Open surgery has been gradually replaced by
endovascular surgery in recent decades in treating patients
with aortic pathology such as aneurysmal formation, aortic
dissection or rupture that are associated with high mortality
rates. As endovascular surgery has to be performed under Xray
fluoroscopy, it is unavoidable that surgeons will be exposed
to ionizing radiation. The aim of this study is to evaluate the
radiation dosages received by surgeons when performing these
operations. Simulation experiments have been carried out by
employing ATOM human prosthesis as patient and mannequin
as surgeon under realistic surgical conditions. Radiations
doses were recorded at locations of lenses, thyroid gland, chest
and limbs under exposure modes of fluoroscopy and DSA
(digital subtraction angiography). The effective doses received
by the cardiovascular surgeons during aortic stent implantations
were found to be 5.29 μSv or 5.62 μSv wearing protective
lead clothing and glasses which is safe under current legislations
of radiation protection. It is recommended that surgeons
should wear protective devices at all time during surgical
