长期以来 ,普遍认为内膜增生和 /或血栓形成在介入性治疗后再狭窄的发生中具有重要意义。但是 ,虽然对内膜增生的机制进行了深入细致的研究 ,进行了各种动物实验和临床试验。到目前为止 ,已有 10 0多种企图通过干预内膜增生而达到防治再狭窄目的的实验研究获得专利 ,但却没有一 It has long been recognized that intimal hyperplasia and / or thrombus formation is of great importance in the development of restenosis after interventional therapy. However, a variety of animal experiments and clinical trials have been conducted, although intensively studying the mechanism of intimal hyperplasia. To date, more than 100 experimental studies attempting to prevent restenosis through interventional intimal hyperplasia have been patented, but none
