Endovascular management of intracranial aneurysms using detachable platinum coils (Guglielmi detachable coils, Target Therapeutics, Fremont, CA) was introduced in 1990 by Guido Guglielmi, an Italian neurosurgeon. Working in collaboration with Vinuela and others at the University of California at Los Angeles, along with Target Therapeutics, endovascular obliteration of aneurysms became a common ...

A 50 yo female with PSC and a bleeding duodenal varix (DV) was evaluated for possible enbucrilate therapy. Endoscopically (Figure 1), the DV was high risk for rebleeding but the relative in-flow and out-flow were uncertain. CT (Figure 2) showed portal vein thrombosis (PVT) and the vascular anatomy of the DV to consist of inflow from the superior mesenteric vein (SMV) with outflow through the DV...

Spinal cord infarction is extremely rare in children, and, similar to cerebrovascular infarcts, the pathogenesis is different from adults. Spinal cord infarcts are most commonly reported in adults in the context of aortic surgery; in children, the etiology is frequently unknown. Fibrocartilaginous embolization is a potential cause of spinal cord infarct in both populations. It is a process that...

OBJECTIVE Staphylococcus aureus is the most frequent causative organism of infective endocarditis (IE) and is characterized by thrombus formation on a cardiac valve that can embolize to a distant site. Previously, we showed that S. aureus clumping factor A (ClfA) and fibronectin-binding protein A (FnBPA) can stimulate rapid platelet aggregation. METHODS AND RESULTS In this study we investigat...

BACKGROUND Dural arteriovenous fistulas are vascular malformations with variable clinical symptoms that range in severity from completely asymptomatic to seizures, dementia, loss of vision and intracranial hemorrhage. Historically, surgical obliteration was the treatment of choice but, more recently, endovascular embolization has become the first-line treatment. The liquid embolic agent Onyx (e...

A 56-year-old manwith pancreatic cancer underwent palliative placement of a biliary self-expanding metallic stent (SEMS) for obstructive jaundice after chemoradiation (nine cycles over 5 months). He presentedwithmelena but denied abdominal pain, nausea/vomiting, or hematemesis. Hemoglobin concentration was 6.5g/dL and serum bilirubin 1.0mg/dL (normal: 13.8–17.2g/dL and <1.9mg/dL, respectively)....

Primary neoplasms of the heart are rare. Malignant cardiac myxoma, or so-called myxosarcoma, accounts for about 6% of primary malignant cardiac tumors. Cerebral metastasis of malignant cardiac myxoma is extremely rare; only three cases have been reported and two of them included an autopsy study. The case described herein is the first reported brain metastasis combined with multiple cerebral an...

Intrapulmonary arteriovenous anastomoses (IPAVA) allow large diameter particles of venous origin to bypass the pulmonary capillary bed and embolize the systemic arterial circulation. IPAVA have been routinely observed in healthy humans with exercise, hypoxia, and catecholamine infusion, but the mechanism by which they are recruited is not well-defined. We hypothesized that beta-adrenergic recep...

Congenital intracranial tumors are rare. If such a lesion is detected before birth, it is usually an incidental finding on fetal ultrasonography. The definition of a "congenital" tumor is controversial. The authors report the case of a "definite" congenital glioblastoma multiforme (GBM) diagnosed with the aid of ultrasonography and fetal magnetic resonance (MR) imaging in the 37th week of gesta...

Current Opinion in Cardiology 2011, 26:472–479 Purpose of review To describe cholesterol embolization syndrome (CES) and its risk factors, pathophysiology, clinical presentation, diagnosis and treatment. Recent findings To date, no specific diagnostic test (other than biopsy) for CES has been developed. Effective treatments for CES are yet to be developed. Summary CES (also referred to as chole...
