Artery Arising from the Internal Carotid Artery I read with interest the article by Chan et al. They stated that there was a rare congenital anastomosis between the vertebral artery (VA) and internal carotid artery (ICA) with an absence of communication between the common carotid and cervical ICA. I, however, diagnose that there was an acquired occlusion of the ICA at its origin with a developm...

Ophthalmoplegia is defined as a consequence of multiple cranial nerve paralysis innervated the extraocular muscles. The impairment ophthalmic branch trigeminal will create painful condition. Numerous underlying mechanism have been proposed related to ophthalmoplegia and carotid-cavernous fistula one main causes with sight life threatening outcome if left untreated. Carotid-cavernous arises an a...

A carotid cavernous fistula is an abnormal communication between the internal carotid artery and the cavernous sinus. Rarely, this communication is associated with a persistent primitive trigeminal artery, with or without a trigeminal artery aneurysm. We report a case of spontaneous carotid-trigeminal cavernous fistula in which the persistent trigeminal artery was shown only on vertebral artery...

This study was intended to correlate 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 37 patients with cerebrovascular disorders who had brain MRI and arteriography. Three patients demonstrated an isointense signal within the carotid artery's cavernous segment...

This report deals with a patient of 86 who developed a carotid-cavernous fistula. Artificial embolization alone was considered the safest treatment for this patient and proved to be adequate. Post-operative preservation of the patency of the internal carotid artery was demonstrated by angiography. We believe this method is particularly appropriate for carotid-cavernous fistulas if it is demonst...

A 42-year-old man presented with right temporal headache, dysarthria, and dysphagia. On examination, he had a right hypoglossal nerve palsy. The diagnosis of right internal carotid artery dissection was suggested by magnetic resonance imaging and confirmed by carotid angiography. A dynamic computed tomogram demonstrated enlargement of the carotid artery. In carotid dissection, the hypoglossal n...

The indications for carotid endarterectomy are sometimes imprecise. Total occlusion of the internal carotid artery has often implied irreversibility. Carotid thromboendarterectomy was performed on eight patients who on angiography had a complete occlusion of proximal internal carotid artery but showed antegrade opacification of the infraophthalmic carotid siphon. Direct magnification, delayed r...

A 21-year-old woman presented with an unruptured large intracavernous aneurysm, which was spontaneously revascularized via unusual collateral pathways a short time after extracranial-intracranial bypass and surgical ligation of the proximal internal carotid artery. The patient had been treated for a large basilar trunk aneurysm with intraaneurysmal embolization using Guglielmi detachable coils,...

BACKGROUND Local pulse pressure (PP) is an independent determinant of carotid artery wall thickness, stronger than mean blood pressure (BP). The present study was designed to assess whether a beta-adrenoceptor antagonist-based or an ACE inhibitor-based treatment was able to reduce carotid artery wall hypertrophy through a reduction in carotid PP rather than by lowering mean BP and whether the i...
