[Usefulness of magnetic resonance angiography in surgery of ruptured intracranial aneurysms].
Cerebral angiography (CA) is considered as the gold standard in diagnosis of intracranial aneurysms; nevertheless, the magnetic resonance angiography (MR-angiography) is wide spread used in detection of unruptured aneurysm. For this reason, several authors had proposed that MR-angiography could replace CA in the diagnosis of ruptured aneurysms. ⋯ MR-angiography is an excellent no invasive method in the diagnosis of ruptured intracranial aneurysms, and could replace CA in selected cases.

[Stroke-specific quality of life scale (ECVI-38): an evaluation of its acceptance, reliability and validity].
Health-related quality of life (HRQL) is currently essential in the evaluation of stroke-related clinical trials. Existing stroke-specific scales were developed in English-speaking countries and most of them do not satisfy the necessary standards of validity. In consequence, the first Spanish-language scale for evaluating the quality of life (QL) of stroke survivors was developed (ECVI-38). In this work the psychometric properties of this summary measure were assessed. ⋯ The ECVI-38 is a measure that is acceptable, reliable and valid for evaluating QL in patients who have had a stroke. Further tests are needed to evaluate its sensitivity and to explore its value in both clinical and research practice.

[Patent foramen ovale and obstructive sleep apnea: their association and meaning].
The patent foramen ovale is a permanent aperture, similar to a floating membrane, remainder from fetal circulation. It can be easily diagnosed by transesophageal echocardiography and/or transcraneal Doppler with contrast. It is being described an increasing number of pathologies, where the presence of a patent foramen ovale can have pathologic significance. ⋯ Patients with obstructive sleep apnea present a major prevalence of patent foramen ovale than normal population. In these patients can easily concur, at least theoretically, the basic criteria for paradoxical embolism. In this study, we revised the pathologic implications that can derive from this association.
