[Partial pericardial tamponade immediately after cardiac surgery].
Partial pericardial tamponade is a critical situation frequently misdiagnosed. We describe five patients with this entity during an urgent surgical reintervention performed few hours after the initial one. We found clots compressing cardiac cavities in all, usually in the right atrium. In one of them we found also a clot compressing the left atrium. None of the patients studied had the classical clinical features of cardiac tamponade (Kussmaul's sign: pulsus paradoxus) and we found no difference in blood pressure, quantity of bleeding or pulmonary capillary pressure, considering the reinterventional moment in comparison to the values taken immediately after the initial surgery and the ones registered during the surgical reintervention. There was significative increase in the central venous pressure value, decreased urine output and drop in the cardiac index. Based on this observation, we believe it is possible to have a presumptive diagnosis of partial pericardial tamponade by bidimensional echocardiographic studies just before the surgical reintervention.
