An 84-year-old woman suffered from a type IV diaphragmatic hernia with a tortuous intrathoracic stomach and grade II esophagitis. The stomach was reduced into the abdominal cavity and the hernia sac resected. A coated polyester mesh was attached to the crura with 5-mm titanium helical tacks. After an uneventful recovery, the patient suddenly developed cardiogenic shock on postoperative day 14. A left thoracotomy was subsequently performed. There was active bleeding of the epicardium from a number of pointed lesions, just opposite the tackers which had penetrated the pericardium. The offending tacks were removed and the defects in the epicardium sutured. The patient was discharged 18 days after thoracotomy.
An 82-year-old man presented with an 8-cm mixed hiatal hernia with grade IV esophagitis. Surgical treatment consisted of laparoscopically mesh-augmented hiatoplasty with anterior fundophrenicopexy. Because of accidental rupture of the right crus of the diaphragm, a 15 × 15 cm prolene mesh was necessary to reconstruct the hiatus. The mesh was fixed by 16 helical tacks. During the first 24 postoperative hours, deteriorating oxygen saturation with increasing dyspnea was most notable. After 48 h, the patient experienced severe retrosternal pressure with simultaneous tachyarrhythmia and consecutive circulatory failure. The patient died despite resuscitation attempts. The autopsy revealed cardiac tamponade originating from an epicardial vascular erosion caused by one of the helical tacks.
