Abstract

A 3-year-old intact female Dachshund was referred due to paraplegia and cool extremities. History taking, physical examination, neurological examination, and blood profiling studies were evaluated to determine the diagnosis. Based on abdominal ultrasound and echocardiograph, features suggestive of adult heartworm were detected in aberrant places. The result of enzyme-linked immunosorbent assay (ELISA) testing with a commercial heartworm antigen kit was positive. The dog fell into a comatose state, and the client requested the dog be euthanized. On post-mortem examination, the patient was diagnosed with ectopic parasitism of heartworm in the left side of heart, aorta, aorta abdominalis, and iliac arteries, a circumstance that induced systemic thromboembolism. This case report describes the clinical, diagnostic imaging, and necropsy findings of canine ectopic parasitism of heartworm.

3세의 암컷 닥스훈트견이 뒷다리의 부전마비와 사지냉감을 주증으로 본원에 내원하였고 진단을 위해 병력청취, 신체검사, 신경계 검사 및 혈액검사를 실시하였다. 복부 및 심장 초음파 검사 결과, 심장사상충의 성충으로 의심되는 소견이 정상 기생부위 이외의 장소에서 관찰되었다. 효소면역측정법을 이용한 심장사상충 항원 키트 검사 결과 양성반응이 확인되었다. 환자는 입원 당일 혼수상태에 빠져 보호자의 요청으로 안락사 되었다. 보호자의 동의 하에서 실시된 사후 부검 결과 심장의 4방과 대동맥, 복대동맥 및 엉덩동맥에서 높은 충체 부하의 심장사상충 성충이 확인되었으며, 이로 인한 다량의 전신성 혈전색전증 또한 관찰되었다. 본 증례에서는 전신 순환계로의 개 심장사상충 이소기생의 임상적 특징과 진단 영상 및 사후 부검 결과를 소개하였다.
