Rotura aneurismática de la arteria hepática común / Ruptured common hepatic artery aneurysm

RESUMEN Los aneurismas de la arteria hepática son una patología poco frecuente. Cuando son sintomáticos, se debe sospechar un sufrimiento aneurismático y su tratamiento está indicado. Presentamos el caso clínico de un paciente con mal terreno cardiovascular, que consultó por un cuadro clínico de dolor epigástrico, repercusión hemodinámica e ictericia. La imagenología evidenció la presencia de un aneurisma de la arteria hepática común complicado con compromiso del origen de la arteria hepática propia y la arteria gastroduodenal. La presencia de una vascularización arterial hepática "no convencional" con una arteria hepática derecha proveniente de la arteria mesentérica superior, en la angiotomografía, permitió cambiar la táctica quirúrgica haciéndose prescindible la realización de un bypass. Este caso resalta la importancia de determinar en el preoperatorio no solo la extensión del aneurisma, sino también la anatomía vascular hepática a fin de planificar mejor la cirugía, disminuyendo así la morbimortalidad de esta enfermedad.

ABSTRACT Hepatic artery aneurysms are rare. Expanding aneurysms should be suspected in case of symptoms and treatment is indicated. We report the case of a patient with a history of cardiovascular disease who sought medical care due to epigastric pain, hemodynamic instability and jaundice. The imaging tests showed the presence of an aneurysm of the common hepatic artery complicated with involvement of the origin of the proper hepatic artery and the gastroduodenal artery. The surgical approach could be changed due to presence of a "non-conventional" hepatic arterial variant with a right hepatic artery originating from the superior mesenteric artery in the computed tomography angiography as bypass surgery was not necessary. This case highlights the importance of determining the extent of the aneurysm in the preoperative period and the anatomy of the hepatic vessels to better plan the surgery, thus reducing morbidity and mortality of this disease.

Microsurgery versus embolization: different risk factors for short- and long- term outcomes of patients with ruptured aneurysms

Purpose: To evaluate the risk factors for poor outcomes after surgical and endovascular treatment of aneurysmal subarachnoid hemorrhage (aSAH). Methods: Patients with ≥ 18-years of age and aSAH were included, while patients who died within 12 h of admission or lost follow-up were excluded. All participants underwent standardized clinical and radiological assessment on admission and were reassessed at discharge and at 6-months follow-up using the Glasgow Outcome Scale (GOS). Results: Death at discharge was associated with female gender, anterior communication artery (ACoA) aneurysm location and presence of atherosclerotic plaque in the surgical group, and with age in the endovascular group. Both groups had clinical condition on follow-up associated with mFisher score on admission and hypertension. GOS on follow-up was also associated with presence of atherosclerotic plaque and multiple aneurysms in surgical group, and with age in endovascular group. Conclusions: Subjects treated surgically are prone to unfavorable outcomes if atherosclerotic plaques and multiple aneurysms are present. In patients with endovascular treatment, age was the main predictor of clinical outcome.

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.

Pure arterial malformation with associated aneurysmal subarachnoid hemorrhage: Two case reports and literature review / 中南大学学报(医学版)

In recent years, in the absence of venous component, dilated, overlapping, and tortuous arteries forming a mass of arterial loops with a coil-like appearance have been defined as pure arterial malformation (PAM). It is extremely rare, and its etiology and treatment have not yet been fully elucidated. Here, we reported 2 cases of PAM with associated aneurysmal subarachnoid hemorrhage in this paper. Both patients had severe headache as the first symptom. Subarachnoid hemorrhage was found by CT and computed tomography angiography (CTA) and PAM with associated aneurysm was found by digital subtraction angiography (DSA). In view of the distribution of blood and the location of aneurysms, the aneurysm rupture was the most likely to be considered. Based on the involvement of the lesion in the distal blood supply, only the aneurysm was clamped during the operation. It used to be consider that PAM is safety, because of the presentation and natural history of previously reported cases. Through the cases we reported, we have doubted about "the benign natural history" and discussed its treatment. PAM can promote the formation of aneurysms and should be reviewed regularly. The surgical indications for PAM patients with aneurysm formation need to be further clarified. Management of PAM patients with ruptured aneurysm is the same as that of ruptured aneurysm. Whether there are indications needed to treat simple arterial malformations remains to be further elucidated with the multicenter, randomized controlled studies on this disease.

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.

Anterior Communicating Artery Aneurysm Uncommon Hemorrhagic Presentation: Case Report

Intracranial aneurysm rupture causes subarachnoid hemorrhage in 80% of the cases, and it may be associated with intracerebral hemorrhage and/or intraventricular hemorrhage (IVH) in 34% and 17% of the patients, respectively. However, on rare occasions, aneurysm rupturemay be present causing isolate intracerebral hemorrhage or IVH without subarachnoid hemorrhage. We describe an unusual case of an anterior communicating aneurysm rupture presented with IVH, without subarachnoid hemorrhage. Although isolated IVH is rare, aneurysm rupture is a possible condition. Patients presenting with head computed tomography revealing IVH without subarachnoid hemorrhage should be promptly investigated with contrasted image exam to identify and treat possible causes, even in the absence of subarachnoid hemorrhage.

Residual lesions in patients undergoing microsurgical clipping of cerebral aneurysms in a reference university hospital

OBJECTIVES: This study aimed to analyze the incidence and epidemiological, angiographic, and surgical aspects associated with incomplete clipping of brain aneurysms in a cohort of patients undergoing microsurgical treatment. METHODS: The medical record data of patients who underwent microsurgery for cerebral aneurysm treatment and postoperative digital subtraction angiography, treated at the same teaching hospital between 2014 and 2019, were retrospectively analyzed. The studied variables involved epidemiological and clinical data, as well as neurological status and findings on neuroimaging. The time elapsed between hemorrhage and microsurgical treatment, data on the neurosurgical procedure employed for aneurysm occlusion, and factors associated with the treated aneurysm, specifically location and size, were also evaluated. RESULTS: One hundred and seventeen patients were submitted to 139 neurosurgical procedures, in which 167 aneurysms were clipped. The overall rate of residual injury was 23%. Smoking (odds ratio [OR]: 3.38, 95% confidence interval [CI95%]: 1.372-8.300, p=0.008), lesion size >10 mm (OR: 5.136, CI95%: 2.240-11.779, p<0.001) and surgery duration >6 h (OR: 8.667, CI95%: 2.713-27.681, p<0.001) were found to significantly impact incomplete aneurysm occlusion in the univariate analyses. CONCLUSION: Incomplete microsurgical aneurysm occlusion is associated with aneurysm size, complexity, and current smoking status. Currently, there is no consensus on postoperative assessment of clipped aneurysms, hindering the correct assessment of treatment outcomes.

Rotura de aneurisma de artéria poplítea em paciente clinicamente diagnosticado com síndrome de Marfan / Ruptured popliteal artery aneurysm in a patient with a clinical diagnosis of Marfan syndrome

Resumo A artéria poplítea é o principal local para a ocorrência de aneurismas periféricos. Suas formas de apresentação agudas são potencialmente ameaçadoras à viabilidade do membro e à vida, dentre as quais destacamos a sua rotura. Apesar de ser um evento raro, sua rotura demanda rápida proposta de intervenção para satisfatório desfecho terapêutico. O tratamento padrão-ouro é o cirúrgico convencional e se dá pela interposição de veia safena magna. Trabalhos feitos nas últimas décadas vêm encontrando associações entre a síndrome de Marfan e aneurismas periféricos. Este relato apresenta um caso de um aneurisma de artéria poplítea esquerda roto tratado com sucesso em um paciente de 82 anos diagnosticado clinicamente como portador de síndrome de Marfan previamente desconhecida.

Abstract The popliteal artery is the main site of occurrence of peripheral aneurysms. Acute presentations constitute a potential threat to limb viability and to life, especially in the event of rupture. Rupture is a rare event, but one that demands an immediate intervention decision to achieve a satisfactory treatment outcome. The gold standard treatment is conventional surgery, effecting repair by interposition of a great saphenous vein graft. Studies conducted in recent decades have found associations between Marfan Syndrome and peripheral aneurysms. This report presents a case of a ruptured left popliteal artery aneurysm successfully treated in an 82-year-old patient clinically diagnosed with previously unknown Marfan syndrome.

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.

Vitreous Hemorrhage after Aneurismal Rupture: Terson Syndrome

Introduction Terson syndrome is described as an intraocular hemorrhage consequent to a spontaneous subarachnoid hemorrhage (SSAH). In the present article, we describe cases of patients who underwent neurosurgical treatment of ruptured cerebral aneurysmat our institution over a period of one year, and who were diagnosed with Terson syndrome. Methods The present study included patients with a diagnosis of SSAH by rupture of a cerebral aneurysm who underwent treatment in our neurosurgical service from December 2009 to December 2010. The patients were followed-up for a minimum of 20 months.We have also performed a literature review and compared the data with those available in the current literature. Results The present study included 34 patients, 18 (53%) of which underwent endovascular treatment, and 16 (47%) who underwent microsurgical clipping. In the sample, the mortality was 14.7% (5 patients), the same percentage of patients who were diagnosed with Terson Syndrome, which is an incidence of 14.7%. Regarding the ophthalmologic evaluation, all patients had vitreous hemorrhage detected by an ultrasound examination, which was unilateral in only two patients. Visual acuity improved in all patients, being incomplete in only one of them. Conclusion Terson syndrome is relatively common and is associated with higher mortality. With the existence of an effective treatment, it should be investigated in all patients with SSAH.

Ruptured Bilateral Pericallosal Artery Aneurysm in Mirror Position: Case Report

Introduction Pericallosal artery (PA) aneurysms represent 2 to 9% of all intracranial aneurysms, and their management remains difficult. Objective The aim of the present study is to describe the case of an adult woman with subarachnoid hemorrhage and bilateral PA aneurysm in mirror position. Case Report A 46-year-old woman was referred to our institution 20 days after a sudden severe headache. She informed that she was treating her arterial hypertension irregularly, and consumed 20 cigarettes/day. The patient was neurologically intact at admission. A non-contrast computed tomography (CT) on the first day of the onset of the symptoms revealed hydrocephaly and subarachnoid hemorrhage (Fisher III). An angio-CT/digital subtraction arteriography showed bilateral PA aneurysms in mirror position. The patient was successfully treated with surgery via the right interhemispheric approach (because the surgeon is right-handed); the surgeon performed the proximal control with temporary clipping, and introduced an external ventricular drain at the end of the surgery. The patient was discharged on the fourth postoperative day without any additional neurological deficits or ventricular shunts. Conclusion Ruptured PA aneurysm is a surgically challenging aneurysm due to the many anatomical nuances and risk of rebleeding. However, the operativemanagement of ruptured bilateral PA aneurysms is feasible and effective.

Aneurisma isolado de artéria femoral superficial roto contido: relato de caso / Isolated ruptured aneurysm of the superficial femoral artery: case report

Aneurismas verdadeiros isolados da artéria femoral superficial (AFS) são eventos raros. Manifestam-se principalmente em homens idosos e frequentemente estão associados a outros aneurismas. Possuem etiologia variada e costumam ser detectados quando apresentam complicações como trombose, embolização distal ou, mais raramente, ruptura. O presente caso refere-se a um paciente cujo aneurisma de AFS se apresentou roto contido e sem associações com outros aneurismas. Foram realizados eco-Doppler colorido arterial, que diagnosticou a ruptura, e angiotomografia, que evidenciou aneurisma sacular de AFS medindo 11,4 × 8,8 cm, com grande trombo mural. Uma arteriografia foi utilizada para programação de revascularização, e detectou-se leito distal via artéria tibial anterior. O paciente foi submetido a revascularização cirúrgica convencional eletiva em artéria femoropoplítea distal com veia safena ipsilateral invertida, com sucesso. Apresentou como complicação pós-operatória infecção de sítio cirúrgico. A pesquisa microbiológica teve resultado negativo, e o estudo anatomopatológico confirmou aneurisma verdadeiro da AFS

Isolated true aneurysms of the superficial femoral artery (SFA) are rare events. They mostly manifest in elderly men and are frequently seen in conjunction with other aneurysms. They have varied etiology and are usually detected when they complicate with thrombosis or distal embolization, or, more rarely, when they rupture. The present case report describes a patient with an aneurysm of the SFA that was ruptured and contained and who had no other aneurysms. Color Doppler ultrasound of the arteries revealed the rupture and angiotomography showed a saccular aneurysm of the SFA measuring 11.4 × 8.8 cm, with a large mural thrombus. Arteriography was used to plan revascularization and showed the distal bed with outflow via the anterior tibial artery. The patient was treated with conventional elective distal femoropopliteal surgical revascularization with the ipsilateral saphenous vein inverted, which was successful. Recovery was complicated by a postoperative surgical site infection. Microbiology tests were negative and the anatomopathological study confirmed a true aneurysm of the SFA

Aneurismas paraclinoideos: experiencia personal de 1 año en el Hospital Regional de Temuco / Paraclinoid aneurysm: 1 year personal experience at Hospital Regional de Temuco

Se presenta la experiencia personal en el tratamiento de 5 pacientes con 7 aneurismas paraclinoideos tratados quirúrgicamente en el Hospital Regional Temuco durante junio de 2015 y julio de 2016 (13 meses). Todos los pacientes fueron previamente discutidos con neurorradiologo Intervencional local y considerados no favorables para terapia endovascular. En todos ellos se realizó una craneotomía mini pterional con clinoidectomía extradural y exposición de la arteria carótida interna cervical. Cuatro pacientes consultaron con hemorragia subaracnoidea y requirieron cirugía cerebral de urgencia. En 6 aneurismas se realizó clipaje y en 1 trapping. Cuatro pacientes no tuvieron deterioro neurológico y evolucionaron favorablemente mientras que 1 paciente falleció por hipoperfusión secundario al trapping de la carótida supraclinoidea. Se enfatiza el manejo interdisciplinario, el plan preoperatorio y el conocimiento de la neuroanatomía en el tratamiento de esta patología.

A personal experience is presented in treating 5 patients with 7 paraclinoid aneurysm who underwent surgery at Hospital Regional Temuco between june 2015 and july 2016 (13 months). All patients were previously discussed with local interventional neuroradiologist considering them not favorable to endovascular therapy. Mini pterional craniotomy with extradural clinoidectomy and internal cervical carotid artery exposure was performed in all of them. 4 patients presented with subarachnoid hemorrhage and required urgent brain surgery. Direct clipping was optimal in 6 aneurysm and 1 was treated with trapping. 4 patients had no neurological deteriotation with excellent outcome and 1 patient died because of hypoperfusion secondary to the supraclinoid carotid trapping. Interdisciplinary management, preoperative planning and neuroanatomy knowledge are emphasized in order to treat this pathology.

Middle cerebral artery aneurysms: aneurysm angiographic morphology and its relation to pre-operative and intra-operative rupture / Aneurismas da artéria cerebral média: morfologia angiográfica dos aneurismas e sua relação com ruptura pré-operatória e intra-operatória

ABSTRACT Objective Correlate the middle cerebral artery bifurcation aneurysm morphology with the pre-operative and intra-operative risk of rupture. Methods Forty patients with 46 middle cerebral artery bifurcation aneurysms were treated microsurgically by the same surgeon. Aneurysms were classified according to shape and the Fisher test was applied to analyze the effect of morphology on the pre-operative and intra-operative rupture. Results Pre-operative and intra-operative ruptures were observed in 8/46 patients (17.4%) and 14/46 patients (30.4%) respectively. Thirty-two cases (69.6%) had no symptoms postoperatively, modified Rankin score (MRS) of 0; 6.5% had MRS of 1 (no significant disability); 13% had MRS of 2 (slight disability); 4.3% had moderately severe disability (MRS of 4); and there were 3 deaths (6.5%) post-operatively. The morphology was not directly related to the rupture rate. Conclusion In general, ruptures are not affected by the morphology or the studied variables. Larger series are needed to validate these outcomes.

RESUMO Objetivo Correlacionar a morfologia do aneurisma da bifurcação da artéria cerebral média com o risco de ruptura pré-operatória e intra-operatória. Métodos 40 pacientes com 46 aneurismas de bifurcação da artéria cerebral média receberam tratamento microcirúrgico pelo mesmo cirurgião. Os aneurismas foram classificados de acordo com a morfologia e o teste de Fisher foi aplicado para analisar o efeito da morfologia sobre a ruptura pré-operatória e intra-operatória. Resultados As rupturas pré e intra-operatória foram observadas em 8/46 pacientes (17,4%) e 14/46 (30,4%) respectivamente. Trinta e dois casos (69,6%) não apresentaram sintomas pós-operatórios, pontuação de Rankin modificada (MRS) de 0, 6,5% tinham MRS de 1 (sem incapacidade significativa), 13% tinham MRS de 2 (leve incapacidade), 4,3% moderadamente grave (MRS de 4) e houve 3 óbitos (6,5%) durante o pós-operatório. A morfologia não estava diretamente relacionada à taxa de ruptura pré-operatória ou intra-operatória. Conclusão Em geral, as rupturas não são afetadas pela morfologia ou pelas variáveis estudadas. São necessárias séries maiores para validar esses resultados.

Reparo de aneurisma de artéria ilíaca roto em criança / Repair of ruptured iliac artery aneurysm in a child

Resumo Relatamos o caso de uma menina de 12 anos que deu entrada na unidade de emergência com quadro de abdome agudo hemorrágico, massa abdominal pulsátil e instabilidade hemodinâmica. Confirmado o diagnóstico de aneurisma roto de artéria ilíaca direita, foi realizada correção cirúrgica de emergência por reparo aberto com reconstrução extra-anatômica, utilizando enxerto sintético de fino calibre, compatível com a anatomia. O tratamento foi bem-sucedido e a criança apresentou evolução favorável em curto prazo.

Abstract We describe the case of a 12-year-old girl who presented at the emergency department with hemorrhagic acute abdomen, an abdominal pulsating mass and hemodynamic instability. A diagnosis of ruptured right iliac artery aneurysm was confirmed and an emergency open repair procedure was performed with extra-anatomic reconstruction, using a small-caliber synthetic graft, compatible with her anatomy. The treatment was successful and the child was doing well at short-term follow-up.

Surgical Management of Ruptured Posterior Circulation Aneurysms ­ A Single Center Experience

Objective The treatment of ruptured aneurysms of the posterior circulation is a controversy in neurosurgery. The aim of this work is to describe the experience and results of the early surgical treatment of this pathology at Centro Hospitalar do Porto. Method We retrospectively analyzed the medical records of all patients aged over 18 who, in the period between 1999­2013, were admitted to our center with the diagnosis of ruptured saccular posterior circulation aneurysm. The patients were clinically staged at admission using the Hunt & Hess (H&H) scale. The modified Glasgow Outcome Scale (mGOS) was used to assess the outcome at discharge and after 6 months. Results Between 1999­2013, 59 patients underwent surgery for ruptured posterior circulation aneurysms. Eighty percent of the patients were female, and their average age was 58.7 years. Posterior-inferior cerebellar artery aneurysms accounted for 49.2% of surgeries, while basilar aneurysms accounted for 28.8%. Upon admission, 86.4% of patients were classified as H&H1­3, and 13.6% as H&H4­5. The outcomes at discharge and at 6 months were as follows: at discharge, mGOS1 in 5.1%, mGOS2­3 in 18.6%, and mGOS4­5 in 76.3%; at 6 months, mGOS1 in 10.2%, mGOS2­3 in 10.2%, and mGOS4­5 in 79.6%. There was a statistically significant correlation between basilar aneurysms and worse outcomes (p » 0.011). No correlation was found between the values of the H&H scale upon admission and outcome. Conclusions The functional outcome of our group of patients is mainly in line with what is described in other series from the literature. However, there is a trend toward lower mortality but higher morbidity rates.

Objetivo O tratamento dos aneurismas rotos da circulação posterior é uma controvérsia neurocirúrgica. Pretende-se com este trabalho relatar a experiência e os resultados do tratamento cirúrgico precoce desta patologia no Centro Hospitalar do Porto. Métodos Foram analisados retrospectivamente os processos clínicos dos pacientes com idade > 18 anos que, no período entre 1999­2013, foram admitidos no nosso centro com o diagnóstico de aneurisma sacular roto da circulação posterior. Utilizou-se a escala de Hunt & Hess (H&H) para aferir a gravidade clínica dos pacientes, e a Escala de Outcome de Glagow modificada (mGOS) para aferir o outcome dos pacientes à data da alta e aos 6 meses. Resultados Entre 1999­2013, foram operados 59 pacientes com aneurismas rotos da circulação posterior. Oitenta por centro dos pacientes eram do sexo feminino, com uma média de idade média de 58.7 anos. Aneurismas da artéria cerebelosa posteroinferior foram responsáveis por 49,2% das cirurgias, ao passo que os da artéria basilar, por 28,8%. À admissão, 86,4% dos pacientes eram H&H1­3, e 13,6%, H&H4­5. O outcome à data da alta e aos 6 meses foi o seguinte: à data de alta, mGOS1 em 5,1%, mGOS2­3 em 18,6%, e mGOS4­5 em 76,3%; aos 6 meses, mGOS1 em 10,2%, mGOS2­ 3 em 10,2%, e mGOS4­5 em 79,6%. Verificou-se uma correlação estatisticamente significativa entre aneurismas da basilar e um pior outcome (p » 0,011). Não se verificou qualquer correlação entre os valores da escala de H&H à admissão e o outcome. Conclusões O outcome funcional do nosso grupo de pacientes está em linha com o descrito noutras séries da literatura. Contudo, destaca-se uma tendência para uma mortalidade mais baixa, mas uma morbilidade mais alta no nosso grupo de pacientes.

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.

Aneurisma gigante de arteria iliaca interna roto / Giant ruptured internal iliac aneurysm

Objetivo: Presentar un caso infrecuente de aneurisma gigante de arteria iliaca interna roto. Caso clínico: Varón de 68 años de edad con antecedentes de hipertensión arterial crónica, dislipidemia, cardiopatía valvular, cor pulmonale con hipertensión pulmonar moderada, portador de marcapasos definitivo, obesidad y alergia a la plata. Ingresa de urgencia por dolor brusco en fosa iliaca izquierda, irradiado periumbilicalmente sin cortejo vegetativo. En el TC abdominal se objetiva la presencia de un aneurisma gigante de la arteria hipogástrica izquierda con diámetro de 6,8 cm y signos de rotura. Se realiza de forma urgente cirugía endovascular mediante implante de prótesis Endurant® y embolización de arterias glúteas con Coils Interlock®. Control al mes y a los 6 meses sin endofugas ni crecimiento del saco. Discusión: El tratamiento de elección de los aneurismas iliacos sigue siendo la cirugía, de forma electiva cuando el diámetro de la arteria es mayor de 3 cm y urgente cuando debutan con rotura. La terapia endovascular es una alternativa segura y eficaz a la cirugía convencional, con resultados satisfactorios a corto y medio plazo.

Aim: To present an infrequent broken giant Iliac artery aneurysms. Case report: In the current study, we report a case of a 68-year-old male patient with chronic high blood pressure, cholesterol, valvular heart disease, cor pulmonale, pacemaker, obesity and silver allergic. He presented sudden onset of abdominal pain. Computed tomography (CT) revealed a large ruptured left hypogastric aneurysm (diameter of 6.8 cm). Hypogastric aneurysm was repaired by an endovascular graft repair: Endurant® endogratf and coils embolization of gluteal arteries (Interlock®). The patient had a satisfactory clinical progression and recovery. At one and six months after the operation TC revealed not Type II endoleaks. Discussion: Isolated aneurysms of the iliac arteries are rare. Surgical treatment is recommended for iliac artery aneurysms larger than 3 cm. Endovascular repair is an attractive method to repair isolated iliac artery aneurysms with lower morbidity and mortality rates than open surgery.

Tratamiento quirúrgico de aneurisma de la arteria espinal posterior roto: reporte de un caso y revisión de la literatura / Surgical treatment of ruptured posterior spinal arteryaneurysm. case report and literature review

Los aneurismas de la arteria espinal posterior (AEP) se presentan en su gran mayoría asociados a patologías que generan aumento del flujo arterial como malformaciones o fístula arteriovenosas y también asociadas a enfermedades del colágeno. Su presentación aislada es rara, con 11 casos publicados en la literatura a nuestro conocimiento. Presentamos una paciente de 56 años de edad, usuaria de anticoagulantes orales por accidente cerebro vascular antiguo no secuelado secundario a fibrilación auricular, que se presenta con dolor lumbar súbito no irradiado, al que luego se agrega paraplejia fláccida. En resonancia nuclear magnética se observa hemorragia subaracnoidea espinal con importante compresión medular secundaria. Estudio con angiografía demostró aneursima de aspecto disecante en arteria espinal posterior. Debido a pequeño calibre de arteria nutricia se optó por tratamiento quirúrgico. Angiografia de control mostró exclusión completa de aneurisma. En los controles posteriores la paciente ha mostrado recuperación progresiva del déficit neurológico. Tanto el tratamiento endovascular como el quirúrgico se han reportado para la exclusión de aneurismas de la AEP. El presente caso muestra que el tratamiento quirúrgico precoz es una alternativa sobre todo si además se requiere realizar descompresión medular.

Aneurysms of the Posterior spinal artery (PSA) usually present secondary to high-flow pathologies such as arteriovenous malformations or dural arteriovenous fistulas, also can be associated whit collagen diseases. Isolate PSA aneurysms are rare, whit 11 cases reported, to our knowledge. We present a 56 years old patient, user of oral anticoagulant for an old isquemic stroke, secondary to atrial fibrillation, who presented whit subit lumbar pain and flaccid paraplejia. The magnetic resonance image shows an extensive spinal subarachnoid hemorrhage and secondary medular compression. Spinal angiography study demonstrated a dissecting aneurysm of PSA. Due to the small size of the artery, on which the aneurysm was located, surgical treatment was performed. Follow up angiography shows complete exclusion of the lesion. The patient has had a progressive recovery on her deficit. Both surgical and endovascular treatment have been reported. The present case shows that early surgical treatment is an option, especially if medular decompression is needed.
