    Evaluation of the pharyngeal airway using computational fluid dynamics in patients with acromegaly.
    Laryngoscope Investig Otolaryngol 2018 Apr 25;3(2):133-138. Epub 2018 Mar 25.
    Department of Anesthesiology and Critical Care Medicine Graduate School of Medical and Dental Sciences, Kagoshima University Kagoshima Japan.
    Objectives: Perioperative airway management may be particularly challenging in patients with acromegaly undergoing trans-sphenoidal pituitary surgery (TSS). Management for airway obstruction is required prior to pituitary surgery to minimize perioperative hypoxia. The purpose of this retrospective study was to evaluate airway obstruction by simulation of computational fluid dynamics (CFD) using computed tomography (CT) images in patients who had undergone TSS.

    Simulation as a preoperative planning approach in advanced heart failure patients. A retrospective clinical analysis.
    Biomed Eng Online 2018 May 2;17(1):52. Epub 2018 May 2.
    National Research Council, Institute of Clinical Physiology, Rome, Italy.
    Background: Modelling and simulation may become clinically applicable tools for detailed evaluation of the cardiovascular system and clinical decision-making to guide therapeutic intervention. Models based on pressure-volume relationship and zero-dimensional representation of the cardiovascular system may be a suitable choice given their simplicity and versatility. This approach has great potential for application in heart failure where the impact of left ventricular assist devices has played a significant role as a bridge to transplant and more recently as a long-term solution for non eligible candidates.

    A data-driven patient blood management strategy in liver transplantation.
    Vox Sang 2018 May 1. Epub 2018 May 1.
    Division of Transplantation, Department of Surgery, University of Washington, Seattle, WA, USA.
    Background And Objectives: Blood utilization during liver transplant has decreased, but remains highly variable due to many complex surgical and physiologic factors. Previous models attempted to predict utilization using preoperative variables to stratify cases into two usage groups, usually using entire blood units for measurement. We sought to develop a practical predictive model using specific transfusion volumes (in ml) to develop a data-driven patient blood management strategy. Read More

    Prevention and management of complications following tracheal resections-lessons learned at the Massachusetts General Hospital.
    Ann Cardiothorac Surg 2018 Mar;7(2):237-243
    Division of Thoracic Surgery, Massachusetts General Hospital, Boston, MA, USA.
    Tracheal surgery has developed and evolved over the last 50 years, becoming an integral part of the clinical practice of modern thoracic surgeons. Today, surgeons can safely and effectively operate on most patients suffering from post-intubation tracheal stenosis, tracheal tumors and other pathologies that result in an abnormal shape and function of the central airways. The Massachusetts General Hospital (MGH) in Boston witnessed first-hand the birth and growth of tracheal surgery under Dr. Read More

    Transaxillary decompression of thoracic outlet syndrome patients presenting with cervical ribs.
    J Vasc Surg 2018 Apr 25. Epub 2018 Apr 25.
    Division of Vascular Surgery, Gonda (Goldschmied) Vascular Center, David Geffen School of Medicine at UCLA, Los Angeles, Calif.
    Objective: The transaxillary approach to thoracic outlet decompression in the presence of cervical ribs offers the advantage of less manipulation of the brachial plexus and associated nerves. This may result in reduced incidence of perioperative complications, such as nerve injuries. Our objective was to report contemporary data for a series of patients with thoracic outlet syndrome (TOS) and cervical ribs managed through a transaxillary approach. Read More

    A Comparative Report on Intracranial Tumor-to-Tumor Metastasis and Collision Tumors.
    World Neurosurg 2018 Apr 26. Epub 2018 Apr 26.
    Department of Neurosurgery, Brown University, Providence, Rhode Island, USA; Normal Prince Neurosciences Institute, Brown University, Providence, Rhode Island, USA; Warren Alpert Medical School of Brown University, Brown University, Providence, Rhode Island, USA. Electronic address:
    Background: The incidence of 2 distinct tumor types occupying the same anatomic location is rarely observed and may be accounted for by 2 separate mechanisms: tumor-to-tumor metastasis and collision tumors, where 2 adjacent tumors invade one another. These rare phenomena arise from distinct mechanisms, which may affect their preoperative recognition, surgical approach, and postoperative care. We review 2 cases, highlighting their identification and perioperative management. Read More

    Obstructive Sleep Apnea and the Impact on Surgical Outcomes in Gynecology.
    Obstet Gynecol Surv 2018 Apr;73(4):242-250
    Associate Professor, Division of Gynecologic Oncology, Department of Obstetrics and Gynecology, University of Wisconsin School of Medicine and Public Health, Madison, WI.
    Importance: Obstructive sleep apnea syndrome (OSAS) is a common medical condition in the United States and affects gynecologic surgical outcomes.

    Objective: The aim of this review was to improve perioperative diagnosis and management of OSAS in patients presenting for gynecologic surgery and ultimately improve perioperative outcomes. The role of preoperative evaluation and screening is also addressed. Read More

    The Role of 3D Reconstruction True-Volume Analysis in Osteochondral Lesions of the Talus: A Case Series.
    Foot Ankle Int 2018 Apr 1:1071100718771834. Epub 2018 Apr 1.
    1 Department of Orthopaedic Surgery, Penn State Hershey Bone and Joint Institute, Penn State Milton S. Hershey Medical Center, Hershey, PA, USA.
    Background: Evaluation and management of osteochondral lesions of the talus (OLTs) often warrant advanced imaging studies, especially in revision or cases with cystic defects. It is possible that orthopedic surgeons may overestimate the size and misinterpret the morphology of OLT from conventional computed tomography (CT), thereby influencing treatment strategies. The purpose of this study was to determine the utility of a novel means to estimate the true-volume of OLTs using 3D reconstructed images and volume analysis. Read More
