Patients with “M2” middle cerebral artery occlusion pose a decision-making challenge currently as there are limited trial data and the patients in trials likely represent the larger vessel and more clinically severe end of the spectrum. 3. the relation of the teeth of both jaws when in functional contact during activity of the mandible. However, the outcomes of MT for M2 occlusion have not been well characterized. We aimed to assess outcomes in stroke patients treated with different endovascular procedures versus direct MT alone for isolated M2-MCA occlusion. What does preocclusion mean?

Rebar microcatheter was placed in the RIGHT MCA M2 segment. Define occlusions. One issue that is important in any study that examines MT for M2 occlusion is a clear description of the definition of an M2 branch. An M3 partial branch occlusion of the right superior division, especially with collateralization, is unlikely to result in major deficits and the risk/benefit may not favor aggressive intervention. anon m2 vs m3. The original classification by Fischer in 1938 18 designated the M1 segment as terminating at the genu where the MCA takes a 90° upward turn around the limen insulae; this definition was used in the STAR, SWIFT, and SWIFT PRIME studies. The aim of our study was to prove the efficacy and safety of mechanical thrombectomy for distal occlusion types in the anterior circulation (M2-segment). In a subgroup analysis, we found that among patients with hypertension, mechanical thrombectomy achieved better functional outcomes and recanalization in M2 occlusion than M1 occlusion. Fluid and blood will then leak from the blood vessels into the delicate tissue of the retina, forcing its layers apart and affecting its ability to respond to light.

CONCLUSION: Mechanical thrombectomy performed with second-generation thrombectomy devices for M2 occlusion can provide a good functional outcome as well as satisfying recanalization.
