... significantly older, less likely to have diabetes mellitus, and more likely to have atrial fibrillation and an embolic source (CE or LAA) compared to other patients. Patients with A-CMI had a higher frequency of macroinfarcts (diameter >20 mm), more often multiple and distributed in single or multiple vessel...

... atrial remodeling and have been associated with ischaemic stroke even in the absence of atrial fibrillation (AF). However, the utility of these P-wave indices in predicting outcomes in patients with embolic stroke of undetermined source (ESUS) has not been studied. The aim of this study is to examine...

...: It is unclear which surrogate of atrial cardiopathy best predicts the risk of developing a recurrent ischemic stroke in embolic stroke of undetermined source (ESUS). Left atrial diameter (LAD) and LAD index (LADi) are often used as markers of left atrial enlargement in current ESUS research, but left atrial...

... and procedure-related embolisms. For a pre-interventional estimation of histologic features and outcome parameters, we assessed the pre-interventional CT attenuation of the thrombi. Methods: We prospectively included all consecutive patients with occlusion of the middle cerebral artery who underwent...

...Kwang-Yeol Park; Pil-Wook Chung; Yong Bum Kim; Heui-Soo Moon; Bum-Chun Suh; Won Tae Yoon Background: Previous diffusion-weighted MRI (DWI) studies have indicated that 10–40% of patients have silent embolism during neurointerventional procedures. However, lesion patterns of the embolisms have...

... recordings during the procedures. Automated emboli detection and classification software (MultiXLab version 2.0) was applied for offline count and analysis. Monitoring using the Filter Wire EX (Boston Scientific) and ACCUNET system (Guidant Corporation) was performed. Results: A total of 9,649 embolic...

...Louis R. Caplan; Ka Sing Wong; Shan Gao; Michael G. Hennerici Traditionally hypoperfusion and embolism are considered separate important causes of stroke in patients with arterial occlusive disease. However, although hypoperfusion and embolism differ in mechanisms and location, they generally...

...O. Sedlaczek; L. Caplan; M. Hennerici We previously posited that impaired washout of emboli was an important mechanism of brain infarction in patients with cerebral hypoperfusion. Hyperviscosity and hypoperfusion enhance thrombus formation promoting embolization of fresh thrombi. Hypoperfusion also...

..., alternative mechanisms, such as cerebral embolism in low-flow territories, may also contribute to clinical symptoms. The incidence of high-intensity transient signals (HITS) and the degree of hemodynamic compromise were studied in symptomatic patients with MMD. Methods: Twenty-four patients (17 female, 7 male...

... and with a peak systolic flow velocity of ≧210 cm/s in the stenosis showed microembolic signals at a rate of 3–25 events/h, despite effective anticoagulation. All these 5 patients had a lesion pattern on cranial CT or MRI scan suggesting embolic origin. All the asymptomatic patients (n = 15) and all the patients...

Matjucha Objectives: To identify the most likely mechanisms of retinal ischemia and embolism in a hospital-referred population, and to determine the frequency of recurrent vascular events during...

.... It is known that, besides dislodgement of pre-existing intra-atrial thrombi, the ‘stunned’ atrium after CV is an important cause of thrombus formation and subsequent embolism. We investigated whether CV of AF is associated with occurrence of circulating microemboli (ME) representing a sensitive marker...

... recurrent TIAs during the observation period, whereas none of the patients without MES suffered a recurrent ischemic event. In the acute phase following stroke, ongoing, emerging and vanishing embolization in some patients may reflect individual active processes of remodelling, healing and disruption...

... in the jugular vein of patients with prosthetic valves would clearly argue for gaseous embolic material, since formed emboli are unable to cross through the capillaries. Methods and Results: Twenty-five patients with artificial heart valves, 15 patients with asymptomatic carotid artery disease, and 25 normal...

... histology revealed a significant component of incompletely infarcted brain. Clinicopathological data suggested that the underlying mechanism was likely to have been cardioembolic in 3 cases, and possibly embolic from heart or aortic arch in a further 5. Two cases were due to ipsilateral carotid artery...

... the carotid arteries or the heart. Yet, studies on subgroups of patients with distinct cardiac sources of embolism are still limited. The same holds true for investigations on the relationship between microembolization and hemorheological parameters. A total of 142 patients suffering from left ventricular...
