The signalment, history, clinical signs, radiographic findings, and surgical findings of 25 consecutive animals that had sinography were reviewed to assess the contribution made by sinography to diagnosing and surgically managing draining tracts in small animals. There were 23 dogs and 2 cats; a variety of breeds and both sexes were represented (18 males, 7 females). Before referral the mean duration of clinical signs was 9.8 months (range, 0.5 to 33 months) and a mean of 2.0 surgical procedures (range, 1 to 5) had been performed. Sinuses occurred in a variety of locations, most commonly the neck (10), head (6), and paws (5). The most common cause was foreign body (15). Survey radiographs showed abnormalities in 21 of 26 (78%) instances, including soft-tissue swelling (11), chronic-appearing periosteal reaction on adjacent bones (5), possible foreign body (4), and gas in soft tissues (2). Sinography (or fistulography) enabled definite diagnosis of the cause of the sinus (or fistula) in 15 of 26 (58%) instances and demonstrated 13 of 15 foreign bodies (sensitivity 87%; specificity 100%). Tracts caused by an esophageal perforation and otitis media were also correctly shown by fistulography. In 11 animals, sinography indicated that the position or extent of the lesion was different to that expected on the basis of clinical signs and survey radiographs.
回顾了连续25只接受窦道造影术的动物的信号、病史、临床症状、影像学检查结果和手术发现，以评估窦道造影术对小动物引流道诊断和手术处理的贡献。其中有23只狗和2只猫；涵盖了各种品种和性别（18只雄性，7只雌性）。转诊前临床症状的平均持续时间为9.8个月（范围为0.5至33个月），平均进行了2.0次手术（范围为1至5次）。窦道发生在多个部位，最常见于颈部（10例）、头部（6例）和爪子（5例）。最常见的原因是异物（15例）。26例中有21例（78%）的X线平片显示异常，包括软组织肿胀（11例）、相邻骨骼上出现慢性骨膜反应（5例）、可能的异物（4例）和软组织内气体（2例）。窦道造影术（或瘘管造影术）在26例中有15例（58%）能够明确诊断窦道（或瘘管）的病因，并显示出15个异物中的13个（敏感性87%；特异性100%）。由食管穿孔和中耳炎引起的瘘管也通过瘘管造影术正确显示。在11只动物中，窦道造影术显示病变的位置或范围与基于临床症状和X线平片预期的不同。
