Improvement of ischemic or congested wound conditions by reconstruction with microsurgical flaps

Intractable chronic wounds share the basic problem of the environment being unfavorable for wound healing and prone to infection, inflammation, and recurrences. Microsurgical flap provides a healthy, well-vascularized normal tissue to compromised intractable environment, and promotes wound healing. In this report, we present the results of microsurgical flaps used for the reconstruction of chronic intractable conditions including chronic ulcer with an ischemic environment and pathologic lesions with a congestive environment.

From 1997 to 2015, 18 patients received microsurgical flaps for chronic intractable conditions. Among them, three patients had radiation ulcers with an ischemic environment and 15 had pathologic lesions with a congested environment, such as vascular malformations. Nine patients were male, and nine were female. The mean age was 31.9 years. All patients were treated using radical excision and reconstruction with microsurgical tissue transfer.

All flaps survived completely. Among three patients with radiation ulcers, two had minor wound disruptions, which were managed conservatively. No further episodes of infections or breakdowns occurred. Among 15 patients who had pathologic lesions, one suffered facial palsy of the forehead. No complications in terms of infection, or recurrences were noted, and resolution of the residual surrounding lesions was observed on follow-ups. No donor related problems occurred in any patients. The mean follow-up period was 10.7 years.

In this report, we present the results of reconstruction of chronic intractable conditions using microsurgical flaps. The reconstruction using microsurgical flaps was clinically successful, with long-term improvement of surrounding tissues and no recurrence.
