Intra-arterial catheterization
We mostly scanned the left forelimb; however, when catheterization in
the left was unavailable, we scanned the right forelimb in left lateral
recumbency due to facility limitations − five of fifty-four CT scans. In
the first phase, after one CT scan, one horse experienced damage to the
left artery; however, ultrasound during the second phase revealed
recovery of the artery after three months. In the second phase,
ultrasonography identified a damaged left medial palmar artery after a
CT scan of 300 mg I/s of IDR at a rate of 6 mL/s, wherein the maximal
pressure was 118 psi. The horse showed no soft-tissue edema or lameness
following CT scans. The other horses did not show any complications
associated with intra-arterial catheterization.
