OBJECTIVES: Visualizing the needle tip using the short-axis (SA) ultrasound-guided central venous catheterization approach can be challenging. It has been suggested to start the process with the SA approach and then switch to the long-axis (LA); however, to our knowledge, this combination has not been evaluated. We compared the combined short- and long-axis (SLA) approach with the SA approach in a manikin study. METHODS: We performed a prospective randomized controlled cross-over study in an urban emergency department and intensive care unit...

INTRODUCTION: Right heart catheterization (RHC) is routinely performed to assess hemodynamics. Generally, anticoagulants are held prior to the procedure. At our center, anticoagulants are continued and ultrasound guidance is always used for internal jugular vein access. A micropuncture access kit is used to place a 5 or 6 Fr sheath using the modified Seldinger technique. Manual compression is applied for 10-15 min and the patient is observed for at least 2 hours after the procedure. In a retrospective analysis, we investigated the risk of bleeding complications associated with RHC via the internal jugular vein in patients with and without full anticoagulation...

BACKGROUND AND PURPOSE: The cross-sectional area (CSA) of common carotid arteries-internal carotid arteries (CCA-ICAs), vertebral arteries (VAs), and internal jugular veins (IJVs) is influenced by aging. However, the neck vessel CSA can be affected by other factors as well, including subject positioning, hydration, and respiration, especially in longitudinal studies. This study aimed to assess scan-rescan reproducibility of CCA-ICAs, VAs, and IJVs CSA measurements in order to evaluate their feasibility for longitudinal CSA assessments, and to apply the segmentation method on a longitudinal pilot dataset...

Lemierre's syndrome is also known as postangina septicemia, which is commonly caused by Fusobacterium necrophorum also known as Necrobacillus and also by other microorganisms like Staphylococcus, Streptococcus, Peptostreptococcus, and Bacteroides. Though the disease starts as an upper respiratory tract infection, it may spread and cause thrombophlebitis of the internal jugular vein. It may present itself through cranial nerve palsy or sepsis involving distant organs like the lungs or bones. It is also known as forgotten disease because of its rarity...

The incidence of blunt chest trauma (BCT) is greater than 15% of all trauma admissions to the emergency departments worldwide and is the second leading cause of death after head injury in motor vehicle accidents. The mortality due to BCT is inhomogeneously described ranging from 9% to 60%. BCT is commonly caused by a sudden high-speed deceleration trauma to the anterior chest, leading to a compression of the thorax. All thoracic structures might be injured as a result of the trauma. Complex cardiac arrhythmia, heart murmurs, hypotension, angina-like chest pain, respiratory insufficiency or distention of the jugular veins may indicate potential cardiac injury...

The neck, being not protected by skeleton, is vulnerable to external trauma and injury which can involve blood vessels, muscles, nerves, and trachea. Carotid injuries can be potentially life-threatening by hemorrhage and stroke. We present a case of a 26-year-old manual worker who presented a neck injury caused by a metallic projectile. The injury involved the right common carotid artery with an internal jugular vein fistula, and tracheal damage. The patient was managed with surgical repair of the tracheal lesion, reconstruction of the carotid section using a PTFE graft bypass, and ligation of the internal jugular vein...

Limin Dou, Wenhua Yu
Intracranial dural arteriovenous fistulas (DAVFs) are complex intracranial vascular malformations that may lead to hemorrhage. Although the precise mechanisms by which DAVFs occur remain unknown, dural angiogenesis may be a vital factor in its pathogenesis. Nuclear factor erythroid 2-related factor 2 (Nrf2) significantly influences angiogenesis; however, the association between DAVF and Nrf2 remains unclear. Therefore, the present study investigated whether DAVF alters the expression of Nrf2 in an experimental animal model of DAVF...

INTRODUCTION: Exosomes are extracellular vesicles that act as endogenous mediators of the immune response. We have previously shown that exosomes released into mesenteric lymph (ML) following trauma/hemorrhagic shock (T/HS) induce pro-inflammatory cytokine production in macrophages and are involved in the pathogenesis of post-shock acute lung injury. However, the cellular origin of ML exosomes and their role in the post-trauma immune response remains unclear. We hypothesized that exosomes released from damaged-intestinal epithelial cells (IECs) contribute to post-trauma immune dysfunction by altering the function of dendritic cells (DCs), key regulators of the adaptive immunity...

BACKGROUND: Since FDA approval of the Melody valve, transcatheter pulmonary valve replacement (TPVR) has been offered to an expanding population. Limited data exist regarding the safety and feasibility of TPVR in smaller patients. METHODS: All patients weighing <20 kg who underwent catheterization for percutaneous TPVR at four centers were reviewed. RESULTS: Of the 51 patients reviewed, 43 (84%) had successful valve implantation and 8 (16%) were found not to be candidates due to access veins too small (n = 3), coronary artery/aortic root compression (n = 3), and RVOT too large (n = 2)...
