– To clarify the central nervous and the cardiovascular mechanisms mediating the Cushing response (CR) during intracranial hypertension, the effects of continuous and prolonged expansion of an epidural supratentorial balloon was studied in six dogs

An experimental study was carried out in eight dogs to investigate whether the Cushing response (CR) during intracranial hypertension is due to pressure per se, tissue distortion, or ischemia in the brain stem. To minimize the effects of rostrocaudal

Epidural bleeding was produced in 8 anaesthetised and heparinised dogs by an artificial system. Changes in vital physiological variables were related to intracranial shifts and tissue water content assessed with MR imaging. Six animals survived while

A porcine model for an acute lethal arterial subdural bleeding in man is presented. Blood from the abdominal aorta was led via an electronic drop recorder into a collapsed intracranial subdural rubber balloon. Systemic arterial pressure (SAP), two in

Continuous recording of vital physiological variables and sequential MR imaging were performed simultaneously during continuous expansion of an epidural rubber balloon over the left hemisphere in anaesthetised dogs. Balloon expansion led to a progres

Cerebral haemodynamics were evaluated after a period of cerebral compression produced by subarachnoid fluid infusion or inflation of an epidural balloon. Release of the compression resulted in a marked cerebral hyperperfusion which was generalized in

Regional cerebral blood flow (rCBF) was studied during an aggressive epidural bleed, using a ventilated swine model. rCBF, regional organ blood flow and cardiac output were measured using the radioactive microsphere technique. Blood flows were measur

This study retrospectively analyzes the CT findings of 50 patients with spontaneous intracerebral haematomas and correlates them with the clinical condition at admission and the outcome. The volume of the haematoma was well correlated with the outcom
