Risk-adapted trajectory selection for ultrasound-guided thyroid fine-needle aspiration biopsy: a multicenter study of in-plane and out-of-plane approaches
Clinical Report: Evaluation of Needle Approach Strategies in Ultrasound-Guided Thyroid FNAB
Overview
This multicenter study evaluated the diagnostic adequacy of in-plane versus out-of-plane needle approaches in ultrasound-guided fine-needle aspiration biopsy (FNAB) of thyroid nodules.
Background
Ultrasound-guided FNAB is a critical procedure for assessing thyroid nodules, with diagnostic adequacy being essential for effective patient management. Nondiagnostic cytology can lead to repeat procedures and delays in treatment, making the choice of needle approach significant. Understanding the impact of different needle techniques on diagnostic outcomes can enhance clinical decision-making.

In-Plane
98.3%
< 0.001
Out-of-Plane
85.7%
Key Findings
The in-plane approach had a diagnostic adequacy of 98.3%, compared to 85.7% for the out-of-plane approach (P < 0.001).
Adjusted odds ratios indicated a significant association of the in-plane approach with diagnostic adequacy in both primary and validation cohorts.
Satisfactory needle-tip visualization was more frequent with the in-plane approach (97.2% vs. 63.6%; P < 0.001).
Immediate hematoma rates were similar between the two approaches (6.2% vs. 9.2%; P = 0.234).
The study included 506 thyroid nodules across three tertiary hospitals.
Clinical Implications
The findings indicate differences in diagnostic adequacy between needle approaches in ultrasound-guided FNAB of thyroid nodules.
Conclusion
The in-plane approach is associated with higher diagnostic adequacy without a significant increase in immediate hematoma.
