Results and complications of endovascular neurointerventions in intracranial aneurysms and arteriovenous malformations, evaluated by conventional angiography and diffusion-perfusion MRI

Abstract: Aims - To describe and evaluate the efficacy and safety of intra-arterial fibrinolysis and the clinical outcome in SAH patients with thromboembolic complications during endovascular coiling of a ruptured aneurysm. (Paper I) - To describe the use and feasibility of magnetic resonance imaging (MRI), especially diffusion and perfusion imaging, in three patients treated endovascularly for various cerebrovascular disorders. (Paper II) - To evaluate treatment safety as well as complication frequency and management in endovascular coiling of ruptured and unruptured intracranial aneurysms using MR diffusion and perfusion imaging. (Paper III). - To evaluate treatment safety in patients with cerebral arteriovenous malformations and to correlate the anatomical results with regard to complications and clinical outcome using MRI, including diffusion-weighted (DWI) and perfusion imaging (PI). (Paper IV).
