A 77-year-old man with myelodysplastic syndrome presented with fever and acute renal failure, followed by right-sided hemiparesis, neglect, and aphasia. Neuroimaging revealed a left parietal-occipital ICH with extensive edema. T2-star susceptibility weighted angiography (SWAN) revealed multiple microhemorrhages within the swollen hemisphere (figure 1). Autopsy findings included perivesical/peri...

75-year-old woman was admitted with fever, chills, altered mentation, and right-sided weakness. A month earlier, she had undergone catheter radiofrequency ablation for treatment of chronic atrial fibrillation. A magnetic resonance imaging scan of her brain revealed septic emboli with multiple bilateral cerebral and cerebellar infarcts, as well as extensive bilateral leptomeningeal enhancement. ...

A venous air embolism and paradoxical air embolism (PAE) are serious complications in patients undergoing a hepatectomy. We report a case of PAE and cerebral infarctions in a patient undergoing a hepatic resection using a Cavitron Ultrasonic Surgical Aspirator (CUSA®). A 65-year-old woman underwent a left lobe hepatectomy. During the middle phase of the liver resection with CUSA®, there was a s...

It is now generally believed that the majority of strokes are caused by emboli from distal sites, rather than by local haemorrhagic or occlusive processes. The discovery that emboli of various types can be detected using Doppler ultrasound as they are carried through the major cerebral arteries has led to a new field of study, which appears to have considerable potential both in research and cl...

UNLABELLED Background- Power motion-mode transcranial Doppler (TCD) (PMD) is a new, multigated technique that may simplify and enhance detection of embolus. We developed criteria for emboli detection using PMD. Then, we performed a blinded comparison of transcranial PMD with single-gate spectral TCD in TCD bubble study patients. METHODS Patients with right-to-left shunt as detected with stand...

BACKGROUND Stroke after open heart surgery is a major cause of morbidity and mortality. Up to 60% of intraoperative cerebral events are caused by emboli generated by manipulations of the aorta during surgery. This is the first animal study evaluating the safety and efficacy of a novel aortic cannula designed to extract solid and gaseous emboli during cardiac surgery. METHODS Seven domestic pi...

Hereditary Haemorrhagic Telangiectasia (HHT), or Osler-Weber-Rendu syndrome is an uncommon autosomal dominant multi-organ condition of vascular dysplasias. We describe a 19 year old Indian female who presented with cerebral abscess secondary to paradoxical emboli from pulmonary arteriovenous malformations (PAVMs) associated with HHT. Cerebral, pulmonary, hepatic and gastrointestinal involvement...

Percutaneous intravenous devices are an essential component of modern health care. Although they are generally associated with a low incidence of vascular access device-related sepsis, the events following a vascular catheter-related sepsis can be clinically significant and difficult to treat. Here we report a case of Portacath-related sepsis with Serratia marcescens resulting in cerebral and p...

Fourteen cases of inadvertent iatrogenic embolization of cerebral vessels occurring in a consecutive series of 3,731 angiographies in infants and children were studies. The incidence of embolization(0.9% of all patients ond 0.4% of all angiographic examinations) was about the same as has been reported in adults, but the clinical consequences were much milder, only one patient having documented ...

Pituitary Apoplexy: The Role of A theromalous Emboli • Patients with clinically unsuspected pituitary adenomas may present with sudden severe frontal headaches, stupor, ophthalmoplegia, meningeal irritation, compression of the optic nerves or chiasm, and abnormal cerebrospinal fluid. These findings are commonly misinterpreted as due to a ruptured cerebral aneurysm. The clinical features and con...
