Abstract

This article reports a 49-year-old male with an isolated deep femoral artery aneurysm (DFAA) successfully treated by endovascular stent-graft (Solaris®) deployment and branch embolization. One-year follow-up confirmed stent patency without endoleak. This case provides a minimally invasive option for rare DFAA.

Introduction

Isolated DFAA accounts for only 0.5% of peripheral aneurysms but carries a 55% rupture risk. Open surgery is invasive, while endovascular techniques offer a promising alternative. This study combines case experience and literature review to evaluate technical strategies.

Case Study

A patient presented with right thigh pain and a pulsatile mass. Duplex and CT angiography revealed a 6-cm DFAA. Endovascular treatment included:

Branch Embolization: Azur® coils (2×4mm, 6×10mm, etc.) were deployed to occlude proximal branches, preventing type II endoleak.

Stent-Graft Placement: A 9×100mm Solaris® covered stent (Scitech Medical, Brazil) was implanted, followed by post-dilation with a 9×80mm Oceanus balloon. The patient was discharged on dual antiplatelet therapy. At 1-year follow-up, the stent remained patent without complications.

Conclusions

1.Endovascular therapy effectively excludes aneurysms and reduces rupture risk.

2.Branch embolization is critical for endoleak prevention, requiring anatomical customization.

3.The Solaris® stent’s flexibility and instant sealing are ideal for deep femoral artery anatomy.
