Summary
A novel technique for treating ophthalmic artery aneurysms uses suction decompression via the external carotid artery, reducing risks associated with traditional methods. This approach minimizes internal carotid artery dissection and embolization for safer aneurysm management.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Interventional Neurology
Background:
- Ophthalmic segment carotid artery aneurysms present significant surgical challenges.
- The Batjer and Samson technique involves direct needle aspiration from the internal carotid artery, risking dissection and embolization.
- Existing methods for treating these aneurysms carry inherent risks.
Purpose of the Study:
- To present a modified suction decompression technique for paraclinoid aneurysms.
- To leverage the anatomy of the carotid bifurcation for aneurysm treatment.
- To reduce the risks of arterial dissection and distal embolization.
Main Methods:
- A revised suction decompression technique was developed utilizing the carotid bifurcation.
- The common and external carotid arteries were isolated, bypassing direct internal carotid artery manipulation.
- Aneurysm decompression was achieved via the external carotid artery, with aspirated blood saved for autotransfusion.
Main Results:
- The technique was successfully applied in two elderly patients.
- Good clinical outcomes were achieved in both cases.
- The revised method demonstrated feasibility and efficacy.
Conclusions:
- This modified technique effectively decompresses paraclinoid aneurysms.
- It avoids direct dissection of the internal carotid artery.
- The risk of distal embolization is significantly minimized, offering a safer alternative.
