Saphenous Vein Graft Aneurysm after Drug-Eluting Stent Implantation: Treatment by Covered Stent

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Vascular Medicine

Background:

• Saphenous vein graft aneurysms (SVGAs) are infrequent complications of coronary artery bypass grafting, associated with increased morbidity and mortality.
• Atherosclerosis is the primary cause, though infections and surgical factors also contribute.
• SVGAs often present incidentally as cardiac or mediastinal masses on radiography.

Observation:

• Symptomatic presentations include chest pain, dyspnea, and myocardial infarction.
• This report details a unique case of an SVGA developing after percutaneous intervention, a previously undescribed etiology.
• The patient's SVGA was successfully managed using a polytetrafluoroethylene (PTFE) covered stent.

Findings:

• The case represents the first documented instance of an SVGA arising subsequent to percutaneous intervention.
• Successful treatment was achieved with a PTFE-covered stent, demonstrating its efficacy in this rare scenario.

Implications:

• This case expands the known spectrum of SVGA development and management.
• It underscores the importance of considering SVGA in patients with prior interventions presenting with relevant symptoms or imaging findings.
• The successful use of covered stents offers a viable treatment option for this specific complication.
