[Morphologic and surgical indications for temporary partial occlusion of the inferior vena cava by soft clipping].
In the experiment performed on 72 dogs peculiarities of morphological changes in the posterior vena cava wall have been studied at a temporal disturbance of blood flow in it by means of a complete or partial ligation of the vessel with catgut, a complete or partial closing of the lumen of the vein by means of a wavy catgut clip, covered with glue MK-6. Predominance of the soft clipping at the temporal disturbance of the blood flow in the vein with the aim of prophylaxis of thromboembolism of the pulmonary artery has been demonstrated. At the soft clipping in the place of the vascular compression, the blood flow partially remains, thrombi in the lumen do not form, rough dystrophic and necrotic changes in the vein are absent, that is the organ preservation of the vein is ensured. In 1.5 months the vascular lumen is completely restored, and structure of its wall at the place of compression does not differ from the normal one.
