目的 研究188Re液体充盈球囊导管对兔血管再狭窄模型用不同剂量内照射后对增生内膜不同的剂量效应。方法 16只新西兰白兔分成2组,一侧下肢髂动脉行内膜剥脱术后,通过直径2 .5mm液体188Re充盈球囊导管分别给以0 .8和15Gy剂量的血管内照射治疗。其中8只兔的另一侧髂动脉仅行内
Objective To study the different dosage effects of 188Re liquid-filled balloon catheter on proliferative intima with different doses of irradiation in rabbit model of vascular restenosis. Methods Sixteen New Zealand white rabbits were divided into two groups. One side of the iliac arteries of the lower extremities was treated by endovascular dissection with 188Re-filled balloon catheters with a diameter of 2.5mm. Of the eight rabbits, the iliac arteries were only in-line
