Changes in hemodynamics of tibial diaphysis in case of blood flow disorder in superficial femoral artery

Changes in tibial hemodynamics have been studied experimentally after applying a clamp (n=41) and resection of superficial femoral artery (n=22) in 63 adult dogs.

Summary:Changes in tibial hemodynamics have been studied experimentally after applying a clamp (n=41) and resection of superficial femoral artery (n=22) in 63 adult dogs. It has been revealed with the help ofrheovasography that, in case of blood flow disorders in the superficial femoral artery, anastomoses with deep femoral artery branches contribute to maintenance of blood circulation in tibia, and in this connection the parameters of tibial blood flow may significantly differe from those of circulation in the leg soft tissues. Preservation of intraosseous pressure all along tibial diaphyseal cavity demonstrates a possibility of using its driving force to compensate for the circulatory insufficiency in the leg soft tissues and, moreover, in that part of the bone the environment of which in ischemia is involved.
