This section of coronary artery demonstrates remote thrombosis with recanalization to leave only two small, narrow chann图示：冠状动脉血栓形成后再通。可以看到两个狭窄的通道。
Results:In 0 patients, 79 oviducts were confirmed by hystero salpingography to be occluded. Of which 7 were succes果 : 0 例中经子宫输卵管造影共发现 79支输卵管不通 ,共疏通 7 支 ,总疏通率 9 . %。
Spontaneous recanalization was observed in 7.7% in cypher DES, .% in taxus stent group and 7.07% in BMS.闭塞的分支大部分会自行再通,在cypher组是7.7%,taxus组为 .%,BMS为7.07%,三组支架组间没有明显差异;
