动脉导管未闭介入封堵术后的急性并发症的危险因素分析及治疗规范

Risk Factors and Treatment Criteria for Acute Complications after Patent Ductus Arteriosus Occlusion

摘要: 动脉导管未闭是一种常见的先天性心脏病，尤其在早产儿当中发病率较高。由于动脉导管未闭左向右分流的血流动力学特点，左心系统血流量持续增多，导致肺动脉压力增高，管壁重构，最终形成不可逆的梗阻性肺动脉高压，从而错失手术时机，因此应尽早治疗动脉导管未闭。目前介入封堵术发展迅速，已成为动脉导管未闭的首选治疗方式，但其仍存在一定并发症的发生。本文从介入封堵术治疗动脉导管未闭术后急性并发症的危险因素分析，从而讨论其防治措施及治疗规范。

Abstract: Patent ductus arteriosus is a common congenital heart disease, especially in premature infants. Due to the hemodynamic characteristics of the left-to-right shunt of patent ductus arteriosus, the blood flow of the left cardiac system continues to increase, resulting in increased pulmonary artery pressure, wall remodeling, and finally irreversible obstructive pulmonary hypertension, thus missing the opportunity for operation. Therefore, patent ductus arteriosus should be treated as soon as possible. At present, interventional occlusion is developing rapidly, and it has become the first choice for the treatment of patent ductus arteriosus, but it still has a certain complications. In this paper, the risk factors of acute complications after transcatheter closure of patent ductus arteriosus were analyzed, and the preventive measures and treatment criteria were discussed.
