Selective visceral angiography findings.(a): Angiography of a celiac artery (CA) with balloon occlusion of SMA. There were no direct branches from the CA to the pancreas. (b): Angiography of a left gastric artery (LGA), which originated from the aorta directly, under balloon occlusion of CMT. Collateral circulation from the LGA to splenic artery (SA) via the short gastric artery (SGA) and from the LGA to the proper hepatic artery (PHA) via the right gastric artery (RGA) were observed. (c): Angiography findings of the CMT. Under local anesthesia, selective visceral angiography was performed using the bilateral femoral arteries approach. The size of the angiographic catheter was 4 Fr, and a 5 Fr balloon catheter (Selecon MP Catheter -II, Terumo Clinical Supply) was used. The Artis zee (Siemens) angiographic system was used, with ‘Press Duo’ the injection system (Nemoto Kyorindo Co., Ltd, Japan)
