Giant Splenic Artery Pseudoaneurysm Presenting with Acute Kidney Injury / 대한내과학회지

ABSTRACT

Splenic artery pseudoaneurysm is a rare, but potentially lethal, vascular lesion. The mortality rate may be 75-90%, if the aneurysm ruptures. The risk for rupture of an untreated splenic artery pseudoaneurysm is about 37%. Hence, early diagnosis and prompt surgical intervention are vital to improve survival. However, vague symptoms make early diagnosis difficult. We report here a case of a giant splenic artery pseudoaneurysm presenting with acute kidney injury. The patient had been treated previously for infective endocarditis, and after 4 months, acute kidney injury developed. Imaging studies revealed a giant splenic artery pseudoaneurysm. Splenectomy and distal pancreatectomy were performed. After surgery, renal function was improved.
