Fusiform Superior Cerebellar Artery Aneurysm Treated With Flow Diversion: A Case Report, Y. Serulle, D. Khatri, J. Fletcher, A. Pappas, A. Heidbreder, D. Langer, R. A. Ortiz

Journal Articles

© 2020 Published by Scientific Scholar on behalf of Surgical Neurology International. Background: Fusiform aneurysms of the distal superior cerebellar artery are rare and challenging to treat. Due to the rarity of these lesions, there is little consensus regarding their management. Treatment options have traditionally included parent artery sacrifice with either an endovascular approach or microsurgical clipping. Given the small diameter of the superior cerebellar artery, flow diversion has not been typically considered as a viable treatment option for these aneurysms. Case Description: A 67-year-old female presented complaining of severe sudden onset headache. Noncontrast head CT demonstrated no intracranial hemorrhage. …

Graduate Medical Education (GME) Resident and Fellow Research Day Posters

Introduction

Enhanced recovery after surgery (ERAS) pathways are associated with better postoperative recovery, however, evidence is lacking in major liver surgery, .This study aimed to evaluate the impact of an ERAS pathway in U.S. veterans undergoing major hepatectomy surgery. We hypothesized that the adoption of an ERAS pathway reduces decreased length of stay (LOS).

Methods

After approval from the Hunter Holmes McGuire VA Medical Center IRB, we compared data from consecutive patients undergoing elective open hepatectomy within an ERAS pathway (January 2019-December 2019) to a previous cohort of patients before introduction of ERAS (July 2016-December 2017). One surgeon performed all …

Treatment Of Persistent Air Leaks Using Endobronchial Valves, Michael Zimmerman, Cole Zingas, Achala Donuru, Scott W. Cowan, Nathaniel Evans Iii, Boyd Hehn

Phase 1

Introduction: Persistent air leaks (PAL) are from bronchopleural fistula resulting from communication between the bronchial tree and pleural space. Endobronchial valves (EBVs) are unidirectional valves placed bronchoscopically preventing airflow to the diseased lung lobe. For non-operable patients with PALs, EBVs offer a potential non-invasive treatment approach to stop air leak and allow lung healing. The purpose of this study is to retrospectively analyze EBV placement to treat non-operable adult patients with PALs.

Methods: We retrospectively analyzed all adult patients that underwent EBV placement for PAL treatment at our institution from January 2016 to June 2019. All patients failed conservative …

Late Complications Of Free Flaps In Head And Neck Microvascular Reconstruction, Swapna Vasudevan, Cory Bovenzi, Md

Phase 1

Introduction: Late free flap complications (LFFC) in head and neck reconstructive surgery occur over 72 hours postoperatively and result in flap loss in 97% of cases. Due to the rarity of LFFC, there is minimal research regarding risk factors for their development. Identifying risk factors for LFFC will result in improved monitoring of patients to prevent flap loss. This study aims to identify risk factors for the development of LFFC.

Methods: The target population of this retrospective cohort study was 116 patients who had undergone an Orbital Exenteration at Thomas Jefferson University Hospital (TJUH) and had LFFC. Data was …

Three-dimensional (3D) hydrogel printing enables production of volumetric architectures containing desired structures using programmed automation processes. Our study reports a unique method of resolution enhancement purely relying on post-printing treatment of hydrogel constructs. By immersing a 3D-printed patterned hydrogel consisting of a hydrophilic polyionic polymer network in a solution of polyions of the opposite net charge, shrinking can rapidly occur resulting in various degrees of reduced dimensions comparing to the original pattern. This phenomenon, caused by complex coacervation and water expulsion, enables us to reduce linear dimensions of printed constructs while maintaining cytocompatible conditions in a cell type-dependent manner. We …

Structural Brain Plasticity In Epilepsy Patients Selected For Laser Interstitial Thermal Therapy: A Study Of Diffusion Tensor Imaging Based Assessment Of Tract Alterations, Umma Fatema, Mahdi Alizadeh

Phase 1

Introduction: The standard of care for drug resistant temporal lobe epilepsy (TLE) involve surgical approaches including anterior temporal lobectomy (ATL) and laser interstitial thermal therapy (LiTT). White matter alterations following ATL are often studied using diffusion tensor imaging (DTI) which utilizes properties of water diffusion to obtain parameters (such as fractional anisotropy or FA) that can be used to detect neural plasticity. Despite being a common procedure, there are very few studies that explore post-surgical neural changes after LiTT. The objective of this study is to evaluate and explore the DTI parameter changes in patients who underwent LiTT.

Methods: DTI …

3d Printing Of Bone Spurs Before Surgical Removal During Total Knee Arthroplasty, John Paul Prodoehl

Phase 1

Project Background: In the United States, total knee arthroplasty (TKA) is the most performed orthopaedic operation. Among the 700,00 patients who received TKA, 21-25% underwent revision due to knee instability. Proper stability of a TKA depends on soft tissue balance for proper alignment in flexion and extension, and improper soft tissue modification is the primary cause of early implant failure. Soft tissue balancing can be complicated by presence of osteophytes on the distal femur or proximal tibia, which may require removal. The three-dimensional structure of osteophytes is often difficult to visualize with imaging, which could cause incomplete removal. Utilizing 3D …

3d Printing Of Bone Spurs Before Surgical Removal, Matthew Chadwick, John Paul Prodoehl, Katelyn Koons, Chris Li, Lauren Schlegel, Jeffrey Henstenburg, Md

Phase 1

Project Background: In the US alone, total knee arthroplasty is the most common performed orthopedic surgery, with over 700,000 cases per year.1 Overall, 21-25% underwent revision due to instability.2 The stability of a TKA depends largely on soft tissue balance for proper alignment in flexion and extension. Soft tissue balancing in TKA depends on posterior femoral condylar osteophytes, which prevent full extension of the knee and increase tension posteriorly. Pre-operative soft tissue visualization is difficult and this leaves an increased chance for implant failure and revision surgery. Having a 3D model of the bone spur before and during the surgery …
