A quick fix: graft rescue for iatrogenic pseudoaneurysm

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Medical Device Technology

Background:

• Femoro-popliteal saphenous vein bypass grafts are used to treat peripheral artery disease.
• Stent-supported angioplasty is a common intervention for graft stenosis.
• Delayed graft rupture is a rare but serious complication.

Observation:

• A case of delayed rupture of a femoro-popliteal saphenous vein bypass graft occurred after stent-supported angioplasty.
• This resulted in a large, severely symptomatic pseudoaneurysm in the thigh.
• The pseudoaneurysm significantly impacted patient mobility and quality of life.

Findings:

• The pseudoaneurysm was successfully treated with the endovascular deployment of a covered stent graft.
• This minimally invasive approach achieved hemostasis and resolved symptoms.
• The study discusses potential mechanisms for pseudoaneurysm formation in this context.

Implications:

• Covered stent grafts represent a viable endovascular option for managing complex pseudoaneurysms in bypass grafts.
• Understanding rupture mechanisms can inform preventative strategies and patient selection for interventions.
• This case contributes to the literature on endovascular management of graft complications.
