[Percutaneous transluminal angioplasty of the branches of the aortic arch]
Insights
Percutaneous transluminal angioplasty (PTA) is effective for treating blocked arteries in the brain and upper limbs. When properly indicated, PTA is a safe procedure for these critical arteries, with no complications observed in this study.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Obliterating arterial diseases require effective therapeutic interventions.
- Percutaneous transluminal angioplasty (PTA) has become a standard treatment option.
- The application of PTA is expanding into new areas.
Purpose of the Study:
- To evaluate the experience and outcomes of PTA in arteries supplying the brain and upper extremities.
- To assess the safety and efficacy of PTA in specific arterial locations.
Main Methods:
- Retrospective analysis of PTA procedures performed on 31 arteries in 29 patients.
- Focus on PTA of the subclavian artery, vertebral artery, and internal carotid artery.
- Evaluation of PTA for atherosclerotic strictures, fibromuscular dysplasia, and post-endarterectomy restenosis.
Main Results:
- PTA of the subclavian artery is considered a primary treatment method.
- Angioplasty of the vertebral artery carries a low risk when appropriately indicated.
- PTA is advantageous for internal carotid artery stenosis due to fibromuscular dysplasia and some early restenoses post-endarterectomy.
- PTA is not recommended for atherosclerotic strictures of the internal carotid artery due to embolism risk from ulcerated plaques.
- No complications were reported in the study group.
Conclusions:
- Percutaneous transluminal angioplasty is a safe and effective method for treating arterial diseases in the brain and upper extremities when correctly indicated.
- The study highlights the specific indications and contraindications for PTA in these vascular territories.
Abstract:
Percutaneous transluminal angioplasty (PTA) takes its stable position in the therapy of obliterating arterial diseases. Its indication areas considerably extend. The authors present a survey of their experience and the results of PTA of arteries supplying the brain and upper extremities. This surgery was made in 29 patients on 31 arteries. The authors consider PTA on a. subclavia as a method of choice. In the angioplasty on a. vertebralis there is a very low risk in correctly indicated cases. An atherosclerotic stricture of a. carotis interna is not considered suitable for PTA for the risk of embolism from the exulcerated plaques. However, the method may be used with advantage in the stenosis based on fibromuscular dysplasia and in some cases of early restenoses in a. carotis interna after previous endarterectomy. The authors arrive at the conclusion that PTA, if correctly indicated, is a safe method even in arteries supplying the brain and upper extremities. No complication was observed in the reported group.
