BACKGROUND: Pleural effusions remain a common postoperative complication following lung transplantation, occurring in 10% to 26% of cases. We aimed to explore potential clinical or radiographic features associated with clinically significant post-lung transplant pleural effusions requiring repeat interventions for their management.
METHODS: Lung transplantation recipients who underwent thoracentesis at our institution between June 2012 and October 2022 were reviewed. In total, 77 patients were included. Data were collected via the electronic health record and adjudicated through direct chart review. Patients were stratified by the need for a single thoracentesis (control group) or additional interventions, including serial thoracentesis, pigtail placement, and surgery (composite group). The computed tomography (CT) of the chest before the first thoracentesis was reviewed by a thoracic radiologist who was blinded to patient outcome.
RESULTS: Single thoracentesis was used to manage 25 (32.5%) patients, 4 (5.2%) required multiple thoracenteses, 42 (54.5%) required a pigtail catheter, and 6 (7.8%) required decortication for definitive management. In the composite group compared with the control group, who were managed by a single thoracentesis, there was an increased incidence of loculations (36.8% vs. 8%, P=0.01), rounded atelectasis (22.8% vs. 4%, P=0.05), and larger effusion size (P=0.01). The composite group had higher pleural fluid eosinophils (0.33% vs. 0% in control, P = <0.01) and monocytes (14.8% vs. 7.3%, P=0.04) levels.
CONCLUSION: Baseline imaging, such as larger effusion size, loculations and rounded atelectasis, and pleural fluid cell profile with increased eosinophils and monocytes, can potentially identify clinically significant and refractory pleural effusions.
