Prenatal diagnosis and follow-up of giant sacrococcygeal teratoma

Teratoma sacrococcígeo gigante, distocia y preeclampsia. Análisis de un caso clínico y posmortem

Sacrococcygeal teratoma is the primary extragonadal germ cell neoplasm in childhood. This tumor is usually detected in the neonatal period and may become malignant. Treatment is surgical. The incidence of this entity is low and diagnosis can be made in utero. However, prognosis is given by histopathologic correlation only. The perinatal importance of this entity lies in its size, which causes high fetal and perinatal mortality and complications such as dystocia, polyhydramnios, preterm labor, rupture of the tumor and preeclampsia.There is a risk of malignant transformation in 5% of mature teratomas. The treatment of choice is complete tumor resection and surveillance of tumoral markers is indispensable. We report a case of giant sacrococcygeal teratoma and discuss the postmortem analysis and perinatal implications.

Preoperative embolization of giant sacrococcygeal teratoma in a premature newborn

Resection of a large vascular sacrococcygeal teratoma (SCT) in a newborn has the potential to be a fatal procedure caused by hemolysis, rupture, or bleeding of the tumor. Usually, most blood supply of an SCT is derived from the middle sacral artery. As soon as these arteries have been ligated, further blood loss is minimal. There is only one previous presentation about preoperative embolization of these arteries. We present a case in which the feeding arteries of a giant SCT were embolized in an infant born at 30 weeks and 3 days of gestation. Although bleeding during the surgery was minimal, continuous need of transfusions and life-threatening hyperkalemia created severe problems during surgery, until tumor resection was completed. This is the smallest reported patient in whom SCT was preoperatively treated by embolization.

Devascularization and staged resection of giant sacrococcygeal teratoma in the premature infant

Sacrococcygeal teratoma identified in utero is associated with 50% fetal demise, which is caused by hyperdynamic cardiac failure, hemorrhage, and polyhydramnios-induced preterm labor. A premature infant (26 weeks' gestation) with prenatally diagnosed sacrococcygeal teratoma was managed successfully with initial devascularization to control the hyperdynamic state, followed by staged resection.

Clinical management of infants and newborn babies undergoing major surgery utilizing a rapid infusion device

SummaryIn this paper we describe the perioperative management of a premature infant who underwent excision of a giant sacrococcygeal teratoma, a newborn infant who had a partial hepatectomy for a haemangioendothelioma of the liver and an 18‐month‐old infant who had repair of abdominal aortic, renal and iliac arterial aneurysms. In each case a rapid infusion device was used to deliver warm, washed and ventilated blood to replace massive intraoperative blood loss. Although the blood loss in each operation was in excess of twice the total blood volume of the patient, losses were replaced effectively with the rapid infusion device without any significant hypovolaemic episodes. Successful management of newborn babies and infants undergoing surgery with large and potentially hazardous blood loss can be provided using the rapid infusion device. Paediatric anaesthesiologists should strongly consider using this technology when caring for a baby or infant during surgery where massive haemorrhage may occur.

Giant sacrococcygeal teratoma: A method of simple intraoperative control of hemorrhage

A method of emergency hemostasis and continuous intraoperative control of hemorrhage in giant sacrococcygeal teratoma, using an aortic snare, is described. A baby weighing 1,700 g with a 1,300-g sacrococcygeal teratoma was successfully operated using this technique.
