The Effect of Venous Augmentation on Complication Rates in Deep Inferior Epigastric Perforator Breast Reconstruction.

Background: With the rising popularity of the deep inferior epigastric perforator (DIEP) flap in breast reconstruction, use of the superficial inferior epigastric vein (SIEV) to augment venous outflow has been proposed as a strategy to prevent venous congestion, a complication positively associated with flap volume. This study evaluated the impact of routine SIEV venous augmentation on the risk of vascular complications or operative fat necrosis in the context of flap size and operating time.

Methods: A retrospective cohort study compared complication rates of patients with SIEV-augmented DIEP flaps to controls over a 3-year period.

Thigh Perforator Exchange: Intraflap Perforator Augmentation of Anterolateral Thigh Free Flaps.

Peripheral perfusion in large anterolateral thigh flaps may be inadequate if perforator zones are not properly planned during flap design and harvest, and variations in vascular anatomy can contribute to operative difficulty and morbidity. Intraflap anastomosis of extrinsic perforators may allow for augmentation of perfusion while avoiding significant intramuscular dissection. Adaptation of the perforator exchange technique, previously described in autologous breast reconstruction, optimizes vascular flow in anterolateral thigh flaps.

The Vertical Profunda Artery Perforator Flap for Perineal Reconstruction.

Background: Colorectal cancer is a significant cause of cancer-related death in the United States with abdominoperineal resection (APR) remaining a necessary procedure for many patients. The resultant defects of this radical operation are complex and characterized by significant tissue voids. Pedicled vertical profunda artery perforator flaps (vPAP) can be used to obliterate these defects in patients receiving minimally invasive APR or when the abdominal donor site is unavailable.

Cutaneous Wound Healing and the Effects of Cannabidiol.

Cutaneous wounds, both acute and chronic, begin with loss of the integrity, and thus barrier function, of the skin. Surgery and trauma produce acute wounds. There are 22 million surgical procedures per year in the United States alone, based on data from the American College of Surgeons, resulting in a prevalence of 6.

Use of Flow-through Free Flaps in Head and Neck Reconstruction.

Background: Reconstructive obstacles in composite head and neck defects are compounded in reoperated, traumatized, irradiated, and vessel-depleted surgical fields. In cases that require multiple free flaps, recipient vessel accessibility and inset logistics become challenging. Strategic flow-through flap configurations mitigate these issues by supplying arterial inflow and venous outflow to a second flap in a contiguous fashion.

Autologous Breast Reconstruction with Bilateral Stacked Free Flaps in Massive Weight Loss Patients.

Patients with a history of massive weight loss who are undergoing autologous breast reconstruction after mastectomy represent a unique surgical challenge. Although these patients often have an abundance of excess skin, it may be difficult to acquire sufficient tissue volume for adequate reconstruction of bilateral breasts using single flap techniques due to the paucity of subcutaneous fat. Stacked flap techniques have emerged as an effective method in thinner patients with suboptimal fat distribution who desire autologous breast reconstruction.

Autologous Mandible Reconstruction in a Hypercoagulable Patient following Multiple Failed Free Flaps.

Coagulopathies affect 3% of free flap patients and are among the leading causes of free flap failure. This report describes the case of a head and neck cancer patient that experienced two remote free flap failures before successful autologous mandibular reconstruction. Following identification of an unrecognized thrombophilic state, a focused anticoagulation strategy was executed, including an intraoperative heparin drip, stringent postoperative maintenance of Factor Xa levels between 0.

Preoperative Computed Tomography Angiography for ALT Flaps Optimizes Design and Reduces Operative Time.

Background:  Computed tomography angiography (CTA) has been widely used for perforator mapping in abdominal-based reconstruction, but it is less widespread in the anterolateral thigh (ALT) flap. However, CTA may be quite useful for ALT planning, as this flap has demonstrated substantial variability in intrapatient bilateral vascular anatomy. This study investigated whether standard use of preoperative CTA resulted in selection of the donor extremity with preferential perforator anatomy, and whether this affected operative time and postoperative outcomes.

Frontal Cranioplasty with Vascularized Split-iliac Crest Bone Flap.

Defects of the frontal bone require thoughtful consideration of reconstructive material to satisfy the aesthetic and functional demands of the region, as well as the anatomic adjacency to the frontal sinus. Some cases may be further complicated by a suboptimal operative field due to prior radiation, reconstructive procedures, or infection. Vascularized bone offers an ideal option to successfully reconstruct bony defects in harsh wound beds.

The Impact of Indocyanine Green Angiography on Fat Necrosis in Deep Inferior Epigastric Perforator Flap Breast Reconstruction.

Background: The deep inferior epigastric perforator flap (DIEP) is a widely known reliable option for autologous breast reconstruction. One common complication of DIEP procedures is fat necrosis. Consequences of fat necrosis include wound healing complications, pain, infection, and the psychological distress of possible cancerous recurrence.

Simplifying Bony Midface Reconstruction with Patient-specific Titanium Plates.

Virtual surgical planning and patient-specific osteosynthesis plates provide reconstructive surgeons with the ability to proceed with facial reconstruction of expanding complexity. Moreover, these advances have been shown to reduce the energy, effort, and operating time while helping guide the surgeon toward anatomically correct results. The currently available literature regarding custom-milled plates pertains mostly to reconstructive surgery of the mandible.

Stratification of Surgical Risk in DIEP Breast Reconstruction Based on Classification of Obesity.

Background:  From both a medical and surgical perspective, obese breast cancer patients are considered to possess higher risk when undergoing autologous breast reconstruction relative to nonobese patients. However, few studies have evaluated the continuum of risk across the full range of obesity. This study sought to compare surgical risk between the three World Health Organization (WHO) classes of obesity in patients undergoing deep inferior epigastric perforator (DIEP) flap breast reconstruction.

Staged Biliary Reconstruction After Orthotopic Liver Transplantation: A Practical Surgical Strategy for High-Acuity Adult Recipients.

Unlabelled: Biliary complications (BC) following orthotopic liver transplantation (OLT) is strongly associated with inferior patient outcomes and increased healthcare cost. BC in high-acuity patients can be lethal. While the utility of staged biliary reconstruction after liver transplantation (SBRALT) has been reported in adult and pediatric OLT, biliary outcome data are scarce.

Comparing mental health disorders among sex trafficked children and three groups of youth at high-risk for trafficking: A dual retrospective cohort and scoping review.

Background: Individuals at high-risk for trafficking are often subject to preexisting complex trauma that only intensifies during the trafficking experience. This greatly increases their risk of mental illness, although the actual prevalence of mental health disorders in children who are sex trafficked remains unclear.

Objective: To examine the prevalence of mental health diagnoses among a sample of youth identified as being sex trafficked, and to discuss these rates in relation to other high-risk groups reported in the literature.

Tumor-derived cytokines impair myogenesis and alter the skeletal muscle immune microenvironment.

Muscle wasting is a decline in skeletal muscle mass and function that is associated with aging, obesity, and a spectrum of pathologies including cancer. Cancer-associated wasting not only reduces quality of life, but also directly impacts cancer mortality, chemotherapeutic efficacy, and surgical outcomes. There is an incomplete understanding of the role of tumor-derived factors in muscle wasting and sparse knowledge of how these factors impact in vivo muscle regeneration.
