1、DSA冠狀動(dòng)脈造影在冠狀動(dòng)脈病變?cè)\斷中的價(jià)值作者：肖榜喜 鐘燕青 鄭湞湞【關(guān)鍵詞】冠狀動(dòng)脈 摘要：目的:分析86例冠狀動(dòng)脈造影（CAG）的診斷結(jié)果，評(píng)價(jià)DSA―CAG對(duì)冠狀動(dòng)脈病變的診斷價(jià)值。方法：應(yīng)用DSA選擇性CAG證實(shí)病變≥50%直徑狹窄病例63例，依病變狹窄程度累及冠狀動(dòng)脈部位、數(shù)目、形態(tài)、冠狀動(dòng)脈優(yōu)勢(shì)狀況、側(cè)支循環(huán)及心肌梗死病例、左室壁運(yùn)動(dòng)情況和射血分?jǐn)?shù)（EF）等進(jìn)行統(tǒng)計(jì)分析。結(jié)果：50%狹窄或閉塞63例（73%）冠狀動(dòng)脈右優(yōu)勢(shì)型41例（66%），左優(yōu)勢(shì)型7例（11%）均衡型12例（20%），單支病變22例（36%）雙支病變17例（27%），3支病變20例（32%）受累血管104
2、支136處，重度狹窄及閉塞28處（45%），12例（19%）有不同程度側(cè)支循環(huán)形成，32例做了左心室造影射血分?jǐn)?shù)（LVEF）及室壁運(yùn)動(dòng)縮率分析，EF≥50%的20例（66%），EF40%~50%的7例（22%），＜40%2例（7%），經(jīng)統(tǒng)計(jì)學(xué)分析，嚴(yán)重冠狀動(dòng)脈狹窄與閉塞合并室壁瘤者與單純狹窄病變LVEF差異有極顯著意義（P＜0.01）。結(jié)論：冠狀動(dòng)脈循環(huán)與分布多數(shù)為右優(yōu)勢(shì)型，冠狀動(dòng)脈病變多累及前降支（LAD），其次為右冠狀動(dòng)脈（RCA）及左回旋支（LCF），病變程度多為嚴(yán)重狹窄，側(cè)支循環(huán)形成良好者對(duì)左心室功能有保護(hù)作用，高質(zhì)量的DSA設(shè)備是開(kāi)展冠心病介入的重要基礎(chǔ),DSA-CAG對(duì)冠狀脈病變
