[Plastic properties of the arterial bed of the cervical area in the dog].
In 12 dogs sources of blood supply for certain cervical organs have been studied in norma. Anastomoses between them are grouped according to their origin as intersystemic and intrasystemic. The main intersystemic anastomoses are situated in the superficial ventral muscles, and the intrasystemic ones--in the superficial dorsal muscles, trachea and esophagus. In 24 dogs both the common carotid and vertebral arteries have been ligated simultaneously. The main compensatory-adaptive mechanisms contribute for the collaterals to develop, dilate and acquire their winding character, for the angle of the collateral branches alteration to change. Main and additional by-pass ways of the blood stream have been revealed.
