“…BN can lead to increased intracranial pressure (ICP) owing to its primary (space-occupying) or secondary (edema) effects (Kornegay et al 1983, Snyder et al 2006, Terlizzi & Platt 2006, Walmsley et al 2006, Lewis et al 2016. The ICP value in normal dogs' ranges from 5 to 12mmHg (Dewey & Fletcher 2016) and is considered high when the value is greater than 13mmHg (Seki et al 2019). Though ICP measurement can be performed by direct means, such as intracranial optical fibers (Bagley et al 1995), subdural and intraparenchymal transducers (Sturges et al 2019Seki et al 2019) and indirect transcranial Doppler (Fukushima et al 2000), due to the difficulty and high cost, they are rarely performed in routine neurological practice (Terlizzi & Platt 2006, Seki et al 2019).…”

Cerebrospinal fluid (CSF) collection in dogs with brain neoplasms (BN) may be associated with complications owing to increased intracranial pressure caused by expansive lesions. Although this procedure has been performed in dogs with BN, no data regarding complications after CSF tap in these animals is available. Thus, this retrospective study aimed to identify the rate and types of complications observed after CSF taps in dogs with BN. Thirty dogs with BN were included in the study. In 83% (25/30) of the cases, clinical recovery after CSF tap was considered normal, and in 17% (5/30) the recovery was abnormal. The main clinical and neurological signs observed in dogs with abnormal clinical recovery were apnea (5/5), absence of pupillary photomotor reflex (3/5), coma (2/5), and stupor (1/5). In 40% (2/5) of the dogs, herniation of the cerebellum through the foramen magnum was observed on necropsy. In conclusion, the rate of complications after CSF taps was 17%, and was characterized by apnea, absent pupillary photomotor reflex, altered level of consciousness, and encephalic herniation.
