Relationship between brain tissue pressure gradients and cerebral blood flow distribution studied in circumscribed vasogenic cerebral oedema.

The present experimental study was designed to examine the correlations between brain tissue pressures, pressure gradients and cerebral blood flow distribution associated with circumscribed cerebral vasogenic oedema. Following unilateral hemispheric cryogenic injury in 42 adult cats, brain tissue pressures increased as a function of time. Interhemispheric pressure gradients became most marked one hour after the cryogenic injury (3.9 mm Hg on average), gradually decreasing thereafter. Transtentorial pressure gradients developed within the first hour after the injury, and remained above 10 mm Hg. The dye injected into one carotid system by the "single dye passage" technique was redirected towards the contralateral hemisphere and also towards the subtentorial compartment, as brain tissue pressures increased. The shift in the flow-distribution of dye and blood was more pronounced in the posterior fossa structures. When intracranial tissue pressures exceeded 60 mm Hg almost no dye entered the cranial cavity. This accompanied the marked decrease in cerebral perfusion pressure.

The proatlantal intersegmental artery: a case report and review of the literature.

A case of the proatlantal intersegmental artery (PIA) arising from the external carotid artery (ECA) is presented. The PIA gave rise to the occipital artery, a finding which may support the hypothesis that the distal part of the occipital artery is derived from it. The possibility that the PIA of ECA origin might be a hypertrophied collateral occipital artery is also suggested. The importance of the anteropasterior view in differentiating the PIA of ECA origin from the first cervical intersegmental artery is stressed.

Radionuclide angiography of vascular lesions of the spinal cord. Its efficacy in selecting patients for spinal angiography.

Selective angiography of the spinal cord is essential for both definitive diagnosis and preoperative evaluation of vascular lesions of the spinal cord. However, the complexity of angiography precludes its use in evaluating every spinal cord lesion. Radionuclide angiography successfully demonstrated vascular lesions of the spinal cord in our two cases, one a hemangioblastoma and the other an arteriovenous malformation. Myelography had not been conclusive in either case. The value of radionuclide angiography as a screening test for vascular lesions of the cord is stressed.

Cerebral aneurysm induced by giant cell arteritis: a case report.

A rare case of giant cell arteritis inducing an aneurysmal dilatation in the peripheral branch of the middle cerebral artery was presented. The lesion was solitary and no extra-cerebral vasculature was involved. The literature of giant cell arteritis and of similar disorders involving the intracranial arteries was reviewed.
