RESUMO
OBJECTIVE: To determine the effects of uterine artery embolization (UAE) on ovarian reserve as measured by Anti-Müllerian hormone (AMH) levels. MATERIAL AND METHODS: Non-randomized, observational study of 89 women 23-40 years of age who received UAE. Control hormone levels were measured prior to UAE and the first post-embolization measurement was taken at various times post-procedure (mean = 190 ± 229 days). RESULTS: Historical work verified by our earlier work has shown that AMH levels decline with age. Regression analysis allows us to determine whether UAE contributes to a greater decline in AMH values over that naturally occurring with aging. The effect of the procedure was found to contribute no deleterious effect to the natural decline in AMH levels. In addition, multiple blood draws were obtained from 32 patients up to 47 months post-UAE. Regression studies with these patients as their own controls showed no long-term diminishment of ovarian reserve due to the UAE procedure. CONCLUSIONS: Earlier reported data are consistent with larger sample size. UAE does not affect ovarian reserve in women <40 as evidenced by no significant change in AMH levels after embolization. Women who are of reproductive age and have uterine fibroids can consider UAE without concern for adverse effects on their fertility.

Uterine artery embolization (UAE) research has largely been focused on women over 40 years, yet women of reproductive age undergo UAE without any increased morbidity. Some physicians refrain from recommending UAE to women in this age group because of some research findings showing a negative effect on fertility. This review presents a comprehensive discussion of the fertility potential of women undergoing UAE, in terms of pregnancy rates and complications as well as ovarian function and reserve. Findings indicate many benefits for women desiring fertility who undergo UAE over traditional myomectomy.

OBJECTIVE: To evaluate the efficacy of abdominal myomectomy after uterine artery embolization (UAE-AM) among patients with myomas. METHODS: In a retrospective study, chart data were reviewed for patients attending a center in California, USA, who underwent UAE-AM between 1999 and 2012. Patients had been offered the combined procedure if the diameter of the myoma was at least 4cm, they wished to preserve fertility, or they were candidates for a traditional abdominal myomectomy. Estimated blood loss, fluoroscopy times, and hospital stay were recorded. Follow-up data on uterine volume and fibroid size had been collected via magnetic resonance imaging or ultrasonography approximately 3-6 months after UAE-AM. RESULT: Overall, 20 patients underwent UAE-AM. Approximately 6 months after the procedure, the mean decrease in uterine volume was 77.33%±14.25% and that in myoma diameter was 46.45%±25.61%. Six women subsequently became pregnant; one patient had two separate pregnancies. No patient required a conversion to hysterectomy or blood transfusion, and no recurrences were reported. CONCLUSION: UAE-AM was found to be an effective option available to women with large myomas who wished to preserve their uterus. With the combination procedure, patients had favorable outcomes with no fibroid recurrence.

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.

UNLABELLED: Objective: To evaluate the safety and efficacy of uterine artery embolization combined with endoscopic myomectomy. MATERIAL AND METHODS: We conducted a retrospective chart review of patients (n = 125) who underwent myomectomy concurrent with embolization within one month. We assessed two groups: 1) uterine artery embolization followed by hysteroscopic myomectomy and 2) uterine artery embolization followed by laparoscopic myomectomy. RESULTS: Following the combination procedures, 72% of the surveyed women reported symptom improvement. With the combined procedures, 92.5% of patients experienced reduction in myoma diameter and 87.5% of patients had decreased uterine size after an average of 4.70 months post subsequent procedure. The amount of decrease in the uterine volume (p = 0.39) and fibroid size (p = 0.23) were not significant between the two endoscopic myomectomy groups. CONCLUSIONS: Combining myomectomy with uterine artery embolization is a safe and effective procedure in treating symptoms and reducing myoma and uterine volumes.

OBJECTIVE: To evaluate the success rate of uterine artery embolization for leiomyomata for women under 40 years of age. MATERIAL AND METHODS: This observational study of fibroid treatment in women under 40 years of age at the time of procedure was conducted at a private practice located in Los Angeles, CA. One hundred and four patients participated in the study. The study involved a pre- and post- UAE survey of symptoms evaluated on a scale of mild, moderate, or severe. The post UAE assessment also involved an indication of whether the patients would recommend UAE. Patients were surveyed concerning subsequent pelvic surgery and pregnancy. RESULTS: Comparison of pre- and post- survey data resulted in an overall success rate of 90.4% based on relief of symptoms. Patients reported no late onset failures. Several patients underwent full-term pregnancies. 6.7 % of patients underwent abdominal myomectomy following UAE. No patient underwent hysterectomy. CONCLUSION: No significant difference exists in the success rate of UAE for women under 40 and the entire cohort of women undergoing UAE. UAE is a suitable form of treatment for women in this age group.

PURPOSE: To evaluate retrievability of the Celect vena cava filter over time and to assess the safety of the retrieval procedure in a prospective multicenter registry. MATERIALS AND METHODS: Between October 2005 and March 2008, Celect filters were placed in 95 patients (61 men; mean age, 51 years +/- 18.5) with a temporary need for an inferior vena cava (IVC) filter. All patients satisfied requirements for filter placement; the primary indications for placement were pulmonary embolism (PE) with a contraindication to or failure of anticoagulation (n = 40), high risk for further PE (n = 29), trauma (n = 23), or massive PE with residual deep vein thrombosis and risk for further PE (n = 3). Filter orientation, vena cava injury, and other device-related incidents were evaluated at implantation and retrieval. The degree of difficulty associated with retrieval was also assessed. RESULTS: Filter retrieval was attempted in 58 patients (mean indwell time of 179 days; median, 168.5 d; range, 5-466 d). Fifty-six filters (96.6%) were successfully retrieved. Unsuccessful retrieval attempts were attributed to filter tilt (n = 1) or excessive tissue growth with the hook embedded in the endothelium (n = 1). No adverse events were associated with the inability to retrieve these filters. A Kaplan-Meier product-limit survival estimate revealed that the probability of successful filter retrieval remained at 100% at 50 weeks and at more than 74% at 55 weeks after implantation. No adverse events were related to the retrieval procedures. CONCLUSIONS: Retrieval of the Celect filter was performed safely as long as 466 days after implantation.

PURPOSE: To evaluate the likelihood of successful retrieval of the Günther Tulip vena cava filter after various implant durations (up to 494 days). MATERIALS AND METHODS: Retrievable Günther Tulip filters were placed in 554 patients. All patients satisfied requirements for filter placement; the primary indication for placement was specified for 394 patients (71%), as follows: unspecified trauma (n = 164), bariatric procedures (n = 128), orthopedic procedures (n = 36), and other (n = 66). Filter tilt and vena cava injury were assessed at implantation. Filters were not repositioned after placement. At retrieval, filter orientation, vena cava injury, other device-related incidents, and the degree of difficulty associated with retrieval were reported. RESULTS: Filter retrieval was attempted in 275 patients and successful in 248 (90.2%). The mean filter indwell time was 58.9 days (range, 3-494 days). Unsuccessful retrievals (n = 27) were attributed primarily to improper hook orientation (n = 10) or excessive tissue in-growth at the filter legs (n = 16). Of the remaining 279 patients, 223 withdrew from the study, 41 were associated with a decision to keep the filter as a permanent device, 13 died for reasons unrelated to the study, and two had no reported endpoint data. A Kaplan-Meier product-limit survival estimate revealed that the probability of successful device retrieval remained greater than 94% at 12 weeks and greater than 67% at 26 weeks. CONCLUSIONS: This study contributes to the body of clinical data related to retrievable filters, demonstrating reliable retrieval rates at 12 weeks, with successful retrievals up to 17 months after implantation.

PURPOSE: To evaluate the safety and effectiveness of the Zilver vascular stent in the treatment of de novo or restenotic lesions in the external and common iliac arteries. MATERIALS AND METHODS: Regardless of the results of an initial percutaneous transluminal angioplasty (PTA), 151 consecutive patients were implanted with Zilver vascular stents (Cook, Bloomington, Ind) in up to two stenotic (< or =10 cm) or occluded (< or =5 cm) atherosclerotic lesions of the external or common iliac arteries. The primary endpoint was the rate of major adverse events within 9 months after the procedure. Major adverse events were defined as death, myocardial infarction, target lesion revascularization, and limb loss. Secondary endpoints included acute procedural success, 30-day clinical success, 9-month patency rate, 9-month functional status (on the basis of the validated Walking Impairment Questionnaire), and ankle-brachial index (ABI). RESULTS: of 1-, 6-, and 9-month follow-up are reported. Results The 9-month device and/or procedural-related major adverse event rate (adjudicated by an independent clinical events committee) was 2.7%. The all-cause major adverse event rate was 7.5%. Both rates were substantially below the prespecified objective performance criterion of 16%. The acute procedure success rate and 30-day clinical success rate were 98.0% and 94.0%, respectively. The 9-month patency rate, measured with duplex ultrasonography, was 92.9%. Significant improvement in the ABI and walking distance and walking speed scores, relative to preprocedural values, was seen at 1 month and was maintained through 9-month follow-up. CONCLUSIONS: The Zilver vascular stent is safe and effective as an adjunct to PTA in the treatment of symptomatic disease of the iliac arteries.

The investigators examined 326 pairs of angiograms from 2 randomized dose-finding (0.2 to 3.1 microg paclitaxel/mm(2) of stent surface area) clinical trials of polymer-free paclitaxel-eluting stents in de novo lesions (the ASian Paclitaxel-Eluting stent Clinical Trial [ASPECT] and the European evaLUation of Taxol Eluting Stent [ELUTES]). A dose-dependent effect was observed: the largest dose of paclitaxel in the 2 trials resulted in a significantly larger proportion of lesions at follow-up with <10% diameter stenosis (54% vs 16%, p = 0.00012 in ASPECT; 53% vs 21%, p = 0.013 in ELUTES) and with minimal luminal diameter located outside the stent compared with control stents (62% vs 20% in ASPECT, 48% vs 18% in ELUTES; p <0.05). Also, significantly shorter lesion lengths at 6-month follow-up were observed for the doses of 0.7 to 3.1 microg/mm(2) (p <0.03) relative to their respective lengths before the procedure compared with control stents.
