Intervenção / Tratamento
Descrição detalhada
O AVC isquêmico é uma condição com risco de vida. Anualmente, aproximadamente 795.000 pessoas nos Estados Unidos sofrem um derrame.
O estudo MARRS é uma investigação clínica prospectiva, intervencionista, aberta, de braço único, multicêntrica. Os objetivos do estudo são avaliar as características de desempenho e segurança do Sistema Millipede em pacientes com AVC isquêmico agudo devido a LVOs e registrar os resultados clínicos.

ITT Cohort: Rate of Core Lab-adjudicated Reperfusion Success Within Three Passes
Prazo: 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.
