This case report presents a technique using the superficial circumflex iliac artery perforator (SCIP) flap for immediate reconstruction of the dorsal foot and revascularization of multiple toes. A 28-year-old man suffered a degloving injury on the dorsum of his foot resulting in a 9 × 6cm skin defect, open fracture dislocations, exposure of tendons, and neurovascular injury, which included a 6–7.5 cm segmental defect of the vessels supplying the first, second, and third toes leaving all three toes ischemic. Immediate reconstruction was performed by harvesting a 12.5 × 5cm SCIP flap including both the superficial and deep branches and incorporating the superficial inferior epigastric vein (SIEV). The SCIP deep branch was used to revascularize the third and second toes and the SIEV vein graft used for the first toe. The patient recovered well, no complications were observed at the 2-year follow-up, preserving all three toes and regaining mobility. The use of the SCIP flap as a flow-through flap provides thin skin flap cover, good vessel caliber size match with digital vessels and reduces the need for vein grafts from distant sites improving surgical efficiency. These attributes make the flow-through interposition SCIP flap an excellent choice for reconstructing foot defects and revascularizing toes. We report this case to demonstrate the utility of the SCIP flap in immediate soft tissue cover and digit revascularization.</p>","PeriodicalId":18600,"journal":{"name":"Microsurgery","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/micr.31216","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141752109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ankle area presents little subcutaneous tissue and is often affected by high-energy traumas and bone fractures. Wounds in this region are frequently associated with severe edema that might prevent primary closure. Due to its thinness and tension, the skin overlying both the medial and lateral malleoli is prone to necrosis, which can further lead to large soft tissue defects. Vessels, nerves, and tendons can easily become exposed. The reconstructive approach should aim to provide high-quality tissue that is durable enough to withstand the weight-bearing pressures and the friction from shoes, while remaining sufficiently elastic to conform to the shape of the ankle and to permit the foot movement. In this study, we describe the use of an additional propeller flap to reduce skin tension at the recipient site. A superficial circumflex iliac artery perforator (SCIP) flap was utilized to cover a defect below the medial malleolus. However, after flap inset, achieving a primary closure of the proximal wound without tension was not possible. During the dissection of the posterior tibial artery, perforator vessels were identified and preserved. The larger of these vessels was then used to vascularize a propeller flap, which was then rotated toward the defect to aid a tension-free closure. The postoperative course was uneventful. This case may provide a valuable insight into the challenges often faced during wound closure, even after flap inset. Since the flap itself may increase the width of the dissection area, the present case shows the importance of preserving perforator vessels during the proximal dissection since they can allow the harvest of an additional flap to achieve primary closure and further alleviate tension.</p>","PeriodicalId":18600,"journal":{"name":"Microsurgery","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141731313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we described a protocolized approach for revascularization and reconstruction for functional hand salvage after traumatic amputation from a crushing mechanism using an anterolateral thigh flap (ALT).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>A retrospective review was performed between October 2016 and October 2023 for all patients who underwent single-stage emergent debridement, revascularization, and soft tissue coverage using the ALT after amputation at the level of the wrist or distal forearm secondary to high-energy crush injury. Charts were reviewed for the preoperative Mangled Extremity Salvage Score, intraoperative details including what structures were injured and the reconstructive method performed, and postoperative data such as follow-up duration, outcomes, and complications.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Eleven patients met the inclusion criteria with an average age of 35.5 (21–49) years old. The average size of the skin soft tissue defects was 17.3 × 8 cm (range, length: 13–25 cm, width: 6–13 cm), and all cases had associated injury to the underlying bone, nerves, and blood vessels. The average size of the ALT flap used for reconstruction was 19.2 × 9.8 cm (range, length: 14–27 cm, width: 7–15 cm). All patients had survival of the replanted limb. One patient experienced partial flap necrosis that required secondary debridement and skin graft. Nine patients healed without requiring any additional debridement procedures. Patient follow-up averaged 24.6 (12–38) months. All patients achieved satisfactory functional recovery with Grade II to III of Chen's criteria.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>For patients with traumatic crush amputation to the wrist with surrounding soft tissue injury, thorough debridement, revascularization, and reconstruction of amputated limbs can be performed in a single stage using the ALT.

However, in cases of large defects or damage to the instep area, non-instep flaps such as reverse sural flaps (RSF) or free anterolateral thigh flaps (ALTF) can be employed. Previous studies have primarily focused on heel reconstruction when comparing different flaps, without considering the forefoot. This study aims to verify the clinical outcomes of these flaps and determine the appropriate donor site for weight-bearing areas of the foot including forefoot reconstruction.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>In a retrospective study, 39 patients who had undergone flap reconstruction of weight-bearing area defects in the foot with a follow-up period of ≥1 year were included. The patients were categorized into two groups: Group A (<i>n</i> = 19) using instep flaps, and Group B (<i>n</i> = 20) using non-instep flap including RSFs and ALTFs. Surgical outcomes were assessed based on the success of the flap, the presence of partial necrosis, the number of additional surgeries, and complications related to the donor site. Clinical evaluation included visual analogue scale (VAS) and American Orthopedic Foot and Ankle Society (AOFAS) score, and the occurrence of ulcers.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>All flaps were successful, while partial necrosis occurred in one case in Group B.

The VAS scores during weight-bearing were 2.0 ± 1.1 and 2.2 ± 1.5 for Groups A and B, respectively (<i>p</i> = .716). The AOFAS scores were 52.8 ± 6.8 and 50.2 ± 12.7 for Groups A and B, respectively (<i>p</i> = .435).

Model parameters were derived and averaged from systematic review and institutional experience. VSP cost and surgical time saving was incorporated. We accounted for long-term risks including cancer recurrence and hardware failure/exposure. We calculated cost in US dollars and effectiveness in quality-adjusted-life-years (QALYs). A health care perspective was adopted, discounting costs and effectiveness at 3%/year.

An incremental cost-effectiveness ratio (ICER), or the difference in cost/difference in effectiveness, for VSP was calculated at $68,382/QALY gained. VSP strategy favorability was sensitive to variations of patient age at diagnosis and institutional VSP cost with one-way sensitivity analysis. VSP was less economically favorable for patients &gt;75.5 years of age or for institutional VSP costs &gt;$10,745. In a probabilistic sensitivity analysis, 55% of iterations demonstrated an ICER value below a $100,000/QALY threshold.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions/Relevance</h3>\u0000 \u0000 <p>VSP is economically favorable compared to FHR in patients requiring mandibular reconstruction for advanced oral cancer, but these results are sensitive to the patient's age at diagnosis and the institutional VSP cost. Our results do not suggest if one “should or should not” use VSP, rather, emphasizes the need for patient selection regarding which patients would most benefit from VSP when evaluating quality of life and long-term complications. Further studies are necessary to demonstrate improved long-term risk for hardware failure/exposure in VSP compared to FHR.</p>\u0000 </section>\u0000 </div>","PeriodicalId":18600,"journal":{"name":"Microsurgery","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141469425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
