Long‐term survival of 23 dogs with pericardial effusions

Twenty-three dogs with pericardial effusions were identified from case records made between 1992 and 2000. Fourteen of the 23 were diagnosed with idiopathic pericardial effusions, and three of these were treated successfully by one pericardiocentesis. In the remaining 11 cases the pericardial effusion recurred; six cases were managed long-term by either two (three cases), three (two cases), or 11 repeated pericardiocenteses, and the remaining five were treated by pericardiectomy. The median survival time of the six dogs treated by repeated pericardiocentesis was five years and nine days.
