Preoperative Uterine Artery Embolization in Women Undergoing Uterus-Preserving Myomectomy for Extensive Fibroid Disease: A Retrospective Analysis.

OBJECTIVES: The aim of this study was to determine if a long versus short interval between preoperative uterine artery embolization (PUAE) and subsequent myomectomy impact perioperative blood loss and the complication rate in cases of enlarged multi-fibroid uterus. DESIGN: In cases of an enlarged multi-fibroid uterus, operative myomectomy can lead to heavy blood loss and consequently increases the risk for transfusion and hysterectomy. PUAE can possibly contribute to a reduction of these risks. Our study was designed to determine if a long versus short interval between PUAE and subsequent surgery impacts perioperative blood loss and complication rate. PARTICIPANTS AND METHODS: PUAE was performed 24 h before the planned myoma enucleation in 21 patients between January 2011 and March 2016 (group 1) or 19 days before the operation in 23 patients from March 2016 to May 2018 (group 2). A comparison was made to a historical sample of 57 patients with large myomas (>10 cm) without PUAE (group 3). Perioperative blood loss, need for postoperative blood transfusion, and postoperative complications were recorded. Subjective improvement of myoma-related symptoms was assessed for each group by a questionnaire. RESULTS: PUAE was carried out successfully without complications in all patients. Conversion to hysterectomy was not needed in any of the PUAE patients but was necessary in one of the control patients. In the three groups' comparison, there was a significant lower risk for high blood loss (≥500 mL) in group 1 and a lower but not significant lower risk in group 2 compared to group 3 without an embolization preoperatively. Also, a significant lower risk for postoperative blood transfusion for group 1 (OR 0.02; 0.001-0.328; p = 0.01) and 2 (OR 0.02; 0.001-0.277; p = 0.01) compared to group 3 was observed. The postoperative complication risk was lower in group 2 (model 1: OR 0.12; 0.016-0.848; p = 0.03; model 2 OR 0.07; 0.009-0.588; p = 0.01) compared to group 3. In the context of the postoperative questionnaire, 10 of 11 patients in group 1, 12 of 12 patients in group 2, and 31 of 36 patients from the control group reported an improvement of their complaints. CONCLUSION: PUAE is beneficial for uterus-preserving removal of myomas from patients with a substantially enlarged uterus. There is a significant reduction of high blood loss (≥500 mL), need for postoperative blood transfusion, and postoperative complications in patients with extensive fibroid disease after PUAE compared to no intervention before myoma enucleation.

Analysis of presurgical uterine artery embolization (PUAE) for very large uterus myomatosus; patient's desire to preserve the uterus; case series and literature review. / Analyse der präoperativen Uterus-Arterien-Embolisation (PUAE) bei großem Uterus myomatosus und Patientenwunsch nach Uteruserhalt ­ Fallserie und Literaturübersicht.

PURPOSE: Purpose of this paper to present results of a group of 21 consecutive patients who underwent uterine artery embolization (UAE) immediately before myomectomy. Surgical myomectomy can lead to a substantial blood loss in case of large or multiple tumors due to the hypervascularization of the tumors. This may lead to multiple blood transfusion or hysterectomy. In cases were the preservation of the uterus is demanded, pre-operative embolization could reduce the risk of substantial bleeding. MATERIALS AND METHODS: Between January 2011 and March 2016, 21 patients underwent UAE 24 hours before myomectomy. All patients were asked by questionnaire about post-surgical follow-up, complications, the length of the scar, satisfaction and improvement of symptoms. Data of the operation and embolization were retrospectively assessed. RESULTS: UAE could be performed in all patients without complications. Mean diameter of the largest myoma was 12.7 ±â€Š3.2 cm, primary preservation of the uterus succeeded in all cases. In none of the cases a perioperative blood transfusion was necessary. One patient underwent hysterectomy in another hospital after primary successful resection, one patient received transfusion of 2 bags of red blood cell concentrate during her stay in hospital.11 of 21 patients responded to the questionnaire. 10 of 11 had subjective symptom improvement. Mean inability to work was 31 days, the mean self-measured length was 12 cm. 9 of 11 patients would recommend the procedure, one patient was in the second trimester of pregnancy. CONCLUSION: Preoperative uterine artery embolization facilitates a safe and uterus-preserving myomectomy in patients with very large or multiple fibroids. KEY POINTS: · Uterus-preserving myomectomy can be used in cases of large uteri or with multiple fibroids with low amount of blood loss.. · The combination of preoperative embolization and subsequent myomectomy may be a therapeutic option in cases of infertility due to a fibroid-induced uterine deformation.. · Good interdisciplinary cooperation is essential for sustainable results in this complex group of patients..
