OBJECTIVE To analyze the immediate and midterm angiographic and clinical results of stent placement in the endovascular treatment of intracranial cerebral aneurysms. METHODS Out of 330 cerebral aneurysms treated by endovascular approach in our neurovascular centre, stents have been used in 18 patients. Twelve aneurysms (66.7%) were acutely ruptured, four (22.2%) were unruptured, two (11.1%) w...

BACKGROUND AND PURPOSE Flexible microstents, such as the closed-cell EN, have facilitated adjunctive coiling of intracranial aneurysms. Little data are available on the ability of the stent struts to maintain vessel-wall apposition once deployed in the tortuous cerebral vasculature and the prevalence of ISA. The purpose of this study was to evaluate the relationship between geometric features o...

BACKGROUND Surgical clipping or endovascular coiling are the main procedures used in the treatment of cerebral aneurysms, with a preference for endovascular coiling. In Morocco, the number of patients needing endovascular coiling is growing, but many of them do not have access to this technique. The aim of this study was to determine the main parameters associated with variations in the total c...

BACKGROUND AND PURPOSE Low-profile self-expandable stents were recently introduced for the treatment of wide-neck intracranial aneurysms. This study investigated the initial and midterm clinical and angiographic results of LEO Baby stent-assisted coiling in the treatment of wide-neck intracranial aneurysms. MATERIALS AND METHODS A retrospective review was performed to identify patients who we...

BACKGROUND Recurrence after intracranial aneurysm coiling is a highly prevalent outcome, yet to be understood. We investigated clinical, radiological and procedural factors associated with major recurrence of coiled intracranial aneurysms. METHODS We retrospectively analyzed prospectively collected coiling data (2003-12). We recorded characteristics of aneurysms, patients and interventional t...

When DNA-binding proteins search for their specific binding site on a DNA molecule they alternate between linear 1-dimensional diffusion along the DNA molecule, mediated by nonspecific binding, and 3-dimensional volume excursion events between successive dissociation from and rebinding to DNA. If the DNA molecule is kept in a straight configuration, for instance, by optical tweezers, these 3-di...
