# Acute thrombotic occlusion of a profunda femoris artery aneurysm

## TL;DR

A rare case of a profunda femoris artery aneurysm caused acute thigh pain due to blood clotting, successfully treated with surgery.

## Contribution

This paper presents a novel case report of thrombotic occlusion in a profunda femoris artery aneurysm and its successful surgical management.

## Key findings

- Contrast-enhanced CT showed complete thrombosis of the profunda femoris artery aneurysm and partial thrombus in the superficial femoral artery.
- Elective surgery including ligation and graft replacement resolved the issue with good postoperative outcomes.
- Follow-up imaging confirmed graft patency and preserved thigh blood flow.

## Abstract

A profunda femoris artery aneurysm (PFAA) is an extremely rare peripheral arterial lesion, often first detected following rupture or swelling of the groin or thigh region. We report a 74-year-old man who presented with acute thigh pain caused by thrombotic occlusion of a left PFAA associated with a common femoral artery aneurysm (CFAA). Contrast-enhanced computed tomography at presentation demonstrated complete left PFAA thrombosis and partial thrombus formation within the left superficial femoral artery. The aneurysms’ diameters were 30 mm for the left CFAA and 35 mm for the left PFAA. The patient’s symptoms stabilized after systemic heparinization. Considering the recurrent thrombosis and potential aneurysmal rupture risks, an elective surgical intervention was performed. This procedure consisted of PFAA ligation, prosthetic graft replacement of the CFAA, and lateral circumflex femoral artery branch reconstruction. The patient’s postoperative course was uneventful, and follow-up imaging confirmed excellent graft patency and preserved thigh perfusion.
