Results suggest that the long-term outcome of ameroid constrictor occlusion of PSS in cats is poor. Owners of older cats and cats with preexisting neurologic signs should be made aware of the potential for a poor outcome when considering surgical correction of this disease.

Nonsurgical management of AAS by use of a cervical splint is a viable treatment modality for young dogs with a first episode of acute-onset clinical signs, regardless of the severity of neurologic deficits at admission.

TPA has no predictive value on clinical outcome in dogs treated with LST for stabilization of CrCL deficient stifles.

This report describes a 4 mo old intact male Akita that presented for evaluation of a life-long history of facial swelling and failure to thrive. Physical examination revealed an enlarged cranium with prominent bony swellings on the maxillary bone, excessive laxity and crepitus involving multiple joints, and proprioceptive deficits. Radiographs demonstrated multiple osseous abnormalities including endosteal thickening of the femurs and ilium. Necropsy revealed gross compression of the cerebellum and brainstem. Physical exam findings, radiographic abnormalities, and histopathology of multiple bony lesions were all consistent with craniomandibular osteopathy. In this unique case of craniomandibular osteopathy, the dog was affected with severe bony proliferations leading to generalized hyperostotic lesions and brainstem compression resulting in neurologic deficits.

A 14-year-old domestic shorthair cat presented with a 5-month history of urinary incontinence and inappro-priate elimination. Ultrasonography revealed a well-marginated, vascular mass of mixed echogenicity ex-tending from the dorsal wall of the urinary bladder into the lumen. Partial cystectomy was performed for re-moval of the urinary bladder mass; histopathological evaluation revealed a spindle cell neoplasm with a prominent palisading pattern. Histomorphologic features and immunohistochemical demonstration of vimentin, glial fibrillary acidic protein and S-100 protein, combined with negativity for smooth muscle actin and desmin were consistent with malignant peripheral nerve sheath tumour. This case report describes a novel location of malignant peripheral nerve sheath tumour; to the authors' knowledge, the bladder has not been described as a site of origin in the cat or any other domestic species.

The purpose of this study was to describe the appropriate surgical technique, postoperative monitoring, and complications encountered with use of vacuum-assisted closure (VAC) in six dogs with confirmed septic peritonitis. Initial diagnosis of septic peritonitis was performed by measuring either the blood-to-fluid lactate ratio and glucose concentration differences or cytologic verification of intracellular bacteria. After appropriate surgical procedures were performed to manage the primary cause of peritoneal sepsis, a VAC was performed. Serum and abdominal fluid protein levels were measured, and all complications were noted during the postoperative period. Three of the six dogs (50%) survived to the secondary closure and were subsequent discharged, which is similar to previous studies where the abdomen was either closed primarily or treated with open abdominal drainage. No major complications occurred with bandage management during hospitalization. The results of this study support VAC as a feasible technique for managing septic peritonitis.
