The technical details of the surgery were presented, the improvements on the basis of traditional methods were discussed and its clinical application was evaluated. It is concluded that pulmonary venoplasty is a safe and feasible operation. Further improvement of the surgery will help conserve more lung tissue and benefit more @entity1 because of expanded indications.
