Percutaneous transluminal angioplasty. Results and surgical implications

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Endovascular Procedures

Background:

• Percutaneous transluminal angioplasty (PTA) is a minimally invasive endovascular technique used to open narrowed or blocked arteries.
• Vascular disease management often involves complex surgical interventions, with varying success rates and complication profiles.

Purpose of the Study:

• To evaluate the long-term outcomes and safety of percutaneous transluminal angioplasty (PTA) in patients with peripheral arterial disease.
• To compare the efficacy of PTA in different arterial segments (iliac vs. femoropopliteal).
• To assess the role of PTA as an adjunct to traditional vascular surgery.

Main Methods:

• Retrospective analysis of 91 percutaneous transluminal angioplasty procedures in 80 patients.
• Life-table analysis was used to determine patency rates over a 36-month follow-up period.
• Factors influencing success rates, including predilatation ankle-brachial index, diabetes, rest pain, necrosis, and age, were analyzed.

Main Results:

• Overall 36-month patency rate was 46%.
• Success rates were lower in patients with ankle-brachial ratios < 0.45, diabetes, rest pain/necrosis, and older age.
• Iliac angioplasty (58% success) outperformed femoropopliteal angioplasty (18% success).
• Complication rate was low (4% required surgery).
• Combination of iliac angioplasty with bypass grafting achieved >85% long-term patency.

Conclusions:

• Percutaneous transluminal angioplasty (PTA) demonstrates moderate long-term patency and a low complication rate, making it a viable option for select vascular patients.
• PTA is particularly effective for iliac artery interventions and significantly enhances outcomes when combined with bypass surgery.
• Vascular surgeons should consider PTA as both an alternative and an adjunct therapy for managing peripheral arterial disease.
