title: Lacerations of the ulnar artery: hemodynamic, ultrastructural, and compliance changes in the dog.
abstract: The hemodynamic and structural changes following single artery laceration were studied in the forelimbs of 25 adult dogs. Consistent back pressure in the distal ulnar artery stump was noted immediately and at 2 and 4 weeks. There were no significant changes in vessel compliance or vessel wall morphology of the proximal or distal stumps. The retrograde pressures of the distal arterial stump may contribute to the relatively high thrombosis rate following arterial repair in the forearm.
