目的：探讨蛛网膜下腔出血（SAH）及其并发血管痉挛（CVS）的血液流交学变化。方法：对单纯S／＼H及并发CVS者作血液流变学检测。结果：单纯SAH的血液流变学无明显异常；CVS者在发生前有s项指标异常增高（P＜0．05或P＜0．01）；CVS发生后9项指标均明显增高（P＜0．05或P＜0．01）。结论；单纯SAH发生后血液流变学无明显异常，仅继发局部脑血管痉挛者出现明显血液流变学异常·并且这种变化可能与局部脑缺血症状的出现有关。
Objective: To investigate the changes of blood flow in subarachnoid hemorrhage (SAH) and its associated vasospasm (CVS). Methods: Hemodynamic tests were performed on patients with simple S / H and concurrent CVS. Results: The hemorheology of simple SAH had no obvious abnormality; the indexes of s items in CVS were abnormally increased before and after CVS (P <0.05 or P <0.01); all the 9 indexes of CVS were significantly increased (P < 0.05 or P <0.01). Conclusions: There is no obvious abnormality of hemorrheology after simple SAH, and obvious hemorrheological abnormality only occurs in patients with secondary cerebral vasospasm. And this change may be related to the appearance of local cerebral ischemia.
