Radionuclide scintiphotography in defining postoperative pulmonary vasoconstriction. Succesful results after tolazoline administration in a four-month-old infant with congenital heart disease.
99mTechnetium macroaggregated albumin has successfully been used to define severe postoperative pulmonary vasoconstriction in a four-month-old boy with D-transposition of the great vessels who had undergone a Blalock-Hanlon surgical atrial septectomy. Radionuclide imaging documented clinically suspected pulmonary vasoconstriction and led to the successful use of tolazoline (Priscoline) to reverse the vasoconstriction with improved pulmonary blood flow patterns.
