Perkutane ultraschallgezielte und durchleuchtungs-kontrollierte Drainage perikardialer Flüssigkeiten

: The results of 25 ultrasonographically guided percutaneous pericardial drainage procedures and of one pericardiocentesis performed in 25 patients with pericardial fluid collections are reported. After initial puncture of the pericardial cavity under sonographic guidance, dilatation and placement of 5F to 8.3F catheters in Seldinger technique was controlled fluoroscopically in 22 procedures. Clinical indications were emergency treatment of tamponade (n = 6) or urgent treatment of large (n = 14) pericardial effusions. The remaining 6 procedures were performed to establish specific diagnoses of small effusions. Puncture sites were subxiphoid in 23 and left parasternal in 3 cases. The volume of aspirated fluid ranged from 20 to 1710 ml (median: 615 ml). Median duration of pericardial drainage was 3 days (range less than 1 day to 21 days). A specific diagnosis was obtained in 48% of patients. 4 patients had subsequent elective surgical intervention for recurrent effusion or for pericardial biopsy. Three minor complications included one vasovagal reaction and two asymptomatic pneumothoraces. Percutaneous ultrasonically guided and fluoroscopically controlled placement of a pericardial catheter is safe and effective for treatment and diagnosis of pericardial effusions.
