Assessment of extravasation on ruptured uterine artery pseudoaneurysm using contrast-enhanced ultrasonography during uterine balloon tamponade.

ABSTRACT:

Objective

Contrast-enhanced ultrasonography (CEU) has been used in critical trauma situations to visualize extravasation; however, its use is limited in the field of obstetrics. Cases of ruptured uterine artery pseudoaneurysm (UAP) were analyzed to clarify the efficacy to CEU during uterine balloon tamponade.

Methods

Cases of ruptured UAP diagnosed at a teaching university hospital from January 2015 to December 2017 were retrospectively analyzed. UAP was diagnosed using color Doppler ultrasonography. Extravasation was identified using computed tomography and double checked using CEU with an intravenously administered contrast agent (Sonazoid; Daiichi Sankyo Company, Ltd., Tokyo, Japan) and an ultrasound instrument (HI VISION Preirus; Hitachi Aloka Medical, Ltd., Tokyo, Japan
