A comparison of dual-lumen balloon and simple microcatheters in the embolization of DAVFs and AVMs using onyx.

Endovascular embolization of arteriovenous malformations (AVMs) and dural arteriovenous fistulas (DAVFs) has become the mainstay in treatment for these pathologies. Traditional techniques required the formation of a proximal plug of Onyx around the microcatheter prior to embolization to avoid reflux. Recently, dual-lumen balloon catheters have been introduced as a potential solution to this issue.

Burr Hole-Assisted Direct Transsylvian Venous Catheterization for Carotid-Cavernous Fistula Embolization: A Case Report.

Background And Importance: Carotid-cavernous fistulas (CCF) are pathological connections between carotid artery branches and the cavernous sinus. They can lead to a variety of symptoms, such as chemosis and double vision, or more insidious events, such as vision loss and intracranial hemorrhage. Although these patients are often treated by endovascular means, we describe a case in which the patient's CCF was not able to be accessed by usual methods and required an open surgical approach.

Onyx Embolization of Spinal Arteriovenous Fistula via Scepter Balloon.

Background: Spinal arteriovenous fistulas (AVFs) are a rare entity that can have devastating neurologic outcomes. Currently, these lesions are treated via open microsurgical resection or transarterial embolization with good success. However, some patients cannot be treated with a minimally invasive endovascular technique secondary to difficulty catheterizing their vascular anatomy.

Bilateral Mechanical Thrombectomies for Simultaneous MCA Occlusions.

Background: Bilateral hemispheric dysfunction is devastating to consciousness. We present a unique case of a patient who developed bilateral middle cerebral artery infarcts with significant neurological improvement post bilateral thrombolysis in cerebral infarction (TICI) 3 thrombectomies.

Case Description: The patient is a 64-year-old woman who presented 3 hours after her husband was awakened and found her with left hemiplegia.

"Awake" clipping of cerebral aneurysms: report of initial series.

OBJECTIVE Risk of ischemia during aneurysm surgery is significantly related to temporary clipping time and final clipping that might incorporate a perforator. In this study, the authors attempted to assess the potential added benefit to patient outcomes of "awake" neurological testing when compared with standard neurophysiological testing performed under general anesthesia. The procedure is performed after the induction of conscious sedation, and for the neurological testing, the patient is fully awake.

Intractable vomiting caused by vertebral artery compressing the medulla: A case report.

Vertebral artery compressing the medulla and causing intractable vomiting has only been reported once previously. We report a case of a 69-year-old woman with intractable nausea and vomiting causing a 50 pound weight loss and who failed medical management and whose symptoms were completely reversed following microvascular decompression (MVD).

Management of nonmissile penetrating brain injuries: a description of three cases and review of the literature.

Nonmissile penetrating intracranial injuries are uncommon events in modern times. Most reported cases describe trajectories through the orbit, skull base foramina, or areas of thin bone such as the temporal squama. Patients who survive such injuries and come to medical attention often require foreign body removal.
