Leaking hepatic artery aneurysm successfully treated with covered stent

Abstract

Hepatic artery aneurysm (HAA) is rare with reported incidence of 0.02%. It accounts for approximately 12-20% of all visceral aneurysms. The reported risk of rupture ranges from 14% to 80% of all HAAs. Traditionally, HAA has been treated surgically or by transcatheter coil embolization. There are few published reports of percutaneous HAA stenting. We report a case of a 72-year-old female with leaking HAA who was successfully treated with endovascular stenting. The authors include a review of the relevant literature.

Splenic Artery Transposition Graft Usage for the Supply of the Right Hepatic Artery: A Case Report

“…1,5,8,9 Among the different forms of splanchnic vascular aneurysms, 1,2,4,8-10 only splenic artery aneurysms (60%-75%) are more frequent than HAA. Pseudoaneurysms of hepatic arteries in particular have been increasing in recent decades, and the rate of increase has paralleled the increase in interventional biliary procedures, such as biopsies, and nonoperative liver trauma (such as that caused by car accidents).…”

“…2,3,5,9 It has been reported that extrahepatic aneurysms are located in the common hepatic artery in 63% of reported cases, in the right hepatic artery in 28% of cases, in the left hepatic artery in 5% of cases, and in both the right and left hepatic arteries in 4% of cases. [3][4][5]8,10 Furthermore, a general trend has been noted in which intrahepatic aneurysms tend to be located in the right hepatic artery. 4 The aneurysmal diameters reported have ranged between 1.5 and 14 cm, with the mean diameter being calculated at 3.6 cm.…”

“…4 The aneurysmal diameters reported have ranged between 1.5 and 14 cm, with the mean diameter being calculated at 3.6 cm. 9 HAAs are solitary in 92% of cases and multiple in 8% of cases, 2,[8][9][10] and about one third of HAA patients present with other visceral artery aneurysms. 3,5,8,10 Although HAA has been diagnosed in all age groups and both sexes, most patients are adults (age range, 20-80 years) and male.…”

“…9 HAAs are solitary in 92% of cases and multiple in 8% of cases, 2,[8][9][10] and about one third of HAA patients present with other visceral artery aneurysms. 3,5,8,10 Although HAA has been diagnosed in all age groups and both sexes, most patients are adults (age range, 20-80 years) and male. 1,2,8,10 The exact etiology of HAA remains to be elucidated, and the ratio of possible risk factors has certainly changed during the past century.…”

“…1,5,7 Embolization, percutaneous transluminal angioplasty/stenting, or surgical repair is widely applied, whereas another less frequent option is excision with splenic artery transposition graft. [1][2][3][4][5][6][7][8][9][10] Here, we present a case of hepatic artery aneurysm that was successfully repaired with splenic artery transposition graft.…”
