Regional venous drainage of the human heart.
Blood samples obtained from the coronary sinus in man contain venous blood draining from left ventricular myocardium. It is believed by many investigators that coronary sinus blood in man is composed almost entirely of left ventricular efflux. That this is true in the canine heart is firmly established (Rayford et al., 1959). This principle has been widely accepted in the many studies which hav...
متن کاملVenous drainage in perimesencephalic hemorrhage.
BACKGROUND AND PURPOSE In perimesencephalic nonaneurysmal hemorrhage (PMH), subarachnoid blood accumulates around the midbrain. Clinical and radiological characteristics suggest a venous origin of PMH. We compared the venous drainage of the midbrain between patients with PMH and aneurysmal subarachnoid hemorrhage (aSAH) by means of computed tomography angiography (CTA). METHODS CTAs of 55 PMH...
متن کاملAnomalous pulmonary venous drainage.
Cases of drainage of the pulmonary veins into the right side of the heart have been well summarized by Brody (1942). He reported 38 cases of complete, and 68 cases of partial, drainage of the pulmonary veins into the right atrium or its tributaries. The purpose of this paper is to record a further case, and to summarize the cases not reported by Brody and those which have been reported during t...
متن کاملManual drainage of the zebrafish embryonic brain ventricles.
Cerebrospinal fluid (CSF) is a protein rich fluid contained within the brain ventricles. It is present during early vertebrate embryonic development and persists throughout life. Adult CSF is thought to cushion the brain, remove waste, and carry secreted molecules(1,2). In the adult and older embryo, the majority of CSF is made by the choroid plexus, a series of highly vascularized secretory re...
متن کاملThe craniocervical venous system in relation to cerebral venous drainage.
BACKGROUND AND PURPOSE Passing from the supine to the upright position favors cerebral venous outflow into vertebral venous systems rather than into the internal jugular veins. We sought to determine venous connections between dural venous sinuses of the posterior cranial fossa and craniocervical vertebral venous systems. METHODS Corrosion casts of the cranial and cervical venous system were ...
