RESUMO
Oneself presents the result of the prospective study from evaluate the morbility of the partial exchange-transfusion (exchange-dilution) to effect in two forms in newborn with polycythemia. The A group was newborn in the which extraction of blood volume was on peripheric vein is oneself administration crystalloid solution for another periphery vein; the B group was utilized umbilical vein to remove blood volume for another periphery vein is administration the crystalloid. To have 20 newborn in each group; to predisponent prenatal factors global were toxemic (12%); the plethora was the more frequent sing (55%) and nausea in (37%). Were not encountered difference in both groups for: gestational age, weight, birth rate, trophism, polycythemia type (asymptomatic vs symptomatic); neither to have difference in the seric electrolytes, protein and vital signs before and after procedure. Were encountered more infections process in the B group (P < 0.05). Were concluded what the exchange-dilution for polycythemia in newborn of term must be for periphery vein exclusive with security of not production metabolic and hemodynamic changes and without risk for sepsis and/or enterocolitis for manipulation of umbilical vessels.

Hepatic hemangiomas are benign vascular tumors that represent 5-15% of all liver tumors. They occur more often in females than in males (relation 2:1). They may produce cardiac failure, because of high output; less frequently hemolytic anemia, thrombocytopenia or bleeding are observed. We present a case of a newborn premature child with a gestation age of 34 weeks and weight of 1359 g who presents a palpable abdominal tumor in the right hypochondrium without additional symptoms. The diagnosis was confirmed by ultrasound with Doppler system any by means of the magnetic resonance imaging (MRI) both methods were able localize the hemangioma in the posterior segment of the right hepatic lobulus. MRI is a diagnostic tool which can provide finer anatomic details than ultrasound or axial computed tomography in hepatic hemangiomas. MRI has a sensitivity of 90% and specificity of 92%; the treatment depends of the complications which the patient presents.
