Systemic emboli released during total knee replacement have been implicated as a cause of peri-operative morbidity and neurological dysfunction. We undertook a prospective, double-blind, randomised study to compare the cardiac embolic load sustained during computer-assisted and conventional, intramedullary-aligned, total knee replacement, as measured by transoesophageal echocardiography. There ...

Embolic material was seen in the right atrium during one or more phases of revision total hip arthroplasty (THA)in 17 of 21 ASA Class II or Class III patients (77%) who were monitored with transesophageal echocardiography (TEE). The largest volume of embolic material occurred during preparation and insertion of cemented femoral components. Multiple occurrences of embolization during the procedu...

A rare congenital myocardial defect, known as left ventricular hypertrabeculation/non-compaction (LVHT), has been occasionally described associated with thrombus formation with a potential systemic embolic risk, but its association with ischemic strokes remains controversial. We report a case of ischemic stroke in a patient with severe LVHT and ventricular dysfunction as a possible etiologic sy...

The extensive vascularity of extra and intracranial neoplasms is vulnerable to superselective intraarterial injection of embolic particles. The goal is to inject embolic material such as polyvinyl alcohol particles, gelfoam powder, fibrin glue, microfibrillar collagen, or gelatin microspheres until the vascular blush is completely obliterated. The angiographic supply pattern determines the like...

Takayasu's arteritis is a disease that affects large vessels and may cause neurological symptoms either by stenoses/occlusions or embolisms from vessels with an inflammatory process. Transcranial Doppler (TCD) ultrasound can provide useful information for diagnosis and monitoring during the active phase of the disease. Cerebral embolic signals can be detected by TCD and have been considered a r...
