To evaluate the safety and effectiveness of core needle biopsy (CNB) under the assistance of hydrodissection (HDS).
Of 2325 patients requiring biopsy of thyroid lesions, 21 high-risk patients with subcapsular nodules smaller than 10 mm were recruited into this study. All patients underwent HDS with 0.9% saline solution followed by ultrasound (US)-guided CNB with an 18-gauge semi-automated biopsy needle. The separation success rate (SSR) of the HDS, technical success rate (TSR) of CNB, histopathologic success rate (HSR), and complications were assessed.
Both the SSR of HDS and TSR of CNB were 100% (21/21). The HSR of the thyroid nodules was 85.7% (18/21). No major complications were recorded.
HDS before CNB can successfully lead to safe biopsy of small subcapsular thyroid nodules.

评估水分离（HDS）辅助下进行核心针穿刺活检（CNB）的安全性和有效性。
在需要甲状腺病变活检的 2325 名患者中，招募了 21 名有高风险的、直径小于 10mm 的甲状腺被膜下结节患者。所有患者均接受 0.9%生理盐水 HDS，随后行超声（US）引导下 18G 半自动化活检针 CNB。评估水分离的分离成功率（SSR）、CNB 的技术成功率（TSR）、组织病理成功率（HSR）和并发症。
HDS 的 SSR 和 CNB 的 TSR 均为 100%（21/21）。甲状腺结节的 HSR 为 85.7%（18/21）。未记录到主要并发症。
CNB 前进行 HDS 可成功安全地对小的甲状腺被膜下结节进行活检。
