CT directed diagnostic and therapeutic pericardiocentesis: 8-year experience at a single institution.

UNLABELLED

A retrospective review of the 8-year experience at a single institution performing more than 300 CT directed pericardiocenteses was performed. The technique, results, and complications were determined. Comparative data from the literature relating to cardiology and thoracic surgery are reviewed. A CPT code data base search was performed to identify all imaging directed pericardiocenteses at a 550 bed regional medical center between 1993 and 2001. Medical records, imaging studies, and reports as well as pertinent laboratory, chemistry and hematology values were reviewed. Demographics, results, fluid analyses, techniques, systems used and complications were recorded.

RESULTS

Three hundred and nineteen pericardiocenteses using CT localization were attempted on 261 patients. One hundred and forty-two men were included and mean age was 61 years (range 6 months to 89 years). Mean volume aspirated was 418 cc (range 0-1,875 cc). The major complication rate was 0.3%; the minor complication rate was 6.9%. Technical success was achieved in 98.4% procedures. Emergent pericardiocentesis was performed on anticoagulated patients without significant bleeding. Seventy-nine percent of patients with echocardiographic evidence of tamponade had symptomatic improvement. Patients with marked shortness of breath without other evidence of tamponade benefited symptomatically in 78%. Pericardiocenteses with CT localization is relatively safe and many patients achieve symptomatic relief.
