Background:
Chronic thromboembolic pulmonary hypertension is a late sequela following acute pulmonary embolism. Incomplete resolution of thrombotic material results in persistent obstruction of the pulmonary arterial bed, which can be treated by pulmonary thrombendarterectomy.
Method And Results:
This desobliteration of the pulmonary arteries is performed under conditions of deep hypothermia and circulatory arrest. Currently, perioperative mortality ranges between 10 and 15% and is mainly limited by persistent diffuse pulmonary artery disease independent of central obstruction. Postoperatively, pulmonary vascular resistance is normalized. Exercise tolerance of the patients is likewise improved.
Conclusion:
Thus, pulmonary thrombendarterectomy is an effective treatment for chronic thromboembolic pulmonary hypertension with results superior to those of lung transplantation.
