Outcomes After Thrombectomy for Primary and Secondary Medium Vessel MCA Occlusions: a Nationwide Registry Study.

ABSTRACT:

Background

Medium vessel occlusions (MeVO) can be either isolated events (primary), or secondary to thrombus migration from a large vessel occlusion to a medium-sized vessel. Outcomes following endovascular thrombectomy (EVT) in the middle cerebral artery (MCA) may differ between primary and secondary MeVOs. This study aimed to assess the association between primary/secondary MeVOs and clinical outcomes following EVT in a nationwide patient cohort.

Method

Patients undergoing EVT were included in two Swedish quality registries. Secondary MeVO was defined as distal migration of a solitary thrombus between baseline CT-angiography and EVT, or basal ganglia infarction on postoperative CT in a patient that presented with a single MeVO on baseline CT-angiography. The primary outcom
