# Aberrant Left Testicular Artery Originating from the Inferior Mesenteric Artery Identified on Angiography in a Patient with Gastrointestinal Bleeding: Case Report

## TL;DR

A rare case of a left testicular artery branching from the inferior mesenteric artery is reported, highlighting its clinical importance for endovascular procedures.

## Contribution

This case adds to the limited literature on a rare vascular anomaly involving the testicular artery's origin.

## Key findings

- The left testicular artery originated from the inferior mesenteric artery in an 89-year-old male.
- The superior rectal artery was absent from the inferior mesenteric artery in this patient.

## Abstract

Background and Clinical Significance: This case presents a rare variation in mesenteric and pelvic vasculature that holds relevance for endovascular procedures. Limited published cases of the testicular artery arising off the inferior mesenteric artery exist in the literature and play an important role in clinical outcomes. Case Presentation: An 89-year-old male presented with gastrointestinal bleeding from diverticulosis. During an arteriogram to locate and assess sigmoid arteries for embolization, an unusual anatomical variant of the left testicular artery was discovered. Typically, the left testicular artery originates from the abdominal aorta below the renal arteries. However, in this patient, the left testicular artery was found to directly branch off the inferior mesenteric artery, while the superior rectal artery was absent from the inferior mesenteric artery. Conclusions: Awareness of such vascular variations is essential for interventionalists to optimize procedural success and minimize complications. Recognizing potential vascular anomalies, such as those presented in this case, is essential for effective pre-procedural planning and intraoperative management to improve patient outcomes.
