We report magnetic resonance (MR) angiographic evidence of congenital kinking of the internal carotid artery in 4-year-old twin brothers. The first twin presented with a left pulsating laterocervical mass '2 cm in diameter. On examination, the mass had a palpable thrill and a systolic murmur. An echo-Doppler examination showed a loop of the left internal carotid artery with no hemodynamic chang...

We prospectively studied the results of carotid angiography in 45 patients with transient or nondisabling neurologic deficits caused by lacunar infarction in the internal capsule or corona radiata and demonstrated by computed tomography. An ipsilateral stenosis at the bifurcation of the internal carotid artery was found in 14 patients (31%, 95% confidence limits 18-47%), seven of whom also had ...

AANA Journal/June 2007/Vol. 75, No. 3 193 Carotid endarterectomy is a procedure used to treat severe atherosclerotic occlusive disease involving the internal carotid arteries, most often at the common carotid artery bifurcation. The operation is performed by opening the common carotid arteries and the proximal internal carotid arteries in the neck, removing plaques from the inside of the arteri...

Paraclinoid internal carotid artery aneurysms originate from the internal carotid artery between the distal dural ring and the posterior communicating artery. Surgical treatment of these aneurysms is technically challenging because of the surrounding neurovascular structures. There are several ways to treat these lesions: direct clipping with retrograde suction decompression, endovascular coili...

Background and Purpose—Tandem internal carotid and middle cerebral artery occlusion independently predicts poor outcome after intravenous thrombolysis. Recanalization of internal carotid artery dissection by stent-assisted angioplasty has recently been proposed when anticoagulation fails to prevent a new ischemic event. We recently reported a case of tandem internal carotid and middle cerebral ...

OBJECTIVE Surgical resection of complex glomus vagale tumors can be complicated by extensive blood loss and might require surgical sacrifice of an encased internal carotid artery. METHODS A young patient presented with mass effect from glomus valage tumor. Computerized tomography angiography showed an encased internal carotid artery. Cerebral angiography demonstrated a highly vascular tumor....

BACKGROUND AND PURPOSE Tandem internal carotid and middle cerebral artery occlusion independently predicts poor outcome after intravenous thrombolysis. Recanalization of internal carotid artery dissection by stent-assisted angioplasty has recently been proposed when anticoagulation fails to prevent a new ischemic event. We recently reported a case of tandem internal carotid and middle cerebral ...

During the routine dissection of the neck region of a 77 years old male cadaver in the Department of Anatomy at Bankura Sammilani Medical College, a unilateral variation in the position and course of internal and external carotid arteries was noticed on the right side of neck. The internal carotid artery was anteromedial to the external carotid artery at the site of bifurcation of the common ca...

Alternative to carotid endarterectomy, carotid artery stenting (CAS) can be performed for symptomatic severe stenosis of internal carotid artery, especially for high-risk patients. Among several complications after CAS, subacute in-stent thrombosis is rare but important, because patient's condition can deteriorate rapidly. Subacute in-stent thrombosis with carotid artery occlusion can be manage...

A 40-year-old woman presented with symptoms compatible with Raeder syndrome. MR demonstrated narrowing of the left cavernous carotid artery. The high cervical portion of the left internal carotid artery was not identified. Angiography confirmed the narrowing of the cavernous carotid artery and showed marked and irregular stenosis of the distal cervical internal carotid artery. Involvement of th...
