Deslocamento espontâneo do núcleo do cristalino para câmara anterior / Spontaneous displacement of the lens nucleus into the anterior chamber

RESUMO Ao longo da vida, o cristalino produz novas fibras dispostas de forma concêntrica, que aumentam seu diâmetro anteroposterior e peso, tornando seu núcleo mais compacto e endurecido. A catarata hipermadura é uma forma de progressão avançada dessa proliferação de fibras, que pode desencadear uma variedade de complicações. A ruptura espontânea da cápsula anterior do cristalino, evoluindo com deslocamento anterior do núcleo, é uma complicação rara e com poucos casos publicados na literatura. Descrevemos o caso de uma paciente do sexo feminino, 68 anos, que apresentou ruptura espontânea da cápsula anterior do cristalino com deslocamento anterior do núcleo em olho esquerdo sem histórico de trauma ocular. A paciente foi submetida à facoemulsificação do cristalino e ao controle da pressão intraocular, evoluindo com melhora do quadro clínico.

ABSTRACT Throughout life, the lens produces new fibers arranged concentrically, which increase its anteroposterior diameter and weight, making its nucleus more compact and hardened. Hypermature cataract is an advanced stage of this fiber proliferation, which can trigger a variety of complications. Spontaneous rupture of the anterior lens capsule evolving with anterior displacement of the nucleus is a rare complication, with few cases published in the literature. We describe the case of a 68-year-old female patient, who presented spontaneous rupture of the anterior lens capsule with anterior displacement of the nucleus in the left eye, without a history of ocular trauma. The patient underwent phacoemulsification and clinical control of intraocular pressure, improving her condition.

Embarazo ectópico roto con fracción beta de la hormona gonadotropina coriónica humana negativa: reporte de caso / Ruptured ectopic pregnancy with negative human chorionic gonadotropin hormone beta fraction: case report

Resumen El embarazo ectópico roto es una emergencia quirúrgica cuyo diagnóstico, gracias a la interrelación de la cuantificación de la fracción beta de la hormona gonadotropina coriónica humana (HCG-β) y los hallazgos ultrasonográficos, se ha hecho más preciso. Sin embargo, el diagnóstico se vuelve difícil cuando clínicamente se encuentran datos sugestivos de embarazo ectópico con una HCG-β negativa. Presentamos el caso de una mujer de 25 años acude a valoración por referir 12,2 semanas de retraso menstrual, asociado a sangrado transvaginal y signos de irritación peritoneal, que cuenta con HCG-β negativa (< 5 mUI/ml). Se realizó un rastreo ultrasonográfico encontrando abundante líquido libre en cavidad, sin evidencia de embarazo intrauterino. Ante la alta sospecha de embarazo ectópico se realizó laparotomía exploradora, encontrando hallazgos sugestivos de embarazo ectópico roto, y se realizó salpingectomía. Finalmente, en el estudio posoperatorio se confirmó por histopatología un embarazo ectópico roto. Existen muy pocos reportes en la literatura internacional de pacientes con características clínicas de embarazo ectópico roto, con HCG-β negativa. Es importante la difusión de este tipo de casos con la finalidad de mejorar los abordajes diagnósticos y no restar importancia ante la sospecha clínica, a pesar de presentar una HCG-β negativa.

Abstract Broken ectopic pregnancy is a surgical emergency that due to the relation between the serum quantification of the of the beta subunit of human chorionic gonadotropin (β-HCG) and the ultrasonographic findings, there have been improvements to reach a precise diagnosis. However, there are very few reported cases in the literature where a broken ectopic pregnancy is described with negative serum results in β-HCG. We present a case report of a 25-year-old patient came to the evaluation for referring 12.2 weeks of menstrual delay, associated with transvaginal bleeding and data of peritoneal irritation, she had a negative β-HCG fraction (< 5 mIU/ml). A scan was performed ultrasound finding abundant free fluid in the cavity, without evidence of intrauterine pregnancy. Given the high suspicion of ectopic pregnancy, an exploratory laparotomy was performed, finding findings suggestive of a ruptured ectopic pregnancy, a salpingectomy was performed. Finally, in the postoperative study, a ruptured ectopic pregnancy was confirmed by histopathology. There are very few reported internationally were found a patient with clinical characteristics of broken ectopic pregnancy, with a β-HCG negative. It is important the scientific diffusion of this type of cases with the purpose of improving the diagnostic approaches and not underestimating importance to the clinical suspicion, despite presenting negative β-HCG results.

Rotura espontánea de quiste hepático simple: éxito del tratamiento conservador / Spontaneous rupture of a simple liver cyst: success of a conservative approach

RESUMEN Los quistes hepáticos simples (QHS) son las lesiones hepáticas más frecuentes. Cursan habitualmente asintomáticas, aunque cuando alcanzan gran tamaño pueden causar síntomas. El objetivo del presente artículo es presentar una complicación excepcional de los QHS. Presentamos a una mujer de 61 años con historia de QHS múltiples que acude a Urgencias por dolor abdominal brusco sin antecedente traumático. Ante la sospecha de rotura quística espontánea, se realiza tomografía computarizada (TC) abdominal que confirma el diagnóstico. Se decide tratamiento conservador con buena evolución. Tras el episodio agudo es intervenida quirúrgicamente realizándose destechamiento de los quistes. a rotura de los QHS es una complicación excepcional que habitualmente cursa con dolor abdominal. Debido a su baja frecuencia no existe un tratamiento estándar. Se acepta que el tratamiento conservador es una buena opción en pacientes sin signos de peritonitis, mientras que la cirugía urgente está indicada en pacientes con abdomen agudo.

ABSTRACT Simple liver cysts (SLC) are the most common liver tumors. They are usually asymptomatic but large cysts may produce symptoms. The aim of this article is to report a rare complication of SLC. We report the case of a 61-year-old woman with a history of multiple SLCs who sought medical care due to sudden abdominal pain not associated with trauma. A probable diagnosis of spontaneous rupture was made, and the patient underwent computed tomography (CT) scan of the abdomen which confirmed the suspicion. Conservative treatment was decided, with favorable outcome. After the acute episode the patient underwent surgery and the cysts were unroofed. Rupture of SLC is a rare complication that usually presents with abdominal pain. There is no standard of care due to the low incidence of this complication. The conservative approach is a good option in patients without signs of peritonitis, while emergency surgery is indicated in patients with acute abdomen.

Rotura esplénica espontánea secundaria a mononucleosis infecciosa / Spontaneous splenic rupture secondary to infectious mononucleosis

Resumen La rotura esplénica es una complicación rara pero potencialmente fatal de la mononucleosis infecciosa. Presentamos el caso de una mujer de 18 años que consultó por dolor abdominal de siete días de evolución, asociado a fiebre y pérdida de conciencia brusca y transitoria. En el hemograma presentaba una anemia y linfocitosis. Se realizó una tomografía computada de abdomen y pelvis que mostró un extenso hemoperitoneo, con el bazo rodeado por un hematoma, y numerosas adenopatías cervicales, mesentéricas e inguinales. Se efectuó una laparoscopía que demostró abundante hemoperitoneo con coágulos a lo largo de la gotera parietocólica izquierda. El bazo estaba completamente decapsulado y rodeado por una colección hemática con sangrado en napa. Se realizó una esplenectomía total sin complicaciones. El estudio histopatológico esplénico mostró una atenuación de la pulpa blanca y expansión de la pulpa roja con áreas de hemorragia y necrosis. La IgM anti-cápside para virus de Epstein Barr fue positiva. La paciente evolucionó de manera favorable.

Abstract Splenic rupture is a rare but potentially fatal complication of infectious mononucleosis. We report the case of an 18-year-old woman, who presented a 7-day history of abdominal pain, sudden temporary loss of consciousness and fever. Admission blood tests showed anemia, and lymphocytosis. Computed tomography of the abdomen and pelvis demonstrated extensive hemoperitoneum and numerous cervical, mesenteric and inguinal enlarged lymph nodes. Laparoscopy was performed and abundant hemoperitoneum with blood clots along the left parietocolic gutter were observed. The spleen was completely decapsulated and surrounded by a hematoma and the subcapsular tissue was bleeding. Total splenectomy was performed without complications. Splenic histology demonstrated white pulp attenuation and expansion of the red pulp with focal hemorrhage and necrosis. IgM anti-viral capsid antigen of Epstein Barr virus was positive. The patient had a satisfactory recovery.

Hematocele y hemoperitoneo como manifestación inicial de carcinoma hepatocelular: caso clínico / Hematocele and hemoperitoneum as initial manifestation of hepatocellular carcinoma: report of one case

Hepatocellular carcinoma (HCC) rupture is a rare complication, with a higher prevalence in countries of Asia and Europe. Its clinical manifestations can be nonspecific, from abdominal pain and bloating to hemodynamic involvement. We report a 70-year-old male patient with a history of chronic liver disease, presenting with an enlargement and ecchymosis of the scrotum, associated with abdominal bloating. The initial abdominal ultrasound study showed increased liquid content in the scrotal sac and regional edema. A CT of the abdomen and pelvis showed a liver mass with characteristics of hepatocellular carcinoma, associated with extensive hemoperitoneum that drained into the scrotal sac. The patient was treated with embolization of the right hepatic artery and later with surgical resection of the tumor mass, with a good clinical evolution.

Manejo de la ruptura hepática espontánea en el síndrome de HELLP / Management of spontaneous hepatic rupture in HELLP syndrome

Introducción. El síndrome de HELLP es una variante grave de la preeclampsia, con una baja incidencia, entre el 0,5-0,9 % de todos los embarazos. La ruptura hepática espontánea en el embarazo es infrecuente, presenta una alta mortalidad, y se ha relacionado con hemangiomas hepáticos, coriocarcinoma y síndrome de HELLP. Caso clínico. Mujer de 29 años con embarazo de 34,3 semanas, con actividad uterina progresiva, sufrimiento fetal agudo y hallazgos compatibles con síndrome de HELLP. Se practicó cesárea de urgencia encontrando hemoperitoneo y ruptura hepática del lóbulo derecho, por lo que se realizó empaquetamiento abdominal y posterior reintervención quirúrgica. Discusión. La ruptura hepática espontánea en el embarazo es una entidad infrecuente y potencialmente mortal. Es esencial un alto nivel de sospecha para realizar el diagnóstico y la rápida intervención. Requiere un manejo multidisciplinario para un resultado exitoso. Se han descrito múltiples tratamientos que dependen de las manifestaciones clínicas y extensión de la lesión, pero es claro que la laparotomía primaria y el taponamiento constituyen la mejor elección ante el hallazgo intraoperatorio.

Introduction. HELLP syndrome is a severe variant of preeclampsia with a low incidence, between 0.5-0.9% of all pregnancies. Spontaneous hepatic rupture in pregnancy is rare, has a high mortality, and has been associated with hepatic hemangiomas, choriocarcinoma, and HELLP syndrome. Clinical case. 29-year-old woman with a 34.3-week pregnancy, with progressive uterine activity and acute fetal distress and findings compatible with HELLP syndrome. An emergency cesarean section was performed, finding hemoperitoneum and hepatic rupture of the right lobe, performing abdominal packing and subsequent surgical reoperation. Discussion. Spontaneous liver rupture in pregnancy is a rare and potentially fatal entity. A high level of suspicion is essential to make the diagnosis and prompt intervention. It requires multidisciplinary management for a successful outcome. Multiple treatments have been described that depend on the clinical manifestations and extent of the lesion, but it is clear that primary laparotomy and packing constitute the best choice before the intraoperative finding.

Definition of tumor rupture in gastrointestinal stromal tumor / 中华胃肠外科杂志

Tumor rupture is a common clinical event in the process of tumorigenesis, progression, diagnosis and treatment of gastrointestinal stromal tumor, which is closely associated with tumor recurrence, metastasis and poor prognosis. Tumor rupture may be associated with some intrinsic biological aggressiveness qualities, such as large tumor size, high mitotic count, and KIT exon 11 deletion mutations involving codons 557 and 558, and may be relatively more frequent with small intestine GIST and excellent response to imatinib neoadjuvant therapy resulting in tumor tissue rapid liquefacient and necrosis. The triggering factors involve sudden increase in abdominal pressure, external pressure, collision and improper surgical operation, etc. Tumor rupture is considered as an important risk factor of recurrence after macroscopically complete resection of tumor, and an indication for determining interval or even lifelong adjuvant therapy with imatinib according to guidelines. However, there is no consensus or universally accepted definition of tumor rupture, and, consequently, its incidence varies greatly across reported series and lacks detailed epidemiological data. Without pre-defined criteria, it is difficult to assess the clinical significance of rupture. We reviewed the relevant literature and international guidelines, and generally divided tumor rupture into spontaneous rupture and iatrogenic rupture. Based on the Oslo criteria, we proposed the following six definitions for tumor rupture: (1) tumor fracture or spillage; (2) blood-stained ascites; (3) gastrointestinal perforation at the tumor site; (4) microscopic infiltration of an adjacent organ; (5) intralesional dissection or piecemeal resection; (6) incisional biopsy. The following types of minor defects of tumor integrity should not be defined as rupture: (1) mucosal defects or spillage contained within the gastrointestinal lumen; (2) microscopic tumor penetration of the peritoneum or iatrogenic damage only to the serosa; (3) uncomplicated transperitoneal needle biopsy; (4) R1 resection. In addition, we further emphasize the importance of identifying risk factors of tumor rupture, prevention and positive intervention.

Resultado imediato do tratamento endovascular com stents paralelos do aneurisma roto justarrenal / Immediate outcome of endovascular treatment of ruptured juxtarenal aneurysm with parallel stents

Resumo A ruptura do aneurisma de aorta abdominal é um evento com alta mortalidade, e o seu tratamento nesses casos é uma emergência médica. O tratamento endovascular desses aneurismas tem se estabelecido como uma alternativa minimamente invasiva à cirurgia aberta clássica, tornando-se a opção de primeira escolha. Contudo, 20 a 50% dos pacientes portadores de aneurisma de aorta abdominal não apresentam anatomia favorável para o tratamento endovascular devido à presença de colo curto ou pelo acometimento de ramos viscerais pelo aneurisma. Relatamos um caso de uma paciente de 70 anos submetida à correção endovascular de aneurisma roto justarrenal com implante de stents paralelos para as renais (técnica de chaminé). São apresentados dados clínicos e detalhes do procedimento. O sucesso técnico foi obtido e não houve relato de complicações pós-operatórias.

Abstract Rupture of an abdominal aortic aneurysm is an event with a high mortality rate and treatment is a medical emergency. Endovascular treatment of these aneurysms has become established as a minimally invasive alternative to classical open surgery and is now the first-choice option. However, 20 to 50% of patients with abdominal aortic aneurysms do not have anatomy favorable for endovascular treatment because of a short aneurysm neck or because visceral branches are involved by the aneurysm. We report the case of a 70-year-old patient who underwent endovascular repair of a ruptured juxtarenal aneurysm with deployment of parallel stents in the renal arteries (in a chimney technique). Clinical data and details of the procedure are reported. Technical success was achieved and there were no postoperative complications.

Ruptura uterina em primípara: relato de caso / Uterine rupture in primiparous: case report

Introdução: A ruptura uterina é uma complicação grave, devido ao risco de morte materna e perinatal. Em países desenvolvidos, essa complicação obstétrica afeta 3,5/1.000 mulheres com cesárea anterior e 6/10.000 grávidas sem antecedentes da operação, sendo a incisão cesariana prévia a etiologia principal. Relato de Caso: Gestante, 38 anos, G1P0A0, com idade gestacional de 35 semanas e 5 dias, deu entrada na maternidade em trabalho de parto prematuro. Ao exame físico apresentando 3 metrossístoles em 10min/30" 30" 35", colo uterino amolecido e fino, com dilatação de 3 cm, exame especular com presença de líquido amniótico claro, bolsa rota há 6 horas e pequeno sangramento há 20 minutos. Foi indicado parto cesáreo devido ao histórico de luxação de quadril. O diagnóstico de ruptura uterina foi realizado durante o parto operatório, com visualização de partes fetais. O caso teve evolução benigna para a m ãe e o recém-nascido, sem a ocorrência de complicações ou sequelas, ambos tiveram alta hospitalar em perfeitas condições de saúde. Discussão: Configurou-se uma ruptura uterina completa espontânea no terceiro trimestre gestacional, sem quaisquer fatores de risco subjacentes identificáveis, exceto pela idade materna avançada (maior que 35 anos). Conclusão: Este relato contribui para um número limitado de ocorrências descritas que envolvem ruptura espontânea de um útero sem cicatriz prévia em uma paciente primigesta.

Introduction: Uterine rupture is a serious complication, due to the risk of maternal and perinatal death. In developed countries, this obstetric complication affects 3.5/1,000 women with previous cesarean section and 6/10,000 pregnant women with no story of the operation, with the previous cesarean section being the main etiology. Case Report: Pregnant woman, 38 years old, G1P0A0, with a gestational age of 35 weeks and 5 days, was admitted to the maternity ward in premature labor. At the physical examination reinforced 3 metrosystoles in 10min/30" 30" 35", soft and thin cervix, with 3cm dilation, specular examination with the presence of clear liquid with lumps, broken bag for 6 hours and minor bleeding for 20 minutes. Cesarean delivery is indicated due to a story of hip dislocation. The diagnosis of uterine rupture was performed during operative delivery, with visualization of fetal parts. The case had a benign evolution for the mother and the newborn, without the occurrence of complications or sequelae, both were discharged from hospital in perfect health conditions. Discussion: A complete spontaneous uterine rupture occurred in the third trimester of pregnancy, without any identifiable underlying risk factors, except for advanced maternal age (over 35 years). Conclusion: This report contributes to a limited number of previous events that involve spontaneous rupture of a uterus without previous scarring in a primigravid patient.

Emergency endovascular repair of aortoiliac aneurysms in COVID-19 times / Tratamento endovascular das emergências dos aneurismas aortoilíacos em tempos de COVID-19

Abstract In this paper, we describe a case series of four patients who were admitted with emergencies related to aortic aneurysms over a 3-day period and were treated with endovascular repair. The first patient was an 81-year-old female with a history of abdominal pain and a ruptured aortic aneurysm diagnosed by AngioCT-scan. The second patient was a 63-year-old male with a history of oral digestive bleeding and an AngioCT-scan showing an aortoenteric fistula. The third patient was a 77-year-old female with sudden-onset abdominal pain and ruptured right common iliac aneurysm. The fourth patient presented with abdominal pain and an AngioCT-scan showed aortic rupture. All four patients were discharged with no major complications or surgical mortality. These case series show that despite the Covid-19 pandemic situation, since elective surgeries decreased, vascular emergencies have increased.

Resumo Relatamos uma série de casos de quatro pacientes consecutivos, admitidos com emergências relacionadas a aneurismas aortoilíacos em um período de 3 dias e submetidos a tratamento endovascular. A primeira paciente, do sexo feminino, com 81 anos e com histórico de aneurisma da aorta, apresentou dor abdominal iniciada nos últimos 12 dias. O segundo paciente era do sexo masculino, com 63 anos e foi admitido com hematêmese 3 dias antes da admissão, com angiotomografia demonstrando fistula aortoentérica. A terceira paciente, do sexo feminino e com 77 anos, foi admitida com quadro de ruptura de aneurisma da artéria ilíaca comum direita. O quarto paciente consecutivo apresentou dor abdominal iniciada 2 semanas antes da internação e aneurisma roto da aorta. Todos os quatro pacientes apresentaram emergências aortoilíacas e receberam alta sem complicações maiores ou mortalidade cirúrgica. O relato desta série de casos demonstra que, apesar da situação pandêmica da COVID-19, uma vez que as cirurgias eletivas diminuíram, as urgências vasculares aumentaram.

Disnea por rotura espontánea traqueal en ancianos / Dyspnea due to spontaneous tracheal rupture in the elderly

Tracheal rupture is an infrequent complication with high morbidity and mortality, of multifactorial etiology, being orotracheal intubation its main cause. Spontaneous tracheal rupture usually occurs after severe coughing and/or vomiting over a weakened trachea. The diagnosis is non-specific, based on highly suggestive signs and symptoms such as subcutaneous emphysema, pneumomediastinum and respiratory distress, and its confirmation requires the performance of a bronchoscopy. The location and extent of the rupture determines the clinic. This implies the importance of an early diagnosis to avoid a poor prognosis. We present the case of an elderly male patient with a spontaneous tracheal rupture without apparent cause

La rotura traqueal es una complicación infrecuente de etiología multifactorial, con una elevada morbimortalidad, la intubación orotraqueal es su principal causa. La rotura traqueal espontánea suele producirse luego de toser o presentar vómitos intensos, sobre una tráquea debilitada. El diagnóstico es inespecífico, se basa en signos y síntomas altamente sugestivos como enfisema subcutáneo, neumomediastínico y dificultad respiratoria y su confirmación exige la realización de una broncoscopia. La localización y extensión de la rotura determinan la clínica. Esto implica la importancia del diagnóstico precoz para evitar un pronóstico infausto. Se presenta el caso de un paciente varón, de edad avanzada. con una rotura espontánea traqueal sin causa aparente

Massive retroperitoneal haematoma because of renal cyst rupture, report of a case / Hematoma retroperitoneal masivo por ruptura de quiste renal, reporte de caso

We report the case of an 86-year-old adult man who, as a pedestrian, is hit by a motorcycle, suffering polytrauma; in initial care, he refers to thoraco-abdominal pain and subsequently neurological deterioration. Assessed by a neurosurgeon and general surgeon, a right chest tube is placed and a laparoscopy is performed where there is little bleeding from the abdominal cavity. It shows deterioration of its general state and dies in respiratory failure. During the necropsy procedure there is subarachnoid hemorrhage and cerebral herniation, rib fractures and pneumonic consolidation, a massive retroperitoneal hematoma is observed due to rupture of simple renal cyst.

Reportamos el caso de un hombre de 86 años que, siendo peatón, es atropellado por una motocicleta, sufriendo politraumatismo. En la atención inicial refiere a dolor toracoabdominal y posteriormente deterioro neurológico. Evaluado por un neurocirujano y un cirujano general, se coloca un tubo torácico derecho y se realiza una laparoscopia y observándose poco sangrado de la cavidad abdominal. El paciente muestra deterioro de su estado general y muere por insuficiencia respiratoria. Durante el procedimiento de necropsia se determina hemorragia subaracnoidea y hernia cerebral, fracturas costales y consolidación neumónica, se observa un hematoma retroperitoneal masivo por rotura de quiste renal simple.

An innovative proposal for anophthalmic cavity reconstruction surgery with bone cement: a case report / Proposta inovadora para reconstrução de cavidades anoftálmicas utilizando cimento ósseo: um relato de caso

ABSTRACT We present a patient who underwent evisceration surgery after spontaneous rupture of the ocular globe due to long-data uncontrolled glaucoma, with posterior placement of an orbital implant made of a bone cement compound based on polymethylmethacrylate as alternative materials were not available. Such a compound is characterized by excellent biocompatibility and low cost, which makes it an interesting alternative for treatment. The anophthalmic socket was successfully filled, providing proper esthetic results and favorable conditions for the posterior scleral prosthesis implantation. No complications were observed during 10 months of follow-up. We believe that, in the absence of alternative materials, low-cost materials may be used in emergency settings to repair anophthalmic cavities and provide satisfactory functional and esthetic outcomes.

RESUMO Apresentamos um paciente que foi submetido à cirurgia de evisceração após ruptura espontânea do globo ocular devido a glaucoma não controlado de longa data, com posterior colocação de implante orbital feito de cimento ósseo, composto à base de polimetilmetacrilato, diante da indisponibilidade de materiais alternativos. Tal composto se caracteriza pela excelente biocompatibilidade e baixo custo, o que o torna uma alternativa interessante para o tratamento. A cavidade anoftálmica foi preenchida com sucesso, fornecendo resultados estéticos adequados e condições favoráveis para o implante posterior de prótese escleral. Nenhuma complicação foi observada durante os 10 meses de seguimento. Acredi­tamos que, na ausência de materiais alternativos, materiais de baixo custo podem ser usados em situações emergenciais para preencher cavidades anoftálmicas e prover resultados funcionais e estéticos satisfatórios.

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.

Síndrome de Boerhaave: uma complicação rara em pós-operatório de cirurgia estética / Boerhaave syndrome: a rare complication of cosmetic surgery

Introdução: Este estudo se trata de um relato de caso que tem por objetivo alertar os cirurgiões para uma possível complicação em pós-operatório de cirurgias estéticas longas sob anestesia geral. A Síndrome de Boerhaave é uma doença grave que ameaça a vida do paciente e merece um diagnóstico precoce até 12hs e um tratamento adequado. Relato de caso: A paciente no pós-operatório de cirurgia plástica abdominal e mastopexia apresentou, após anestesia geral, crises de vômito e náuseas. Resultados: Paciente com 58 anos do sexo feminino submetida à dermolipectomia abdominal e mastopexia pela a técnica de pedículo inferior sob raquianestesia, onde após um período de quatro horas do término da cirurgia apresentou vários episódios de vômitos. Após 10 horas do ato cirúrgico apresentou queixa de algia ao deglutir, seguida de algia intensa generalizada, dispneia intensa, sudorese, palidez, PA 90x50mmhg. Com a piora do quadro a paciente foi encaminhada para a unidade de terapia intensiva onde foi entubada. Foram realizados exames laboratoriais, toracocentese e exames radiológicos. Atualmente, a paciente encontra-se com prótese esofágica. Conclusões: Fazendo a correlação com a bibliografia, no caso em tela sugere-se evitar cirurgias prolongadas, principalmente sob anestesia geral onde pode ocorrer a retenção de gás carbônico, que pode levar a crise emética no pós-operatório em pacientes com antecedentes de doença esofagiana e estar atentos aos sintomas, não descartando a possibilidade da ocorrência da Síndrome Boerhaave.

Introduction: The objective of this case report is to alert surgeons to a possible postoperative complication of long cosmetic surgery under general anesthesia. Boerhaave syndrome is a serious life-threatening disease that requires diagnosis within 12 hours and proper treatment. Case report: A 58-year-old female patient presented with vomiting and nausea after abdominoplasty and mastopexy under general anesthesia. Results: The patient underwent dermolipectomy and mastopexy using the inferior pedicle technique under spinal anesthesia. Four hours after the operation, she presented several episodes of vomiting. Ten hours after the operation, she reported painful swallowing followed by generalized severe pain and presented severe dyspnea, sweating, pallor, and a 90/50 mmHg blood pressure. As the condition worsened, the patient was referred to the intensive care unit where she was intubated and underwent laboratory tests, thoracentesis, and radiological examinations. The patient currently uses an esophageal prosthesis. Conclusions: The literature suggests avoiding prolonged surgery, especially under general anesthesia, because of the risk of carbon dioxide retention, which may lead to postoperative emetic crisis in patients with a history of esophageal disease. It also suggests paying attention to symptoms, not excluding the possibility of Boerhaave syndrome.

Ruptura espontánea del semitendinoso secundario al uso de una quinolona / Spontaneous semitendinosus rupture secondary to the use of a quinolone

Resumen La ruptura espontánea de un tendón secundario al uso de una quinolona es un efecto adverso poco común, pero que con el paso de los años se ha venido documentado con mayor frecuencia. A pesar de lo anterior, aún no hay estudios clínicos que permitan aclarar su fisiopatología, qué estrategias pueden disminuir el riesgo de desarrollar una ruptura espontánea o a qué dosis de las diferentes quinolonas se aumenta el riesgo de presentar una ruptura espontánea. Adicionalmente, varías guías de práctica clínica incentivan el uso de las quinolonas como primera línea para el manejo de infecciones respiratorias o de vías urinarias sin hacer consideraciones sobre este efecto adverso. Por lo anterior, presentamos a continuación el caso de un paciente de 31 años que posterior al inicio de ciprofloxacina para el manejo de una diarrea aguda presento una ruptura espontánea del tendón del semitendinoso secundario al uso de la quinolona. (Acta Med Colomb 2019; 44: 115-118).

Abstract The spontaneous rupture of a tendon secondary to the use of a quinolone is an uncommon adverse effect, but over the years has been documented more frequently. Despite this, there are still no clini cal studies to clarify its pathophysiology, nor which strategies can reduce the risk of developing a spontaneous rupture or at what dose of the different quinolones the risk of presenting a spontaneous rupture increases. In addition, several clinical practice guidelines encourage the use of quinolones as the first line for the management of respiratory or urinary tract infections without considering this adverse effect. Therefore, the case of a 31 year old patient who after the start of ciprofloxacin for the management of acute diarrhea had spontaneous semitendinosus tendon rupture secondary to the use of quinolone, is presented.

Spontaneous heterotopic triplet pregnancy with a two viable intrauterine embryos and an ectopic one with right tubal rupture / Gravidez heterópica tripla espontânea com dois embriões intrauterinos viáveis e um ectópico com ruptura da tuba uterina direita

Abstract Heterotopic pregnancy (HP) is defined as the simultaneous development of an intra- and an extra uterine gestation. The occurrence of a spontaneous triplet HP is an exceptionally rare medical condition. We report the case of a young woman with spontaneous heterotopic triplets at 8weeks of gestation, with amisdiagnosis of topic twins and acute appendicitis. The ectopic tubal pregnancy was ruptured and a salpingectomy was performed by laparotomy. The intrauterine pregnancy progressed uneventfully. The two healthy babies were delivery by cesarean section at 36 ± 2 weeks of gestation. Heterotopic triplets with ruptured tubal ectopic pregnancy represent a special diagnostic and therapeutic challenge for the obstetrician. A high rate of clinical suspicion and timely treatment by laparotomy or laparoscopy can preserve the intrauterine gestation with a successful outcome of the pregnancy.

Resumo A gravidez heterotópica é definida como o desenvolvimento simultâneo de uma gestação intra- e extra-uterina. A ocorrência de gravidez tripla heterotópica espontânea é uma condição médica excepcionalmente rara. Relatamos o caso de uma jovem com gravidez tripla espontânea, às 8 semanas de gestação, com um diagnóstico errôneo de gêmeos tópicos e apendicite aguda. A gravidez tubária ectópica estava rota e uma salpingectomia foi realizada por laparotomia. A gravidez intrauterina progrediu sem intercorrências. Os bebês nasceramsaudáveis por cesariana realizada às 36 semanas de gestação.Agravidez de heterotópicos comectopia e rotura tubária é umdesafio diagnóstico e terapêutico.Umalto índice de suspeita e tratamento oportuno por laparotomia ou laparoscopia podem preservar a gestação intrauterina com um resultado bem sucedido da gravidez tópica.
