《冠狀動脈造影ab》

冠心病介入診療--ABC整理課件1929年,德國醫(yī)生WennerForssmann在自己身上進(jìn)行了人類首例心導(dǎo)管檢查術(shù).他將導(dǎo)管經(jīng)左肘前靜脈,鎖骨下靜脈,上腔靜脈送入右心房,并拍了醫(yī)學(xué)史上第一張右心導(dǎo)管胸片,從此揭開了介入心臟病學(xué)的序幕.整理課件1959年MasonSones

利用特制的尖端呈弧形的造影導(dǎo)管,經(jīng)肱動脈送入主動脈根部進(jìn)行主動脈造影,無意中將造影劑直接注入右冠狀動脈內(nèi)使其清晰顯影,這一偶然事件開創(chuàng)了冠脈介入診斷技術(shù)的新紀(jì)元整理課件冠脈造影50余年的歷程!CAintroducedbyF.MasonSones,Jr,MD(首次冠脈造影)
