Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to compare time delay and safety parameters of stroke patients initially admitted to a rural primary stroke center (PSC) who receive endovascular treatment (EVT) by a Flying Intervention Team with patients who receive EVT after secondary transfer to a comprehensive stroke center (CSC).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A novel health care concept was implemented in the telemedical stroke network TEMPiS (Telemedical Project for integrative Stroke Care) to reduce time delays to EVT in stroke patients with large vessel occlusion: After telemedicine-assisted identification of EVT candidates in a PSC, a Flying Intervention Team (neuroradiologist and angiography assistant) is flown from a CSC via helicopter to the PSC to perform EVT in the local angiography suite. Flying Intervention Team service runs from 8 a.m. to 10 p.m. Patients remain at local stroke unit for further treatment.

Analysis will include time delay to EVT, recanalization, symptomatic intracerebral hemorrhage, periprocedural complications, in-hospital complications, and mortality.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

EVT by Flying Intervention Team in primary stroke center

Patients with ischemic stroke and large vessel occlusion admitted to a primary stroke center, for whom a Flying Intervention Team is flown to the primary stroke center in order to perform endovascular treatment.

Endovascular treatment by Flying Intervention Team

Intervention Type OTHER

After telemedicine-assisted decision for endovascular treatment, the Flying Intervention Team is transferred via helicopter to the primary stroke center and performs endovascular treatment in the local angiography suite.

EVT after secondary transfer to comprehensive stroke center

Patients with ischemic stroke and large vessel occlusion admitted to a primary stroke center, who are transferred to a comprehensive stroke center for endovascular treatment.
