Limb Salvage Rates and Functional Outcomes Using a Longitudinal Slit Arteriotomy End-to-Side Anastomosis for Limb-Threatening Defects in a High-Risk Patient Population.

Background: Limb salvage techniques using free tissue transfer in patients with chronic wounds caused by longstanding osteomyelitis, diabetes, and peripheral vascular disease are technically challenging. The longitudinal slit arteriotomy end-to-side anastomosis is the authors' preferred technique because it is the least invasive arteriotomy and is especially important for diseased recipient arteries. The authors reviewed highly comorbid patients who underwent free tissue transfer with this technique to understand the success rates, overall outcomes, and long-term limb salvage rates.

Application of Three-Dimensional Printed Vascular Modeling as a Perioperative Guide to Perforator Mapping and Pedicle Dissection during Abdominal Flap Harvest for Breast Reconstruction.

Background:  Advancements in three-dimensional (3D) printing have enabled production of patient-specific guides to aid perforator mapping and pedicle dissection during abdominal flap harvest. We present our early experience using this tool to navigate deep inferior epigastric artery (DIEA) topography and evaluate its impact on operative efficiency and clinical outcomes.

Patients And Methods:  Between January 2013 and December 2018, a total of 50 women underwent computed tomographic angiography (CTA)-guided perforator mapping prior to abdominal flap breast reconstruction, with ( = 9) and without ( = 41) 3D-printed vascular modeling (3DVM).

Bilateral Breast Reconstruction With Profunda Artery Perforator Flaps and Immediate Implant Augmentation.

The smaller volume of the profunda artery perforator (PAP) flap relative to that of abdominal flaps limits the size of breast reconstruction that may be achieved. Immediate implant augmentation of abdominal free flaps has been performed, but immediate implant augmentation of PAP flaps has never been described. A 54-year-old woman with BRCA2 mutation, submuscular implants, and previous abdominoplasty presented for nipple-sparing mastectomies (NSM).

Application of the ORBEYE three-dimensional exoscope for microsurgical procedures.

Background: Advances in digital imaging, screen technology, and optics have led to the development of extracorporeal telescopes, also known as exoscopes, as alternatives to surgical loupes (SLs) and traditional operating microscopes (OMs) for surgical magnification. Theoretical advantages of the exoscope over conventional devices include improved surgeon ergonomics; superior three-dimensional, high-definition optics; and greater ease-of-use. The ORBEYE exoscope, in particular, has demonstrated early efficacy in the surgical arena.

Bridging the Knowledge Gap: An Examination of the Ideal Postoperative Autologous Breast Reconstruction Educational Material with A/B Testing.

Background: Poor health literacy is an epidemic in the United States, associated with higher mortality rates and poor postoperative care. Autologous breast reconstruction is highly complex, and the identification of complications is difficult even for non-plastic surgeon practitioners. The authors sought to explore the problem of health literacy in this context and identify the ideal postoperative patient education materials.

Subtotal calvarial vault reconstruction utilizing a customized polyetheretherketone (PEEK) implant with chimeric microvascular soft tissue coverage in a patient with syndrome of the trephined: A case report.

The syndrome of the trephined is a neurologic phenomenon that manifests as sudden decline in cognition, behavior, and sensorimotor function due to loss of intracranial domain. This scenario typically occurs in the setting of large craniectomy defects, resulting from trauma, infection, and/or oncologic extirpation. Cranioplasty has been shown to reverse these symptoms by normalizing cerebral hemodynamics and metabolism.

Combining Abdominal Flaps and Implants in the Breast Reconstruction Patient: A Systematic and Retrospective Review of Complications and Outcomes.

Background: Implants offer a method for augmenting abdominal flaps in the setting of deficient volume in breast reconstruction. They may be placed immediately at the time of reconstruction or on a delayed basis. The authors seek to compare outcomes from a single surgeon and previously published studies.

Long Term Follow Up of a Vascularized Osteocutaneous Free Flap for Reconstruction in Charcot Neuroarthropathy: A Case Report.

Vascularized osteocutaneous free flaps have seen increasing use in foot and ankle surgery for the repair of bony defects secondary to chronic nonunion, osteomyelitis, and fractures. One example is the Medial Femoral Condyle (MFC) Flap. The utility of the MFC flap for the repair of a bony defect in a diabetic patient, however, has yet to be explored.

Lower Extremity Free Tissue Transfer in the Setting of Thrombophilia: Analysis of Perioperative Anticoagulation Protocols and Predictors of Flap Failure.

Background:  No consensus exists regarding the optimal strategy for perioperative thromboprophylaxis in high-risk microsurgical populations. We present our experience with lower extremity free tissue transfer (FTT) in thrombophilic patients and compare outcomes between non-stratified and risk-stratified anticoagulation protocols.

Methods:  Between January 2013 and December 2017, 57 patients with documented thrombophilia underwent FTT for non-traumatic, lower extremity reconstruction by a single surgeon.

Soft Tissue Coverage of Complex Periprosthetic Defects in Patients With Total Knee Arthroplasty: Analysis of Factors That Influence Reconstructive and Functional Outcomes.

Introduction: Wound breakdown following total knee arthroplasty (TKA) increases the risk of device exposure, infection, and major amputation. Although a variety of options to facilitate coverage of compromised knee joint prostheses exist, the relative safety, efficacy, and functional impact of each has not been determined.

Objective: This study aims to identify those perioperative factors that influence reconstructive and functional outcomes in patients with periprosthetic TKA defects.

Limb Salvage and Functional Outcomes following Free Tissue Transfer for the Treatment of Recalcitrant Diabetic Foot Ulcers.

Background:  Recent evidence documenting high success rates following microvascular diabetic foot reconstruction has led to a paradigm shift in favor of more aggressive limb preservation. The primary aim of this study was to examine reconstructive and functional outcomes in patients who underwent free tissue transfer (FTT) for recalcitrant diabetic foot ulcers (DFUs) at our tertiary referral center for advanced limb salvage.

Methods:  Between June 2013 and June 2016, 29 patients underwent lower extremity FTT for diabetic foot reconstruction by the senior author (K.

Use of an Intra-Arterial Catheter as a Provisional Conduit for Regulated Outflow Management in the Setting of Artery-Only Digital Replantation.

Successful replantation of distal digital segments necessitates the establishment of sufficient outflow to minimize congestion and progressive tissue necrosis. In cases where only arterial anastomosis is feasible, an artificial outlet must be provided to maintain physiological requirements until microvenous circulation regenerates. This can be accomplished using any number of "exsanguination techniques" designed to facilitate egress through ongoing passive blood loss.
