Research Focus


Area of Research

Acute ischemic stroke, in particular the interventional treatment of medium vessel occlusions and workflow approaches to optimize patient outcomes
Hemorrhagic stroke, new interventional approaches for the treatment of intracranial aneurysms and arteriovenous malformations

Approved Research Projects

DISTAL Study: (EnDovascular therapy plus best medical treatment (BMT) versus BMT alone for MedIum VeSsel Occlusion sTroke - a prAgmatic, international, multicentre, randomized trial): Randomized, SNF funded study to investigate the efficacy of mechanical thrombectomy in medium vessel occlusion stroke patients

SPINNERS Study: ProSPective evaluation of the dIagnostic accuracy of siNe spiN non-contrast flat-dEtectoR CT (FDCT) for the detection of intracranial hemorrhage in Stroke patients - an open labelled, multicenter, non-inferiority comparison to multi detector CT (MDCT) with blinded assessment of outcome events

HemEXPLO Study: Detection of an endovascular treatment target in patients with an acute, spontaneous intracerebral Hemorrhage – an EXPLOrative pilot study
