Calculation of Radiation Dose Received by Patients during Cardiac Interventional Procedure

The process of interventional procedure can be associated with multilevel of radiation doses, the current study intends to measure patient dose and estimate the radiation dose received for patient during interventional cardiology (IC) procedures. In order to match the acceptable level, A 206 patients underwent IC procedure and the radiation dose were measured in Khartoum state hospitals, Sudan, in four types of (IC) procedures which are (CA, PCI, PTMC and pacemaker) the number patients for each procedure was 145, 39, 4 and 18 respectively. The mean age of patients was 59.914.1 which ranged from 3 to 100 years. The mean value of tube parameter was 78.211.4KVp, (ranged from 50 to 109 Kvp), 7.1 0.72 mAs (ranged from 3 to 10.2 mAs). The mean time of fluoroscopy exposure that was used during these procedure was 6.97.1 mint. Dosimetric quantity, called KERMA Area Product (KAP), and uoroscopy time were registered during four selected procedures. For CA, PCI, PTMC and pacemaker the mean and median KAP values demonstrated as higher and lower values were found to be (63.69, 52 Gy. cm2) (18.78, 15.5 Gy. cm2) for PCI and pacemaker respectively. The higher mean and median uoroscopy time in minutes (11.43, 9.70) as registered for PCI procedure was reported in this study which may considered relatively higher value than reported in the literature.
