Transvascular treatment of giant aneurysms of the cavernous carotid and vertebral arteries: Functional investigation and embolization

摘要: Abstract Functional angiographic investigation and percutaneous embolization using detachable balloons in nine carotid cavernous aneurysms, three petrous one vertebral artery aneurysm, posterior inferior cerebellar aneurysm are reported. A double-lumen balloon catheter is used to evaluate acute tolerance occlusion of the or arteries. Occlusion tested under systemic heparinization. Local perfusion heparinized saline, proximal as well distal, used. The procedure was successful all but aneurysm. arterial lumen sacrificed cases. Clinical improvement occurred Retroorbital pain relieved all. Ocular cranial nerve palsies improved resolved most. One delayed ophthalmic episode that represents only complication. No such embolic problems any case which occluded by trapping. complications after related collateral vessels C-4 C-5 segments artery. Balloon trapping decreases length thrombosed segment prevents retrograde filling
