Noncompressible torso hemorrhage (NCTH) and shock is a leading cause of trauma-related mortality and evidence suggests that survival from this injury pattern has not improved in decades. As such, innovating new approaches and devices, including technologies which can be used by providers within a short of time after severe injury, is a priority for the military. Guided by wartime observations, and through partnerships with civilian academia and private investment, the military has led an effort to define resuscitative endovascular balloon occlusion of the aorta (REBOA) and assess its potential to address this problem...

Raphaël André, Jörg D Seebach
Erdheim-Chester disease is a rare multisystemic non-Langerhans histiocytosis with about 500 reported cases. Typical features include retroperitoneal and perirenal fibrosis (hairy kidney), periaortitis with a coated aorta, osteosclerosis of the lower limbs, and sometimes exophthalmia or diabetes insipidus. Histology is the cornerstone for diagnosis showing an infiltrate with foamy histiocytes and occasional multinucleated giant cells (Touton cells). There is no standard treatment regimen, current options include corticosteroids, interferon alpha, systemic chemotherapy, and radiation therapy ; however, a better understanding of the pathophysiological mechanisms has allowed the emergence of novel targeted treatments such as vemurafenib, imatinib, and anakinra...

C Reeps, S Schellong, R T Hoffmann
Depending on the type and acuteness, diseases of the aorta can be imaged by a variety of techniques. Modalities and quality of imaging have developed rapidly in recent years. In combination with the clinical assessment of patients, the results obtained by imaging determine the further management. They not only establish the underlying diagnosis but provide the information essential for indications, planning and reassessment of therapy, as well as for evaluation of the clinical course and surveillance. Whereas conventional catheter-guided angiography and intravascular ultrasound are only used in exceptional cases and then in conjunction with interventional therapy, cross-sectional imaging modalities, such as contrast-enhanced computed tomography (CT) angiography and magnetic resonance imaging (MRI) are nowadays the mainstay of diagnostics...

INTRODUCTION: It remains unclear whether exposure to repeated positive acceleration (+Gz) can exacerbate endothelial dysfunction on the basis of hyperlipidemia. The aim of this study was to investigate the effect of repeated +Gz exposure on endothelial function in high-fat-diet-induced hyperlipidemic rats. MATERIAL AND METHODS: Male Sprague-Dawley rats were randomly divided into control, repeat +Gz exposure, high-fat diet (HFD), and +Gz + HFD groups. The rats in the +Gz group were exposed to +Gz and the rats in the HFD group were fed a diet with 2% cholesterol...

INTRODUCTION: Many structural and functional damages are observed in cells and tissues after reperfusion of previously viable ischemic tissues. Acute ischemia reperfusion (I/R) injury of lower extremities occurs especially when a temporary cross-clamp is applied to the abdominal aorta during aortic surgery. Research regarding the treatment of I/R injury has been increasing day-by-day. In this study, we aimed to investigate the effect of picroside II on skeletal muscle of rats experiencing simulated I/R...

OBJECTIVE: To assess the prevalence of congenital heart disease (CHD) in Germany in relation to phenotypes, severity and gender. DESIGN: Cross-sectional registry study. SETTING: We analyzed data from patients with CHD born between 1996 and 2015. PATIENTS: A total of 26 630 patients, registered with the NRCHD, were born between 1996 and 2015. 10 927 patients were excluded from the current analysis due to prior registration with the NRCHD under the German PAN Prevalence Study, which showed a potential bias in the inclusion of this patient population (proportion of mild cardiac lesions was comparatively high due to improved diagnostic capability for earlier identifying minor lesions)...

Aortitis of ascending aorta is a recognized complication of ankylosing spondylitis (AS). There are a few published cases of diffuse aortitis and aorta collaterals inflammation that fulfill Takayasu's arteritis (TA) criteria coexisting with AS. We have reviewed published cases from literature and present three new cases of such coexistence. We identified three patients who fulfilled definite AS New York criteria in our Takayasu's vasculitis cohort of eight patients. One of this patients had been diagnosed with Crohn's disease before AS and TA diagnosis...

We report a 23-year-old woman admitted post cyclist versus heavy goods vehicle accident in December 2014. This was the second case the life-saving procedure, that is, resuscitative endovascular balloon occlusion of the aorta (REBOA) was performed on at the roadside. This advanced procedure was performed due to the extensive haemorrhage from this patient's complex pelvic fracture . As a result of REBOA, the patient consequently lost her left lower limb and underwent a variety of complex pelvic and lower limb surgeries...

BACKGROUND: Marfan syndrome is a genetic disease, presenting with dysfunction of connective tissues leading to lesions in the cardiovascular and skeletal muscle system. Within these symptoms, the most typical is weakness of the connective tissue in the aorta, manifesting as aortic dilatation (aneurysm). This could, in turn, become annuloaortic ectasia, or life-threatening dissection. As a result, life-saving and preventative cardiac surgical interventions are frequent among Marfan syndrome patients...

Abstract Synthetic or biologic materials are usually used to repair vascular malformation in congenital heart defects; however, non-autologous materials show both mismatch compliance and antigenicity, as well as a lack of recellularization on its surface. Here, we constructed a tissue-engineered vascular patch (TEVP) using decellularized extracellular matrix (ECM) scaffold obtained from excised human aorta during surgery, which was seeded with patient-derived bone marrow CD34-positive (CD34+) progenitor cells...

Originating as a single vessel emerging from the embryonic heart, the truncus arteriosus must septate and remodel into the aorta and pulmonary artery to support postnatal life. Defective remodeling or septation leads to abnormalities collectively known as conotruncal defects, which are associated with significant mortality and morbidity. Multiple populations of cells must interact to coordinate outflow tract remodeling, and cardiac neural crest has emerged as particularly important during this process. Abnormalities in cardiac neural crest have been implicated in the pathogenesis of multiple conotruncal defects, including persistent truncus arteriosus, double outlet right ventricle, and tetralogy of Fallot...

Abdominal aortic aneurysm is a disease seen in the elderly. Without intervention, an aneurysm can rupture which leads to death in most cases. Surgical resection was the gold standard treatment for many years but since two decades, endovascular repair has surged drastically. Less invasive and morbid than open repair, this technique has significantly evolved in the recent years. Nowadays the whole aorta can be treated with endovascular techniques in expert hands. This article presents an overview of different endovascular solutions and innovations in the management of aortic aneurysms...
