Abstract

Purpose: Soft tissue defects of the distal lower extremity are commonly accompanied by a fracture of the lower extremities. Theses defects are caused by the injury itself or by complications associated with surgical treatment of the fracture, which poses challenging problem. The reverse superficial sural artery flap (RSSAF) is a popular option for these difficult wounds. This paper reviews these cases and reports the clinical results. Materials and Methods: Between August 2003 and April 2018, patients who were treated with RSSAF for soft tissue defects of the lower third of the leg and ankle related to a fracture were reviewed. A total of 16 patients were involved and the mean follow-up period was 18 months. Eight cases (50.0%) of the defects were due to an open fracture, whereas the other eight cases (50.0%) were postoperative complication after closed fracture. The largest flap measured 10×15 cm2 and the mean size of the donor sites was 51.9 cm2. The flap survival and postoperative complications were evaluated. Results: All flaps survived without complete necrosis or failure. One case with partial necrosis of the flap was encountered, but the wound healed after debridement and repair. One case had a hematoma with a pseudoaneurysmal rupture of the distal tibial artery. On the other hand, the flap was intact and the wound healed after arterial ligation and flap advancement. A debulking operation was performed on three cases for cosmetic reasons and implant removal through the flap was performed in three cases. No flap necrosis was encountered after these additional operations. Conclusion: RSSAF is a relatively simple and safe procedure for reconstructing soft tissue defects following a fracture of the lower extremity that does not require microsurgical anastomosis. This can be a useful treatment option for soft tissue defects on the distal leg, ankle, and foot.

목적: 하지, 특히 정강이 앞 부분이나 발, 발목에서의 연부조직 결손은 피복에 어려움이 있다. 저자들은 하지의 개방성 골절 또는 폐쇄적 골절 후 수상부위에 발생한 다양한 연부조직 결손에 대하여 역행성 표재 비복동맥 피판술을 사용하여 피복을 시행한 예들을 수집, 분석하여 그 임상적 결과를 보고하고자 한다. 대상 및 방법: 2003년 8월부터 2018년 4월까지 하지의 골절 후 수상 부위에 발생한 연부조직 결손에 대하여 역행성 비복동맥 피판술을 시행받은 환자를 대상으로 하였다. 수술 후 최소 6개월 추시가 가능했던 16명의 환자를 대상으로 하였으며, 평균 추시기간은 18개월이었다. 8예는 개방성, 다른 8예는 폐쇄적 골절 후 발생한 합병증으로 연부조직 결손이 발생했다. 피판의 평균크기는 51.9 cm2였으며, 가장 큰 피판의 크기는 10×15 cm2였다. 결과 분석을 위해 수술 후 피판의 생존 여부와 추가 술식, 합병증 등을 조사하였다. 결과: 최종 추시 시 이식 피판은 모두 생존하였으며, 공여부에 별다른 합병증도 발생하지 않았다. 수술 후 단기 추시 당시 1예에서 경계부의 부분 괴사 소견이 발견되었으나 변연절제술과 1차 봉합을 통해 회복되었다. 다른 1예에서는 혈종이 발생하여 추가로 혈종제거술을 시행하였으며, 추시기간 내 피판은 성공적으로 생존하였다. 이식부의 미용적 목적으로 피판 축소수술이 3예에서 시행되었고, 피판부를 절개하고 접근하여 내고정물을 제거하거나 추가적 내고정술을 시행한 건이 3예였었다. 결론: 역행성 표재 비복동맥 피판술은 하지 골절과 동반된 연부조직 결손의 치료에 있어 적극적 적용을 고려할 만한 유용한 술기의 하나가 될 수 있을 것으로 생각된다.
