Left gastric artery pseudo-aneurysm post sleeve gastrectomy: A case report

Abstract

Highlights Bleeding in the context of sleeve gastrectomy could be caused by a variety of diseases. Pseudo-aneurysm is an overlooked complication. Angiography followed by embolization is best for diagnosing and treating. Common risk factors for pseudo-aneurysm include, infection, trauma, neoplasm, inflammation and surgery. Treatment was surgical, this case was treated by interventional radiology.

“…Treatment of visceral pseudoaneurysm has evolved greatly. Previously, surgical interventions such as aneurysmectomy or ligation were used but fell out of favor due to high mortality and complication rates [ 2 , 4 ]. Transarterial embolization is now preferred due to the ability to more precisely localize the lesion and assess collateral flow [4] .…”

“…Visceral pseudoaneurysms are a rare complication of infection, trauma, neoplasm, inflammation, and surgery [2] . Visceral pseudoaneurysms most commonly involve the splenic (60%), hepatic (20%), superior mesenteric (5.5%), celiac (4%), gastric and gastroepiploic (4%), intestinal (3%), pancreaticoduodenal and pancreatic (2%), and gastroduodenal (1.5%) arteries [3] .…”
