BACKGROUND: Extracorporeal life support (ECLS) describes the use of blood perfusion devices to provide advanced cardiac or respiratory support. Advances in percutaneous vascular cannula insertion, centrifugal pump technologies, and the miniaturization of extracorporeal devices have simplified ECLS. The intention of this discussion is to review the role of ECLS as a potential rescue method for emergency department (ED) clinicians in critical clinical scenarios and to focus on the prerequisites for managing an ECLS program in an ED setting...

Vascularized toe joint transfers are used for proximal interphalangeal (PIP) or metacarpophalangeal reconstruction of the fingers in children or young adults, as an alternative to joint arthroplasty. In children, this reconstruction aims to restore range of motion (ROM) and the growing capacities. The typical donor sites are the PIP or metatarsophalangeal joints of the second toe. These transfers are performed with short vascular pedicles in order to simplify the surgical technique and reduce the overall morbidity...

Although management paradigms for certain arterial trauma, such as aortic injuries, have moved towards an endovascular approach, the application of endovascular techniques for the treatment of peripheral arterial injuries continues to be debated. In the realm of peripheral vascular trauma, popliteal arterial injuries remain a devastating condition with significant rates of limb loss. Expedient management is essential and surgical revascularization has been the gold standard. Initial clinical assessment of vascular injury is aided by readily available imaging techniques such as duplex ultrasonography and high resolution computed tomographic angiography...

Hypothenar or thenar hammer syndrome (HHS) and hand-arm vibration syndrome (HAVS) are diseases caused by acute or chronic trauma to the upper extremities. Since both diseases are generally related to occupation and are recognised as occupational diseases in most countries, vascular physicians need to be able to distinguish between the two entities and differentiate them from other diagnoses. A total of 867 articles were identified as part of an Internet search on PubMed and in non-listed occupational journals...

Retinoblastoma (RB) is a well‑vascularized tumor dependent on angiogenesis. The present study aimed to explore whether microRNA (miR)‑182 regulates cell viability, invasion and angiogenesis in RB via the phosphatidylinositol‑3‑OH kinase (PI3K)/protein kinase B (AKT) signaling pathway and by targeting cell adhesion molecule 2 (CADM2). The expression levels of miR‑182 and CADM2 were initially detected in RB tissues from patients with RB who underwent ophthalmectomy, and normal retinal tissues collected from other trauma patients who underwent eye enucleation...

Acquired diaphragmatic defects occur secondary to trauma, infection, surgery or neoplasm. These defects can lead to abnormal thoraco-abdominal fistulous communications also. Examples of surgically created diaphragmatic defects are omental, colonic interposition and vascular grafts. Regardless of etiology, these transdiaphragmatic communications provide a direct path for spread of pathology between the abdomen and thorax. If left untreated and unrecognized, these fistulae portend a high morbidity and mortality...

INTRODUCTION: Impalement injury is an uncommon presentation, and penetrating chest injuries account for 1% to 13% of thoracic trauma hospital admissions. The vast majority of patients with penetrating thoracic trauma who survive to reach the hospital alive can be managed nonoperatively. Nevertheless, in 10% to 15% of cases, emergency operation is necessary due to the associated hemorrhagic shock and visceral injury. CASE PRESENTATION: Here, we report on a 39-year-old male, a construction worker, who fell down from a height of a construction site, landing ventrally on a clump of iron rods with 4 projecting heavy metallic rods penetrating into his thorax and head (scalp pierced only)...

It is known that in less than a third of patients presenting sudden hearing loss, the disorder can be attributed to viral infection, trauma, neoplasms, and vascular and autoimmune diseases. However, the role of the HIV in the onset of this disease has not yet been well described. A 46-year-old female, in an immunosuppression state induced by HIV infection, presented with sudden bilateral hearing loss, with no improvement despite treatment. Several mechanisms were reported by which the virus could induce damage to the auditory pathway...

Cirsoid aneurysms, also known as scalp arteriovenous malformations (AVM), are rare congenital extracranial vascular anomalies that often present as an enlarging pulsatile scalp mass. A 14-yr-old male presented with a pulsatile scalp lesion that was first noticed 3 yr prior and had progressively enlarged. No history of trauma was reported. MRI demonstrated a 4 cm wide and 2 cm tall nidus and catheter angiography was performed to further define the vascular supply and drainage. The patient underwent transvenous endovascular embolization followed by surgical excision via a bicoronal incision, as shown in this operative video...

Surgical interventions on blood vessels bear a risk for intimal hyperplasia and atherosclerosis as a consequence of injury. A specific feature of intimal hyperplasia is the loss of vascular smooth muscle cell (VSMC) differentiation gene expression. We hypothesized that immediate responses following injury induce vascular remodeling. To differentiate injury due to trauma, reperfusion and pressure changes we analyzed vascular responses to carotid artery bypass grafting in mice compared to transient ligation. As a control, the carotid artery was surgically laid open only...

BACKGROUND: Angiopoietin-1 (Agpt-1) and Agpt-2 are cytokine regulators of vascular endothelial integrity. Elevated plasma Agpt-2 levels and ratios of Agpt-2:Agpt-1 are associated with adverse outcomes in adult trauma and pediatric sepsis populations. However, the behavior of the angiopoietins after pediatric trauma has not been characterized, and their relationship to endothelial glycocalyx damage, indicated by plasma syndecan-1 (Syn-1) levels, has not been established. METHODS: We performed a secondary analysis of prospectively collected data from 52 pediatric trauma patients and 12 control patients at a level one pediatric trauma center from 2013 to 2016...

Surgical sutures represent the gold standard for wound closure, however, their main purpose is still limited to a mechanical function rather than playing a bioactive role. Since oxygen and pro-regenerative growth factors have been broadly described as key players for the healing process, in this study we evaluated the feasibility of generating photosynthetic sutures that, in addition to mechanical fixation, could locally and stably release oxygen and recombinant human growth factors (VEGF, PDGF-BB, or SDF-1α) at the wound site...
