Abstract

Cavernous carotid artery aneurysms (CCAs) represent a unique subset of intracranial aneurysms due to their distinct natural history and the anatomy of the cavernous sinus. Enlarging CCAs can cause elastic compression of the parent internal carotid artery (ICA). We suggest defining aneurysms that cause luminal stenosis of their parent vessels as 'matricidal aneurysms.'Though many patients are asymptomatic, presenting symptoms of CCAs include ophthalmoplegia with resulting diplopia, vision changes, pain, ptosis, facial numbness, and cavernous-carotid fistula. Less commonly, patients with CCAs can present with epistaxis, subarachnoid hemorrhage, and-in cases of matricidal aneurysms-ischemia due to stenosis. The proper management of stenosis caused by a matricidal CCA is not well established and may not be intuitive. We present a multicenter retrospective case series of patients with matricidal CCAs. Forty patients with matricidal aneurysms presented with both asymptomatic and symptomatic stenosis. These patients were either treated with conservative medical management, coiling, flow diversion, or endovascular sacrifice of the parent artery. Planned treatment modalities were not executed in 11 cases (28% treatment failure rate). Pr...Continue Reading
