  • APPLICATION OF PEDICLE REDUCING TENSION FLAP IN THE DISTALLY-BASED PEDICLE FLAP

    【Abstract】 Objective To explore the effectiveness of reducing tension method on the survival and appearance of distally-based pedicle flap. Methods Between October 2009 and February 2011, 27 cases of defect of extremity skin and soft tissue were repaired with distally-based pedicle flap through reducing tension flap method. There were 19 males and 8 females with an average age of 31.5 years (range, 17-58 years). Defects were caused by traffic accident in 14 cases, by machine in 9 cases, by surgical infection in 3 cases, and by tumor excision in 1 case. The locations were the distal tibia in 7 cases, the ankle-joint in 12 cases, the foot in 5 cases, the palm in 2 cases, and the dorsum of hand in 1 case. The time from injury to hospitalization was 1-19 hours with an average of 10 hours. The size of defect ranged from 5.2 cm × 3.8 cm to 14.0 cm × 5.8 cm. The size of distally-based pedicle flap ranged from 5.5 cm × 4.5 cm to 14.5 c m × 6.5 cm. The donor sites were sutured directly in 6 cases and were repaired with skin grafting in 21 cases. Results All reducing tension flaps survived. Partial necrosis occurred in the distally-based pedicle flap in 3 cases at 7 days after operation, which was cured after dressing change and skin grafting in 1 case, after excision of necrosis skin edge and direct suture in 2 cases. The other flaps survived and wounds achieved primary healing. The incisions at donor sites healed by first intention and skin grafting survived. Twenty-six cases were followed up 6-12 months (mean, 7.5 months). The appearance and texture of the flaps were good. Conclusion Pedicle reducing tension flap could promote the survival and the appearance of distally-based pedicle flap.

  • REPAIR OF SKIN DEFECT ON WRIST AND HAND WITH DISTALLY PEDICELED COMPOSITE VASCULAR NET FLAP OF FOREARM

    Objective To study the blood supply of the distally pediceled composite vascular net flap of forearm and its clinical effect. Methods From February 2000 to December 2003, the distally pediceled composite vascular net flap of forearm was used to repair a series of 26 skin defects with bone or tendon exposure on the hand and wrist.Of 26 patients, there were 17 males and 9 females at ages of 18 to 56 years; 16 received emergency operation and 10 received selective operation. The flap sizes ranged for 10 cm ×5 cm to 18 cm×7 cm. Results Allof the flaps survived. At followup of 3 to 8 months, there was no flap loss, even partial and the outcome was satisfactory in all patients.Twopoint discrimination was 6 to 10 mm. Conclusion Plexus around the cutaneous nerves and the superficial vein are connected with the superficial subdermal plexus and the deep facial plexus by perforators from the underling main arteries, forming a threedimensional vascular network and in a sort of longitudinal axiality, which is the anatomic base of blood supply for the flaps. Blood supply to the flap is provided by the perforators arising from the deeply situated radial or ulnar arteries in the distal pedical. The advantage of this flap is its constant and reliable blood supply without sacrifice of the main artery. The elevation of the flapis simple and rapid, and the flap has a higher survival rate.

  • APPLIED ANATOMY OF SMALL SAPHENOUS VEIN AND ITS DISTALLY-BASED SURALNERVE NUTRIENT

    Objective To investigate the origin of small saphenous vein of distally-based of sural nerve nutrient vessels flap and its clinical application. Methods The origins of nutrient vessels of small saphenousvein and communicating branches of superficial-deep vein were observed on specimens of 30 adult cadaveric low limbs by perfusing red gelatin to dissect the artery. Results The nutrient vessels of small saphenous vein originated from the heel lateral artery, the terminal perforator branches of peroneal artery and intermuscular septum perforating branches of peroneal artery. There were 2 to 5 branches ofsuch distally-based perforating branches whose diameters ranged from 0.6 to 1.0 mm. Those perforating branches included fascia branches, cutaneous branches nerve and vein nutrient branches. Those nutrient vessels formed a longitudinalvessel chain of sural nerve shaft, vessel chain of vein side and vessel networkof deep superficial fascia. The small saphenous vein had 1 to 2 communicating branches of superficial-deep vein whose diameter was 1.7±0.5 mm, 3.4±0.9 cm to the level of cusp of lateral malleolus, and converged into the fibular vein. Conclusion Distally-based sural nerve, small saphenous vein, and nutrient vessles of fascia skin have the same region. The communicating branches of superficial-deep vein is 3 to 4 cm to the level of cusp lateral malleolus. These communicating branches could improve the venousdrainage of the flap.

  • APPLIED ANATOMY OF THE PERFORATING BRANCHES ARTERY AND ITS DISTALLY-BASED FLAP OF SURAL NERVE NUTRIENT VESSELS

    Objective To investigate the distribution of the perforating branches artery of distally-based flap of sural nerve nutrient vessels and its clinical application. Methods The origins and distribution of perforating branchesartery of distally-based flap were observed on specimens of 30 adult cadavericlow limbs by perfusing red gelatin to dissect the artery.Among the 36 cases, there were 21 males, 15 females. Their ages ranged from 6 to 66, 35.2 in average. The defect area was 3.5 cm×2.5 cm to 17.0 cm×11.0 cm. The flap taken ranged from 4 cm×3 cm to 18 cm×12 cm. Results The perforating branches artery of distally-based flap had 2 to 5 branches and originated from the heel lateral artery, the terminal perforating branches of peroneal artery(diameters were 0.6±0.2 mm and 0.8±0.2 mm, 1.0±1.3 cm and 2.8±1.0 cm to the level of cusp lateral malleolus cusp).The intermuscular septum perforating branches of peroneal artery had 0 to 3 branches. Their rate of presence was 96.7%,66.7% and 20.0% respectively(the diameters were 0.9±0.3, 1.0±0.2 and 0.8±0.4 mm, andtheir distances to the level of cusp of lateral malleolus were 5.3±2.1, 6.8±2.8 and 7.0±4.0 cm). Those perforating branches included fascia branches, cutaneous branches, nerve and vein nutrient branches. Those nutrient vessels formed longitudinal vessel chain of sural nerve shaft, vessel chain of vein side and vessel network of deep superficial fascia. The distally-based superficial sural artery island flap was used in 18 cases, all flaps survived. Conclusion Distally-based sural nerve, small saphenous vein, and nutrient vessels of fascia skin have the same origin. Rotation point of flap is 3.0 cm to the cusp of lateral malleolus, when the distally-based flap is pedicled with the terminal branch of peroneal artery.Rotation point of flap is close to the cusp of lateral malleolus, when the distally-based flap is pedicled with the heel lateral artery.
