Abstract:
A 13-year-old female patient with a pulmonary arteriovenous fistula (PAVF) of 24 percent shunt fraction (SF) underwent resection of segments 8 and 9 of the left lower lobe. Three months after the operation, the shunt became insignificant and PaO2 was normalized. In terms of the maximum work rate, maximum VO2 and the VO2-blood lactate relationship, this patient showed a remarkable postoperative improvement in the exercise capacity.
