Pulmonary endarterectomy (PEA) is the standard treatment for chronic thromboembolic pulmonary hypertension. However, it poses risks of perioperative vascular complications, which can lead to serious clinical outcomes. This study introduces a novel noninvasive and radiation-free clinical imaging tool, electrical impedance tomography (EIT), for real-time bedside assessment of lung perfusion after PEA. It identifies ventilation-perfusion mismatches arising from postoperative complications, particularly valuable for patients with hemodynamic instability, thus eliminating risks tied to CT room transfers. The article reports a case where EIT was used to identify an in-situ thrombosis post-PEA, marking the first such application. The emphasis is on early detection using EIT, which offers a promising approach for therapeutic interventions and improved postoperative evaluations.
肺动脉内膜剥脱术（PEA）是慢性血栓栓塞性肺动脉高压的标准治疗方法。然而，它存在围手术期血管并发症的风险，可能导致严重的临床后果。本研究引入了一种新型的无创且无辐射的临床成像工具——电阻抗断层成像（EIT），用于在PEA术后实时床边评估肺灌注。它可识别术后并发症引起的通气-灌注不匹配，这对血流动力学不稳定的患者尤为有价值，从而消除了与转至CT室相关的风险。本文报道了一例使用EIT识别PEA术后原位血栓形成的病例，这是首次此类应用。重点在于使用EIT进行早期检测，这为治疗干预和改善术后评估提供了一种有前景的方法。
