Fusion Imaging Guidance Does Not Affect Radiation Exposure During Endovascular Procedures for Lower Extremity Arterial Disease: A Randomized Controlled Trial.

Radiation exposure for vascular interventionalists is still a concern. The aim of this study was to assess the value of advanced imaging guidance on radiation exposure and iodinated contrast volume during endovascular treatment of lower extremity arterial disease (LEAD). It was a prospective, randomized, monocentric, pilot, single-operator study, conducted from June 2018 to October 2019. Consecutive patients requiring a preoperative computed tomography angiography (CTA) for a symptomatic LEAD and scheduled for an iliac and/or femoropopliteal endovascular repair in a hybrid room were included. Patients were randomly assigned to the use of fusion imaging guidance (Vessel Navigator In all, 64 of the 77 patients enrolled (34 in fusion group, 30 in control group, 82% men, 65.8 years [61-71]) were included. Groups were similar in terms of comorbidities, BMI (26 kg/cm Fusion imaging guidance does not affect radiation exposure and contrast volume during endovascular revascularisation of iliac and femoropopliteal occlusive disease in a hybrid room environment.
