II. Uterine fibroid embolization: technical aspects

Abstract

Successful superselective catheterization of the uterine artery requires familiarity with female pelvic arterial anatomy, knowledge of effective catheter and guidewire combinations, and a few tricks. A learning curve can be expected for each of these elements, although it is assumed that the operator will already have experience in basic catheter techniques. Safe transcatheter delivery, understanding of embolization end points, and avoidance of nontarget embolization are essential. Equally important are knowledge of the properties of the embolic agents currently available and their indications for use. Uterine fibroid embolization unavoidably results in radiation exposure to the uterus and ovaries, and adherence to meticulous fluoroscopic technique is crucial to keep the absorbed dose as low as possible.
