急診PCI的特殊問題罪犯血管的罪犯病變和非罪犯病變(課堂PPT)

1、1,急診PCI的特殊問題罪犯血管的罪犯病變和非罪犯病變,信栓力 博士 主任醫(yī)師http:/ ,2,Case baseline data,MV-PCI:罪犯血管和非罪犯血管因支施救：除非有血流動力學(xué)紊亂并且非罪犯病變狹窄大于90%時，一般只處理罪犯病變。 韓雅玲教授的觀點：在有缺血證據(jù)的前提下，在同次住院期內(nèi)處理非罪犯血管。,3,關(guān)注支中重點：罪犯血管的罪犯病變和非罪犯病變：tandem病變、多處病變 急性心肌梗塞時血管容易痙攣、機體處于高凝狀態(tài) Tandem病變或彌漫性長病變一個支架不能完全覆蓋時，怎么辦？一個和多個支架植入對預(yù)后的影響是什么？瑞金醫(yī)院張奇做了初步研究

2、。,4,當(dāng)罪犯血管存在tandem病變或彌漫性長病變時，如果一個支架不能完全覆蓋，建議只處理罪犯病變。 且看我院的三個病例,5,Our hospital case01,Overall views of this puzzle patient,6,image01,Emergency PCI Indicates a ostial total occlusion of LAD-2012.3.26,7,The patients RCA,8,Initial dilation of the culprit lesion,9,Shows the result post initial dilation,10
