title: [Life threatening embolism caused by central venous catheter fragments in psychiatric patients].
abstract: Central venous catheters are sometimes the cause of life-threatening complications. In two patients with underlying psychiatric disorders we observed an embolism as a result of catheter fragments. The first patient was a 30-year-old woman with a borderline personality disorder and several previous episodes of self-mutilation, psychogenic seizures and disturbances of consciousness. She cut her central venous line positioned in the external jugular vein when she was unattended. The intravasal fragment dislocated into the right ventricle and had to be removed by a forceps used for myocardial biopsies. The second patients was a 34-year-old mentally retarded male with a history of psychomotoric and grand mal seizures who suffered from a prolonged disturbance of consciousness with uncontrolled motor activity after four grand mal seizures. Despite physical restraint, the tip of his central venous catheter inserted through the subclavian vein broke and embolized in the right atrium. The embolus was removed by thoracotomy. To avoid these complications central venous lines should be used only when critically needed in uncooperative patients or those who display disturbance of consciousness and uncontrolled motor activity.
