Clinical data for 22 dogs suspected suture-reactive granuloma following ovariohysterectomy were reviewed to evaluate the epidemiology, treatment and long-term prognosis. Fifteen (68%) of 22 dogs were miniature dachshund. The median age at diagnosis and the interval from ovariohysterectomy to the diagnosis was 3.5 (1.1-9.3) years old and 2 (0.3-4.3) years, respectively. Commonly clinical signs were depression, anorexia, weight loss and fever (13/22). An increasing of plasma C-reactive protein (CRP) concentration was noted in 14 (82%) of 17 examined dogs. Intraabdominal granulomas were completely excised in 20 of 22 dogs. Suture materials were grossly and/or histopathologically confirmed in 16 of 20 cases. A favorable outcome was achieved in 8 (42%) of 19 dogs except of one dog dying perioperatively of renal failure. However, a recurrence or another disease such as granulomatous gastroenteritis, panniculitis, or sterile granuloma, was represented in each of 11 dogs. Ten of these dogs were miniature dachshund. The results of this study suggest that the risk of occurrence of intraabdominal granuloma after ovariohysterectomy was higher in miniature dachshund and the dogs with the granuloma have the risk of occurrence of another granulomatous inflammatory disease after completely surgical excision of the granuloma.

Cerebrospinal fluid pressure (CSFP) in the cervix and lumbar spine was measured percutaneously using a fiberoptic pressure monitor in 28 healthy dogs without neurological abnormalities. The cervical CSFP (C-CSFP) ranged from 2.0 to 12.0 mmHg and its mean was 6.11 mmHg, while the lumber CSFP (L-CSFP) ranged from 2.0 mmHg to 12.0 mmHg and its mean was 5.93 mmHg. The ranges of C-CSFP and L-CSFP were similar. The mean arterial blood pressure (BP) increased from 127.5 ± 14.1 mmHg to 203.9 ± 33.3 mmHg immediately after epinephrine administration, then returned to 122.7 ± 25 mmHg at 30 min after epinephrine administration. The mean C-CSFP was 8.4 ± 3.4 before epinephrine administration, 10.0 ± 5.1 and 9.4 ± 4.8 mmHg at 0 and 30 min after epinephrine administration, respectively. However, the mean L-CSFP was 4.4 ± 2.8 before epinephrine administration, 4.6 ± 5.7 and 5.6 ± 5.0 mmHg at 0 and 30 min after epinephrine administration, respectively. There was no correlation among C-CSFP, L-CSFP, and arterial BP. This study demonstrated that the percutaneous fiberoptic catheter method allows stable and continuous monitoring of CSFP in the spinal canal in dogs.
