[Scintigraphic and electrocardiographic changes after ligation of the pulmonary artery, pulmonary veins and mixed ligation in dogs].

The authors have investigated in 6 dogs the disturbances of the perfusion determined by ligature of the main left pulmonary artery, of the pulmonary veins, and mixed ligatures. The scintigraphic method was used (consisting in intravenous injection of radionuclide-labelled ferric colloids, and detection with the Anger camera). In 12 dogs electrocardiographic modifications were also investigated, occuring at various intervals of time after the above-mentioned ligatures. With the aid of scintigraphy it was noted that pulmonary perfusion was abolished in the corresponding lung both immediately and at 24 hours following ligatures. With the aid of scintigraphy it was noted that pulmonary perfusion was abolished in the corresponding lung both immediately and at 24 hours following ligature of the vessels. The same aspects was noted in all three types of ligature. Consecutive infarctions were noted at necropsies. The electrocardiogram evidenced sings of coronary failure when all the pulmonary veins of one lung were ligatured, signs of ventricular and atrial overcharge in dogs with ligature of the pulmonary artery and mixed modifications, although less severe, in combined vascular ligatures. The more rapid evolution toward death of dogs with ligatures of the pulmonary veins could be explained by the coronary failure.

[Contribution of pulmonary scintiscanning to the diagnosis of chronic obstructive bronchopneumopathy].

In a lot of 32 cases of chronic obstructive bronchopneumopathy, a correlation was established between the extent and location of the regional perfusion deficiencies (studied by scintigraphy) and overall functional disturbances Vmax MEVS X 100VC, residual volume, R, PaO2, PaCO2). In 85% of the cases regional perfusion disturbances were detected and grouped into six scintigraphic types. A good correlation was found between these disturbances and the MEVS X 100/VC index and modified partial pressure of the gases (O2, CO2) in the arterial blood. Unexpected was the absence of a mathematical correlation between perfusion disturbances and the residual volume and R, suggesting the great variety of the disturbances grouped under the general denomination of chronic obstructive bronchopneumopathy.
