ABSTRACT

Introducción. El objetivo de este artículo fue dar a conocer el protocolo institucional del manejo de la placenta percreta como un procedimiento varias horas después de la cesárea, con embolización de arterias placentarias de forma selectivas, previo a la práctica de la histerectomía, y presentar los resultados. Métodos. Estudio de serie de casos, donde se evaluaron las pacientes con placenta percreta, manejadas durante un año en un hospital de cuarto nivel de complejidad en la ciudad de Bogotá, D.C., Colombia. Se efectuó cesárea fúndica y se dejó la placenta in situ, 48 a 72 horas después se realizó embolización ultra selectiva y luego de 2 a 3 días se procedió a practicar la histerectomía vía abdominal. Resultados. Se evaluaron 5 pacientes, con paridad de 3,8 embarazos promedio, con diagnóstico de placenta percreta. El tiempo promedio de espera entre la embolización y la histerectomía fue de 1,6 días. No se presentaron complicaciones asociadas a la embolización, ni morbimortalidad materno fetal. Los volúmenes de sangrado en promedio durante la histerectomía de cada paciente fueron de 1160 ml. Conclusión. Existen datos limitados sobre el tratamiento óptimo del acretismo placentario. La sospecha diagnóstica permite planificar de forma favorable el manejo intraparto y, es por ello, que el surgimiento de nuevas técnicas, como la embolización de arterias placentarias, constituyen alternativas para un manejo más seguro de las pacientes.


Introduction. The objective of this article was to present the institutional protocol for the management of percrete placenta as a procedure several hours after cesarean section, with selective embolization of placental arteries, prior to the practice of hysterectomy, and to present the results. Methods. Case series study, where patients with percrete placenta were evaluated, managed for 1 year in a hospital of fourth level of complexity in the city of Bogotá, Colombia. A fundic cesarean section was performed and the placenta was left in situ, 48 to 72 hours later an ultra-selective embolization was performed, followed by an abdominal hysterectomy after 2 to 3 days.Results. Five patients with a diagnosis of placenta percreta were evaluated; mean wait time between embolization and hysterectomy was 1.6 days. There were no complications associated with embolization, or maternal-fetal morbidity and mortality. Average bleeding volumes during hysterectomy for each patient were 1160 ml. Conclusion. There are limited data on the optimal treatment of percrete placenta. Diagnostic suspicion allows for a favorable planning of intrapartum management and, for this reason, the emergence of new techniques, such as placental artery embolization, constitute alternatives for a safer management of patients.

ABSTRACT

Introducción. Las malformaciones arteriovenosas son lesiones relativamente raras e infrecuentes. Se caracterizan por presentar un aumento anormal en el número de vasos sanguíneos como consecuencia de un defecto en el desarrollo vascular. Constituyen un desafío diagnóstico y terapéutico para el médico tratante. Su incidencia es de alrededor el 1.5% de la población general. Dentro de las opciones terapéuticas se incluye la embolización selectiva, la resección quirúrgica o ambas. El objetivo del presente artículo es reportar un caso de una patología poco frecuente y hacer una revisión literaria del tema para arrojar luz sobre su diagnóstico. Reporte de caso. Se presenta el caso de un paciente adulto joven que consulta por presentar una masa en glúteo derecho de 6 años de evolución. Esta es diagnosticada erróneamente como lipoma, por lo que se lleva al paciente a cirugía sin la realización de imágenes diagnósticas previas. En la cirugía, el paciente presenta choque hipovolémico. Posteriormente, se documenta la masa como malformación arteriovenosa profunda. Discusión. Es poco usual la ubicación de dichas malformaciones en los miembros inferiores, como en el paciente del actual caso. El diagnóstico de estas lesiones puede ser clínico, pero requiere del conocimiento o sospecha de esta entidad, ya que pueden ser lesiones clínicamente no visibles, lo que lleva a que pasen inadvertidas o se diagnostiquen de forma errónea. Conclusión. Aunque se trata de una patología poco frecuente, esta puede generar repercusiones clínicas, físicas, psicológicas y estéticas importantes, por lo que es indispensable realizar adecuados métodos por imágenes que permitan establecer su correcto diagnóstico y manejo.

Introduction. Arteriovenous malformations are relative rare and infrequent injuries. Their main characteristic is an abnormal increase in the number of blood vessels as a result of defective vascular development. They represent a diagnostic and therapeutic challenge for the treating physician. Their incidence in the general population is around 1.5%. Some therapeutic options include selective embolization, surgical resection, or both. The purpose of this article is to report a case of an infrequent pathology and to perform a literature review on the topic to shed light on its diagnosis. Case report. The case involves a young adult patient who inquired about the presence of a mass in the right buttock with six years of evolution. It was erroneously diagnosed as a lipoma, as a result of which the patient was taken to surgery without performing preliminary diagnostic images. During surgery, the patient went into hypovolemic shock. Afterwards, the mass was documented as a profound arteriovenous malformation. Discussion. Such malformations are rarely found in the lower limbs, as in this case. These injuries may be clinically diagnosed, but knowledge or suspicion on the existence of this entity is required, because such injuries might not be clinically visible, which implies that they may go unnoticed or be erroneously diagnosed. Conclusion. Even though it is an infrequent pathology, it may have substantial clinical, physical, psychological and aesthetic implications, which implies that it is indispensable to perform adequate imaging-based procedures to enable its adequate diagnosis and management.

Introdução. As malformações arteriovenosas são lesões relativamente raras e infrequentes. São caracterizadas por apresentarem um aumento anormal do número de vasos sanguíneos como consequência de um defeito no desenvolvimento vascular. Constituem um desafio diagnóstico e terapêutico para o médico que trata. Sua incidência gira em torno de 1.5% da população geral. As opções de tratamento incluem embolização seletiva, ressecção cirúrgica ou ambas. O objetivo deste artigo é relatar um caso de patologia pouco frequente e fazer uma revisão bibliográfica sobre o assunto para lançar luz sobre seu diagnóstico. Relato de caso. Apresentamos o caso de um paciente adulto jovem que consultou por apresentar uma massa na nádega direita, de 6 anos de evolução. Isso é diagnosticado erroneamente como um lipoma, então o paciente é levado para cirurgia sem imagens diagnósticas prévias. Na cirurgia, o paciente apresenta um choque hipovolêmico. Posteriormente, a massa é documentada como uma malformação arteriovenosa profunda. Discussão. A localização dessas malformações nos membros inferiores é incomum, como no caso deste paciente. O diagnóstico dessas lesões pode ser clínico, mas requer conhecimento ou suspeita dessa entidade, pois podem ser lesões clinicamente invisíveis, o que as leva a passar despercebidas ou mal diagnosticadas. Conclusão. Embora seja uma patologia pouco frequente, pode gerar importantes repercussões clínicas, físicas, psicológicas e estéticas, pelo que é imprescindível a realização de métodos de imagem adequados para estabelecer seu correto diagnóstico e tratamento.

ABSTRACT

Abstract In the past, treatment of visceral artery aneurysms (VAAs) was exclusively surgical. These aneurysms were rarely diagnosed in elective or emergency cases. Development of imaging techniques and endovascular procedures has changed the history of the therapeutic options for this pathology. Endovascular management of VAAs has arisen to advances in endovascular techniques and has achieved high efficacy.


Resumo No passado, o tratamento de aneurismas da artéria visceral (VAAs) era exclusivamente cirúrgico e raramente diagnosticado em casos eletivos ou de emergência. O desenvolvimento de técnicas de imagem e procedimentos endovasculares mudou a história das opções terapêuticas dessa patologia. O manejo endovascular de VAAs surgiu devido ao avanço das técnicas endovasculares, o qual apresentou uma alta eficácia.

ABSTRACT

Resumo Os aneurismas das artérias pancreatoduodenais constituem uma afecção rara. Seu diagnóstico é realizado, na maioria das vezes, em situações de emergência por complicações como a rotura, a qual está associada a altas taxas de mortalidade (21-26%). A embolização do saco aneurismático é o tratamento de escolha, devido à sua alta efetividade e menor mortalidade. Neste artigo, é apresentado e discutido um caso de aneurisma de artéria pancreatoduodenal inferior com diagnóstico obtido durante investigação de sintomas gastrointestinais. O tratamento instituído foi a embolização com micromolas, com completa exclusão do aneurisma e boa evolução clínica.


Abstract Aneurysms of the pancreaticoduodenal arteries are a rare condition. In the majority of cases, diagnosis is made in emergency situations due to complications such as rupture, which is associated with high mortality rates (21-26%). Embolization of the aneurysm sac is the treatment of choice, because of its high efficacy and lower mortality. This article presents and discusses a case of inferior pancreaticoduodenal artery aneurysm that was diagnosed during investigation of gastrointestinal symptoms. The treatment provided was microcoil embolization, with complete exclusion of the aneurysm and a good clinical course.

ABSTRACT

El pseudoaneurisma arterial es la dilatación de un vaso, producto de la lesión de la pared. Es generado, principalmente, por traumatismos y, en menor medida, por patologías inflamatorias del endotelio. Se presenta como un hematoma pulsátil y doloroso. Su diagnóstico suele realizarse debido a que, ante una ecografía Doppler, se observa una imagen hipoecoica adyacente a un vaso con flujo en su interior. Su baja prevalencia, asociada a su presentación clínica variable, puede generar confusión con infecciones de piel y partes blandas o trombosis. El manejo puede ser desde la compresión extrínseca hasta la cirugía abierta, y no existen algoritmos terapéuticos en la actualidad. Se describeel caso de un paciente de 13 años con un pseudoaneurisma en una rama muscular de la arteria femoral superficial, secundario a un traumatismo cortante en el que se realizó exitosamente el abordaje endovascular con colocación de microcoils para la exclusión del saco pseudoaneurismático.


Pseudoaneurysm or 'false aneurysm' is defined as an abnormal arterial dilatation produced by an injury to its wall that does not affect the three parietal layers like in 'true' aneurysms. In general, false aneurysms are related to traumatisms and, less frequently, to inflammatory disease of vascular endothelium. Clinically, it shows a pulsatile, painful hematoma in the affected region. The initial diagnosis is usually achieved by Doppler ultrasound showing a hypoechoic image in relation to a blood vessel or its wall. Due to the low prevalence of false aneurysm, it is commonly confused with skin and soft tissue's infections or with thrombosis. There are different options of treatment, from extrinsic compression to open surgery. We describe the case of a 13-year-old patient with traumatic false aneurysm of a muscular branch of femoral artery, successfully managed with endovascular exclusion of the lesion with microcoil

ABSTRACT

Resumen Objetivo: Describir la evolución perioperatoria de pacientes sometidos a nefrectomía con y sin embolización de la arteria renal (EAR) prequirúrgica, en un hospital de alta complejidad de Medellín, Colombia. Materiales y Métodos: Observacional descriptivo retrospectivo; se incluyeron pacientes de 18-90 años con diagnóstico de tumor renal, sometidos a nefrectomía con y sin EAR prequirúrgica. Las variables cualitativas se expresaron por medio de frecuencias y proporciones, y las cuantitativas mediante medidas de tendencia central y dispersión. Resultados: Se incluyeron 71 pacientes con una media de edad de 58,1 (DE: 10,6) años, 41 eran mujeres y el 69% tenía diagnóstico de carcinoma de células claras. La media del volumen de sangrado intraoperatorio fue de 540,8 cc, y 19,7% requirió transfusión. El tiempo quirúrgico promedio fue de 2,6 horas y el 38% presentó alguna complicación, con una mortalidad total del 4,2%. Al observar comparativamente los pacientes con EAR (15 pacientes) versus aquellos sin ella (56 pacientes), se identificó un mayor volumen de sangrado intraoperatorio y la necesidad de transfusión en los primeros. Conclusión: Los pacientes sometidos a EAR presentaron un mayor volumen de sangrado, mayor frecuencia de transfusión y complicaciones postoperatorias, siendo necesario un consenso sobre su real pertinencia terapéutica.


Abstract Aim: To describe the perioperative outcomes of patients undergoing nephrectomy with and without preoperative Renal Artery Embolization (RAE) in a high-complexity hospital in Medellín, Colombia. Materials and Methods: Retrospective, descriptive and observational study; 18-90 years old patients with renal tumor diagnosis, submitted to nephrectomy with and without preoperative RAE were included. Qualitative variables were expressed by measures of frequencies and proportions, and quantitative variables were expressed by measures of central tendency and dispersion. Results: 71 patients with a media age of 58,1 (SD: 10,6) years were included, 41 were women and 69% were diagnosed with clear cell carcinoma. The blood loss volume media was 540.8 cc, and 19.7% required transfusion. The operative time media was 2.6 hours and 38% had any complication, with a total mortality of 4.2%. Comparatively observing patients with RAE (15 patients) versus patients without RAE (56 patients), a higher intraoperative blood loss and transfusion requirements were identified in the first ones. Conclusion: Patients submitted to RAE presented greater volume of bleeding, greater frequency of transfusion and post-operative complications, requiring a consensus on its real therapeutic relevance.

ABSTRACT

PURPOSE: Unstable pelvic fracture with bleeding can be fatal, with a mortality rate of up to 40%. Therefore, early detection and treatment are important in unstable pelvic trauma. We investigated the early predictive factors for possible embolization in patients with hemodynamically unstable pelvic trauma.METHODS: From January 2011 to December 2013, 46 patients with shock arrived at a single hospital within 24 hours after injury. Of them, 44 patients underwent CT scan after initial resuscitation, except for 2 who were dead on arrival. Nine patients with other organ injuries were excluded. Seventeen patients underwent embolization. A single radiologist measured the width (longest length in axial view) and length (longest length in coronal view) of pelvic hematoma on CT scans. Demographic, clinical, and radiological data were reviewed retrospectively.RESULTS: Among 35 patients with hemodynamically unstable pelvic fracture, 22 (62.9%) were men. Width (P = 0.002) and length (P = 0.006) of hematoma on CT scans were significantly different between the embolization and nonembolization groups. The predictors of embolization were width of pelvic hematoma (odds ratio [OR], 1.07; P = 0.028) and female sex (OR, 10.83; P = 0.031). The cutoff value was 3.35 cm. More embolization was performed (OR, 12.00; P = 0.003) and higher mortality was observed in patients with hematoma width >3.35 cm (OR, 4.96; P = 0.048).CONCLUSION: Patients with hemodynamically unstable pelvic trauma have a high mortality rate. CT is useful for the initial identification of the need for embolization among these patients. The width of pelvic hematoma can predict possible embolization in patients with unstable pelvic trauma.

ABSTRACT

INTRODUÇÃO: Pseudoaneurismas são geralmente resultantes de trauma sem corte levando provocando a laceração de parte da parede do vaso promovendo o extravasamento de sangue para os tecidos circundantes, seguidos por tamponamento e formação do coágulo. OBJETIVO: Apresentar um caso de pseudoaneurisma em artéria carótida externa como complicação de fratura de côndilo mandibular. RELATO DE CASO: Paciente de 18 anos de idade, vítima de acidente motociclístico compareceu à emergência do Hospital Regional do Cariri com fratura de côndilo mandibular associada à fratura de coronoide e parassínfise, evoluindo com pseudoaneurisma de artéria carótida externa e submetido à embolização seletiva. CONCLUSÃO: Ressaltamos que pseudoaneurismas da artéria carótida externa apresentam as fraturas de côndilo mandibular como fatores etiológicos raros, no entanto uma cuidadosa análise das suas características anatômicas assim como o diagnóstico precoce concorrem para a prevenção de acidentes e complicações graves nas abordagens dos traumas de face...

Introduction: Pseudoaneurysms are usually the result of blunt trauma leading to laceration of part of the vessel wall promoting extravasation of blood into surrounding tissues followed by tamponade and clot formation. Purpose: To present a case of external carotid artery pseudoaneurysm as a complication of mandibular condyle fracture. Case report: An 18-year-old patient, a motorcycle accident victim, attended the emergency of the Cariri Regional Hospital with a mandibular condyle fracture associated with a coronoid fracture and a parasymphysis, evolving with external carotid artery pseudoaneurysm and submitted to selective embolization. Conclusion: We emphasize that pseudoaneurysms of the external carotid artery present mandibular condyle fractures as rare etiological factors, however a careful analysis of their anatomical characteristics as well as early diagnosis contributes to the prevention of accidents and serious complications in the face trauma approaches...

ABSTRACT

Abstract Angiomyolipomas (AMLs) are rare benign tumors derived from mesenchymal tissue and composed of varying degrees of adipose tissue, muscle and blood vessels. Renal AMLs (RAMLs) are the result of a sporadic event, and, in most of cases, the diagnosis is usually incidental, but hemorrhage and shock may be present. During pregnancy, the size of AMLs may increase and they may rupture, probably due to the high expression of hormone receptors, and the increase in maternal circulation and abdominal pressure. The authors present a case of a woman with ruptured RAML submitted to urgent endovascular treatment four days after giving birth by cesarean section.


Resumo Angiomiolipomas (AMLs) são tumores benignos raros derivados do tecido mesenquimal, compostos em graus variados de tecido adiposo, muscular e de vasos sanguíneos. Os AMLs renais (AMLRs) resultam de um evento esporádico e, na maioria dos casos, o diagnóstico costuma ser fortuito, mas quadros de hemorragia e choque podem estar presentes.

ABSTRACT

The treatment options available for patients with hepatocellular carcinoma (HCC) with portal vein invasion (PVI) include sorafenib, transarterial radioembolization (TARE), radiation therapy (RT), transarterial chemoembolization with RT, and proton beam irradiation. Herein, we present a case of HCC with segmental PVI that was managed via TARE. The patient had a 4 cm HCC that invaded the segment VIII portal vein branch without extrahepatic spread. Liver function was Child-Pugh grade A, and performance status was good. TARE was performed without any adverse events, and a radiological complete response (CR) was achieved. Thereafter, the patient was followed-up every 3–6 months without any further treatment, and the CR was maintained for >3 years. Therefore, TARE may be a useful alternative therapeutic option for patients with HCC exhibiting segmental PVI.

ABSTRACT

BACKGROUND/AIMS: We aimed to determine the relationship between the safety margin of an embolized area and local tumor recurrence (LTR) of patients with hepatocellular carcinoma (HCC) who underwent superselective transarterial chemoembolization (TACE). METHODS: The medical records of 77 HCC patients with 109 HCC nodules who underwent superselective TACE were retrospectively analyzed for LTR. Univariate and multivariate analyses were performed for 16 potential factors using Cox proportional hazard regression. Iodized oil deposition on cone-beam computed tomography (CBCT) imaging was divided into three grades: A=complete tumor staining and complete circumferential safety margin, B=complete tumor staining but incomplete safety margin, C=incomplete tumor staining. The effect of a safety margin on LTR was evaluated by comparison between grade A and B group. RESULTS: Univariate and multivariate analyses revealed that grade A iodized oil deposition and portal vein visualization were the only two independent significant factors of LTR (P<0.001 and P=0.029, respectively). The 12- and 24-month LTR rates of tumors for grade A (n=62), grade B (n=30), and grade C (n=17) were 16% vs. 41% vs. 100% and 16% vs. 61% vs. 100%, respectively (P<0.001). The tumors in the grade A group had a 75% risk reduction in LTR (odds ratio, 0.25; 95% confidence interval, 0.10 to 0.64; P=0.004) compared to the grade B group. CONCLUSIONS: LTR was significantly lower when a greater degree of iodized oil deposition occurred with a complete circumferential safety margin. In superselective TACE, the safety margin of the embolized areas using intraprocedural CBCT affected LTR in HCC patients.

ABSTRACT

PURPOSE: Recent studies have analyzed the short-term clinical outcomes of ndovascular management. However, the long-term outcomes are unknown. This study aimed to investigate clinical outcomes after endovascular management for ruptured pseudoaneurysm in patients after pancreaticoduodenectomy (PD). METHODS: The medical records of 2,783 patients who underwent PD were retrospectively reviewed at a single center. Of 62 patients who received intervention after pseudonaeurysm rupture, 57 patients (91.9%) experienced eventual success of hemostasis. The patients were composed as follows: (embolization only [EMB], n = 30), (stent-graft placement only [STENT], n = 19) and (both embolization and stent-graft placement simultaneously or different times [EMB + STENT], n = 8). Long-term complications were defined as events that occur more than 30 days after the last successful endovascular treatment. RESULTS: Among 57 patients, short-term stent-graft related complications developed in 3 patients (5.3%) and clinical complication developed in 18 patients (31.5%). Nine (15.8%) had long-term stent-graft related complications, which involved partial thrombosis in 5 cases, occlusion in 3 cases and migration in 1 case. Except for 1 death, the remaining 8 cases did not experience clinical complications. The stent graft primary patency rate was 88.9% after 1 month, 84.2% after 1 year, and 63.2% after 2 years. Of 57 patients, 30 days mortality occurred in 8 patients (14.0%). CONCLUSION: After recovery from initial complication, most of patients did not experience fatal clinical complication during long-term follow-up. Endovascular management is an effective and safe management of pseudoaneurysm rupture after PD in terms of long-term safety.

ABSTRACT

No endoleak tipo 1A, a endoprótese não sela completamente o colo do aneurisma proximal, e o fluxo arterial está presente entre a parede do colo aórtico e o material do implante. Este é um relato de um caso no qual foi utilizada embolização com molas, associado a uma revisão de literatura (PubMed, LILACS e SciELO). Foram pesquisados artigos publicados nos últimos 5 anos com os descritores "endoleak 1A", "coil embolization" e "treatment", combinados de formas aleatórias, sendo encontrados 25 artigos. O tipo 1A ocorre em 1,1% dos pacientes após 30 dias do implante. O tratamento consiste em aumentar a vedação do implante proximal, principalmente com o uso de stents e balões para alargar a zona de aterragem ou aumentar a força radial do implante. Alguns trabalhos sugerem técnicas de embolização com cianoacrilato, cola de fibrina e uso de Onyx, mostrando taxas de sucesso superiores a 97%. Contudo, a correção de endoleaks tipo 1A mediante embolização com molas é pouco descrita


In a type 1A endoleak, the endograft is unable to fully seal the proximal aneurysm neck and blood flow leaks between the wall of the aortic neck and the graft material. This article reports a case in which coil embolization was used and presents a literature review (PubMed, LILACS, and SciELO). Searches were run for articles published in the past 5 years using the descriptors "endoleak 1A", "coil embolization," and "treatment". Type 1A endoleak occurs in 1.1% of patients within 30 days of graft placement. Treatment of an endoleak is obligatory and usually consists of sealing the proximal graft neck using stents and balloons to expand the landing zone or to increase the radial force of the graft. Some studies have suggested using embolization techniques with cyanoacrylate, fibrin glue, and Onyx, demonstrating success rates that exceed 97%.

ABSTRACT

Fístulas arteriovenosas (FAVs) renais adquiridas são raras, correspondendo a uma conexão anômala entre o sistema arterial e o sistema venoso. As FAVs renais se dividem em três grandes grupos: idiopáticas, congênitas e adquiridas, sendo as últimas as mais comuns. Atualmente, têm incidência aumentada em decorrência do crescente número de biópsias renais. Apesar de, atualmente, o procedimento de biópsia renal ser relativamente seguro, ele carrega como complicação a formação de FAV no território vascular renal. O tratamento de FAV renal é amplamente discutido na literatura e diversas modalidades terapêuticas podem ser aplicadas. Apresentamos um caso de FAV pós-biópsia renal que foi submetida a tratamento endovascular com sucesso mediante embolização com molas


Acquired renal arteriovenous fistulas (AVF) are rare conditions in which an anomalous connection arises between the arterial and venous systems. Renal AVFs can be classified into three main groups: idiopathic, congenital, and acquired, the last of which are the most common. Incidence has been increasing, due to the growing number of renal biopsies. Although the renal biopsy procedure is relatively safe nowadays, one possible complication is formation of an AVF in the renal vascular territory. Treatment of renal AVF is widely discussed in the literature and a variety of treatment methods can be employed. We report a case of arteriovenous fistula after renal biopsy that was successfully treated with endovascular coil embolization

ABSTRACT

O sequestro pulmonar refere-se à anomalia congênita definida por massa de parênquima pulmonar não funcionante. É dividido pela existência de envoltório pleural próprio em intralobar, representando cerca de 75% dos casos, ou extralobar, responsável pelos 25% restantes. O diagnóstico é feito através de radiografia e confirmado com tomografia computadorizada, ressonância nuclear magnética e arteriografia. Tradicionalmente, o tratamento proposto é cirúrgico, mas a técnica endovascular tem apresentado bons resultados. É relatado o caso de uma mulher, 29 anos, com quadro clínico de pneumonias de repetição desde os 5 anos. A tomografia de tórax revelou malformação vascular em região inferior de pulmão direito. O tratamento vascular foi realizado através de embolização do ramo anômalo


Pulmonary sequestration is a congenital anomaly defined as a nonfunctioning mass of lung parenchyma. Presence of an independent pleural envelope classifies it as intralobar, accounting for approximately 75% of the cases, while absence classifies cases as extralobar, accounting for the remaining 25%. Diagnosis is made through radiography and confirmed by computed tomography, magnetic resonance, or angiography. The traditional treatment is open surgical repair, but endovascular techniques have been used, with good results. We report the case of a 29-year-old-woman presenting with recurrent pneumonia for 5 years. A CT scan of the chest revealed poor vascular formation in the lower region of the right lung. The pulmonary sequestration was treated by embolization of the anomalous branch

ABSTRACT

Proliferative angiopathy (PA) is a rare cerebral vascular disease in which anomalous vessels continually recruit additional feeder arteries, amid a functional brain parenchyma. We report the case of a young woman with progressive history of headache, motor deficit, seizures and drowsiness. She received a misdiagnosis of brain arteriovenous malformation (AVM) and evolved with dysarthria and cognitive decline after an unsuccessful embolization performed at another institution. We opted for conservative treatment with periodic control by imaging tests. Proliferative angiopathy differs in natural history, prognosis, histopathology and treatment of the usual AVMs. Endovascular procedures aggravate the neurological deficits, which are usually progressive and tend to worsen over time.


A angiopatia proliferativa (AP) é uma doença vascular cerebral rara em que vasos anômalos recrutam continuamente artérias nutridoras adicionais em um parênquima cerebral normal. Relatamos um caso de uma mulher jovem com história progressiva de cefaleia, déficit motor, convulsões e sonolência. Ela recebeu um diagnóstico incorreto da malformação arteriovenosa (MAV) cerebral e evoluiu com disartria e declínio cognitivo após uma embolização malsucedida realizada em outra instituição. Optamos pelo tratamento conservador com controle periódico por testes de imagem. A AP difere das MAVs usuais em relação a história natural, prognóstico, histopatologia e tratamento. Os procedimentos endovasculares agravam os déficits neurológicos, que geralmente são progressivos e tendem a piorar ao longo do tempo.

ABSTRACT

Objetivos: Determinar la eficacia de la embolización de las arterias prostáticas en el tratamiento de los pacientes con síntomas del tracto urinario bajo asociados a hiperplasia prostática benigna. Material y métodos: Estudio descriptivo, tipo reporte de casos, prospectivo. Se realizó embolización de arterias prostáticas (EAP) a 10 pacientes, 7 de los cuales tenían síntomas del tracto urinario bajo asociado a hiperplasia benigna de próstata (STUB/HBP) moderados y severos, refractarios a tratamiento médico durante 6 meses y 3 portadores de sonda vesical permanente; la edad promedio fue 69,4 ± 8,04 años. Se evaluaron a los pacientes antes de la EAP (tiempo 0), y a los meses 1, 3 y 6; el éxito se valoró por: disminución del volumen de la próstata (VP): >10%, mejora del puntaje internacional de síntomas prostáticos (IPSS), flujo urinario máximo (Q):>15 ml/seg, índice internacional de función eréctil (IIEF)sin variación o aumento en 10%,disminución del residuo post-miccional (RPM)>20% y efectos adversos: ≤2 eventos. Resultados: La EAP fue técnicamente exitosa en el 100% de pacientes. Las tasas de éxito clínico al mes 6 fueron: Disminución del VP en 40% (p=0,0009), APE en 15% (p=0,0464) y el IPSS mejoró en 63% (p=0,0010). No hubo variaciones significativas en el IIEF-15 (reducción del puntaje en 12,1% (p=0,1157)), el Q se incrementó máx en 80% (p=0,1088) y en la reducción del RPM (se redujo en 25% (p= 0,6177)). No se presentó complicaciones mayores durante el estudio. Conclusiones: La EAP es una opción de tratamiento para mejorar los parámetros críticos de los STUB/HBP sin afectar la función sexual. (AU)


Objectives: To determine the efficacy of prostatic artery embolization in the treatment of urinary symptoms associated to benign prostatic hyperplasia. Methods: A descriptive and prospective case report study was conducted. Embolization of prostatic arteries (EPS) was carried-out in 10 patients, 7 of whom had moderate and severe urinary tract symptoms to associated to benign prostatic hyperplasia (UTS/BPH) refractory to medical treatment during 6 months, 3 were using a permanent urinary catheter. Mean age was 69.4 ± 8.04 years. Patients were evaluated at time 0 of EPS and at 1, 3 and 6 months after. Success was defined as reduction in prostatic volume (PV) >10%; improvement in the international score of prostatic symptoms (ISPS); maximum urinary output (Qmáx) > 15 ml/ sec; international index of erectile function (IIEF) with no variation or increase in 10%; reduction on post void residual (PVR) >20% and ≤2 medical events. Results: The EPS was technically successful in 100% of patients. The evaluation of clinical parameters at 6 months was as follows: 40% reduction in PV (p=0.0009; the ISPS improved in 63% (p=0.0010). No variation was observed in the IIEF-15 (12.1% reduction (p=0.1157)); the Qmáx increased in 80% (p=0.1088), and a 25% reduction in PVR (p= 0.6177)). No complications were observed during the procedure. Conclusions: EPS is an option to improve clinical parameters of UTS/BPH without affecting the sexual function. No major complications were observed. (AU)

ABSTRACT

Posterior fossa epidural hematoma (EDH) is uncommon, but the related clinical deterioration can occur suddenly. Accompanying venous sinus injury and lacerations are associated with 40% to 80% mortality. The authors present one clinical case of a patient with posterior fossa EDH from transverse sinus bleeding. A 57-year-old male was injured after falling while working. He was taken to the hospital, where computed tomography scans of his brain revealed a right posterior temporal and cerebellar EDH with a right temporo-occipital fracture. He underwent a right parieto-occipital craniotomy, incorporating the fracture line. Longitudinal laceration of the right transverse sinus extending to the sigmoid sinus with profuse bleeding was identified. Four gauzes were inserted in the epidural space for tamponade of the injured sinus. Conventional angiography and coil embolization for the injured sinus were immediately performed. Subsequently, the patient was transferred to the operating room, wherein staff members removed the gauzes and remnant hematoma. Based on this experience, the authors recommend that for posterior fossa EDH from transverse sinus bleeding, bleeding control should be performed by gauze packing and endovascular treatment.

ABSTRACT

Transcatheter arterial embolization using N-butyl-2-cyanoacrylate (NBCA) for gastrointestinal arterial bleeding enables higher cessation rate and lower recurrent bleeding rate compared with conventional embolic materials including gelatin sponge, metallic coil, and polyvinyl alcohol (PVA) particle. Glue embolization is particularly effective in patients with coagulopathy. Even in the lower gastrointestinal tract, ischemic bowel complications by glue embolization are comparable to other agents. Glue embolization is also effective for arterial esophageal bleeding without any serious ischemic complications although the anatomy of the esophageal artery is complex and varied. For bleeding after abdominal surgery such as pancreaticoduodenectomy or hepatic lobectomy, interventional radiologists should be careful with indicating glue embolization because the presence of fewer collateral vessels can easily result in serious ischemic complications. Modified glue such as Glubran 2 (NBCA associated with methacryloxyfulfolane) can reduce the risk of ischemic complication due to its less thermal reaction, but the outcomes seem unsatisfactory.
