Economic and Efficient: Introducing the Bifurcation-Invisible Sign in Endovascular Thrombectomy for Middle Cerebral Artery Occlusions.

Introduction: Selecting thrombectomy techniques for acute ischemic stroke due to large vessel occlusion significantly affects outcomes and costs. This study introduces the Bifurcation-Invisible (BI) sign identified on initial microcatheter angiogram in acute middle cerebral artery occlusions before endovascular thrombectomy. We aimed to evaluate whether this sign is associated with better angiographic outcomes using contact aspiration (CA) versus stent retriever (SR).

Clinical application of optical coherence tomography angiography in diabetic macular edema.

Diabetic macular edema (DME) is characterized by a retinal thickening or hard exudation deposition in the fundus microvasculature, capillary leakage, increased vascular permeability, extracellular fluid accumulation in the fovea of a foveal disc.
