Multicenter Study
Endovascular treatment of intracranial aneurysms using Matrix coils: short- and mid-term results in ruptured and unruptured aneurysms.
A prospective multicenter registry was conducted in France to evaluate the safety and efficacy of Matrix coils (Boston Scientific Neurovascular, Fremont, CA). The short- and mid-term results are presented. ⋯ In-hospital and 1-year morbidity and mortality rates in patients harboring ruptured or unruptured aneurysms treated with Matrix coils were similar to those previously reported with the use of bare coils. The efficacy of Matrix coils to prevent aneurysm recanalization was not demonstrated, despite a high percentage of progressive thrombosis that suggests biological activity resulting from Matrix coils.

Multicenter Study
Lower pretreatment cerebral blood volume affects hemorrhagic risks after intra-arterial revascularization in acute stroke.
Intra-arterial therapies are being used more frequently in patients presenting with acute cerebral occlusions, but they have been limited by the potential for hemorrhage. We sought to determine whether pretreatment computed tomography perfusion parameters might help to identify patients at a higher risk of developing intracranial hemorrhage after intra-arterial stroke revascularization treatment. ⋯ A reduced pretreatment ipsilateral cerebral blood volume value before endovascular revascularization of an acute middle cerebral artery or internal carotid artery occlusion significantly increases the risk of an intracranial hemorrhage.
