Computational particle-hemodynamics analysis and geometric reconstruction after carotid endarterectomy
Transient three-dimensional laminar incompressible dilute suspension flow in rigid in-plane carotid artery bifurcations has been solved with a user-enhanced finite-volume program. Instantaneous velocity vector and wall shear stress vector fields illustrate strong "disturbed flow" patterns. Implications of elevated surface contours of hemodynamic wall parameters, indicating such disturbed flows,...
متن کاملNeuropsychological changes after carotid endarterectomy.
Carotid endarterectomy (CEA), performed to prevent stroke, could lead to changes in cognitive functions. Sixty-four patients with severe carotid stenosis undergoing CEA treatment were evaluated by means of a detailed neuropsychological assessment before (baseline), from one to two weeks (1st follow up) after and 3 months (2nd follow up) after surgical operation. A significant post-CEA improveme...
متن کاملSignificance of EEG changes at carotid endarterectomy.
Visually apparent EEG changes associated with clamping the internal carotid artery appeared in 55 of 176 consecutive patients (31%) undergoing carotid endarterectomy without shunt. Attenuation of higher frequency activity was the most common change. Changes were moderate in 33 patients (19%) and major in 22 (12.5%). Major changes usually commenced earlier than less severe alterations. EEG chang...
متن کاملNeuropsychometric changes in patients after carotid endarterectomy.
BACKGROUND AND PURPOSE One hundred twelve patients undergoing elective carotid endarterectomy for symptomatic and asymptomatic carotid artery stenosis were enrolled in a prospective study to evaluate the incidence of change in postoperative cerebral function. METHODS Patients were evaluated preoperatively and postoperatively before hospital discharge and at follow-up 1 and 5 months later with...
متن کاملRedo carotid endarterectomy versus primary carotid endarterectomy.
BACKGROUND AND PURPOSE Several authorities have recently advocated carotid stenting for recurrent carotid stenosis because of the perception that redo surgery has a higher complication rate than primary carotid endarterectomy (CEA). This study compares the early and late results of reoperations versus primary CEA. METHODS All reoperations for recurrent carotid stenosis performed during a rece...
