Open Surgical Repair for a Giant Common Hepatic Artery Aneurysm with Difficulty in Proximal Arterial Clamping: A Case Report

Abstract

Hepatic artery aneurysm has been considered as a rare, life-threatening disease. In this study, we report on a patient requiring surgical treatment for a giant hepatic artery aneurysm by aneurysmectomy without revascularization. A 70-year-old woman who complained of epigastric pain was referred to our hospital. Enhanced computed tomography scan has revealed a giant (11×9 cm) common hepatic artery aneurysm. She then underwent emergency surgery; the intra-aortic balloon occlusion technique was applied in order to control the blood inflow into the aneurysm. The aneurysm was then incised, and direct closure of the inflow and outflow orifices was performed safely without evidence of ischemic change in the liver.

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.…”

Splenic artery transposition for reconstruction of a large hepatic artery aneurysm: A case report and literature review

“…Of these, we believe that the most important advantages of the splenic artery are the adjustable caliber difference and ability to secure sufficient distance. A PubMed search using the keywords “open surgery” and “hepatic artery aneurysm” revealed 15 cases of hepatic artery resection and reconstruction among 10 years from 2011 to 2021, including our own cases ( Table 1 ) [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] . Five cases had autologous arterial reconstruction and four of these five cases had splenic artery transposition.…”

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.…”
