Abstract

The hearts of 11 necropsy cases--nine with myocardial infarction and two with pulmonary embolia were investigated--histologically, histochemically and roentgenoangiographically. The author recommends, for the complete investigation of myocardium blood circulation, a successive filling of the heart vascular system, first of all with Indian ink-gel mass--for to follow up the microcirculation state and then--with roentgen-contrast mixture of Hauch and Tolgskaja--for to establish the changes in the large arterial vessels. Severe microcirculation disorders in the cardiac muscle were found in acute myocardial infarction, involving all heart segments, manifested with focal phenomena of stasis with ischemic changes in myofibres. With the establishment of a similar microcirculatory picture in pulmonary embolia, the author explains the differential-diagnostic difficultes in those two states. The thromb-formation in small arterial and venous vessels in those regions, developing on the background of a blood stasis with a consequent hypoxy of the vessel wall is stressed to be of importance for the intensification of the changes in the ischemic zone and for the widening of the necrotic area in case of fresh myocardial infarction. These obser...Continue Reading

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.
