Thrombectomy for medium-sized cerebral vessel occlusion: Size does matter.

ABSTRACT:

Introduction

Randomised controlled trials comparing endovascular thrombectomy (EVT) to medical treatment in patients with medium vessel occlusion (MeVO) suggested neutrality or futility of EVT. We studied whether the size difference between thrombectomy device and the occluded vessel influenced MeVO outcomes.

Patients and methods

This was a retrospective single-centre observational study comprising EVT-treated patients with occlusion of the M2 branch of the middle cerebral artery on digital subtraction angiography. The diameter of the occluded M2 was measured and compared to the manufacturer's recommendation for the minimal vessel size. Based on this device-to-vessel size ratio, we divided the patients into three groups: A) ratio ⩽1.0 (device smaller or equals the vessel siz
