Multicenter StudyA multicenter study of 705 ruptured intracranial aneurysms treated with Guglielmi detachable coils.
The long-term durability of Guglielmi detachable coil (GDC) embolization of cerebral aneurysms is still unknown. The purpose of this study was to evaluate the stability of anatomic occlusion of aneurysms treated with GDCs and assess the rate of recanalization and re-treatment. ⋯ Our multicenter study confirms the stability of aneurysm embolization with GDC, with only 4.7% of aneurysms requiring re-treatment.

Early rebleeding after coiling of ruptured cerebral aneurysms: incidence, morbidity, and risk factors.
The purpose of this study was to assess the incidence of early rebleeding after coiling of a ruptured cerebral aneurysm, assess the clinical outcome, and identify risk factors for this event. ⋯ Early rebleeding after coiling of ruptured aneurysms is a major concern, in particular because the mortality is very high. A more restricted postembolization anticoagulation strategy in high-risk aneurysms may possibly prevent the occurrence of this devastating event.

Angiographic assessment of pial collaterals as a prognostic indicator following intra-arterial thrombolysis for acute ischemic stroke.
This study examines whether anatomic extent of pial collateral formation documented on angiography during acute thromboembolic stroke predicts clinical outcome and infarct volume following intra-arterial thrombolysis, compared with other predictive factors. ⋯ Evaluation of pial collateral formation before thrombolytic treatment can predict infarct volume and clinical outcome for patients with acute stroke undergoing thrombolysis independent of other predictive factors. Thrombolytic treatment appears to have a greater clinical impact in those patients with better pial collateral formation.

Case ReportsAbciximab in patients with ruptured intracranial aneurysms.
Experience with intravenous abciximab to manage thromboembolism during treatment of ruptured intracranial aneurysms is limited. We present our experience in 13 patients. ⋯ Abciximab completely or partially treated thromboembolic complications arising during coiling of ruptured aneurysms. Further coiling should be performed with extreme caution and needs to be decided on a patient-by-patient basis.

Percutaneous vertebroplasty for metastatic involvement of the axis.
Percutaneous vertebroplasty in the upper cervical spine is a challenging procedure, and little is known about its therapeutic outcome. The purpose of this study was to assess the risks and benefits of percutaneous vertebroplasty for metastatic involvement of the axis. ⋯ Percutaneous vertebroplasty of C2 metastases by an antero-lateral approach is an effective option in the treatment strategy of patients with metastases to C2. Nevertheless, it is a challenging procedure and may carry regional and even intracranial risks due to the proximity to the vertebral artery.
