摘要
目的探讨对吻球囊技术和对吻支架技术治疗肾动脉狭窄分叉病变的疗效。方法共5例患者采用对吻球囊技术或对吻支架技术治疗粥样硬化性肾动脉狭窄分叉病变。结果 5例患者肾动脉主支参考血管直径(RVD)为(5.6±0.4)mm,分支1RVD为(3.4±0.4)mm,分支2RVD为(3.6±0.5)mm。3例患者采用对吻球囊技术治疗肾动脉分叉病变,并于主支-分支置入支架,均有不同程度的残余狭窄;2例患者采用对吻支架技术治疗肾动脉分叉病变,无残余狭窄。术后随访2例患者血压水平降低,3例患者血压水平无明显变化,其中1例血压水平虽无明显变化,但服用的降压药物种类减少。1例患者术后血肌酐水平显著降低。结论对吻支架技术适用于分叉近端主支血管内径明显大于分叉远端分支血管内径的情况。从有限的经验来看,似乎对吻支架技术与对吻球囊技术相比具有更好的即刻影像学效果。
Objective To investigate the efficacy of kissing stent or kissing balloon technique for renal artery bifurcation with atherosclerotic renal artery stenosis （ARAS）. Methods Five patients with ARAS involving renal artery bifurcation were included and the kissing technique was applied. Results The reference vascular diameter （RVD） of main renal artery was 5.6±0.4 mm. The RVD of renal artery distal to bifurcation were 3.4±0.4 mm and 3.6±0.5 mm. Kissing ballon technique was used in three patients with obvious residual stenosis,and kissing stent technique was used in two patients without obvious residual stenosis. Blood pressure was lowered in two patients,but unchanged in three patients. Serum creatinine was lowered in one patient. Conclusion As for angiographic residual stenosis,kissing stent technique appears to be more efficacious than kissing balloon technique.
