Abstract:
Objective To introduce the clinical experience and investigate venous drainage of distal- ly-based dorsal digital neurocutaneous flap for finger-pulp reconstruction.Methods From Mar.2004 to Oct.2005,18 patients with traumatic finger-pulp defect (＞2cm) were treated by distally based dorsal ho- modigital neurocutaneous flaps.The flap measured 2 cm?2cm～3cm?4cm with the neuro-veno-adipal ped- icle 1cm wide and 2～3cm long.The pivot points were proximal to the PIP joints.The dorsal digital nerve was neurorrhaphied with the proper digital nerve of the recipient site.The dorsal digital vein was ligated at 1cm distal to the pivot point to prevent venous ingress.No venous anastomosis was performed.Results All the flaps survived but had some degrees of venous congestion and swelling,and 8 flaps developed tension blisters. In 13 flaps with follow-up more than 6 months,protective sensation was restored.Conclusion Dorsal digit- al neurocutaneous flap is simple and effective for finger-pulp reconstruction.Ligating the big superficial vein at the distal base to interrupt venous ingress,and allowing the proximal vein open and venous egress,can reduce flap congestion and swelling.
