“…At present, surgery is considered the treatment of choice. 4,[8][9][10][11][12] However, the overall prognosis for surgical management of canine PNSTs involving the brachial plexus or its roots is deemed unsatisfactory, with a median survival time of 12 months in dogs affected by plexus tumours and of 5 months for root tumours. 5 Tumour recurrence occurs in 78% of cases, with a relapse-free interval of 7.5 months for surgically treated dogs for plexus tumours and of 1 month for plexus and root tumours.…”

Objective: Treatment of canine peripheral nerve sheath tumours (PNSTs) is challenging and prognosis after surgical resection is considered poor. The aim of this study was to evaluate the feasibility and effectiveness of stereotactic radiotherapy (RT) of these tumours. Methods: 10 dogs with clinical symptoms and MRI findings consistent with PNSTs of the brachial plexus, branches and nerve roots were treated with linear accelerator-based volumetric-modulated arc radiotherapy (VMAT) with a dose of 35 Gy/5 fractions. Clinical and MRI follow-up examinations were planned and radiotoxicity and survival times were investigated. Results: Tumours involved the plexus and proximal nerves in three dogs, the plexus, proximal nerves and nerve roots in five dogs and the nerve roots and proximal nerves in two dogs. Partial response and partial or complete reductions of neurological deficits were observed in all the treated dogs. Local recurrence was observed in 9/10 of treated dogs. No symptom directly referable to radiotoxicity was observed. Mean overall survival of 371 6 30 days [95% confidence interval (CI) of (315-427)] and mean progression-free survival of 240 6 30 days (95% CI of 188-291) from this work are comparable with surgical literature data regarding the plexus and proximal nerve localization, but are superior in comparison with nerve root localization. Conclusion: VMAT can be a safe and viable alternative to surgery in cases of canine brachial plexus PNSTs involving the proximal nerves and nerve roots. Advances in knowledge: To our knowledge, this is the first prospective observational clinical study regarding VMAT stereotactic RT treatment for canine brachial plexus PNSTs and suggests that VMAT may achieve at least similar clinical outcome than surgery in a safer way.

“…Pathological changes to the brachial plexus in small animal medicine include inflammatory, neoplastic and, most frequently, traumatic conditions, such as road traffic accidents (Wheeler et al, 1986). Brachial plexus trauma occurs when there is traction of the thoracic limb or severe abduction of the scapula (Griffiths, 1974;Steinberg, 1988). Typically, the nerve roots are more likely to be damaged than the plexus itself due to a lower capacity to stretch (Griffiths, 1974;Holtzer et al, 2002;Dewey, 2003).…”

Brachial plexus trauma is a common clinical entity in small animal practice and prognostic indicators are essential early in the course of the disease. Magnetic stimulation of the radial nerve and consequent recording of the magnetic motor evoked potential (MMEP) was examined in 36 dogs and 17 cats with unilateral brachial plexus trauma.Absence of deep pain perception (DPP), ipsilateral loss of panniculus reflex, partial Horner's syndrome and a poor response to MMEP were related to the clinical outcome in 29 of the dogs and 13 of the cats. For all animals, a significant difference was found in MMEP between the normal and the affected limb. Absence of DPP and unilateral loss of the panniculus reflex were indicative of an unsuccessful outcome in dogs. Additionally, the inability to evoke a MMEP was associated with an unsuccessful outcome in all animals. It was concluded that magnetic stimulation of the radial nerve in dogs and cats with brachial plexus trauma may provide an additional diagnostic and prognostic tool.

One kitten and three adult dogs were admitted with a history of an acute or progressive lower motor neuron disease involving asymmetrically the thoracic limbs. Neurogenic muscular atrophy was also present affecting the relevant muscles in all the animals. As no other neuromuscular abnormalities could be detected on physical, radiological and clinicopathologic examination, a tentative diagnosis of brachial plexus neuropathy or neuritis was made. In the cat diagnosis was confirmed by electrophysiological testing demonstrating decreased sensory conduction velocity of the ulnar nerve and denervation potentials. The administration of prednisolone at antiinflammatory dosage for 3 weeks abolished or decreased the severity of the clinical signs in all the cases. Recurrence of the disease, one to 6 months after the cessation of treatment, was detected or reported for the 3 dogs where a follow-up was possible.
