“…In the previous study by Mutaf et al, veins of lateral thoracic flaps were shown to have valves [6]. In our study, surgical and chemical delays caused dilatation of veins, which in turn causes the valves in the flap veins to fail and causes retrograde flow to the flap; this in turn facilitates flow to-and-fro.…”

To increase the survival of proximally pedicled venous island flaps, which are known to be safe only when small, we used surgical and chemical delaying procedures both individually and in combination for 7, 14, and 21 days. Survival was 1% in those flaps designated as controls, in which there was neither surgical nor chemical delay. However, it was 3%, 31%, and 68% at 7, 14, and 21 days, respectively, when surgical delay was used and 16%, 56%, and 86%, at 7, 14, and 21 days, respectively, when chemical delay was used. Survival was 32%, 84%, and 87%, at 7, 14, and 21 days when both chemical and surgical delays were used. We conclude that chemical delay is more effective than surgical delay in increasing survival of proximally pedicled venous island flaps, but the use of combined chemical and surgical delay may reduce the time required for delay.

“…The possible mechanisms to explain how tissue expansion increases the survival of venous flaps were considered as follows 75 : first, dilatation of the venous network after tissue expansion may increase the survival of venous flaps by providing a better drainage of the harmful metabolites; second, tissue expansion may improve the survival of venous flaps by increasing their arterial blood supply due to increase of the number and size of perivenous arterioles. However, further study using expansion is still needed before it is widely accepted in clinical applications.…”

Arterialized venous flaps: A review of the literature

et al. 2010

The arterialized venous flaps are highly regarded in microsurgical and reconstructive surgeries based on advantages of ease of design and harvest without the need to perform deep dissection, no sacrifice of a major artery at the donor site, no limitation of the donor sites, and less donor-site morbidity. Many experimental investigations and clinical applications have been reported. However, their survivals are still inconsistent, and survival mechanisms remain controversial. In this review, we update the existing problems, experimental studies for survival mechanisms, clinical practices, and methods developed to improve their survivals.

“…1 As a result of subsequent contributions, the survival rate of venous flaps has increased to over 90%. [2][3][4][5][6][7][8][9][10][11][12][13] For complex multiple fingertip injuries, including palmar and dorsal longitudinal oblique defects, extending to the proximal end of the distal interphalangeal joint (DIP) crease cannot always be achieved using local homodigital/heterodigital island flaps due to accompanying soft tissue injuries and extension of injury zone to the donor area. 14 Partial skin necrosis after multiple finger replantation surgery, crush injuries, rolling belt injuries, dorsal friction injuries are the most common causes of complex soft tissue defects.…”

Multiple soft tissue finger defects in different shapes and locations are usually difficult to manage. Such defects commonly involve tendons and bones. Palmar soft tissue defects may also lead to vascular compromise. In this retrospective report, we report the results of seven patients with multiple soft tissue finger defects that were covered by syndactylizing arterialized venous flaps. Six of the patients suffered hot-pressing machine and crushing injuries, one patient had a rolling belt injury. All patients presented with soft tissue defects on palmar or dorsal sides involving at least two digits. The palmar forearm was donor site for all patients. At least one afferent artery and two efferent veins were selected for the anastomosis. Lengths of afferent and efferent veins were long enough to perform healthy anastomosis outside the injury zone. The afferent vessels were anastamosed to the digital arteries with the largest possible diameter or to the common digital arteries to maximize flow. The efferent veins were anastamosed to dorsal veins. Separations of the digits were performed after three weeks by longitudinal incisions. The mean follow-up period was 12 months. None of our patients suffered a flap loss. Syndactylizing arterialized venous flaps may be used for composite or single tissue reconstruction for multiple finger defects with satisfactory cosmetic and functional outcomes.
