Patient radiation exposure during percutaneous endovascular revascularization of the lower extremity

Abstract

Percutaneous endovascular revascularization for lower extremity peripheral artery disease involves a substantial radiation dose, comparable, on average, to a computed tomography scan of the abdomen and pelvis. Procedures performed in the pelvis for intermittent claudication involve more radiation than thigh or below-knee procedures for chronic critical limb ischemia. Radiation dose should be considered when planning these procedures.

Preclinical study testing feasibility and technical requirements for successful telerobotic long distance peripheral vascular intervention

“…Similar fluoroscopy time (7.1 ± 3.2 min) and contrast dose (73.3 ± 9.2 ml) were shown in the RAPID trial, 4 where femoropopliteal lesions were treated with robotic assistance. Fluoroscopy times for the conventional manual treatment of femoropopliteal lesions are reported to be between 7.4 and 16.4 min 13–15 . For the manual treatment of TASCII A superficial femoral lesions, Majewska et al 13 .…”

Using 7.5 frames per second reduces radiation exposure in lower extremity peripheral vascular interventions

“…DAP has been reported to be significantly higher for procedures performed in the pelvis compared to limb procedures. 15 In our study, there was benefit of using 7.5 fps in both pelvic and limb locations. To the best of our knowledge, this is the first study to compare the radiation exposure associated with 7.5 fps use as opposed to conventional 15 fps in PVIs.…”

“…Because of the difference in pelvic and limb location of lesions, we did subanalysis comparing radiation dose in pelvic location and limb location within groups A and B. In the pelvic location: Mean DAP was still significantly lower in 7.5 fps compared to 15 1 and 2. Figure 3 is shows the cine angiogram of superficial femoral artery obtained with 7.5 frame rate.…”

Three cases of fusion imaging in endovascular treatment of occlusive peripheral artery disease

“…The mean procedural iodinated contrast agent dose and fluoroscopy time of the three cases were 60 mL and 28 minutes, respectively. The contrast agent dose and fluoroscopy time in patients undergoing similar ET procedures without using fusion imaging guidance are reported as 127 to 246 mL and 16 to 21 minutes, respectively 8, 9, 10. Our three cases were all occlusive femoral-popliteal lesions, which might have influenced the amount of fluoroscopy time.…”
