title: [Intravital study of the vasa vasorum by the transmural vasoscopy method].
abstract: The paper presents a method of transmural vasoscopy for intravital observation of vasa vasorum in the wall of main blood vessels in acute experiments in anesthetized dogs. The optical part of the cytoscope introduced into the vessels under study (the portal vein, vena cava or aorta) via the nearest largest branch was used as a source of light. For this purpose, a longitudinal cut 0,5 cm long was made in the vessel between two clamps put at a distance of 2-2,5 cm from one another. The part of the cytoscope was inserted through the cut, the vessel was ligated proximally to the cut and the proximal clamp was removed. Then the optical part of the cytoscope was introduced in the lumen of the vessel under study at a distance of 4-5 cm. The microscope MBS-1 mounted on a specially constructed bracket was used for visual observation and measuring morphological parameters of vasa vasorum. A special tubus was put on one of the oculars with a camera fixed to it. On filming in falling and passing light observations and focussing were performed through the free ocular.
