Abstract

OBJECTIVE

To use intravascular ultrasound in vivo to evaluate changes in the intimal thickness of angiographically normal saphenous vein grafts one year after implantation.

DESIGN

Fifteen saphenous vein grafts in 12 patients were examined one month and 12 months after aortocoronary bypass graft surgery with intravascular ultrasound using a 30 MHz transducer. None of the grafts examined showed any angiographic abnormalities. The intimal thickness and intimal area of the graft in the proximal portion were measured on intravascular ultrasound images obtained one month and 12 months after operation.

SETTING

General hospital.

PATIENTS

Twelve patients who underwent aortocoronary bypass graft surgery.

RESULTS

The ultrasound images showed a thin-walled graft with a thin intima one month after operation (mean (SD)) (0.31 (0.09) mm). The intimal thickness of the graft increased significantly to 0.65 (0.08) mm (P < 0.001) 12 months after operation. The intimal area of the graft was 0.90 (0.80) mm2 one month after operation. 12 months after operation the intimal area had increased significantly to 5.26 (1.38) mm2 (P < 0.001).

CONCLUSION

Intravascular ultrasound in vivo showed that one year after implantation angiographically normal saphenous vein grafts had a thicker intima than one month after implantation.

摘要

目的

运用血管内超声在体内评估冠状动脉搭桥术后一年造影显示正常的大隐静脉移植血管内膜厚度的变化。

设计

对12例患者的15条大隐静脉移植血管在主动脉冠状动脉搭桥术后1个月和12个月时，使用30MHz探头进行血管内超声检查。所有检查的移植血管造影均无异常。在术后1个月和12个月获取的血管内超声图像上测量移植血管近端的内膜厚度和内膜面积。

地点

综合医院。

患者

12例行主动脉冠状动脉搭桥术的患者。

结果

超声图像显示术后1个月移植血管壁薄，内膜薄（均值（标准差））（0.31（0.09）mm）。术后12个月移植血管内膜厚度显著增加至0.65（0.08）mm（P<0.001）。术后1个月移植血管内膜面积为0.90（0.80）mm²。术后12个月内膜面积显著增加至5.26（1.38）mm²（P<0.001）。

结论

血管内超声在体内显示，移植术后一年造影显示正常的大隐静脉移植血管内膜比术后1个月时更厚。
