Patterns of procedure-specific radiation exposure in the endovascular era: Impetus for further innovation

Abstract

The increasing complexity of endovascular interventions has resulted in increased radiation exposure to all involved, with the highest doses occurring in aneurysm repairs. Future innovations should concentrate on reducing the risk of radiation exposure to all personnel and developing newer imaging techniques.

The impact of radiation dose exposure during endovascular aneurysm repair on patient safety

“…This alternative follow-up option may be especially relevant in younger patients to reduce the longterm carcinogenic risks of radiation exposure but is less pertinent for older patients because of the recognized latency period. 28 The protocol of our unit is under review to commence utilization of duplex imaging and AXR as the sole follow-up rather than annual CT scans.…”

Radiation exposure in endovascular procedures

“…1 To further reduce the radiation risks, the surgeon can employ higher kilovolt and lower milliampere settings and implement anti-scatter grids. 6 Pulsed fluoroscopy at "15 or 7.5 pulses per second decreases the fluoroscopy dose . .…”

Patient radiation exposure during percutaneous endovascular revascularization of the lower extremity

“…However, radiation dose in purely diagnostic procedures is lower than when an intervention is performed. 12,14,15,17,[19][20][21][22][23][27][28][29] Our results can be viewed in the context of radiation doses associated with other imaging studies patients commonly undergo. The mean DAP value obtained in this study for interventional pelvic procedures (179.6 Gy*cm 2 ) was higher than the patient mean DAP reported Percentages for patient and procedure characteristics were calculated from the total number of available data for any respective dataset.…”

“…11 Also, radiation exposure during lower extremity endovascular interventions have been reported. [12][13][14][15][16][17][18][19][20][21][22][23][24] Factors found to be associated with radiation in these procedures included operator skill, the equipment being used and patient clinical characteristics. 7 Radiation dose has not been reported in relation to lesion distribution or to specific procedure characteristics.…”
