Venous stasis and state of the microcirculatory bed in the synovial membranes]

Microcirculatory bed of the synovial membranes was investigated in experiments on dogs during venous stasis. Ligation of the femoral vein and circulatory disturbances led to the alteration of the microcirculatory bed of the synovial membranes, to the overfilling of the venules. Capillary walls became thinner and there developed swellings and protrusions. The extent of the vascular wall changes depended on the calibre of the vessels. One month after the ligation of the vein congestive phenomena in the tissue of the joint capsule proved to decline. This indicated development of collateral venous circulation.
