The recently developed Grüntzig balloon dilatation catheter has facilitated the performance of transluminal angioplasty. The authors used this catheter in 35 arteries supplying the lower extremities in 27 patients. Immediate relief of symptoms (claudication and rest pain) occurred in 30 vessels (86%) in 23 patients. The procedure was well tolerated by all patients. Over 90% of initially successful dilatations were patent at 3 to 10 months.
最近研发的格鲁恩齐格球囊扩张导管推动了腔内血管成形术的实施。作者将此导管用于27例患者的35条下肢供血动脉。23例患者的30条血管（86%）症状（间歇性跛行和静息痛）立即得到缓解。所有患者对该操作耐受性良好。超过90%最初成功扩张的血管在3至10个月时仍保持通畅。
