Background And Aim Of The Study Postoperative pericardial effusion is frequent and can be complicated by cardiac tamponade. Although the different drainage techniques are well described in the setting of medical effusion, there is not a standard postoperative effusion treatment. The aim of this work was to assess the feasibility and effectiveness of the percutaneous pericardial drainage.MethodsThis a retrospective study involving 197 patients from 1990 to 2008. Drainage was performed by subxiphoid puncture (91.9%) or left parasternal puncture (8.1%) between 3 and 690 days following a cardiac procedure via median sternotomy. Effusion thickness was at least 10 mm in the subcostal echocardiography view.ResultsNo deaths directly related to the procedure were observed. Complete and enduring drainage was achieved in 158 patients (80.2%). The procedure failed for 22 patients (11.2%) because no fluid was drained in 14 cases (7.1%) and a right ventricular puncture in 8 cases (4.1%). Recurrence of the effusion, which occurred for 17 patients (8.6%), was more frequent if an effusion of more than 5 mm persisted after the first drainage (P = 0.024) and if the drainage was performed outside the operating room because of emergency (P = 0.046). Risk factors for mortality were recurrence of the effusion (P = 0.04) and drainage performed outside the operating room (P = 0.007).ConclusionsPercutaneous pericardial drainage is effective to treat postoperative pericardial effusion. When the effusion is thicker than 10 mm and accessible, it can be the initial strategy and surgical drainage can serve as an alternate strategy in case of failure and complications of this procedure.©2011, Wiley Periodicals, Inc.
