Epiaortic ultrasound is an imaging modality that is commonly used to evaluate the ascending aorta for atheroma and other mural lesions during elective cardiac surgery. Its use in contained aortic rupture has not been established. We present a case of thoracic trauma with contained pseudoaneurysm of the ascending aorta. At operation, the precise location of the aortic tear could not be identified by visual inspection, manual palpation, or transesophageal echocardiography. Epiaortic ultrasound was employed and the aortic defect was identified and successfully repaired...

INTRODUCTION: Admission to the intensive care unit (ICU) may be preceded by dramatic events leading to permanent neurological injury. Plasma S100 protein levels are proved to be clinically useful in predicting neurological outcome following cardiac arrest. It is unclear, however, whether this may be extrapolated to a broader population of ICU patients. AIM: To assess the utility of plasma S100 protein in predicting death, permanent neurological damage, or unfavourable outcome at admission to the intensive care unit...

Cardiac rupture (CR) is one of the most serious and life-threatening complications of blunt chest trauma (BCT) usually associated with high mortality. Moreover, its diagnosis and treatment strategies may be extremely challenging for clinicians due to various anatomical localisations of the tear. Whereas most injuries fall under the category of right atrial ruptures, left ventricular lesions represent a rare type of this injury, with greater mortality, particularly in cases of multi-chamber injuries. However, not only cardiac chamber or great vessel ruptures may occur as a result of BCT; a growing number of reports also describe BCT-induced isolated coronary artery injuries, including ruptures...

PURPOSE: Traumatic cardiac injury (TCI) is a challenge for trauma surgeons as it provides a short thera- peutic window and the management is often dictated by the underlying mechanism and hemodynamic status. The current study is to evaluate the factors influencing the outcome of TCI. METHODS: Prospectively maintained database of TCI cases admitted at a Level-1 trauma center from July 2008 to June 2013 was retrospectively analyzed. Hospital records were reviewed and statistical analysis was performed using the SPSS version 15...

BACKGROUND: Thioredoxin (TRX), an endogenous anti-oxidant protein induced in inflammatory conditions, has been shown to increase in plasma and to be associated with outcome in septic patients. This biomarker has never been studied in a trauma setting. We hypothesized that TRX would be increased after trauma and associated with post-injury sepsis. METHODS: Single-centre prospective observational study conducted at the intensive care unit (ICU) at the Karolinska University Hospital, Stockholm, Sweden, a level-1 trauma centre...

Middle cerebral artery (MCA) aneurysms usually arise at the primary MCA bifurcation or trifurcation. Distal MCA aneurysms are rarely considered as sources of aneurysmal subarachnoid hemorrhage (SAH). It has been reported that ruptured distal MCA aneurysms are associated with head trauma, neoplastic emboli, arterial dissection, or bacterial infection. We experienced five cases of ruptured distal MCA aneurysms and evaluated their clinical characteristics. Retrospective analysis of aneurysmal SAH at Kobayashi Neurosurgical Neurological Hospital was performed from January, 2004 to December, 2014...

Fabry disease is an inherited X-linked disorder characterized by the absence (in men) or deficiency (in women) in α-galactosidase A activity that causes a progressive accumulation of glycosphingolipids within lysosomes of cells of all the major organ systems. The subsequent organ damage that manifests in childhood and early adulthood presents a widely variable clinical picture of pain, hypertension, and cardiac, renal, nervous system, and lung dysfunction. We present 2 female patients with Fabry disease who required general anesthesia twice for gynecological and trauma surgery, respectively, and discuss their perioperative management based on new information in the medical literature...

Constrictive pericarditis (CP) represents a form of severe diastolic heart failure (HF), secondary to a noncompliant pericardium. The true prevalence of CP is unknown but it is observed in 0.2-0.4% of patients who have undergone cardiac surgery or have had pericardial trauma or inflammation due to a variety of etiologies. Despite its poor prognosis if untreated, CP is a potentially curable disease and surgical pericardiectomy can now be performed at low perioperative mortality in tertiary centers with surgical expertise in pericardial diseases...

Intense efforts have been made by both industry and academia over the last three decades to produce viable hemoglobin (Hb)-based oxygen carriers (HBOCs), also known as "blood substitutes". Human trials conducted so far by several manufactures in a variety of clinical indications, including trauma, and elective surgeries have failed and no product has gained the Food and Drug Administration approval for human use. Safety concerns due to frequent incidences of hemodynamic, cardiac events, and even death led to the termination of some of these trials...

Blunt Cardiac Rupture (BCR) is a life threatening injury. Majority of patients do not reach the hospital and in those who reach the emergency department, timely diagnosis and treatment is a challenge. The case is about a patient with multiple blunt injuries who presented in shock. Cardiac tamponade was suspected on clinical grounds and on evidence of mediastinal widening on radiograph. In the absence of songography, the diagnosis was confirmed by subxiphoid pericardial window. Emergency thoracotomy revealed a right atrial appendage rupture which was surgically corrected...

BACKGROUND: Organ availability is a consistently limiting factor in transplant surgery. A primary driver of this limitation is donor conversion rate, which is defined as the percentage of eligible donors for whom procurement is actually performed. An alternative way to increase organ availability is through improved utilization of organs from donors after cardiac death (DCD). Recently, a concerted, multidisciplinary effort has been made within our system to improve conversion rates and DCD utilization, thus increasing organ availability...

: The unique aspect of this case study is the unusual history, presentation, ultrasonography, MRI and blood culture results, which lead to the diagnosis and treatment of adductor pyomyositis with a rare organism in a temperate country. The patient presented with a one-day history of malaise, fever, left groin pain and inability to weight bear on the left leg. There was no history of any trauma, predisposing infections or recent travel. Plain radiograph and ultrasound of the hip was normal with no effusion...

AIMS: Current treatments of ventricular arrhythmias rely on modulation of cardiac electrical function through drugs, ablation or electroshocks, which are all non-biological and rather unspecific, irreversible or traumatizing interventions. Optogenetics, however, is a novel, biological technique allowing electrical modulation in a specific, reversible and trauma-free manner using light-gated ion channels. The aim of our study was to investigate optogenetic termination of ventricular arrhythmias in the whole heart...

Air embolism is an infrequent but potentially catastrophic complication. It could be a complication of invasive procedures including surgery, central line placement, positive pressure ventilation, trauma, hemodialysis, pacemaker placement, cardiac ablation, and decompression sickness. Usually, it does not cause any hemodynamic complication. In rare cases, it could lodge in the heart and cause cardiac arrest. We present a case of an 82-year-old white female who underwent computed tomography (CT) guided biopsy of right lung pulmonary nodule...

OBJECTIVES: Sublingual microcirculatory monitoring for traumatic haemorrhagic shock (THS) may predict clinical outcomes better than traditional blood pressure and cardiac output, but is not usually performed until the patient reaches the intensive care unit (ICU), missing earlier data of potential importance. This pilot study assessed for the first time the feasibility and safety of sublingual video-microscopy for THS in the emergency department (ED), and whether it yields useable data for analysis...

BACKGROUND: Cryptogenic stroke frequently occurs in younger patients and has a high risk of recurrence. Consequently, secondary prevention is often suboptimal as there is no known risk factor to target. This case demonstrates an unexpected finding of middle cerebral artery infarction and extensive malignant transformation in a 16-year-old boy more than a day post-admission. The lack of a proven culprit lesion makes this case even more intriguing and subsequently raises questions of cryptogenic mechanisms in the context of unrelated trauma...

Amniotic fluid embolism (AFE) is an unusual cause of life threatening peri partum hemorrhage (PPH). AFE resuscitation is often associated with renal and respiratory insufficiency, and a coagulopathy similar to disseminated intravascular coagulation (DIC). Resuscitation requires immediate recognition and limited use of crystalloid. We present a case of PPH caused by AFE with resultant cardiac arrest, renal and respiratory failure, and DIC-like coagulopathy, whose successful resuscitation was guided by perfusionist-directed serial thromboelastography (TEG)...

Delayed cardiac tamponade (DCT) is a rare and life-threatening complication of catheter ablation performed as a treatment of atrial fibrillation, with few cases described in the medical literature. We present the case of a 57year-old man presenting with DCT 61days following a catheter ablation procedure. To the best of our knowledge, this is the most delayed case of cardiac tamponade (CT) following catheter ablation described in the literature. We also discuss the importance of point of care ultrasound (POCUS) in the diagnosis and treatment of CT...
