Anterior Communicating Artery Aneurysm Uncommon Hemorrhagic Presentation: Case Report

Arq. bras. neurocir; 39 (1), 2020
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 intrac...

Relationship between Obesity and Coronary Artery Disease Defined by Coronary Computed Tomography Angiography

Abstract Background: Although associated with traditional cardiovascular risk factors, it is unclear whether obesity alone is associated with coronary artery disease (CAD). Objective: To investigate the role of obesity as a risk factor for CAD, defined by coronary computed tomography angiography (CCTA)...

The use of high-resolution MRI to detect thrombosis and lipid-rich carotid artery plaques in a patient with homozygous familial hypercholesterolemia

SUMMARY Homozygous familial hypercholesterolemia is a rarely agentic disorder of the lipoprotein metabolism intimately related to premature atherosclerotic cardiovascular disease that can lead to high disability and mortality. Homozygous familial hypercholesterolemia typically affects not only the aortic...

Membrana de circulación extracorpórea en shock obstructivo secundario a enfermedad linfoproliferativa
Oxygenation with extracorporeal membrane in obstructive shock secondary to lymphoproliferative disease

Medicina (B.Aires); 79 (6), 2019
La membrana de oxigenación extracorpórea arteriovenosa se utiliza cuando ocurre falla hemodinámica y respiratoria refractaria al tratamiento convencional; brinda soporte hemodinamico transitorio, oxigenacion y remocion de CO2, y permite reposo pulmonar. Asimismo ofrece la posibilidad de realizar venti...

Pseudoaneurisma postraumático de arteria femoral en una niña de dos años
Post-traumatic pseudoaneurysm of the femoral artery in a two-years- old girl

Introducción: Los aneurismas arteriales son poco frecuentes en edad pediátrica, sin embargo; se observa un incremento en la incidencia de pseudoaneurismas a partir de traumatismos vasculares, sobre todo, por la aplicación de procederes invasivos. También se observan en procesos infecciosos y tumoral...

Evaluation of Myocardial Perfusion by Computed Tomography - Principles, Technical Background and Recommendations

Arq. bras. cardiol; 113 (4), 2019
Abstract Coronary computed tomography angiography (CCTA) has gained a prominent role in the evaluation of coronary artery disease. However, its anatomical nature does not allow the evaluation of the functional repercussion of coronary obstructions. It has been made possible to evaluate Myocardial compute...

Arterial variations within the lateral cervical region: a multidetector CT angiography study

Int. j. morphol; 37 (3), 2019
It is important to know the arterial anatomy within the lateral cervical region before the flap-planning. We evaluated the arterial anatomy in this area using multidetector computed tomography (CT) angiography and our aim was to establish the arterial variations. Both sides of individuals in a total numb...

An augmented patient-specific approach to administration of contrast agent for CT renal angiography

Int. braz. j. urol; 45 (5), 2019
ABSTRACT Purpose This hybrid retrospective and prospective study performed on 200 consecutive patients undergoing renal CTA, investigates the opacification of renal vasculature, radiation dose, and reader confidence. Materials and Methods 100 patients were assigned retrospectively to protocol A and t...

Symptomatic aortic valve mass - cardiac work-up challenges and role of computed tomography angiography: a case report

Abstract Cardiac papillary fibroelastoma are rare, benign cardiac tumors that may lead to lethal complications from embolization or valvular dysfunction if left untreated. When working up symptomatic tumors with concomitant angina, traditional diagnostic studies such as cardiac catheterization may predis...

Correlação entre as lesões coronarianas diagnosticadas pela angiotomografia e as diagnosticadas pelo método visual da cineangiocoronariografia

Avaliar a eficácia diagnóstica da angiotomografia coronariana (AC) comparada com a cineangiocoronariografia (CAT). Material e Métodos: Foram avaliados retrospectivamente 146 pacientes submetidos a AC e CAT com angiografia coronariana quantitativa (ACQ), com intervalo médio de um mês entre os exames...
