Objective: The aim of this study is to evaluate the radiographic findings of structural disorders of the columna vertebralis, disc herniations, fractures and luxations due to trauma, or degenerative and tumoral formations encountered in street animals. Materials and Methods: 200 stray animals (cats and dogs) of different breeds, ages, genders and weights in the Balıkesir region were studied in this study. Routine clinical, neurological and radiological examinations of cats and dogs brought to Balıkesir Metropolitan Municipality, Street Animals Temporary Care Home and Rehabilitation Center and Balıkesir University, Faculty of Veterinary Medicine Animal Hospital Clinics between 2019-2021 for various reasons were carried out. Results: In the radiological examination, columna vertebralis pathologies were detected in 60 of 200 animals (30%). 21 (35%) of these animals were cats and 39 (65%) were dogs, 30 (50%) were female and 30 (50%) were male. In radiological evaluation, vertebral fracture (n=12, 57%), spondylosis deformance (n=3, 14%) and foreign body (n=2, 10%) were detected in cats; spondylosis deformans (n=25, 64%), vertebral fracture (n=9, 24%), disseminated idiopathic spinal hyperostosis (n=5, 13%), discospondylitis (n=4, 10%), vertebral subluxation (n =2, 5%) and neoplasia (n=1, 3%) were detected in dogs. Conclusion: Many vertebral diseases in cats and dogs are diagnosed through physical, neurological and radiological examinations. Although radiological examination is two-dimensional and provides low diagnostic detail compared to advanced imaging techniques, it is still an auxiliary diagnostic method that should be preferred first because it does not require anesthesia and is low cost.

Kedi ve Köpeklerdeki Vertebra Lezyonlarının Radyografik Olarak Değerlendirilmesi

Öz

Amaç: Bu çalışmanın amacı sokak hayvanlarında karşılaşılan columna vertebralis’in yapısal bozuklukları, disk fıtıkları, travmaya bağlı kırık ve luksasyon ya da dejeneratif ve tümöral oluşumlarının radyografik bulgularının değerlendirilmesidir. Gereç ve Yöntem: Balıkesir bölgesinde bulunan farklı ırk, yaş, cinsiyet ve kilodaki 200 sokak hayvanı (kedi-köpek) bu çalışmada ele alındı. Çeşitli nedenler ile 2019-2021 yılları arasında Balıkesir Büyükşehir Belediyesi, Sokak Hayvanları Geçici Bakımevi ve Rehabilitasyon Merkezi ve Balıkesir Üniversitesi, Veteriner Fakültesi, Hayvan Hastanesi Klinikleri’ne getirilen kedi ve köpeklerin rutin klinik, nörolojik ve radyolojik muayeneleri gerçekleştirildi. Bulgular: Radyolojik muayenede 200 hayvanın 60’ında (%30) columna vertebralis patolojileri belirlendi. Bu hayvanların 21’i (%35) kedi ve 39’u (%65) köpek olup, 30’u (%50) dişi ve 30’u (%50) erkekti. Radyolojik değerlendirmede, kedilerde vertebral kırık (n=12, %57), spondilozis deformans (n=3, %14) ve yabancı cisim (n=2 %10) belirlenirken; köpeklerde spondilozis deformans (n=25, %64), vertebral kırık (n=9, %24), dissemine idiopatik spinal hiperostoz (n=5, %13), diskospondilitis (n=4, %10), vertebral subluksasyon (n=2, %5) ve neoplazi (n=1, %3) tespit edildi. Sonuç: Kedi ve köpeklerde fiziksel, nörolojik ve radyolojik muayeneler ile birçok vertebra hastalığının tanısı konulmaktadır. İleri görüntüleme teknikleri ile karşılaştırıldığında her ne kadar radyolojik muayene iki boyutlu ve düşük tanısal detay verse de, anestezi gerektirmemesi ve maliyetin düşük olması nedeniyle halen daha en başta tercih edilmesi gereken bir yardımcı tanı yöntemidir.
