The Microvascular Anastomotic Coupler for Venous Anastomosis in Head and Neck Reconstruction: An Institutional Experience.

Background This study aimed to identify outcome predictors with the GEM microvascular coupler system (GEM Coupler) in a series of patients undergoing free flap reconstruction for head and neck defects. Methodology In this retrospective chart review of 218 consecutive microvascular procedures performed on 204 patients at an academic tertiary care center, demographics, comorbidities, surgical data, and outcomes were retrieved. The endpoints for the analysis were microvascular revision surgery and flap survival. Results The study included 142 (70.2%) males and 62 (29.8%) females, with a mean age of 56 years, primarily treated for malignancy (76%). The anterolateral thigh and fibula were the most commonly used flaps (40.4% and 27.1%, respectively). In 21 (9.6%) cases, a double venous anastomosis was performed. There were nine flap failures requiring microvascular revision surgery; the flap was salvaged in four of these cases yielding an overall success rate of 97.7%. Factors associated with total flap loss included a history of a thrombotic or embolic event (p = 0.017), deep circumflex iliac artery flap (p < 0.001), and absence of monitoring skin paddle (p < 0.001). Conclusions Prothrombotic conditions, buried flaps, and flap type are outcome predictors in patients undergoing microvascular reconstruction with GEM Coupler.

No Skin Paddle, No Problem: Burying Deep Inferior Epigastric Artery Flaps in the Immediate Setting is Safe in Select Patient Populations.

In appropriately selected patients, it may be possible to fully bury breast free flaps deep to the mastectomy skin flaps. Because this practice forgoes the incorporation of a monitoring skin paddle for the flap, and thus limits the ability for physical exam, it may be associated with an increased risk of flap loss or other perfusion-related complications, such as fat necrosis. We hypothesized that fully de-epithelialized breast free flaps were not associated with an increased complication rate and reduced the need for future revision surgery. A single-institution retrospective review of 206 deep inferior epigastric artery (DIEP) flaps in 142 patients was performed between June 2016 and September 2021. Flaps were grouped into buried or nonburied categories based on the absence or presence of a monitoring paddle. Patient-reported outcomes were assessed postoperatively using the BREAST-Q breast reconstruction module. Electronic medical record data included demographics, comorbidities, flap characteristics, complications, and revision surgery. The buried flap patients (N = 46) had a lower median body mass index (26.9 vs 30.3, p = 0.04) and a lower rate of hypertension (19.5 vs. 37.5%, p = 0.04) compared with nonburied flap patients (N = 160). Burying flaps was more likely to be adopted in skin-sparing mastectomy or nipple-sparing mastectomy (p = 0.001) and in an immediate or a delayed-immediate fashion (p = 0.009). There was one flap loss in the nonburied group; complication rates were similar. There was a significantly greater revision rate in the nonburied flap patients (92 vs. 70%; p = 0.002). Buried flap patients exhibited a greater satisfaction with breasts (84.5 ± 13.4 vs. 73.9 ± 21.4; p = 0.04) and sexual satisfaction (73.1 ± 22.4 vs. 53.7 ± 29.7; p = 0.01) compared with nonburied flap patients. Burying breast free flaps in appropriately selected patients does not appear to have a higher complication rate when compared with flaps with an externalized monitoring paddle. Furthermore, this modification may be associated with a better immediate aesthetic outcome and improved patient satisfaction, as evidenced by a lower rate of revision surgery and superior BREAST-Q scores among buried DIEP flaps.

The Influence of Inset and Shaping of Abdominal-Based Free Flap Breast Reconstruction on Patient-Reported Aesthetic Outcome Scores-A Systematic Review.

Background: Nowadays, multimodal cancer therapy results in very high survival rates of early-stage breast cancer and microsurgical flap-based breast reconstruction has become safe and reliable, with gradually increasing demand because of its durable and aesthetically pleasing results. This study aimed to explore the impact of different flap shaping and inset techniques on patient-reported outcome measures (PROMs) with regard to the aesthetic result in abdominal flap-based breast reconstruction. Methods: A systematic review was performed screening Pubmed, Cochrane Library and Web of Science for original articles reporting flap inset strategies, concomitantly providing PROMs on the aesthetic result. Results: Of 319 studies identified, six met the inclusion criteria. The studies described different flap rotation options according to the patient's morphology, different inset planes, and avoidance of the monitoring skin paddle, and suggested that a higher flap-to-mastectomy mass ratio was associated with better aesthetic results. In two comparative studies, according to the PROMs (BREAST-Q, Likert scale) and independent observer judgement, both higher patient satisfaction and superior aesthetic results were observed with the newly described techniques. Conclusions: Emphasis on the aesthetic outcome in terms of breast shape and symmetry, providing an individualized approach of flap inset, considering the contralateral breast's shape and volume, results in higher satisfaction scores.

Challenges in Microsurgical Free Tissue Transfer for a 1-Year-Old Child

Challenges faced during complex reconstructions in the pediatric age group are rarely discussed in literature. This study is to share our experience in a 1-year-old patient. The patient had an exposed knee joint following trivial trauma, which was resurfaced with a free latissimus dorsi flap. On the patient’s 5th day in the ward, the flap was discolored and inadequate perfusion was noted. The patient also had loose stools overnight. Before she was re-examined, the dressings were loosened and the patient was kept warm and was started on intravenous fluids. When examined in the operating room, the vascularity of the flap had improved without any intervention. The monitoring skin paddle necrosed while the muscle survived. The patient then underwent skin grafting and had uneventful recovery. The postoperative monitoring in children is critical as they have poor reserves and are prone to complications. We believe pediatric microsurgery should be done in specialized microsurgical centers that also have good intensive care units.

Flow-Through Flap for Salvage of Fibula Osseocutaneous Vascular Variations: A Surgical Approach and Proposed Modification of Its Classification

The osseocutaneous fibula free flap is commonly used in mandibular reconstruction. Clinically important anatomic variants of the donor vessels have been reported. The authors describe a rare variant encountered while raising an osseocutaneous fibula flap. The fibula was supplied by the peroneal vessels and the overlying skin paddle was supplied by musculocutaneous perforators arising from the posterior tibial vessels. By raising 2 separate free flaps and configuring them in microvascular series with the fibula acting as a flow-through flap, the reconstruction was successful. Although the anatomic variant has been described, the authors' approach to it has not. The benefits of this method over other options include preservation of a skin paddle for monitoring and watertight oral closure and a long pedicle to the skin paddle permitting a wide arc of movement. The authors suggest a modification to the existing classification of perforators to the lateral leg skin to guide intraoperative decision making.

Fibular osteoadiposal flap for treatment of tibial adamantinoma: a case report.

We treated a case with left tibial adamantinoma by use of a contralateral fibular osteoadiposal flap. The donor site of conventional fibular osteocutaneous flap must be covered with a skin graft because if we close the donor skin defect directly, compartment syndrome might occur. We were able to close the donor skin defect because this combined type flap included only a small monitoring skin paddle. We present herein the utility of the osteoadiposal flap and show the value of a skin-sparing approach with a minimal aesthetic defect.

A subcutaneous heterotopic limb transplantation model in the mouse for prolonged allograft survival.

A heterotopic position of a limb allograft is advantageous in the fragile mouse model to reduce mortality but is prone to autotomy. The purpose of this study was to describe a new heterotopic limb transplantation model in the mouse for prolonged allograft survival. Eleven lower hindlimbs were transplanted in a heterotopic subcutaneous position in the groin of the recipient animal with the donor skin inset as a skin paddle for monitoring. Seven transplants were syngeneic (Balb/c) and four were allogeneic (C57Bl/6 donor). The overall success rate (acute survival < 7 days) was 73% (8/11) and the mortality rate was 18% (2/11). Five of seven syngeneic transplants survived for 60 days and were harvested for histology. Recipients of successful allogeneic transplants (n = 3) received no immunosuppression and rejected their allografts between 8 and 11 days postoperatively. Mixed lymphocyte culture and flow cytometry demonstrated secondary immune responses by pre-sensitized animals, and histology showed lymphocytic infiltration and necrosis consistent with acute rejection.

Microsurgical Correction of Facial Asymmetry in 60 Consecutive Cases

Restoring soft-tissue contour in patients with facial asymmetry is a difficult problem for plastic surgeons. We report our experience with 57 consecutive patients who underwent 60 microvascular free flaps for the correction of facial asymmetry between July of 1989 and June of 1994. Etiologies of facial asymmetry included hemifacial microsomia, hemifacial atrophy, postradiation sequelae, burns and trauma, and selected congenital anomalies. Thirty-eight patients were reconstructed with a customized parascapular flap incorporating extensions of dorsal thoracic fascia. Other donor sites utilized were as follows: six superficial inferior epigastric flaps, three myocutaneous flaps, seven muscle flaps, and six fasciocutaneous flaps with bone. To correct facial asymmetry, the recipient site was dissected through a limited preauricular incision whenever feasible, and the superficial temporal artery and vein were used as recipient vessels. A monitoring skin paddle was rarely used. There were no flap losses in this series. Six patients experienced a postoperative hematoma, three of which were drained at the bedside. Limited skin slough occurred in three patients. No donor-site complications other than hypertrophic scarring were encountered. Flap revisions were performed in 22 of the 57 patients to maximize aesthetic results. Based on our experience, we feel that the operative approach presented here allows excellent and stable correction of facial asymmetry due to a variety of etiologies. Furthermore, this technique is applicable to other congenital craniofacial deformities such as Treacher-Collins syndrome and orbital-facial clefts.
