[Acute tamponade: complication of resuscitation (cardiac perforation by a subclavian catheter)].

The authors report a case of acute tamponnade as result of the collection under pressure of a lipid solution in the pericardium following perforation of the right atrium by a sub-clavian catheter. Diagnosis and treatment were practically siumultaneous. Aspiration of the lipid solution (450 ml) via the catheter confirmed the diagnosis and successfully treated the problem. With regard to the case, the following are discussed: - diagnostic features of acute tamponnade (acetiological, clinical, heemodynamic, electrocardiographic and radiological signs); - the physiopathological mechanism of tamponnade with changes in intra-pericardiac and ventricular pressure/volume cures; - finally, the management of tamponnade.
