Practical small animal ultrasound bits and pieces: part II…. tracheal exudate sign

And the same in video: This is a useful finding: it implies airway exudate. If you see this in a coughing patient and transthoracic lung ultrasound is unremarkable, there is likely significant airway disease. Differential diagnoses associated with this might include, for example, eosinophilic bronchopneumopathy, infectious tracheo-bronchitis, bleeding due to coagulopathy, bronchial foreign body. Also … Continue reading

Practical small animal ultrasound bits and pieces: part I…linear foreign bodies

Linear FBs are sometimes difficult to visualise convincingly: even when everything is plicated to hell. OK, now see what happens if you fan the probe over the suspect loop of gut… …like magic! There it is. One more still from the same cat. We know the linear FB is there: … Continue reading

Should we recommend CT angiography for all potential portosystemic shunts -or is ultrasound good enough? Part I: extra-hepatic shunts

In all images here cranial is to left of image. I’ve listened to two authoritative presentations on shunts by specialist surgeons in the last month. To paraphrase, both of them said they recommend CT angio and find ultrasound too user-dependent and too unreliable. My impression is that there’s a general drift in this direction. I … Continue reading

Lung ultrasound in cats and dogs: why does it get such a varied reception? Things become clearer

My impression, from a UK veterinary perspective, is that lung ultrasound (LUS) gets variable press. Specifically, most specialist cardiologists don’t much care for it. It’s useful to understand why this is. It’s no coincidence that LUS was discovered and developed primarily by human acute care physicians in intensive care units (ICUs) and emergency departments. Looking … Continue reading

Sonography of canine interstitial lung disease: some examples

Firstly, a young CKCS with PCR +ve Pneumocystis pneumonia: this dog had a history of masticatory muscle myositis managed successfully with chronic steroid therapy until he recently developed severely increased respiratory effort. There are widespread lines perpendicular to the pleurae. As discussed in previous posts, the appearance of abnormal lung lines on ultrasound is … Continue reading

Intra-operative ultrasound: utility in intrahepatic shunt attenuation in dogs

Pneumonia in dogs: gastrointestinal presenting signs

With the advent of lung ultrasound and the resulting great leap forward in our ability to diagnose bronchopneumonia relatively easily and with good specificity has opened a door on its true incidence and the spectrum of associated presenting signs. Notably, we now see affected dogs in which gastrointestinal signs are prominent. It’s hard to prove … Continue reading

Lung ultrasound in small animals: late 2021 update

As I might have said before, lung ultrasound is the gift that keeps on giving. In the beginning lung ultrasound wasn’t even a thing; then it became all the rage and we recognised some fundamental patterns. With time we’ve worked out some more subtleties and developed new understanding of concepts that we previously thought we … Continue reading

Sonography of the healthy feline jejuno-ileal junction

This is a very niche observation but something that I’ve not seen described elsewhere. In cats without any evidence of gastrointestinal disease there is often an asymmetrical thickening of the small intestinal mucosa at the jejuno-ileal junction. This is located between 1.5 – 4.0cm proximal to the ileo-caeco-colic junction. https://www.cabdirect.org/cabdirect/abstract/20123064781 Before I realised that this … Continue reading
