    Three Patients with Full Facial Transplantation
    (New England Journal of Medicine (NEJM/MMS), 2012) Pomahac, Bohdan; Pribaz, Julian; Eriksson, Elof; Bueno, Ericka M.; Diaz-Siso, J. Rodrigo; Rybicki, Frank John; Annino, Donald James; Orgill, Dennis; Caterson, Edward; Caterson, Stephanie; Carty, Matthew; Chun, Yoon; Sampson, Christian; Janis, Jeffrey E.; Alam, Daniel S.; Saavedra, Arturo; Molnar, Joseph A.; Edrich, Thomas; Marty, Francisco; Tullius, Stefan
    Unlike conventional reconstruction, facial transplantation seeks to correct severe deformities in a single operation. We report on three patients who received full-face transplants at our institution in 2011 in operations that aimed for functional restoration by coaptation of all main available motor and sensory nerves. We enumerate the technical challenges and postoperative complications and their management, including single episodes of acute rejection in two patients. At 6 months of follow-up, all facial allografts were surviving, facial appearance and function were improved, and glucocorticoids were successfully withdrawn in all patients.

    Anticoagulants and Statins As Pharmacological Agents in Free Flap Surgery: Current Rationale
    (Open Science Company, LLC, 2015) Pršić, Adnan; Kiwanuka, Elizabeth; Caterson, Stephanie; Caterson, Edward
    Microvascular free flaps are key components of reconstructive surgery, but despite their common use and usual reliability, flap failures still occur. Many pharmacological agents have been utilized to minimize risk of flap failure caused by thrombosis. However, the challenge of most antithrombotic therapy lies in providing patients with optimal antithrombotic prophylaxis without adverse bleeding effects. There is a limited but growing body of evidence suggesting that the vasoprotective and anti-inflammatory actions of statins can be beneficial for free flap survival. By inhibiting mevalonic acid, the downstream effects of statins include reduction of inflammation, reduced thrombogenicity, and improved vasodilation. This review provides a summary of the pathophysiology of thrombus formation and the current evidence of anticoagulation practices with aspirin, heparin, and dextran. In addition, the potential benefits of statins in the perioperative management of free flaps are highlighted.

    Functional MRI to Evaluate “Sense of Self” following Perforator Flap Breast Reconstruction
    (Public Library of Science, 2012) Caterson, Stephanie; Fox, Sharon Elizabeth; Tobias, Adam; Lee, Bernard
    Background: Breast reconstruction is associated with high levels of patient satisfaction. Previous patient satisfaction studies have been subjective. This study utilizes functional magnetic resonance imaging (fMRI) to objectively evaluate “sense of self” following deep inferior epigastric perforator (DIEP) flap breast reconstruction in an attempt to better understand patient perception. Methods: Prospective fMRI analysis was performed on four patients before and after delayed unilateral DIEP flap breast reconstruction, and on four patients after immediate unilateral DIEP flap breast reconstruction. Patients were randomly cued to palpate their natural breast, mastectomy site or breast reconstruction, and external silicone models. Three regions of interest (ROIs) associated with self-recognition were examined using a general linear model, and compared using a fixed effects and random effects ANOVA, respectively. Results: In the delayed reconstruction group, activation of the ROIs was significantly lower at the mastectomy site compared to the natural breast (p<0.01). Ten months following reconstruction, activation of the ROIs in the reconstructed breast was not significantly different from that observed with natural breast palpation. In the immediate reconstruction group, palpation of the reconstructed breast was also similar to the natural breast. This activity was greater than that observed during palpation of external artificial models (p<0.01). Conclusions: Similar activation patterns were observed during palpation of the reconstructed and natural breasts as compared to the non-reconstructed mastectomy site and artificial models. The cognitive process represented by this pattern may be a mechanism by which breast reconstruction improves self-perception, and thus patient satisfaction following mastectomy.

    Bilateral Free Flap Breast Reconstruction Outcomes: Do Abdominal Scars Affect Bilateral Flaps?
    (Wolters Kluwer Health, 2017) Unukovych, Dmytro; Caterson, Edward; Carty, Matthew; Erdmann-Sager, Jessica; Halvorson, Eric; Caterson, Stephanie
    Background: The incidence of bilateral mastectomies is increasing along with the rates of breast reconstructions. A substantial number of patients will present with abdominal scars after Cesarean section, laparoscopy, laparotomy, and so on. The aim of this study was to evaluate the impact of prior abdominal scars on complication rates in abdominal bilateral free flap breast reconstruction. Methods: All consecutive patients with autologous free flap breast reconstruction between 2007 and 2014 were eligible. The relevant demographic and clinical data were prospectively collected into a study-specific database. Complications and reoperations were prospectively registered after postoperative outpatient visits. Results: Overall, 493 patients underwent abdominally based breast reconstruction during the study period: unilateral (n = 250; 50.7%) or bilateral (n = 243; 49.3%). In the bilateral group, the abdominal scar locations were Pfannenstiel (n = 73; 30.1%), midline (n = 16; 6.6%), lower oblique (n = 17; 7.0%), upper oblique (n = 5; 2.1%), and laparoscopic (n = 69; 28.4%). Four (1.7%) flap failures (including 1 converted to a pedicled transverse rectus abdominis flap) were registered, all occurring in patients from the scar group: 3 with Pfannenstiel incision and 1 patient with prior laparoscopy. Pfannenstiel scar was associated with higher risk of hematoma at the recipient site when compared with no scar group (13.7% versus 2.2%; P = 0.006). Partial flap necrosis, infection, and seroma occurred in 14 (5.9%), 8 (3.4%), and 5 (2.1%) patients, respectively, and no differences between the scar groups were identified. Conclusion: Surgical outcomes of bilateral reconstructions in patients with abdominal scars are generally comparable with ones in patients without prior surgery; however, some problems have been identified. These procedures might have some intraoperative considerations and often require increased operative times. Apart from the traditional preoperative computed tomography angiography, intraoperative imaging (e.g., fluorescence angiography) may be advocated in patients with abdominal scars.
