Advantages of oxygen inhalation therapy for postoperative pulmonary hypertension.

Total correction was performed in a case of complete transposition of the great arteries (TGA) with severe pulmonary vascular obstructive disease (PVOD). Although severe pulmonary hypertension remained after surgery, oxygenation was continued for 15 months, which included a shift to at-home oxygen inhalation therapy (HOT). Cardiac catheterization 15 months after surgery demonstrated that pulmonary hypertension was greatly improved. For patients in whom the palliative Mustard operation is considered due to severe PVOD on the basis of lung biopsy diagnosis, total correction of TGA is possible by employing HOT after surgery.
