[Cardiac tamponade and central venous catheterization].

A 32-year-old female patient was operated on for a residual colonic stricture occurring after hemicolectomy. A right internal jugular central venous catheter was inserted during the anaesthetic for postoperative parenteral feeding. The anaesthetic combined both general and epidural anaesthesia, the latter being continued for postoperative analgesia (10 ml.h-1 of 0.125% bupivacaine). Two days later, the patient complained of sudden chest pain, with restlessness, tachycardia, cyanosis, resulting in ventricular tachycardia and cardiac arrest. When admitted to the surgical intensive care unit, the patient was in deep coma and had nonsustained ventricular tachycardia, a left haemopneumothorax and a pneumopericardium. The patient died before a definitive diagnosis was made. Postmortem examination revealed an ulcerated anterior pillar of the tricuspid valve, as well as a perforation of the right ventricle and a communication between the pericardium and the left pleural cavity. The diagnosis and treatment of this rare life-threatening complication may be very difficult. It prevention consists in using short catheters for internal jugular venous access, and checking the tip's position radiologically by opacifying the catheter.
