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.
在对72只狗进行的实验中，通过用肠线完全或部分结扎血管、用涂有MK-6胶水的波浪形肠线夹完全或部分封闭静脉腔，研究了后腔静脉壁形态学变化的特点，这些操作会导致血管内血流暂时紊乱。已证明，在静脉血流暂时紊乱时，采用软夹闭以预防肺动脉血栓栓塞具有优势。在进行软夹闭时，血管受压部位仍有部分血流，管腔内不形成血栓，静脉内不存在粗糙的营养不良性和坏死性改变，从而确保了静脉器官的保存。1.5个月后血管腔完全恢复，受压部位的静脉壁结构与正常无异。
