Cardiovascular thrombosis is rare in children and usually occurs in the presence of predisposing conditions, such as indwelling vascular catheters, tumors, aneurysms, ventricular dysfunction, or after surgery. Clots can occur in the cardiac chambers, arteries or veins, or inside conduits. Detection of thrombi is feasible with a variety of magnetic resonance imaging (MRI) techniques, including unenhanced methods but also contrast-enhanced MR angiography. In this essay we illustrate the MRI appearance of cardiovascular thrombosis in children and suggest an imaging protocol based on our clinical experience...

BACKGROUND Native vertebral osteomyelitis (NVO) is a common form of hematogenous osteomyelitis, with Staphylococcus aureus (S. aureus) being the most commonly isolated organism. Dalbavancin is approved by the US Food and Drug Administration (FDA) for the treatment of acute bacterial skin and skin structure infections (ABSSSI) and has a sufficiently promising pharmacokinetic and pharmacodynamic profile to be considered for the treatment of vertebral osteomyelitis. We describe here what is probably the first reported case of using multiple weekly dalbavancin to treat a complicated methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and vertebral osteomyelitis...

A 46-year-old man underwent coronary angiography for stable angina. He developed inferior ST-segment myocardial infarction during the angiography. Intravascular ultrasound (IVUS) findings suggested coronary vasospasm. Intracoronary administration of isosorbide dinitrate restored the coronary flow. This case illustrates the essential role IVUS imaging played in establishing the diagnosis of catheter-induced coronary vasospasm.

Arteria lusoria is the most common anomaly of the aortic arch with an incidence of 0.5%-2.5%. It is mostly diagnosed incidentally while performing imaging for evaluation of other unrelated medical conditions. The aberrant right subclavian artery arises beyond the origin of the left subclavian artery from the aortic arch. This results in a complex right-subclavian-aortic anatomy which leads to difficulty in transradial coronary angiography. This can lead to prolonged procedure time and increased use of catheters by unaware interventionists...

In-stent chronic total occlusion (CTO) represents a challenging lesion subset for percutaneous coronary intervention (PCI), and although a true-to-true lumen crossing is the first-line strategy, a subadventitial approach may become necessary. Here we describe a case of successful in-stent right coronary artery CTO-PCI performed with subadventitial crossing, crushing of the occluded stents, and advancement of a mother-and-child catheter to the distal right coronary artery through the subadventitial space to allow stent delivery...

PURPOSE OF REVIEW: Anesthesiologists are familiar with pulmonary emboli prophylaxis paradigms and many have witnessed acute intraoperative embolization. Clinicians must balance conservative anticoagulation and aggressive intervention in perioperative submassive pulmonary emboli, yet the bulk of the literature excludes surgery as a relative contraindication. This review will summarize the current treatment options for acute pulmonary emboli, drawing attention to special considerations in perioperative submassive pulmonary emboli, and discuss right ventricular monitoring to improve assessment of intervention efficacy...

BACKGROUND AND OBJECTIVE: Serious adverse cardiorespiratory events complicate super selective ophthalmic artery chemotherapy for retinoblastoma in anesthetized children. Their mechanism remains unclear but may be attributed to an autonomic nervous reflex induced by the catheter close to the ophthalmic artery. Inadequate depth of anesthesia during catheter stimulation might be an aggravating factor. Thus, we tested whether deep general anesthesia reduced the incidence of serious cardiorespiratory events...

BACKGROUND: Acute kidney injury requiring renal replacement therapy (AKI-RRT) is associated with high morbidity, mortality and resource utilization. The type of vascular access placed for AKI-RRT is an important decision, for which there is a lack of evidence-based guidelines. METHODS: We conducted a prospective cohort study over a 16-month period with 154 patients initiated on AKI-RRT via either a non-tunneled dialysis catheter (NTDC) or a tunneled dialysis catheter (TDC) at an academic hospital...

The inflammatory process after traumatic fracture and soft tissue injury includes release of inflammatory cytokines and activated polymorph nuclear cells (PMN) that can cause subsequent affected limbs delayed healing and vital organ complications. Analgesics have good effect on relief of the symptom but may cause further burden for hepatic and renal metabolism. Freshwater clam extract (FCE) has been demonstrated to suppress the release of the pro-inflammatory cytokine tumor necrosis factor-α production after hemorrhagic shock, and decrease the level of liver injury marker in rats...

BACKGROUND: Endovascular simulation employing computer, animal, and static models are common and useful adjuncts for teaching endovascular procedures and developing novel, complex endovascular techniques. Unfortunately, these models lack realistic haptic feedback and thus do not faithfully replicate many of the technical challenges associated with clinical endovascular procedures (e.g., arterial calcification, rigidity, and stenosis). We sought to develop a realistic and reproducible perfused cadaver model for endovascular training, device development and research...

MAIN PROBLEM: Cardiac allograft vasculopathy (CAV) can be detected early with intravascular ultrasound (IVUS) but there is limited information on the most efficient imaging protocol. METHODS: Coronary angiography and IVUS of the 3 coronary arteries were performed. Volumetric IVUS analysis was performed and a Stanford grade determined for each vessel. RESULTS: 18 patients were included 18 (range 12-24) months after transplantation. Angiographic CAV severity ranged from none (CAV0) to mild (CAV1) whereas IVUS CAV severity ranged from none (Stanford grade I) to severe (grade IV)...

BACKGROUND: Brain death is associated with significant lung injury and inflammation. This has been associated with worse long-term outcomes for transplanted lungs. Direct peritoneal resuscitation (DPR) reduces systemic inflammation in brain death and improves lung procurement rate. The effect of DPR on macrophage and neutrophil infiltration in the lungs is not known. METHODS: Male Sprague-Dawley rats had a 4F Fogarty catheter inserted into the skull and the balloon inflated until brain death was achieved...

BACKGROUND: The profound inflammatory response associated with brain death is frequently cited as the reason organs procured from brain dead donors are associated with worse graft function. The intestine releases inflammatory mediators in other types of shock, but its role is brain death has not been well-studied. Direct peritoneal resuscitation (DPR) improves visceral organ blood flow and reduces inflammation after hemorrhagic shock. We hypothesized that use of DPR would maintain intestinal integrity and reduce circulating inflammatory mediators after brain death...
