Description
A rare extra artery in the belly developed a weak, bulging spot in a sixty-two-year-old man, and the bulge then leaked into a major vein. Islam Elhelf and co-authors report his care in this 2026 case study. The artery, called the Arc of Buhler, directly links two large gut arteries and is present in few people. Bulges on it are rare, and a false bulge, or pseudoaneurysm, is rarer still.
The leak formed an abnormal channel between the bulge and the portal vein, which carries blood to the liver. Surgeons, vessel specialists who work through catheters, and imaging doctors planned the fix together. Part of the work was done from inside the vessel, and part by open surgery. The authors say no prior case joins these two faults. The case shows why rare anatomy needs a team approach.
