Analysis of bleeding after ultrasound-guided needle biopsy of benign cervical lymph nodes

AIM: Summarized the incidence of bleeding after ultrasound-guided coarse needle biopsy (US-CNB) of benign cervical lymph nodes. METHODS: We retrospectively examined the clinical and follow-up records of 590 patients with benign cervical lymph node disease who underwent US-CNB at our hospital during February 2015–July 2022 and were confirmed to have the disease by CNB and surgical pathology. The number of cases, types of diseases, and degree of bleeding of all patients with bleeding after US-CNB were statistically analyzed. RESULTS: Of the 590 patients, bleeding was noted in 44 cases(7.46%), and the infectious lymph node bleeding rate was 9.48%. Infectious lymph nodes were more likely to bleed than noninfectious lymph nodes after CNB, ,x(2) = 8.771; P = 0.003, Lymph nodes with pus were more likely to bleed than solid lymph nodes after CNB, x(2) = 4.414; P = 0.036,. CONCLUSION: The bleeding of all patients after CNB was minor bleeding. Infected lymph nodes bleed more frequently than noninfected lymph nodes. Lymph nodes with mobility and a large pus cavity, are more likely to bleed after CNB.
