Background: Splenic embolization for traumatic vascular abnormalities in stable patients is a common practice. We hypothesize that modern contrast-enhanced computed tomography (CT) over diagnoses posttraumatic splenic vascular lesions, such as intraparenchymal pseudoaneurysms (PSA) that may not require embolization.
Methods: We reviewed the experience at our high-volume center with endovascular management of blunt splenic injuries from January 2016 to December 2021.
Introduction: In an ongoing effort to improve survival and reduce blood loss from hemorrhagic injuries on the battlefield, new hemostatic dressings continue to be developed. This study aimed to determine the efficacy of a novel silicon dioxide-based hemostatic matrix (HM) and compare it with the current military standard Quikclot Combat Gauze (QCG) utilizing a lethal femoral artery injury model.
Materials And Methods: The femoral arteries of 20 anesthetized swine were isolated, and an arteriotomy was performed.
The US-Mexico border is the busiest land crossing in the world and faces continuously increasing numbers of undocumented border crossers. Significant barriers to crossing are present in many regions of the border, including walls, bridges, rivers, canals, and the desert, each with unique features that can cause traumatic injury. The number of patients injured attempting to cross the border is also increasing, but significant knowledge gaps regarding these injuries and their impacts remain.

Trauma has a known association with hypercoagulability. Trauma patients with concurrent COVID-19 infection potentially have an even greater risk of thrombotic events.

There is currently limited data on the pathogens complicating a trauma patient's ECMO course, making empiric antibiotic decisions difficult. This study aims to characterize the types of infection among patients with traumatic injuries on ECMO.

However, few civilian centers use LTOWB for trauma resuscitation. We evaluated the early experience and safety of a LTOWB program at a level 1 civilian trauma center.

For patients with severe respiratory failure in the setting of an acute ingestion, veno-venous extracorporeal membrane oxygenation (VV ECMO) can provide salvage therapy. The purpose of this study was to evaluate outcomes in patients with overdose-related need for VV ECMO.

We hypothesized that threshold values using prehospital handheld tissue oximetry would detect occult shock and predict LSI requirements. This was a prospective observational study of adult trauma patients emergently transported by helicopter.

Here, we explore the potential of 3 charge-coupled device (3CCD) imaging values to distinguish between traumatic wounds that heal following closure and those that fail. Previous studies demonstrate that normalized 3CCD imaging values exhibit a high correlation with oxygen saturation and allow for comparison of values between diverse clinical settings, including utilizing different equipment and lighting.

Although simple cut-down procedures are commonly sufficient for the control of blood vessels for distal extremity traumatic amputations, high-thigh or disarticulation wounding patterns often require more complex surgical methods. The following details both the decision-making process and operative techniques for controlling hemorrhage from lower extremity blast injuries.

The accidental ingestion of a foreign object often presents a difficult scenario for the clinician. This includes not only the decision to retrieve the material but also the appropriate technique to use. We present the case of a young asymptomatic girl who swallowed a magnetic activity watch, which was then successfully retrieved with an endoscopic snare.

Rapid determination of tissue viability and surgical restoration of blood flow are desirable, but not always possible. We sought to characterize the response to increasing periods of hind limb ischemia in a porcine model such that we could define a period of critical ischemia (the point after which irreversible neuromuscular injury occurs), evaluate non-invasive methods for characterizing that ischemia, and establish a model by which we could predict whether or not the animal's locomotion would return to baselines levels post-operatively.

Hallmarks of successful treatment involve aggressive surgical debridement and early initiation of systemic antimicrobial therapy. Currently, intravenous anti-fungal therapy commences based on appearance of wounds and patient's clinical course.
View Article and Find Full Text PDFBackground: Trauma-induced hemorrhagic shock produces hemodynamic changes that often result in a systemic inflammatory response that can lead to multiple organ failure and death. In this prospective study, the pathophysiology of a nonhuman primate uncontrolled hemorrhagic shock model is evaluated with the goal of creating an acute systemic inflammatory syndrome response and a reproducible hemorrhage.
Methods: Nonhuman primates were divided into 2 groups.
Background: The clinical importance of extrathyroidal extension (ETE) on outcome of papillary thyroid cancer (PTC), particularly with respect to disease extending to the surgical margin is not well established. This study assessed the importance of surgical margin and extrathyroidal invasion relative to local control of disease and oncologic outcome.
Methods: A retrospective analysis of a prospective institutional endocrine database was conducted on 276 patients with PTC treated between 1955 and 2004 to determine the impact of margin-negative resection (n=199, 72%), disease up to within 1 mm of surgical margin (n=19, 7%), microscopic (n=39, 14%), and gross (n=19, 7%) ETE.
Background: There is evidence that the outcomes of head and neck surgery may differ across racial and ethnic groups. Vocal changes related to the operation are an anticipated risk of thyroidectomy and parathyroidectomy. Race-specific voice outcomes after thyroid and parathyroid operations have not been reported.

Objective: The objectives of this study were, first, to explore agreement between physicians' and their breast cancer patients' pain assessment during subareolar radionucleotide injection; and second, to evaluate potential ethnic differences in ratings.
Methods: A trial was conducted, from January 2006 to April 2009, where 140 breast cancer patients were randomly assigned to standard topical lidocaine-4% cream and 99mTc-sulfur colloid injection, or to one of three other groups: placebo cream and 99mTc-sulfur colloid injection containing NaHCO3, 1% lidocaine, or NaHCO3 + 1% lidocaine.
