While the profunda artery perforator (PAP) flap and gracilis-based flaps are most commonly utilized in this scenario, certain anatomic variations may favor alternative flap selection. One such option is the medial circumflex femoral artery perforator flap (MCFLAP). This report describes a case of a 60-year-old patient with a history of abdominoplasty and left breast cancer who underwent skin sparing mastectomy, adjuvant radiation, and ultimately, unilateral autologous breast reconstruction using stacked MCFLAPs. While PAP flaps were initially considered, preoperative CT imaging revealed large septocutaneous perforators originating from the MCFA system, bilaterally. The flaps were designed and harvested on these perforators and weighed 335 g on the right and 355 g on the left. The internal mammary system was accessed at the level of the third rib, and the anterograde and retrograde artery and vein were used as recipient vessels. The patient did not experience any complications postoperatively. A revisionary and symmetrizing procedure was performed several months later, and at 18 months, the patient had completely healed and reported satisfaction with the reconstruction. In addition to a detailed case description, the purpose of this report is to provide a review of the available literature on the MCFLAP including the anatomy, indications, and potential benefits and downfalls of this rare perforator flap. While the PAP flap is our preferred second-line option for autologous breast reconstruction, it is important to be aware that in some instances the more suitable perforators may be arising from the MCFA system.

The most frequently utilized combinations were the thoracodorsal artery perforator (TDAp) and anterolateral thigh (ALT) flap (11 cases).

However, rates of arterial or venous thrombosis, and subsequent failure, remain high in burn and trauma reconstruction when compared to autologous breast reconstruction and other elective flaps. To address the higher failure rate, we use a novel vascular approach. We create a pedicular arteriovenous fistula (PAVF), allowing the flow to be enhanced across the microvascular anastomoses.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We performed a retrospective review of 13 consecutive patients with 14 free flaps who underwent PAVF creation by the first author, AO. All patients who required free tissue transfer for trauma and burn reconstruction were indicated for PAVF during this study period. The flaps in this study included ALT, fibula, parascapular, and partial latissimus. The perforator and pedicle for the flaps were dissected in the usual manner. Distal to the takeoff of the perforator to the flap, the pedicular artery and the larger of the accompanying veins were anastomosed to create the PAVF.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Patients were followed for a mean of 171 days Thrombosis was a rare complication in the group with one venous thrombosis (<i>n</i> = 1, 7.14%) and no arterial thrombosis. The most common complication was return to the operating room <i>n</i> = 4 (28.57%), two of which secondary to hematomas (14.29%), one wound dehiscence and one venous thrombosis. This latter patient eventually had partial flap loss.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Discussion</h3>\u0000 \u0000 <p>We did not observe flap ischemia due to vascular steal, nor any venous congestion from pressurizing the venous outflow. As opposed to anticoagulation, flow enhancement aims to decrease the risk of thrombosis by reducing stasis. While further data is needed to compare the outcomes of venous enhanced flaps when compared to flaps treated prophylactically with anticoagulation, our initial data suggests that PAVF is a safe procedure and does not result in vascular steal or flap congestion.</p>\u0000 </section>\u0000 </div>","PeriodicalId":18600,"journal":{"name":"Microsurgery","volume":"44 8","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142569080","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}
