This systematic review and meta-analysis evaluated peak skin dose (PSD) determination methods during endovascular aortic aneurysm repair (EVAR) procedures. Analyzing 11 articles with 19 cohorts, it found that indirect methods reported significantly higher PSD (3,115 mGy) compared to direct methods (558 mGy; P < 0.001). No significant difference in PSD was noted between standard and complex EVAR techniques.
Key findings
- Indirect methods yielded a pooled mean PSD of 3,115 mGy, significantly higher than the 558 mGy from direct methods (P < 0.001).
- Reported PSD values ranged from 63 mGy to 6,600 mGy across studies.
- No significant difference in PSD was found between standard (1,326 mGy) and complex EVAR (2,719 mGy; P = 0.33).
- Direct measurement methods accounted for approximately 57.9% of reported PSD values.
Why it matters
Understanding the discrepancies in PSD measurement methods is crucial for assessing radiation risk during EVAR procedures. Accurate PSD determination can help inform safety protocols and improve patient outcomes in vascular surgery.
