[State of the clotting and anticoagulant systems of the blood in children with cerebrovascular insufficiency of congenital etiology].

The author investigated the hemocoagulation system in 59 children with chronic cerebrovascular insufficiency caused by sequelae of natal inadequacy of the cervical division of the vertebral column and vertebral arteries. In children examined, pronounced thromboelastographic changes were noted. These changes pointed to a tendency to hypercoagulation combined with manifestations of hypocoagulation in the third phase of the blood clotting. This is an indication of activation of the secondary anticoagulation mechanism which plays a compensatory role in preventing intravascular thrombosis.
