摘要: 目的:对房间隔缺损 (atrial septal defect, ASD) 合并显著肺动脉高压 (pulmonary arterial hypertension, PAH) 患者介入封堵术后进行中长期随访, 评估临时封堵试验和选择性肺动脉造影对分流闭合前确定PAH是否可逆的长期预测的有效性及安全性。方法:纳入2008-2018年8例ASD合并显著PAH患者。采用联合评估方法确定患者是否能手术治疗。其中3例患者因介入术后肺动脉压力仍较高而接受PAH特异性药物治疗。整理分析患者介入封堵前、术后1d、术后1个月及≥6个月随访终点时的超声心动图资料。结果:所有患者均直接进行介入封堵治疗。随访6~48 (27.63±15.22) 个月期间, 超声估测的肺动脉收缩压 (estimated systolic pulmonary artery pressure, sPAP) 与术前相比显著降低[ (52.00±17.73) mmHg∶ (27.63±7.42) mmHg, 1mmHg=0.133kPa, P=0.002]。其中2例患者术后肺动脉压力过高, 在PAH特异性药物终止后仍能逐渐下降至接近正常。结论:对符合联合评估的与ASD相关的显著PAH患者采取先手术后PAH特异性药物的治疗策略是安全和有效的。Abstract: Objective:To evaluate the effectiveness and safety of temporary occlusion test and selective pulmonary angiography in long-term prediction of reversibility of atrial septal defect (ASD) with pulmonary hypertension (PAH) before shunt closure.Method:Eight ASD patients with significant PAH from 2008 to 2018 were enrolled.The joint assessment was used to determine whether patients could be treated surgically.Among 8 patients, 3 cases received PAH-specific drug therapy because of the high pulmonary pressure after interventional therapy.The echocardiographic data of patients before interventional occlusion, 1 day after operation, 1 month after operation, and the end point of follow-up of more than 6 months were analyzed.Result:All patients were treated with interventional occlusion directly.During a follow-up with 6 to 48 (27.63±15.22) months, the estimated systolic pulmonary artery pressure (sPAP) estimated by ultrasound was significantly lower than that before surgery[ (52.00±17.73) mmHg vs. (27.63± 7.42) mmHg, 1 mmHg=0.133 kPa, P=0.002].In 2 cases, the pulmonary artery pressure was too high after operation, and it gradually decreased to near normal after the termination of PAH-specific drugs.Conclusion:It is safe and effective to receive PAH-specific drug therapy after operation for patients with significant ASD-related PAH who accept the joint assessment.
