- W2318958002 abstract "Background: Some studies have reported higher patient radiation exposure with radial approach coronary angiography (CA) ± percutaneous coronary intervention (PCI). The United Nations Scientific Committee on Effects of Atomic Radiation recommends 7 mSv as an appropriate average effective dose (E) for routine CA. Therefore, we compared patient radiation exposure from radial v femoral approach during cardiac catheterisation. Methods: Consecutive patients (n = 168) over six mths in 2011, undergoing routine CA ± PCI at Royal Prince Alfred Hospital, Sydney by a single interventional cardiologist were identified. The two angiography suites employ Siemens Axiom Artis dFC (flat panel) and FC (image intensifier) equipment. Radiation doses were automatically recorded as dose area products at procedure time and converted into E using a conversion factor of 0.18 mSv/(Gy cm2), as validated by the National Radiological Protection Board (NRPB). Results: One hundred and eight patients underwent diagnostic CA (53 femoral, 55 radial); 60 underwent CA + PCI (26 femoral, 34 radial). For femoral CA E = 8.24 ± 7.14 mSv and for radial CA E = 8.76 ± 10.55 mSv. For femoral CA + PCI E = 14.91 ± 6.75 mSv and for radial CA + PCI E = 15.05 ± 10.82 mSv. There was no difference in radiation exposure between radial and femoral CA (p = 0.76) or CA + PCI (p = 0.95). Conclusion: At a high volume angiography laboratory, radiation doses for routine angiography were near UNSC targets. There was no difference in radiation exposure from radial or femoral approach. Radiation dose is higher in patients undergoing PCI as expected." @default.
