence of acute bleeding.
回顾性分析了5例经手术证实为梅克尔憩室患者的卵黄动脉血管造影结果。2例行超选择性卵黄动脉造影，3例行肠系膜上动脉造影。血管造影显示，所有患者均可见起源于回肠远端动脉的无分支延长动脉及其远端的一组迂曲血管。仅在异位胃黏膜患者中出现卵黄动脉浓密的毛细血管染色。1例患者术中通过预先放置的血管造影导管向卵黄动脉注射亚甲蓝，结果仅使卵黄动脉和梅克尔憩室染成蓝色，而肠系膜和回肠未被染色。回肠动脉发出的无分支动脉及其远端的一组扩张迂曲血管提示可能存在梅克尔憩室，选择性动脉注射可证实这一诊断。应强调的是，血管造影即使在无急性出血的情况下也能检测出梅克尔憩室。
