Implantation of a total abdominal mesh plastic ending up in multiple, lethal right heart injuries

Abstract

We present the case of a 62-year old patient who had an elective surgery to implant a total abdominal plastic mesh due to massive herniation after prior lower body gun shots and deep wound infections. Twenty-four hours after the operation, the patient's condition deteriorated, ST-deviation occurred and the Troponin I test was positive. On admission, the patient needed moderate catecholamine therapy and echocardiography showed a pericardial effusion (>3 cm). Puncture of the effusion was impossible due to the plastic mesh and the patient was transferred to the operating room. A subxiphoidal pericardial incision was performed and 800 ml of fresh blood was drained. Despite this, the patient's condition worsened. A full sternotomy was performed, and intrathoracal cardiopulmonary resuscitation started. During examination of the pericardium and the heart, multiple plastic parts from the mesh fixation system were observed transdiaphragmally and were found to have penetrated the diaphragmal part of the right ventricle. In spite of maximum drug, respiratory and surgical therapy, a sufficient heart ejection fraction could not be achieved. Upon interdisciplinary consent, therapy was stopped after 60 min.
