Table 1 Characteristics of the study population.
| Variable | Overall (n=59) |
|---|---|
| Age | 62±8 |
| Body mass index | 25±3 |
| ASA | |
| II | 16 (26%) |
| III | 43 (73%) |
| Cerebral infarction | 48 (81%) |
| Hypertension | 39 (66%) |
| Diabetes mellitus | 18 (31%) |
| Coronary heart disease | 11 (19%) |
| Severe stenosis of contralateral ICA | 9 (15%) |
| Collateral circulation | 43 (73%) |
| Recruitment maneuver first | 32 (54%) |
| Data are expressed as number (percentage) or mean±standard deviation for n=59. Hypertension is defined as systolic blood pressure between 140 mmHg and 180 mmHg and diastolic blood pressure between 90 mmHg and 110 mmHg. Severe stenosis of contralateral ICA is defined as stenosis of contralateral ICA greater than 70% diagnosed by preoperative digital subtraction angiography. Collateral circulation is defined as anterior or posterior branches open detected by preoperative transcranial color-coded duplex. ASA – American Society of Anesthesiologists; ICA – internal carotid artery. | |
