LOS ANGELES – Evidence continues to mount that in the new era of thrombectomy treatment for selected acute ischemic stroke patients outcomes are better when patients go directly to the closest comprehensive stroke center that offers intravascular procedures rather than first being taken to a closer hospital and then needing transfer.
, presented a modeled analysis of data collected in a registry on 236 real-world U.S. patients who underwent mechanical thrombectomy for an acute, large-vessel occlusion stroke following transfer from a hospital that could perform thrombolysis but couldn’t offer thrombectomy. The analysis showed that if the patients had instead gone directly to the closest thrombectomy center the result would have been a 16-percentage-point increase in patients with a modified Rankin Scale (mRS) score of 0-1 after 90 days, and a 9-percentage-point increase in mRS 0-2 outcomes, Dr. Mueller-Kronast said at the International Stroke Conference, sponsored by the American Heart Association.
Theused data from the Systematic Evaluation of Patients Treated With Stroke Devices for Acute Ischemic Stroke ( ) registry, which included 984 acute ischemic stroke patients who underwent mechanical thrombectomy at any one of 55 participating U.S. sites ( ). A previously-reported analysis of the STRATIS data showed that the 55% of patients taken directly to a center that performed thrombectomy had a 60% rate of mRS score 0-2 after 90 days, compared with 52% of patients taken first to a hospital unable to perform thrombectomy and then transferred ( ).
