PURPOSE Most intracranial dissecting aneurysms involve the posterior circulation, and the intradural segment of the vertebral artery is affected in majority of these. The aim of this report is to summarize the results of endovascular treatment in patients with ruptured dissecting aneurysms of the non-vertebral posterior circulation. MATERIALS AND METHODS During the past six years, the medical...

AIM This study aimed to investigate the microsurgical anatomy of perforating arteries in the hypothalamic area, which are associated with diabetes insipidus. MATERIAL AND METHODS A total of 20 adult cadaver heads soaked in formalin were infused with red latex through the carotid artery and vertebral artery, and supplementary perfusion was performed after 1 day. RESULTS The perforating arter...

A 5-year-old boy was referred to our hospital for evaluation of headache, tortuous intracranial arteries and vertebral arteries found up on brain magnetic resonance angiography. The patient’s family history was unremarkable for any genetic disease. He was born at 39 weeks of gestation by spontaneous vaginal delivery without complications. His birth weight was 3,580 gm. At 3 years Neurovascular ...

This paper describes the course and variation in the brain base arteries in fallow deer. The metrical features of the brain base arteries were determined with an image analysis system. The main sources of blood supply to the brain in fallow deer are internal carotid arteries; vertebral arteries rarely participate in blood supply. The brain base arteries in fallow deer show variation both in the...

The natural history of cerebrovascular disease (CBVD) was evaluated in 169 non-treated patients followed for at least 12 years after aortocervical angiography. The outcome was related to type and location of atherosclerotic changes in the neck vessels. At the time of angiography, 108 patients had completed strokes, 20 had transient ischemic attacks (TIAs), and 41 had angiography for reasons oth...

vertebrobasilar insufficiency is the cause of cerebrovascular accidents in 20% of cases. there are few reports regarding spectral doppler indices (sdis) of vertebral arteries (vas) normal blood flow. the objective of this study was to provide basic reference data about sdis of vas normal blood flow separately and in comparison with internal carotid arteries (icas) and common carotid arteries (c...

Concerning the structure of connective-muscular components the authors studied the walls of the terminal segments of the vertebral arteries as well as the basilar artery, utilizing the following staining methods: Azan modified by Heidenheim, Weigert's resorcin-fuchsin, and Weigert modified by van Gieson. It was established that wall of the vertebro-basilar system exhibits a mixed structure, mus...

The Vertebral Artery Each vertebral artery enters the foramen magnum in front of the roots of the hypoglossal nerve, inclines forwards and medially to the anterior aspect of the medulla oblongata and unites with its fellow at the lower border of the pons to form the basilar artery. The posterior inferior cerebellar and the anterior spinal arteries are its principal branches and it sometimes giv...

Ultrasound examination of the extracranial carotid and vertebral arteries has been used for many years to diagnose and manage patients with cerebrovascular disease. However, evaluation of the intracranial circulation has until now required angiography. Extracranial ultrasound examinations utilize probe frequencies ranging from 3 to 10 MHz. These frequencies are unable to penetrate bone sufficie...

T his is a case of a 47-year-old German lorry driver with very limited English who presented with sudden onset of a neck pain followed by an occipital headache while he was on the motorway. The pain forced him to stop his vehicle and call a friend who brought him to accident and emergency department. On examination, he had unsteady gait, slight dysarthria and subtle horizontal nystagmus on extr...
