Clarification of embolic source in ischaemic stroke by non-obstructive general angioscopy.

ABSTRACT:

Background

Aortogenic stroke is an important subtype of embolic strokes, yet lacks a diagnostic method for proactive identification. Non-obstructive general angioscopy (NOGA) is a catheter-based technique to observe spontaneously ruptured aortic plaques (SRAPs), a potential embolic source of ischaemic stroke.

Objectives

This study aimed to identify the embolic source of ischaemic stroke using NOGA.

Methods

From June 2022 to January 2024, 321 consecutive patients with acute ischaemic stroke were hospitalised. 25 underwent emergent mechanical thrombectomy and NOGA. The aortic arch was screened using NOGA, and atherosclerotic materials from the SRAPs were sampled and pathologically analysed. Transoesophageal echocardiography (TEE) was performed the day after catheterisat
