Abstract
SUMMARY: Iatrogenic pseudoaneurysm is a rare but potentially fatal complication of a thyroid biopsy. However, a standard management strategy has not yet been established. We aimed to evaluate the efficacy and safety of ultrasound (US)-guided thrombin injection (TI) for thyroid pseudoaneurysms. This retrospective study included 7256 patients who underwent thyroid biopsy and TI from January 2020 to January 2024. The technical success, clinical efficacy, and complication rates were evaluated. A total of 0.1% (7/7256) of pseudoaneurysms developed after thyroid biopsy. Except for 1 case that showed obliteration with manual compression, the remaining 6 refractory aneurysms (0.08%) were managed with US-guided TI. All cases (100%) were successfully occluded with US-guided TI. No major complications were observed. One patient (16.7%) developed transient loss of consciousness, which spontaneously resolved within a few seconds. US-guided TI is an effective, relatively safe, and minimally invasive method for managing pseudoaneurysms after thyroid biopsy.
