Abstract

Hemangiomas are common newborn vascular tumors occurring in up to 2.5 percent of newborns. Most are benign and 70 to 80 percent regress by age seven. Some hemangiomas are life threatening--1 in 300 is associated with coagulopathy. Kasabach-Merritt syndrome (KMS), associated with hemangioma, disseminated intravascular coagulopathy, microangiopathic anemia, and thrombocytopenia, can have profound sequelae. Morbidity and mortality are influenced by the anatomic location and size of the hemangioma. Untreated KMS has a 10-37 percent mortality rate. Bleeding secondary to the consumptive coagulopathy is the primary cause of death in these patients. As of 1997, there have been approximately 205 cases of KMS reported in the literature. This case study discusses the pathophysiology, clinical manifestations, diagnostics, treatment modalities, differential diagnosis, and psychosocial considerations of KMS.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
