Blood coagulation studies in children with surface hemangiomas.
Thirty patients with surface hemangiomas were investigated for any latent coagulopathy. Whole blood clotting time, kaolin cephalin clotting time, prothrombin time, thrombin time and platelet counts did not differ significantly from the control group values. The values of plasma fibrinogen, euglobulin lysis time and serum levels of fibrinogen degradation products remained within the normal ranges but their mean values were significantly different from those of healthy children. The findings may be attributed to a chronic incipient type of "consumption coagulopathy" occurring locally in the hemangiomas.
