A boxer dog with chronic hypertrophic gastritis resembling Menetrier's disease in man.

Chronic hypertrophic gastritis in a 7-year-old Boxer dog is described. This gastritis resembles Menetrier's disease in man. The dog was emaciated, lethargic, vomiting and had a poor appetite over a 4-month period. There was anaemia, and the blood smear was characterized by hypochromasia, strong anisoplania and striking poikilocytosis. There was a protein loss and at a later stage of the disease, a hypoalbuminaemia. On gastroscopic examination the plicae gastricae were numerous and strongly marked; moreover, they were granulated with numerous small haemorrhages. Radiographically, the stomach had a marked folding, primarily at the greater curvature. The passage of contrast medium from the stomach into the duodenum was strongly retarded. The pathological findings included macroscopical folding caused by local gland cell hyperplasia in the body as well as the pylorus, foveolar hyperplasia and, in the fundus and in the corpus near the greater curvature, folding of the muscularis mucosae and the submucosa. A superficial gastritis was found particularly in the fundus and corpus, whereas the pyloric antrum showed a more diffuse inflammation.

Vertebral body deformation causing Wobbler syndrome in a Great Dane.

This paper reports a case of cervical vertebral body deformation with gradually worsening posterior paresis in a Great Dane. The ventrocranial part of the body of the seventh cervical vertebra was severely eroded and deformed. This vertebra was tilted in relation to the sixth cervical vertebra producing a stenosis of the spinal canal which was demonstrated by myelography. Spondylolisthesis of the second type of G e a r y's classification was diagnosed. 99mTc-polyphosphate showed no concentration in the affected vertebra as would be found where bony tissues of different maturities are present, indicating the lack of effective repair. Dorsal hemilaminectomy resulted in no improvement.

Transcatheter closure of patent ductus arteriosus using occluding spring coils.

The purpose of this study is to report our initial experience with the use of spring coils to close the patent ductus arteriosus in the dog. There are few large-patient series reported in the veterinary literature. Coil closure was attempted in 15 dogs (median weight, 6.5 kg; range, 1.2 to 38.7 kg) presenting with a patent ductus arteriosus between May 1997 and May 1999. Arterial catheterization followed by angiography was used to decide if coil placement was adequate. A 5- or 8-mm embolization coil, depending on the angiographic diameter of the ductus, was delivered, with 1 loop in the pulmonary arterial side and the remainder of the coil in the aortic side of the duct. Additional coils were used if a residual shunt was present, and closure was confirmed by aortography. Patients were discharged the day after the procedure. Successful coil closure, without residual shunt on angiography, was achieved in 11 of 13 dogs in which coils were released. In 6 dogs, a coil embolized to the pulmonary artery. Four of these dogs had successful closure with multiple coils, and 2 others had surgery. None of these dogs experienced adverse effects. In 2 dogs with conical patent ductus arteriosus >5 mm in minimal diameter, coil closure was not done. We conclude that the patent ductus arteriosus size and anatomical shape are crucial in deciding whether coil closure is the method of choice. In selected cases, coil closure represents an elegant alternative to surgical ligation. Although pulmonary embolism occurred commonly, it did not cause any obvious clinical problem.
