A 3-year-old, intact male Pungsan dog was presented for a 2-week history of a non-weight-bearing lameness of left hindlimb with anorexia. The dog had no history of trauma, and never been routinely vaccinated or treated with heartworm preventatives. The complete blood count showed severe leukocytosis and neutrophilia with left shift. Serum biochemistry showed hypoalbuminemia, azotemia, and increased hepatobilliary enzyme activity. A canine heartworm antigen test was positive. Thoracic radiographs were consistent with heartworm disease as evidences by main pulmonary artery enlargement, right-sided cardiomegaly, and interstitial lung pattern. Echocardiography revealed pulmonary valvular regurgitation and pulmonary hypertension. Selective femoral arterial angiogram was performed, and bilateral femoral arterial occlusion was identified. The dog died after angiogram, and necropsy was performed. At necropsy, adult heartworm and a large blood clot were found within the lumen of left and right femoral artery. This case report describes an unusual migration of heartworm to femoral artery that caused hindlimb lameness.

문제 정의
Several reports suggested aberrant migration of heartworm such as brain, spinal cord, epidural space, anterior chamber, vitreous, peritoneal cavity, subcutis, and femoral artery (6-8,13,15). This report describes a case presented for acute hindlimb lameness resulting from bilateral femoral arterial occlusion by Dirofilaria immitis.
제안 방법
A canine heartworm antigen test was positive. Radiographic examination was performed of thorax, abdomen, and both pelvic limbs. Abdominal radiographs showed decreased serosal detail due to emaciation, and radiographs of pelvic limb showed decreased muscle mass of left thigh muscle (Fig 2).
성능/효과
, withdrawl, patella, perineal, cutanenous trunci) were normal. The complete blood count (CBC) abnormalities included severe leukocytosis, neutrophilia with left shift, mild monocytosis, decreased hematocrit, and hemoglobin. Serum biochemistry abnormalities included decreased albumin, and marked increased alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma(γ)-glutamyl transferase (GGT), blood urea nitrogen (BUN), and creatinine (Table 1).
