[Compensatory and adaptive changes in the heart after pulmonary resection (morphometric analysis)].
The experiment has been performed in 124 non-inbred dogs by means of a complex of morphometrical methods in order to study compensatory-adaptive processes in the heart after pulmonary resection various in its volume. After 58% resection, and especially after 67-75% resection of the lung mass, a stable pulmonary arterial hypertension appears; it results in development of a chronic cor pulmonale and terminates in its decompensation. Application of extrapulmonary arterio-venous anastomosis, before 67-75% of the pulmonary parenchyma is resected, decreases hypertension in the pulmonary circulation, improves adaptive changes of the heart in the newly formed conditions of hemodynamics, preventing development of its failure.
