Giant true hepatic aneurysm mimicking Mirizzi syndrome

Abstract

Giant true aneurysms of the hepatic arteries are rare. Pseudoaneurysms of the hepatic arteries are more common and are mostly caused by intra-abdominal infection, iatrogenic injury, or trauma. Hepatic or cystic pseudoaneurysms are often successfully treated by embolization owing to their saccular nature as opposed to true aneurysms. We present a case of a patient with a giant true aneurysm of the proper hepatic artery, mimicking Mirizzi syndrome. Open reconstruction was successfully preformed, and the patient made a full recovery.

Open surgical repair of a giant common hepatic artery pseudoaneurysm that perforated into the duodenum and common bile duct

“… 1 , 2 , 3 True HAAs exceeding 10 cm have been reported 11 times. 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 However, this is the first case documenting a giant, chronic pseudoaneurysm exceeding 10 cm in the CHA. Although most CHA pseudoaneurysms stem from traumatic or iatrogenic origins, no previous history of endovascular or open surgery, trauma, or infection was noted in this case.…”

Open surgical repair of giant hepatic artery aneurysm

“…Giant HAAs (>10 cm in diameter) are exceptionally rare with only a few documented cases in the literature. 6 , 7 , 9 , 10 , 11 , 12 , 13 , 14 , 8 , 15 , 16 Outcomes of giant HAAs in literature are reported in Table I . The management of giant HAAs remains an operative challenge owing to the significant risk of rupture and distortion of natural anatomy.…”
