Outcome of endovascular stroke therapy in a large mandatory stroke-registry.

Background: Endovascular stroke treatment (EST) has become the standard treatment for patients with stroke due to large vessel occlusion, especially in earlier time windows. Only few data from population-based registries on effectiveness of EST have been published.

Methods: Baden-Wuerttemberg is the third largest state in Germany in terms of area and population and has a structured stroke concept since 1998 which includes mandatory collection of quality assurance data.

Restriction of therapy mainly explains lower thrombolysis rates in reduced stroke service levels.

Objective: To assess the influence of preexisting disabilities, age, and stroke service level on standardized IV thrombolysis (IVT) rates in acute ischemic stroke (AIS).

Methods: We investigated standardized IVT rates in a retrospective registry-based study in 36,901 patients with AIS from the federal German state Baden-Wuerttemberg over a 5-year period. Patients admitted within 4.
