Percutaneous transluminal angioplasty following endarterectomy
Insights
Endarterectomy and percutaneous transluminal angioplasty (PTA) can be used sequentially for recurrent arterial occlusive disease. These interventions are effective even when applied after prior procedures for iliac or subclavian artery stenosis.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Radiology
Background:
- Recurrent arterial occlusive disease poses a significant challenge after initial surgical interventions.
- Endarterectomy is a common procedure for arterial stenosis, but recurrence can necessitate further treatment.
- Noninvasive and arteriographic methods are crucial for diagnosing and monitoring recurrent stenosis.
Purpose of the Study:
- To evaluate the efficacy of sequential endarterectomy and percutaneous transluminal angioplasty (PTA) in managing recurrent arterial occlusive disease.
- To assess the feasibility of PTA after previous endarterectomy and vice versa for iliac and subclavian artery stenosis.
Main Methods:
- Retrospective review of 7 patients with recurrent arterial occlusive disease.
- Noninvasive vascular testing and arteriography for diagnosis.
- Interventions included endarterectomy and percutaneous transluminal angioplasty (PTA), sometimes multiple times.
Main Results:
- Seven patients with recurrent stenosis of iliac or subclavian arteries were treated. Procedures included PTA after endarterectomy, endarterectomy after PTA, and repeated interventions for recurrence.
- One patient required multiple endarterectomies and PTAs over 8 years for common iliac artery stenosis.
- Successful recanalization and dilatation were achieved, with some requiring repeat procedures due to recurrence.
Conclusions:
- Endarterectomy does not preclude subsequent PTA, and PTA does not preclude subsequent endarterectomy for recurrent arterial occlusive disease.
- Sequential application of these revascularization techniques can be effective in managing complex cases of recurrent arterial stenosis.
- These findings support a combined or sequential approach for patients with persistent or recurrent arterial occlusive disease.
Abstract:
Recurrent occlusive disease was found by noninvasive methods and confirmed arteriographically in 7 patients who had undergone endarterectomy for stenosis of one [5] or both iliac arteries [1] or the subclavian artery [1]. Three patients with iliac artery stenosis had percutaneous transluminal angioplasty (PTA) 1 to 5 years after endarterectomy. One patient with stenosis of the external iliac artery had PTA 4 years after endarterectomy, and dilatation was repeated 7 months later because of recurrence. One patient had 2 endarterectomies and 2 PTAs within 8 years for stenosis of the right common iliac artery. One patient had recanalization of the left common iliac artery 6 years after endarterectomy with low-dose streptokinase followed by PTA. Another patient underwent endarterectomy of the left subclavian artery 3 months after PTA and required further dilatation at 5 and 10 months because of recurrence. The authors conclude that endarterectomy does not preclude PTA (or vice versa) in patients with recurrent arterial occlusive disease.
