Feasibility and Safety of Double-wire Technique for Microcatheter Navigation Beyond Tortuous Internal Carotid Siphon: a Propensity Score Matched Study.

Background: Severe vessel tortuosity may prevent a microcatheter from reaching a distal vessel. However, the Double-Wire Technique (DWT) may facilitate the procedure. The present study evaluated the feasibility and safety of guiding a 0.

Visual impairment associated with direct compression of the visual cortex due to subdural hematoma following foramen magnum decompression: illustrative case.

Background: Postoperative subdural hematoma (SDH) typically presents with headache, impaired consciousness, hemiplegia, gait disturbance, and aphasia but can also present with visual impairment.

Observations: A 52-year-old woman diagnosed with Chiari malformation type I and syringomyelia underwent foramen magnum decompression. Cerebrospinal fluid was lost due to arachnoid injury during the procedure.

Mechanism and management of acute femoral artery occlusion caused by suture-mediated vascular closure device following neurointervention.

Vascular closure devices (VCDs) show fewer complications related to the puncture site than manual compression but can cause stenosis or occlusion of the common femoral artery (CFA). A patient in her 30s who underwent suture-mediated VCD for haemostasis at the right CFA puncture site after neurointervention showed occlusion of the right CFA on postoperative day 2. Endovascular treatment retrieved the thrombus from the occlusion site, and surgical removal of a suture causing stenosis between the dissected posterior wall intima and anterior wall allowed the resumption of full flow through the right CFA.
