Clinical Report: Fine Needle-Assisted Puncture in CT-Guided Procedures
Overview
This study demonstrates the feasibility and safety of a fine-needle-assisted, two-step puncture technique in CT-guided percutaneous interventions, showing improved accuracy and reduced procedure times compared to conventional methods. The technique was successful in all cases, with no major complications reported.
Background
CT-guided percutaneous procedures are essential for minimally invasive diagnostics and interventions, yet they carry risks of complications such as pneumothorax and bleeding. Traditional methods often struggle with challenging target locations, necessitating repeated punctures and operator skill. The introduction of a fine-needle-assisted technique aims to enhance precision and reduce complications in these complex cases.

Key Findings
The fine-needle-assisted technique achieved a 100% success rate in initial needle placement.
Fewer repositioning attempts were required in the fine-needle-assisted group compared to the conventional group (0.9 vs. 2.2).
Puncture times were significantly shorter in the fine-needle-assisted group (12.05 min vs. 14.95 min).
No major complications occurred in either group during the procedures.
The technique is particularly beneficial for challenging target locations, such as small nodules near critical structures.
Clinical Implications
The fine-needle-assisted puncture technique can enhance the safety and efficiency of CT-guided procedures, particularly in challenging anatomical locations. Clinicians may consider adopting this method to improve patient outcomes and reduce procedure-related complications.
Conclusion
The fine-needle-assisted puncture technique is a promising advancement in CT-guided interventions, offering improved accuracy and safety over conventional methods. Further studies may help to validate its broader application in clinical practice.
