A 57-year-old woman presented with right, medial, and left congenital diaphragmatic hernia defect. The hernia defect was closed laparoscopically by a running suture and then a mesh placed as an onlay fixed with helical hernia tacks. The patient developed cardiac tamponade on the second day due to tack-induced bleeding of an epicardial artery of the inferior surface of the heart, which required emergency pericardial drainage. The outcome was good, and discharge home was allowed after 1 month.
A 62-year-old woman with gastroesophageal reflux disease and a large hiatal hernia underwent Nissen fundoplication with mesh hiatoplasty using absorbable tacks. On postoperative day 5, the patient developed acute respiratory distress syndrome with hypotension and oliguria. A thoracic CT scan showed a bilateral pleural effusion and a large pericardial effusion that caused the collapse of the right atrium and ventricle. She was taken back to the operating room for urgent surgical pericardial drainage. After that, the postoperative course was uneventful.
