# Post-renal Transplant Pseudoaneurysm With Renal Artery Stenosis: A Rare and Life-Threatening Complication

## TL;DR

A rare case of life-threatening pseudoaneurysm and artery stenosis after kidney transplant is reported, highlighting the importance of CT scans for accurate diagnosis.

## Contribution

Highlights the rare complication of pseudoaneurysm after renal transplant and the diagnostic value of CT scans.

## Key findings

- Ultrasound suggested renal artery stenosis and pseudoaneurysm in a post-transplant patient.
- CT scan confirmed the pseudoaneurysm and provided clearer diagnostic information.
- The case underscores the rarity and severity of this post-transplant complication.

## Abstract

This case report follows a 64-year-old male patient who underwent deceased-donor renal transplantation for end-stage renal disease secondary to chronic hypertension and type 2 diabetes mellitus. On presentation, he displayed signs of volume overload, significant weight and blood pressure increases, and minimal urine output. Initial ultrasound revealed elevated peak systolic velocity at the transplant kidney anastomotic site, suggesting post-transplant renal artery stenosis along with a larger-than-expected iliac artery concerning for pseudoaneurysm, later confirmed with subsequent CT scan findings. This case outlines the rare nature of pseudoaneurysm post-renal transplant and emphasizes the efficacy of CT as a tool for diagnosis when ultrasound findings are equivocal.
