Moyamoya syndrome is a rare cerebrovasculopathy of unknown etiology which is associated with multiple risk factors. Moyamoya was first discovered in Japan and is reported to have an increased prevalence in the Japanese population. The term "Moyamoya" translates into "puff of smoke" and is named after the finding of the collateral cerebral vasculature that develops secondary to occlusion of an internal carotid artery at the entrance into the circle of Willis. This collateral vasculature characterizes the disease...

BACKGROUND AND PURPOSE: Stent retriever thrombectomy and manual aspiration thrombectomy (MAT) have each been shown to lead to high rates of recanalization as single-modality endovascular stroke therapy. We sought to describe the safety and efficacy of a multimodal approach combining these two techniques termed 'stent retriever-mediated manual aspiration thrombectomy' (SMAT) and compared them to MAT alone. METHODS: Retrospective review of a prospectively acquired acute endovascular stroke database...

Background Predicting recanalization success for patients undergoing endovascular treatment for acute ischemic stroke is of significant interest. Studies have previously correlated the success of recanalization with the density of the clot. We evaluated clot density and its relationship to revascularization success and stroke etiology. Methods We conducted a retrospective review of 118 patients undergoing intra-arterial therapy for acute ischemic stroke. Mean and maximum thrombus density was measured by drawing a circular region of interest on an axial slice of a non-contrast computed tomography scan...

Hemorrhagic complication is one of the notable surgical complications of the revascularization surgery for moyamoya disease (MMD). Cerebral hyperperfusion (CHP) has been considered as the underlying cause of this complication. It mostly occurs several days after surgery, but the intra-operative hemorrhage immediately after bypass has not been reported previously. A 21-year-old woman presented right thalamic hemorrhage and was diagnosed as having MMD by cerebral angiography. In light of the location of the hemorrhage at the vascular territory of posterior circulation and the manifestation of transient ischemic attack during the follow-up period, she underwent revascularization surgery to prevent future ischemic attack and rebleeding...

REVIEW
Jonathan J Liu, Gary K Steinberg
Moyamoya disease is a progressive occlusive vasculopathy that involves the supraclinoid internal carotid arteries and Circle of Willis, and results in the formation of collateral vessels at the skull base. The progressive nature of this disease leads to cerebral ischemia and sometimes intracerebral hemorrhage. The treatment of moyamoya disease is mainly surgical revascularization, using revascularization techniques that include direct, indirect, and combined strategies. Here we discuss the available options for revascularization as well as our opinions regarding the surgical management of patients with moyamoya disease...

OBJECTIVE After internal carotid artery (ICA) sacrifice without revascularization for complex aneurysms, ischemic complications can occur. In addition, hemodynamic alterations in the circle of Willis create conditions conducive to the formation of de novo aneurysms or the enlargement of existing untreated aneurysms. Therefore, the revascularization technique remains indispensable. Because vessel sizes and the development of collateral circulation are different in each patient, the ideal graft size to prevent low flow-related ischemic complications (LRICs) in external carotid artery (ECA)-middle cerebral artery (MCA) bypass with therapeutic ICA occlusion (ICAO) has not been well established...

De novo aneurysms associated with superficial temporal artery (STA)-middle cerebral artery (MCA) bypass are an extremely rare complication of direct revascularization surgery for moyamoya disease (MMD). The basic pathology of MMD includes fragility of the intracranial arterial wall characterized by medial layer thinness and waving of the internal elastic lamina. However, the incidence of newly formed aneurysms at the site of anastomosis currently remains unknown. Among 317 consecutive direct/indirect combined revascularization surgeries performed for MMD, we encountered a 52-year-old woman manifesting a de novo aneurysm adjacent to the site of anastomosis 11 years after successful STA-MCA bypass with encephalo-duro-myo-synangiosis (EDMS)...

BACKGROUND: This is the first report of the successful treatment of moyamoya disease (MMD) and an unruptured intracranial aneurysm in a patient with Floating-Harbor Syndrome (FHS). CASE DESCRIPTION: A 35 year-old, phenotypically syndromic woman presented with signs and symptoms consistent with ischemic stroke. MRI and catheter angiography confirmed diagnosis of moyamoya and a 6 mm basilar apex artery aneurysm (BAA). She underwent right sided craniotomy for direct and indirect revascularization by means of superficial temporal artery-middle cerebral artery (STA-MCA) bypass and encephalo-duro-arterio-synangiosis (EDAS)...

Limited data exist on clot composition and detailed characteristics of arterial thrombi associated with large vessel occlusion in acute ischemic stroke. Advances in endovascular thrombectomy and related imaging modalities have created a unique opportunity to analyze thrombi removed from cerebral arteries. Insights into thrombus composition, etiology, physical properties and neurovascular interactions may lead to future advancements in acute ischemic stroke treatment and improved clinical outcomes. Advances in imaging techniques may enhance clot characterization and inform therapeutic decision-making prior to treatment and reveal stroke etiology to guide secondary prevention...

Background The objective of ischemic stroke (IS) treatment is to achieve revascularization in cerebral arteries to restore blood flow. However, there is no available method to extract arterial flow data from clinical CTA images. We developed 3D Stroke Arterial Flow Estimation (SAFE), which provides blood flow data throughout the Circle of Willis based on 3D CTA and allows comparison of arterial flow distribution in the brain. Methods We implemented a newly developed 3D vascular reconstruction algorithm for clinical stroke CTA images...

BACKGROUND: The external carotid artery (ECA) is the main high-flow donor for extracranial-intracranial revascularization procedures. However, anatomic restraints limit the availability of ECA in posterior exposures of the craniocervical junction aimed for bypass to distal vertebral artery segments. OBJECTIVE: To examine the feasibility and safety of exposure of the ECA through the posterior triangle of the neck. METHODS: A preliminary feasibility study on the posterior neck exposure of the ECA was performed in 1 cadaveric head (2 sides) followed by a morphometric study on 9 cadaveric heads (18 sides)...

BACKGROUND: Posterior cerebral artery (PCA) aneurysms are rare and the majority are fusiform in shape. Proximal occlusion of PCA represents a treatment option for these lesions. However, this procedure carries a high risk of ischemic complications. OBJECTIVE: To describe the technique of trapping a fusiform PCA aneurysm and revascularization of the distal PCA using a superficial temporal artery (STA) graft through the same microsurgical approach. METHODS: From September 2012 to October 2014, we retrospectively identified 3 patients harboring a fusiform PCA aneurysm (P2 segment aneurysm) who underwent trapping of the aneurysm and reconstruction of the distal PCA through the same subtemporal approach...

BACKGROUND: Blunt traumatic aortic injury is the second leading cause of death in trauma patients age 4 to 34. Of the patients that are able to receive treatment, mortality rates as high as 40% have been reported. Endovascular repair options have allowed for more expeditious repairs with reduced iatrogenic trauma; however, when the injury involves the ascending aorta or arch, current endografts lack fenestrations needed for cerebral blood flow. Traditionally, on pump cardiopulmonary bypass with systemic anticoagulation has been used to repair these injuries...
