Psychological testing, cerebral blood flow (CBF) measurement, and computed tomographic scan were performed before and 3 months after operation in 31 patients subjected to endarterectomy of the internal carotid artery (ICA) because of transient ischemic attacks and in 11 control patients operated on for atherosclerosis of the lower extremities. In(More)
Psychological testing was performed in 25 patients (mean age 56 years) with transient ischaemic attacks and/or minor strokes and with angiographically verified internal carotid artery stenosis. The effects of carotid endarterectomy on intellectual functions were evaluated postoperatively at 2 weeks and 8 months respectively. Preoperatively the mean test(More)
Repeated cerebral blood flow (CBF) measurements with xenon-133 inhalation and single photon emission tomography were performed in a patient suffering a minor stroke with subsequent orthostatic-provoked transient ischemic attacks (TIA's). Angiography revealed a thread-like internal carotid artery and an occluded external carotid artery on the side of the(More)
Abxtract: Cerebral Blood Flow and Internal Carotid A rtery Flow During Carotid Surgery • In a series of 17 patients operated on for stenosis of the internal carotid artery, measurement of the blood flow in the internal carotid artery by a squarewave electromagnetic flowmeter was performed simultaneously with measurement of the regional cerebral blood flow(More)
This prospective randomized study deals with the changes in magnitude and distribution of the extracellular fluid volume (ECV) and the relation between such changes and the plasma colloid osmotic pressure (COPP) in patients having abdominal aortic surgery. Two groups of thirteen patients each received whole blood to replace the blood loss. One group (ALB)(More)
Serial measurements of cerebral blood flow (CBF) were performed in 56 patients before and one to four times after uncomplicated carotid endarterectomy. The findings were related to the ratio between internal carotid artery (ICA) and common carotid artery (CCA) mean pressures. Within the 1st postoperative day CBF increased by a median of 37% in the(More)
