CT在犬鼻出血疾病诊断和鉴别诊断中的应用

Application of CT in the disease diagnosis and differential diagnosis of canine epistaxis

为了明确犬鼻出血的原因,了解鼻腔内受损的情况,对患犬进行CT检查从而对鼻出血疾病做出明确诊断。首先对表现为鼻出血的病犬进行常规的体格检查、实验室检查。然后对病犬进行镇静、麻醉,采用16排CT对病犬头部进行扫查,必要时采用碘海醇进行造影增强扫查。结果显示:在19例鼻出血病例中,确诊的主要疾病有口鼻瘘(5/19)、鼻腔肿瘤(3/19)、鼻部感染(2/19)、外伤(2/19)、鼻腔异物(1/19)和肉芽肿(1/19)。通过CT检查未确诊病因5例。本文分析了不同原因导致鼻出血病例的CT影像学特征,为临床上鼻出血病例的诊断和鉴别诊断提供可靠的参考资料。

In order to clarify the cause of canine epistaxis and identify the damage in the nasal cavity,CT examination was performed on the afflicted canines for clear diagnosis of the disease.Firstly,routine physical examination and laboratory examination were carried out in canines with epistaxis.Then,the animals were sedated and anesthetized.16-slice CT was used to scan their heads,and iohexol was used for contrast-enhanced scanning when necessary.The results showed that the diseases diagnosed in 19 cases of epistaxis were oronasal fistula(5/19),nasal tumors(3/19),nasal infection(2/19),trauma(2/19),nasal foreign body(1/19)and granuloma(1/19).CT examination did not confirm the etiology in 5 cases.and the above data provided reference for the disease diagnosis and differential diagnosis of epistaxis cases.
