Contrast enhanced computed tomography assessment of superficial inguinal lymph node metastasis in canine mammary gland tumors.

Mammary gland neoplasms are predominant in dogs. However, sentinel lymph node (SLN) status assessment criteria have not been established for these cases. In this retrospective, secondary analysis, diagnostic case control study, CT images of 65 superficial inguinal SLNs were obtained before and 1, 3, 5, and 10 min after intravenous administration of contrast agent (iopamidol 370 mgI/mL).

Upper Airway Injury in Dogs Secondary to Trauma: 10 Dogs (2000-2011).

Ten dogs that presented with trauma-induced upper airway rupture or stenosis were reviewed. Tracheal rupture was seen in seven dogs, tracheal stenosis in one dog, and laryngeal rupture in two dogs. Clinical abnormalities included respiratory distress in five dogs, subcutaneous emphysema in eight, air leakage through the cervical wound in seven, stridor in three dogs, pneumomediastinum in four and pneumothorax in one dog.

Spontaneous urethral catheter kinking or knotting in male dogs: four cases.

Four dogs were diagnosed with urethral catheter malfunction. The catheter was kinked in three dogs and knotted in one dog. In two dogs, kinking of the catheter was associated with presence of urethroliths in the perineal urethra.
