Gambaran CT Scan Toraks pada Kasus Efusi Pleura Transudat dan Eksudat di RSUP Haji Adam Malik Medan pada Bulan Januari – September 2024

Abstract

Background. Pleural effusion is the most common pleural disease. The nature of pleural effusion is based on the diagnosis of thoracentesis, but Computed Tomography (CT) scan of the chest can be used to evaluate the nature of pleural effusion to avoid complications of thoracentesis. Objective. To determine the CT scan of the chest findings in patients with transudate and exudate pleural effusion at Haji Adam Malik General Hospital, Medan. Method. This study is a descriptive analytical study with a retrospective cross-sectional study design conducted on patients with pleural effusion at Haji Adam Malik General Hospital, Medan. Results. Of the 80 samples, 57 (71.3%) exudate patients and 23 (28.7%) transudate patients were found with 37 females (46.3%) and 43 males (53.8%) and an average age of 48.44 ± 18.532 (2-84) years. There is a correlation between the etiology of pleural effusion and pleural nodules with the type of exudate and transudate pleural effusion (p = 0.000 and p = 0.023). There is no correlation between age, gender and other thoracic CT scan images with the type of pleural effusion (p> 0.05). The Mann-Whitney test showed that the attenuation value was good at differentiating the type of pleural effusion (p = 0.000). The cutoff attenuation of thoracic CT scan was 17.5 HU (AUC 0.887; Sensitivity 84.2%; Specificity 82.6%). Conclusion. There is a significant difference between exudate and transudate pleural effusion in terms of etiology, pleural nodules and thoracic CT scan attenuation value.
