| 目的 通过对腹部不同介入治疗过程中患者所受辐射剂量大小的分析,探讨影响辐射剂量的主要因素。 方法 对156例接受腹部介入操作患者的临床和技术资料进行回顾性分析,按手术类别分为8组,记录每组患者在操作过程中所受透视、摄影剂量面积乘积值和透视时间,并对各组结果进行统计学的描述性分析。 结果 8组的透视和摄影DAP值范围分别为10.9~398.0 Gycm2、10.8~865.3 Gycm2, 透视时间范围是1.9~55.6 min。肝癌栓塞化疗、肾动脉支架、肾癌栓塞组、肝血管瘤栓塞、子宫栓塞化疗、脾动脉栓塞组的DAP(dose-area product, DAP)值(77.3~217.7 Gycm2)较高;肝癌栓塞化疗、肾动脉支架、肾癌栓塞、肝血管瘤栓塞、PTBD组透视时间(12.7~18.6 min)较长。 结论 不同类别腹部介入操作,患者所受辐射剂量差异较大。介入操作过程中,应采用合理措施,在达到预期诊断和治疗的前提下,使患者所受辐射剂量合理降低。 |

| Objective To analysis the patients doses and the influential factors during abdomen therapeutic interventional procedures carried out in a dedicated angiographic unit. Methods One hundred and fifty-six patients were enrolled in our study. Eight groups were classified according to the technique type (group 1: transcatheter hepatic arterial chemoembolization group 46 cases; group 2: renal arterial stenting 25 cases; group 3: renal carcinoma embolization 21 cases; group 4: hepatic hemangiomas embolization 19 cases; group 5: uterine arterial chemoembolization 13 cases; group 6: bladder carcinoma chemotherapy 12 cases; group 7: percutaneous transhepatic biliary drainage 11 cases; group 8: splenic arterial emboliziation 9 cases). The dose-area product (DAP) of fluoroscopy and expoure, and fluoroscopy time were recorded. For each category, descriptive statistical analysis was used to determine the characteristics of DAP and fluoroscopy time distributions. Results For the 8 categories studied, the median DAP values ranged from 11.3 to 398.0 Gycm2 (fluoroscopy), and 10.8 to 865.3 Gycm2 (exposure). Fluoroscopy time ranged from 1.9 to 55.6 minutes. DAP values were greater for 6 groups (1, 2, 3, 4, 5, 8), fluproscopy time were longer for 5 groups (1, 2, 3, 4, 7). Conclusion The difference of patients doses were greater during abdomen therapeutic interventional procedures. It is necessary to optimize radiation dose by adopting dose reduction techniques so as to maintain radiation dose as low as reasonably achievable with adequate image quality. |
