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

Abstract

Breast pseudoaneurysms after a core needle biopsy are a rare complication with a low incidence. However, it is important to be aware of the possibility of complications that require treatment.

Breast pseudoaneurysm: two case reports

“…Its incidence is 0.05%-0.5%. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] PSA is produced by a local trauma generating transmural disruption of the vascular wall and the arterial pressure of the blood cuts up the adjacent tissues, creating a sac that communicates with the lumen of the vessel. This sac is surrounded by 2 layers, the media, and the adventitia.…”

“…PSAs can also be secondary to surgery, penetrating chest trauma, local infection, and burns. [2][3][4][5]7,8,10,12,13,[15][16][17]19,20 PSA is a rare complication of interventional breast procedures (core needle or vacuum-assisted biopsy). Some researchers have been reported PSA in which the superficial thoracic artery and the internal mammary artery were affected due to iatrogenic trauma.…”

“…PSA can measure 1cm to 3cm and connects with the artery that originates it. 3,4,6,9,12,15,16,17,18,20 After 3 weeks, PSA is heterogeneous mass with an anechoic center and hyperechogenic ring. Three months later, PSA appears with echogenic material inside the nodule and with absent of vascularity using color Doppler due to spontaneous thrombosis.…”

Breast pseudoaneurysm after core needle biopsy in a pregnant patient

“…Pseudoaneurysms of the breast are rare complications of percutaneous breast interventions [1] , [2] , [3] , [4] , 8] . Some authors have explored local complications of invasive and percutaneous breast procedures during pregnancy [6] .…”

“…Breast pseudoaneurysms are extremely rare complications of interventional breast procedures [1] , [2] , [3] , [4] . An arterial pseudoaneurysm is caused by damage to the arterial wall.…”
