The purpose of this study was to evaluate the use of intravascular sonography for the detection of arteriosclerosis and to determine the effects of vascular interventional procedures on the arterial wall. A catheter-based 20-MHz transducer was used. Forty patients were studied. Twelve had clinical evidence of peripheral vascular disease, 13 were healthy renal donors, and 15 underwent vascular interventional procedures. The aorta and the ipsilateral iliac artery were examined in real time under fluoroscopic guidance and the results were compared with angiography. Sonography in eight of the 13 renal donors showed arterial wall abnormalities in the absence of angiographic evidence of disease. Sonography of the 15 patients after angioplasty or atherectomy demonstrated plaque fractures, intramural dissections, or atherectomy grooves. Our experience suggests that intravascular sonography is of value in reducing the use of angiography to monitor progress or complications of vascular interventional procedures.
本研究的目的是评估血管内超声在检测动脉硬化中的应用，并确定血管介入手术对动脉壁的影响。使用了基于导管的20兆赫换能器。对40名患者进行了研究。12名患者有外周血管疾病的临床证据，13名是健康的肾供体，15名接受了血管介入手术。在荧光透视引导下实时检查主动脉和同侧髂动脉，并将结果与血管造影进行比较。13名肾供体中的8名超声检查显示动脉壁异常，但血管造影无疾病证据。15名接受血管成形术或斑块旋切术后患者的超声检查显示有斑块破裂、壁内剥离或斑块旋切沟。我们的经验表明，血管内超声在减少血管造影用于监测血管介入手术进展或并发症方面具有价值。
