Infratentorial Tumors and the Dural Venous Sinuses

Raised intracranial pressure and cerebral blood flow: 3. Venous outflow tract pressures and vascular resistances in experimental intracranial hypertension

“…Some studies have shown little change in sagittal sinus pressure (Becht, 1920;Weed and Flexner, 1933), some have shown a decrease in sinus pressure (Wright, 1938;Bedford, 1942), while others have shown an increase in sagittal sinus pressure with increasing intracranial pressure (Dixon and Haliburton, 1914;Langfitt et al, 1966). Clinical measurements in acute intracranial hypertension and both clinical and experimental observations in chronic intracranial hypertension have also shown that sagittal sinus pressure may rise with increasing intracranial pressure (Shulman et al, 1964;Kinal, 1966;Osterholm, 1970). It seems probable that the pressure within the sagittal sinus reflects the sum of several variables including mechanical factors affecting sinus compressibility, the level of blood flow through the sinus, and the central venous pressure.…”

Langzeitmessung des Ventrikelliquordruckes bei intrakraniellen raumfordernden Prozessen und akuten Hirnschädigungen

“…Auf die Bedeutung venöser Abflußstörungen infolge direkter Kompression der Sinus transversus und sigmoideus haben Tönnis u. Schiefer (171 a) sowie Ki1Ul1 (85) hingewiesen. Phlebographische Untersuchungen ergaben, daß die Kompression der Sinus durch eine Beseitigung des raumfordernden Prozesses, hingegen weniger durch eine drastische Senkung des Liquordruckes, beseitigt werden kann (85).…”

Cranial Venous Outflow Obstruction and Pseudotumor Cerebri Syndrome

“…Kinal [83] performed sinography on 4 patients (age 7 months-15 years) who presented with evidence of a posterior fossa lesion. In all patients the lesions had resulted in obstructive hydrocephalus with raised pressure.…”
