Pseudoaneurysm after Ultrasound-Guided Vacuum-Assisted Core Breast Biopsy

A case report of pseudoaneurysm after a core needle biopsy of breast cancer

“…Damage to the three layers of the arterial wall occurs, with the leakage and accumulation of blood outside the vessel and the formation of a hematoma contained by the surrounding tissues, which may develop its own fibrous encapsulation . It is most common in older patients, patients with atherosclerotic disease, and those on anticoagulant therapy …”

“…Fourteen cases of breast pseudoaneurysms have been reported in the literature: eleven after central breast biopsy, one case by puncture and fine‐needle aspiration cytology (FNAC), and one case after surgical biopsy. Of the cases after central mammary biopsy, ten were performed with a 14 G needle and the remaining with a 18G needle …”

“…The most common complication is the hematoma . Although there are some breast pseudoaneurysms cases reported in the literature after a CNB, their incidence is low . We present a breast pseudoaneurysm case report after a CNB of a palpable ultrasound‐guided breast nodule.…”

A Novel Treatment of Very Rare Anomaly; Breast Pseudoaneurysm Developed During Pregnancy

“…Breast pseudoaneurysms are fairly rare, the available reported aneurysms are iatrogenic pseudoaneurysms which are usually seen after breast biopsies and vacuum assisted removal procedures . Significant hemorrhage during the procedure has been reported in patients who developed breast pseudoaneurysms after the procedure.…”

“…P seudoaneurysms that develop from an arterial supply of breast are quite rare, and the cases reported in literature are mostly secondary to ultrasound guided or stereotactic core biopsies (1)(2)(3)(4)(5)(6)(7)(8)(9). Two cases of breast pseudoaneurysm due to a blunt trauma are reported in literature (10,11).…”
