Radiation Dosage Analysis of Interventional Examination and Embolization in Vascular Malformation of Spinal Cord

WANG Jin long, LING Feng, LI Ya chun, et al (Department of Interventional Radiology Center, Xuanwu Hospital of Capital University of Medical Sciences, Beijing 100053, China) [  
s] 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. [
