Most authors associate avascular necrosis of the femoral head with ischemia, caused by injuries or diseases of the nutrient vessels or by alteration of the hemorheology. We examined the rheological properties of the blood in 39 patients with nontraumatic avascular necrosis of the femoral head by following tests: viscosimetry, filtrometry and aggregation of red blood cells. Aggregation of red blood cells showed statistically significant pathologic alterations. Our results confirm that irreversible agglutination phenomenons followed by ischemia can be caused by 1. stenosis or obliteration of nutrient vessels 2. rheologic alterations of the blood.
大多数作者将股骨头缺血性坏死与缺血联系起来，这种缺血是由营养血管的损伤或疾病或血液流变学改变引起的。我们通过以下测试检查了39例非创伤性股骨头缺血性坏死患者的血液流变学特性：粘度测定、滤过测定和红细胞聚集。红细胞聚集显示出具有统计学意义的病理改变。我们的结果证实，由1. 营养血管狭窄或闭塞2. 血液流变学改变可导致不可逆的凝集现象继而引发缺血。
