چکیده

Imaging of vascular structures and blood flow with magnetic resonance (MR) has added a new dimension in evaluating patients with suspected intracranial circulatory disturbances [1]. By using appropriate MR pulse sequences, the capability now exists of diagnosing intracranial circulatory abnormalities without the injection of radiographic contrast agents. We report a case of internal carotid artery occlusion initially diagnosed by MR.

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 (...

Carotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion

Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...

Long-term 3T MR angiography follow-up after therapeutic occlusion of the internal carotid artery to detect possible de novo aneurysm formation.

BACKGROUND AND PURPOSE The purpose of this study was to assess the incidence of de novo aneurysm formation, the incidence of subarachnoid hemorrhage (SAH), and the growth of existing untreated aneurysms in 52 patients after therapeutic carotid artery balloon occlusion for carotid aneurysms. PATIENTS AND METHODS Between January 1996 and August 2004, 52 patients were treated with carotid artery...

Internal carotid artery occlusion due to idiopathic cranial pachymeningitis.

A 35-year-old black woman had a 6-month history of headaches and a 1-month history of abducens nerve palsy. MR showed a mass in the sella and cavernous sinuses with encasement of the carotid artery. The mass enhanced intensely and homogeneously with Gd-DTPA. Arteriography revealed complete occlusion of the left internal carotid artery and severe stenosis of the C5 and C6 segments of the right i...

Routine MR imaging of the internal carotid artery siphone: angiographic correlation with cervical carotid lesions.

This study correlates the appearance of the cavernous segment of the carotid artery on MR images with the presence of significant stenosis or occlusion of the cervical carotid artery as seen on angiograms in 100 patients who had brain MR imaging and arteriography within a 1-week period. Four patients demonstrated isointense signal within the carotid artery's cavernous segment; two of these find...
