中新网上海5月19日电 (记者 陈静)上海在生物可降解“心脏植入器械”领域研发又取得创新突破。记者19日获悉,中国儿科心血管疾病专家、上海交通大学医学院儿科学院院长、上海新华医院院长孙锟教授为2岁幼童成功植入“可降解动脉导管未闭封堵器”,既修复了心脏缺损,又防止人体内残留金属。

动脉导管未闭是一种较常见的先天性心血管畸形,占先天性心脏病总数的12%~15%。人在胎儿时期,动脉导管是肺动脉与主动脉间的正常血流通道。婴儿出生后,开始利用肺自主呼吸,动脉导管则在24小时内自行闭合。

孙锟教授介绍,如果该通道持续不能闭合,则会导致儿童缺氧、发育迟缓、反复呼吸道感染、心脏增大和心力衰竭等症状。

据了解,以往此类手术通常采用的是传统金属封堵器,可能存在金属永久植入物的相关风险。孙锟告诉记者,可降解的封堵器植入后6个月后即可完成修复,植入人体12个月后,可降解材料会分解成二氧化碳和水,不会对人体造成损害。植入孩子体内的“可降解动脉导管未闭封堵器”是由中国企业研发制造的创新产品。

据悉,在人体内植入“可降解动脉导管未闭封堵器”此前未有报道。孙锟认为,这项创新是革命性的,具有重要的临床研究价值。据透露,未来,上海、浙江的多家知名临床医学中心也将开展相关人体临床研究。
