| With the progress and development of society,more and more pets appear in people’s lives as spiritual companions and partners.As the number of elderly dogs increases year by year,the incidence of canine disc herniation disease also shows a trend of increasing year by year,and the disease is gradually valued by pet owners and pet doctors.Clinically,the diagnosis of canine disc herniation disease is mainly based on clinical examination and imaging.The use of computed tomography(CT)and magnetic resonance imaging(MRI)in pet clinics has greatly enriched the diagnosis of the disease.In this paper,the epidemiological investigation of canine disc herniation disease was carried out,and 251 cases of dogs were analyzed,and the pathogenesis and treatment methods of canine disc herniation disease in pets were summarized,and the accuracy of CT technology and MRI technology in the diagnosis of this disease was compared.Methods: In this study,251 dogs with intervertebral disc herniation were treated in several large referral pet hospitals in southwest and northeast China,and the relevant factors of the incidence of canine intervertebral disc herniation disease were investigated and analyzed,involving the breed,age,sex,site of onset and pathogenesis type of pets.The onset sites include cervical,thoracic,lumbar and sacral vertebrae,which are divided into C1-C5,C6-T2,T3-L3,and L4-S3 according to intervertebral disc spinal cord neurology;The types of incidence include Hansen type I intervertebral disc herniation,Hansen type II intervertebral disc herniation,intervertebral disc herniation subclassification,etc.Treatment methods include conservative treatment,surgical treatment,recording both CT and MRI examination,and the types of intervertebral disc herniation in cases that underwent surgical treatment within one week,including disc bulge,intervertebral disc herniation,disc degeneration and prolapse,and the location of intervertebral disc herniation,including central type,paracentral type,intervertebral foramen type,and lateral foraminal type.Taking intraoperative exploration diagnosis as the gold standard,one-way ANOVA was performed by SPSS 26.0 software system to explore the accuracy of CT examination and MRI examination for the diagnosis of this disease.By analyzing the diagnosis,treatment and prognosis of 10 typical cases,the feasibility of treating canine disc herniation disease was discussed,which provided reference significance for the diagnosis and treatment of canine disc herniation disease in the clinical diagnosis and treatment of pets.Results: From 2020 to 2023,a total of 251 well-documented cases of dogs with disc herniation disease were collected,only after CT scanning,99 confirmed cases,only MRI scanning,76 confirmed cases,and 76 confirmed cases after simultaneous CT and MRI scanning.There were 169 cases(169/251,67.33%)in dogs with achondroplative dysplasia,accounting for the highest incidence of canine intervertebral disc disease.Among the chondroplasia breeds,77 cases of miniature poodles(77/251,30.68%)were the dog breeds with the highest incidence among the 26 breeds of dogs counted,followed by 57 cases of French bulldogs(57/251,22.71%).Disc herniation in dogs with achondroplasia was more likely to occur at the age of 5,38 cases(38/251,15.14%),and normal dogs were more likely to occur at the age of 8,13 cases(13/251,5.18%).The number of dogs with intervertebral disc herniation disease was about twice that of 167 male dogs(167/251,66.53%)compared with 84 female dogs(84/251,33.47%).Canine intervertebral disc herniation disease was mainly single-site disease,218 cases(218/251,86.85%),of which 88 cases(88/218,40.37%)in the T3-L3 segment were the most common sites of canine intervertebral disc disease,followed by 75 cases(75/218,34.40%)in C1-C5 segment and 10 cases(10/218,4.59%)in C6-T2 segment,with the lowest incidence.MRI had a high overall detection accuracy for the diagnosis of bulging disc bulge,herniated disc and disc degeneration in dogs,and was statistically significant compared with CT examination(P<0.05).The accuracy of MRI in intervertebral disc herniation was higher than that of CT examination,which was statistically significant(P<0.05).The accuracy of CT examination in the paracentral type of intervertebral disc herniation was higher than that of MRI,but it was not statistically significant(P>0.05).Conclusion: The dog breeds suffering from herniated disc disease are mainly chondroplasia breeds,among which the miniature poodle has the highest incidence,followed by the French Bulldog;The age of onset of dogs with achondroplasia is mainly concentrated in 5 years old,tending to be young dogs,and the age of onset of normal dogs is mainly concentrated in 8 years old,tending to be elderly dogs.Canine disc herniation disease is mainly single-site disease,according to spinal nerve segmentation,T3-L3 spinal cord segmentation is the common site of canine intervertebral disc disease.CT and MRI examination have high diagnostic value for the diagnosis of canine disc herniation,MRI examination has a higher accuracy rate for the detection of canine disc herniation type,and CT examination has advantages in the rapid screening of canine disc herniated disease.The combination of the two can improve the accuracy of diagnosis of canine disc herniation in veterinary clinics. |
