Object: Cerebral cavernous malformations have been studied widely, but the natural history of brainstem cavernous malformations (CMs) is not well defined, and hemorrhages caused by brainstem CMs are devastating. The goal of this study was to quantify the hemorrhage risks and functional outcomes of patients with brainstem CMs.
Background: The benefit of statins in patients with acute aneurysmal subarachnoid haemorrhage is unclear. We aimed to determine whether simvastatin 40 mg could improve the long-term outcome in patients with this disorder.
Background: The IMS III trial did not show a clinical benefit of endovascular treatment compared with intravenous alteplase (recombinant tissue plasminogen activator) alone for moderate or severe ischaemic strokes. Late reperfusion of tissue that was no longer salvageable could be one explanation, as suggested by previous exploratory studies that showed an association between time to reperfusion and good clinical outcome. We sought to validate this association in a preplanned analysis of data from the IMS III trial.
Background and Purpose: Parenchymal blood volume measurement by C-arm CT facilitates in-room peritherapeutic perfusion evaluation. However, the radiation dose remains a major concern. This study aimed to compare the radiation dose of parenchymal blood volume measurement using C-arm CT with that of conventional CTP using multidetector CT.
Objectives: The goal of this study was to investigate carotid plaque characteristics in symptomatic versus asymptomatic patients with the use of nonocclusive optical coherence tomography (OCT).
Background: Numerous reports have shown the relationship between carotid artery atherosclerosis and coronary artery disease (CAD). However, the association between complex CAD evaluated by SYNTAX score (SxScore) and prevalence of carotid lesion (CL) has not been fully investigated. We sought to assess the prevalence of carotid atherosclerosis in patients with multivessel CAD assessed by SxScore and the relationship between SxScore severity and features of carotid atherosclerosis.
Object: Using a database that enabled longitudinal follow-up, the authors assessed the long-term outcomes of unruptured cerebral aneurysms repaired by clipping or coiling.
Object: The purpose of this study was to report the authors´ experiences in stent-assisted coil embolization (SAC) of ruptured wide-necked aneurysms in the acute period and to evaluate the incidence of and risk factors for periprocedural complications.
Object: There is limited information regarding patient outcomes following interventions for stroke during the window for endovascular therapy. Studies have suggested that recently approved stent retrievers are safer and more effective than earlier-generation thrombectomy devices. The authors compared cases in which the Solitaire-FR device was used to those in which a MERCI or Penumbra device was used.
Background: Embolic protection devices may decrease periprocedural thromboembolic complications during carotid angioplasty and stenting (CAS). When using proximal-protection devices (PPDs), protection starts before crossing the lesion. However, in the medical literature, its use is scarcely reported compared with that of distal-protection filters (DPDs). The objective of this study was to compare periprocedure complications, morbidity, and mortality among 287 consecutive cases of CAS performed with PPDs or DPDs.
Purpose: To determine the safety and efficacy of endovascular therapy for the treatment of basilar artery dissection (BAD).
Purpose: Endovascular management with good preservation of the internal carotid artery (ICA) has become the first-line choice for the treatment of direct carotid cavernous fistulas (CCFs). Multiple treatments have been tried with variable success. This article elucidates the effectiveness and safety of embolization with Onyx and coils under transarterial balloon protection.
Background and Purpose: In past years, thrombectomy has become a widely used procedure in interventional neuroradiology for the treatment of acute intracranial occlusions. However, in 10–20% of patients, there are additional occlusions or stenotic lesions of the ipsilateral cervical internal carotid artery. The purpose of this study was to evaluate the feasibility of emergency carotid artery stent placement in combination with intracranial thrombectomy and the clinical outcome of the treated patients.
Background and Purpose: Acute occlusion of the ICA is often associated with poor outcomes and severe neurologic deficits. This study was conducted to evaluate outcome of the occluded ICA and efficacy of recanalization under protective flow arrest.
Background and Purpose: Previous studies have demonstrated that socioeconomic disparities in the treatment of cerebrovascular diseases exist. We studied a large administrative data base to study disparities in the utilization of mechanical thrombectomy for acute ischemic stroke.
