Mm. Lantz et al., SERIAL REDUCTION OF VENTILATION IN LUNG WITH CONGENITAL ABSENCE OF PULMONARY-ARTERY, Clinical nuclear medicine, 20(2), 1995, pp. 126-127
A 3-year-old boy with unilateral absence of the right pulmonary artery
had a lung scan that demonstrated 46% of total ventilation on that si
de. This had fallen to 39% by 2 years later, and at 11 years after the
first study the value was 30%. Ventilation lung imaging may be useful
in demonstrating the degree of ventilatory dysfunction in a lung comp
romised by absence of the pulmonary artery. Possible causes of the pul
monary damage are discussed.
