摘　　要：目的:探讨动脉粥样硬化(AS)斑块的血管内超声消融价值。方法:30例冠状动脉AS患者被前瞻性随机分为血管内超声消融组(A组,15例)和单纯PTCA组(B组,15例)。回顾性分析前述两组及9例经血管内超声消融的外周AS患者的疗效。结果:A组经单纯冠脉内超声消融治疗后狭窄程度由(84.1±4.7)％降为(43.0±15.5)％(P<0.05),无1例并发症,但其残余狭窄(43.0±15.5)％仍显著高于B组(P<0.01),B组在PTCA术后残余狭窄为20.9±2.9％。9例外周AS者经单纯血管内超声消融后,平均狭窄程度也由术前的(87.8±7.6)％降为(41.2±9.4)％(P<0.05)。结论:血管内低频高能超声消融术是动脉粥样硬化斑块的一种新的、有效治疗手段。Objective: To explore the therapeutic efficacy for ultrasound ablation of atherosclerotic plaques. Methods: Thirty patients with atherosclerotic (AS) plaques of coronary artery were divided into ultrasonic dissolved group (group A, 15 cases) and PTC A group (group B, 15 cases) randomly. The data of two group above stated and nine cases of the peripheral arterial AS were analyzed retrospectively. Results: The coronary artery stenosis of group A decreased from (84. 1±4. 7)% before ultrasonic ablation to (43. 0±15. 5)% after ultrasonic ablation (P<0. 05), without any complication. The residual stenosis was more severe in the group A compared with that of group B (43- 0 ± 15. 5% > 20. 9±2. 9%, P<0. 01). The peripheral arterial stenosis also decreased from (87. 8±7. 6)% before the ultrasonic ablation treatment to (41. 2±9. 7)% after ultrasonic ablation ( P<0. 05). Conclusion: Angioplasty with high intensity? low frequency ultrasound can be used as a new and effective approach for the atherosclerotic stenosis therapy.
