Hepatic Artery Aneurysm: An Unusual Cause of Upper Gastrointestinal Bleed in 49 Years Old Patient

Hepatic artery aneurysm (HAA) is a rare disease. HAA is generally asymptomatic disease when symptomatic, they usually present with abdominal pain, upper gastrointestinal (GI) bleeding and/or jaundice, hypovolaemia secondary to rupture or GI bleeding with normal GI endoscopy. Surgical repair and endovascular treatment are the two therapeutic options available at present. Case report: A 49-year-old male presented at the emergency department with high gastrointestinal bleeding, abdominal pain and jaundice. Gastroscopy showed an ulcer with flat pigmented haematin on ulcer base (Forrest IIc) that was controlled by medical treatment. CT angiography was done and showed aneurysm of the proper hepatic artery almost totally thrombosed measuring 100 × 59 mm associated with signs of contained rupture. Emergency surgery was indicated. The laparotomy objectified a rupture of the aneurysm in the biliary tree in per operative excision of aneurysm and ligation of the hepatic pedicle was carried out. After surgery, the evolution was favorable with a follow-up of 8 months. Conclusion: HAA rupture is a rare cause of upper GI bleeding. The mortality rate after rupture is relatively high. CT angiography or MRI can diagnose a ruptured of HAA. Urgent surgery should be the first choice in patients with a ruptured HAA with active hemorrhage causing hemorrhagic shock.

Surgical repair of an emergent giant hepatic aneurysm with an abdominal aortic dissection:A case report

BACKGROUND Hepatic artery aneurysm(HAA)is the second most common visceral aneurysm.A significant number of hepatic aneurysms are found accidentally on examination.However,their natural history is characterized by their propensity to rupture,which is very serious and requires urgent treatment.An emergent giant hepatic aneurysm with an abdominal aortic dissection is less commonly reported.CASE SUMMARY We report the complicated case of a giant hepatic aneurysm with an abdominal aortic dissection.A 66-year-old female presented with the complaint of sudden upper abdominal pain accompanied by vomiting.Physical examination showed that her blood pressure was 214/113 mmHg.Her other vital signs were stable.Computed tomography found a giant hepatic proper aneurysm and dissection of the lower segment of the abdominal aorta.Furthermore,angiography showed a HAA with the maximum diameter of approximately 56 mm originating from the proper hepatic artery and located approximately 15 mm from the involved bifurcation of the left and right hepatic arteries with no collateral circulation.Therefore,we decided to use a stent to isolate the abdominal aortic dissection first,and then performed open repair.After the operation,the patient recovered well without complications,and her 3-month follow-up checkup did not reveal any late complications.CONCLUSION Open surgery is a proven method for treating giant hepatic aneurysms.If the patient's condition is complex,staged surgery is an option.

Nonclassical Cause of Obstructive Jaundice: A Case Report of Multiple Visceral Arterial Aneurysms in a Young Patient

Multiple visceral artery aneurysms are relatively rare;the rarest are superior mesenteric artery and gastroduodenal artery aneurysms. The clinical presentation depends on the size and site of the aneurysm. We report the case of a 33-year-old man with recurrent episodes of obstructive jaundice and weight loss. Computed tomography with contrast revealed scattered hepatic arterial aneurysms with two other aneurysms along the course of the left gastro-duodenal and superior mesenteric artery. Investigations to determine the etiology were negative, but the patient had a history of smoking and substance abuse. Angiography revealed an occluded feeding artery. The patient developed multiorgan failure, leading to cardiac arrest and died. Diagnosing multiple visceral artery aneurysms needs a high index of suspicion;early diagnosis enables early intervention, which can reduce the high mortality of this condition.
