Cervical Carotid Pseudo-occlusions And False Dissections: Intracranial Occlusions Masquerading As Extracranial Occlusions
(Lippincott Williams & WilkinsPhiladelphia, 2017)
Correlation between carotid bifurcation calcium burden on non-enhanced CT and percentage stenosis, as confirmed by digital subtraction angiography
(BRITISH INST RADIOLOGYLONDON, 2012)
Objectives: Previous evidence supports a direct relationship between the calcium burden (volume) on post-contrast CT with the percent internal carotid artery (ICA) stenosis at the carotid bifurcation. We sought to further ...
Sildenafil for treating patients with COVID-19 and perfusion mismatch: a pilot randomized trial
(BMC, 2022)
Background: SARS-CoV-2 seems to afect the regulation of pulmonary perfusion. Hypoperfusion in areas of well-aerated lung parenchyma results in a ventilation–perfusion mismatch that can be characterized using subtraction ...

Angiorresonancia versus angiografía por sustracción digital en el seguimiento de aneurismas intracraneales embolizados. Comparación del desempeño diagnóstico
(Universidad del RosarioEspecialización en RadiologíaFacultad de Medicina, 2015)
Introduction: DSA is the method of choice to follow patients with embolized intracranial aneurysms; it may be associated with disabling or fatal complications. The MRA has been proposed as an alternative because has less ...
Diagnóstico imagenológico de aneurismas cerebrales en pacientes con hemorragia subaracnoidea correlación de hallazgos en angiografía cerebral por tomografía computarizada helicoidal y angiografía cerebral por substracción digital
(Universidad Autónoma de Bucaramanga UNABFacultad Ciencias de la SaludEspecialización en Radiología e Imágenes Diagnósticas, 2005)
La hemorragia subaracnoidea no traumática (HSA) debida a la ruptura de un aneurisma cerebral es un evento catastrófico asociado con altas tasas de morbilidad y mortalidad. Es un problema clínico mayor con una incidencia ...
Anatomía básica de la circulación cerebral posterior
(Fundación Universitaria SanitasColombia, 2018-11)
Conocer la anatomía es un requisito indispensable para la interpretación de cualquier estudio imagenológico. Actualmente se cuenta con diversas modalidades diagnósticas como la angiografía por sustracción digital (ASD), ...
Angiografía cerebral por tomografía en el diagnóstico de aneurismas cerebrales en pacientes con hemorragia subaracnoidea
(Universidad Autónoma de Bucaramanga UNABFacultad Ciencias de la SaludPregrado Medicina, 2006-08-06)
El 85% de los casos de hemorragia subaracnoidea no traumática (HSA) es secundaria a ruptura de un aneurisma intracraneano. Su identificación y localización temprana permiten intervenir al paciente con miras a ...
Usefulness of the three-dimensional computed tomography angiography in the control of clipped cerebral aneurysms presenting with subarachnoid hemorrhage [Valor de la angiotomografía tridimensional en el control post-clipaje de los aneurismas cerebrales que se presentan con hemorragia subaracnoidea]
(2010)
Introduction: Three-dimensional CT angiography (3DCTA) in diagnosis of cerebral aneurysms has replaced the invasive, but traditional catheter-based method of intra-arterial digital subtraction angiography (IADSA). This ...
Serum C-reactive protein levels predict neurological outcome after aneurysmal subarachnoid hemorrhage
(ASSOC ARQUIVOS NEURO- PSIQUIATRIASAO PAULO SP, 2012)
Objectives: Our aim was to evaluate the relationship between serum C-reactive protein (CRP) levels and the neurological prognosis and development of vasospasm in patients with aneurysmal subarachnoid hemorrhage (aSAH). ...
