| 目的 测量在脊髓血管畸形的介入放射学检查及治疗过程中患者及介入医生所受到的X线辐射剂量;分析影响X线辐射剂量的因素及其减低剂量的途径和方法。方法 应用热释光测量法对我中心近期100例脊髓血管畸形进行介入放射学检查和(或)介入治疗辐射剂量测量。 结果 全脊髓血管造影患者皮肤剂量范围0.009~2.032Gy,介入医生所受剂量范围 0.225~1.601mGy;进行栓塞治疗时患者皮肤剂量范围2.131~9.874Gy,介入医生所受剂量范围0.307~2.462mGy。结论 全脊髓血管造影是诊断脊髓血管畸形的金标准,并为手术或介入治疗提供重要依据。介入栓塞治疗是治疗脊髓血管畸形的重要而有效的方法之一,但是患者及介入医生所受的X线辐射剂量很大,个别患者可出现急性放射性皮肤红斑、脱发等症状。因此应该采取有效的防护措施来减低X线辐射剂量。 |

| Objective To investigate the X-ray radiation dosage of patients and physicians in the interventional examination and embolization in vascular malformation of spinal cord, and to analysis the factors which influence X-ray radiation dosage as well as the ways to decrease the dosage. Methods Thermoluminescence was used to measure the X-ray radiation dosage of patients and physicians in the interventional examination and embolization in vascular malformation of spinal cord with 100 cases in our department from March in 1998 to January in 2003. Results The dosage of skin in the patients who accepted spinal angiography was 0.009-2.032Gy; While the dosage of skin in the physicians was 0.225-1.601mGy. The dosage of skin in the patients who accepted interventional embolization was 2.131-9.874Gy; While the dosage of skin in the physicians was 0.307-2.462mGy. Even some of them appeared acute radiate erythema or alopecia. Conclusion Spinal angiography provide a great quantity of information for both diagnosis and treatment of vascular malformation of spinal cord. Meanwhile, interventional embolization is now regarded as an important therapeutic method for spinal cord vascular malformation. However, both the patients and physicians exposed to too much X-ray radiation during interventional procedures. Some more effective protection should be taken to decrease the X-ray radiation dosage accepted by patients and physicians. |
