Insights
Stenting chronic iliac artery occlusions without thrombolysis effectively restored blood flow, improving ankle-arm index and pressure gradients. This endovascular approach successfully eliminated symptoms and avoided bypass surgery in all patients.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Endovascular Therapy
Context:
- Chronic iliac artery occlusion presents a significant challenge in vascular disease management.
- Traditional treatment often involves bypass surgery, which carries substantial risks.
- Endovascular techniques offer a less invasive alternative for treating arterial occlusive disease.
Purpose:
- To evaluate the efficacy and safety of primary intra-arterial stent placement without thrombolytic therapy for chronic iliac artery occlusions.
- To assess the functional improvement in patients undergoing stent implantation for iliac artery occlusion.
Summary:
- Four patients with chronic iliac artery occlusions (lesion length 2.0–14.0 cm) underwent intra-arterial stent placement (Wall, Strecker, Palmaz stents).
- The mean ankle-arm index improved from 0.48 to 0.77, and the mean pressure gradient decreased from 82.5 mmHg to 3.0 mmHg.
- All patients experienced symptom resolution with no major procedural complications.
Impact:
- Primary stent implantation is a viable and effective strategy for managing chronic iliac artery occlusions.
- This endovascular approach can successfully avoid the need for bypass surgery.
- The procedure demonstrates significant functional improvement and symptom relief in patients with iliac occlusive disease.
Abstract:
Intra-arterial stent placement without thrombolytic therapy was performed in four patients with chronic iliac arterial occlusion. The length of angiographically observed occluded lesions ranged from 2.0 cm to 14.0 cm (mean: 5.1 cm). The implanted stents included four Wall stents, two Strecker stents and one Palmaz stent. The mean ankle-arm index before and after stenting improved from 0.48 to 0.77, while the mean pressure gradient improved from 82.5 mmHg to 3.0 mmHg. Symptoms were eliminated in all patients after the procedure. No major complications were encountered during the procedure. Primary stent implantation in chronic iliac occlusions is useful to avoid bypass surgery.
