| Abstract:: |
| Objective To collect and analyze the radiation dose to patients in cardiovascular interventional procedures and the radiation dose-related indicators, in order to provide a basis for improving radiation protection of patients. Methods The clinical data of 26 cases of complete cardiovascular interventional procedures was collected in the municipal Grade A Class Three hospitals, including coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA), and the patient-received radiation doses and other related factors was studied. TLD personal dosimeter radiation field matrix method was used to measure fluorescence time, the entrance skin dose (ESD), the peak skin dose (PSD), dose-area product (DAP) and other indicators. TLD was used to measure the organ dose of the phantom under the cardiovascular interventional procedure condition. Results The fluoroscopy time was (17.7?15.6) min during the range of 0.80-42.4 min. The average entrance skin dose (ESD) was (159?138)mGy during the range of 4.40-459 mGy. The peak skin dose (PSD) was (769?705)mGy during the range of 22.6-2.43?103 mGy. The fluorescence time, entrance skin dose (ESD),peak skin dose (PSD) of the group CA PTCA are greater than the group CA and the difference has statistical significan. The peak skin dose and the fluoroscopy time have good linear correlation (r=0.84,P<0.01). Conclusion The peak skin dose the patient received in cardiovascular interventional radiological operation can be estimated through the fluoroscopy time. |
