초록

위확대염전 (gastric dilatation and volvulus; GDV)는 위급하고 생명을 위협하는 질병으로 보통 대형견에서 호발한다. 하지만 17살 Shih-tzu (4 kg, 중성화 암컷)가 급성 위확대염전으로 응급내원한 경우가 있었다. 내원했을 당시 지속적인 헛구역질, 무기력, 그리고 과도하게 확장된 복부가 관찰되었다. 신체검사상 환자는 저체온증 ($36.5^{\circ}C$), 심박수 항진 (240 bpm), 느려진 모세혈관 재충만 시간 (> 2초)였고 점막은 창백한 색이었다. 폐음은 정상적이었지만 3단계의 murmur를 청진상 확인하였다. 복부타진을 통해서 복부 양쪽으로 공명하는 부위의 존재가 확인되었다. 수축기혈압은 220에서 시작해서 40 mmHg까지 4시간동안 점진적으로 감소하였다. 혈액검사상, blood urea nitrogen (BUN; 29.1 mg/dl)과creatinine (1.6 mg/dl)의 값을 토대로 미약한 질소혈증 상태였다. 혈중 젖산 농도는 (8.13 mmol/l)로 심각하게 증가해있었다. 추가적인 방사선 검사를 통해서 위확대염전을 확인하였다. 위내 압력을 줄이기 위해, 위천공과 비위삽관을 통한 기체와 액체 제거를 실시하는 동안 보조적으로 산소, 열, 수액, 그리고 약물들을 처치하였다. 또한 dobutamine의 정맥내투여에도 불구하고 수축기혈압이 일정하게 유지되지 않았고, 이에 따라 혼수상태에 빠지고 말았다. 환자의 나이와 복지를 고려하여 안락사가 결정되어 생을 마감하였다. 이번 경우는 최종적으로 위확대염전으로 진단되었으며, 이는 Shih-tzu와 같은 소형견에서 보고되는 첫 위확대염전 case라는 점에서 의의가 있다.

Gastric dilatation and volvulus (GDV) is an acute and life-threatening disease most commonly affecting large- and giant-breed dogs. However a 17-year-old Shih-tzu (4 kg, spayed female) was hospitalized for acute GDV. Repeated unproductive retching, lethargy, and excessively enlarged abdomen were observed. Physical examination indicated that the patient had suffered from hypothermia ($36.5^{\circ}C$), tachycardia (240 bpm), slowed capillary refill time (> 2 sec.), and pale mucous membrane. Grade III murmur with normal lung sound was auscultated. Abdominal palpation revealed that tympanic regions existed in both the left and right sides. Systolic blood pressure decreased gradually from 220 to 40 mmHg within 4 hours. In blood analysis, slight azotemia was observed by blood urea nitrogen (BUN; 29.1 mg/dl) and creatinine (1.6 mg/dl). Blood lactate concentration (8.13 mmol/l) was severely elevated. Additionally, dilatation and volvulus of the stomach was observed by radiograph. Supportive oxygen, heat, fluid, and drugs were administered with gastric decompressions (e.g., gastrocentesis and nasogastric tube). However the patient entered into comatose status with uncontrollable systolic blood pressure, despite the administration of dobutamine intravenously. The case was closed by euthanasia, considering welfare and age. We finally diagnosed the patient as a GDV, thus this is the first GDV case report in small-breed dog such as Shih-tzu.
