title: Fibromuscular proliferation in finger arteries after hand replantation: a case report.
abstract: We report on a case where a digit of a previously replanted hand was amputated 3 years after injury. Histologically, the finger arteries demonstrated a marked intimal thickening due to fibromuscular proliferation, with narrowing of the lumen. The media showed muscular hyperplasia and fibrosis, whereas the adventitia was normal. These changes are probably a consequence of ischemia and reperfusion injury and might explain the persistent vasomotor insufficiency found in replantation patients.
