Abstract
PURPOSE: We aimed to evaluate the safety and effectiveness of ultrasonography (US) guided core needle biopsy (CNB) with hydrodissection to diagnose small lymph node metastases adjacent to cervical large vessels. METHODS: From January 2013 to October 2017, 31 patients with 31 cervical lymph node metastases adjacent to large vessels presented for US-guided CNB. The mean maximal diameter of lymph nodes was 0.93±0.16 cm (range, 0.6-1.2 cm). All patients underwent US-guided CNB with 18-gauge true-cut biopsy needle after hydrodissection with saline. The separation success rate (SSR) of the hydrodissection, technical success rate (TSR) of CNB, histopathologic success rate (HST), and complications were assessed. RESULTS: The SSR of hydrodissection was 100% (31/31). After effective separation between the lymph node metastases and the adjacent large vessels with saline injection, the procedures of CNB were performed with a TSR of 100% (31/31). The HST of the lymph node metastases was 100% (31/31). Two patients complained of mild cervical swelling sensation during saline injection. No major complications such as injury of the large vessels or massive hemorrhage occurred. CONCLUSION: Hydrodissection can facilitate safely and effectively US-guided CNB of subcentimeter cervical lymph nodes adjacent to large vessels, potentially impacting further therapeutic decisions.
