对比体外预开窗与原位开窗胸主动脉腔内修复术治疗主动脉疾病辐射剂量

Comparison on radiation doses of in vitro pre-fenestration and in situ fenestration thoracic endovascular aortic repair in treatment of aortic disease

目的对比体外预开窗与原位开窗胸主动脉腔内修复术(TEVAR)治疗主动脉疾病辐射剂量。方法回顾性分析51例接受体外预开窗(A组)及21例原位开窗(B组)TEVAR治疗的主动脉疾病患者,比较组间透视时间、总参考空气比释动能(AK)、总剂量面积乘积(DAP)及TEVAR治疗时间。结果对72例均顺利完成TEVAR。A组透视时间[(21.42±8.04)min vs.(34.57±9.07)min]及总DAP[44315.0(31157.0,56307.5)μGy·m^(2)vs.72153.0(45460.0,82354.0)μGy·m^(2)]均低于B组(P均<0.05),而总AK[2423(1638,3533)mGy vs.3600(1898,3921)mGy]及TEVAR用时[(83.41±22.89)min vs.(81.00±22.13)min]与B组差异均无统计学意义(P均>0.05)。结论相比原位开窗TEVAR,体外预开窗TEVAR治疗主动脉疾病所需透视时间及总DAP均显著降低。

Objective To compare the radiation dose of in vitro pre-fenestration and in situ fenestration thoracic endovascular aortic repair(TEVAR)in treatment of aortic disease.Methods Data of 51 patients with aortic diseases who received in vitro pre-fenestration(group A)and 21 cases who underwent in situ fenestration(group B)TEVAR were retrospectively analyzed.The fluoroscopy duration,total reference air kerma(AK),total dose area product(DAP)and TEVAR time were compared between groups.Results TEVAR was successfully completed in all 72 patients.Fluoroscopy duration([21.42±8.04]min vs.[34.57±9.07]min)and total DAP(44315.0[31157.0,56307.5]μGy•m^(2)vs.72153.0[45460.0,82354.0]μGy•m^(2))in group A were both significantly lower than those in group B(both P<0.05),while total AK(2423[1638,3533]mGy vs.3600[1898,3921]mGy)and TEVAR time([83.41±22.89]min vs.[81.00±22.13]min)in group A were not significant different from those in group B(both P>0.05).Conclusion Compared with in situ fenestration TEVAR,both the fluoroscopy time and total DAP of in vitro prefenestration TEVAR significantly reduced for treating aortic diseases.
