# Transcatheter Arterial Embolization for Blunt Trauma in a Horseshoe Kidney With Contralateral Renal Artery Anomaly: A Case Report and Literature Review

## TL;DR

A 23-year-old with a horseshoe kidney and rare blood vessel issue had a severe kidney injury from trauma, which was successfully treated with a minimally invasive procedure.

## Contribution

Highlights the successful use of TAE in a complex horseshoe kidney case with a rare vascular anomaly.

## Key findings

- TAE effectively controlled active arterial bleeding in a horseshoe kidney with a contralateral renal artery anomaly.
- Pre-procedural vascular evaluation is crucial for managing trauma in patients with complex renal anatomy.
- The patient recovered without complications following the emergency intervention.

## Abstract

Horseshoe kidney (HSK) is a common renal anomaly associated with an increased risk of traumatic injury due to its superficial location and frequent vascular anomalies. We report a case of a 23-year-old male patient with HSK and a rare vascular anomaly, a right renal artery originating from the left common iliac artery, who sustained a grade V renal injury following blunt trauma. Contrast-enhanced computed tomography (CT) revealed active arterial bleeding and a retroperitoneal hematoma. Emergency transcatheter arterial embolization (TAE) successfully controlled active bleeding. The patient recovered without complications. This case underscores the importance of pre-procedural vascular evaluation in HSKs, as well as the efficacy of TAE in managing severe renal injuries associated with complex vascular anatomy.
