2022年中国农业大学动物医院6822例犬X线检查病例回顾性分析

Retrospective Analysis of 6 822 Canine X-ray Examinations Cases at China Agricultural University Veterinary Teaching Hospital in 2022

为了研究X线检查在犬临床诊疗过程中的具体应用情况和主要异常诊断等,本研究对2022年1—12月中国农业大学动物医院6 822例犬X线检查病例进行回顾性分析。结果显示,1岁以下684例(10.03%),1~7岁2 101例(30.80%),7岁以上4 037例(59.18%);雄性2 828例(41.45%),雄性去势1 169例(17.14%),雌性1 464例(21.46%),雌性绝育1 361例(19.95%)。共进行X线检查8 539例次,检查类型包括平片8 510例次,造影29例次。平片检查部位由多到少依次为胸部(3 191/8 510,37.50%)、四肢骨(3 023/8 510,35.52%)、中轴骨(1 476/8 510,17.34%)和腹部(820/8 510,9.64%)。胸部主要影像学异常为肺非结构间质型(939/3 191,29.43%)和心影增大(649/3 191,20.34%);四肢骨主要影像学异常为骨关节炎(1 089/3 023,36.02%);中轴骨主要影像学异常为椎间隙狭窄(876/1 476,59.35%)和退行性病变(443/1 476,30.01%);腹部主要影像学异常为下泌尿道结石(261/820,31.83%)。造影检查包括逆行性尿路造影25例次和消化道造影4例次。逆行性尿道造影检查检出的主要异常表现/诊断为尿道狭窄(7/25,28.00%),消化道造影检查检出的主要异常表现/诊断为造影剂残留(3/4,75.00%)。结果表明,X线检查在犬类临床疾病的诊断和治疗中应用广泛,尤其在心脏疾病、骨关节疾病和泌尿道疾病方面具有重要的临床应用价值。

This study conducted a retrospective analysis of 6822 canine X-ray examinations cases at China Agricultural University Veterinary Teaching Hospital from January to December 2022 to investigate the specific applications of X-ray examinations in the clinical diagnosis and treatment of dogs and to identify the main abnormal diagnoses.The results showed that 684 cases(10.03%)were under 1 year old,2101 cases(30.80%)were between 1 and 7 years old,and 4037 cases(59.18%)were over 7 years old.There were 2828 males(41.45%),1169 castrated males(17.14%),1464 females(21.46%),and 1361 sterilized females(19.95%).A total of 8539 X-ray examinations were performed,including 8510 plain film examinations and 29 contrast radiographs.The most common examination sites for plain film examinations were the chest(3191/8510,37.50%),limbs(3023/8510,35.52%),axial skeleton(1476/8510,17.34%),and abdomen(820/8510,9.64%).The main radiographic abnormalities in the chest were lung nonstructural interstitial pattern(939/3191,29.43%)and cardiac shadow enlargement(649/3191,20.34%);in the limbs,the main abnormality was osteoarthritis(1089/3023,36.02%);in the axial skeleton,the primary abnormalities were narrowed intervertebral spaces(876/1476,59.35%)and degenerative changes(443/1476,30.01%);in the abdomen,the most common abnormality was lower urinary tract calculus(261/820,31.83%).Contrast examinations included 25 cases of retrograde urography and 4 cases of digestive tract contrast radiography. The main abnormal findings/diagnoses detected in retrograde urography were urethrostenosis (7/25, 28.00%), while the main abnormal findings/diagnoses detected in digestive tract contrast radiography were contrast media remain (3/4, 75.00%). The results indicate that X-ray examinations are widely used in the diagnosis and treatment of canine clinical diseases, particularly in the diagnosis and treatment of heart diseases, osteoarticular diseases, and urinary tract diseases.
