Abstract

Balloon pulmonary angioplasty (BPA) has emerged as a guideline-recommended therapy for surgically inoperable chronic thromboembolic pulmonary hypertension (CTEPH). Lung injury occurs in approximately 6% of BPA sessions and is the leading cause of procedure-related mortality. While lung injury post-BPA has recently been associated with vascular injury and hemorrhage, pathologic evidence is lacking regarding whether injury is uniformly hemorrhagic or whether a permeability-mediated pattern, such as seen in reperfusion edema, predominates in some cases. We present a case of severe BPA-associated lung injury resulting in mortality, report the first histopathologic characterization of the parenchymal injury pattern in this setting, and describe how these findings informed successful rescue veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in a second case.

球囊肺血管成形术治疗CTEPH后肺损伤:组织病理学结果和处理意义。
球囊肺血管成形术(BPA)已成为一种指南推荐的治疗手术不能操作的慢性血栓栓塞性肺动脉高压(CTEPH)的方法。大约6%的BPA治疗过程中会发生肺损伤,并且是手术相关死亡的主要原因。虽然bpa后的肺损伤最近与血管损伤和出血有关,但病理证据缺乏关于损伤是均匀出血性的,还是通透性介导的模式,如再灌注水肿,在某些情况下占主导地位。我们报告了一例严重双酚a相关肺损伤导致死亡的病例,报告了这种情况下实质损伤模式的第一个组织病理学特征,并描述了这些发现如何为第二例成功的静脉-动脉体外膜氧合(VA-ECMO)抢救提供了信息。
