摘要
对主动脉弓支动脉粥样硬化性狭窄患者23例,锁骨下动脉狭窄患者20例,头臂干狭窄患者3例行血管内扩张术(RED)。扩张前患者狭窄区收缩压梯度为25 ~ 55 mm Hg,动脉管腔收缩40% ~ 80%。17例收缩压梯度完全消失,7例收缩压梯度维持在10 ~ 40 mm Hg。在左锁骨下动脉RED手术过程中,1例发生动脉远端急性血栓形成并发症。在积累经验的基础上,阐述了锁骨下动脉狭窄扩张的适应症。
[Debatable problems of intravascular dilatation of the brachiocephalic artery].
Roentgen--guided endovascular dilatation (RED) was conducted in 23 patients with atherosclerotic stenoses of branches of the arch of the aorta, in 20 with stenoses of the subclavian artery, and in 3 with stenoses of the brachiocephalic trunk. Before dilatation the patients had a systolic pressure gradient of 25 to 55 mm Hg in the region of the stenosis and constriction of the arterial lumen by 40 to 80%. Systolic pressure gradient disappeared completely in 17 cases and persisted at a level of 10 to 40 mm Hg in 7 cases. During RED of the left subclavian artery a complication, acute thrombosis of the distal part of the artery, occurred in one case. Indications for dilatation of stenosed subclavian arteries were elaborated on the basis of the accumulated experience.
