Iatrogenic Axillary Pseudoaneurysm Caused by Ultrasound-guided, Vacuum-assisted Biopsy of the Axillary Lymph Node: A Case Report

Arterial pseudoaneurysms are contained ruptures of the arterial wall that require prompt intervention. Iatrogenic may result from various diagnostic and therapeutic procedures. axillary quite rare, with few reported cases in literature. We report a case 45-year-old woman who sustained an pseudoaneurysm after ultrasound-guided, vacuum-assisted biopsy lymph node. An arteriovenous fistula developed concomitantly. Despite two image-guided treatments, thrombin injection endovascular coil embolization, had persistent flow was ultimately surgically resected at time when patient underwent mastectomy for breast cancer.
