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.

Bleeding risk of small intracranial aneurysms in a population treated in a reference center / Risco de sangramento de aneurismas intracranianos pequenos em uma população tratada em um centro de referência

ABSTRACT Large multicenter studies have shown that small intracranial aneurysms are associated with a minimal risk of bleeding. Nevertheless, other large series have shown that most ruptured aneurysms are, in fact, the smaller ones. In the present study, we questioned whether small aneurysms are indeed not dangerous. Methods: We enrolled 290 patients with newly-diagnosed aneurysms at our institution over a six-year period (43.7% ruptured). We performed multivariate analyses addressing epidemiological issues, cardiovascular diseases, and three angiographic parameters (largest aneurysm diameter, neck diameter and diameter of the nutrition vessel). Risk estimates were calculated using a logistic regression model. Aneurysm size parameters were stratified according to receiver operating characteristic (ROC) curves. Finally, we calculated odds ratios for rupture based on the ROC analysis. Results: The mean largest diameter for the ruptured versus unruptured groups was 13.3 ± 1.7 mm versus 22.2 ± 2.2 mm (p < 0.001). Multivariate analysis revealed a positive correlation between rupture and arterial hypertension (p < 0.001) and an inverse correlation with all three angiographic measurements (all p < 0.01). Aneurysms from the anterior cerebral artery bled more often (p < 0.05). According to the ROC curves, at the largest diameter of 15 mm, the sensitivity and specificity to predict rupture were 83% and 36%, respectively. Based on this stratification, we calculated the chance of rupture for aneurysms smaller than 15 mm as 46%, which dropped to 25% for larger aneurysms. Conclusion: In the population studied at our institution, small aneurysms were more prone to bleeding. Therefore, the need for intervention for small aneurysms should not be overlooked.

RESUMO Grandes estudos multicêntricos demostram que aneurismas intracranianos pequenos são associados a risco de sangramento mínimo. Outras grandes séries têm evidenciado que aneurismas rotos são em sua maioria os pequenos. Neste estudo questionamos até que ponto os aneurismas pequenos não são perigosos. Métodos: Avaliamos 290 novos casos de aneurismas tratados em nossa instituição durante 6 anos (43,7% rotos). Realizamos análises multivariadas com aspectos epidemiológicos dos pacientes, doenças cardiovasculares e três parâmetros angiográficos: maior diâmetro, diâmetro do colo e diâmetro do vaso nutridor do aneurisma. Estimativas de risco foram calculadas utilizando-se modelo de regressão logística. Parâmetros do tamanho aneurismático foram estratificados de acordo com curvas ROC. Também calculamos a razão de chances (odds ratios) de ruptura baseadas nas análises das curvas ROC. Resultados: O maior diâmetro médio para os grupos de aneurismas rotos e não-rotos foi 13.3 ± 1.7mm e 22.2 ± 2.2 (p < 0.001). Análises multivariadas revelaram uma correlação positiva entre ruptura aneurismática e hipertensão arterial (p < 0.001) e uma correlação inversa entre ruptura e as três medidas angiográficas (p < 0.01). Aneurismas da artéria cerebral anterior foram os que mais sangraram (p < 0.05). Análises das curvas ROC demonstram que no maior diâmetro de 15mm, a sensibilidade e especificidade para se predizer ruptura são de 83% e 36%. Baseando-se nessas estratificações, calculamos uma chance de ruptura para aneurismas menores de 15mm de 46% e de 25% para aneurismas maiores. Conclusão: Na população estudada, aneurismas pequenos são mais propensos a romper. Desta forma, a necessidade de intervenção para aneurismas pequenos não deve ser relevada.

Spontaneous rupture of right gastroepiploic artery aneurysm: a rare cause of hemorrhagic shock. case report

ABSTRACT CONTEXT: Aneurysms of the gastroepiploic arteries are seen only rarely. They are usually diagnosed during autopsy or laparotomy in patients with hemodynamic instability. Although the operation to treat this condition is relatively easy, delay in making the diagnosis affects the course of the disease. Case Report: A 57-year-old woman was admitted to the emergency department with abdominal pain and unconsciousness. A computed tomography scan showed extravasation of contrast agent at the headcorpus junction of the pancreas, and the patient underwent exploratory laparotomy under general anesthesia. During laparotomy, aneurysmatic rupture of the right gastroepiploic artery was detected. Control over bleeding was achieved by ligating the right gastroepiploic artery at its origin. The aneurysm was also resected and sent for pathological examination. CONCLUSION: Especially in cases of unidentified shock, splanchnic artery aneurysms should be kept in mind. Moreover, in the light of the data in the literature, the possibility of death should be taken into account seriously and, if feasible, prophylactic aneurysmectomy should be performed.

Performance of language tasks in patients with ruptured aneurysm of the left hemisphere worses in the post-surgical evaluation / Avaliação da linguagem em pacientes com hemorragia subaracnóidea aneurismática no hemisfério esquerdo piora após a cirurgia

ABSTRACT Sub-arachnoid hemorrhage (SAH) promotes impairment of upper cortical functions. However, few information is available emphasizing changes in language after aneurismal SAH and aneurysm location influence. Objective To assess the language and verbal fluency performance in aneurismal SAH pre- and post-surgery in patients caused by an aneurysm of the anterior communicating artery (AcomA), left middle cerebral artery (L-MCA) and left posterior comunicating artery (L-PcomA). Methods Assessment in 79 patients with SAH, on two occasions: pre- and post surgical treatment. They were divided into three groups by the aneurysms’ location. Results Deterioration is detected in the performance of all patients during the post-surgical period; L-MCA aneurysm patients displayed a reduction in verbal naming and fluency; L-PcomA patients deteriorated in the written language and fluency tasks. Conclusion After the surgical procedure the patients decreased in various language tasks and these differences in performance being directly related to the location of the aneurysm.

RESUMO Hemorragia subaracnóidea (HSA) proporciona alterações nas altas funções cerebrais. Contudo, há poucos trabalhos enfatizando as alterações da linguagem na HSA aneurismática e a influência da localização do aneurisma. Objetivos Analisar e comparar os desempenhos da linguagem e fluência verbal na HSA nos períodos pré e pós-cirúrgicos nos pacientes com aneurismas da comunicante anterior (AcomA), cerebral média (ACME) e comunicante posterior esquerdas (AcomPE). Métodos A avaliação da linguagem de 79 pacientes com HSA aneurismática foi realizada em duas ocasiões: pré e pós cirurgia. Eles foram divididos em três grupos de acordo com a localização do aneurisma. Resultados Os grupos apresentaram deterioração na avaliação pós-operatória com diferentes características. O grupo da ACME demonstraram deterioração na fluência e nomeação, enquanto o da AcomPE pioraram nos testes de linguagem escrita e fluência. Conclusões Após o tratamento cirúrgico, os pacientes deterioraram em vários itens de linguagem com diferenças relacionadas à localização do aneurisma.

ABSTRACT Purpose: To systematically review the methods for evaluation of smell in aneurysmal subarachnoid hemorrhage victims and to identify the changes found with the use of these methods. Research strategy: The literature search was performed in PubMed search platform and in the databases Web of Science, Scopus, PsycINFO, CINAHL, and ScienceDirect in August and September 2014. Selection criteria: Original articles published in any language, which addressed smell changes in aneurysmal subarachnoid hemorrhage and addressed to evaluate this function through specific methods were included. Review studies, case studies, book chapters, editorial, and studies that address the nonaneurysmal subarachnoid hemorrhage were excluded. Data analysis: The following variables were considered in data analysis: author/year, country, sample/age, treatment, method, the moment of smell evaluation, and results. Results: The search for articles resulted in 1,763 articles, of which, 9 original articles were selected for this review. It was observed that all articles were from European and Asian countries. Standardized and nonstandardized tests and questionnaires were used in olfactory assessment, and the goals ranged from assessing the smell before and/or after surgery in this population. Conclusion: Heterogeneity was observed in the methods used to evaluate the smell in aneurysmal subarachnoid hemorrhage and in the methods selected for application of evaluations. In addition, studies have demonstrated the existence of olfactory deficits in patients and the relationship between surgery and olfactory dysfunction.

Síndrome del desfiladero torácico neurogénico causado por la arteria escapular descendente: comunicación de un caso / Neurogenic thoracic gland syndrome caused by the descending descending artery: case report

El síndrome del desfiladero torácico es una entidad clínica compleja que abarca varias situaciones donde hay compresión del paquete vásculo-nervioso que suministra las extremidades superiores en el canal cervicotorácico. El síndrome se puede dividir en neurogénico y vascular de acuerdo con la estructura comprometida, siendo la primera la más frecuente. Entre las causas descritas están las costillas cervicales, anomalías de la primera costilla, músculos anómalos o hipertrofiados, traumatismos y tumores de la región. Describimos el caso de una paciente de 47 años que presenta un cuadro de cervicobraquialgia asociado con parestesias y paresia en la mano izquierda compatible con síndrome del desfiladero torácico en que la causa de la compresión era la arteria escapular descendente. Fue realizada una revisión de la literatura siendo encontrado sólo un caso similar.

The thoracic outlet syndrome is a complex clinical entity that encompasses several situations where there is compression of the neurovascular bundle that supplies the upper limbs in the cervicothoracic channel. It can be divided in neurogenic and vascular according to the structure committed, the first being the most frequently found. Among the causes described there are cervical ribs, anomalies of the first rib, anomalous or hypertrophied muscles, trauma and tumors of the region. We report the case of a 47 year old patient who presents with a clinical picture of cervicobrachialgia associated with paresthesia and paresis on the left hand compatible with thoracic outlet syndrome in which the cause of compression was the descending scapular artery.We conducted a literature review and found only one similar case.

Endoscopic ultrasound hemostasis techniques / Técnicas de hemostasia por ultrasonido endoscópico

Since its development, endoscopic ultrasound (EUS) has evolved from a simple diagnostic technique to an important therapeutic tool for interventional endoscopy. EUS analysis provides real-time imaging of most major thoracic and abdominal vessels, and the possibility to use needle puncture with a curved linear array echoendoscope as a vascular intervention. In this review, we describe the endoscopic ultrasound approach to vascular therapy outside of the gastrointestinal wall.

Desde su introducción, la ultrasonografía endoscópica (USE) evolucionó de una técnica diagnóstica a un procedimiento terapéutico. La USE proporciona una imagen en tiempo real de la mayoría de los grandes vasos torácicos y abdominales, brindando la posibilidad de utilizar la aguja de punción a través del ecoendoscopio como una intervención vascular. En esta revisión, describimos la intervención vascular por fuera de la pared gastrointestinal mediante ecoendoscopia.

Forensic appraisal of subarachnoid hemorrhage / 法医学杂志

Subarachnoid hemorrhage (SAH) can be classified as traumatic SAH or spontaneous SAH based on etiology. The traumatic SAH is the common manifestation of head injury and difficult to make a diagnosis in forensic investigation. Based on practical experiences of forensic investigation and relevant references, the main points (SAH identification, examination, death mechanism) were summarized in this article. For the understanding, we try to classify the traumatic SAH into three subtypes: brain injury associated SAH, traumatic rupture of basal cerebral vessels SAH and traumatic focal SAH.

Aneurisma de artéria femoral superficial roto: relato de caso e revisão de literatura / Ruptured superficial femoral artery aneurysm: case report and literature review

O aneurisma de artéria femoral superficial é um evento raro que costuma manifestar-se em pacientes com idade avançada, frequentemente associado a outros aneurismas, periféricos ou de aorta abdominal. O caso relatado refere-se a um paciente cujo aneurisma de artéria femoral superficial se apresentou roto e associado a um aneurisma de aorta abdominal. Foi submetido à revascularização cirúrgica fêmoro-poplítea mediante prótese de politetrafluoretileno, com sucesso. A revisão da literatura demonstra que embora haja uma tendência à manifestação aguda da doença, principalmente como ruptura, os resultados com o tratamento cirúrgico são excelentes.

Superficial femoral artery aneurysm is rare and usually occurs in elderly patients, often associated with peripheral or abdominal aortic aneurysms. In the reported case, the patient presented with a ruptured superficial femoral artery aneurysm associated with an abdominal aortic aneurysm. A successful femoropopliteal bypass was performed using a polytetrafluorethylene graft. Literature review shows that, despite the tendency for acute onset of the aneurysm, primarily with a rupture, surgical results are excellent.

Aneurisma de artéria ilíaca interna roto: relato de caso / Ruptured internal iliac artery aneurysm: case report

Aneurismas isolados da artéria ilíaca interna são raros, acometem 0,1 por cento da população e correspondem a 1 por cento dos aneurismas aorto-ilíacos. Na maioria das vezes, os pacientes são assintomáticos, mas podem apresentar dor abdominal, massa pulsátil no hipogástrio ou na fossa ilíaca, sintomas compressivos urinários, gastrointestinais ou neurológicos. Podem ocasionar quadro de abdome agudo, principalmente quando há ruptura. O diagnóstico precoce dos aneurismas isolados de artéria ilíaca interna é incomum, sendo identificados quando mais volumosos ou rotos, o que aumenta significativamente sua morbimortalidade e torna seu prognóstico mais reservado. Dessa forma, representam um desafio terapêutico. A ligadura cirúrgica tem sido o tratamento mais comum, entretanto a cirurgia endovascular tem mostrado bons resultados, inclusive nos aneurismas rotos. É relatado caso de aneurisma de artéria ilíaca interna isolado roto diagnosticado durante laparotomia para abordagem de abdome agudo.

Isolated internal iliac artery aneurysms are rare. They affect 0.1 percent of the population, and account for 1 percent of aortoiliac aneurysms. Patients are mostly asymptomatic, yet they can have abdominal pain, pulsatile mass in the hypogastrium or iliac fossa, or urinary, gastrointestinal or neurological compressive symptoms. Such aneurysms are likely to course with an acute abdomen, especially when ruptured. Early diagnosis of isolated internal iliac artery aneurysms is difficult, as they are more easily detected when larger or ruptured, which significantly raises their morbidity and mortality rate and determines a poor prognosis. Therefore, they are a therapeutic challenge. Surgical ligation has been the most common treatment; however, the endovascular approach has presented good outcomes, even in the event of ruptured aneurysms. A case of ruptured isolated iliac artery aneurysm diagnosed during a laparotomy (acute abdomen approach) is reported.

Early surgery for ruptured cerebral aneurysms: technical note

We describe a collection of techniques to be considered in the early clipping of ruptured cerebral aneurysms located in the anterior circulation when dealing with the swollen red and scaring brain many times found after craniotomy.

Descrevemos uma coleção de técnicas a serem consideradas na clipagem precoce dos aneurismas cerebrais rotos localizados na circulação anterior quando lidando com o cérebro vermelho inchado e assustador encontrado muitas vezes após a craniotomia.

Aneurisma ilíaco associado a fístula arteriovenosa / Iliac aneurysm associated with arteriovenous fistula / Iliac aneurysm associated with arteriovenous fistula

A ruptura dos aneurismas aorto-ilíacos para a veia ilíaca ou veia cava é uma complicação pouco comum. A hipertensão venosa leva a vários sinais e sintomas, o que dificulta o diagnóstico pré-operatório, tais como edema do membro inferior, dispnéia, hematúria, sinais de insuficiência renal ou cardíaca. Sopro abdominal é a chave do diagnóstico clínico, associado à massa pulsátil e dor abdominal. O reconhecimento da fístula arteriovenosa no pré-operatório é importante para o planejamento cirúrgico. Relatamos um caso de aneurisma da artéria ilíaca comum e interna direita associado a fístula para veia ilíaca comum, cursando, inicialmente, com edema do membro inferior direito e dispnéia, o que levou ao diagnóstico incorreto de trombose venosa profunda.

Rupture of aortoiliac aneurysms into the iliac vein or vena cava is an uncommon complication. Many signs and symptoms develop as a result of venous hypertension, which makes preoperative diagnosis difficult, such as leg edema, dyspnea, hematuria, signs of renal or cardiac insufficiency. Abdominal bruit, associated with pulsatile mass and abdominal pain, is the key for clinical diagnosis. Preoperative recognition of arteriovenous fistula is important for surgical planning. We report a case of right internal and common iliac artery aneurysm associated with fistula into the common iliac vein. Initial symptoms were right leg edema and dyspnea, which induced to the incorrect diagnosis of deep vein thrombosis.

Subretinal neovascularization following ruptured retinal arterial macroaneurysm: case report

A 51-year-old black woman was referred to our Retina Clinic for evaluation of loss of vision in her left eye. She was previously diagnosed with a ruptured retinal arterial macroaneurism (RAM) in the same eye. The ophthalmoscopic examination of the affected eye disclosed a subretinal lesion with some hemorrhage and exudation in the same area previously diagnosed with ruptured RAM. Fluorescein angiography revealed a gradually hyperfluorescent net of vessels located in the subfoveal region, consistent with the diagnosis of subretinal neovascular membrane. In this paper we stress the possibility of subretinal neovascularization following a ruptured RAM, even as a rare event.

Paciente de 51 anos foi encaminhada ao Setor de Retina para avaliação de perda visual no olho esquerdo. A paciente apresentava o diagnóstico prévio de macroaneurisma arterial retiniano (MAR) rôto no referido olho. O exame oftalmológico revelou lesão sub-retiniana hemorrágica associada à exsudação na área previamente diagnosticada com MAR. A angiofluoresceinografia revelou hiperfluorescência gradual localizada na região subfoveal, consistente com o diagnóstico de membrana neovascular sub-retiniana (MNSR). Nosso artigo aponta para a possibilidade, embora rara, da formação de uma MNSR após MAR rôto.

Massive Gastrointestinal Bleeding due to Aneurysmal Rupture of Ileo-colic Artery in a Patient with Behcet's Disease / 대한소화기학회지

Behcet's disease has been recognized as a systemic vasculitis characterized by the involvement of multiple organs such as orogenital ulcers, eye lesions including uveitis and optic neuritis, and skin lesions including folliculitis and erythema nodosum. Vascular involvement occurs occasionally and is classified into thrombosis and aneurysm. However, massive gastrointestinal bleeding from arterial aneurysm is a rare manifestation of intestinal Behcet's disease. Recently, we experienced a case of intestinal Behcet's disease presenting with massive gastrointestinal bleeding due to aneurysmal rupture of ileo-colic artery. A 30-year-old male with Behcet's disease was admitted because of massive gastrointestinal bleeding. A large ileo-cecal ulcer was revealed as a bleeding focus on colonoscopic examination. Celiac angiography showed aneurysm and stenosis of ileo-colic artery. After the failure of hemostasis with arterial embolization, ileocecectomy was performed. After the resection hematochezia was completely stopped.
