Anterior Wall Aneurysms of Internal Carotid Artery:

"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...

Patency of the anterior choroidal artery after flow-diversion treatment of internal carotid artery aneurysms.

BACKGROUND AND PURPOSE Treatment of cerebral aneurysms with flow diverters often mandates placement of the device across the ostia of major branches of the internal carotid artery. We determined the patency rates of the anterior choroidal artery after placement of flow-diversion devices across its ostium. MATERIALS AND METHODS We analyzed a consecutive series of patients in whom a Pipeline Em...

A Lumped Parameter Method to Calculate the Effect of Internal Carotid Artery Occlusion on Anterior Cerebral Artery Pressure Waveform

Background and Objective: Numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. One physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. In this study, we can predict hemodynamic behavior of one artery of circulatory system (...

A Penetrating Pellet Jeopardizing Internal Carotid Artery

Wall shear stress on ruptured and unruptured intracranial aneurysms at the internal carotid artery.

BACKGROUND AND PURPOSE Hemodynamics is often recognized as one of the major factors in aneurysm rupture. Flow impingement, greater pressure, and abnormal wall shear stress are all indications for aneurysm rupture. Characterizing wall shear stress for intracranial aneurysms at similar anatomic locations may help in understanding its role. MATERIALS AND METHODS Twenty-six intracranial aneurysms...
