Carotid arterial dissections may result from spontaneous or traumatic causes. Postcoital arterial dissections have been reported in both the vertebral and coronary arteries. We report a rare case of spontaneous dissection from the common carotid artery to the internal and external carotid arteries after sexual intercourse, leading to fulminant middle cerebral artery (MCA) territory infarct. Alt...
We report herein the usefulness of a manual external carotid artery manipulation for failed advancement of devices through the stent in carotid artery stent (CAS) placement with open cell type stent and filter type distal protection device. In all, 22 consecutive patients underwent CAS with filter type protection device between April 2008 and December 2009 in our institution, and failed advance...
A 21-year-old man was admitted to our hospital in December 1986, with exophthalmos, conjunctival injection, mild abducens palsy, mild retrobulbar pain , and bruit on the right. Digital subtraction angiography (DSA) revealed a dural AVM of the right cavernous sinus portion fed by meningeal branches of the right internal carotid artery (Fig. 1 A) and external carotid artery. The superior ophthalm...
Numerous anatomic variants of the internal and external carotid arteries have been described [1-6]. We report on an unusual variant of external carotid artery anatomy in which no identifiable main external carotid trunk was present, and thus no true carotid bifurcation existed . The bifurcation as it existed was reduced to anomalous branching of a common facial-lingual trunk. Marked atheroscler...
BACKGROUND AND PURPOSE The vascular supply of extra-axial brain tumors provided by the external carotid artery has not been studied with RPI. The purpose of this work was to determine whether RPI assessment is feasible and provides information on the vascular supply of hypervascular extra-axial brain tumors. MATERIALS AND METHODS Conventional ASL and RPI studies were performed at 3T in 8 cons...
We report a case of a 79-year-old man presenting with left cervical carotid artery stenosis associated with non-bifurcating cervical carotid artery, a very rare congenital anatomical variation supplying different branches of the external carotid artery directly from a common trunk without a bifurcation. We performed carotid endarterectomy for this symptomatic carotid artery atherosclerotic sten...
