Anastomotic pulmonary hypertension after lung transplantation for primary pulmonary hypertension: Report of surgical correction

This report describes a patient who developed pulmonary hypertension 6 years after lung transplantation for primary pulmonary hypertension (PPH). Evaluation with right heart catheterization followed by pulmonary angiography, however, demonstrated that the pulmonary hypertension was secondary to an anastomotic narrowing of the pulmonary artery, rather than a recurrence of her PPH. Vascular complications of lung transplantation should be considered in patients who experience exertional dyspnea after lung transplantation. The suggestion of pulmonary hypertension on echocardiography should prompt further evaluation, including meticulous hemodynamic measurements.
