[Catheter drainage of late cardiac tamponade guided by computed tomography].
Delayed cardiac tamponade is an unusual but serious complication of cardiac surgery. Echocardiography and computed tomography (CT) are well established methods for the detection of pericardial effusions. Catheter insertion guided by CT has been used to accomplish non operative drainage of symptomatic postoperative pericardial effusion in seven cases. These patients were grouped into four types according to distribution of the fluid. General pericardial effusion around the heart is classified as type 1, effusion adjacent to the right side of the heart as type 2 and left side as type 3, effusion localized only at the apex as type 4. CT imaging is useful not only to localize and assess the size of the effusions, but also to select the way of catheter insertion. As the fluid might be trapped in compartments, for instance right-sided or left sided type, investigation of the pericardial spaces is important in planning a catheter pericardiocentesis.
