Interventional stroke treatment - Is it also safe for arteries? Looking at thrombectomy wall damage through clot histology.

ABSTRACT:

Background and purpose

The aim of this study was to investigate whether morphological evidence of intracranial vascular injury can be found in the occluding thrombi of patients with ischemic stroke.

Methods

From 2015 until 2018 specimens of thrombi from patients with large vessel occlusion treated either by stent-assisted aspiration thrombectomy (TE) or by aspiration thrombectomy were prospectively collected. Thrombus specimens were formalin-fixed, paraffin-embedded and stained. Architectural features, presence of parts of vessel wall or atheromatous material, organisation of the thrombi, technique and number of thrombectomy manoeuvers were evaluated.

Results

Thrombus specimens from 302 patients were analyzed. 238 (80%) patients were treated with stent-assisted aspira
