False Thrombus in the Pulmonary Vein: Multimodality in Post–Lung Transplantation

We present the case of a 26-year-old woman who underwent bilateral lung transplantation. In the postoperative period, she developed impaired oxygenation and pulmonary opacities predominantly on the left side. Transesophageal echocardiography revealed a finding initially interpreted as thrombus in the left pulmonary vein. However, multimodality imaging established that the appearance was due to redundant donor pulmonary vein wall tissue folded at the anastomosis by the surgical technique, without significant obstruction. A multidisciplinary team chose conservative management, with good clinical and imaging outcomes at 6-month follow-up.
