An anatomical and radioanatomical study of the intracranial branches of the occipital artery is presented and attempt to systematize the muscular branches of the occipital trunk and its vertebral anastomosis. An embryological hypothesis is presented to explain and memorize all the artrial variations of this area.
Identifying when past exposure to an infectious disease will protect against newly emerging strains is central to understanding the spread and the severity of epidemics, but the prediction of viral cross-protection remains an important unsolved problem. For foot-and-mouth disease virus (FMDV) research in particular, improved methods for predicting this… (More)
Following a review of the literature, the authors show that the posterior branch of the odontoid arch and the anterior meningeal artery are, in reality, the same vessel. Focusing attention on the metameric nature of the upper cervical spine and its blood supply makes a simplified approach to the pharyngovertebral anastomoses possible.
BACKGROUND Despite the enormous global burden of tuberculosis (TB), conventional approaches to diagnosis continue to rely on tests that have major drawbacks. The improvement of TB diagnostics relies, not only on good biomarkers, but also upon accurate detection methodologies. The 10-kDa culture filtrate protein (CFP-10) and the 6-kDa early secreted antigen… (More)
A case is presented in which three arterial stenoses and one arterial occlusion due to Takayasu's disease were treated by an endovascular approach. The endovascular technique is discussed, and the clinical and angiographic findings after treatment are correlated with cerebral hemodynamic and metabolic parameters as measured by positron emission tomography.
BACKGROUND Giant perimedullary arteriovenous fistulas (GPMAVFs) located in the cervical region are a rare pathology with distinctive characteristics. OBJECTIVE To evaluate clinical presentation and different endovascular treatment options of cervical GPMAVFs and review previously published data in the literature regarding cervical GPMAVFs. METHODS Six… (More)
INTRODUCTION Direct carotid artery puncture (DCP) is employed in patients with tortuous anatomy and peripheral vascular disease when the peripheral arteries are not available for vascular access. Manual compression is the only method of achieving hemostasis following DCP and, till date, the use of a closure device for DCP has been reported in only one… (More)
Intercavernous sinuses surround the pituitary gland and their form can be modified by small pituitary tumors. A preliminary report of the use of venography for the diagnosis of pituitary microadenomas is presented.
