<i>First Prize (Tie):</i> Hemorrhage Following Percutaneous Renal Surgery: Characterization of Angiographic Findings

Abstract

Major hemorrhage requiring intervention after percutaneous renal surgery is uncommon. The most common angiographic finding is arterial pseudoaneurysm, followed by arteriovenous fistula, and contrast extravasation. In 95% of cases angiography reveals a demonstrable and treatable etiology. This strongly supports the first-line use of angiography for intractable bleeding in this setting.
