摘要
Pulmonary thromboendarterectomy （PEA） is the recommended treatment for chronic thromboembolic pulmonary hypertension （CTEPH）.1 Pulmonary artery injury is a major risk factor during PEA performed at less experienced surgical centers and is associated with adverse short-term consequences.In-hospital mortality may be as high as 15% in some PEA case series,with pulmonary artery injury and persistent pulmonary hypertension as the principal etiologies.2 Many techniques have been used to prevent pulmonary artery injury during PEA,but once the injury occurs,the prognosis is poor and may even result in death.Out of 202 PEA procedures performed at our surgical center,we successfully managed two cases of severe pulmonary artery injury and report our experience in the present case series.Keywords：chronic thromboembolic pulmonary hypertension; pulmonary thromboendarterectomy; pulmonary artery injury
