Supermicroscopy and arterio-venolization for digit replantation in young children after traumatic amputation: Two case reports

BACKGROUND To report the application of supermicroscopy combined with arterio-venolization without venous anastomosis for replantation of digits following traumatic amputation in young children.CASE SUMMARY In March 2016, we treated two children aged 2 years and 7 years with traumatic digit amputation, no venous anastomosis, and bilateral digital inherent arteries on the palmar side. Supermicroscopy combined with an arteriovenous technique was adopted to improve the replantation surgery. Postoperative management involved auxiliary treatments such as anticoagulation, composure, antiinflammatory drugs, and insulation. After treatment, the amputated fingers survived completely without major complications, with good recovery.CONCLUSION Supermicroscopy combined with arterio-venolization is a safe and effective approach to treat traumatic digit amputation in young children without venous anastomosis.
