本研究的目的是用放射光致发光玻璃剂量计测量脑动脉瘤患者的峰值皮肤剂量(PSD)和双侧晶状体剂量，并确定影响管道栓塞器(PEDS)治疗的辐射剂量的因素。累积剂量、PSD和左右晶状体剂量分别为3818.1±1604.6、1880.0±723.0、124.8±49.2和180.7±124.8 mGy.多因素分析显示，体重指数(P<；0.0 1；优势比(OR)=0.1.806；95%可信区间(CI)=0.1.007~3.238)和PED部署时间(P<；0.0 5；OR=0.1.107；95%CI=0.1.001~1.224)是PSD超过2GyPSD的独立预测因素。应采取准直照射野、优化照射剂量等措施，以减少对患者的辐射。
The purpose of this study was to measure the peak skin dose (PSD) and bilateral lens doses using radiophotoluminescence glass dosimeters and to determine the factors influencing the radiation dose in cases of cerebral aneurysm treated with pipeline embolization devices (PEDs). The cumulative dose, PSD and right and left lens doses were 3818.1 ± 1604.6, 1880.0 ± 723.0, 124.8 ± 49.2 and 180.7 ± 124.8 mGy, respectively. Using multivariate analysis, body mass index (p< 0.01; odds ratio (OR) = 1.806; 95% confidence interval (CI) = 1.007–3.238) and deployment time of PED (p< 0.05; OR = 1.107; 95% CI = 1.001–1.224) were found to be the independent predictors of PSD exceeding 2 Gy. Measures such as collimation of the radiation field and optimization of radiation dose should be taken to reduce the radiation to the patient.
