Percutaneous laser ablation of sacrococcygeal teratoma in a hydropic fetus with severe heart failure–too late for a surgical procedure?. However, Medwave reserves the right to remove it later if the editors consider your comment to be: Fetal echocardiography to rule out congenital heart disease and to assess fetal cardiac function.
Contraindications Contraindications to fetal intervention for SCT include the following [ 13 ]: Rapid growth of large vascular tumors can rupture and hemorrhage during delivery, and this is usually fatal. The present article provides a literature review on the follow-up, complications and intrauterine management of these fetal tumors, with reference to diagnostic imaging, routes of delivery and the intrauterine treatment proposed by distinct authors.

Prenatal diagnosis and prognosis]”. It originates from multipotential embryonic stem cells and most tumors arise from the anterior surface of the sacrum or coccyx. Sonographic prognostic factors in prenatal diagnosis of SCT. Placentomegaly and hydrops are harbingers of fetal demise in SCT. A proper aligned sacroccoccigeo lumbosacral spine is observed in the tomography.
Congenital malformations and deformations of nervous system Q00—Q07— Cystic type IV sacrococcygeal teratoma. Underlying skin without histological alterations observed. The surgery should include reattachment of the small muscles and ligaments formerly attached to the coccyx, in effect reconstructing the posterior perineum. A control ultrasound was performed at 32 weeks of pregnancy in which tumor volume increased with a probable diagnosis of cystic hygroma.
Type II – Predominantly external but has a significant intrapelvic component. High-output cardiac failure in fetuses with large sacrococcygeal teratoma: Prognostic saccrococcigeo of tumor-head volume ratio in fetal sacrococcygeal terato,a.
All fetuses who did not develop hydrops survived.
The couple opted for termination of pregnancy and the histopathological analysis confirmed an immature teratoma with an important extension into the pelvic cavity, causing anterior displacement of the perineum and pelvic organs. Pathologic examination confirmed the diagnosis of sacrococcygeal teratoma. Background Sacrococcygeal teratoma SCT is the most common congenital germ cell tumorwith an incidence of 1 in 35, tertaoma births [ 1 ] and a female predominance 3: Risk factors for perioperative mortality and transfusion in sacrococcygeal teratoma resections.
Perinatal outcome of sacrococcygeal teratoma.
Fetal Surgery for Sacrococcygeal Teratoma
Conversely, oligohydramnios can also occur if an intrapelvic portion of the tumor causes significant urinary obstruction. Whereas type I tumors, being primarily external to the fetus, are easily diagnosed prenatally and are amenable to fetal resection, type IV tumors can be difficult to diagnose and are not amenable to fetal resection.
The key to optimizing survival in these fetuses is intervention before the development of high-output cardiac failure, hydrops, and maternal mirror syndrome.
Posterior view of the newborn after surgery. Thermocoagulation of fetal sacrococcygeal teratoma. Studies on fetuses with SCT show that combined cardiac output increases dramatically before the development of hydrops. Your comment will be published as soon as it is posted. However, in case of rapid tumor growth or arteriovenous shunt, there is a high probability of developing heart failure and terato,a death 1.

Complications of the mass effect of sacrociccigeo large SCT may include hip dysplasiabowel obstructionurinary obstructionhydronephrosis and hydrops fetalis. Lesions diagnosed at two months of age, are more likely to contain malignant tissue.
Diagnóstico pré-natal de teratoma sacrococcígeo
Fetal SCTs that are sacrovoccigeo internal may be undetected if they are small; detection or at least suspicion is possible when the fetal bladder is seen in an abnormal position, due to the SCT pushing other organs out of place. InWilson et al proposed the following criteria for surgical resection of sacrococcygeal teratoma [ 13 ]:. Key words Sacrococcygeal teratoma.
Synonyms or Alternate Spellings: Some possible causal factors for recurrence include incomplete resection with microscopic residues, non all coccyx resection and tumor spread. The mass was detected on gestation week 24 in the sacrococcygeal area and was initially interpreted as a myelomeningocele. It was scheduled for cesarean section at 38 weeks of gestation and a single live male product is obtained, with ApgarSilverman Anderson 0, Capurro test: Testicles and penis with no alterations.
Other ultrasound signs include the presence of alterations caused by compression of adjacent structures, as the bladder sacrococcigei and dysplastic kidneys evident on this image.
