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.

Tratamiento endovascular del aneurisma esplénico incidental y en la urgencia / Endovascular treatment of incidental and emergency splenic aneurysm

Resumen Los aneurismas esplénicos verdaderos son dilataciones saculares que involucran todas las capas de la arteria esplénica. Se presentan más frecuentemente en mujeres, en el embarazo y pacientes con hipertensión portal. Son habitualmente asintomáticos y diagnosticados incidentalmente durante el estudio de otra afección abdominal. Hasta un 10% se puede presentar con ruptura, lo que supone un escenario con una alta morbilidad y mortalidad. El tratamiento de los aneurismas esplénicos es aún un tema de controversia y existen variadas modalidades terapéuticas. Presentamos dos casos de pacientes con aneurismas esplénicos: uno de ellos que se manifestó con rotura y el otro por un diagnóstico incidental. Ambos fueron resueltos mediante embolización endovascular con resultados óptimos. Esta modalidad terapéutica poco difundida para el tratamiento de aneurismas esplénicos gigantes o rotos, nos permitió resolver el cuadro de forma segura y efectiva, con mínima morbilidad y mortalidad.

Abstract True splenic aneurysms are saccular dilations of all the layers of the splenic artery, more common in women, pregnancy and portal hypertension. They are usually asymptomatic and diagnosed incidentally during the study of other abdominal diseases. Up to 10% may present with rupture, which implies a high morbidity and mortality. Treatment of splenic aneurysms is still a subject of controversy and there is a great variety of therapeutic modalities. We present two cases of patients with splenic aneurysms: one who presented with rupture and the other one incidentally diagnosed. Both were treated with endovascular embolization achieving optimal results. Although the utility of this therapy has not been assessed for giant or ruptured aneurysms, it allowed us to solve these scenarios in a secure and effective way, with minimum morbidity and mortality.

Progress in the role of high resolution magnetic resonance imaging technology in the risk assessment of intracranial aneurysm rupture / 中南大学学报(医学版)

The traditional classification, diagnosis, and treatment of intracranial aneurysms are based on the characteristics of their vascular lumen. However, in the past few years, some advances in MRI technology with high-resolution imaging can assess the pathology of intracranial vascular walls. Compared with traditional methods of computed tomography angiography, magnetic resonance angiograhpy, and digital subtraction angiography, high resolution magnetic resonance imaging technology can help us to newly understand the disease by directly evaluating the characteristics of vascular wall, such as aneurysm wall thickness, inflammation, enhancement, permeability and hemodynamics. At present, high-resolution magnetic resonance imaging is increasingly used in clinic to assess the rupture risk of intracranial aneurysms, which is of great significance for guiding the diagnosis and treatment of intracranial aneurysms.

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.

Massive hemoptysis following Rasmussen's aneurysm: a case report

Rasmussen's aneurysm (RA) is a pseudoaneurysm of a pulmonary artery (AP), adjacent to or within a tuberculous cavity, appearing in 5% of these lesions. Its rupture might provoke massive hemoptysis (MH) with a near 50% mortality. The aim of this article is to report a case of massive hemoptysis following Rasmussen's aneurysm. 52-year-old man with recent history of hospita-lization due to pneumonia associated to influenza A and decompensated hyperthyroidism, pre-sents outpatient chest radiograph with signs of hyperinflation and scarring apical opacities, the patient returned to the hospital due to sharp pain of left hemi thorax during inspiration accom-panied with bloody sputum, asthenia and non-quantified weight loss. He evolves to frank MH, requiring endotracheal intubation managed in the intensive care unit (ICU). Chest computed tomography (CT) reported ground-glass opacity, nodules with a tendency to cavitation, tree-in-bud pattern in agreement with inflammation and infection, active TB is considered, and truncus of PA with vascular lesion suggestive of aneurysm dependent on pulmonary circulation, possibly RA. Fibrobronchoscopy reported signs of old and recent bleeding of left bronchial tree, probably of the lingula, blood clots in right bronchial tree. Molecular study and TB cultures was negative. Endovascular procedure with arteriography was carried out, revealing amputation of left distal segmental PA carrying the pseudoaneurysm with complete regression, discarding embolization RA It must be considered among the differential diagnoses of MH, especially on patients with pulmonary TB complications, such as the reported case. Due to its associated increased morta-lity, once RA is identified, it must be either endovascularly or surgically eradicated.

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.

Abdominal Apoplexy after Pulmonary Lobectomy for Lung Cancer / Apoplejía abdominal tras una lobectomía pulmonar por cáncer de pulmón

ABSTRACT Abdominal apoplexy is a rare clinical entity, and its clinical manifestations are diverse. This case report is of a 52-year-old man who developed right upper abdominal pain with unstable haemodynamics 32 hours after right upper pulmonary lobectomy for lung carcinoma. Abdominal computed tomography showed a ruptured right gastric artery aneurysm.

RESUMEN La apoplejía abdominal es una entidad clínica rara, y sus manifestaciones clínicas son diversas. Este es un reporte de caso de un hombre de 52 años que presentó dolor abdominal superior derecho con hemodinámica inestable, 32 horas después de una lobectomía pulmonar superior derecha por carcinoma del pulmón. La tomografía computarizada abdominal mostró una ruptura de aneurisma de la arteria gástrica derecha.

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.

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.

Resumo O aneurisma roto de aorta torácica descendente constitui uma situação ameaçadora associada a alta morbidade e mortalidade. O tratamento endovascular desse tipo de aneurisma promove exclusão eficaz com uma terapêutica minimamente invasiva. Os autores relatam o caso de um paciente do sexo masculino, 76 anos, hemodinamicamente instável, com aneurisma roto de aorta torácica descendente de 9 cm de diâmetro, tratado em caráter emergencial por cirurgia endovascular.

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.

Risk Factors for the Rupture of Bifurcation Intracranial Aneurysms Using CT Angiography

PURPOSE: To investigate the clinical and morphological characteristics in relation to risk of bifurcation intracranial aneurysm rupture. MATERIALS AND METHODS: Data from 202 consecutive patients with 219 bifurcation aneurysms (129 ruptured and 90 unruptured) managed at the authors' facility between August 2011 and July 2014 were retrospectively reviewed. Based on their clinical records and CT angiographic findings, the ability of risk factors to predict aneurysm rupture was assessed using statistical methods. RESULTS: Age, hypertension, diabetes mellitus, and cerebral atherosclerosis were negatively correlated with aneurysm rupture. Aneurysms located in the middle cerebral artery, daughter artery ratio, lateral angle ratio (LA ratio), and neck width were negatively correlated with rupture. Aneurysms located in the anterior communicating artery, irregularity, with daughter sac, depth, width, maximum size, aspect ratio (AR), depth-to-width ratio, and bottleneck factor were significantly and positively correlated with rupture. Binary logistic regression model revealed that irregular shape [odds ratio (OR) 6.598] and AR (OR 3.507) strongly increased the risk of bifurcation aneurysm rupture, while age (OR 0.434), cerebral atherosclerosis (OR 0.125), neck width (OR 0.771), and LA ratio (OR 0.267) were negatively correlated with rupture (p<0.05). Receiver operating characteristic analysis revealed the threshold values of AR and LA ratio to be 1.18 and 1.50, respectively. CONCLUSION: Age (≥60 yr), cerebral atherosclerosis, and aneurysms with a larger neck width and larger LA ratio are protective factors against bifurcation aneurysm rupture. An aneurysm with an irregular shape and an increased AR reflect the greater likelihood of a rupture.

Endovascular Treatment of a Ruptured Pulmonary Artery Aneurysm in a Patient with Behcet's Disease Using the Amplatzer Vascular Plug 4

A pulmonary artery aneurysm is a common manifestation and the leading cause of mortality in Behcet's disease. We describe a case of spontaneous rupture of a pulmonary artery aneurysm that, due to the inadequacy of medical therapy and the disadvantages of surgery, became the ideal candidate for endovascular management and was successfully performed by using the Amplatzer Vascular Plug 4.

The Endovascular Management of Saccular Posterior Inferior Cerebellar Artery Aneurysms

OBJECTIVE: The purpose of this retrospective study was to report the outcome of the endovascular treatment of eight patients with eight saccular posterior inferior cerebellar artery (PICA) aneurysms. MATERIALS AND METHODS: Over the last seven years (1999-2006), eight consecutive patients with saccular PICA aneurysms were treated by endovascular methods. Five of the aneurysms were presented with subarachnoid hemorrhaging, whereas three were discovered incidentally. Four of the aneurysms (3 ruptured and 1 incidental) were treated by intrasaccular coiling, whereas the remaining four (1 ruptured and 3 incidental) were treated by vertebral artery (VA) occlusion. RESULTS: Of the four aneurysms treated by intrasaccular coiling, three were completely packed with coils and one was partially packed. In three of four patients who underwent vertebral artery occlusions, follow-up digital subtraction angiographies demonstrated thrombosed aneurysms and PICA. No procedure-related morbidity occurred and no re-bleed was encountered during a follow-up examination (mean; 31 months). CONCLUSION: As a result of this study, we found that the endovascular management of saccular PICA aneurysms should be considered as safe and effective.

A Less Invasive Approach for Ruptured Aneurysm with Intracranial Hematoma: Coil Embolization Followed by Clot Evacuation

OBJECTIVE: The presence of an intracerebral hematoma from a ruptured aneurysm is a negative predictive factor and it is associated with high morbidity and mortality rates even though clot evacuation followed by the neck clipping is performed. Endovascular coil embolization is a useful alternative procedure to reduce the surgical morbidity and mortality rates. We report here on our experiences with the alternative option of endovascular coil placement followed by craniotomy for clot evacuation. MATERIALS AND METHODS: Among 312 patients who were admitted with intracerebral subarachnoid hemorrhage during the recent three years, 119 cases were treated via the endovascular approach. Nine cases were suspected to show aneurysmal intracerebral hemorrhage (ICH) on CT scan and they underwent emergency cerebral angiograms. We performed immediate coil embolization at the same session of angiographic examination, and this was followed by clot evacuation. RESULTS: Seven cases showed to have ruptured middle cerebral artery (MCA) aneurysms and two cases had internal carotid artery aneurysms. The clinical status on admission was Hunt-Hess grade (HHG) IV in seven patients and HHG III in two. Surgical evacuation of the clot was done immediately after the endovascular coil placement. The treatment results were a Glasgow Outcome Scale score of good recovery and moderate disability in six patients (66.7%). No mortality was recorded and no procedural morbidity was incurred by both the endovascular and direct craniotomy procedures. CONCLUSION: The results indicate that the coil embolization followed by clot evacuation for the patients with aneurysmal ICH may be a less invasive and quite a valuable alternative treatment for this patient group, and this warrants further investigation.

With prompt and urgent management the patient survived

Three-dimensional digital subtraction angiography vs two-dimensional digital subtraction angiography for detection of ruptured intracranial aneurysms: a study of 86 aneurysms.

AIMS: Three-dimensional reconstruction of intracranial vessels is of interest for evaluation of aneurysms. This study determined diagnostic difference of three-dimensional digital subtraction angiography (3D-DSA, volume-rendering image) versus 2D-DSA for evaluating ruptured intracranial aneurysms, particularly focusing on the size of aneurysms as depicted in both images. SETTINGS AND DESIGN: Sixty-nine patients underwent 3D-DSA and 2D-DSA. The relative size of an aneurysm, which is the ratio of the maximal diameter of an aneurysm to the diameter of a major vessel, was compared between imaging techniques. In addition, relative sizes of smaller aneurysms (< 5 mm) were compared with those of larger aneurysms (>10 mm). Statistical analysis used: For comparison of aneurysm size and location of aneurysm, statistical analysis was performed with the Yates chi square test; statistical significance was set with a P value of less than 0.05. RESULTS: Sixty-three (73.3%) of the 86 total aneurysms were bigger when measured with 3D-DSA versus 2D-DSA. When measured with 3D-DSA, 28 (84.8%) of the 33 smaller aneurysms were bigger, and 50% of the larger aneurysms were bigger versus measurements of 2D-DSA images (P < 0.05). In ACA and ICA territories, which tended to have smaller mean aneurysmal size, relative size of the aneurysm was bigger when measured with 3D-DSA (81.5% and 81.0%, respectively). In MCA, where the mean aneurysmal size was the largest, relative size of aneurysms was bigger when measured with 3D-DSA in 15 cases (53.6%, P < 0.05). In the posterior circulation, aneurysm size was similar between 3D-DSA and 2D-DSA measurements. CONCLUSIONS: 3D-DSA, especially volume-rendering images, tends to depict ruptured intracranial aneurysms bigger than 2D-DSA. This is particularly true with cerebral aneurysms that are < 5 mm in size and are located in the anterior circulation, especially ICA and ACA territories.
