“…In the present study, one patient with chronic renal failure developed hemorrhagic complications. If the patient is taking an anticoagulant or antithrombotic, stopping the medication for 3 -10 days is recommended before and after US-FNA (4,5,9,11,17,18). However, performing US-FNA in patients taking anticoagulant or antithrombotic remains controversial and lacking in evidence, such as randomized controlled study (2,4,7,9,16,33).…”

Background: Thyroid nodules are a common clinical problem and ultrasound-guided fine needle aspiration (US-FNA) biopsy is widely used for evaluation of thyroid nodules. However, few studies have addressed the contributing factors to hemorrhage after US-FNA of thyroid nodules. Objectives: To assess the contributory factors related to patient characteristics, ultrasound (US) features of the thyroid nodules, and the US-FNA procedures to affect hemorrhage complications after US-FNA of thyroid nodules. Methods: Between March 2014 and April 2015, 366 consecutive patients who underwent US-FNA of thyroid nodules were enrolled in this retrospective study. The characteristics of hematomas, including the location, maximum size, and clinical course, were assessed. The relationships between hematomas and factors related to the medical characteristics of patients, US characteristics of the nodules, and FNA procedural factors were analyzed. Results: Data on 365 nodules in 321 patients who underwent US-FNA of thyroid nodules were analyzed. Minor hemorrhagic complications developed in 14 (3.8%) of the 365 nodules. There were no statistically significant differences between patients taking or not taking an anticoagulant or antithrombotic (P = 0.270). Factors related to increased risk of hematoma were male sex (P = 0.031), larger maximum size (P = 0.002), a cystic or predominantly cystic nodule (P < 0.0001), a probable benign nodule (P < 0.0001), thicker needle size (P < 0.0001), and a greater number of the needle passes (P = 0.005). Conclusions: US-FNA can be performed safely even in patients taking anticoagulant or antithrombotic agents. Factors related to hemorrhagic complications are male sex, larger nodules, cystic or predominantly cystic nodules, probably benign nodules, thicker needles and a greater number of needle passes.

The incidence of PTMC has been increasing in the recent years. This study aimed to investigate the diagnostic value of US‐FNA in thyroid nodules ≤1 cm and whether the presence of Hashimoto's thyroiditis (HT) in thyroid could influence the accuracy. The patients who accepted US‐FNA at FUSCC from December 2012 to November 2015 and followed our criteria were enrolled in this study. We extracted the cytological, pathological, and follow‐up US/US‐FNA data of patients with subcentimeter nodules. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), false‐negative rate (FNR), false‐positive rate (FPR), and AUC were calculated to define FNA diagnostic performance in patients. The association of HT with cytological results was analyzed in univariate and multivariate logistic regression analysis. In total, 754 patients with 817 subcentimeter nodules were collected to comprise the FUSCC cohort. Of the 817 nodules, the cytological results were ND/UNS in 80 nodules (9.8%), benign in 74 (9.1%), AUS/FLUS in 80 (9.8%), FN/SFN in 6 (0.7%), suspicious for malignancy (SM) in 222 (27.2%), and malignant in 355 (43.5%). The sensitivity, specificity, PPV, NPV, and AUC of US‐FNA for the subcentimeter nodules were 98.8%, 90.5%, 98.8%, 90.5%, and 94.7%, respectively. In comparison with HT‐positive subcentimeter nodules, the diagnostic value of US‐FNA for HT‐negative nodules was significantly higher (HT‐positive: AUC = 91.6%, HT‐negative: AUC = 95.9%, P = 0.028). The coexistent HT was found to increase the risk of the FNR and indeterminate cytological results. US‐FNA demonstrated an effective method for diagnosis of subcentimeter thyroid nodules with a low nondiagnostic rate in our study. The presence of HT in thyroid could be a risk factor for the increased FNR and indeterminate cytological results during US‐FNA.
