[Structural and histochemical characteristics of different variants of the perimuscularization of the femoral vein in an experiment].
Structural and histochemical changes in the region of perivenous muscular constrictors created by means of experimental perimuscularization of the femoral vein were studied and compared. Thirty-two mongrel dogs were operated on. In 18 dogs, perimuscularization was made by placing the femoral vein beneath a flap from the medial head of the musculus quadriceps femoris. In 14 dogs, the proximal segment of the dissected femoral vein was introduced through a tunnel formed in the medial head of the musculus quadriceps femoris followed by restoration of the vein continuity by an angiography apparatus. It has been shown that the method of the femoral vein introduction through the muscular tunnel is very promising, since it results in minimal histostructural changes in the vessel and the adjacent muscle.
