Selective celiac and superior mesenteric arteriographies were performed in patients with portal hypertension. An arterioarterial (A-A) shunt between the superior mesenteric artery and the celiac axis via pancreatic arcades was found in fifteen of forty-three patients with associated massive splenomegaly. A mild A-A shunt disappeared after portacaval anastomosis alone, whereas a prominent A-A shunt was reduced but persisted. The persisting A-A shunt disappeared after splenectomy. These findings led us to suggest that the paucity of the blood flow in the common hepatic artery concomitant with increased splenic arterial flow to the massively enlarged spleen may result in a compensatory supply to the liver from the superior mesenteric artery via the shunt.
对门静脉高压患者进行了选择性腹腔动脉和肠系膜上动脉造影。在43例伴有巨大脾肿大的患者中，有15例发现肠系膜上动脉与腹腔干之间通过胰腺动脉弓形成动-动脉（A-A）分流。单纯门腔静脉吻合术后，轻度A-A分流消失，而显著的A-A分流虽有所减少但仍持续存在。脾切除术后，持续存在的A-A分流消失。这些发现使我们认为，肝总动脉血流减少，同时流向巨大脾脏的脾动脉血流增加，可能导致肠系膜上动脉通过分流为肝脏提供代偿性供血。
