Introduction: Thromboembolic complications are the most frequent complications of endovascular treatment of ruptured intracranial aneurysms. The optimal protocol to prevent thromboembolic complications during coil embolization does not yet exist. The aim of this study was to investigate the effectiveness and safety of eptifibatide for the prevention of thromboembolic complications during elective coil embolization of ruptured cerebral aneurysms.
Introduction: The timing of definitive aneurysm treatment (coiling or clipping) in poor-grade (Hunt-Hess IV or V) subarachnoid haemorrhage (SAH) patients has been a controversial topic. The purpose of this retrospective study was to analyse whether ultra-early coiling of ruptured intracranial aneurysms improves the clinical outcomes of poor-grade SAH patients.
Introduction: Vein of Galen malformation (VGM) is the severest paediatric neurovascular disease usually requiring multiple staged embolisations. In the high-risk group of children with high-flow arteriovenous shunts, timing of treatment is uncertain. Low Doppler resistance index (RI) is known to be associated with adverse outcome in hypoxic-ischaemic brain injury in children. In this study, we want to present our long-term results of cranial transfontanellar Doppler ultrasound in children with VGM.
Introduction: Despite the variable anatomy of the anterior communicating artery (AcoA) complex, three main perforating branches can be typically identified the largest of which being the subcallosal artery (ScA). We present a case series of infarction in the vascular territory of the ScA to highlight the anatomy, the clinical symptomatology, and the presumed pathophysiology as it pertains to endovascular and surgical management of vascular pathology in this region.
Introduction: Endovascular treatment of large, wide-necked intracranial aneurysms with coils is associated with low rates of initial angiographic occlusion and high rates of recurrence. The Pipeline™ Embolization Device has shown high rates of complete occlusion in uncontrolled clinical series.
Introduction: The purpose of our study was to compare the clinical characteristics and preferential localization of aneurysms in three patient groups: single aneurysm, non-mirror multiple aneurysms, and mirror aneurysms.
BACKGROUND: Hurler disease (mucopolysaccharidosis type I [MPS-I]) is an inherited metabolic disorder characterized by deficiency of the lysosomal enzyme α-L-iduronidase (IDUA). Currently, the only therapies for MPS-I, enzyme replacement and hematopoietic stem cell transplantation, are generally ineffective for central nervous system manifestations.
BACKGROUND: Current American Heart Association guidelines recommend carotid revascularization for asymptomatic patients on the basis of life expectancy.
BACKGROUND: The endovascular treatment of middle cerebral artery (MCA) aneurysms has been controversial because of the frequency of complex anatomy and the relative ease of surgical clipping in this location.
OBJECT: The surgical treatment of many large arteriovenous malformations (AVMs) is associated with substantial risks, and many are considered inoperable. Furthermore, AVMs larger than 3 cm in diameter are not usually treated with conventional single-session radiosurgery encompassing the entire AVM volume. Volume-staged stereotactic radiosurgery (VS-SRS) is an option for large AVMs, but it has mixed results. The authors report on a series of patients with high-grade AVMs who underwent multiple VS-SRS sessions with resultant downgrading of the AVMs, followed by resection.
OBJECT: The goal of this study was to evaluate the obliteration rate of intracranial dural arteriovenous fistulas (DAVFs) in patients treated with stereotactic radiosurgery (SRS), and to compare obliteration rates between cavernous sinus (CS) and noncavernous sinus (NCS) DAVFs, and between DAVFs with and without cortical venous drainage (CVD).
OBJECT: A visual field deficit resulting from the management of an arteriovenous malformation (AVM) significantly impacts a patient´s quality of life. The present study was designed to investigate the clinical and radiological outcomes of stereotactic radiosurgery (SRS) performed for AVMs involving the postgeniculate visual pathway.
OBJECT: It was initially considered safe for flow-diverting stents to cover the ostia of branching vessels during endovascular procedures for the treatment of intracranial aneurysms. As more recent evidence suggests, however, their use is not always free of ischemic concerns in terms of covered arterial ostia. The authors sought to determine the frequency of silent and clinically evident diffusion-weighted imaging (DWI)–detected abnormalities related to stent placement as a means of elucidating potential clinical risks.
OBJECT: Tobacco smoking is one of the most important risk factors for the formation of intracranial aneurysms and for aneurysmal subarachnoid hemorrhages. Smoking has also been suggested to contribute to the recurrence of aneurysms after endovascular coiling. To improve the understanding of the impact of smoking on long-term outcomes after coil embolization of intracranial aneurysms, the authors studied a consecutive contemporary series of patients treated at their institution. The aims of this study were to determine whether smoking is an independent risk factor for aneurysm recurrence and retreatment after endovascular coiling.
OBJECT: Intraprocedural rerupture (IPR) of intracranial aneurysms during coil embolization is associated with significant periprocedural disability and death. However, whether this morbidity and mortality are secondary to an increased risk of vasospasm and hydrocephalus is unknown. The authors undertook this study to determine the in-hospital and long-term neurological outcomes for patients with aneurysmal subarachnoid hemorrhage (SAH) treated with coil embolization who suffer aneurysm rerupture during treatment.
