Microsurgical treatment of ophthalmic segment aneurysms of internal carotid artery: 28 cases report

Objective To investigate the operative modalities and outcomes of 28 cases of ophthalmic segment aneurysms of internal carotid artery. Methods Twenty-eight cases of ophthalmic segment aneurysms of internal carotid artery were operated on from May 2004 to August 2009. Of all 28cases, 20 were large or giant. Nineteen aneurysms were directly clipped or resected with internal carotid artery revascularization. Since 2006, high-flow extracranial-intracranial (EC-IC)bypass were available and performed in 9 patients of large or giant aneurysms and then the aneurysms were resected or trapped. Results Seventeen patients underwent digital subtraction angiography (DSA), computed tomography angiography (CTA) or magnetic resonance angiography (MRA) postoperatively. The images demonstrated that 5 grafts of bypass were in patency, and 2 were occluded. Only 1 aneurysm was partially clipped and the others disappeared on imaging. The 78% of these cases had good results( GOS 4-5). One patient died after EC-IC bypass due to neck hematoma. Conclusions The treatment of ophthalmic segment aneurysms of internal carotid artery, especially the large and giant ones, remains a challenge for neurovascular neurosurgeon. The accessorial high-flow EC-IC bypass procedures and selection of suitable aneurysm clips are very important to improve the effectiveness of the operation.
