ABSTRACT We observe delayed referrals to appropriate Microsurgery Unit Point and definitive treatment of traumatic limb amputations.Cases with wrist proximal amputations have a deadline for surgical replantation as these configure life-threatening injuries.Objective: To analyze patients with traumatic proximal wrist upper limb amputations with prolonged ischemic time who underwent temporary artery catheterization to assess stump viability and results.
Methods: A case-series study including all patients with a proximal wrist upper limb amputation and a cold ischemic time equal to or above six hours from 2017 to 2021.Results: In total, two surgeons operated eight patients who had experienced forearm amputation injuries.Median ischemia time totaled eight hours.
All patients required additional surgeries, most commonly split-thickness skin graft or fixation revision (three patients).This study obtained five successful macroreimplantations.The mean cold ischemia time was longer in the group with successful macroreimplantations (7.
4 hours) than of Table Place Name the unsuccessful group (9 hours).Conclusion: Macroreplantations require immediate referral to microsurgery and, although temporary artery catheterization helps surgical decision making, the technique seems to fail to influence outcomes.Level of Evidence IV, Retrospective Case Series.
