Pulmonary hypertension (PH) may be the result of many different pathological processes. PH is a rare but recognized vascular complication following major lung resection. We describe the diagnosis and management of moderate PH resulting more than 50 years in a patient who underwent a total unilateral pneumonectomy in infancy. Unfortunately, patients who undergo pneumonectomy will likely go on to develop PH and their functional status will be greatly impacted. In the case presented, we report on a patient whose PH and symptoms improved following off-label WHO group 1 treatment.

肺动脉高血压：婴儿期肺切除术后五十年。

肺动脉高压（PH）可能是许多不同病理过程的结果。PH 是主要肺切除术后罕见但公认的血管并发症。我们描述了一名在婴儿期接受全单侧肺切除术的患者 50 多年来中度肺动脉高压的诊断和治疗。不幸的是，接受全肺切除术的患者可能会继续发展肺动脉高压，其功能状态将受到极大影响。在所介绍的病例中，我们报告了一位患者在接受 WHO 第 1 组标签外治疗后，其 PH 值和症状有所改善。
