title: [Intracranial (arterial and venous) and carotid hemodynamics in patients with severe pulmonary pathology].
abstract: A distinctive feature of cerebral blood circulation in patients with chronic non-specific lung diseases (CNLD) complicated with chronic pulmonary heart (CPH) is a pronounced disturbance of cerebral venous drainage without a reliable reduction of both cerebral circulation and blood flow in common carotid arteries. Correlation between the degree of venous drainage disturbance and an extent of CNLD was found. Atherosclerotic damage of major arteries of the head in patients with ischemic stroke (IS) and CNLD was less marked. A comparative comprehensive study of the state of cerebral circulation was performed in two groups of patients. Predominance of the disturbance of venous outflow was found in the patients with IS and CNLD. The volumetric blood flow reduction prevailed in a group of patients with IS due to carotid occlusion. There was no significant difference in local cerebral circulation between the two groups. Obviously the disturbance of venous outflow causes the decrease of cerebral blood circulation in patients with CNLD, therefore "venous stroke" is possible in some patients with CNLD. Poor prognosis of IS in patients with CNLD and CPH is registered. It is stated that venous drainage disturbance and volumetric blood flow reduction in common carotids are main factors affecting progress and outcome of IS.
