Uterine artery embolization for fibroids does not have adverse effects on ovarian reserve in regularly cycling women younger than 40 years

Clinical Outcomes of Conservative Surgery for Diffuse Uterine Leiomyomatosis: Preliminary Experience of 17 Cases in a Single Center

This study aimed to introduce the clinical outcomes of conservative surgery for diffuse uterine leiomyomatosis, which also included the specialized surgical technique. All patients with diffuse uterine leiomyomatosis underwent conservative surgery such as transient occlusion of the uterine arteries (TOUA) adenomyomectomy. All 17 surgeries were performed by a single surgeon between 2018 and 2021. The mean age of the 17 patients was 36.12 years old (range 29-48, SD = 5.4). Fourteen of the 17 patients received a previous myomectomy via a laparotomic (6, 35.3%), laparoscopic (6, 35.3%), or hysteroscopic (2, 11.8%) approach. The major symptom was menorrhagia (94.1%); the mean operation time was 97.06 min (70-160, SD = 22.71), and the mean estimated blood loss was 283.53 mL (20-1000, SD = 273.72). The mean hemoglobin level one day after the operation was 9.64 g/dL (7.2-13.1, SD = 1.85). The mean hospital stay was 6.47 days (6-8, SD = 0.62). The mean follow-up duration was 116.41 weeks (32-216, SD = 50.88). The recurrence rate was 5/17 (29.4%), and the recurrence-free interval was 50.6 weeks (27-87, SD = 23.71). In patients with diffuse uterine leiomyomatosis, who want fertility preservation and relief of disease-related symptoms, conservative surgery such as TOUA adenomyomectomy could be a good option to preserve the uterus. However, further studies are required to assess fertility outcomes with a long-term follow-up.

Evaluation of the relationship between ovarian reserve with congenital anomalies and intramural uterine leiomyoma among infertile women: a cross-sectional study

BACKGROUND

Ovarian reserve is a crucial indicator of a woman's fertility potential, which is determined by the quality and quantity of antral follicles and oocytes. However, certain factors such as endometriosis, pelvic inflammatory disease, myoma, and the natural process of aging can lead to a poor ovarian response to stimulation, reducing a woman's chances of conceiving.

OBJECTIVE

To evaluate the effect of uterus congenital anomalies and uterine leiomyoma are associated on ovarian reserve.

METHODS

The present cross-sectional study was performed on 321 infertile women in three groups consisted of 97 infertile women with intramural uterine leiomyoma and 81 infertile women with uterine anomalies and 143 infertile women without uterine anomalies and uterine leiomyoma during 2017-2019 in Royan Center. Sampling method was continuous and available. Data collection tool in this study was a questionnaire which was in two parts of individual variables and the second part was related to ultrasound results (number of antral follicles and ovarian volume) and laboratory tests (Anti-Mullerian Hormone (AMH) and Follicle-stimulating Hormone (FSH)). Ovarian reserve parameters were measured in three groups on the third day of the cycle in both groups. Data analysis was performed using SPSS software version 21. Quantitative variables were analyzed using t-test, qualitative variables were analyzed using chi-square test.

RESULTS

The results of in laboratory parameters showed that there was no statistically significant difference between the three groups in FSH (2.35 ± 1.55, 2.07 ± 1.81, 2.31 ± 1.93) and AMH (6.84 ± 2.75,7.52 ± 3.14,6.93 ± 3.04), respectively (P > 0.05). The results of sonographic variables also showed that the variables include number of antral follicles in right ovarian, number of antral follicles in left ovarian have statistically significant between the three groups (5.73 ± 2.69,4.84 ± 3.14,6.66 ± 3.13), respectively (P < 0.05).

CONCLUSION

The results of the present study showed that uterine abnormalities and uterine leiomyoma with different mechanisms such as reduce of antral follicle numbers and the effect on uterine and ovarian blood flow lead to a decrease in ovarian reserve and infertility. Therefore, treatment and surgery can reduce these effects and improve the fertility of the affected women.

Pregnancy and its Outcomes in Patients After Uterine Fibroid Embolization: A Systematic Review and Meta-Analysis

Uterine artery embolization (UAE) has been introduced for uterine fibroid treatment for two decades. Most of the patients are in reproductive age and many want future pregnancy. In this study, we will assess fertility, pregnancy and its outcomes in patients who have undergone UAE. In this systematic review, a systematic search was performed on important databases including PubMed and Medline, Web of Knowledge, Google Scholar, EMBASE and Scopus. Studies reported enough data about pregnancy after UAE were considered to be enrolled in the review. We assessed obstetric indices (pregnancy and delivery rates, pregnancy losses, complications and fetal outcomes). Study evaluation was done based on STROBE checklist by two reviewers. Totally, 24 original papers were included. Data were analyzed by Stata and MedCalc softwares. Among women wishing fertility, totally 40.5% experienced at least one pregnancy after UAE (95% confidence interval [CI]: 33.3%-48.2%). Pooled estimate of pregnancy loss rate was 33.5% (95% CI: 26.3-41%). Most pregnancy losses were due to spontaneous abortion (81.3% of all losses (95% CI = 76%-86.1%)). Rate of obstetrical complications was 25.4% (95% CI = 13-40.2%) among all finished pregnancies. Pooled estimate of preterm labor was 12.8% (95% CI = 8.7%-17.5%), and pooled estimate of low birth weight (LBW) was 10% (95% CI = 6.2-14.6%). Considering the findings of the study, a safe pregnancy after UAE is obviously possible resulting to a healthy and normal baby delivery. In addition, pooled obstetrical complication rates, pregnancy losses, preterm labor and LBW seem to be mostly similar to the general population. Registration: The study was registered in International Prospective Register of Systematic Reviews (PROSPERO) on Nov 3, 2017, and was confirmed with a registration code of CRD42017076074.

Efficacy comparison of transcatheter arterial embolization with gelatin sponge and polyvinyl alcohol particles for the management of cesarean scar pregnancy and follow-up study

AIM

The aim of this study was to compare the therapeutic efficacy of transcatheter arterial embolization (TAE) with gelatin sponge (GS) and polyvinyl alcohol (PVA) particles for cesarean scar pregnancy (CSP).

METHODS

A total of 35 patients with CSP, who were classified into either the GS group (n = 22) or the PVA group (n = 13), underwent TAE and postoperative ultrasound-guided curettage. Their hospital stay, first-scheme success rate, intra-curettage blood loss, serum β-human chorionic gonadotropin (hCG) level, and other indicators were simultaneously recorded. During the follow-up period, time for the serum β-hCG level to return to normal, time for the return of menstrual cycle, and menstrual blood volume were recorded.

RESULTS

Compared with the GS group, patients in the PVA group: (i) were older; (ii) had greater number of abortions or curettages, and had longer times since last cesarean (P < 0.05); (iii) had similar hospital stay and first-scheme success rate (P > 0.05); (iv) had lower, but not significantly different, hemorrhage rate (7.7% vs 36.4%, P = 0.066); (v) had a significantly higher serum β-hCG level at discharge and a smaller drop in serum β-hCG level from admission to discharge (P < 0.05); (vi) had a similar time for the serum β-hCG level to return to normal (P > 0.05); (vii) had a shorter time for the return of menstrual cycle (P = 0.012); and (viii) had a significantly higher incidence of abnormal menstrual blood volume reduction (50.0% vs 8.3%, P = 0.034).

CONCLUSION

TAE with either GS or PVA particles for CSP treatment had relatively good efficacy. During the selection of the ideal embolic agent, the patient's age, hemorrhage risk, and requirement for protecting ovarian function and reserving fertility should be comprehensively considered.

The effects of uterine artery embolization on ovarian reserve

OBJECTIVE

To evaluate the effects of UAE for symptomatic uterine fibroids on ovarian reserve based on AMH.

STUDY DESIGN

This was a retrospective study conducted between March 2011 and October 2014. All women underwent UAE. At baseline and at the 3-month and 12-month follow-up visits, serum anti-Müllerian hormone (AMH), follicle stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels were assessed, and ovarian volume and antral follicle count (AFC) were evaluated in each patient.

RESULTS

There were no statistically significant differences in serum E2, LH, or FSH levels or in ovarian volume 3 or 12 months after UAE (P=0.8194, P=0.3976, P=0.4766, and P=0.6822, respectively). However, AMH and AFC were significantly different 3 and 12 months after the procedure (P=0.00, P=0.029 and P=0.00, P=0.00, respectively). AMH levels remained low after 12 months of follow-up compared to the expected AMH levels. A statistically significant recovery of serum AMH at 12 months compared to at 3 months in those <40 years of age (P=0.00), but not in those ≥40 years (P=0.837).

CONCLUSIONS

Ovarian reserve appears to be affected by UAE in premenopausal women. However, younger ovaries (according to biological ovarian age) exhibit a greater capacity for recovery after ovarian damage. Therefore, larger studies are needed for more conclusive results.

Effects of embolic agents with different particle sizes on interventional treatment of uterine fibroids

Objective:

To compare the effects of embolic agents with different particle sizes on interventional treatment of uterine fibroids (UFs).

Methods:

One-hundred and thirty patients with UFs were divided into a treatment group and a control group (n=65) by random draw. All patients were treated by uterine artery embolization, with the treatment group using 200 μm polyvinyl alcohol (PVA) particles and the control group using 500 μm PVA particles.

Results:

The success rate of embolization was 100%. After intervention, the treatment group was significantly less prone to complications such as lower abdominal pain, fever, nausea, vomiting and bleeding than the control group (P<0.05). The follicle-stimulating hormone levels of both groups were similar before and after intervention, and there were also no significant inter-group differences. The uterine and UF volumes of both groups significantly decreased six months after intervention (P<0.05), and those of the treatment group were significantly lower (P<0.05). The two groups had similar physical function, role-physical, bodily pain and general health scores before intervention, but the treatment group scored significantly higher than the control group did six months after intervention (P<0.05).

Conclusion:

Interventional embolization can well treat UFs, without apparently affecting ovarian functions. Small-sized PVA particles can improve the quality of life by shrinking the uterus and UFs as well as by reducing the risks of complications.

Anti Müllerian hormone levels before and after uterine artery embolization: A preliminary report

OBJECTIVE

To determine the effects of uterine artery embolization on Anti-Müllerian hormone levels for women under 40 years of age.

MATERIAL AND METHODS

Non-randomized, observational study of women under 40 years of age and who received UAE. Twenty-seven women under the age of 40 who underwent UAE were included in the study. Hormone levels were measured prior to UAE, and at least six months post UAE.

RESULTS

Statistical analysis from a paired t-test showed that the AMH levels pre- and post-embolization of these women fell within the normal range. The average AMH level prior to embolization was 2.54 ± 3.99 ng/mL. The mean AMH concentration after embolization was 2.33 ± 2.70 ng/mL. The average change in AMH levels between pre-and post-embolization was -0.21 ± 1.08 ng/mL. There is no statistically significant difference between the pre- and post- UAE AMH levels (95% CI -0.64 to 0.22, p=0.32).

CONCLUSION

UAE does not affect ovarian reserve in women under 40 as evidenced by no significant change in AMH levels before and after embolization. Women who are of reproductive age and have fibroids can consider UAE without concern for adverse effects on their fertility.

Incidence and predictive factors for complications after uterine leiomyoma embolization

STUDY QUESTION

What is the risk of complications after uterine leiomyoma embolization and what are the factors associated with complications?

SUMMARY ANSWER

The cumulative risk of complications after embolization is relatively low even in the long term, but submucosal leiomyoma location may increase the risk.

WHAT IS KNOWN ALREADY

A broad spectrum of complications after leiomyoma embolization have been described with widely varying rates. There is uncertainty over the actual risk of complications and the factors associated with this risk.

STUDY DESIGN, SIZE, DURATION

This was a prospective cohort study of 288 consecutive women undergoing leiomyoma embolization in the general gynaecology clinic of a university teaching hospital between January 2001 and December 2010.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Complications occurring after embolization were categorized as major or minor according to the severity of their impact on health, the level of care required and the outcome. Cumulative complication rates were estimated by survival analysis and log-rank tests according to baseline variables. Multivariable Cox proportional hazards analysis was performed to adjust for confounders.

MAIN RESULTS AND THE ROLE OF CHANCE

There were 48 patients who experienced a complication at a median of 5 months (95% confidence interval, 4.1-11.4) after embolization. Complications were minor in 38 patients and major in 10 patients. The cumulative overall complication rate was 13% (95% CI, 9.0-17.0) at 6 months, 16% (95% CI, 11.0-20.0) at 1 year, 17% (95% CI, 12.0-22.0) at 3 years and 18% (95% CI, 12.9-22.8) at 5 years. The most frequent complication (19/48, 39.6%) was leiomyoma expulsion, which occurred spontaneously in 13 (68.4%) of these cases and required assistance in 6 (31.6%) cases. Eight (2.8%) patients underwent re-intervention, including six hysteroscopic myomectomies, one laparoscopic myomectomy and one hysteroscopic adhesiolysis, as a result of a complication. Submucosal leiomyoma location was the only baseline variable associated with an increased risk for complications [Hazard ratio (HR), 2.28, 95% CI, 1.24-4.18, P = 0.008].

LIMITATIONS, REASONS FOR CAUTION

Our population did not include women of African descent, who have been reported to be at higher risk of post-procedural complications compared with Causcasian women. If such women were involved in the study, higher morbidity rates might have been observed.

WIDER IMPLICATIONS OF THE FINDINGS

Women with submucosal leiomyomas at the time of embolization are more likely to have post-procedural complications. This is important new information for counselling patients contemplating this therapeutic approach.

STUDY FUNDING/COMPETING INTERESTS

The authors have no competing interests to declare. The study was not supported by any external grant.

Incidence and risk factors for clinical failure of uterine leiomyoma embolization

OBJECTIVE

To estimate the incidence of clinical failure after uterine leiomyoma embolization and identify possible risk factors.

METHODS

One hundred seventy-six consecutive women undergoing uterine leiomyoma embolization were followed prospectively for a median of 48 months (range 12-84 months) to estimate the occurrence of clinical failure, defined as persistence or recurrence of leiomyoma symptoms, and any subsequent invasive treatment. Cumulative failure and reintervention rates were estimated by survival analysis and log-rank tests according to baseline patient characteristics. Multivariable Cox proportional hazards analysis was performed to adjust for confounders.

RESULTS

Overall, there were 18 failures at a median of 36 months (range 3-84 months). The cumulative failure rate increased steadily over time, 3% at 1 year, 7% at 3 years, 14% at 5 years, and 18% at 7 years. Of the 18 failures, 11 had reintervention, including six hysterectomies, four myomectomies, and one repeat uterine leiomyoma embolization, at a median of 56 months (range 15-84 months). The cumulative reintervention rate was 0 at 1 year, 3% at 3 years, 7% at 5 years, and 15% at 7 years. Women aged 40 years or younger had a higher failure risk (hazard ratio [HR] 5.89, 95% confidence interval [CI] 2.50-20.02, P=.023) compared with older women. A history of previous myomectomy was also associated with an increased failure risk (HR 3.79, 95% CI 2.07-13.23, P=.037).

CONCLUSION

The 7-year cumulative rates of clinical failure and reintervention after uterine leiomyoma embolization were 18% (95% CI 8.2-27.8) and 15% (95% CI 5.2-24.8), respectively. The failure risk was higher for younger patients and for those with a prior myomectomy.

Embolization of uterine fibroids from the point of view of the gynecologist: pros and cons

Uterine artery embolization (UAE) is a minimally invasive procedure with large symptomatic potential in treatment of women with uterine leiomyomas. Due to specificities of this method and possible complications the appropriate indication is crucial. Patient’ symptoms, age, plans for pregnancy, and surgical and reproductive history play a major role in decision-making regarding appropriate subjects for UAE. Close cooperation between the gynecologist and the interventional radiologist is necessary. UAE is usually offered as an alternative to surgical treatment. In patients with no fertility plans, it is a less invasive option than abdominal hysterectomy, with a comparable effect on fibroid-related symptoms and quality of life. The need for reintervention is markedly greater in patients after UAE (up to 35% within 5 years) than after hysterectomy. Women with large symptomatic fibroids wishing to retain the uterus and ineligible for minimally invasive (laparoscopic or vaginal) hysterectomy are good candidates for UAE. However, studies comparing UAE with minimally invasive hysterectomy are lacking. Use of UAE in younger women desiring pregnancy is more controversial, mainly because of the significant risk of miscarriage (as high as 64% in some studies) as well as the increased risk of other complications of pregnancy, such as preterm delivery, abnormal placentation, and post-partum hemorrhage. The risk of infertility or subfertility following UAE is unknown. Even poor candidates for myomectomy should be carefully selected for UAE after counseling about all possible adverse effects on fertility. Good prospective studies focused on fertility comparing UAE with no treatment or with myomectomy are needed but would be ethically questionable. This review summarizes the current knowledge regarding the benefits and potential risks of UAE from the point of view of the gynecologist, who should be responsible for proper indication of this treatment.

Usefulness of pelvic artery embolization in cesarean section compared with vaginal delivery in 176 patients

PURPOSE

To evaluate the efficacy and safety of transcatheter arterial embolization of the pelvic arteries for the treatment of postpartum hemorrhage (PPH) associated with cesarean section compared with vaginal delivery.

MATERIALS AND METHODS

A retrospective analysis of 176 patients undergoing transcatheter arterial embolization of the pelvic arteries for PPH from January 2006 through August 2011 was conducted at two institutions. The mean patient age was 33.9 years (range, 24-46 years). Data including delivery details, hematology and coagulation results, embolization details, and clinical outcomes were collected. Technical success was defined as cessation of bleeding on angiography or angiographically successful embolization of the bleeding artery. Clinical success was defined as the obviation of repeated embolization or surgical intervention.

RESULTS

The technical success rate was 98.8% (n = 174), and the clinical success rate was 89.7% (n = 158). Among 176 patients, 71 had cesarean sections, and 105 underwent normal vaginal deliveries. Of the 105 patients who underwent normal vaginal deliveries, 11 (10.5%) required repeat embolization or surgical intervention. Of the 71 patients who had cesarean sections, 7 (9.8%) required repeat embolization or surgical intervention. The clinical success rate and complication rate were not related to the mode of delivery. All women resumed menses after transcatheter arterial embolization, and most (n = 125) described their menses as unchanged. Subsequent spontaneous pregnancies occurred in 13 women.

CONCLUSIONS

The cesarean mode of delivery is not a predictor of poorer outcomes of transcatheter arterial embolization; however, further study is needed to clarify this relationship.

Risks for donors in uterus transplantation

Uterus transplantation (UTx) is an alternative to gestational surrogacy and adoption for patients with absolute uterine infertility. Studies have been conducted in animals, and UTx is now within the reach of clinical application in humans. Procedures in humans have been published, but many medical, ethical, and social problems and risks of UTx require discussion prior to widespread clinical application, from the perspectives of donors, recipients, families, and newborns. In this article, we summarize the burdens and risks of UTx, with a focus on donors who provide the uterus.

Hysteroscopy after uterine fibroid embolization: evaluation of intrauterine findings in 127 patients

AIM

Several atypical hysteroscopy findings have been described in association with uterine artery embolization (UAE). The purpose of this study was to evaluate the types and frequency of these findings in the largest published series of patients.

MATERIAL AND METHODS

Premenopausal patients after bilateral UAE for symptomatic intramural fibroid underwent subsequent hysteroscopic examination 3-9 months following UAE. The uterine cavity was examined with focus on specific post-embolization changes. Biopsy of endometrium was obtained and evaluated together with a biopsy of abnormal foci if present.

RESULTS

UAE was performed in a total of 127 women with an average size of dominant fibroid 63.1 mm in diameter and an average patient age of 35.1 years. Even though the majority of patients were asymptomatic at the time of hysteroscopy (78.0%), the post-embolization hysteroscopic examination was normal in only 51 patients (40.2%). The most frequent abnormalities included tissue necrosis (52 women, 40.9%), intracavitary myoma protrusion (45 women, 35.4%), endometrium 'spots' (22.1%), intrauterine synechiae (10.2%) and 'fistula' between the uterine cavity and intramural fibroid (6.3%). Histopathological examination showed normal, secretory or proliferative endometrium in 83.5% patients. Necrosis and/or hyalinization prevailed in the results of biopsy of abnormal loci (45 cases, 35.4%).

CONCLUSION

Frequency of abnormal hysteroscopic findings several months after UAE for primary intramural myomas is high. Alarmingly high is the percentage of patients with a histopathologically verified necrosis. Performing hysteroscopy in selected patients after UAE is necessary before eventual surgical re-intervention, especially in women with reproductive plans.

Transcatheter arterial embolotherapy: a therapeutic alternative in obstetrics and gynecologic emergencies

Transcatheter arterial embolization has become a major treatment modality in a variety of clinical applications, including management of bleeding related to a broad spectrum of obstetric and gynecologic disorders. Embolotherapy has a well-documented role in the management of pelvic and genital tract hemorrhage in the postpartum and postoperative/postcesarean setting. It is also an integral part in the treatment armamentarium of abdominal and cervical ectopic pregnancy, arteriovenous malformation, and gynecologic neoplasms, including more recently, uterine leiomyomata. Based on experiences accumulated over the past decades, embolotherapy has been proven to be highly effective with success rate in the 90 to 100% range in the appropriate clinical settings. It provides visualization of the bleeding site and enables targeted, minimally invasive therapy to achieve hemostasis, which allows preservation of the uterus and hence fertility. In hospitals where experienced personnel and technology is available, transcatheter arterial embolization should be considered in the emergent management of obstetric and gynecologic hemorrhage, particularly when local and conservative measures fail to attain hemostasis.

An efficient conservative treatment modality for cervical pregnancy: angiographic uterine artery embolization followed by immediate curettage

OBJECTIVE

We sought to evaluate a conservative treatment modality, angiographic uterine artery embolization (UAE) followed by immediate curettage, in the treatment of cervical pregnancy.

STUDY DESIGN

Sixteen patients with cervical pregnancy were first treated by UAE to control or prevent vaginal bleeding. Curettage of cervical canal was performed immediately after UAE to remove gestational tissue from the cervix. Clinical outcome assessments include vaginal bleeding, serum β-human chorionic gonadotropin level, cervical mass, menstruation, fertility, and hospitalization time.

RESULTS

Fifteen patients were successfully treated by UAE followed by immediate curettage. One patient at very early gestational age underwent UAE only. Quick regression of serum human chorionic gonadotropin level and cervical mass, fertility preservation, and a short hospital stay were observed.

CONCLUSION

UAE followed by immediate curettage is an efficient conservative treatment for cervical pregnancy. This procedure may become a useful alternative to other conservative approaches.

Long-term effects of uterine fibroid embolization on ovarian reserve: a prospective cohort study

OBJECTIVE

To determine whether uterine fibroid embolization may advance ovarian follicular depletion in reproductive-aged women with apparently normal baseline ovarian function.

DESIGN

Prospective cohort study.

SETTING

University tertiary care center.

PARTICIPANT(S)

Thirty-six patients aged 26 to 39 years with fibroids, regular menstrual cycles, and day 3 serum FSH levels<10 mIU/mL and 36 matched control women.

INTERVENTION(S)

Day 3 serum FSH and E2 levels and ultrasound-based antral follicle count and ovarian volume were determined before (baseline) and at 12, 24, 36, 48, and 60 months after embolization and compared with those of the control group. Menstrual status was determined annually on the basis of prospectively recorded menstrual calendars.

MAIN OUTCOME MEASURE(S)

Longitudinal changes in hormone levels, ultrasound measures, and bleeding patterns.

RESULT(S)

Although the FSH and E2 levels increased significantly and the antral follicle count and ovarian volume values declined significantly over time within the groups, no significant differences were found between the groups. The cycle remained regular in all but two women (one in the embolization group and one in the control group), who started having cycle irregularity after 24 months and 36 months follow-up, respectively.

CONCLUSION(S)

This long-term follow-up study suggests that fibroid embolization does not lead to an accelerated decline in ovarian reserve in younger patients.

Impact of pelvic arterial embolization for intractable postpartum hemorrhage on fertility

OBJECTIVE

This study was to determine the long-term outcomes of arterial pelvic embolization for intractable postpartum hemorrhage and particularly its effect on menses, fertility, and outcomes of subsequent pregnancies.

STUDY DESIGN

Fifty-six consecutive patients who underwent emergency pelvic arterial embolization for severe postpartum hemorrhage between April 1995 and July 2005 were included in the study. Patients were contacted to obtain information about menses and fertility after pelvic arterial embolization.

RESULTS

Thirty-four women (61.8%) were successfully contacted. One patient had a hysterectomy. Thirty women (91%) reported regular menses. Thirteen women (38.3%) had a total of 20 spontaneous pregnancies. Eight pregnancies ended during the first trimester. The 12 other pregnancies (60%) were all normal and all patients delivered vaginally healthy babies with normal weight for gestational age.

CONCLUSION

The current study suggests that fertility is not adversely affected by arterial pelvic embolization for intractable postpartum hemorrhage and that women can conceive after the procedure with normal pregnancy outcomes.

Ethanol embolotherapy of pelvic arteriovenous malformations: an initial experience

Objective

We retrospectively assessed the results of performing ethanol embolization for pelvis arteriovenous malformations (AVMs).

Materials and Methods

During the past 10 years, eight patients (8 females, age range: 27-52 years) with AVMs in the pelvic wall (n = 3) and uterus (n = 5) underwent staged ethanol embolizations (range: 1-5, mean: 2.5) under general anesthesia. Ethanol embolization was performed by the use of the transcatheter and/or direct puncture techniques. Clinical follow-up was performed for all of the patients, and imaging follow-up was available for seven patients. The therapeutic outcomes were established by evaluating the clinical outcome of the signs and symptoms, as well as the degree of devascularization observed on post-procedural angiography.

Results

During the 20 sessions of ethanol embolization, the solitary transarterial approach was used 14 times, the transvenous approach was used three times and direct puncture was used once. For two patients, the transarterial and transvenous or direct puncture approaches were used together in one session. For four patients, ethanol and coils were used as embolic agents, and n-butyl cyanoacrylate (NBCA) and ethanol were used in one patient. Seven (88%) of eight patients were cured of their AVMs and one patient (12%) displayed improvement. Major complications were seen in two patients (25%).

Conclusion

Ethanol embolization is effective for the treatment of pelvic arteriovenous malformations, though there is a chance of a major complication.

Amenorrhea and resumption of menstruation after uterine artery embolization for fibroids

OBJECTIVES

To determine whether women will experience permanent amenorrhea following uterine artery embolization for fibroids, and whether rates of onset differ in the long term according to age at the time of the procedure.

METHODS

Over 77 months, 211 consecutive eligible women were grouped by age (group A, <40 years [n=39]; group B, 40-44 years [n=98]; and group C, > or =45 years [n=74]) and the cumulative rates of onset of permanent amenorrhea were compared between the groups.

RESULTS

The likelihood of incurring permanent amenorrhea was significantly higher in group C. The cumulative rates in groups A, B, and C were 0%, 1.4%, and 19.7% at 3 years and 0%, 11.2%, and 40.4% at 6 years.

CONCLUSION

The rates of onset of permanent amenorrhea changed over time and differed according to age at the time of the procedure, with little likelihood of permanent amenorrhea at 6 years for women younger than 40 years at the time of the procedure.

Fertility after bilateral uterine artery embolization in a sheep model

OBJECTIVE

To evaluate the impact of bilateral uterine artery embolization (UAE) upon fertility in sheep.

DESIGN

Prospective study.

SETTING

University-based interventional radiology, pathology, and reproductive physiology units.

ANIMAL(S)

Nineteen control ewes, 10 ewes embolized with polyvinyl alcohol particles (PVA group), and 10 ewes embolized with Tris-acryl gelatin microspheres (TGMS group).

INTERVENTION(S)

Bilateral UAE was performed with 600- to 1,000-mum PVA particles or 700- to 900-mum TGMS particles. Animals of three groups were synchronized and naturally inseminated.

MAIN OUTCOME MEASURE(S)

For each ewe, a hormonal follow-up was performed throughout the gestation. Gestation duration, number and weight of newborns, and fertility and gestation rates were recorded.

RESULT(S)

Mean number of estrus before insemination and gestation duration were not different between groups. There were 47 living newborns: 26 control, 9 PVA, and 12 TGMS. Overall birth weight of newborns was 3.7 +/- 0.9 kg for controls, 3.6 +/- 1.1 kg for TGMS, and 2.2 +/- 0.7 kg for PVA (which was statistically significant vs. control). In the PVA group, there was a statistically significant decrease of fertility rate and gestation rate vs. controls, but this was not the case in the TGMS group.

CONCLUSION(S)

Particles of PVA decrease fertility in sheep and lead to intrauterine growth retardation.

Hysteroscopy after uterine fibroid embolization in women of fertile age

AIM

Uterine artery embolization for fibroids is a controversial issue for women with incomplete reproductive plans. Ovarian failure and uterine infection are the most dreaded complications of this procedure. The purpose of the present study was to assess the types and the frequency of intrauterine abnormalities and the histological features of the endometrium after embolization.

METHODS

Uterine artery embolization was performed on 51 women (average age 34.5 years) with intramural fibroid/s larger than 4 cm. Hysteroscopy and endometrial biopsy was performed from 3 to 9 months later in the luteal phase of the cycle.

RESULTS

Despite all women having no major symptoms prior to hysteroscopy, only 19 (37%) had completely normal hysteroscopic findings. There was intrauterine protrusion of fibroid/s in 19 cases (37%), yellowish coloration of the endometrium in 14 (28%), intrauterine or cervical adhesions in seven (14%), and communication between the myoma and the uterine cavity in five cases (10%). A normal, functional endometrium was histologically verified in 44 women of 49 (90%) who could be evaluated. Regressive changes (necrosis or hyalinization) of leiomyoma or of indefinite origin were found in 17 patients and embolization particles in five, including one patient with microspheres inside the endometrial vessel. No case of Asherman syndrome or endometrial atrophy was observed.

CONCLUSION

The frequency of abnormal hysteroscopic findings after embolization is surprisingly high. The clinical significance, reversibility, and impact on fertility of abnormal hysteroscopic findings after embolization remain unclear. Regardless, hysteroscopy should be strongly recommended to all patients after uterine fibroid embolization, prior to conception.

Uterine myomas: management

OBJECTIVE

To review the currently available literature regarding the current management alternatives available to women with uterine myomas.

DESIGN

Literature review of 198 articles pertaining to uterine myomas.

RESULT(S)

Many advances have been made in the management of uterine myomas. Watchful waiting; medical therapy; hysteroscopic myomectomy; endometrial ablation; laparoscopic myomectomy; abdominal myomectomy; abdominal, vaginal, and laparoscopic hysterectomy; uterine artery embolization; uterine artery occlusion; and focused ultrasound are now available.

CONCLUSION(S)

Many options are now available to women with uterine myomas. The presently available literature regarding the treatment of myomas is summarized.

Uterine artery embolization and future fertility potential

The growing body of evidence concerning the safety and efficacy of uterine artery embolization (UAE) has led to increasing confidence amongst gynecologists and interventional radiologists that UAE can be used safely to treat women with symptomatic fibroids. UAE is clearly preferable for certain subgroups of patients, for example those with increased risks of complications of general anesthesia, those with religious objection to blood transfusion and those wishing to avoid surgical risk. This review of the available literature demonstrates the paucity of information concerning safety and efficacy of UAE for those wishing to conceive. Case reports and series are largely positive. However, there are continuing concerns over the effects of UAE on ovarian and uterine function, and on subsequent pregnancy outcome. More long-term data and randomized controlled trials are required to address these issues. Women who undergo embolization should be told that the effects on pregnancy and the resulting child are uncertain and that there may be long-term implications for the health and development of the offspring. Hence, it is inadvisable to try to conceive following the procedure. Given the available evidence, concern must remain that UAE may lead to significant damage to fertility, with higher risk of miscarriage and adverse pregnancy outcome when compared with open or laparoscopic myomectomy.

Selective uterine artery embolization for management of interstitial ectopic pregnancy

Interstitial ectopic pregnancy is a rare condition of pregnancy and may be very dangerous if not identified and treated urgently. We report a case of successful treatment of an interstitial pregnancy using selective uterine artery embolization. A 27-year-old woman with interstitial pregnancy was treated by uterine artery embolization after failure of systemic methotrexate treatment. Her serum beta-human chorionic gonadotropin (β-hCG) was undetectable one month after the therapeutic embolization and transvaginal sonography 31 days after embolization showed normal endometrium and cornu. The patient achieved a normal pregnancy eight months after embolization.

Markers of muscle ischemia, necrosis, and inflammation following uterine artery embolization in the treatment of symptomatic uterine fibroids

OBJECTIVE

The objective of the study was to quantify markers of myometrial ischemia, necrosis, and inflammation in women undergoing uterine artery embolization (UAE).

STUDY DESIGN

Women with symptomatic fibroids were randomized to treatment with UAE (n = 14) or abdominal myomectomy (n = 11). Peripheral venous blood samples were taken before and after the procedure, at 24 hours and 6 weeks. Creatine kinase (CK) and ischemia-modified albumin (IMA) were measured as markers of necrosis and ischemia. Inflammation was assessed by measurement of C-reactive protein (CRP).

OUTCOME MEASURES

Changes in the markers following UAE and myomectomy were measured.

RESULTS

Following UAE, no change was seen in CK or IMA, but CRP was raised only at 6 weeks. At 24 hours after myomectomy, there were significant rises in all 3 markers, with a return to normal by 6 weeks.

CONCLUSION

No significant ischemia or necrosis occurs in the myometrium following UAE, whereas the delayed rise in CRP is likely to reflect necrosis in fibroids.

La chirurgie tubaire et utérine a-t-elle un effet délétère sur la fonction ovarienne?

Changes in menstrual pattern after tubal sterilisation have been reported for more than 50 years. Hence all tubal surgeries have been suspected of altering the ovarian reserve, by damage to the ovarian blood vessels. Recent studies showed that tubal surgery has no significant adverse effect on doppler flow indice and hormonal markers. Hysterectomy and uterine artery embolization seem to decrease ovarian reserve in perimenopausal women. Uterine artery embolization does not seem to have adverse effects on normally functioning ovaries.
