title: Coagulopathy associated with large sacrococcygeal teratomas.
abstract: Twelve neonates with sacrococcygeal teratoma (SCT) have been treated at British Columbia Children's Hospital over the past 5 years. Clinically significant coagulopathy developed in four of these neonates and two died, one before surgical intervention could be undertaken. Disseminated intravascular coagulation (DIC) was found in one patient and thrombocytopenia in another on preoperative laboratory studies. Etiology of the coagulopathy is unclear, but appears to be multifactorial. Although several clinical reviews have noted mortalities due to exsanguinating hemorrhage, no study has focused solely on this issue. The diagnosis of SCT in the neonate at high risk for development of coagulopathy is usually made prenatally. Premature labor is often precipitated by associated polyhydramnios and large tumor size. Fetal distress, prematurity, and low birth weight are common. Presence of placentamegaly, hydrops fetalis, and congestive heart failure are ominous prognostic signs. Early identification of patients at increased risk for development of hemorrhagic complications may allow optimization of their management. Cesarean section should minimize trauma to the SCT during delivery. Expeditious resection of the lesion may improve survival.
