Introduction: Acute ischemic strokes with tandem occlusions, which represent 10-20% of all ischemic strokes, have a particularly poor prognosis. Since emergent treatment of tandem lesions has not been specifically addressed in randomized trials, there is an absence of standardized management.
Objective: We sought to assess the efficacy and safety of acute endovascular treatment in stroke due to tandem occlusions in our center and compare the results with previous reports.
Article Synopsis
- The Neuroform Atlas Stent System is a new hybrid device designed for treating unruptured aneurysms, combining elements of both open and closed cell stents.
- A study involving 30 patients showed the stents were successfully delivered and positioned in 29 cases, with most aneurysms demonstrating significant improvement post-treatment.
- The Atlas stent is safe and easy to implant with fewer complications compared to other stents, but its low thrombogenic potential may result in incomplete aneurysm occlusion over time.
Objective: The purpose of this study is to demonstrate our experience in endovascular reconstruction of carotid dissections using the Wingspan Stent System™ (Boston Scientific, Natick, MA, USA), a device we use because of its high radial force and its navigation in extreme curves.
Methods: We treated 11 consecutive patients with acute ischemic stroke due to carotid dissection with the Wingspan stent, in the cervical carotid artery.
Results: Functional evaluation revealed that 10 of the 11 patients were independent at 3 months post surgery and that the 11 stents used were found to be patent at the 6-month follow-up digital subtraction angiography (DSA).
Objective: The objective of this article is to compare the results of endovascular treatment of ruptured middle cerebral artery (MCA) aneurysms with ruptured aneurysms of other anatomic locations.
Methods: Fifty consecutive ruptured aneurysms of the MCA and 209 aneurysms at other anatomical locations were selected retrospectively. We compared epidemiological, clinical and radiological variables, prognosis and complications.
Object: To present a series of ruptured cerebral aneurysms in consecutive non-selected patients treated with endovascular therapy, analyzing the initial degree of occlusion, its anatomical evolution mid-term and the variables that could statistically affect them.
Methods: 251 aneurysms were first treated with coiling (embolization). 203 patients were followed up with conventional angiography for 6-8 months after the initial treatment and 182 were followed up with three-dimensional time of flight MR angiography at 18-24 months.

We report the case of a young patient with subarachnoid haemorrhage secondary to a ruptured blister-like aneurysm. Since this kind of aneurysms have fragile walls without a well-defined neck, their treatment is difficult. We initially planned the deployment of a flow-diverter stent, but an angiogram obtained after 10 days revealed a morphological change of the aneurysm.

Aim: To analyse the effectiveness and safety of the endovascular treatment of carotid stenosis in the Hospital Universitario Central de Asturias.
