# Lower Limb Ischemia Caused by Aortic Atherosclerosis Localized in the Horseshoe Renal Isthmus

## TL;DR

Aortic atherosclerosis in the horseshoe renal isthmus can cause lower limb ischemia and intermittent claudication.

## Contribution

Highlights a rare extrarenal vascular complication in patients with horseshoe kidneys.

## Key findings

- Sclerotic changes in the aorta due to renal isthmus compression may lead to lower limb ischemia.
- Vascular disease is an under-recognized complication in horseshoe kidney patients.

## Abstract

Intermittent claudication in patients with horseshoe kidneys may arise from sclerotic changes in the aorta due to compression by the renal isthmus. Vascular disease is a relatively lesser‐known extrarenal complication of horseshoe kidneys, but it warrants attention.
