BACKGROUND: Cerebral venous air embolism (CVAE) is a severe clinical condition related to unfavoured outcome in patients with neurological impairment. CVAE may occur secondary to arterial or venous interventions. A rare mechanism of CVAE is retrograde embolism that is characterized by gas flow in a direction opposite to that of the normal blood flow. CASE REPORT: A 69-year-old female was admitted to our hospital with shortness of breath and abdominal pain. Abdominal computed tomography (CT) revealed intramural gas in the bowel and free gas in the mesenteric veins and portal vein...

INTRODUCTION: Systemic air embolism (SAE) is a rare but serious complication following endoscopic procedures. It may occur with or without direct vessel injury. The aim of this work is to review cases of SAE following endoscopy without proven vessel injury. METHODS: In this systematic review PubMed database was screened for SAE following endoscopy from 1990 to 2015. Only cases without proven major vessel injury were included in the analysis. Including one case of SAE after colonoscopy from our hospital the analysis comprised 40 cases...

Cardiac papillary fibroelastoma is reported to be the 2nd most common cardiac tumor following myxoma. Owing to the risk of embolism, early surgical excision is the treatment of choice. We report a case of effective anticoagulation therapy prior to surgical excision of an aortic valve papillary fibroelastoma. A 78-year-old man was admitted to our hospital because of transient cerebral ischemic attack. The symptom was relieved in a short period. Echocardiography revealed a tumor at the aortic valve. Cardiac computed tomography revealed a sea-anemone-like appearance of the tumor...

While the etiology of ischemic stroke is heterogeneous, approximately 20%-40% of all stroke cases result from cardiac or aortic origin. Transesophageal echocardiography (TEE) has become the reference standard modality for the detection of potential sources of cerebral embolism. Because of the advances in computed tomographic (CT) technology, cardiac CT can be used in the evaluation of potential cardioembolic sources. During the past decade, cardiac CT has been tested and compared with TEE for the diagnosis of cardioembolic sources...

A 62-year-old woman had a prior ischemic stroke in the right temporal lobe with dysarthria and dysesthesia of the left hand. Embolic stroke of undetermined source (ESUS) was diagnosed and warfarin was administered. However, transient ischemic attack recurred upon admission to our hospital. Paroxysmal atrial fibrillation and cerebral arterial stenotic lesions were absent. Transesophageal echocardiography revealed a mobile hyperechoic structure on the aortic valve indicating papillary fibroelastoma. She was diagnosed with a brain embolism due to the intracardiac tumor which was surgically excised and pathologically confirmed as papillary fibroelastoma...

BACKGROUND: Retrograde brain embolization from complex plaques of the proximal descending aorta (DAo) has been identified as a new potential mechanism of stroke. Our purpose was to identify predictors of increased retrograde aortic blood flow indicating an elevated risk of brain embolization from the DAo. METHODS: A total of 485 patients with acute ischemic stroke were prospectively included and underwent transesophageal echocardiography. Blood flow velocities in the proximal DAo were studied using 2D pulse-wave Doppler ultrasound...

A brain arteriovenous malformation (AVM) is a congenital malformation of the vascular system, in which an abnormal short circuit (vascular malformation) connects cerebral arteries and veins. When the brain AVMs are diagnosed, the majority of them must be closed with surgical or endovascular treatment, because only a small portion of the brain AVMs remain asymptomatic during the patient's life. Endovascular transarterial embolization using Onyx Liquid Embolic System is a suitable method for treating brain AVMs...

Quadricuspid aortic valve (QAV) is a rare congenital cardiac defect. Aortic regurgitation is the predominant hemodynamically relevant abnormality in patients with QAV, and the main reason for patients requiring valve surgery. Calcific valve disease of the left heart valves is classified as 'low embolic risk' according to current guidelines. However, it remains an important risk factor of cardiovascular events, including ischemic stroke. A 71-year-old woman presented with new-onset aphasia and hemiparesis of the right side of her body...

BACKGROUND: Ischemic stroke is a rare complication of Churg-Strauss syndrome (CSS) and its pathogenesis has not been well clarified yet. We report a case of cerebral infarction in a patient with CSS due to embolism from a thrombus on the wall of the aorta. CASE: A 39-year-old man had multiple cerebral infarctions with symptoms of mild left hemiparesis and reduced vision. He was clinically diagnosed to have CSS based on remarkable eosinophilia, history of asthma, sinusitis, pulmonary infiltrates, and histologically proven extravascular eosinophilic infiltrates in the specimen of gastric mucosa...

A 52-year-old woman was admitted to our hospital for acute right hemi-paresis, left homonymous hemianopia, and fever. Magnetic resonance imaging of the brain showed multiple cerebral infarctions and transesophageal echocardiography (TEE) revealed a vegetation on the posterior leaflet of her mitral valve. Mitral valve repair was performed under a diagnosis of infective endocarditis (IE). Further multiple cerebral infarctions occurred on the 11th postoperative day, resulting in left hemiplegia and dysarthria...

Only a few cases of Turner syndrome (TS) with ischemic stroke have been reported. Various arteriopathies of the cerebral arteries, including fibromuscular dysplasia, congenital hypoplasia, moyamoya syndrome, and premature atherosclerosis have been assumed to be the cause of ischemic stroke in TS. There has been no case report of a TS patient presenting with an embolic stroke pattern without any cerebral arteriopathy. A 28-year-old woman with TS was referred to our hospital because of abnormal brain magnetic resonance imaging (MRI) findings...

Here we report first 2 cases of patients with nonvalvular atrial fibrillation with acute cardioembolic stroke in whom thrombi in the left atrial appendage (LAA) were resolved by edoxaban administration. Case 1 reports an 86-year-old woman who suddenly showed right hemiparesis and aphasia due to occlusion of the left middle cerebral artery. She received mechanical thrombectomy and recovered neurologically. Transesophageal echocardiography (TEE) performed on day 1 demonstrated thrombus in the LAA. The thrombus was resolved on day 13 after initiation of edoxaban (30 mg once daily) instead of warfarin, which was administered before stroke onset...

A mobile thrombus in an otherwise normal ascending aorta is rare, but it should be thoroughly searched for in patients with unexplained cerebral or peripheral embolism. We report the case of a 49-year-old man admitted for right lower quadrant abdominal pain secondary to embolic renal infarction. Echocardiography and computed tomography of the chest revealed a 2.5 cm × 1.5 cm hypermobile mass at the distal ascending aorta, which was otherwise normal. No hypercoagulable condition could be identified. The mass was successfully removed with the patient under deep hypothermic circulatory arrest and was confirmed to be a thrombus...

BACKGROUND: Systemic embolism, especially septic embolism, is a severe complication of infective endocarditis (IE). However, concurrent embolism to the brain, coronary arteries, and spleen is very rare. Because of the risk of hemorrhage or visceral rupture, anticoagulants are recommended only if an indication is present, e.g. prosthetic valve. Antiplatelet therapy in IE is controversial, but theoretically, this therapy has the potential to prevent and treat thrombosis and embolism in IE...
