M anipulation of atherosclerotic lesions with wires, cath-eters, balloons, stents, and other intravascular devices during invasive procedures releases atherosclerotic plaque, resulting in distal embolization. This plaque debris leads to no or slow flow as a result of a multitude of factors, including mechanical obstruction of macrovascular and microvascu-lar channels, local platelet adhesion, p...

The clinical and postmortem data from a 14-year-old girl who had transient embolic aortoarteritis are presented. This disease was first described in 1974 by Peiris and Wickremaslnghe in Hindu patients and is characterized by repetitive embolic occlusion of infraand extracranial vessels of the brain, originating from focal thrombotlc lesions in the aorta and its primary branches. The main histop...

BACKGROUND AND PURPOSE The clinical application of Doppler detection of circulating cerebral emboli will depend on a reliable automated system of embolic signal detection; such a system is not currently available. Previous studies have shown that frequency filtering increases the ratio of embolic signal to background signal intensity and that the incorporation of such an approach into an offlin...

 We report a case of Nicolau syndrome in a 15 months old girl following of an intramuscular injection of penicillin 6.3.3 in her left buttock. This case is unique because she developed compartment syndrome in her left calf far from her injection site. Her toe’s tips gangrened in the course of her ailment. We hypothesized that the compartment syndrome might be produced by a probable intra-arteri...

Ischaemic stroke is responsible for up to 80% of stroke cases. Prevention of the reoccurrence of ischaemic attack or stroke for patients who survived the first symptoms is the major treatment target. Accurate diagnosis of the emboli source for a specific infarction lesion is very important for a better treatment for the patient. However, due to the complex blood flow patterns in the cerebral ar...
