Pre-existing pathomorphological changes in vessels of patients with traumatic finger abjunctions and wounds with a circular saw and a milling-machine

Introduction. There are no studies on vascular pathomorphological changes in persons constituting the risk group on the hand finger traumatic abjunctions and wounds in the available literature, although there is evidence suggesting a significant influence of this factor on the results of revascularizing reconstructive-and-restorative surgeries. Purpose. To reveal and analyze possible pre-existing vascular pathomorphological changes in persons with traumatic finger abjunctions and wounds with a circular saw and milling-machine. Materials and Methods. The authors investigated the operation material from 26 men with open injuries of the hand who engaged in mechanized physical labor and subjected to active or passive smoking using the methods of light microscopy of paraffin and epoxide semi-thin sections. Results. They determined the frequency (50 %) and the variants of obliterating arterial involvements of the hand fingers: adaptive neointimal hyperplasia, atherosclerosis, Hammer-syndrome, vasculites. The frequency of pathomorphological changes in vessels is reliably higher in patients above 30 comparing with those at the age from 22 to 30 years. Conclusion. A variety of arterial obliterating involvements of the hand fingers in patients from the risk group on the hand finger abjunctions and wounds evidences about the need to investigate operation material histologically. This approach will allow clarifying the outcome prognosis of revascularizing surgery, as well as the protocol of postoperative management of patients.
