a lumped parameter method to calculate the effect of internal carotid artery occlusion on anterior cerebral artery pressure waveform

1024x768 normal 0 false false false en-us x-none ar-sa background and objective: numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. one physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. in this study, we can predict hem...

A Penetrating Pellet Jeopardizing Internal Carotid Artery

Anomalous internal carotid anastomosis to contralateral anterior cerebral artery.

BACKGROUND Many anomalies and variants in vascular anatomy have been reported in relation to the anterior cerebral artery (ACA). PATIENTS AND METHODS We encountered an apparently novel anomaly in a 30-year-old man admitted for disturbance of consciousness following a traffic accident. Computed tomography revealed an acute subdural hematoma and subarachnoid hemorrhage. RESULTS AND CONCLUSION...

[Traumatic occlusion of the internal carotid artery].

A COMPIEETE review of published eases of internal carotid artery occlusions in children has been given by Fischer and Friedmann in 19561 and by Wisoff and Rothballer in 1961.2, 3 Frantzen, Jacobsen, and Tlierkelsell in 19614 reported three cases of traumatic occlusioil of the internal artery in children. The cause of a traumatic occlusion of the internal carotid artery might be a direct lesioni...

Hemodilution improves cerebral hemodynamics in internal carotid artery occlusion.

BACKGROUND AND PURPOSE Hemodilution may be a useful form of therapy for patients with carotid occlusive disease and hemodynamic ischemia. Accordingly, we evaluated the effects of hemodilution on cerebral hemodynamics and oxygen metabolism in patients with carotid artery occlusion. METHODS Using positron emission tomography, we analyzed regional cerebral blood flow, oxygen extraction fraction,...
