Abstract
The cavernous aneurysms represent 3-11% of all intracranial aneurysms and about 14% of the internal carotid artery aneurysms. They represent a low risk of progressing to spontaneous subarachnoid hemorrhage, but can produce symptoms of compression to the cranial nerves, with the onset of retro-orbital pain or changes in the extrinsic ocular motility. The diagnostic investigation of these lesions consists of computed tomography, magnetic resonance imaging and cerebral angiography.The indication for treatment is questionable when symptoms are stable and well tolerated, especially in elderly patients. However, interventional treatment is indicated for patients with progressive neurological symptoms such as intense pain, and ruptured aneurysms. The ideal treatment is to exclude the aneurysm from the circulation, with preservation of the patency of the artery. However, the most widespread treatment is the occlusion of the internal carotid artery after undergoing carotid occlusion test. The purpose of this article is to critically review the literature regarding the carotid cavernous aneurysms, with special focus on therapeutic modalities available today.
