Transcatheter Arterial Embolization for Intramammary Hemorrhage Caused by a Seat Belt Injury: Case Series Including Experience with N-butyl-2-cyanoacrylate

Abstract

In this study, we report two cases of transcatheter arterial embolization for intramammary hemorrhage caused by seat belt injuries. All patients were female drivers involved in traffic accidents. In each case, we accessed the hemorrhage through the left brachial artery and embolized the perforating branch of the left internal mammary artery with N-butyl-2-cyanoacrylate, obtaining effective hemostasis. Transcatheter arterial embolization is considered effective for breast hemorrhage because of rare but dangerous seat belt injuries.

A Seat Belt Injury Causing a Large Breast Hematoma: A Case Report

“…We present the cases of breast injury with active bleeding reported during 2000-2022 in Endovascular or surgical hemostasis has been recommended for active bleeding, but recently there have been reports of conservative treatment of active bleeding. We consider that endovascular treatment or surgical hemostasis is highly necessary in the following cases: unstable circulation with multiple or severe trauma, severe pain; respiratory depression caused by local compression; abnormal skin findings due to worsening local circulation caused by breast swelling [14]; or when there are significant coagulation abnormalities. If none of the above conditions apply, we suggest conservative therapy, such as compression hemostasis under monitoring, as the first step for class 4 cases.…”

“…A similar case treated with symptomatic therapy was reported by Teh et al [ 10 ]. We present the cases of breast injury with active bleeding reported during 2000-2022 in Table 1 [ 7 , 10 - 14 ].…”
