PURPOSE To describe the vascular and nonvascular intracranial and extracranial anomalies associated with hemangiomas and vascular malformations of the face, neck, and/or chest. METHODS Seventeen patients had a physical examination and imaging studies consisting of one or more of the following: pneumoencephalography, conventional carotid and vertebral arteriography, CT, MR imaging, and MR angi...

OBJECTIVES To describe clinical-radiologic characteristics in a prospective series of patients having both confirmed reversible cerebral vasoconstriction syndrome (RCVS) and cervical artery dissection (CeAD). METHODS From January 2004 to December 2011, from our prospective cohorts of RCVS and CeAD, we studied patients with both conditions. RESULTS Of 173 RCVS cases and 285 CeAD cases, 20 pa...

BACKGROUND Anatomic variety and difficult accessibility of the vertebrobasilar arteries pose considerable problems to conventional ultrasound. We evaluated the diagnostic potential of transcranial color-coded sonography in the distal part of this system. METHODS We insonated the intracranial section of the vertebrobasilar arteries through the foramen magnum window in 24 healthy individuals us...

General and isolated cervical positional tests are used to screen for potential vertebro-basilar insufficiency (VBI). There is limited research evaluating vertebral artery blood flow in these positions to justify the rationale of progressive mechanical stress occurring to the arteries. The purpose of the study was to determine vertebral artery blood flow in six cervical positions used in clinic...

CASE REPORT A 78-year-old man experienced 2 short-lasting episodes of vertigo with unstable gait during the 5 days before admission. One week previously, he had carried large fiberboard panels, involving sustained rotation of the neck in both directions. His past medical history included arterial hypertension and dyslipidemia. The initial general and neurologic examination was normal except for...

Methods: This descriptive cross-sectional study evaluated the anatomical characteristics of the cerebellar arteries and their branches in 93 brain stem and cerebellum blocks obtained from fresh cadavers. The specimens were perfused bilaterally channeling the proximal segments of the internal carotid and vertebral arteries with a semi-synthetic resin (Palatal GP40L 85%; styrene 15%) impregnated ...

OBJECTIVES To study the prevalence of degenerative changes in the arteries supplying the cervicobrachial region, and their relation to cervical disc degeneration. METHODS Fifty postmortem aortic arch angiographies were evaluated for occlusions and variations in the diameter of the vertebral arteries and thyro- and costocervical trunks, as well as for tortuosity, average diameter and the highe...

BACKGROUND AND PURPOSE We performed the present study to determine whether the site of occlusion in the vertebrobasilar circulation could be identified by the measurement of blood flow velocity in the bilateral vertebral arteries. METHODS Using color-coded duplex carotid ultrasonography, we measured the time-averaged mean and end-diastolic flow velocities with incident angle correction in 130...

AIM To examine a possible relationship between the variable vascular geometry of vertebrobasilar joint angle and basilar bifurcation angle as well as the diameters of these blood vessels. METHODS The study included 60 adult patients, of both sexes, who were divided into two groups. One group (30) consisted of patients without aneurysm of vertebrobasilar tree, and another group (30) of patient...

Carotid arterial dissections may result from spontaneous or traumatic causes. Postcoital arterial dissections have been reported in both the vertebral and coronary arteries. We report a rare case of spontaneous dissection from the common carotid artery to the internal and external carotid arteries after sexual intercourse, leading to fulminant middle cerebral artery (MCA) territory infarct. Alt...
