Abstract:
Vertebral and basilar arteries are the major blood suppliers of the brain. They supply nearly one-third of the brain. Congenital absence of these arteries is a rare condition. Usually, this condition presents with stroke like presentation. This is a case presentation of a 40-year-old lady who was diagnosed as congenital agenesis of vertebra-basilar arteries. This lady was presented with intraventricular hemorrhage. Subsequently the diagnosis was made by cerebral angiogram.

Abstract Posterior circulation territory stroke following mild head injury is a known entity although rarely seen. Numerous case reports appear in literature from time to time highlighting this complication. Blunt trauma to the head and neck possibly causes injury to the vertebrobasilar system in the form of angiorrhexis, subintimal, intramural and perivascular hemorrhage which causes secondary narrowing of the injured vessel. These processes can be complicated by progressive thrombosis & vascular occlusion. Here we are reporting a case of post traumatic vertebra-basilar dissection causing

Abstract:
Introduction: Vertebral artery passes through vertebral artery groove present on the posterior arch of atlas; free movement of which is required during rotation of the neck. This artery can be compressed if the vertebral groove is converted into arcuate foramina due to the projection of bony ponticuli over the grove. This compression can cause vertebra-basilar insufficiency, headache, or neck-shoulder pain of unknown origin. Objective: This study aims to provide data regarding vertebral artery groove and its morphology to help surgeons and clinicians in the local Pakistani population as no dat

Abstract:
The article discusses cranio-cervical joints, specifically the atlanto-occipital and atlantoaxial joints. The atlanto-occipital joints include the occipital condyle and the superior articular surfaces of the first cervical vertebra (C1 or Atlas), allowing flexion, extension and lateral tilt of the head. The atlantoaxial joints include C1 and C2 (Axis) vertebrae, enabling rotation. Atlanto-occipital fusion is a rare congenital condition in which C1 fuses with the occipital bone of the skull. This can lead to narrowing of the Foramen Magnum, with or without compression of central structures (spi

Abstract BACKGROUND AND IMPORTANCE Congenital clefts and aplasias of the atlas vertebra are rare. A nonfused posterior arch occurs in 4% of the population; in contrast, a nonfused anterior arch occurs in only 0.1%. To the best of our knowledge, this is the first description of the combination of anterior arch aplasia and a cleft of the posterior arch of the atlas associated with Klippel-Feil and Treacher-Collins syndromes and Sprengel deformity.

This is a report of 3 relatively rare clinical cases in which the absence of posterior elements of the axis was associated with basilar invagination and multiple other craniovertebral junction musculoskeletal and neural abnormalities. Atlantoaxial fixation resulted in remarkable clinical recovery in all 3 cases. C2–3 fixation was not done, and bone decompression was not done. On the basis of their experience, the authors conclude that atlantoaxial fixation is a satisfactory form of surgical treatment in patients having an association of basilar invagination with absent posterior elements of ax

Stroke is the most common cause of neurological disability (MacDonald, Cockerell, Sander, &amp; Shorvon, 2000) and about 1 in 3 stroke life survivors are functionally reliant on it after one year (Murray and Lopez 1996). The majority of stroke survivors need restoration (MacDonald et al., 2000), requiring them to be adequately informed of the prognosis, nature, and proposed treatment of their illness. Hearing plays an important role in effective communication between healthcare professionals and patients (Bensing, 2000), therefore hearing loss may restrict contribution in recuperation programs

Abstract We report an exceptional case of a large right persistent proatlantal artery (PPPA), defined as a “mixed” type, because it originated as in Type 2 from the external carotid artery and courses as in Type1, i.e. over the vertebral artery groove of the posterior arch of C1, entering the skull via the foramen magnum, without passing through the transverse foramen of any of the cervical vertebra. This “mixed” PPPA was associated first with an azygos anterior cerebral artery and second with a left common carotid artery arising from the brachiocephalic trunk. The right occipital artery arose

One hundred thirty patients with ischemic strokes attributed to high-grade carotid stenoses (&gt;60%) were recruited for digital subtraction angiograms (DSA).
