Introduction: The most significant factors leading to restenosis are yet to be described in the literature. The purpose of our study was to identify the incidence of restenosis in our patients with carotid artery stenting (CAS) for carotid atherosclerotic disease and to identify risk factors that are significantly responsible or related to the restenosis.

Background and Purpose—Early decompressive surgery in patients with malignant middle cerebral artery (MCA) infarction improves outcome. Elevation of intracranial pressure depends on both the space occupying brain edema and the intracranial volume reserve (cerebrospinal fluid [CSF]). However, CSF volume was not investigated as a predictor of malignant infarction so far. We hypothesize that assessment of CSF volume in addition to admission infarct size improves early prediction of malignant MCA infarction.

BACKGROUND: Anatomic diversity among cerebellar arteriovenous malformations (AVMs) calls for a classification that is intuitive and surgically informative. Selection tools like the Spetzler-Martin grading system are designed to work best with cerebral AVMs but have shortcomings with cerebellar AVMs. OBJECTIVE: To define subtypes of cerebellar AVMs that clarify anatomy and surgical management, to determine results according to subtypes, and to compare predictive accuracies of the Spetzler-Martin and supplementary systems.

BACKGROUND AND PURPOSE: Carotid artery–related stroke is largely an embolic disease that has been correlated with inflammation, plaque rupture, and thrombus formation in “vulnerable” atherosclerotic plaque. Nevertheless, current guidelines for carotid revascularization in asymptomatic patients rely on the calculation of stenosis for risk assessment, a parameter that has been viewed with increasing skepticism. Intravascular OCT is an imaging technique that offers high axial resolution (10 μm), allowing an unprecedented micron-level assessment of human carotid plaque morphology. This observational article reports the first successful use of the newest iteration of this technology, FDOCT without balloon occlusion to assess human carotid artery disease and carotid stent-vessel interaction in vivo.

Introduction: Endovascular treatment of intracranial aneurysms has been an effective treatment option. In this paper, we report our experience with the Silk stent (SS) for endovascular treatment of complex intracranial aneurysms and present periprocedural events, immediate results, delayed complications, and imaging and clinical follow-up results.

Background and Purpose—Management of asymptomatic unruptured intracranial aneurysms remains controversial, and recent prospective follow-up studies showed that the rupture rate of small aneurysms is very low. These results are inconsistent with the finding that the majority of ruptured aneurysms in patients with subarachnoid hemorrhage are small.

Background and Purpose—It is important to know the costs of hospitalization for patients undergoing endovascular embolectomy so that comparisons can be made with payments to hospitals. 2011; 42: 3271-3273 Published online before print October 6, 2011, doi: 10.1161/STROKEAHA.111.618405.

Introduction: This study aimed to evaluate long-term stabilizing healing effectiveness and influence on adjacent intact vertebral bodies of a new injectable partly resorbable calcium sulfate (60 wt.%)/hydroxyapatite (40 wt.%) bone substitute employed in vertebral augmentation of osteoporotic collapses.

BACKGROUND: In an era of indocyanine angiography, the routine use of intraoperative angiography (IOA) in the surgical treatment of aneurysms and vascular malformations is controversial. OBJECTIVE: To retrospectively assess the safety and efficacy of IOA and to determine predictors of surgical revision.

Introduction: Timely recanalization during endovascular procedures for acute ischemic stroke can be challenging in cases with large clot burden, such as those encountered in the terminal internal carotid T- or L-type occlusion.

Background and Purpose—Previous studies have demonstrated a strong correlation between treatment time and outcomes after intravenous recombinant tissue-type plasminogen activator. However, the temporal profile of ischemia may vary according to the level of occlusion, and it is likely that more proximal occlusions have a more variable temporal course than their distal counterparts. We sought to establish how time influences outcomes in anterior circulation proximal arterial occlusions.

Background and Purpose—The risk of ischemic stroke in patients with asymptomatic vertebral artery stenosis is unknown. We examined the incidence of posterior circulation ischemic stroke in patients with asymptomatic stenosis of the vertebral artery origin (VAo).

BACKGROUND: The standard treatment of resected brain metastasis is whole-brain radiotherapy (WBRT). To avoid the potential toxicity of WBRT and to improve local control, we have used radiosurgery alone to the surgical cavity. OBJECTIVE: To demonstrate the rates of local control, new intracranial metastasis, and overall survival using this treatment scheme without WBRT.

BACKGROUND AND PURPOSE: Development of a headache after aneurysm coil embolization is not uncommon but has received little attention. The authors prospectively analyze the characteristics and risk factors of a headache after coiling in patients treated for an unruptured cerebral aneurysm.

Introduction: Aneurysms superiorly located on the proximal segment of the middle cerebral artery (PMCAA) are rare and challenging to treat. No information is available regarding their management by endovascular approach. The aim of this study was to report our experience with endovascular treatment (EVT) of PMCAA.
