We report a case of a ruptured aneurysm of the anomalous cerebellar artery originating from internal carotid artery presenting with a carotid cavernous fistula (CCF). An initial angiogram showed the typical appearance of a CCF with a direct fistulous tract with focal aneurysmal dilation from the ascending cavernous segment of the right internal carotid artery. A postembolization angiogram of th...

We performed simultaneous noninvasive measurements of common carotid artery and brachial artery hemodynamics in nine normal subjects and 10 subjects with sustained essential hypertension. In hypertensive subjects, brachial artery blood flow and forearm vascular resistance were in the normal range while carotid artery blood flow and carotid artery resistance were decreased and increased, respect...

Background and purpose Despite advances in endovascular therapies, some patients experience vertebral artery stenosis or subclavian occlusion may not benefit from less-invasive angioplasty/stenting. This study described 4 cases which carotid-vertebral transposition (CVT) carotid-subclavian (CST) was adapted when treatment unfeasible unsuccessful. Presentation Case 1: A 65-year-old woman present...

BACKGROUND In horses, the extracranial and intracranial pathway of the internal carotid artery has been described. The extracranial pathway of the internal carotid artery begins at the carotid termination and runs on the dorsal surface of the medial compartment of the guttural pouch. Thereafter the internal carotid artery passes through the foramen lacerum to continue intracranially, forming pa...

BACKGROUND Trifurcation of the common carotid artery is an unusual variation. CASE REPORT We report a case of left common carotid artery trifurcation in a 74-year-old man. The left common carotid artery divided into the internal carotid, external carotid and facial arteries. Herein, the anatomy of the carotid arteries and the Doppler sonography and CT angiography findings of the left common c...

We retrospectively studied 46 patients with symptomatic retinal artery occlusion and assessed the pattern and extent of carotid artery disease ipsilateral to the retinal artery occlusion. Ipsilateral internal carotid artery atherosclerotic lesions were virtually limited to the cervical arterial segment; 50% of such lesions were plaques or stenoses of less than or equal to 60%, whereas 15% of th...

Two main vascular routes supply the brain, internal carotid arteries (ICAs) and vertebral arteries. The external artery (ECA) mainly supplies skin, muscle, skull; thus, neurointerventionalists should be aware of ECA‐ICA, ECA‐vertebral artery, extracranial–intracranial anastomoses. These anastomoses are not newly formed but that remnants developmental processes. During development, ICA has with ...

OBJECTIVES To explore the possibility of pathological change in the common carotid artery at the bifurcation and in the internal carotid artery beyond the bifurcation which could contribute to a reduced diastolic pressure as observed in primary open angle glaucoma. DESIGN Duplex ultrasonic examinations of carotid bifurcations were conducted on 80 patients. Carotid artery defects were allocate...

Managing patients scheduled for cardiac surgery with significant carotid artery disease is a controversial issue that usually produces very polarized opinions, even in the literature. Discussion focuses on determining if carotid disease, concomitant with the need for coronary artery bypass, is an important etiologic factor for post-surgical stroke, or simply a marker of increased risk of vascul...
