Objective
Replacement of full thickness soft tissue defects in the lower leg and ankle, appropriate to the defect and following the course of blood vessels feeding the skin of a distally hinged fasciocutaneous flap most reliably based on the individual anatomy of distal perforators of the posterior tibial artery.Indications
Full thickness soft tissue defects, up to 12 cm in length and up to 8 cm in width. Sufficient vascularization of the foot required, in osteomyelitis, and when joints, fractures, implants and tendons are exposed and when a split skin graft, a local flap, a suralis perforator flap or a free flap is not indicated.Contraindications
For patients, in whom a 1–2 h operation is not possible; necessity of angioplasty; decollement or scars around the distal perforators of the posterior tibial artery; local infection or necrosis of soft tissues and/or bone, which cannot be totally excised.Surgical technique
Radical debridement; flap dissection without tourniquet; microdissection; design of the flap on the skin: pivot point ~?10 cm (6–14 cm) proximal of the tip of the medial malleolus; base ~?5 cm in width, between the course of the saphenous nerve and of the great saphenous vein and the Achilles tendon; adipofascial pedicle up to 15 cm in length sited over the septum between soleus and flexor digitorum muscles, following the course of the saphenous nerve, with a central skin stripe, which expands into a proximal skin island; skin island is outlined similar to the defect, but larger by 1 to 2 cm, surrounded by an adipofascial border: adjustment of the planning as well as of the elevation of these flaps according to the individual position and the caliber of perforators requires in each case the search for a perforator at the estimated pivot point. Delay of transposition, if the division of more than one perforator proximal to the pivot point obviously diminishes circulation. No “tunnelling “of the pedicle; defects of skin due to the elevation of the flap are replaced by split and meshed skin grafts or temporary by “artificial skin”. A gap in the bandage over the skin island allows for observation.Postoperative management
Protocol of controls of vascularization: color and time for revascularization; antibiotic treatment according to bacteriological testing. In case of edema or discoloration of the flap: immediate removal of sutures, administration of leeches, operative revision. Split skin graft 1 week after flap transposition, if the skin had been temporary substituted.Results
Retrospective uncontrolled study with over 70 saphenous perforator flaps from 1995–2011. Full soft tissue defects 62 times with osteomyelitis, 3 times with endoprothesis, 3 times with fractures, 2 times with exposed tendons. From 1995–2006, 44/50 (88?%) flaps healed completely or at least to 3/4 without the necessity of further flaps; from 2007–2011, 13/20 (65?%) flaps healed completely and 6/20 (30?%) flaps healed at least to 3/4 without the necessity of further flaps, loss of one flap (5?%). 相似文献2.

Methods Wrap-around flap transfer was used to reconstruct degloved thumbs in 8 cases,which left soft tissue defects of the big toe ranging from 2.5 cm×4.9 cm to 3.5 cm×6.8 cm. The reverse fascial island flap pedicled by the dorsalis pedis artery was designed at the anterior ankle with the plantar perforator as pivot point and the surface projection of dorsal pedis artery as axis. The fascia around the dorsalis pedis artery was included in the flap. Proximal branches of the dorsalis pedis artery were ligated and the flap was lifted and rotated to cover the big toe defect. Full-thickness skin was grafted on top of the fascial flap. Results All flaps and skin grafts survived. Blood supply of the foot was not compromised. Postoperative follow-up ranged from 3 to 18 months. The length of the donor big toes was preserved. The contour of toes repaired by flaps was good. There was no contracture of skin grafts. Protective sensation was restored. Walking and motion of the toes was normal. Conclusion Dorsalis pedis artery reversed fascial island flap is easy to harvest and rotate. It has rich blood supply. Transfer of this flap can preserve the length and contour of the big toe and therefore is an ideal method to cover donor site defects left by wrap-around flap harvest. 相似文献

Defects involving the distal leg and foot are frequently encountered following various aetiological factors. Paucity of local tissue causes surgeons to resort to the retrograde peninsular flap, the cross leg flap or the free flap. With specific knowledge of perforators, the fasciocutaneous flap from the calf area can be transferred to the defect in a single stage based on skeletonised distal perforators. The surgical anatomy, flap planning and procedure have been detailed. Nineteen patients were treated during the period 1995 to 2005. The perforators were identified preoperatively by audio Doppler. The flaps were marked and dissected proximal to the defect skeletonising the distal perforators under loupe magnification and transferred to the defect in a single stage. The donor site was skin grafted. Out of 19 cases, 16 flaps healed uneventfully, one flap necrosed completely and in two cases there was marginal necrosis. The cases were followed up for 2-10 years with an average of 6 years. With detailed knowledge of perforators one can safely reconstruct distal moderate-size defects of the lower limb in a single stage, thus having the benefits of free tissue transfer without resorting to microsurgery. This technique has proved to be an advancement in the reconstructive repertoire allowing flaps of non conventional dimensions to be perfused by skeletonised perforators. 相似文献

Distally based radial forearm flap with preservation of the radial artery: anatomic,experimental, and clinical studies 总被引:1,自引:0,他引:1
In this article we report on the anatomical, experimental, and clinical investigations of the distally adipofascial pedicled radial forearm flap based on the small perforators around the radial styloid process. There are about 10 small perforators (0.3-0.5 mm in diameter) from the distal radial artery around the radial styloid process. The longitudinal chain-linked vascular plexuses (suprafascial, paraneural, and perivenous) formed by the forearm ascending and descending branches of septofasciocutaneous perforators meet and cross over with the transverse carpal vascular plexuses around the radial styloid region. Based on these directional-oriented plexuses, distally based adipofascial pedicled radial forearm fasciocutaneous and adipofascial flaps were designed and successfully applied in 34 clinical cases. The pivot point was located at 1-2 cm above the radial styloid. The skin island plus adipofascial pedicle measured between 9-18 cm in length, with the adipofascial pedicle 3-4 cm in width. The length-to-width ratio is 3-5:1. The venous drainage of this distally based flap was investigated anatomically and experimentally. The cephalic vein has no positive role for venous drainage in distally based flaps. The difference between distally based flaps and reverse-flow flaps, clinical selection of fasciocutaneous and adipofascial flaps, advantages and disadvantages, and technical tips for operative success are discussed. 相似文献

BACKGROUND: This curvilinear- and trapezoidal-shaped flap essentially consists of two conjoined V-Y flaps end to side. The vascular supply is supported by the subcutaneous vascular network and is dependent on fascial and muscular perforators. A review of 15 clinical cases was performed to assess the reliability and versatility of the flap. METHODS: Twelve keystone flaps were performed following excision of skin tumours or post-traumatic defects in various locations, from the head and neck region, the trunk and the limbs. RESULTS: No flap necrosis, even partial, was observed regardless of the site and the type of keystone used. Patients were almost pain free in the postoperative course. The aesthetic results are quite satisfactory, as the flap is aligned locally without evidence of the 'pincushioning' appearance sometimes seen around island reconstructions. DISCUSSION: Elevation of the flap seems to evenly distribute the tensional forces without undermining. The flap is particularly useful in the repair of defects following skin cancer removal. Bulk is not a problem and good skin cover is achieved. CONCLUSION: The presence of perforators and subcutaneous network distributed throughout the body create an environment which makes this flap universally applicable and extremely reliable. 相似文献

The reverse posterior interosseous flap: A solution for flap necrosis based on a review of 87 cases.
M Akinci S Ay S Kamiloglu O Er?etin 《Journal of plastic, reconstructive & aesthetic surgery》2006,59(2):148-152
PURPOSE: The relationship of the flap necrosis to the placement of the flaps on the forearm was outlined and a solution in avoiding flap necrosis is discussed. METHODS: The relationship of the flap necrosis to the placement of the flaps on the forearm was investigated in 87 consecutive posterior interosseous island flaps used for the reconstruction of the hand and wrist. Fifty-eight flaps were taken from the middle and proximal thirds of the forearm, the distal edges being within the middle third of the forearm in 24 and the distal edges being within the distal third of the forearm in 34. Twenty-nine flaps were harvested within the boundaries of the distal two-thirds of the forearm, the distal edge being proximal to the distal third of the forearm in 23 and the distal edge being distal to the third of the forearm in six. The Length of the flaps varied from 6.5 cm to 12 cm. The pedicle length measure 4-13 cm. The number of perforators for each flap was recorded also. RESULTS: Flaps survived complete in 78 (89.6%) patients. Six patients had superficial necrosis of the distal part of the flap (6.8%). Three flaps were totally lost and alternative coverage was used (3.8%). The flaps that ended up with partial necrosis appeared to be in related to the site it was taken from. One flap with total necrosis and one with partial ncrosis were taken within the boundaries of the proximal third of the forearm while the distal edge was proximal to the level of distal third. One flap with total necrosis and one with partial necrosis were taken from the proximal third of the forearm while their distal edge were at the limits of the distal third of the forearm. The remaining flap ending up with total necrosis was taken from the distal third of the forearm with a short pedicle. CONCLUSIONS: For the reverse posterior interosseous flap to be reliable the flap should include the septocutaneous perforators in the distal third of the forearm. To cover distant defects reliably by a flap with a long pedicle, the flap should extend up to the distal third of the forearm to include a piece of skin with numerous perforators. 相似文献
