【摘要】 目的:探讨超声介入注射无水酒精治疗甲状腺结节的量化方法及疗效。方法:42例甲状腺结节患者在超声引导下行无水酒精注射治疗(percutaneous ethanol injection PEI),并计算酒精注射量与弥散范围最大径、肿块大小与酒精注射量的相关系数及回归方程。结果:(1)经6个月~1年的随访,治愈者32例(76.2%),有效者7例(16.7%),无效者3例(7.1%);(2)酒精注射量与弥散范围呈正相关(r=0.775,P<0.002),甲状腺结节大小与酒精注射量的回归方程为:Y=3.02X-0.9021(式中X为结节最大径cm,Y为酒精注射量mL)。结论:通过酒精注射量与弥散范围相关关系研究导出的甲状腺结节直径与酒精注射量的回归方程经临床应用与随访观察,疗效较好,可作为行PEI时酒精注射量的计算方法。更多还原

【Abstract】 Objective:To probe the method of percutaneous ethanol injection(PEI) in treatment of thyroid nodules.Methods: In 42 patients with autonomous thyroid nodules were treated by ultrasound guided PEI.The interrelated coefficience of the quantity of alcohol injection into the nodules and the diameters of spreading areas of the alcohol on the screen were measured.The regressive quantity of the diameters of the nodules and the quantity of alcohol were calculated.Results:(1)After three months to one year follow-up,32 cases(76.2%) were healed,7(76.2%) recovered,and 3(16.7%) no effect.(2)The quantity of alcohol and the alcohol spreading area was markedly positive interrelated(r=0.775,P<0.002).The regressive equation of the diameters of the nodules and the quantity of alcohol was Y=3.02X-0.9021(X was the alcohol diameter,the unit was cm.Y was the alcohol quantity,the unit was ml).Conclusion: Thyroid nodules are cured by PEI with the quantified alcohol calculated by the regressive quantity of the diameters of the nodules and the quantified alcohol inferred from the interrelationship between the quantity of alcohol and the diameter of spreading area of the alcohol.更多还原
