Chronic thromboembolic pulmonary hypertension (CTEPH) is a subtype of pulmonary hypertension characterized by a mean pulmonary artery pressure ≥25 mm Hg due to obstructive fibrotic thromboembolic material in the pulmonary arteries. Malignancy is a significant risk for developing CTEPH. The option for inoperable CTEPH is largely medical with variable outcomes. Balloon pulmonary angioplasty (BPA) is a promising option for inoperable patients given distal-type CTEPH, co-morbidities, or residual pulmonary hypertension after surgery. We present a case of a patient with prostate cancer and CTEPH successfully treated with balloon pulmonary angioplasty.
慢性血栓栓塞性肺动脉高压（CTEPH）是肺动脉高压的一种亚型，其特征是由于肺动脉中存在阻塞性纤维性血栓栓塞物质，导致平均肺动脉压≥25 mmHg。恶性肿瘤是发生CTEPH的一个重要风险因素。对于无法手术的CTEPH患者，主要治疗手段是药物治疗，但其效果各异。对于因远端型CTEPH、合并症或术后残留肺动脉高压而无法手术的患者，球囊肺动脉血管成形术（BPA）是一种有前景的治疗选择。我们报告一例前列腺癌合并CTEPH患者成功接受球囊肺动脉血管成形术治疗的病例。
