Abstract
The intervention procedures are performed under fluoroscopic guidance and become increasingly common because of their obvious benefits to patients. Patient dose during cardiologic procedures is high due to lengthy procedure and the prolonged exposure time to the patient. Objective: The primary objective of the study was to evaluate the level of radiation dose received by the patients in order to estimate local diagnostic reference levels during cardiac catheterization procedures individually in terms of E (effective dose). Effective dose and doses to various organs estimated with the help of Monte Carlo PCXMC software.Material and Methods: A total of 123 patients were included in these studies, who were admitted to Cardiology department, and the data were collected retrospectively in a designed format during both diagnostic and therapeutic procedure.Results: The estimated patient dose rate as a whole in the Cath-Lab was found to be 96.45mGy/min which is considered lower than the recommended DRL (dose reference level) for the continuous high mode fluoroscopy used in interventional radiology (100mGy/min) given by IAEA. The effective dose was calculated and found respectively for CA-TFA, CA-TRA and CA-PTCA as 6.13mSv (range2.4-17.33), 10.97mSv (range 5.56-29.03) and 34.68mSv (range 10.64-70.21). We observed strong correlation between total duration of procedure (both fluoroscopy and cine time) with effective dose(R=0.95, p<0.00001) and a weak although statistically significant correlation between BMI (body mass index) with effective dose(R=0.526, p<0.00001) wasobserved. A significant increase of doses in TRA procedure in regard to TFA procedure was also noticed in our study.Conclusions: It is anticipated that this study is going to assist the institutions having Cath-Lab facilities of this region in encouraging the standardization of procedure, which may help increase awareness and aims to serve as guidance for Cardiologist.
