Abdominal aorta aneurysm : case report of high radiation dose during stent-graft implantation

This study is a case report regarding a possible problem of high radiation dose during stent-graft implantation. Before deciding on how to treat an aneurysm (stent grafting or traditional surgery), possible complications such as difficult anatomical conditions and diseases of the aorta and iliac arteries should be considered to avoid potentially high doses of radiation. In case of this patient, it was very difficult to introduce a guidewire through the contralateral limb into the body of the graft due to tortuosity and kinking of iliac arteries. Because of the long duration of the procedure (68 min), the patient was exposed to a very high radiation dose (4.37 Gy) and DAP (1760.3 Gy cm²).
