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.

This clip shows an examination of the lateral abdominal wall of a dog after a bite injury. The subcutaneous tissue is thickened and heterogeneous, with small intestinal loops visible just under the skin.
The same dog as in Abdominal wall injury (1). The muscular wall is interrupted. Through the gap, a small bowel loop is visible extending toward the subcutis.
This abscess was located in the soft tissues of the neck and shows a typical ultrasonographic appearance. The lesion is well marginated with a thick, irregular hyperechoic wall. It contains fluid with swirling echoes, indicating cells and/or debris.
This is a 12-year-old neutered female Whippet originally presented with a history of insidiously progressive ataxia and weakness in all four limbs and intermittent neck pain of approximately 6 months’ duration. For the past year, with monthly electro-acupuncture (EA) and twice-daily Chinese herbal medicine; she no longer has pain or quadriparesis and retains only an intermittent mild ataxia. Acupuncture needles (22 G, 25 mm) are inserted into classical acupoints Jian jia ji located above and below the transverse processes of the cervical vertebrae in the area of the cervical branches of the spinal nerves, as well as acupoints on the small intestine and gallbladder channels that transverse the neck. In the video, pairs of acupuncture needles can be seen connected via alligator clips and wires to an electronic acupunctoscope delivering 20 cycles/s (Hz) and 3 mA electricity for 15 minutes, and then 15 minutes alternating between 80 Hz and 120 Hz, 3 mA. The dog is also receiving EA on her lumbar region (L2–L3) and dry needle acupuncture (acupuncture needles with no electricity) of other acupoints of her back and thoracic and pelvic limbs to treat the underlying traditional Chinese veterinary medicine pattern that caused her initial signs. The dog is neither restrained nor sedated. After she adjusts to the slight tingling sensations and muscle contractions on her neck muscles, she lays her head down and rests quietly. Many dogs sleep during their acupuncture session. (See pages 502 and 505 in the Manual)
Clip of acute pancreatitis in an 11-year-old Jack Russell Terrier presented with a history of recent onset vomiting and abdominal pain. The transducer was initially placed in transverse orientation on the right cranial abdomen and then turned into a sagittal orientation. The right lobe (RL) of the pancreas seen next to the descending duodenum (DUOD) is thickened, diffusely hypoechoic and surrounded by hyperattenuating fat. Focal abdominal effusion (EFF) is also present. The duodenum contains a small amount of fluid and shows decreased peristalsis during the examination. On sagittal images the pancreas has a ‘tiger stripe’ appearance, consistent with pancreatic oedema secondary to pancreatitis. The authors would like to thank Dr George Henry (University of Tennesse) for his assistance with video post-processing and editing.
Aortic thromboembolism is a relatively common complication of feline hypertrophic cardiomyopathy. In dogs, it is much less common and generally no underlying cardiac condition is found in these cases. There may be a breed predisposition for the Cavalier King Charles Spaniel and an association with Cushing's syndrome and hypercoagulable status has been suspected. The embolism of the iliac bifurcation can be subtle, causing mild, uni- or bilateral weakness, or severe, causing complete bilateral paralysis of the hindlimbs; this may be reversible if enough collateral circulation resumes the oxygen provision to the legs or may remain irreversible in a number of cases.
As the clip begins, the time–gain compensation (TGC) controls have been set wrongly, resulting in very dark superficial and deep bands, and a very bright middle band. When the ‘image optimizer’ is applied the optimal settings are restored without touching the TGC controls.
Oblique echocardiographic views looking at the left atrium in the Domestic Shorthair cat featured in Figure 2 of the article. A mobile thrombus is present, moving around the left atrium and posing an extremely high risk of sudden death or arterial thromboembolism.
Under general anaesthesia, the dog is placed in right lateral recumbency if the operator is right handed. An area of skin is prepared for a sterile procedure. The head of the dog is flexed at approximately 90 degrees to the cervical spine. The operator palpates the appropriate landmarks (the wings of the first cervical vertebra and the occipital protuberance) which act as a guide for the point of insertion of the needle. The spinal needle is inserted through the skin perpendicular to the spinal column and horizontal to the table surface. Once through the skin and soft tissues, the stylet of the needle can be removed. The needle is then advanced, 1 mm at a time, until a ‘flash’ of fluid appears in the hub of the needle. The fluid is allowed to drip into a sterile polypropylene container until approximately 0.5 ml is collected. (See page 47 in the Manual)
The right atrium and ventricle are at the top of the screen, with the left atrium and ventricle below. The left atrium is markedly dilated secondary to mitral valve regurgitation. Left-to-right flow of blood across an ostium secundum ASD is demonstrated by colour flow Doppler.
