OBJECTIVE Thoracic and thoracoabdominal aortic repair are still complicated by spinal cord ischemia and paraplegia. The aim of the present article is to present the results of an anatomical study conducted by means of both postmortem injection of the vertebral artery and perfusion of the abdominal aorta. METHODS The spinal cord blood supply was investigated in 51 Caucasian cadavers: in 40 cas...

UNLABELLED Craniovertebral anomalies are rare causes of vertebral artery dissection. Therefore, appropriate evaluation is necessary in vertebrobasilar strokes, specially in the young. This is particularly true for patients with vertebral stroke without risk factors. RESULTS Here we report a 24-year-old male presenting with posterior circulation infarcts. The patient had no obvious vascular ri...

BACKGROUND AND PURPOSE Subarachnoid hemorrhage frequently leads to long-term cerebral artery narrowing called vasospasm. Very early changes in cerebral arteries have not been studied extensively and may be critical for the later pathological developments. We therefore determined what changes in the reactivity of cerebral arteries could be observed after 10 minutes' or 24 hours' contact with sub...

AIM Injury to the vascular supply to the cervical spinal cord can lead to the anterior spinal artery syndrome, which is often associated with transforaminal corticosteroid injections to the cervical foramina. The purpose of this cadaveric study was to examine the morphology of the cervical arteries and to emphasize their clinical importance. MATERIAL AND METHODS Five formalin-fixed human cada...

BACKGROUND AND PURPOSE Optimal estimation of cerebral blood-flow volume (BFV) may be an important indicator for better evaluation of the patients with cerebrovascular disorders. In this study, we compared the BFV values at bilateral internal carotid and vertebral arteries of healthy volunteers obtained with color Doppler, power Doppler, and B-flow ultrasound (US) studies and tried to determine ...

A housewife hanged herself with her left foot on a washstand and her right foot above the floor. The ligature mark encircled once horizontally at the height of the laryngeal prominence (horizontal part), crossed at the front of the neck, rose to the posterior regions of the mandibular angles and extended upward to the preauricular regions (ascending part). Petechial haemorrhage was in the conju...

In this brief article we describe the role of compression of the vertebral subclavian arteries, internal mammary, internal carotid arteries, brachial plexus and coiling and kinking of the vertebral and basilar arteries, the faulty irrigation of blood supply and oxygen of the cerebellum and basal ganglia of the brain. Among the effects are: a decrease in the secretion of dopamine at the level of...

BACKGROUND There are few studies for evaluating wall characteristics of intracranial vertebral artery hypoplasia (VAH). The aim of this study was to determine wall characteristics of VAH with three-dimensional volumetric isotropic turbo spin echo acquisition (3D VISTA) images and differentiate between acquired atherosclerotic stenosis and VAH. METHODS Thirty patients with suspicious VAH by lu...

BACKGROUND AND PURPOSE A pulsatility index (PI) represents vascular resistance distal to an examined artery. The purpose of the present study was to evaluate an association between plasma total homocysteine (tHcy) and PIs of the cerebral arteries in patients with ischemic stroke. METHODS Consecutive patients with ischemic stroke referred to a neurovascular ultrasound laboratory were evaluated...
