Hemodynamics model of fluid–solid interaction in internal carotid artery aneurysms

"Kissing aneurysms" of the internal carotid artery.

Five patients with kissing aneurysms (adherent internal carotid-posterior communicating artery and ipsilateral internal carotid-anterior choroidal artery aneurysms) are reported. There was female predominance and the subarachnoid hemorrhage was commonly due to rupture of the proximal posterior communicating artery aneurysm. Despite the demonstration of angiographic cleavage, the two aneurysms a...

Hemodilution improves cerebral hemodynamics in internal carotid artery occlusion.

BACKGROUND AND PURPOSE Hemodilution may be a useful form of therapy for patients with carotid occlusive disease and hemodynamic ischemia. Accordingly, we evaluated the effects of hemodilution on cerebral hemodynamics and oxygen metabolism in patients with carotid artery occlusion. METHODS Using positron emission tomography, we analyzed regional cerebral blood flow, oxygen extraction fraction,...

Incidental Intracranial Aneurysms in Patients With Internal Carotid Artery Stenosis

Background and Purpose—Smoking and hypertension are important risk factors for atherosclerotic carotid artery disease, but also for intracranial aneurysms. We studied the presence of aneurysms in a series of patients with internal carotid artery (ICA) stenosis and performed a systematic review of the literature to assess in patients with ICA stenosis the prevalence of intracranial aneurysms, ge...

Aneurysms of the petrous portion of the internal carotid artery.

Aneurysms of the petrous portion of the internal carotid artery are rare lesions. One case is reported here and 18 others have been found in the literature. These lesions usually arise in young men who present with auditory dysfunction. The aneurysm is usually discovered as a pulsating purple mass in the middle ear and mistaken for a glomus jugulare tumor. A definitive diagnosis can be made by ...
