  • THREE-DIMENSIONAL VISUALIZATION RECONSTRUCTION OF MEDIAL SURAL ARTERY PERFORATOR FLAP based on Digital technology

    ObjectiveTo explore the feasibility of three-dimensional (3-D) visualization reconstruction of the medial sural artery perforator flap based on digital technology. MethodsA series of Dicom images were obtained from three healthy adult volunteers by dual source CT angiography. Then the Mimics software was used to construct the medial sural artery model and measure the indexes, including the starting position of medial sural artery, external diameters of vascular pedicle, the number of perforators, location perforated deep fascia, and the maximum pedicle length of perforators based on medial sural artery perforator flap. ResultsThe 3-D visualization reconstruction models were successfully finished with Mimics software, which can clearly display the distribution, travel, and perforating point. Thirteen perforators were found in 6 legs, which started at the popliteal artery with a mean external diameter of 2.3 mm (range, 1.9-2.7 mm). Each specimen had 1-3 perforators, which located at the site of 6.2-15.0 cm distal to popliteal crease and 2.5-4.2 cm from posterior midline. The maximum pedicle length of medial sural artery perforator flap was 10.2-13.8 cm (mean, 11.8 cm). ConclusionThe 3-D visualization reconstruction models based on digital technology can provide dynamic visualization of the anatomy of the medial sural artery for individualized design of the medial sural artery perforator flap.

  • MEDIAL SURAL ARTERY PERFORATOR FREE FLAP FOR REPAIR OF DEFECT AFTER TONGUE CANCER ABLATION

    ObjectiveTo investigate the effectiveness of medial sural artery perforator free flap (MSAP) for repairing defect after tongue cancer ablation. MethodsBetween March 2013 and April 2014, the defects after tongue carcinoma resection were repaired with MSAP in 12 patients, including 8 cases of high or medium differentiated squamous cell carcinoma (SCC) and 4 cases of moderately-poor differentiated SCC. There were 7 males and 5 females with a median age of 55 years (range, 45-68 years). The disease duration ranged from 2.0 to 8.5 months (mean, 4.3 months). The tumor located at the tongue edge in 8 cases and at the tongue abdomen in 4 cases (mouth floor infiltration in 1 case). According to TNM stage, 7 cases were rated as T2N0M0, 2 cases as T2N1M0, 2 cases as T3N1M0, and 1 case as T4N1M0. The size of tumor ranged from 3.0 cm×2.0 cm to 4.5 cm×3.0 cm. The size of MSAP varied from 4.0 cm×3.5 cm to 6.5 cm×6.0 cm. ResultsThe time of total operation ranged from 5.5 to 8.3 hours (mean, 6.8 hours), and flap harvesting time ranged from 54 to 85 minutes (mean, 65.6 minutes). The other flaps survived except 1 case of vein crisis. All the patients were followed up 6-18 months (mean, 13.7 months). With time passing, the pronunciation got better, and the skin showed mucosa-like change; the patients were capable of normal language exchange at 6 months after operation. No obvious scar on the leg or limitation of limb motion was observed. ConclusionThe MSAP is reliable for repair of defect after tongue cancer ablation, with the advantages of satisfactory recovery of tongue appearance, language function, and less donor site morbidity.

    ObjectiveTo explore the effectiveness of the free bilobed medial sural artery perforator (BMSAP) flap to repair penetrating wound of the foot. MethodsBetween April 2012 and October 2014, 7 cases of foot penetrating wounds were treated with the BMSAP flap. There were 5 males and 2 females, aged from 21 to 43 years (mean, 31.5 years). The causes of injury included the crush injury (4 cases), blunt puncture (2 cases), and firearm injury (1 case). The wound was located at the left foot in 4 cases and at the right foot in 3 cases. There were longitudinal penetrating injury in 5 cases and transverse penetrating injury in 2 cases. The size of wound ranged from 4 cm×3 cm to 9 cm×7 cm. The interval between injury and admission was 0.5-5.5 hours (mean, 3.2 hours). The free BMSAP flap of 5 cm×4 cm-10 cm×8 cm in size was used to repair the wounds on both sides and to reconstruct the sensation. The donor site was sutured or repaired with skin graft. ResultsAfter operation, 1 case had distal flap necrosis, the flap survived after dressing change; 1 case had wound infection, and delayed healing was obtained after drainage; and the flap survived completely, and primary healing was obtained in the other 5 cases. The skin grafts survived and healing of incision by first intention was observed at donor sites. The patients were followed up from 7 to 24 months (mean, 12.5 months). The flap had soft texture and similar color to normal skin. According to the British Medical Research Council (BMRC) sensory function assessment system, 1 case was rated as S2, 4 cases as S3, and 2 cases as S3+. The American Orthopaedic Foot and Ankle Society (AOFAS) score was 86-97 (mean, 93.6); the results were excellent in 6 cases and good in 1 case. ConclusionThe free BMSAP flap is very suitable to repair penetrating wound of the foot.

  • Application of three-dimensional ultrasound technique in repairing dorsal foot wounds with medial sural artery perforator flaps

    Objective To investigate the accuracy of positioning perforator of medial sural artery with three-dimensional ultrasound technique guided by a wide band linear matrix array volume transducer probe before operation, and the effectiveness of the flap design based on this in repairing the dorsal foot wounds. Methods Between January 2019 and December 2022, 30 patients with skin and soft tissue defects of the dorsal foot were treated. There were 19 males and 11 females, with an average age of 43.9 years (range, 22-63 years). There were 12 cases of traffic accident injury, 15 cases of heavy crushing injury, and 3 cases of machine injury. The time from injury to hospitalization was 1-8 hours (mean, 3.5 hours). The wounds in size of 5 cm×3 cm to 17 cm×5 cm were thorough debrided and covered with vacuum sealing drainage dressing. Then the wounds were repaired with the medial sural artery perforator flaps after no obvious infection observed. To obtain the complete three-dimensional image, the number and position of the medial sural artery perforator branches and the position of the main blood vessels in the muscle were detected and recorded by wide band linear matrix array volume transducer probe before operation. Suitable perforating branches were selected to design the flap and guide the flap incision on this basis. The size of the perforating flap ranged from 6 cm×4 cm to 18 cm×6 cm. The sensitivity and positive predictive value were calculated by comparing preoperative exploration with intraoperative observation of perforating branches, so as to evaluate the positioning accuracy of three-dimensional ultrasound technique. The donor sites were sutured directly in 25 cases and repaired with free skin grafting in 5 cases. Results The 60 perforating branches of medial sural artery were found before operation and 58 during operation in 30 patients. Among them, pre- and intra-operative perforations were consistent with 56. The sensitivity was 93.3% and positive predictive value was 96.6%. The intramuscular position and route of the main blood vessels were basically consistent with the pre- and intra-operative observation. All flaps survived and wounds healed by first intention. All incisions at the donor sites healed by first intention, and all skin grafts survived. All patients were follow up 9-24 months (mean, 14.7 months). The appearance, color, and texture of the flaps were good, and no obvious effect on wearing shoes and walking. At last follow-up, the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind score ranged from 80 to 92, with an average of 87.5. The patient satisfaction was excellent in 29 cases and good in 1 case. Conclusion The three-dimensional ultrasound technique guided by the wide band linear matrix array volume transducer probe can accurately locate the perforating branch of the medial sural artery, and the three-dimensional imaging is more intuitive, which can be used to guide the design and incision of the medial sural artery perforator flap.
