Endovascular treatment of pseudoaneurysms secondary to chronic pancreatitis: reports of two cases

Tratamento endovascular de pseudoaneurisma decorrente de pancreatite crônica: relato de dois casos

Abstract

Pseudoaneurysm secondary to chronic pancreatitis is a rare complication, but one with a high mortality rate. It is etiologically associated with chronic pancreatitis, and most diagnoses are made after rupture, which manifests with clinical signs of acute hemorrhage. Computed tomography plays an important role in diagnosis, but digital subtraction angiography remains the gold-standard method for diagnostic confirmation and for treatment planning. This article describes two cases of pseudoaneurysm in patients with chronic alcoholic pancreatitis; one involving the splenic artery and the other the gastroduodenal artery, complicated by thoracic and abdominal bleeding respectively. Both were successfully treated, using minimally invasive endovascular methods to implant coils and stent-grafts.
