Cerebral venous circulatory system evaluation by ultrasonography.
Venous system can be classified as pulmonary veins, systemic veins and venous sinuses that are present only within the skull. Cerebral venous system is divided into two main parts, the superficial and the deep system. The main assignment of veins is to carry away deoxygenated blood and other maleficient materials from the tissues towards the heart. Veins have thinner walls and larger lumina tha...
متن کاملCerebral circulatory effects of acutely induced hypervolemia in human subjects.
• Hemodynamie alterations incident to acute changes in intravaseular volume have been extensively investigated in man as well as in animals. From these studies have emerged well-defined concepts of the responses elicited by acute reductions in blood volume. On the other hand, studies of the effects of expansion of the intravascular volume have yielded no clear hemodynamie sequence whereby the c...
متن کاملEvaluation of cerebral pathologic changes and long-term behavioral disorder after deep hypothermic circulatory arrest in dogs.
The purpose of this study is to evaluate the extent of brain damage following deep hypothermic circulatory arrest (DHCA), using behavior and pathological findings. The dogs underwent 60, 90 or 120 min of DHCA. After 72 h or 6 months, their cerebrum pathological findings were examined. No neurological deficit was found in any of the dogs. After 72 h, hippocampus cells (CA1) were TUNEL positive i...
متن کاملCerebral blood flow immediately following brief circulatory stasis.
Cerebral blood flow was studied in rabbits immediately following complete circulatory stasis of varying duration. Systemic arterial pressure was measured continuously. The postischemic circulation was examined both by an infusion of carbon black and, in separate experiments, by injection of 14C-antipyrine into the blood. We examined the relationship between the duration of stasis, the postische...
متن کاملCerebral circulatory and metabolic changes associated with aging.
The widespread prevalence of vascular disease among the aged has led to major consideration of the role of the circulation in the pathogenesis of human aging. Since many of the most prominent clinical features of old age are attributable to changes in the central nervous system, studies of the cerebral circulation and metabolism in the aged have enjoyed considerable popularity in recent years (...
