Should the artery be trimmed before anastomosis in every finger replantation/revascularization case? Prospective, single-center, multidisciplinary study over 46 months.

Introduction: Despite optimal arterial anastomosis, some finger replantations fail. Our objective was to evaluate how the mechanism of injury (MOI) affects the artery's microscopic appearance and the success of anastomosis. We hypothesized that the MOI influences arterial histology and microsurgical success.
