Use of Heparin Cream for Venous Congestion in the Extended Reverse Metacarpal Artery Flap: A Case Report.

Finger dorsum defects are a challenging situation. Many reconstruction methods are used in these defects. Extended reverse dorsal metacarpal artery (RDMA) flap is used in dorsal finger reconstruction. Venous congestion in this flap is most important cause of flap failure. In this case, we presented a case in which we used heparin cream due to development of venous congestion in our patient who underwent an extended RDMA flap. A 24-year-old female patient presented to the emergency department with a defect of dorsal of left-hand fourth finger. Defect was covered with an extended RDMA flap. On postoperative first day, venous congestion was observed, and heparin cream was applied three times a day on flap. The signs of venous congestion were regressed. Tissue healed as a result of superficial epidermolysis and skin grafting. No functional limitation was observed in sixth-month postoperative control. Venous congestion is the most important cause of flap failure of extended RDMA flaps. Generally, subcutaneous heparin administration and leech therapy are used. In our case, heparin was applied as a cream instead of subcutaneously, and flap healing was observed as a result of superficial epidermolysis. Heparin cream application can also be used as a treatment option in flaps with venous congestion.
