Am J Cardiol:支架置入治疗儿童主动脉缩窄安全有效

  《美国心脏病学杂志》(Am J Cardiol)2012年2月20日在线发表了希腊的一项前瞻性研究,证实对于选择性儿童主动脉缩窄(CoA)患者,支架置入术是一种安全、有效的传统外科替代治疗手段。   虽然应用支架置入术作为治疗选择的CoA患者日趋年轻化,然而对于儿童CoA患者,支架置入治疗的长期随访信息尚不完善。该研究共纳入74例接受支架置入术治疗的儿童CoA患者[平均年

  《美国心脏病学杂志》(Am J Cardiol)2012年2月20日在线发表了希腊的一项前瞻性研究,证实对于选择性儿童主动脉缩窄(CoA)患者,支架置入术是一种安全、有效的传统外科替代治疗手段。

  虽然应用支架置入术作为治疗选择的CoA患者日趋年轻化,然而对于儿童CoA患者,支架置入治疗的长期随访信息尚不完善。该研究共纳入74例接受支架置入术治疗的儿童CoA患者[平均年龄为(8±3)岁]。其中,42例为单纯先天性CoA,32例为复发性CoA。共有87枚支架置入74例受试者的体内(包括71例裸金属支架和3例覆膜支架)。

  随访结果表明,32例患者接受了先前置入支架的再扩张。支架置入后,患者收缩期压力梯度的峰值即刻下降,由(68±16)mmHg降至(8±5)mmHg(P <0.05),缩窄主动脉的直径由(5±3)毫米增加至(16±3)毫米(P <0.05)。研究中最严重的手术并发症为1例患者发生的动脉瘤形成,该患者成功接受了覆膜支架置入术治疗。

  6年随访期间未发现早期或晚期的死亡病例和晚期的动脉瘤形成。3例患者发生了晚期支架断裂。随访结束后,多排螺旋CT或磁共振成像检测未发现再缩窄,67例患者(85%)在未使用药物的情况下血压正常。
