Detaillierte Beschreibung
Der ischämische Schlaganfall ist eine lebensbedrohliche Erkrankung. Jährlich erleiden etwa 795.000 Menschen in den Vereinigten Staaten einen Schlaganfall.
Die MARRS-Studie ist eine interventionelle, offene, einarmige, multizentrische, prospektive klinische Untersuchung. Ziel der Studie ist es, die Leistungs- und Sicherheitsmerkmale des Millipede-Systems bei Patienten mit akutem ischämischem Schlaganfall aufgrund von LVOs zu bewerten und die klinischen Ergebnisse aufzuzeichnen.

ITT Cohort: Rate of Core Lab-adjudicated Reperfusion Success Within Three Passes
Zeitfenster: Intraprocedural
|
Proportion of subjects with successful reperfusion, defined as achieving a modified Thrombolysis in Cerebrovascular Infarction (mTICI) score of 2b or greater within ≤3 passes with the Millipede System without additional therapy.
The mTICI scale ranges from 0 to 3, with higher scores indicating better reperfusion: 0 = no perfusion, 1 = minimal perfusion, 2a = partial (<50%), 2b = substantial (≥50%), 2c = near complete, 3 = complete.
This measure reports the number of participants who achieved mTICI ≥2b under these criteria as adjudicated by an independent Core Lab.
