Video library
Welcome to the BSAVA Video Library. This page gathers together all the clinical videos that are published alongside our manual chapters and Companion articles. If you have access to the source content you will be able to play the video from this page, as long as you are logged in. If you do not have access, clicking on the video title will take you to the source article or chapter. You can either use a library pass, or buy the chapter or article, to gain access to all the videos and the full text of that chapter or article. Please note that library passes cannot be used on Companion articles - BSAVA members already have access to Companion. Alternatively you can buy the entire book to gain access to all the videos in that book. You can use the filters on the left to focus on your topics of interest and you can also search the site and filter by content type=video. Please contact us with any feedback or suggestions.

A Border Terrier collapsing and exhibiting increased muscle tone and hyperkinetic movements. This condition is colloquially termed canine epileptoid cramping syndrome. (See page 248 in the Manual)
Video sequence recorded from an Alicam® videoendoscopy capsule, showing a bleeding gastric polyp.
Cardiomyopathy in a 6-year old Exotic Shorthair cat – right parasternal short-axis echocardiographic view at the level of the aortic root. Severe left atrial dilation and poor left atrial contractility can be seen, as can dense spontaneous echocontrast (‘smoke’) within the left atrium.
The endoscope in a j-flexed position looking at the lower oesophageal sphincter (abnormally dilated) in a patient presenting with chronic vomiting. A case of sliding hiatal hernia.
An 8-year-old neutered Dobermann bitch showing the disconnected gait typical with a caudal cervical lesion. The thoracic limb gait is short, choppy, and at times the dog appears lame. The pelvic limb gait is ataxic with long strides. The dog is also exhibiting signs of cervical pain. Note the atrophy of the supraspinatus and infraspinatus muscles, causing the scapula spine to be prominent. (See page 276 in the Manual)
Cavaletti rails are available commercially or may be homemade using polyvinyl chloride (PVC) rods, which are inserted into holes predrilled at various heights into traffic cones. When using cavaletti rails, the rails should be placed at a height that is feasible, yet challenging, for the patient to clear at a walking pace. The clip shows a dog being walked at a pace that allows the rails to be cleared with mild effort. As the strength and coordination of the patient improves, the rails should be elevated to continuously offer a feasible challenge. (See page 494 in the Manual)
(a) Head and body tilt. Adult miniature Dachshund demonstrating a left head tilt, and left truncal deviation on being held. The dog also prefers to lie with the left side down and becomes distressed when held with the left side uppermost. Testing of the righting reflex (when a dog is held horizontally the normal response is to reach upwards or right itself). The righting reflex is lost when the dog is held with the left side down. These combination of clinical signs indicate left vestibular syndrome.
(b) Proprioceptive placing. Testing of proprioceptive placing using tactile placing response testing. There is loss of tactile placing in the left thoracic and pelvic limbs. When combined with the left vestibular syndrome in the previous video clip this is indicative of central left vestibular syndrome.
(c) Strabismus. Ventrolateral strabismus of the left eye indicative of left vestibular syndrome. The strabismus becomes more obvious if the head is moved from the left head tilt position to horizontal. There is also an intermittent pathological vertical nystagmus, but this is less obvious on the basis of the video clip.
(d) Sensory testing. Loss of sensation of the inner nasal mucosa suggestive of a lesion affecting the ophthalmic branch of the trigeminal nerve (the ophthalmic branch innervates the nasal mucosa, while the nasal planum is innervated by the maxillary branch of the trigeminal nerve). The dog also demonstrates a fluorescein-positive corneal ulcer within the central region of the cornea with no evidence of a painful eye, which is also consistent with damage to the ophthalmic branch of the trigeminal nerve. The presence of a left trigeminal nerve lesion in addition to the left vestibular syndrome is further evidence of a central left vestibular lesion. (See page 188 in the Manual)
This clip shows a dog with cerebellar ataxia. Note the marked hypermetric gait in all four limbs as well as head incoordination. It is important to note that this dog is not showing any signs of paresis, which is consistent with generalized truncal and head ataxia as a result of a cerebellar lesion. (See page 7 in the Manual)
A 5-year-old neutered Beagle bitch with a herniated disc at C4–C5. The dog has severe neck pain, resulting in reluctance to move the neck. The head is held low due to kyphosis of the thoracolumbar spine. The sclera are visible as the animal attempts to look at the videographer without moving the neck. The dog also has obvious muscle spasms causing the ears to twitch. The dog has mild ataxia in the pelvic limbs and a short-stilted gait in the thoracic limbs. When standing, the dog tends to lift the left thoracic limb due to a nerve root signature. (See page 279 in the Manual)
This clip shows hyperechoic mesentery adjacent to a mass associated with the pancreas in a cat with lymphosarcoma. Such changes may be associated with inflammation or with diffuse neoplastic infiltration. A section of the duodenum is seen at the top left-hand side of the image.
The acoustic output of the unit is altered during this clip. This can be followed in the upper right-hand corner of the image, where the output power is displayed as a percentage. Note the decrease in overall brightness and the lost of image information as the power is decreased.
The overall gain is changed during this clip. The gain level is displayed in the lower left part of the image, denoted by ‘G’. Note the overall increase in image brightness, leading to increased noise due to over sampling, as the gain is increased.
At the right of the image, small green arrowheads are visible showing the focal zone(s). At the start of this clip, one focal zone is selected, then later two focal zones are chosen. Note the decrease in frame rate (shown at the top right-hand corner of the image) as soon as two focal zones are selected.
Cholecystocentesis in a cat using a percutaneous spinal needle.
Clip of chronic pancreatitis in a 16-year-old Domestic Shorthaired cat. The transducer was placed on the mid-cranial abdomen in transverse orientation. Vascular landmarks include the portal vein (PV) and splenic vein (SV). The pancreas is more conspicuous than in a normal cat (compare with Normal pancreas (cat) clip). The left lobe (LL) and body (B) of the pancreas are hypoechoic in comparison with the surrounding mesenteric fat and have irregular margins. The left lobe of the pancreas is thickened and the pancreatic duct (PD) is irregularly dilated (up to 0.25 cm). The authors would like to thank Dr George Henry (University of Tennesse) for his assistance with video post-processing and editing.
The right kidney of an elderly cat with azotaemia is shown in this clip. Although the kidney is a reasonably normal size, the margins are mildly irregular and rather indistinct. Corticomedullary definition is present but is subjectively reduced. (Courtesy of F. Barr)
