Campbell WA, Chick JFB, Shin DS, Makary MS. Value of interventional radiology and their contributions to modern medical systems. FRONTIERS IN RADIOLOGY 2024; 4:1403761. [PMID: 39086502 PMCID: PMC11288872 DOI: 10.3389/fradi.2024.1403761] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Accepted: 06/25/2024] [Indexed: 08/02/2024]
Abstract
Interventional radiology (IR) is a unique specialty that incorporates a diverse set of skills ranging from imaging, procedures, consultation, and patient management. Understanding how IR generates value to the healthcare system is important to review from various perspectives. IR specialists need to understand how to meet demands from various stakeholders to expand their practice improving patient care. Thus, this review discusses the domains of value contributed to medical systems and outlines the parameters of success. IR benefits five distinct parties: patients, practitioners, payers, employers, and innovators. Value to patients and providers is delivered through a wide set of diagnostic and therapeutic interventions. Payers and hospital systems financially benefit from the reduced cost in medical management secondary to fast patient recovery, outpatient procedures, fewer complications, and the prestige of offering diverse expertise for complex patients. Lastly, IR is a field of rapid innovation implementing new procedural technology and techniques. Overall, IR must actively advocate for further growth and influence in the medical field as their value continues to expand in multiple domains. Despite being a nascent specialty, IR has become indispensable to modern medical practice.

Abstract
Image-guided solid tumor ablation methods have significantly advanced in their capability to target primary and metastatic tumors. These techniques involve noninvasive or percutaneous insertion of applicators to induce thermal, electrochemical, or mechanical stress on malignant tissue to cause tissue destruction and apoptosis of the tumor margins. Ablation offers substantially lower risks compared to traditional methods. Benefits include shorter recovery periods, reduced bleeding, and greater preservation of organ parenchyma compared to surgical intervention. Due to the reduced morbidity and mortality, image-guided tumor ablation offers new opportunities for treatment in cancer patients who are not candidates for resection. Currently, image-guided ablation techniques are utilized for treating primary and metastatic tumors in various organs with both curative and palliative intent, including the liver, pancreas, kidneys, thyroid, parathyroid, prostate, lung, breast, bone, and soft tissue. The invention of new equipment and techniques is expanding the criteria of eligible patients for therapy, as now larger and more high-risk tumors near critical structures can be ablated. This article provides an overview of the different imaging modalities, noninvasive, and percutaneous ablation techniques available and discusses their applications and associated complications across various organs.

Abstract
OBJECTIVE To conduct a systematic review to evaluate the effect of procedural interventions for leiomyomas on pelvic floor symptoms. DATA SOURCES PubMed, EMBASE, and ClinicalTrials.gov were searched from inception to January 12, 2023, searching for leiomyoma procedures and pelvic floor disorders and symptoms, restricted to primary study designs in humans. METHODS OF STUDY SELECTION Double independent screening for studies of any study design in all languages that reported pelvic floor symptoms before and after surgical (hysterectomy, myomectomy, radiofrequency volumetric thermal ablation) or radiologic (uterine artery embolization, magnetic resonance-guided focused ultrasonography, high-intensity focused ultrasonography) procedures for management of uterine leiomyomas. Data were extracted, with risk-of-bias assessment and review by a second researcher. Random effects model meta-analyses were conducted, as feasible. TABULATION, INTEGRATION, AND RESULTS Six randomized controlled trials, one nonrandomized comparative study, and 25 single-group studies met criteria. The overall quality of the studies was moderate. Only six studies, reporting various outcomes, directly compared two procedures for leiomyomas. Across studies, leiomyoma procedures were associated with decreased symptom distress per the UDI-6 (Urinary Distress Inventory, Short Form) (summary mean change -18.7, 95% CI -25.9 to -11.5; six studies) and improved quality of life per the IIQ-7 (Incontinence Impact Questionnaire, Short Form) (summary mean change -10.7, 95% CI -15.8 to -5.6; six studies). There was a wide range of resolution of urinary symptoms after procedural interventions (7.6-100%), and this varied over time. Urinary symptoms improved in 19.0-87.5% of patients, and the definitions for improvement varied between studies. Bowel symptoms were inconsistently reported in the literature. CONCLUSION Urinary symptoms improved after procedural interventions for uterine leiomyomas, although there is high heterogeneity among studies and few data on long-term outcomes or comparing different procedures.

Abstract
Objectives: Fibroids cause significant morbidity and are the most common indication for hysterectomies worldwide, delimiting a major public health problem. Uterine artery embolization (UAE) is an alternative therapy to surgical treatment of symptomatic fibroids; it has satisfactory long-time results and is no longer considered investigational for the treatment of symptomatic fibroids. This study was undertaken to evaluate changes in fibroid specific symptom severity and health-related quality of life (HRQOL) after UAE and to optimize the assessment of safety and outcomes measures for participants who receive UAE to objective compare UAE and surgical alternatives for therapy of symptomatic fibroids. Study design: The analysis was based on questionnaires completed by 270 pre-menopausal females with a mean age of 42 years (range, 38-50 years) who underwent UAE for uterine leiomyomas and/or adenomyosis from November 2013 through December 2019. Only symptomatic women were selected whose symptoms were not improving with medication and who did not wish to have children. The primary outcome measure was a change in fibroid symptoms and HRQOL (health related quality of life) after UAE. Secondary outcomes included the decrease in uterine volume after UAE. Results: Questionnaires were completed by 270 women (100%) at a mean of 12.1 months from UAE. The median follow-up period was two years. Uterine fibroid embolization led to a shrinkage at three months for the 90% of the participants. A reduction of bleeding symptoms, pain and bulk-related symptoms was observed in 89.7%, 88.9%, and 89.5% of the patients, respectively. In the long term, there was no significant difference in parameters assessed compared with the midterm follow-up findings. A total of 6 patients (2.3%) underwent fractional curettage an average of 32.1 months after intervention due to necrotic changes in submucosal fibroids. All participants continued to be satisfied with the intervention, and 240 patients (88.9%) answered that they would recommend uterine fibroid embolization to other patients. Conclusions: Women who undergo UAE have a significant decrease in symptom severity and increase in HRQOL which is associated with high levels of satisfaction with the procedure (even when subsequent therapies are pursued).

Abstract
Females with symptomatic leiomyomas (fibroids) wishing to maintain fertility are faced with difficult treatment choices. These include uterine fibroid embolization (UFE), myomectomy, hormonal therapy, MRI high intensity focused ultrasound, and myolysis. This review focuses on UFE, one of the most commonly accepted minimally invasive procedural choices among patients with symptomatic fibroids wishing to retain the option of becoming pregnant in the future, and makes comparisons to myomectomy which has historically been the surgical choice for fertility-preserving fibroid treatment. Pubmed and Google Scholar searches using keywords such as: uterine artery embolization, uterine fibroid embolization, pregnancy, complications, infertility were performed between Jan 1, 2019 and May 10, 2019. Publications were chosen based on their inclusion of information pertaining to fertility or pregnancy after UFE without being limited to single case reports.Randomized controlled trials comparing myomectomy and UFE are limited due to study size and confounding variables, but through registry data and familiarity with referring clinicians, UFE has gained wide acceptance. Healthy pregnancies following UFE have been sporadically reported but the actual fertility rate after UFE remains uncertain. Conversely, low birth weight, miscarriage and prematurity have been associated with UFE. Despite inherent risks of possible fertility issues after UFE, the procedure remains an option for females with clinically symptomatic fibroids who desire pregnancy. However, additional research regarding rates of conception and obstetrical risks of infertility following UFE is necessary.

Abstract
Uterine fibroids, also known as leiomyomas, are the most common benign tumor in women of reproductive age. When symptomatic, these patients can present with bleeding and/or bulk-related symptoms. Treatment options for symptomatic uterine leiomyomas include medical management, minimally invasive treatment such as uterine artery embolization, and surgical options, such as myomectomy. It is important to understand the role of these treatment options in various clinical scenarios so that appropriate consultation is performed. Furthermore, patients should be presented with the outcomes and complications of each of these treatment options. A summary of the data and clinical trials of the treatment options for symptomatic uterine leiomyomas is outlined in this article. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
Uterine fibroids occur in approximately 50% of women over the age of 40 years, and an estimated 50% of those are symptomatic. Menorrhagia is the most common symptom and the primary indication for treatment, although bulk symptoms often occur and can be treated. Pharmacotherapy is typically inadequate unless it can be expected to successfully bridge to menopause or allow for a less-invasive intervention. However, hormonal therapies have risks. Hysterectomy is still the most commonly performed procedure for symptomatic fibroids and has the lowest rate of reintervention (compared with myomectomy or uterine artery embolization [UAE]), but rates of more serious complications are higher and patient satisfaction and ability to return to normal activities may also be less favorable. Myomectomy is not necessarily less morbid than hysterectomy and may have a greater failure rate than UAE. Techniques and devices vary with little standardization, and operator experience is crucial to success. The largest studies of UAE show very low rates of serious complications and rapid recovery. UAE significantly improves symptoms related to uterine fibroids in 85%-90% of patients. Herein, this article will discuss the nature of fibroids and their diagnosis, pharmacotherapy, surgical treatment, and nonsurgical interventional treatment, including UAE and magnetic resonance-guided focused ultrasound.

Abstract
PURPOSE This study was designed to evaluate the long-term clinical outcome and frequency of reinterventions in patients with uterine fibroids treated with embolization at a single center using polyvinyl alcohol microparticles. METHODS The study included all patients with symptomatic uterine fibroids treated with uterine fibroid embolization (UFE) with spherical (s-PVA) and nonspherical (ns-PVA) polyvinyl alcohol microparticles during the period January 2001 to January 2011. Clinical success and secondary interventions were examined. Hospital records were reviewed during follow-up, and symptom-specific questionnaires were sent to all patients. RESULTS In total, 515 patients were treated with UFE and 350 patients (67 %) were available for long-term clinical follow-up. Median time of follow-up was 93 (range 76-120.2) months. Eighty-five patients (72 %) had no reinterventions during follow-up in the group embolized with ns-PVA compared with 134 patients (58 %) treated with s-PVA. Thirty-three patients (28 %) underwent secondary interventions in the ns-PVA group compared with 98 patients (42 %) in s-PVA group (χ(2) test, p < 0.01). CONCLUSIONS Spherical PVA particles 500-700 µm showed high reintervention rate at long-term follow-up, and almost one quarter of the patients underwent secondary interventions, suggesting that this type of particle is inappropriate for UFE.

Abstract
Strong evidence for both safety and effectiveness of uterine fibroid embolization has been generated since the procedure's introduction. This review will focus on the key articles representing the best evidence to summarize the outcomes from uterine embolization. This review will attempt to answer three important questions associated with uterine embolization. First, does uterine embolization relieve symptoms caused by uterine fibroids? Second, how well does the improvement in symptoms and quality of life after uterine embolization compare with standard surgical options for fibroids? Finally, how durable is the improvement in fibroid-related symptoms and quality of life after embolization?

Abstract
OBJECTIVE To evaluate the effectiveness of uterine-sparing interventions for women with symptomatic uterine fibroids who wish to preserve their uterus. DESIGN Systematic review and indirect comparison meta-analysis. METHODS MEDLINE, EMBASE, CENTRAL, conference proceedings, trial registers and reference lists were searched up to October 2013 for randomized controlled trials. MAIN OUTCOME MEASURES Outcome measures were patient satisfaction, re-intervention and complications rates, reproductive outcomes, and hospitalization and recovery times. RESULTS Five trials, involving 436 women were included; two compared uterine artery embolization with myomectomy and three compared uterine artery embolization with laparoscopic uterine artery occlusion. Indirect treatment comparison showed that myomectomy and uterine artery embolization resulted in higher rates of patient satisfaction (odds ratio 2.56, 95% credible interval 0.56-11.75 and 2.7, 95% credible interval 1.1-7.14, respectively) and lower rates of clinical failure (odds ratio 0.29, 95% credible interval 0.06-1.46 and 0.37, 95% credible interval 0.13-0.93, respectively) than laparoscopic uterine artery occlusion. Myomectomy resulted in lower re-intervention rate than uterine artery embolization (odds ratio 0.08, 95% credible interval 0.02-0.27) and laparoscopic uterine artery occlusion (odds ratio 0.08, 95% credible interval 0.01-0.37) even though the latter techniques had an advantage over myomectomy because of shorter hospitalization and quicker recovery. There was no evidence of difference between the three techniques in ovarian failure and complications rates. The evidence for reproductive outcomes is poor. CONCLUSION Our study's results suggest that laparoscopic uterine artery occlusion is less effective than uterine artery embolization and myomectomy in treatment of symptomatic fibroids. The choice between uterine artery embolization and myomectomy should be based on individuals' expectations and fully informed discussion.

Abstract
Uterine fibroids are the most common solid tumors found in women of reproductive age. It has been reported that deregulation of the mammalian target of rapamycin (mTOR) pathway plays an important role in the etiology of leiomyoma. Here, we investigated the effect of rapamycin, an inhibitor of mTORC1, on the growth of primary fibroid smooth muscle cells (fSMCs) and human telomerase reverse transcriptase (hTERT)-transduced and immortalized fSMCs. With the primary fSMCs, a 24-hour treatment with rapamycin was sufficient to trigger a growth arrest that was not reversible upon drug removal. By contrast, the growth inhibitory effect of rapamycin on the hTERT-transduced fSMCs was readily reversible, as these cells resumed proliferation upon the withdrawal of the drug. These results suggest that rapamycin-induced irreversible growth arrest of fSMCs is dependent on the senescence barrier that is abrogated by the ectopic expression of telomerase.

Abstract
PURPOSE To assess the efficacy of two embolic agents in the treatment of symptomatic uterine leiomyomas. MATERIALS AND METHODS A randomized, prospective, single-center study enrolled 60 women with symptomatic uterine leiomyomas. Uterine artery embolization (UAE) with spherical polyvinyl alcohol (SPVA) microspheres (n = 30; 700-900 μm and 900-1,200 μm; near-stasis or stasis endpoint) and tris-acryl gelatin (TAG) microspheres (n = 30; 500-700 μm; "pruned-tree" endpoint) was performed. Infarction rates were calculated for the dominant tumor and for small (< 2 cm) and large (> 2 cm) nondominant tumors. The primary endpoint was tumor infarction at 24 hours measured by contrast-enhanced magnetic resonance imaging assessed by a blinded reviewer. RESULTS Baseline characteristics were similar between groups. The primary endpoint was similar in both treatments (≥ 91% dominant tumor infarction; SPVA. 86.2%; TAG, 93.3%, P = .35). Complete infarction (100%) was also similar between arms at 24 hours and 3 months. Symptom severity was reduced and quality of life improved equally at 3 and 12 months in each treatment group. Complications were minor in both groups. CONCLUSIONS Uterine leiomyoma infarction at 24 hours and 3 months after treatment with SPVA or TAG microspheres was comparable when using near-stasis as a procedural endpoint with SPVA microspheres. Symptom relief was maintained for as long as 12 months for both embolic agents.

Abstract
Myoma treatment by uterine artery embolisation (UAE) using non-spherical PVA particles or calibrated tris-acryl microspheres>500μm is effective in more than 90 % of cases in the short-term. In the long-term, menorrhagia, bulk-related symptoms and pelvic pain are significantly improved or eliminated in 75 % of cases at 5 to 7 years. At 6 months, uterine volume reduction and larger myoma volume reduction varies between 30 to 60 % and 50 to 80 % respectively. During hospital stay the complication rate is very low, less than 3 % mostly urinary infection and pain. Secondary hysterectomy for complication is less than 2 % at 3 months. Definitive amenorrhea is reported in less than 5 % of cases in women of more than 45-year of age. No significant impact of embolization on hormonal function has been reported in women less than 45 years with normal baseline function. UAE is not indicated for submucous myomas. Randomized studies comparing embolization to hysterectomy demonstrate that reinterventions are more frequently performed after embolization. Secondary hysterectomy is performed in 13 to 24 % of cases at 2 years and in up to 28 % of cases at 5 years. Hospital stay, duration of recovery and time off work are shorter after embolization compared to hysterectomy. Embolization is cheaper than hysterectomy at 12 and 24 months even taking into consideration the additional costs of imaging and reinterventions. UAE is a good alternative treatment in women with unique myoma of less than 10cm and multiple myomas around 15cm. This treatment should be proposed to women each time possible. Randomized studies comparing embolization to myomectomy demonstrate that in the short and mid-term there is no difference in terms of control of menorrhagia and bulk-related symptoms. Uterine volume reduction and quality of life were not different at 6 months. Periprocedural and 30-day complication rates are not different. At 6 months, the rate of complications is higher after myomectomy. Reinterventions are more frequent after embolization compared to myomectomy. Hospital stay, duration of recovery and time off work are shorter after embolization compared to myomectomy. UAE is less aggressive than myomectomy and should be proposed as a conservative alternative treatment. Embolization should be considered with caution in pregnancy-seeking women since there is still a lack of good quality data available in the specific group of patients. FSH level is more frequently elevated after embolization compared to myomectomy. Pregnancy rate and term pregnancy rate are higher after myomectomy compared to embolization. Spontaneous abortion is more frequent after embolization than after myomectomy. At this time, UAE is not indicated excepted in studies or in specific cases when the woman want a pregnancy. Embolization performed before myomectomy (preoperative or combined procedures) can be discussed for an individual patient but there is not enough data to support its routine use.

Abstract
PURPOSE To evaluate long-term clinical efficacy of uterine artery embolization (UAE) for uterine fibroids with respect to symptom control and improvement in quality of life. MATERIALS AND METHODS Between October 2000 and October 2007, 380 consecutive women underwent UAE. To determine long-term efficacy, the rate of reinterventions (ie, repeat UAE, hysterectomy, myomectomy) and the clinical response regarding symptoms related to bleeding and bulk were documented. Persistence, worsening, or recurrence of symptoms and reinterventions were classified as treatment failure (TF). The cumulative rate of freedom from TF was determined by Kaplan-Meier analysis. Cox regression was used to identify possible clinical or morphologic predictors of outcome. Secondary outcome measures were changes in disease-specific quality of life and onset of menopause. RESULTS Follow-up was available for a median of 5.7 years (range, 3.1-10.1 y) after treatment in 304 of 380 (80%) patients. There were 54 TFs with subsequent reintervention in 46 women. Kaplan-Meier analysis revealed a cumulative TF rate of 23.3% after 10 years. Cox regression demonstrated a significantly higher likelihood of TF in patients<40 years old compared with patients>45 years old (hazard ratio, 2.28; P = .049). Women without TF showed sustained normalization of disease-specific quality of life (P <.001). Cessation of menstruation at a median age of 51 years was reported by 57 (22.8%) of 250 women. CONCLUSIONS UAE leads to long-term control of fibroid-related symptoms and normalization of quality of life in approximately 75% of patients. Younger women seem to have a higher risk of TF than older women closer to menopause.

Abstract
Leiomyomas (or fibroids) are exceedingly common lesions. The indications to initiate treatment are based on the symptoms that can arise from their presence. In general, medical therapy should be considered the first line of treatment. Currently, the treatment of fibroids is in evolution. Since uterine artery embolization (UAE) was first described by Ravina et al in 1995, it has been shown to be a safe, efficacious, and cost-effective alternative to traditional surgical options, with data from long-term studies now available. Appropriate patient evaluation and selection are vital; the ideal candidate is one who is premenopausal, has symptomatic fibroids resistant to medical therapy, no longer desires fertility, and wishes to maintain her uterus. Uterine artery embolization is primarily an angiographic procedure, but periprocedural clinical management is critical for patient satisfaction. This article discusses the various embolic materials that are commonly used and available for UAE; understanding the technical nuances is critical for long-term success.

Abstract
Uterine artery embolization (UAE) evolved as a treatment for symptomatic uterine fibroids in the early 1990s, after initially being used as a temporizing measure prior to hysterectomy or myomectomy. Since that time, over 100,000 UAEs have been performed. Technical success rates have been quoted ranging from 94 to 99%. The overall incidence of major complications associated with the procedure is low, the majority of which can be prevented. Knowledge of the potential complications and the measures that can be taken to avoid these complications is essential. Furthermore, because UAE is a relatively new procedure, no standardized recommendations for patient follow-up exist. Common practice for patient follow-up includes both clinic visits at increasing time intervals postprocedure, as well as telephone follow-up, and imaging follow-up when necessary. As symptomatic improvement is subjective, some institutions have developed standardized questionnaires to better assess patient improvement postprocedure. Aggressive pain control is a crucial component of follow-up, as uncontrolled pain can result in readmission and patient dissatisfaction.

Abstract
PURPOSE To evaluate safety and efficacy of uterine artery embolization using narrow-size-range polyphosphazene-coated hydrogel microspheres (Embozene, CeloNova Biosciences, Newnan, GA). METHODS Between May 2006 and September 2008, a total of 121 consecutive patients (mean ± SD age 42.1 ± 5.4 years, range 30.5-51.5 years) were enrolled onto this single-center study. The primary study endpoint was safety as assessed by the society of interventional radiology (SIR) classification. The secondary endpoint was efficacy, which was based on a 1-year magnetic resonance imaging study and relief of symptoms documented by the Medical Outcomes Study 36-Item Short-Form Health Survey questionnaire over a 2-year interval. RESULTS The mean ± SD diameter of the dominant fibroid was 6.4 ± 2.6 (range, 2.9-13.9) cm and the mean volume 137.2 ± 245.1 (range, 5.3-1184) ml. Most patients had multiple fibroids with 11% more than 10. A total of 240 of 242 interventions were completed as planned, a technical success rate of 99.2%. According to the SIR classification, one type A, eight type C, and one type D complication occurred. Total devascularization was noted in 96% (116 of 121) of dominant fibroids. Volume decrease was 4% at 2 weeks, 52% (P < 0.001) at 3 months, 78% (P < 0.001) at 6 months, and 91% at 12 months (P < 0.001). The latter difference was statistically significant (P = 0.007). A total of 92% had improved hypermenorrhea at 1 year and 94% at 2 years. Dysmenorrhea was improved in 96% at 1 year and in 95% at 2 years. The overall health status score was 60.4 ± 26.2 points at baseline and 96.9 ± 3.8 after 1 year (P = 0.0019). CONCLUSION Uterine artery embolization with Embozene microspheres is a safe procedure. Its efficacy is demonstrated by high fibroid devascularization and volume reduction rates and significant improvements of clinical symptoms and quality-of-life scores during follow-up.

Abstract
PURPOSE This multicenter prospective study was conducted to evaluate the safety and the efficacy of uterine artery embolization (UAE) with gelatin sponge for symptomatic leiomyomas. MATERIALS AND METHODS Patients with symptomatic uterine leiomyomas were enrolled and treated with UAE. In phase I, nine patients were evaluated for safety. In phase II, 24 patients were accrued, and an intent-to-treat analysis was performed on all 33 patients. The primary endpoint was safety. Secondary endpoints included technical success, hospital stay, change in symptoms, leiomyoma volume on magnetic resonance (MR) imaging, and incidence of treatment failure. RESULTS UAE procedures were performed for all 33 patients. Two patients were lost to follow-up at 3 and 12 months. The median follow-up period was 33.4 months. Minor adverse events (AEs) occurred in 10 patients (33%); major AEs of permanent amenorrhea and leiomyoma expulsion occurred in two (6%). The most common AE was transient amenorrhea. Technical success was achieved in all patients. The median hospital stay was 5 days. At 12 months after UAE, menorrhagia had improved in 90% of patients, pelvic pain in 78%, and bulk-related symptoms in 97%. The mean reduction in leiomyoma volume on MR imaging at 12 months was 61%. Treatment failure occurred in one patient, who underwent hysterectomy for recurrent menorrhagia at 21 months. CONCLUSIONS UAE with gelatin sponge is safe, with efficacy comparable to other embolic agents based on published data. Gelatin sponge should be an option for UAE, but a prospective comparison versus other standard UAE embolic agents may be warranted.

Uterine artery embolization with trisacryl gelatin microspheres in women treated for leiomyomas: a clinicopathologic analysis of alterations in gynecologic surgical specimens.

Abstract
To characterize the histologic range of alterations due to uterine artery embolization with trisacryl gelatin microspheres in gynecologic specimens containing leiomyomas in detail, we report our clinicopathologic experience with 26 cases (longest postuterine artery embolization interval, 1.9 yr). Microspheres were observed in 85% of cases and could be seen up to 1.9 years after embolization. They were mainly present in leiomyomas and nonneoplastic myometrium but could be found in other nontargeted sites, such as the cervix, endometrium, ovaries, and fallopian tubes; however, infarction (present in 96% of cases) was confined to leiomyomas and did not involve other nonneoplastic tissues. The appearance of the infarcts was correlated with time after embolization, and coagulative necrosis/necrosis of indeterminate type was restricted to the early period after uterine artery embolization (before 10 wk postuterine artery embolization) whereas hyaline necrosis was seen predominantly in the late period (mostly after 10 wk, up to 1.9 yr). Of the 14 hysterectomy specimens with microspheres in extravascular spaces (almost all of which were in close proximity to the arteries), pseudoaneurysms were also focally present in 8 (57%) specimens. Microspheres were usually associated with mild inflammatory reactions, which persisted >1 year after embolization but did not become more severe over time. Morphologic and histochemical features of trisacryl gelatin microspheres were compared with other embolization agents, which can also be encountered in surgical specimens [polyvinyl alcohol (PVA) particles and PVA microspheres]. Trisacryl gelatin microspheres were negative with periodic acid-Schiff and orange-pink with Movat stains whereas PVA was positive with periodic acid-Schiff and black with Movat. Our study, the largest histologic analysis to date, confirms and extends the observations of earlier studies of trisacryl gelatin microspheres. In addition, we conclude that, as expected, the histologic appearance of microsphere-induced infarcts is a function of time, similar to healing of infarcts in nongynecologic sites. Pseudoaneurysms are a likely mechanism for the production of microspheres in extravascular spaces. Inflammation associated with microspheres can persist in gynecologic tissues but does not seem to result in the destruction of nontargeted sites. Finally, trisacryl gelatin microspheres can be distinguished from PVA particles and PVA microspheres based on a combination of morphologic features and histochemical stains.

Abstract
PURPOSE To assess long-term clinical effectiveness of uterine artery embolization (UAE) compared with abdominal myomectomy. MATERIALS AND METHODS Women who received UAE (n = 87) or abdominal myomectomy (n = 98) for symptomatic uterine leiomyomata between 2000 and 2002 at a single institution were consecutively enrolled in this study. Patients whose procedures were performed within 5 years before the study were included. Symptom evaluations with symptom severity scores, pregnancy rates, and satisfaction with the procedures were obtained via institutional review board-approved questionnaires. Chart reviews were performed to supplement analyses. RESULTS The retrospective cohort included 185 patients, of whom long-term follow-up was completed by 89 patients (48.1%), 48 being treated with UAE, and 41 with myomectomy. Follow-up ranged from 50 to 83 months. A higher but not statistically significant number of patients received repeat interventions after abdominal myomectomy (14%) versus UAE (8%; P = .204). Significantly higher symptom severity score improvements were seen in patients treated with UAE versus abdominal myomectomy (34 vs 31; P = .02). UAE recipients were less likely to attempt to get pregnant (P = .02), but those who did had a 66.7% success rate compared with 58.8% for patients who underwent myomectomy. Similar numbers of patients between groups were satisfied with the procedure (P = .57), reported effectiveness of symptom relief (P = .43), and would recommend the procedure to others (P = .37). CONCLUSIONS UAE results in long-term clinical success with outcomes comparable or superior to those of abdominal myomectomy.

Abstract
Benign uterine fibroids, or leiomyomas, are the most common tumors found in gynecologic practice. Symptomatic fibroids present with menorrhagia, pelvic pain, leukorrhea, pressure and bloating, increased abdominal girth, and severe dysmenorrhea. Traditional treatment has relied on surgery because long-term medical therapies have demonstrated only minimal response. Uterine fibroid embolization (UFE) using particulate emboli to occlude the uterine arteries, thereby disrupting the blood supply to fibroids and leading to devascularization and infarction, has been reported to be effective in alleviating fibroid-related symptoms. UFE is a safe, effective, and durable nonsurgical alternative to hysterectomy.

Abstract
Uterine fibroids, the most common benign tumors of the female reproductive system, are the most common indication for hysterectomy. However, this procedure is not the ideal treatment for many women including those who desire to preserve their fertility or simply do not want to undergo surgery. New technologies and surgical innovation provide treatments that are less associated with morbidity such as uterine artery embolization, magnetic resonance imaging-guided focused ultrasound, and laparoscopic uterine artery occlusion. This manuscript will discuss the putative mechanism of action and clinical application of uterine artery occlusion using Doppler-guided Uterine Artery Occlusion, a new investigational treatment modality for uterine fibroids.

Abstract
Background A number of noninvasive alternatives to hysterectomy have become available as treatments for uterine fibroids. These alternative therapies, however, may not relieve all symptoms. Consequently, the need for patient-reported outcomes to assess symptom reduction of uterine fibroids has become increasingly important to evaluate the clinical success of patients who choose these alternative therapies. The purpose of the study was to examine the responsiveness of the Uterine Fibroid Symptom and Health-Related Quality of Life Questionnaire (UFS-QOL) with treatment of uterine fibroids. Methods The responsiveness of the UFS-QOL was assessed as a post-hoc analysis of patients treated with MRI-guided focused ultrasound thermal ablation (MRgFUS) for uterine fibroids. The UFS-QOL and SF-36 were completed at baseline and months 1, 3, and 6. Patient perceived overall treatment effect (OTE) was assessed at month 3, while satisfaction with treatment was collected at month 6. The responsiveness of the UFS-QOL was examined using effect sizes and change scores by patient-reported overall treatment effect and satisfaction. Results A total of 102 women with complete UFS-QOL data were included in the analysis; the mean age was 45 years and 79% were Caucasian. From baseline to 6 months, significant improvements were observed in UFS-QOL Symptom Severity and all Health-Related Quality of Life (HRQL) subscale scores (p < 0.0001). When examining change in general health status over the 6-month follow-up period, significant improvements were noted in all 8 SF-36 subscales. The UFS-QOL was highly responsive with subscale effect sizes ranging from 0.74 for Sexual Function to -1.9 for Symptom Severity. Improvements in UFS-QOL subscales were associated with patient perceptions of perceived benefit and treatment satisfaction. Conclusion The UFS-QOL is responsive to treatment for uterine fibroids and is a useful outcome measure for uterine-sparing uterine fibroid treatments.

Abstract
Postembolization syndrome (PES) after transcatheter uterine artery embolization (UAE) is classically described as including self-limited pain, nausea, vomiting, and fever. However, the expected components of PES after UAE might also include leukocytosis, the incidence and magnitude of which have not yet been determined. A retrospective review of 78 patients who underwent elective UAE for symptomatic leiomyomas showed an increase in white blood cell (WBC) counts within 24 hours after the procedure in 86% of patients, with clinically defined leukocytosis (WBC count >11,000/microL) present in 21% of patients. Interventional radiologists and other clinicians involved in the care of these patients should expect such changes and not be alarmed regarding early infectious complications.

Abstract
PURPOSE To determine the degree of leiomyoma infarction after uterine artery embolization (UAE) performed with tris-acryl gelatin microspheres or polyvinyl alcohol (PVA) microspheres. MATERIALS AND METHODS Patients determined to be candidates and scheduled for UAE were randomized prospectively to receive tris-acryl gelatin microspheres or PVA microspheres. The manufacturers' recommended technique was used for both products during the UAE procedures (including the recently described refined protocol for PVA microspheres). All patients underwent magnetic resonance (MR) imaging of the pelvis with contrast agent enhancement before and after the UAE procedure. On the postprocedural MR study, the degree of tumor infarction was assessed on postcontrast images. These findings were classified as follows: 100% infarction, 90%-99% infarction, 50%-89% infarction, and less than 50% infarction. Treatment failure was defined by enhancement of more than 10% of a patient's entire tumor burden. RESULTS A total of 53 patients were enrolled in this study. Twenty-seven (mean age, 44.9 years) received PVA microspheres and 26 (mean age, 45.1 years) received tris-acryl gelatin microspheres. There were no significant differences in the preprocedural uterine volume, dominant tumor volume, location of dominant tumor, and presenting symptoms between populations. In the PVA microsphere group, treatment failure was seen in eight patients (29.6%). In the tris-acryl gelatin microsphere group, treatment failure was seen in one patient (3.8%), which was a significant difference between groups (P < or = .025). CONCLUSIONS There was a significantly greater degree of tumor infarction in patients treated with tris-acryl gelatin microspheres during UAE than in patients who received PVA microspheres administered in accordance with a newly refined protocol. Given the known risk of recurrence in patients with persistent tumor enhancement after UAE, it is concluded that tris-acryl gelatin microspheres should be the preferred agent for UAE at this time.

Abstract
OBJECTIVE The objective of the study was to describe a clinically useful factors index predicting long-term efficacy of uterine artery embolization (UAE). STUDY DESIGN Newly diagnosed patients with uterine leiomyoma wishing to retain their uterus underwent UAE at our institution. Clinical demographics and 4 prognostic factors were recovered from the medical record. A regrowth-free interval (RFI) was calculated for all patients based on leiomyoma regrowth or recurrence of any previously reported symptoms. RFI by prognostic factor was analyzed by the Kaplan-Meier method. RESULTS Forty-three patients were identified. Two prognostic factors were identified by multivariate analysis: vascularity (dichotomized as hypervascular vs hypovascular; RFI at 2 years, 80% vs 20%, P = .001) and number of nodules (solitary vs multiple; RFI at 2 years, 72% vs 25% at 2 years, P = .001) CONCLUSION UAE success may be predicted by 2 preoperative parameters. Further investigation is warranted.

Abstract
The purpose of this study was to compare the midterm results of a radiological and surgical approach to uterine fibroids. One hundred twenty-one women with reproductive plans who presented with an intramural fibroid(s) larger than 4 cm were randomly selected for either uterine artery embolization (UAE) or myomectomy. We compared the efficacy and safety of the two procedures and their impact on patient fertility. Fifty-eight embolizations and 63 myomectomies (42 laparoscopic, 21 open) were performed. One hundred eighteen patients have finished at least a 12-month follow-up; the mean follow-up in the entire study population was 24.9 months. Embolized patients underwent a significantly shorter procedure and required a shorter hospital stay and recovery period. They also presented with a lower CRP concentration on the second day after the procedure (p < 0.0001 for all parameters). There were no significant differences between the two groups in the rate of technical success, symptomatic effectiveness, postprocedural follicle stimulating hormone levels, number of reinterventions for fibroid recurrence or regrowth, or complication rates. Forty women after myomectomy and 26 after UAE have tried to conceive, and of these we registered 50 gestations in 45 women. There were more pregnancies (33) and labors (19) and fewer abortions (6) after surgery than after embolization (17 pregnancies, 5 labors, 9 abortions) (p < 0.05). Obstetrical and perinatal results were similar in both groups, possibly due to the low number of labors after UAE to date. We conclude that UAE is less invasive and as symptomatically effective and safe as myomectomy, but myomectomy appears to have superior reproductive outcomes in the first 2 years after treatment.

Abstract
RATIONALE AND OBJECTIVES Stereology is a simple, fast method for object segmentation that involves counting the number of intersections of a randomly positioned grid over an object. The objectives of this study were to determine observer reliability in making stereologic- and ellipsoid-based measurements of uterine and leiomyoma volumes and to test the agreement between these two methods of measurement. MATERIALS AND METHODS Two observers made uterine and dominant leiomyoma volume measurements on MR images in 30 patients using stereology and the popular ellipsoid-based technique. Stereologic volume measurements were made from high-resolution T2 images in two perpendicular planes (axial and sagittal). Ellipsoid volume was calculated by multiplying the maximal sagittal, anteroposterior, and transverse dimensions by pi/6. For these measurements, interobserver reliability was tested with paired t-tests and percent differences were determined. A mean stereologic volume and a mean ellipsoid volume were determined and tested for agreement with a paired t-test. Percent differences were also calculated. RESULTS Stereologic measurements demonstrated excellent interobserver reliability with 0.3% difference in mean uterine volumes (P = .69) and 0.3% difference (P = .81) in mean leiomyoma volumes. The ellipsoid method resulted in poorer interobserver reliability with 7% difference (P = .01) in mean uterine volumes and 4% difference (p = .24) in mean leiomyoma volumes. The ellipsoid method also significantly overestimated uterine volumes by 14% (P < .01) compared with stereology. CONCLUSION Stereology provided high interobserver reliability for leiomyoma and overall uterine volume measurements and was more reliable than the ellipsoid method, which uses linear measurements. Stereology appears well suited when precise volume measurements are desired for assessing response to uterine arterial embolization treatments.

Abstract
Transcatheter embolization of the uterine arteries for symptomatic fibroid disease has become an increasingly important alternative treatment. It is highly effective and well tolerated by most patients. Most notably, uterine artery embolization is associated with a short recovery period and is uterine sparing. To ensure the best chance for a safe and successful procedure, Interventional Radiologists should have familiarity with uterine artery anatomy, state of the art embolization techniques, and optimal patient selection and post procedure management.

Abstract
MR provides excellent depiction of the female pelvic anatomy and has become the imaging modality of choice for the accurate diagnosis of numerous benign gynecologic conditions. Detection and characterization of leiomyomata and adenomyosis is performed routinely at many centers, and MR plays an important role in stratifying patients into appropriate treatment options. MR imaging is also uniquely well suited to the evaluation of gynecologic conditions that occur during pregnancy and in the postpartum period. This article describes MR protocols and the typical findings of various benign conditions of the uterine corpus and cervix, including congenital anomalies, leiomyomas, adenomyosis, and complications related to pregnancy.
