The use of the Wallstent in aorto-iliac vascular disease
Insights
Self-expanding Wallstents effectively treated severe aorto-iliac arterial disease in 43 patients. This endovascular stenting procedure improved symptoms in all patients after six months, demonstrating cost-effectiveness.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Therapy
Background:
- Aorto-iliac arterial disease significantly impacts patient morbidity.
- Endovascular stenting offers a minimally invasive treatment option.
- Wallstents are a type of self-expanding stent used in vascular interventions.
Purpose of the Study:
- To evaluate the safety and efficacy of endovascular Wallstent placement for aorto-iliac arterial disease.
- To assess patient outcomes and complication rates following the procedure.
Main Methods:
- A cohort of 43 patients with severe aorto-iliac disease received self-expanding endovascular Wallstents.
- The study included various conditions such as iliac occlusions, severe atheromatous disease, dissections, and re-stenosis.
- A total of 59 Wallstents were deployed in 50 iliac arteries.
Main Results:
- All stents were successfully deployed without immediate failure.
- Five significant complications occurred, with four managed percutaneously and one requiring surgical embolectomy.
- At six-month follow-up, all patients reported symptomatic improvement.
Conclusions:
- Endovascular Wallstent insertion is a safe and effective treatment for selected cases of severe aorto-iliac arterial disease.
- The procedure leads to significant symptomatic improvement in patients.
- Aorto-iliac stenting presents a cost-effective therapeutic option.
Abstract:
Forty-three patients had self-expanding endovascular Wallstents inserted for aorto-iliac arterial disease. A total of 59 Wallstents were inserted into 50 iliac arteries. There were 27 males and 16 females with a mean age of 62.51 years. Included in the series were 19 iliac occlusions, 21 severe atheromatous disease of the aortoiliac segment, two severe dissections following conventional angioplasty and one re-stenosis of a previously dilated iliac segment. All of the stents were successfully deployed but there were five significant complications. One case of distal embolism was treated by surgical embolectomy but the other four were treated by an additional percutaneous technique. At follow-up after 6 months all patients remain symptomatically improved. Aorto-iliac stenting is a cost-effective treatment in selected cases of severe aorto-iliac disease.
