RESUMEN

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)

RESUMEN

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)

RESUMEN

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.

RESUMEN

OBJECTIVES: To evaluate the clinical response and success rate after periuterine varices embolization in patients with chronic pelvic pain secondary to pelvic congestion syndrome and to report the safety of endovascular treatment and its rate of complications. METHODS: Retrospective cohort of patients undergoing endovascular treatment of pelvic congestion syndrome in our department from January 2012 to November 2015. Data were analyzed based on patient background, imaging findings, embolized veins, rate of complications, and clinical response as indicated by the visual analog pain scale. RESULTS: We performed periuterine varices embolization in 22 patients during the study, four of which required a second embolization. Seventeen patients reported a reduction in pelvic pain after the first embolization and three patients reported a reduction in pelvic pain after the second embolization. Minor complications were observed in our patients, such as postural hypotension, postoperative pain, and venous perforation during the procedure, without clinical repercussion. CONCLUSION: Periuterine varices embolization in patients with chronic pelvic pain secondary to pelvic congestion syndrome appears to be an effective and safe technique.

RESUMEN

The advent of interventional radiology enabled remarkable advances in diagnosis and treatment of several situations in obstetrics and gynecology. In the field of obstetrics, these advances include temporary occlusion of the iliac arteries to the management of placenta accreta and/or prior, arteriovenous fistulas after embolization of uterine curettage and management of ectopic uterine and extra-uterine pregnancies. The non-tubal ectopic pregnancy, either cervical, abdominal, ovarian or in a cesarean scar, often represents major therapeutic challenge, especially when exists a desire to maintain fertility. Despite the systemic methotrexate therapy and surgical resection of the ectopic gestational sac be the most used therapeutic options, the interventionist approach of non-tubal ectopic pregnancies, direct injection of methotrexate in the gestational sac and intra-arterial chemoembolization of uterine arteries constitute in the currently literature viable, safe, effective modalities with low morbidity, shorter hospital stay, and rapid clinical recovery. Because of little variety of materials used, and the increase in training of specialists in the area, the radiological intervention as a treatment option in ectopic pregnancies is financially viable and present considerable accessibility in the world and at most of Brazilian medical centers.


O advento da radiologia intervencionista tornou possível avanços notáveis no diagnóstico e no tratamento de diversas situações, na área de ginecologia e obstetrícia. No campo da obstetrícia, esses avanços incluem oclusão temporária das artérias hipogástricas para o manejo de placenta acreta e/ou prévia, embolização de fístulas arteriovenosas após curetagem uterina e manejo de prenhezes ectópicas uterinas e extrauterinas. A gravidez ectópica não tubária, seja cervical, abdominal, ovariana ou na cicatriz de cesárea, muitas vezes representa grande desafio terapêutico, principalmente quando há desejo de manutenção da fertilidade. As opções terapêuticas mais utilizadas para o tratamento de prenhez ectópica não tubária, são: terapia sistêmica com metotrexato e ressecção cirúrgica do saco gestacional ectópico; porém a abordagem intervencionista com injeção direta de metotrexato no saco gestacional ou quimiembolização intra-arterial das artérias uterinas, apresentam-se na literatura recente, como modalidades terapêuticas viáveis, seguras, eficazes, com baixa morbidade, menor tempo de internação e rápida recuperação clínica. Devido ao diminuto arsenal de materiais utilizados e à crescente formação de especialistas na área, a intervenção radiológica, como opção de tratamento nas prenhezes ectópicas, é financeiramente viável e apresenta acessibilidade considerável no mundo e na maioria do centros médicos brasileiros.

RESUMEN

Las malformaciones vasculares uterinas son muy infrecuentes y se presentan asociadas a metrorragia con riesgo vital. Su incidencia no es conocida porque las series son de pocos casos. Presentamos tres pacientes con hemorragia obstétrica cuyo estudio diagnóstico con ultrasonido y angiografía, demostró malformación arteriovenosa uterina. En un caso, dada la extensión de la lesión, el tratamiento fue con embolización bilateral de arterias uterinas seguida de histerectomía. Otras dos pacientes, por preservación de fertilidad, fueron sometidas solo a embolización. La evolución clínica y las imágenes confirmaron que los procedimientos fueron exitosos. Se discute la importancia de la interpretación correcta de las imágenes para el diagnóstico, la adaptación de los métodos terapéuticos al caso individual y el manejo multidisciplinario.


The uterine vascular malformations are very infrequent and associated to maternal hemorrhage with vital risk. The incidence is unknown because the published series are little with few cases. We described three cases with obstetrical hemorrhage and the image study with ultrasound and angiography showed an arteriovenous malformation. One patient, for the extensive lesion, was treated with bilateral embolization of uterine arteries and then, histerectomy. The others patients, for preservation her fertility, were treated with embolization only. The clinical evolution and the vascular images study confirm the success of the procedures. We discuss the importance of images analysis for the diagnosis, the individual application of therapeutic methods and a multidisciplinary approach for this scope.

RESUMEN

OBJECTIVE: Minimally invasive methods are used as alternatives to treat leiomyomas and include uterine artery embolization, which has emerged as a safe, effective method. This study aims to evaluate the magnetic resonance imaging predictors for a reduction in leiomyoma volume in patients undergoing uterine artery embolization. METHODS: This prospective longitudinal study was performed at a university hospital. We followed 50 symptomatic premenopausal women with uterine leiomyomas who underwent uterine artery embolization. We examined 179 leiomyomas among these patients. Magnetic resonance imaging was performed one month before and six months after uterine artery embolization. Two radiologists who specialized in abdominal imaging independently interpreted the images. Main Outcome Measures: The magnetic resonance imaging parameters were the uterus and leiomyomas volumes, their localizations, contrast perfusion pattern and node-to-muscle ratio. RESULTS: Six months after treatment, the average uterine volume reduction was 38.91%, and the leiomyomas were reduced by 55.23%. When the leiomyomas were submucosal and/or had a higher node-to-muscle ratio in the T2 images, the volume reduction was even greater (greater than 50%). Other parameters showed no association. CONCLUSIONS: We conclude that symptomatic uterine leiomyomas in patients undergoing uterine artery embolization exhibit volume reductions greater than 50% by magnetic resonance imaging when the leiomyomas are submucosal and/or had a high node-to-muscle ratio in the T2 images. .

RESUMEN

A procura por procedimentos menos invasivos, e o desejo das mulheres de manter o útero, fazem da oclusão laparoscópica das artérias uterinas no tratamento de leiomiomas uterinos uma alternativa. Este trabalho teve como objetivo revisar os estudos sobre essa cirurgia. Os resultados após as intervenções cirúrgicas relatam redução volumétrica do útero e leiomiomas, com melhora dos sintomas e menos dor no pós-operatório em relação à embolização das artérias uterinas, técnica que utiliza o mesmo conceito da desvascularização do tumor. Quanto ao futuro reprodutivo, os dados não são bem definidos e apresentam-se conflitantes. As recorrências dos sintomas e possível necessidade de novas cirurgias complementares podem causar insatisfação entre as pacientes. Novos estudos são necessários para melhor definir o papel dessa opção terapêutica no tratamento de leiomiomas uterinos


The search for less invasive surgical procedures, and the desire of women to keep the uterus, make laparoscopic occlusion of the uterine arteries an alternative in the treatment of uterine leiomyomas. Current paper reviewed studies on this type of surgery, volume reduction of uterus and leiomyomas, with improvement in symptoms and less pain in the postoperative period in relation to uterine artery embolization, a technique The results showed that after surgical intervention a decrease occurred in uterus volume and leiomyomas, with symptom improvement and less pain in the postoperative period when compared to the embolization of the uterine arteries, a technique that uses the same concept of devascularization of the tumor. Data are not clear with regard to future reproduction and they prove to be conflicting. The recurrence of symptoms and the need for other complementary surgeries may be a cause of dissatisfaction among the patients. Further studies are required to define convincingly the role of the therapeutic option in the treatment

RESUMEN

Objetivo: Evaluar las complicaciones asociadas a la miomectomía laparotómica y a la embolización de las arterias uterinas en mujeres con miomas sintomáticos. Métodos: Estudio descriptivo restrospectivo efectuado en el Complejo Hospitalario Universitario de Vigo desde el año 2008 al 2010. La población en estudio la conformaron aquellas mujeres sometidas a una miomectomía laparotómica o a una embolización de las arterias uterinas. Se recopilaron las complicaciones registradas en las historias clínicas de las pacientes tras las técnicas. Resultados: La tasa de complicaciones en el grupo de las pacientes sometidas a miomectomía fue de 15,2 por ciento; las más frecuentes fueron fiebre, anemia, necesidad de trasfusión y hematoma subcutáneo. La tasa de complicaciones en el grupo de embolización fue de 4,5 por ciento recogiéndose casos de síndrome postembolización, mioma parido y un caso de histerectomía. Conclusión: La adecuada indicación de cada técnica es fundamental para tener una baja tasa de complicaciones. Se debe tener en cuenta la sintomatología, tipo y número de miomas, edad y deseo genésico de cada paciente.


Objective: This study was undertaken to evaluate the complications after laparotomy myomectomy and uterine artery embolization in women with symptomatic uterine leiomyoma. Methods: This was a descriptive and retrospective study of patients who were treated with embolization and myomectomy for leiomyomas from 2008-2010. Complications were measured. Results: The rate of complications collected in the myo-mectomy group was 15.2 percent; there were cases of fever, anemia, need for transfusion and subcutaneous hematoma. The rate of complications collected in the embolization group was 4.5 percent; there were cases of embolization syndrome, transcervical fibroid expulsion and a case of hysterectomy. Conclusion: The suitable indication of every tecnic is fundamental to have a low rate of complications. It is necessary to bear in mind the symptomatology, type and number of myomas and age and reproductive desire of each patient.

RESUMEN

OBJECTIVE: To evaluate the effectiveness of uterine artery embolization (UAE) for treating symptomatic fibroids with high signal intensity (SI) on magnetic resonance (MR) T2-weighted imaging (T2WI). MATERIALS AND METHODS: A total of 537 cases, consisting of 14 patients with high SI fibroids on T2WI (T2 high group), were retrospectively included and compared with 28 randomly selected patients with low SI fibroids on T2WI (control group). High SI of a predominant fibroid on T2WI was defined as having the same or higher SI than the myometrium. Patient ages ranged from 28 to 52 years (mean, 38.1 years). All patients underwent MRI before and after UAE. Predominant fibroid and uterine volumes were calculated with MR images. Symptom status in terms of menorrhagia and dysmenorrhea was scored on a scale of 0-10, with 0 being no symptoms and 10 being the baseline, or initial symptoms. RESULTS: Of the patients in the T2 high group, 13 out of 14 (92.9%) patients demonstrated complete necrosis of the predominant fibroids. The mean volume reduction rates of the predominant fibroids in the T2 high group was 61.7% at three months after UAE, which was significantly higher than the volume reduction rates of 42.1% noted in the control group (p < 0.05). Changes in symptom scores for menorrhagia and dysmenorrhea after UAE (baseline score minus follow-up score) were 4.9 and 7.5 in T2 high group and they were 5.0 and 7.7 in control group, suggesting a significant resolution of symptoms (p < 0.01) in both groups but no significant difference between the two groups. CONCLUSION: UAE is effective for uttering fibroids showing high SI on T2WI. The mean volume reduction rate of the predominant fibroids three months after UAE was greater in the T2 high group than in the control group.
