Post-Traumatic Renal Artery Pseudoaneurysm Managed Successfully with Angioembolization

Renal artery pseudoaneurysm is a rare complication of blunt renal trauma. Super-selective angioembolization is aminimally invasive, effective procedure to manage traumatic renal artery pseudoaneurysm, in patients who are hemodynamicallystable. We report our experience in the management of patients with post-traumatic bleeding pseudoaneurysm withangioembolization. Materials and methods: We retrospectively reviewed the inpatient and outpatient records and imagingdata of our hospital, of all patients with history of blunt injury to kidneys, admitted with massive hematuria and underwentangioembolization to control the bleeding. Results: During the study period, 3 patients (all male) with a mean age of 26.66 yearspresented to us with blunt injury abdomen. Contrast computed tomography (CT) revealed Grade IV renal injury in 2 patientsand Grade V injury in 1 patient. Focal intensively enhancing areas were noted at the site of renal parenchymal lacerationssuggestive of pseudoaneurysms. Super-selective catheterization was performed and embolization done using 50% N-butyl-2-cyanoacrylate (NBCA) + Lipiodol. Conclusions: Angioembolization, a radiographic intervention, is an effective and minimallyinvasive technique to stop active bleeding from renal artery pseudoaneurysms.
