[Pleuroperitoneal Communication Using Intraoperative Imaging with Indocyanine Green Fluorescence: Report of a Case].

A 46-year-old man was treated with ascites due to idiopathic portal hypertension. Chest X-ray showed a massive pleural effusion on the right side. Also, contrast-enhanced ultrasonography showed that contrast medium was effusing from abdominal cavity into the thoracic cavity via diaphragm. He was diagnosed with pleuroperitoneal communication. Thoracoscopic surgery was performed and thoracoscope revealed ascites with indocyanine green (ICG) drained from multiple cystic area in the central tendon of the diaphragm. After suturing with non-absorbable thread with reinforcement, the whole diaphragm was covered with a polyglycolic acid sheet and fibrin glue. Postoperatively, there was no reaccumulation of pleural effusion. ICG fluorescence intraoperative imaging was an useful method in detecting the pleural holes.
