Abstract:
Objective To evaluate the feasibility and safety of stent implantation in treating patients with symptomatic vertebral artery kinking.Methods Thirty-six patients with vertebral artery kinking confirmed by DSA and accorded with the stent implantation indications were chosen in our study;these patients were performed stent implantation.The stenosis and haemodynamics changes,and recent and postoperative complications were observed; Malek scale was adopted to evaluate the clinical efficacy during the 1-year follow-up.Results The success rate of stent implantation for patients with symptomatic vertebral artery kinking was 100％.The percentage of stenosis was significantly reduced from(76％±15％)to(8％±3％)after stenting(P＜0.05); the mean flow velocity of kinking lesion was obviously decreased from([45.4±22.3]cr/s)to([31.8±15.1]em/s,P＜0.05); cerebellum hematoma was noted in 1 patient subcutaneous hematoma of puncture point in 2 and femoral artery pseudoaneurysms after the stenting in 1; all these complications did not cause serious consequences.Malek scale indicated that 31 patients got 1 point,3 got 2 points,1 got 3 points,1 got 4 points and no one got 5 points; 31patients were asymptomatic during the 1-year follow-up; no significant in-stent restenosis was found.Conclusion Symptomatic vertebral artery kinking can be treated safely and effectively with stent implantation.
