Nonselective computed tomography angiography for detecting arterial blood flow to the distal limb following trauma in two small equids

Two equids weighing <250 kg were examined several days after suffering severe mid-diaphyseal dorsal metatarsal lacerations. Distal limb vascular disruption was suspected in both cases. Nonselective computed tomography angiography with contrast medium injected peripherally via the jugular veins was used to evaluate the vascular supply to the distal limb. The use of this imaging technique demonstrated either intact or disrupted distal limb vasculature. The imaging results were verified with a positive long-term outcome in the case with a diagnosis of an intact vasculature and with histological findings of avascular necrosis in the case with a diagnosis of disrupted vasculature.
