THE USE OF TOTAL CIRCULATORY ARREST IN THE SURGERY OF GIANT HEMANGIOMA AND KLIPPEL-TRENAUNAY-SYNDROME IN NEONATES

Two neonates required deep hypothermia and circulatory arrest to provi de a central control of blood loss for the resection of giant cavernou s hemangiomas. Both infants were placed on cardiopulmonary bypass, coo led to 16-degrees, and exsanguinated before resection of these periphe ral lesions. The surgery was done as a lifesaving measure in both inst ances because both infants were suffering from high-output cardiac fai lure. In both cases, the small total blood volumes were critical in ex cision of these hypervascular tumors. Use of the techniques described allowed for the surgery to be performed in a bloodless field over a sh ort period (one hour), thus preventing massive blood loss. Both patien ts are living with no neurologic or developmental deficits more than f ive years after the operations.
