Neurointervention offers minimally invasive therapies for a wide variety of neurovascular diseases. Over the years it has evolved and established itself as a preferred modality of treatment over conventional open surgical approach. The adoption of endovascular therapy for the management of aneurysms, acute stroke, vascular malformations, and presurgical, or palliative embolization has expanded over the last three decades. This trend is likely to amplify further with the introduction of innovative endovascular devices. Neurointervention spans various specialties, namely: neurosurgery, neuroradiology, neurology, and cardiology. Accordingly, it has embraced many names such as endovascular neurosurgery, interventional neuroradiology, and interventional neurology. This book has 5 chapters, including:Chapter I, Imaging techniques in Acute ischemic Stroke; Chapter II, Neurosurgical treatment for hemorrhagic and ischemic stroke; Chapter III, Endovascular intervention in the management of Ischemic stroke; Chapter IV, Direct Aspiration thrombectomy for acute stroke; Chapter V, Mechanical thrombectomy and stenting for stroke; and References.
