ABSTRACT
OBJECTIVE:
To assess success and safety of CT-guided procedures with narrow window access for biopsy.METHODS:
Three hundred ninety-six consecutive patients undergoing abdominal or pelvic CT-guided biopsy or fiducial placement between 01/2015 and 12/2018 were included (183 women, mean age 63⯱â¯14 years). Procedures were classified into "wide window" (width of the needle path between structures >â¯15 mm) and "narrow window" (≤â¯15 mm) based on intraprocedural images. Clinical information, complications, technical and clinical success, and outcomes were collected. The blunt needle approach is preferred by our interventional radiology team for narrow window access.RESULTS:
There were 323 (81.5%) wide window procedures and 73 (18.5%) narrow window procedures with blunt needle approach. The median depth for the narrow window group was greater (97 mm, interquartile range (IQR) 82-113 mm) compared to the wide window group (84 mm, IQR 60-106 mm); pâ¯=â¯0.0017. Technical success was reached in 100% (73/73) of the narrow window and 99.7% (322/323) of the wide window procedures. There was no difference in clinical success rate between the two groups (narrow 86.4%, 57/66; wide 89.5%, 265/296; pâ¯=â¯0.46). There was no difference in immediate complication rate (narrow 1.3%, 1/73; wide 1.2%, 4/323; pâ¯=â¯0.73) or delayed complication rate (narrow 1.3%, 1/73; wide 0.6%, 1/323; pâ¯=â¯0.50).CONCLUSION:
Narrow window (<â¯15 mm) access biopsy and fiducial placement with blunt needle approach under CT guidance is safe and successful. CLINICAL RELEVANCE STATEMENT CT-guided biopsy and fiducial placement can be performed through narrow window access of less than 15 mm utilizing the blunt-tip technique. KEY POINTS ⢠A narrow window for CT-guided abdominal and pelvic biopsies and fiducial placements was considered when width of the needle path between vital structures was ≤â¯15 mm. ⢠Seventy-three biopsies and fiducial placements performed through a narrow window with blunt needle approach had a similar rate of technical and clinical success and complications compared to 323 procedures performed through a wide window approach, with traditional approach (>â¯15 mm). ⢠This study confirmed the safety of the CT-guided percutaneous procedures through <â¯15 mm window with blunt-tip technique.Palabras clave
