The clinical value of the special functions of DSA in interventional embolization for uterine fibroids

Objective: To evaluate the special functions of DSA in interventional embolization therapy for uterine fibroids. Methods: The special functions of DSA, including 3D-DSA, the optimal working position and road-mapping technique, were utilized in performing interventional embolization therapy for uterine fibroids in twenty-six cases (experimental group). Routine DSA angiography was employed in twenty cases(control group). The volume of contrast media used, the time of completing the interventional procedure and the total fluoroscopic time in two groups were compared and the results were analyzed. Results: The difference in the volume of contrast agent used and in the total fluoroscopic time between two groups was statistically significant (P < 0.05), although no significant difference in the time of completing interventional procedure existed between two groups (P > 0.05). Conclusion: In treating uterine fibroids with interventional embolization, the use of the special functions of DSA can reduce the manipulation time and lower the operation risk. Moreover, the technique of visible 3D reconstruction image is of great significance in guiding the procedure. (authors)
