Case 1

根据术前造影显示胫前动脉、胫腓干、腓动脉及胫后动脉均可见残端,均可以尝试开通。而下段经侧枝显影的为胫后动脉和腓动脉可能开通更为容易


Btk

腓动脉导丝通过并扩张


Btk

胫后动脉导丝通过并扩张


Btk

PTA后

造影


Btk

Case 2

BTK病变,AT、PT均闭塞。

注意胫前动脉短小盲端


Btk

导丝试探通过ATA闭塞段成功


Btk

分别扩张胫前动脉及腓动脉


Btk

正位下足动脉弓呈α形


Btk

BTK 病变腔内治疗现状

  • 腔内开通闭塞血管病变器材发展迅猛

    • 专用导丝、球囊、专用支架

  • 腔内治疗开通闭塞病变技术逐渐成熟

  • 近期疗效满意?!

  • 长期疗效?

  • 近期再闭塞?!


Btk

POBA后再狭窄的主要原因

  • 血管弹性回缩:支架

  • 血管负面重塑:支架

  • 内膜增生:药物球囊


Btk

支架在BTK闭塞病变的应用效果?


Btk

均为冠脉支架,非专用支架


Btk

结 果


Btk

普通冠状动脉支架没有优势专用支架的研究如何?


Btk

药物洗脱支架与POBA

Summary

Summary

Angiologie

Herz-Zentrum Bad Krozingen

SES achieve significantly higher primary and secondary patency rates at 1 year as compared with BMS in the treatment of infrapopliteal lesions.

The improvement in Rutherford-Becker class at 1 year was significantly better in the SES group.

In the long run, the superior patency of SES may also improve limb salvage rates in patients with CLI Rutherford class 5 & 6 and an appropriate life expectancy.

小 结

  • BKT 病变,尤其长段病变POBA治疗后再狭窄临床的主要问题

  • 专用支架、药物洗脱支架的应用可降低再狭窄率。但使用位置受限

  • 药物球囊的初步临床研究,结果令人鼓舞
