  • Pulmonary balloon angioplasty for patients with chronic thromboembolic pulmonary hypertension accompanying with progressed pulmonary hypertension after pulmonary endarterectomy

    ObjectiveTo describe the effect of sequential pulmonary balloon angioplasty for patients with chronic thromboembolic pulmonary hypertension, who was accompanied with progressed pulmonary hypertension after pulmonary endarterectomy surgeries.MethodsFrom 2014 to December 2017, 7 patients were treated with a combination therapy of pulmonary endarterectomy and sequential pulmonary balloon angioplasty. There were 1 male and 6 females at age of 58 (43–59) years. A follow-up period of more than 1 year was accomplished. The result of right sided heart catheterization and ultrasonic cardiogram between and after the pulmonary endarterectomy or balloon angioplasty was collected.ResultsSeven patients were treated with a combination of pulmonary endarterectomy and sequential pulmonary balloon angioplasty, which included 1 patient of single pulmonary balloon angioplasty and 6 patients of multiple pulmonary balloon angioplasties. The balloon dilation times was 2 (2–6), and the number of segments during each single balloon dilatation was 3–5, compared with the first clinical results before the first balloon dilation, systolic pulmonary artery pressure [53 (47–75) mm Hg vs. 45 (40–54) mm Hg, P=0.042), mean pulmonaryartery pressure [38 (29–47) mm Hg vs. 29 (25–39) mm Hg, P=0.043], N terminal-B type natriuretic peptide [1 872 (1 598–2 898) pg/ml vs. 164 (72–334) pg/ml, P=0.018] improved significantly after the last balloon angioplasty. Heart function classification (NYHA) of all the 7 patients were recovered to Ⅰ-Ⅱclasses (P<0.05).ConclusionSequential pulmonary balloon angioplasty after pulmonary endarterectomy can further reduce the patient's right heart after load, improve the heart function for patients with progressed pulmonary hypertension after pulmonary endarterectomy surgeries.
