OVERVIEW

  • + Retrospective data from 129 procedures using SPiN Perc™ in 10 centers
  • + Data analyzed for lesion characteristics, diagnostic yield, and adverse events
  • + Mean nodule size: 27.31 mm
  • + Mean nodule distance from pleura: 23.2 mm
  • + On average, physicians made 1 initial pass with the introducer needle into the lesion and took 2 FNA samples and 5 core biopsies

KEY TAKEAWAYS

  • + Diagnostic yield: 73.7% SPiN Perc™ samples only, 81.1% combined with navigated bronchoscopy
  • + Complication rate: 22.5% adverse events – of these, 17.8% were pneumothoraces
  • + Results demonstrated electromagnetic guided percutaneous lung biopsy approach using SPiN Perc™ yields a high diagnostic rate with minimal safety concerns
  • + A main added benefit of SPiN Perc™ is the ability to stage a nodule using a combined bronchoscopic and percutaneous approach in the same procedural setting

AUTHORS’ CONCLUSION
“In this study, we show that an EM-guided percutaneous lung biopsy approach yields a high diagnostic rate with minimal safety concerns and the added benefit of using a combined bronchoscopic and percutaneous staged approach to pulmonary nodule diagnostics in a single procedural setting.”
