Abstract WP14: Where Should We Direct Our Efforts Among A Few In-hospital Steps From ER Arrival To Achieve Faster Recanalization In Acute Ischemic Stroke?
[Back ground and purpose] Faster recanalization is related to better clinical outcome in acute ischemic stroke. The purpose of our retrospective study is to analyze the time taken in various aspects of in-hospital care from ER arrival to arterial puncture in patients undergoing endovascular therapy and to find which step the longest is.
[Method] Stroke Center Database was investigated retrospectively and included in our analysis were patients (1) who were admitted to our institution from January 2004 to June 2012, (2) who presented some neurological symptoms, (3) who underwent MRI following CT, which showed acute ischemic stroke caused by major vessel occlusion and no intracerebral hemorrhage, (4) who underwent endovascular therapy including local intra-arterial fibrinolysis, mechanical thrombectomy using balloon, Merci retrieval system and Penumbra system and stenting. We examined the times from ER arrival to arterial puncture (ER-AP), from ER arrival to CT ( ER-CT ), from CT to MRI ( CT-MR ), and from MRI to arterial puncture ( MR-AP).
[Result] During the study period, 201 patients were included for retrospective analysis. The average ER-AP time was 177 minutes ( 49 - 455 minutes), the average ER-CT, CT-MR and MR-AP times were 29 minutes ( 0 - 197), 58 minutes ( 6 - 300) and 90 minutes ( 10 - 349), respectively. The MR to AP step spent the longest time and the CT to MR step was the second.
[Conclusion] CT to MR and MR to arterial puncture times show wide variability and the times must be reduced to achieve faster recanalization by endovascular therapy.
