Abstract

Objective: To demonstrate that ultrasound-guided femoral artery catheterization is feasible and practical in dogs.

Case series summary: Four female mixed breed dogs weighing 14–23 kg were used following a terminal junior surgery laboratory and had been anesthetized before the ultrasound study. Dogs were positioned in lateral recumbency with the upper limb abducted and immobilized. The dependent limb was extended and shaved and isopropyl alcohol was applied. An ultrasound transducer was oriented transverse to the axis of the limb and, following ultrasonographic identification, the femoral artery was cannulated and a catheter was placed using the Seldinger technique. Ultrasound-guided catheterization was successful in 9 of 10 attempts; cannulization was successful in 10 of 10 attempts. Procedure time improved from 10 minutes to 1 minute during practice. Each of the 2 investigators was able to simultaneously ultrasound and cannulate the vessel. The major complication was hematoma formation, which occurred regardless of success.

Information provided: Ultrasound-guided femoral artery catheterization is feasible and relatively easy to master in medium-size, anesthetized dogs.
