■我们旨在评估使用新一代双平面血管造影系统减少辐射剂量的安全性和有效性。
■将50例接受经导管PDA封堵术的儿科患者随机分为正常剂量和低剂量两组。除PDA关闭外,需要其他手术的患者被排除在外。根据缺损的血管造影测量进行PDA闭合。手术后,年龄,体重,性别,PDA测量,和辐射测量,如剂量面积乘积(DAP,Gy.cm2)和空气角化(AK,mGy)进行组间比较。
■各组之间在年龄上没有统计学上的显着差异,性别,体重,PDA直径,PDA类型,使用的设备,和设备直径(p>0.05)。虽然在电影记录方面两组之间没有统计学上的显著差异,记录的图像数量,和透视时间(p>0.05),总DAP之间有统计学上的显著差异,电影和透视DAP,总AK,额管和侧管AK,和DAP/kg(mGy。m2/kg)测量值(p<0.05)。
■低辐射剂量的经导管PDA封堵与正常辐射剂量的封堵同样有效。患者在手术过程中接受的辐射剂量显着降低。根据这项研究提供的愿景,它似乎可以在其他组患者中使用低辐射剂量。
UNASSIGNED: We aimed to evaluate the safety and efficacy of radiation dose reduction with a new-generation biplane angiocardiography system in patients undergoing transcatheter isolated patent ductus arteriosus (PDA) closure.
UNASSIGNED: Fifty pediatric patients who underwent transcatheter PDA closure were randomly divided into two groups as normal radiation dose and low dose. Patients who required additional procedures other than PDA closure were excluded. PDA closure was performed according to the angiographic measurement of the defect. After the procedure, age, weight, sex, PDA measurements, and radiation measurements such as dose-area product (DAP, Gy.cm2) and air kerma (AK, mGy) were compared between the groups.
UNASSIGNED: There was no statistically significant difference between the groups in age, sex, weight, PDA diameter, PDA type, device used, and device diameter (p > 0.05). While there was no statistically significant difference between the groups in terms of cine recording, number of recorded images, and fluoroscopy time (p > 0.05), there was a statistically significant difference between the total DAP, cine and fluoroscopy DAP, total AK, frontal and lateral tube AK, and DAP/kg (mGy.m2/kg) measurements (p < 0.05).
UNASSIGNED: Transcatheter PDA closure with a low radiation dose is as effective as that with a normal radiation dose. The radiation dose received by the patient during the procedure was significantly reduced. With the vision provided by this
study, it seems possible to work with a low radiation dose in other groups of patients.
