Summary
Kissing stent insertion effectively treats aortic bifurcation stenosis, improving limb ischemia symptoms in 95% of patients. This minimally invasive approach offers a safer alternative to surgery with few adverse events.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Medical Devices
Background:
- Aortic bifurcation stenosis poses significant risks with traditional surgery (3% mortality) and balloon angioplasty (9% complication rate).
- Kissing stent insertion is a novel technique aiming to reduce complications associated with treating aortoiliac occlusive disease.
Purpose of the Study:
- To evaluate the safety and efficacy of simultaneously delivered kissing stents for treating aortic bifurcation stenosis.
- To assess the impact of kissing stent insertion on symptoms of lower limb ischemia.
Main Methods:
- Twenty patients with symptomatic lower limb ischemia and significant atherosclerotic lesions in the aortic bifurcation underwent simultaneous kissing stent insertion.
- Palmaz stents were deployed bilaterally into the iliac arteries to treat ostial or complex single-ostial stenoses.
Main Results:
- The kissing stent procedure was successful in all 20 patients with no acute complications.
- Significant reduction in stenosis was observed in the iliac arteries and distal aorta (P < .001).
- Symptomatic improvement occurred in 95% of patients, with 63% becoming asymptomatic; preprocedural femoropopliteal disease severity predicted outcomes (P = .02).
Conclusions:
- Kissing stent insertion is an effective and safe treatment for aortic bifurcation stenosis.
- This technique offers a promising alternative for patients with aortoiliac occlusive disease, leading to substantial symptom relief.
