Summary

The MEMENTO (MEchanical thrMobectomy NETwork for MENA TOgether) Registry is a multicenter, prospective observational study aiming to evaluate the effectiveness, safety, and cost-effectiveness of mechanical thrombectomy (MT) in patients with acute ischemic stroke (AIS) due to large vessel occlusions (LVO) in the Middle East and North Africa (MENA) region. This interim analysis reports on the first 499 patients enrolled, assessing clinical outcomes, procedural details, and economic implications.

Detailed description

Detailed Description Stroke is a leading cause of morbidity and mortality worldwide, with a significant burden in the MENA region due to limited access to advanced stroke care therapies like mechanical thrombectomy (MT). The MEMENTO Registry seeks to collect real-world data on MT practices, outcomes, and accessibility in the MENA region to inform clinical practice and policy. The study includes AIS patients who underwent MT for confirmed LVO or medium vessel occlusion (MeVO), with or without prior intravenous thrombolysis (IV tPA), regardless of age, baseline NIHSS score, or time from symptom onset. Data collected encompass demographics, clinical characteristics, imaging findings, procedural details, outcomes at discharge and follow-up, complications, and a cost-effectiveness analysis comparing MT to standard medical care (SMC). The primary outcome is functional independence at 90 days post-procedure, defined as a modified Rankin Scale (mRS) score of 0-2.
