INTRODUCTION Although the diagnosis of brain death (BD) is usually based on clinical criteria, in sedated patients, ancillary techniques are needed. This study was designed to assess the accuracy of cerebral multislice computed tomographic angiography (CTA) and CT perfusion (CTP) in diagnosing BD. METHODS Prospective observational study in 27 BD patients.(More)
BACKGROUND The Pipeline Flex embolization device has some peculiarities in comparison with the previous generation device. Despite recent reports of the modified delivery system, its safety is still unknown. OBJECTIVE To illustrate the intraprocedural and periprocedural complication rate with this new device in 30 consecutive patients. MATERIAL AND(More)
Treatment of very small ruptured cerebral aneurysms (< 2 mm) continues to present a challenge. These lesions are difficult to treat both with neurosurgical and endovascular techniques. A neurosurgical approach is still the treatment of choice for these lesions at many centers because of high rupture rates related to endovascular treatment; however, there(More)
BACKGROUND Carotid dissection (CD) may, in certain cases, lead to significant stenosis, occlusion, or pseudoaneurysm formation, causing embolic stroke or hemodynamic failure, despite medical therapy. OBJECTIVE To evaluate the results of endovascular treatment and clinical outcomes of patients with CD. METHODS A four-hospital retrospective study of(More)
BACKGROUND Intravenous thrombolysis with alteplase is an effective treatment for ischaemic stroke when applied during the first 4.5 hours, but less than 15% of patients have access to this technique. Mechanical thrombectomy is more frequently able to recanalise proximal occlusions in large vessels, but the infrastructure it requires makes it even less(More)
This paper presents an automatic process to load the transport information of Lima-Peru city as network and public transportation routes from OpenStreetMap (OSM) to a PostgreSQL database. Moreover, this work shows how OSM data is transformed in two graphs and in several actual bus routes. The work is a combination of SQL commands and python programs to(More)
BACKGROUND AND PURPOSE The aim of our study was to evaluate the safety and efficacy of the pipeline endovascular device for the treatment of anterior circulation aneurysms at the level of the circle of Willis and beyond. METHODS A consecutive series of 25 patients (24 unruptured and one ruptured) with anterior circulation aneurysms treated with a pipeline(More)
BACKGROUND Flow diverter stents (FDS) have been described as a breakthrough in the treatment of intracranial aneurysms. Of the various flow diverter models, the Pipeline device has been the main approved and used device, with established and good long-term results. OBJECTIVE To present the first series of patients treated with its new version, the(More)
