Diagnosis value of ultrasound guiding core needle biopsy in diagnosing lymph node metastases adjacent to cervical large vessels under hydrodissection assistance

目的评价超声引导液体隔离法辅助粗针穿刺活检对诊断颈部大血管旁淋巴结转移癌的临床应用价值。方法回顾性分析2013年1月~2016年11月解放军总医院介入超声科24例恶性肿瘤患者的临床资料,共24枚颈部淋巴结转移癌,病灶平均最大径为(0.93±0.16)cm,均位于颈部Ⅳ区大血管旁,在超声引导下通过局部注射生理盐水行液体隔离法,辅助完成18G粗针穿刺活检,标本送组织病理学检查。结果 100%(24/24)的患者局部注射生理盐水后实现了病灶与相邻大血管的有效分离,并完成了粗针穿刺活检操作。术后无损伤血管及大出血等并发症出现。结论超声引导液体隔离法辅助粗针穿刺活检是诊断颈部大血管旁淋巴结转移癌的一种安全有效方法。

Objective To evaluate the clinical value of core needle biopsy （CNB） under hydrodissectionassistanceto diagnose lymph node metastases close to cervicallarge vessels guided by ultrasound （US）. Methods From January 2013 to November 2016,in the Department of Interventional Ultrasound, Chinese PLA General Hospital, the clinical data of 24 patients with 24 lymph node metastases adjacent to large vessels at the fourth region of the neck were retrospectively analyzed. All the lymph node metastases were performed the procedure of US-guided CNB using 18G true-cut biopsy needle under assistance of local saline injection,the samples were givenhistopathological examination. The mean maximal diameter of the nodules was （0.93±0.16） cm. Results Following the effective separation between the lymphnode metastases and the adjacent vessels with hydrodissection of saline injection, the procedures of CNB were completely performed in 100% （24/24） patients and the diagnoses of the lymph node metastases in all cases were verified histopathologieally. No major complications including large vessels injury and massive haemorrhage occurred. Conclusion US-guided CNB under assistance of hydrodissection is an effective and safe methodto diagnose cervical lymph node metastases adjacent to large vessels.
