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.

Rhythmical contractions of the dog's left flank.
Fluoroscopy images from a lateral projection showing the diaphragm contracting in time with the heartbeat.
Fluoroscopy images from a dorso-ventral projection showing the left crus of the diaphragm contracting in time with the heartbeat.
Cockatiel with dyspnoea. Dyspnoeic birds often show a characteristic tail bob, which is an exacerbated vertical motion of the bird’s tail whereby the tail is pressed ventrally; this movement can be compared to abdominal breathing in mammals. © Yvonne van Zeeland, Utrecht University
A 9-month-old male mixed-breed dog, which had been neutered 2 weeks prior to this video clip. The dog had developed a stiff gait and dysphagia since surgery. Note the classic facial expression (risus sardonicus) associated with tetanus, with the ears drawn up. When the dog was placed on its side, it developed a dramatic increase in extensor tone in all four limbs, resulting in the typical sawhorse stance. (See page 286 in the Manual)
Thoracic duct ligation with haemoclips
Normal B-mode 2D ultrasound clip displaying glide sign as evidence of apposition of the visceral and parietal pleura.
Absence of a glide sign, i.e. no lateral shimmering as evidence of apposition of the two pleura, and hence supports a pneumothorax at this site.
Small volume pleural fluid. Here you see free pleural fluid immediately cranial to the heart at the beginning of the clip, and fluid between the heart and the diagphragm at the end when the liver is in view on the left-hand side.
B-lines are defined as hyperechoic lines originating at the PP interface, extending to the far field, obliterating the normal A-lines and moving with inspiration and expiration.
One 'B-line' identified on thoracic POCUS of a dog without any relevant respiratory disease.
A 'hepatized' portion of lung with a fluid-filled 'bronchogram' visualized.
A 'hepatized' portion of lung with aerated lung distally, manifesting as a ragged, hyperechoic margin.
Pericardial effusion in short axis from the right-hand side.
The ultrasound beam is fanned upwards through the short axis of the heart from the right-hand side, with marker facing caudally. This clip represents the schematic from Figure 7 of this article.
Left atrial thrombus in a cat with an aortic thromboembolism.
A narrow left ventricular lumen, which is obliterated with every heartbeat, consistent with a hypercontractile left ventricle in a state of hypovolaemia. This is a right-sided, short-axis view as described in Figure 7 and Video 9 (part I) of the article.
Hypocontractile ventricle.
The tibia, in the cranial cruciate ligament-deficient stifle, will subluxate cranially relative to a motionless femur. This results in passive cranial motion of the index finger overlying the tibial tuberosity as seen in this video. A positive result is recognized as an increase in the distance between index finger and thumb as the proximal tibia moves cranially with respect to the distal femur.
A 3-year-old neutered Pomeranian bitch presented with a 24-hour history of non-ambulatory flaccid tetraparesis with reduced spinal reflexes. Careful inspection of the dog identified a tick. Removal of the tick resulted in a rapid improvement within 24 hours. (See page 296 in the Manual)
