Our data does not show a net benefit in selective shunting unless the patient has sustained a stroke prior to surgery. The decision to shunt, however, when there is electrical dysfunction after carotid clamping should be based not only on the EEG but also on the clinical signs and computed tomography (CT) scan. Since the need for protection is unpredictable by angiographic or clinical criteria, the benefit of EEG monitoring may be in reducing the incidence of shunting in those patients whose tracing remains normal after clamping. However, the use of shunts may introduce a risk of stroke due to technical error that is equal or greater than the risk of stroke due to hemodynamic ischemia.
EEG COST SERIES
Our series does not clearly establish the advantages of EEG monitoring, which is expensive (+375/patient) and may not detect ischemia in all areas of the brain. The EEG did not change in three patients who had lacunar infarcts prior to surgery and who awoke with a worsened deficit. Patients who suffered strokes prior to surgery were more at risk to develop a perioperative stroke (three per cent) than those not suffering prior strokes (0.3%). Technical problems were more common when shunts were used (five per cent) than when they were not (0.9%). Nine of the 15 were associated with a technical problem of either thrombosis of the internal carotid artery (five) or emboli (four). Fifteen patients suffered perioperative strokes (2.6%). Patients with contralateral carotid occlusion exhibited EEG changes in 37% (28/76) of operations.

The frequency of EEG changes, as related to cerebral vascular symptoms, was as follows: transient ischemic attacks, seven per cent (19/259) completed strokes, 37% (36/98) vertebral basilar insufficiency, 24% (32/135) asymptomatic, 21% (15/71). EEG changes occurred in 102 patients (18%).

EEG COST CODE
They should be able to give this information before any appointment is booked for the test, though you may need to call with a code for that test to help them find the correct answer. The billing department will be able to look up the information and give a comprehensive breakdown of the actual charges. The best way to determine the actual cost for an EEG Test is to call the hospital or doctor's office and request the information. A low income may provide the test for significantly less than the person with insurance is charged. Most doctors or hospitals will discount the charges if there are extenuating circumstances with a person's income. Given the differences in insurance plans, a person may pay more or less for an EEG test.Īn individual without insurance is subject to the cost the doctor or hospital normally charges. Some insurance companies like Kaiser Permanente provide a bill for tests completed, but will not charge for an office visit unless the office visit was on the same day the test was completed. There may also be the charge for the office or hospital visit depending on how the test was run. For example, anyone with insurance with an 80/20 plan would pay 20% of the total cost of the test. Those with insurance will most likely pay a percentage of the test. Therefore, it is difficult to say if this is a true value.

The cost of an EEG Test will vary depending on your insurance and the hospital you are obtaining the test from. EEG (ELECTROENCEPHALOGRAPH) An EEG uses surface sensors to detect the brain’s electrical patterns (known as brainwaves ).Common brain imaging techniques such as MRIs, CAT scans and x-rays are built to measure brain structure.
