Abstract

Caval syndrome is a life threatening condition caused by heavy worm burden in right cardiac chambers including right atrium, right ventricle, and vena cava and results in mechanical interference in tricuspid valvular excursion and blood flow to lower pulmonary arteries. A mechanical worm removal is the choice of option for treating this condition in dogs. In this study, we developed a new mechanical worm removal method using modified extraction brushes for treating dogs with caval syndrome. With this newly developed method, we successfully removed heartworms in two dogs with caval syndrome. Although the number of cases applied was small, authors found this method can be a good alternative retrieval method for mechanical worm removal in dogs.

Caval syndrome은 감염된 다수의 심장사상충이 우심방, 우심실을 포함한 우심계와 대정맥으로 이동하여 삼첨판의 움직임을 물리적으로 방해하고 폐동맥으로 가는 혈류의 장애를 유발하여 생명을 위협하는 질환이다. 이 질환의 치료를 위해 외과적인 사상충의 제거가 필요하다. 본 증례는 modified extraction brushes를 이용한 새로운 방법의 심장사상충 제거 방법에 대한 보고이다. 본 연구에서 새롭게 만들어진 사상충 제거 카테터를 사용하여 caval syndrome에 감염된 두 마리의 개를 성공적으로 치료하였다. 비록 새로운 시술법의 적용이 단지 두 증례에 불과하지만, 본 시술법은 심장 사상충 치료를 위한 외과적 제거방법 중 하나로 선택할 수 있다.
