“…Clinical signs usually reflect a forebrain disorder and include obtundation, behavior abnormalities, difficulty in house training, decreased vision or blindness, circling, pacing, restlessness, and seizure activity. Affected dogs predominantly present with enlarged lateral as well as third ventricles, although distension of the 4th ventricle also has been described . The purpose of ventriculoperitoneal shunt (VPS) surgery is to allow CSF flow through a shunting mechanism from the intracranial ventricles to the peritoneum.…”

Background Several case series and case reports have been published about idiopathic hydrocephalus treatment in dogs and cats using ventriculoperitoneal shunts (VPS). Objectives To determine the risk and type of complications in dogs and cats after VPS placement. Animals Sixteen papers were included. Sixty dogs and 13 cats with idiopathic hydrocephalus treated by VPS placement were identified. Methods The databases CAB, Scopus, and Medline were used. Idiopathic/congenital hydrocephalus, feline/canine patients, ventriculoperitoneal shunting, complications, and outcomes were inclusion criteria. The focus was on complication type and time frame within which they arose. Results Complications in dogs (n = 60) were shunt obstruction (6/60; 10%), pain (4/60; 5.5%), shunt infection (3/60; 4.1%), disconnection (3/60; 4.1%), excessive shunting (2/60; 2.7%), and kinking (1/60; 1.6%). Complications in cats (n = 13) were coiling of the shunt in the SC tissue (2/13; 15.4%); kinking (1/13; 7.7%); and shunt obstruction (1/13; 7.7%). Complications were most likely during the first 6 months after shunt placement. Conclusion and Clinical Importance Ventriculoperitoneal shunting is considered a viable treatment option for patients with hydrocephalus. Potential complications should be discussed with the owner. Early diagnosis of complications is essential.

“…Authors from Greece and the USA describe two dogs that developed hydrocephalus following obstruction of the lateral apertures in the brain. 6 Although they could not positively identify a cause, they suggest empirically that it followed on from some change in the choroid plexus, which altered the outflow of the CSF. They show the MRI, histopathology of the choroid plexus and line diagrams of the anatomy to tie the different aspects of the case together.…”

“…O LCR é produzido em uma taxa constante, principalmente pelos plexos coroidais, circulando através do sistema ventricular para o espaço subaracnóideo, onde é absorvido por vilosidades aracnóides, sendo esse, seu principal local de absorção. Uma das principais desordens associadas ao líquido cefalorraquidiano é a hidrocefalia, ocasionando o aumento de volume no interior do cérebro (KARTAL; ALGIN, 2014;KENT et al, 2016;SÁNCHEZ;AMORIM, 2015;THOMAS, 2010;TRINDADE et al, 2019).…”

The objective of this study was to describe the use of complementary imaging tests to aid diagnosis in cases of hydrocephalus in the canine species. A female canine, of the Shih-Tzu breed, approximately three months old, weighing 2 kg, was seen at the Unicentro veterinary school clinic, with the main complaint of not playing and not responding to auditory or visual stimuli. The patient had pain when palpated in the cranial region, as well as pain in the topography of the cervical spine. The animal was sent for imaging exam. On radiographic examination, an enlarged skull was observed with soft tissue radiopacity in the frontal bone area, associated with bone discontinuity in the anatomical topography of the frontal fontanelles. On transcranial ultrasound, anechoic areas located inside the brain were detected, as well as an increase in the dimensions of the lateral ventricles filled with anechoic content. The report was indicative of hydrocephalus. The present study showed the effectiveness of transcranial ultrasound examination and cranial radiographic examination in diagnosing hydrocephalus. Being an alternative to veterinarians, since computed tomography and magnetic resonance imaging are high-cost exams and these methods are often unavailable, depending on the region.
