[Venous drainage of Littler's neurovascular pedicle flap]

The antegrade transosseous injection of the digital veins, followed by dissection enables the authors to analyse the role of various networks in drainage of the pulp. The satellite veins of the digital artery in the finger are probably not involved. The venous return of the pulp is constituted by an anatomical continuity between the superficial palmar network and the common digital veins. A narrow anastomotic channel is demonstrated in the commissure between these two systems.
