摘要
目的在冠状动脉内注入声学造影剂Albunex,以评价其对血管内超声的影响。方法对23例经皮冠状动脉腔内成形术(PTCA)术后的患者,选择血管内超声(IVUS)检查,并通过导管将Al-bunex2ml以1ml/s的速度注入冠状动脉内,以测量注入前后的血管腔截面积和发现夹层。结果本组23例经PTCA后的患者在注入Albunex前,由两名独立观察者分别测量的血管腔截面积为(6.6±2.3)mm2和(7.6±2.1)mm2(r=0.53,P<0.05),冠状动脉夹层仅发现3例(3/23例)。注入后,两者的测量值分别为(8.8±3.4)mm2和(8.9±3.3)mm2(r=0.93,P<0.001),发现冠状动脉夹层7例(7/23例)。结论血管内超声和冠脉内注入Albunex的联合应用。
Objective\ To evaluate the effects of echocardiographic contrast following intracoronary Albunex injection on intravascular ultrasound (IVUS). Methods\ The 23 patients undergoing PTCA were examined by IVUS. Albunex was injected into coronary artery through catheter. The lumen ares was measured and coronary dissections were detectd. Results\ Before intracoronary Albunex injection, the mean cross section lumen area in 23 patients measured by two observers showed (6.6±2.3) and (7.6±2.1)mm 2 (r=0.53, P<0.05) respectively, coronary dissections were only found in 3 patients by IVUS. After the injections, the lumen area showed (8.8±3.4) and (8.9±3.3)mm 2 (r=0.93, P<0.001), the dissections were found in 7 patients. Conclusions\ IVUS combinated with intracoronary Albunex injection inhenced accuracy of qualitative and qantitative information on the lumen and plaque.
