Exoskeleton-supported protection versus lead apron during endovascular aortic repair

Radiation Exposure and Operator Musculoskeletal Strain in Endovascular Aortic Repair: a Randomized Trial of Exoskeleton vs. Standard Aprons

Not applicable Interventional Samodzielny Publiczny Szpital Kliniczny nr 2 PUM · NCT07528144

This study will test whether using an exoskeleton-supported radiation protection system can lower radiation exposure and reduce muscle strain for vascular surgeons doing complex endovascular aortic repairs.

What this trial studies

This is a prospective, randomized, controlled crossover trial conducted at the Department of Vascular Surgery, University Clinical Hospital No. 2 in Szczecin, Poland. Two experienced vascular surgeons will perform a total of 60 EVAR, BEVAR, and IBD-EVAR procedures, with each procedure randomly assigned to use either a standard lead apron or an exoskeleton-supported protection system with visor. Operator radiation exposure will be recorded in real time with personal dosimeters, and shoulder load will be measured with sensors; operators will also complete standardized fatigue and discomfort questionnaires after each case. No switching of protection systems will occur during individual procedures so that each intervention is completed under the assigned protection method.

Who should consider this trial

Good fit: Ideal participants are experienced vascular surgeons age 35 or older who regularly perform endovascular aortic repair procedures and can provide informed consent and safely use both standard lead aprons and the exoskeleton system.

Not a fit: Surgeons who do not perform complex endovascular aortic repairs, who cannot safely wear the exoskeleton or lead apron, or who have health contraindications to participation are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, the exoskeleton-supported system could meaningfully reduce surgeons' radiation exposure and musculoskeletal strain during complex fluoroscopic vascular procedures, improving occupational safety and comfort.

How similar studies have performed: Small feasibility studies of wearable exoskeletons in surgical and interventional settings have shown reduced musculoskeletal load and fatigue, but combining exoskeleton support with radiation-protective visors is relatively novel and has limited comparative data on radiation dose reduction.
