早在1936年以前报告中提示过肝素可以预防脑血栓形成,直到1936年才有人在动物实验中证实有效。到1944年Olovson外科医生用小量肝素预防术后血栓及栓塞,但没有提供材料。到1966年有人开始用肝素预防手术前、中、后血栓形成及栓塞。直到1970年以后才开始对静脉血栓及手术前后预防血栓引起新的兴趣。对于治疗脑动脉硬化血栓形成只有提示而无报告材料。我院自1979年2月至1980年6月共 As early as 1936 before the report suggested that heparin can prevent cerebral thrombosis, and only in 1936 was confirmed in animal experiments. By 1944 Olovson surgeons used small amounts of heparin to prevent postoperative thrombosis and embolism but did not provide the material.
