Malformação arteriovenosa uterina: um relato de caso / Uterine arteriovenous malformation: a case report

O presente estudo tem como objetivo relatar o caso de uma paciente com malformação arteriovenosa uterina, efetivamente tratada com embolização seletiva e com fertilidade preservada. A malformação arteriovenosa uterina é uma alteração vascular rara até então pouco descrita na literatura. A paciente do sexo feminino apresentou quadro de sangramento uterino anormal, com início 30 dias após um abortamento, sem realização de curetagem, de uma gestação resultante de fertilização in vitro. Foram, então, realizados exames de imagem, que levaram ao diagnóstico de malformação arteriovenosa uterina. O tratamento de escolha foi a embolização arterial seletiva, com resolução do caso. Após sete meses, nova fertilização in vitro foi realizada, encontrando-se na 36a semana de gestação. São necessários mais estudos sobre essa malformação a fim de que sejam estabelecidos os métodos mais eficazes para o manejo de casos futuros, especialmente quando há desejo de gestar.

The present study aims to report the case of a patient with uterine arteriovenous malformation, effectively treated with selective embolization and with preserved fertility. Uterine arteriovenous malformation is a rare vascular disorder that has so far been rarely described in the literature. Female patient presented with abnormal uterine bleeding, starting 30 days after an abortion without subsequent curettage, of a pregnancy resulting from in vitro fertilization. Imaging tests were then performed that led to the diagnosis of uterine arteriovenous malformation. The treatment of choice was selective arterial embolization, with successful results. After seven months, a new in vitro fertilization was performed, being in the 36th week of pregnancy. Further studies on this pathology are needed in order to establish the most effective methods for the management of future cases, especially when there is a desire to become pregnant.

Efficacy of Embolization in Acquired Uterine Vascular Malformations: An Experience in Tertiary Care Centre in India / Eficácia da embolização em malformações vasculares uterinas adquiridas: uma experiência em centro de atendimento terciário na Índia

Abstract Objective: To determine the efficacy of Uterine Artery Embolization in patients with bleeding acquired uterine arteriovenous malformations (AVMs). Methods: A prospective review of all patients who underwent Uterine Artery Embolization at our institution between July 2015 and April 2022 was performed. 225 patients were diagnosed with a uterine vascular malformation on doppler and corresponding MRI imaging. All patients underwent transcatheter embolization of the uterine arteries. Embolic agents in the 375 procedures included Histoacryl glue only (n = 326), polyvinyl alcohol (PVA) particles and Histoacryl glue (n = 29), PVA particles (n = 5), Gelfoam (n = 5), coils (n = 4), PVA particles and coils (n = 3), Histoacryl glue and Gelfoam (n = 2), and Histoacryl glue and coils (n = 1). Results: A total of 375 embolization procedures were performed in 225 patients. 90 patients required repeat embolization for recurrence of bleeding. The technical success rate of embolization was 100%. The clinical success rate was 92%: bleeding was controlled in 222 of 225 patients and three patients underwent a hysterectomy. 60 of the 225 patients had uneventful intrauterine pregnancies carried to term. The 210 patients who underwent successful embolization had no recurrence of bleeding at a median follow-up of 53 months (range, 5-122 months) after treatment. 15 patients were eventually lost to follow-up. One minor complication (0.4%) of non-flow-limiting dissection of the internal iliac artery occurred. Conclusion: Uterine Artery Embolization is a safe, effective, minimally invasive method to treat uterine AVMs with long-term efficacy, which can provide the preservation of fertility.

Bloqueio do Nervo Hipogástrico Superior (BNHS) para o manejo da dor após Embolização de Artérias Uterinas (EAU): revisão de literatura / Superior Hypogastric Nerve Block (SHNB) for pain management in Uterine Artery Embolization (UAE): a literature review

Introdução: a embolização de artérias uterinas (EAU) é uma opção terapêutica no tratamento de miomas uterinos sintomáticos; todavia, a dor pós-procedimento representa um grande desafio para essa técnica. Nesse contexto, o Bloqueio do Nervo Hipogástrico Superior (BNHS), já utilizado no tratamento de dor pélvica crônica associada à malignidade, apresenta-se como opção de intervenção intraprocedimento para melhorar a recuperação das pacientes e fomentar o uso da EAU na prática clínica. Objetivo: realizar uma revisão integrativa da literatura disponível sobre o BNHS no manejo de dor pós EAU. Métodos: bases de dados PubMed, The Cochrane Library, Lilacs e Medline foram avaliadas a partir da combinação dos termos "uterine artery embolization", "pain" e "superior hypogastric block". Foram incluídos estudos clínicos, disponíveis em texto completo, com pacientes adultas, submetidas à EAU, cujo objetivo era avaliar o uso do BNHS e seu impacto na dor pós-procedimento. Foram excluídos artigos de revisão, carta ao editor, e publicação em anais de congresso. Resultados: 8 artigos, em maior parte retrospectivos, indicaram consistência do BNHS em termos de sucesso terapêutico a curto prazo e redução da dor. Apenas uma complicação foi relatada, e evoluiu de forma satisfatória. Conclusões: BNHS tem potencial de aprimorar o manejo da dor após EAU, podendo impactar positivamente no tempo e na qualidade da recuperação, com redução da dor e consumo de opiodes no período pós-operatório. Esses benefícios valorizam o procedimento de embolização como uma alternativa a ser considerada no tratamento de leiomiomas sintomáticos para mulheres candidatas à preservação uterina.

Introduction: Uterine Artery Embolization (UAE) is a therapeutic option in the treatment of symptomatic uterine fibroids; however, post-procedure pain imposes as a great challenge in this technique. In this context, the Superior Hypogastric Nerve Block (SHNB), already used in the treatment of chronic pelvic pain associated with malignancy, presents itself as an option for intraprocedural intervention, to improve patients' recovery and to promote UAE in the clinical setting. Objective: to perform an integrative literature review about the effectiveness of SHNB in pain management after UAE. Methods: databases PubMed, The Cochrane Library, Lilacs and Medline were assessed using the combination of the terms "uterine artery embolization", "pain" and "superior hypogastric block". Clinical studies were included once available in full text, with adult patients submitted to UAE, whose objective was to evaluate the use of SHNB and its impact in post-procedure pain. Review articles, letters to the editor, and publication in conference proceedings were excluded. Results: 8 articles were found, most of them retrospective, indicated SHNB's consistency in terms of short-term therapeutic success and pain reduction. The single reported complication evolved satisfactorily. Conclusions: SHNB has the potential to improve pain management after UAE, which can positively impact recovery time and quality, with reduced pain and consumption of opioids in the postoperative period. Benefits like these can enhance the embolization procedure as an alternative to be considered for the treatment of symptomatic fibroids for women candidates for uterine preservation.

Tratamiento del embarazo ectópico en cicatriz de cesárea: revisión de la literatura a propósito de 3 casos / Treatment of ectopic pregnancy in a cesarean scar: review of the literature regarding 3 cases

INTRODUCCIÓN Y OBJETIVOS: El embarazo en cicatriz de cesárea previa (ECC) es una entidad poco frecuente que puede tener graves consecuencias. Hasta la fecha no existen esquemas estandarizados de tratamiento y su manejo óptimo sigue siendo controvertido. Nuestro objetivo es realizar una revisión de la literatura publicada sobre el manejo del ECC y proponer un algoritmo. También exponemos tres casos de ECC resueltos con diferentes tratamientos en el Hospital Universitario Infanta Elena MÉTODOS: Búsqueda de la literatura en bases de datos utilizando las palabras clave: "embarazo en cicatriz cesárea"," gestación ectópica en cicatriz cesárea", "tratamiento", "manejo". RESULTADOS: Las opciones terapéuticas pueden ser médicas, quirúrgicas o una combinación de ambas. Los tratamientos quirúrgicos tienen altas tasas de éxito, sin embargo, son más invasivos y no están exentos de riesgo. La combinación de tratamientos parece aumentar la tasa de éxito, no obstante, podría implicar un mayor riesgo de efectos secundarios y costes. CONCLUSIONES: El manejo de los ECC debe de ser individualizado, basado en la evidencia científica, en los medios disponibles y la experiencia de los profesionales en los distintos procedimientos, guiándonos por el tipo de ECC y su grado de vascularización e invasión, grosor del miometrio, niveles de beta-hCG, presencia de actividad cardiaca, clínica y estabilidad hemodinámica de la paciente. Deben tenerse en cuenta las circunstancias y patología intercurrente de la mujer, así como su deseo genésico o de preservación del útero.

INTRODUCTION AND OBJECTIVES: Cesarean scar pregnancy (CSP) is a rare entity that can cause serious consequences. Up to now, there are no standardized treatment schemes, and its optimal management remains controversial. Our objetive is to review the literature regarding CSP management and propose an algorithm. We also present three cases of CSP resolved with different treatments at Hospital Universitario Infanta Elena. METHODS: Literature search in databases using the following keywords: pregnancy with cesarean section, ectopic pregnancy with cesarean section, treatment, management. RESULTS: The therapeutic options can be medical, surgical or a combination of both. Surgical treatments have high success rates; however, they are more invasive and are not without risk. The combination of treatments seems to increase the success rate; however, it could imply a higher risk of side effects and costs. CONCLUSIONS: The management of CSP must be individualized; based on scientific evidence, on the means available, and on the experience of the professionals in the different procedures; guided by the type of CSP and its degree of vascularization and invasion, by the thickness of the myometrium, beta-hCG levels, presence of cardiac activity, and by clinical and hemodynamic stability of the patient. The circumstances and intercurrent pathology of the patient must be considered, as well as her desire for future pregnancy or preservation of the uterus.

Cervical heterotopic pregnancy: A case report / 中南大学学报(医学版)

Heterotopic pregnancies are rare and difficult to be diagnosed early. A patient with combined intrauterine pregnancy and cervical pregnancy was admitted in Qingdao Municipal Hospital in 2019. The patient complained of abnormal vaginal bleeding after menopause and was misdiagnosed as simple intrauterine pregnancy. She underwent artificial abortion and suffered intraoperative hemorrhage. To stop bleeding, she received the treatment of uterine artery embolization immediately. Afterwards, cervical residual pregnancy tissues started necrosis, blood β-human chorionic gonadotropin level and the cervix appearance gradually returned to normal. This report suggests that cervical heterotopic pregnancy inclines to be mis diagnosed. Correct diagnosis should be made as soon as possible. Selective uterine artery embolization is an effective measure to prevent and treat massive bleeding.

Tratamento endovascular da miomatose uterina: uma revisão sistemática / Endovascular treatment of uterine myomatosis: a systematic review

Resumo A embolização da artéria uterina (EAU) é um tratamento pouco invasivo e alternativo à cirurgia aberta no tratamento de miomatose uterina. Este estudo visa analisar a eficácia e a segurança da EAU nesses casos. Para isso, foi realizada uma revisão sistemática a partir de estudos disponíveis nas bases de dados MEDLINE/PubMed, LILACS e PEDro, via Biblioteca Virtual em Saúde. Foram encontrados 817 trabalhos; destes, 7 foram selecionados pelos critérios de elegibilidade (estudos analíticos, de corte longitudinal, retrospectivos ou prospectivos), totalizando 367 pacientes no estudo. As variáveis estudadas, bem como as características dos estudos incluídos, foram coletadas e armazenadas em um banco de dados. As taxas de redução do volume uterino e do mioma dominante foram 44,1% e 56,3%, respectivamente. A média do infarto completo do mioma dominante foi de 88,6% (82-100%). Quanto às complicações, a média obtida foi de 15±8,6 casos, sendo a maioria destas classificadas como menores, e nenhum óbito foi registrado. A média de reabordagem em valores absolutos foi de 12,2±15,5 casos. Portanto, a embolização da artéria uterina é um procedimento eficaz e com baixa taxa de complicações para o tratamento da leiomiomatose uterina na literatura analisada.

Abstract Uterine Artery Embolization (UAE) is a noninvasive alternative to open surgery for treatment of uterine myomatosis. This study aims to analyze the efficacy and safety of UAE in these cases. A systematic review was carried out of studies available on the Medline (via PubMed) and the LILACS and PEDro (via the Biblioteca Virtual em Saúde) databases. The searches found 817 studies, 7 of which were selected according to the eligibility criteria (analytical, longitudinal, retrospective, or prospective studies), with a total of 367 patients studied. The variables analyzed and the characteristics of the studies included were collated and input to a database. Rates of volume reduction of the uterus and the dominant myoma were 44.1% and 56.3%, respectively. Mean rate of complete infarction of the dominant myoma was 88.6% (82-100%). The mean number of complications observed was 15±8.6 cases, most of which were classified as minor, and no deaths were recorded. The mean number of re-interventions in absolute values was 12.2±15.5 cases. Therefore, in the literature analyzed, uterine artery embolization is an effective procedure with a low rate of complications for treatment of uterine leiomyomatosis.

Hemoperitoneo en el post parto secundario a la rotura aneurismática de la arteria ovárica: Caso Clínico / Post partum hemoperitoneum secondary to ovarian aneurysm rupture: Case Report

Resumen El hallazgo de hemoperitoneo en el post parto secundario a la rotura aneurismática de la arteria ovárica es una situación clínica extremadamente rara que presenta un cuadro clínico inespecífico y puede poner en riesgo la vida del paciente. El ultrasonido es una modalidad segura y rápida para la detección de líquido libre intraperitoneal. (1) . La tomografía computada es la herramienta de elección para un diagnóstico rápido y seguro (2) ; y la angiografía con embolización durante el mismo procedimiento es una alternativa útil y altamente efectiva para la resolución del cuadro. (3). Presentamos el caso de una multípara puérpera de 34 años que consulta en el servicio de urgencia por intenso dolor abdominal. La paciente se encontraba hemodinámicamente estable y afebril. La tomografía computada demostró un hematoma retroperitoneal y hemoperitoneo asociado a un aneurisma de la arteria ovárica derecha. Fue evaluada por el servicio de radiología intervencional y se trasladó de emergencia al pabellón angiográfico donde se realizó la embolización de la lesión mediante la cateterización vascular supra selectiva. La paciente evolucionó de manera favorable y fue dada de alta una semana después. Es necesario tener un alto índice de sospecha en pacientes de riesgo para lograr un diagnóstico y tratamiento oportuno.

SUMMARY Spontaneous ovarian artery aneurysm rupture is a rare postpartum life-threatening event with non-specific clinical manifestations. The present article reports the case of a 34 year old multiparous post partum women who came to the emergency department with acute onset of intense abdominal right flank pain. Patient was afebrile and hemodynamically stable. A computed tomography revealed a retroperitoneal haematoma and hemoperitoneum related to an aneurysm of the right ovarian artery. The patient was taken to the interventional radiology suite and selective embolization was performed. Following the procedure, the patient symptoms subsided and 7 days later she was discharged. A high index of suspicion in patients with risk factors can lead to a prompt diagnosis and treatment. Computed tomography is the image modality for a fast and safe evaluation, although diagnostic angiography and subsequent transcatheter embolization are thought to be effective for treatment.

Embarazo ectópico cervical / Cervical Ectopic Pregnancy

El embarazo ectópico cervical representa alrededor de 0,1 por ciento de todos los embarazos ectópicos. La incidencia se estima en 1: 2500 a 1: 98,000 embarazos. Es un fenómeno extraño; sin embargo, la morbilidad y la mortalidad por esta causa son elevadas, pero pueden disminuirse con el diagnóstico temprano. Es extremadamente peligroso porque el trofoblasto puede alcanzar los vasos uterinos a través de la delgada pared cervical y provocar una hemorragia grave e incoercible que aun en la actualidad suele terminar en cirugías mutilantes que limitarán la reproducción futura. En la actualidad, no existen criterios claros en la bibliografía que ayuden a la toma de decisiones. Se reporta un caso de embarazo cervical tratado exitosamente mediante histerectomía total abdominal y posterior seguimiento en la Unidad de Cuidados Intensivos. Se exponen algunos criterios que en el futuro podrían ayudar a diagnosticar esta entidad devastadora de forma oportuna para disminuir la morbimortalidad por esta causa y mejorar las posteriores posibilidades reproductivas de la mujer(AU)

Cervical ectopic pregnancy accounts for about 0.1 percent of all ectopic pregnancies. The incidence is estimated at 1: 2500 to 1: 98,000 pregnancies. It is a strange phenomenon; however, morbidity and mortality from this cause are high, but early diagnosis can help reducing. It is extremely dangerous because the trophoblast can reach the uterine vessels through the thin cervical wall and cause a severe and incoercible hemorrhage that, even today, usually ends in mutilating surgeries that will limit future reproduction. At present, no clear criteria in the literature help decision-making. We report a case of cervical pregnancy successfully treated by total abdominal hysterectomy and subsequent follow-up in the Intensive Care Unit. We present some criteria that could help timely diagnosing this devastating entity to reduce morbidity and mortality and improve the later reproductive possibilities of women(AU)

Embolização de artéria uterina para hemorragia pós-parto: uma revisão de literatura / Uterine artery embolization for postpartum hemorrhage: a review of the literature

A hemorragia pós-parto é uma emergência obstétrica que acomete grande parcela de puérperas e leva à extensa quantidade de óbitos por ano. Entre as suas principais causas estão a atonia uterina e o acretismo placentário. Atualmente, as técnicas mais utilizadas para a resolução do sangramento se apresentam por muitas vezes ineficazes e/ou levam à infertilidade feminina. O presente estudo trata-se de uma revisão da literatura em modelo PRISMA, no qual foram selecionados 35 artigos dos últimos 12 anos, nas bases de dados do UpToDate, SciELO, PubMed, Plos ONE, Lilacs e Datasus, no qual serão apresentadas evidências de que, nas mãos de um profissional treinado, a embolização de artéria uterina se mostra como uma excelente alternativa no tratamento da hemorragia obstétrica, apresentando-se como terapêutica minimamente invasiva, com altas taxas de sucesso, baixo número de complicações e que preserva a função reprodutiva da mulher.(AU)

The post-partum hemorrhage is an obstetric emergency that affects a big percentage of women who have recently given birth and leads to a big amount of deaths per year. Its main causes are uterine atony and placentary accretism. Currently the main techniques for its resolution are the utilization of uterotonics and aggressive surgical approaches to the pelvic structure, which are commonly inefficient or bring long term injuries to the fertility. This study is a literature review structure on PRISMA model, where was selected 35 articles of the last 12 years, in these databases: UpToDate, SciELO, PubMed, Plos ONE, Lilacs and Datasus, in which will be presented evidences of, in expert professional hands, uterine artery embolization being an excellent alternative in the treatment of obstetric hemorrhage, presenting itself a minimally invasive technique, with high rates of success, low numbers of complications and the capacity of preserving the patient reproductive system.(AU)

Uterine Artery Embolization for Leiomyomas and Adenomyosis: A Pictorial Essay Based on Our Experience from 1300 Cases

Since its introduction in 1995, uterine artery embolization (UAE) has become an established option for the treatment of leiomyomas. Identification of a leiomyoma using arteriography improves the ability to perform effective UAE. UAE is not contraindicated in a pedunculated subserosal leiomyoma. UAE in a cervical leiomyoma remains a challenging procedure. A leiomyoma with high signal intensity on T2-weighted imaging responds well to UAE, but a malignancy with similar radiological features should not be misdiagnosed as a leiomyoma. Administration of gonadotropin-releasing hormone agonists before UAE is useful in selected patients and is not a contraindication for the procedure. The risk of subsequent re-intervention 5 years after UAE is approximately 10%, which represents an acceptable profile. UAE for adenomyosis is challenging; initial embolization using small particles can achieve better success than that by using larger particles. An intravenous injection of dexamethasone prior to UAE, followed by a patient-controlled analgesia pump and intra-arterial administration of lidocaine after the procedure, are useful techniques to control pain. Dexmedetomidine is an excellent supplemental sedative, showing a fentanyl-sparing effect without causing respiratory depression. UAE for symptomatic leiomyoma is safe and can be an alternative to surgery in most patients with a low risk of re-intervention.

Uterine arteriovenous malformation with repeated vaginal bleeding after dilatation and curettage

Uterine arteriovenous vascular malformation (UAVM) is a disease that causes excessive bleeding. The symptoms do not subside without proper treatment and this can lead to life-threatening situations. The correct diagnosis of UAVM can be complicated if the patient's uterus did not completely discharge everything during abortion (in broader terms, retaining remnants of the products of conception). In this case, Doppler ultrasonography and computed tomography angiography with 3-dimensional rendering were used to analyze the cause of bleeding and provide proper treatment of this patient. Then, uterine artery embolization, dilatation, and curettage were performed safely and successfully. The patient no longer had symptoms of vaginal spotting during the planned follow up care. UAVM is uncommon; however, if reproductive-age women show repeated abnormal vaginal bleeding after dilatation and curettage, a diagnosis of UAVM must be considered based on the medical history and examination.

Outcome of re-pregnancy in women with uterine artery embolization for postpartum hemorrhage / 浙江大学学报·医学版

OBJECTIVE@#To evaluate the outcome of re-pregnancy in women with uterine artery embolization(UAE)for postpartum hemorrhage(PPH).@*METHODS@#Clinical data of 117 pregnant women with previous PPH admitted in Ningbo Women and Children's Hospital from January 2010 to January 2016 were retrospectively analyzed. Among them 40 cases were treated with UAE (UAE group) and 77 cases were not treated with UAE (control group). The outcomes of re-pregnancy were followed up and compared between two groups.@*RESULTS@#There were significant differences in the incidence of induced abortion in early pregnancy and cesarean scars pregnancy (CSP) between the two groups (<0.05 or <0.01). In the UAE group, the incidence of PPH, placental accretion and hysterectomy rate was significantly higher than that of control group (<0.05 or <0.01). Multivariate analysis showed that UAE was independent risk factor for CSP, placenta accretion, PPH and hystere-ctomy (<0.05 or <0.01).@*CONCLUSIONS@#The overall fertility and re-pregnant outcomes in women with previous UAE for PPH are favorable. However, the risk of CSP, placenta accretion and associated recurrence of PPH and hysterectomy is higher in women receiving UAE during subsequent pregnancy.

Can the combination of internal iliac temporary occlusion and uterine artery embolization reduce bleeding and the need for intraoperative blood transfusion in cases of invasive placentation?

OBJECTIVES: Women with invasive placentation (IP) are at high risk of life-threatening hemorrhage. In the last two decades, less invasive surgical approaches combined with endovascular procedures have proven to be safe. Most case series describe the use of temporary balloon occlusion and embolization, either combined or not. Concerning hemorrhage rates, each separate interventional approach performs better than surgery alone does, yet it is not clear whether the combination of multiple interventional techniques can be beneficial and promote a lower incidence of intrapartum bleeding. We aim to evaluate whether combining temporary balloon occlusion of the internal iliac artery and uterine artery embolization promotes better hemorrhage control than do other individual interventional approaches reported in the scientific literature in the context of cesarean birth followed by hysterectomy in patients with IP. METHODS: This is a retrospective analysis of patients with confirmed IP who underwent temporary balloon occlusion and embolization of the internal iliac arteries followed by puerperal hysterectomy. We compared patient results to data extracted from a recent systematic review and meta-analysis of the current literature that focused on interventional procedures in patients with IP. RESULTS: A total of 35 patients underwent the procedure during the study period in our institution. The mean volume of packed red blood cells and the estimated blood loss were 487.9 mL and 1193 mL, respectively. Four patients experienced complications that were attributed to the endovascular procedure. CONCLUSION: The combination of temporary balloon occlusion and uterine artery embolization does not seem to promote better hemorrhage control than each procedure performed individually does.

Patient Blood Management: Obstetrician, Gynecologist's Perspectives / 한양의대학술지

Obstetricians and gynecologists frequently deal with hemorrhage so they should be familiar with management of patient blood management (PBM). We will review to summarize the alternative measures and interventions used in bloodless surgery in the field of obstetrics and gynecology. In the obstetric field, PBM has been developed as an evolving evidence-based approach with a number of key goals: (i) to identify, evaluate, and manage anemia; (ii) reduce iatrogenic blood loss; (iii) optimize hemostasis; and (iv) establish decision thresholds for transfusion. Transfusion, mechanical method including balloon tamponade and uterine artery embolization, and intraoperative cell salvage were introduced for PBM. In the gynecologic field, PBM is not significantly different from that in the obstetric field. Preoperative managements include iron supplement, erythropoietin administration, autologous blood donation, and uterine artery embolization. Meticulous hemostasis, short operative time, hypotensive anesthetic techniques, hemodilution during operation, blood salvage and pharmacological agents were introduced to intraoperative management. Postoperative measures include meticulous postoperative monitoring of the patient, early detection of blood loss, reduction of blood sampling, appropriate use of hemopoiesis, normalization of cardio-pulmonary function and minimization of oxygen consumption. In conclusion, each obstetrician and gynecologist should be aware about the appropriate method for blood conservation and use in practice. A comprehensive approach to coordinating all members of the bloodless agent and surgical team is essential.

Measurement of uterine leiomyomata volume pre and post uterine artery embolization aided by MRI

Background: uterine fibroid embolization [UFE] is now evolving to be the first-line treatment for symptomatic uterine leiomyomata alongside the conventional surgical treatment of hysterectomy and myomectomy. Cochrane review comprises six RCTs comparing UAE versus hysterectomy or myomectomy for management of symptomatic leiomyomata where UFE had similar short and midterm outcomes, inclusive of symptomatic relief, quality of life and patient satisfaction, while benefiting from uterine preservation, shorter hospital stay and a faster recovery before resuming ordinary life activities. These benefits are in line with the minimally invasive nature of the embolization procedures

Aim of the Work: t this study aimed to review and illustrate the role of MR imaging in the pre- and post-procedural assessment for uterine fibroid patients undergoing uterine artery embolization

Patients and Methods: the current study was carried out in Radiodiagnosis Department, Faculty of Medicine, Ain shams University and specialized private radiology centers during the period between April 2017 and December 2017. It included 30 patients that were referred from gynecology clinic with their ultrasonographic reports to Radiodiagnosis Department, body imaging unit with a view to carry-out pelvic MRI with contrast

Results: imaging follow-up via pelvic MRI with contrast was obtained in 30 patients at 3, 6 months after treatment. The mean uterine volume was reduced by 25% [standard deviation was SD 0.03763] 3 months after treatment and was further reduced by a mean of 30% [SD 0.02638] by six months after treatment. Post-procedural subtraction MRI revealed mean myoma enhancement to be 5.6 + 0.5 SI in contrast to 133.4 + 18.3 SI prior to UFE. The mean dominant fibroid volume reduced by 34 % [SD 0.09247] after 3 months, 44 % [SD 0.05994] after 6 months. A cumulative reduction in both uterine and dominant leiomyoma mean volume from baseline to 6 months post - UAE was evident with significant interval changes between 3, 6 months follow up [p 0.000]

Conclusion: the MRI findings following UAE vary with the interval from embolization and success of the procedure. MRI with its multiplanar capabilities was typically employed to evaluate the uterus following UAE for fibroid infarction, size reduction, location change, persistent enhancement, fibroid recurrence, changes in adenomyosis, and unexpected complications that may require surgical intervention or identify women who would benefit from repeated UAE

Recommendations: further studies on a larger scale of patients are needed to confirm the results obtained by this work

Risk factors for massive postpartum bleeding in pregnancies in which incomplete placenta previa are located on the posterior uterine wall

OBJECTIVE: To identify factors associated with massive postpartum bleeding in pregnancies complicated by incomplete placenta previa located on the posterior uterine wall. METHODS: A retrospective case-control study was performed. We identified 210 healthy singleton pregnancies with incomplete placenta previa located on the posterior uterine wall, who underwent elective or emergency cesarean section after 24 weeks of gestation between January 2006 and April 2016. The cases with intraoperative blood loss (≥2,000 mL) or transfusion of packed red blood cells (≥4) or uterine artery embolization or hysterectomy were defined as massive bleeding. RESULTS: Twenty-three women experienced postpartum profuse bleeding (11.0%). After multivariable analysis, 4 variables were associated with massive postpartum hemorrhage (PPH): experience of 2 or more prior uterine curettage (adjusted odds ratio [aOR], 4.47; 95% confidence interval [CI], 1.29 to 15.48; P=0.018), short cervical length before delivery (<2.0 cm) (aOR, 7.13; 95% CI, 1.01 to 50.25; P=0.049), fetal non-cephalic presentation (aOR, 12.48; 95% CI, 1.29 to 121.24; P=0.030), and uteroplacental hypervascularity (aOR, 6.23; 95% CI, 2.30 to 8.83; P=0.001). CONCLUSION: This is the first study of cases with incomplete placenta previa located on the posterior uterine wall, which were complicated by massive PPH. Our findings might be helpful to guide obstetric management and provide useful information for prediction of massive PPH in pregnancies with incomplete placenta previa located on the posterior uterine wall.

The efficacy of pre-delivery prophylactic trans-catheter arterial balloon occlusion of bilateral internal iliac artery in patients with suspected placental adhesion

OBJECTIVE: Prophylactic trans-catheter arterial balloon occlusion (PTABO) before cesarean section of placenta previa totalis has been introduced to prevent massive hemorrhage. The purpose of this study is to evaluate the clinical usefulness of PTABO in cases of suspected placental adhesion and to examine antepartal risk factors and perinatal outcomes in women with placental adhesion. METHODS: Between January 2012 and December 2015, 77 patients who had undergone ultrasonography for evaluation of placenta previa were enrolled in this study. Seventeen of these patients with suspected placental adhesion by ultrasonography and Pelvic MRI underwent PTABO before cesarean section and another 59 patients underwent cesarean section without PTABO. Antepartal risk factors and peripartum maternal and neonatal outcomes were compared between patients with PTABO and those without PTABO. RESULTS: More advanced maternal age, longer in gestational weeks at delivery, and more common previous cesarean section history were observed in the PTABO group. Placenta adhesion, abnormal Doppler findings, and frequency of transfusion were more common in the PTABO group. However there was no significant difference in estimated blood loss, hospital days, and neonatal outcome. It had occurred 3 cases of hysterectomy and 1 case of uterine artery embolization after cesarean section in the PTABO group. CONCLUSION: Close surveillance of antepartum risk factors for placental adhesion using ultrasonography and pelvic magnetic resonance imaging is important to prevention of massive hemorrhage during cesarean section. PTABO before cesarean section might result in reduced blood loss and requirement for transfusion during the operation.

Delayed postpartum hemoperitoneum due to uterine artery pseudoaneurysm rupture

A 30-year-old woman experienced severe abdominal pain 8 days after vaginal delivery. The patient was diagnosed with hemoperitoneum due to rupture of the left uterine artery pseudoaneurysm, which was confirmed via ultrasound with color Doppler and computed tomography scans. This patient was treated with bilateral uterine artery embolization to maintain fertility. A uterine artery pseudoaneurysm that causes delayed postpartum hemorrhage can occur after cesarean section or vaginal delivery. A uterine artery pseudoaneurysm can be fatal, so its detection and diagnosis are critical. Herein, we report a case of delayed postpartum hemoperitoneum due to uterine artery pseudoaneurysm rupture.

Efficacy of Prophylactic Uterine Artery Embolization before Obstetrical Procedures with High Risk for Massive Bleeding

OBJECTIVE: To evaluate the safety and efficacy of prophylactic uterine artery embolization (UAE) before obstetrical procedures with high risk for massive bleeding. MATERIALS AND METHODS: A retrospective review of 29 female patients who underwent prophylactic UAE from June 2009 to February 2014 was performed. Indications for prophylactic UAE were as follows: dilatation and curettage (D&C) associated with ectopic pregnancy (cesarean scar pregnancy, n = 9; cervical pregnancy, n = 6), termination of pregnancy with abnormal placentation (placenta previa, n = 8), D&C for retained placenta with vascularity (n = 5), and D&C for suspected gestational trophoblastic disease (n = 1). Their medical records were reviewed to evaluate the safety and efficacy of UAE. RESULTS: All women received successful bilateral prophylactic UAE followed by D&C with preservation of the uterus. In all patients, UAE followed by obstetrical procedure prevented significant vaginal bleeding on gynecologic examination. There was no major complication related to UAE. Vaginal spotting continued for 3 months in three cases. Although oligomenorrhea continued for six months in one patient, normal menstruation resumed in all patients afterwards. During follow-up, four had subsequent successful natural pregnancies. Spontaneous abortion occurred in one of them during the first trimester. CONCLUSION: Prophylactic UAE before an obstetrical procedure in patients with high risk of bleeding or symptomatic bleeding may be a safe and effective way to manage or prevent serious bleeding, especially for women who wish to preserve their fertility.
