Background and Purpose: The relationship between aneurysm dimensions, flow, thrombosis, and rupture remains poorly understood. We attempted to clarify this relationship by exploring various swine aneurysm models.
Background and Purpose: The best approach between general anesthesia and conscious sedation to perform mechanical thrombectomy remains unknown. The goal of our study was to evaluate the feasibility, safety, and efficacy of mechanical thrombectomy under conscious sedation in patients with acute ischemic stroke, using the Solitaire FR device, in a prospective, single-center, single-arm study.
Background and Purpose: Revascularization of large cerebral artery occlusion is the therapeutic goal in stroke therapy. Currently, many recanalization devices are in clinical use. This study compares the outcome parameters, efficacy, and safety of the new generation of stent-retriever devices with the well-established Merci retriever.
Background and Purpose: Flow-diverting stents, such as the PED, have emerged as a novel means of treating complex intracranial aneurysms. This retrospective analysis of the initial Canadian experience provides insight into technical challenges, clinical and radiographic outcomes, and complication rates after the use of flow-diverting stents for unruptured aneurysms.
Background and Purpose: The use of arterial closure device in patients with prolonged high ACT values has not been extensively studied. The aim of this study was to compare the safety and efficacy of an arterial closure device, Angio-Seal, with manual compression in patients on anticoagulation following neurointerventional procedures.
Background and Purpose: Acute BAO is a devastating neurological condition associated with a poor clinical outcome and a high mortality rate. Recanalization has been identified as a major prognostic factor for good outcome in BAO. Mechanical thrombectomy using retrievable stents is an emerging treatment option for acute stroke. First clinical trials using stent retrievers have shown promising high recanalization rates. However, these studies mainly included large artery occlusions in the anterior circulation with only a few or single cases of BAO. Therefore, the purpose of this study was to evaluate technical feasibility, safety, and efficacy of mechanical thrombectomy using retrievable stent in the treatment of acute BAO.
Objectives: The goal of this study was to analyze the impact of dabigatran plasma concentrations, patient demographics, and aspirin (ASA) use on frequencies of ischemic strokes/systemic emboli and major bleeds in atrial fibrillation patients.
Background: Blister aneurysms of the internal carotid artery (ICA) are uncommon. There is a paucity of data on the long-term outcomes of patients.
Background: Whether the addition of stenting to intracranial aneurysm coil embolization results in benefit in terms of occlusion rates or additional risk in terms of periprocedural adverse events is not clear.
Background: It is not known what effect pregnancy or delivery has on the risk of rupture of an intracranial aneurysm, and, consequently, the optimal management of unruptured aneurysms in pregnancy is unclear.
Background and Importance: Purely intraorbital arteriovenous fistulas (AVFs), which are rare vascular malformations that clinically mimic carotid-cavernous fistulas (CCFs), involve a fistula from the ophthalmic artery to 1 of the draining ophthalmic veins. We describe a case of an intraorbital AVF treated with transvenous endovascular coil embolization via the inferior petrosal sinus (IPS) route and review the literature on this rare entity.
Background: Arteriovenous malformation (AVM) treatment is multidisciplinary, and the patient may undergo embolization, neurosurgery, or radiosurgery combined. Great improvement in endovascular techniques was provided by the introduction of Onyx with different kinds of approach.
Background: Microsurgical clip obliteration remains a time-honored and viable option for the treatment of select aneurysms with very low rates of recurrence.
Background: The association of carotid body paragangliomas with neurovascular structures can cause cranial nerve injury and significant intraoperative blood loss. Preoperative embolization may be performed either percutaneously or transarterially.
Background and Importance: Olfactory tract dysfunction due to an unruptured intracranial aneurysm is rare. We present a case in which a patient with impaired olfaction related to bilateral internal carotid artery aneurysms experienced subjective and quantitative objective improvement of olfactory sensation after treatment of ophthalmic segment aneurysms with flow diversion.
