Anatomical Variations of Vertebral Artery
Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...
متن کاملDiagnosis and management of vertebral artery stenosis.
Introduction Approximately one-quarter of ischaemic strokes involve the posterior or vertebrobasilar circulation. 1,2 Stenosis of the vertebral artery can occur in either its extra-or intracranial portions, and may account for up to 20% of posterior circulation ischaemic strokes. 3–6 Stenotic lesions, particularly at the origin of the vertebral artery, are not uncommon. In an angiographic study...
متن کاملNoninvasive angiography for the diagnosis of vertebral artery disease using Doppler ultrasound (vertebral artery Doppler).
A transoral noninvasive procedure in the oropharynx using local anesthesia was applied to detect flow in the vertebral arteries with a bidirectional continuous-wave Doppler ultrasound system. Common carotid artery compression was used to identify the vertebral artery. Flow direction, amplitude of flow signals, diastolic flow, and reaction of flow on common carotid artery compression served as d...
متن کاملVertebral Artery Thrombosis in Chronic Idiopathic Thrombocytopenic Purpura
INTRODUCTION Immune thrombocytopenic purpura (ITP) is an autoimmune hematological disorder that causes decreased production and destruction of platelets leading to thrombocytopenia. Although thrombocytopenia usually causes hemorrhagic problems, thrombotic events like strokes, although rare, can still occur. Management of thrombotic events in patients with ITP differs from that of patients with ...
متن کاملAngiographic diagnosis of small aneurysms of the posterior communicating artery.
Angiographic diagnosis of an aneurysm of the internal carotidposterior communicating arteries (ICA-PCoA) is usually straightforward [1 ], unless the aneurysm is small (< 5 mm) or the PCoA itself is not filled on carotid angiography. In the latter case, the aneurysm may be confused with an infundibulum. In 1964, Fox et al. [2 , 3] described five patients with subarachnoid hemorrhage, three of wh...
