Insights
Endovascular treatment using stents effectively manages aortoiliac artery obstructive lesions, offering high patency rates. Regular follow-up and reintervention can improve long-term outcomes for patients with claudication and other symptoms.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Interventions
Background:
- Aortoiliac artery obstructive lesions are a significant cause of lower limb ischemia.
- Endovascular treatment offers a less invasive alternative to open surgical repair.
- Stent implantation and transluminal angioplasty are key endovascular techniques.
Purpose of the Study:
- To evaluate the three-year experience with endovascular treatment of aortoiliac artery obstructive lesions.
- To assess the efficacy and long-term outcomes of stent implantation.
- To determine the role of follow-up and reintervention in maintaining stent patency.
Main Methods:
- A retrospective review of 57 patients (61 limbs) undergoing endovascular treatment for aortoiliac lesions.
- Stent implantation and transluminal angioplasty were utilized.
- Patients were followed clinically and with duplex ultrasound at 3 months and 6 months intervals.
Main Results:
- Immediate angiographic success was achieved in all cases.
- Primary patency rates were 92% at 1 year, 88% at 2 years, and 86% at 3 years.
- Cumulative primary assisted patency was 98% with a mean follow-up of 15.8 months.
Conclusions:
- Endovascular treatment with stents is a safe and effective option for aortoiliac artery obstructive lesions.
- Regular clinical and ultrasound follow-up can detect asymptomatic in-stent stenosis.
- Percutaneous reinterventions can significantly improve long-term stent patency and patient outcomes.
Abstract:
The authors summarised their three year experience with endovascular treatment of the aortoiliac artery obstructive lesions using stents and transluminal angioplasty. Fifty-seven patients (61 limbs) underwent stent implantation to treat claudications (n = 50 limbs), rest pain (n = 6), non-healing defects (n = 4) and one patient was asymptomatic (n = 1). After stent placement patients were followed-up using clinical and duplex ultrasound examinations at 3 months and 6 months thereafter. Immediate angiographic success was achieved in all cases. Three serious complications were observed. Percutaneous reinterventions because of stenosis inside the stent were performed in 7 patients (7 limbs). The primary patency rates were 92% at 1 year, 88% at 2 years and 86% at 3 years. Cumulative primary assisted patency were 98% (mean follow-up 15.8 months, range 3-47 months). Regular clinical and ultrasound follow-up examinations can reveal the asymptomatic instent stenosis and percutaneous reinterventions can improve long-term stent patency.
