Highlights

The atherosclerotic stenotic disease forms an important cause of secondary prevention of stroke
Between January 2016 to March 2019, 224 cerebral digital subtraction angiography (DSA) was performed in the patients referred to us in university medical college, who had small or large vessel disease diagnosed by Doppler, CTA, or magnetic resonance angiography (MRA)
All patients with symptoms or signs of an ischemic stroke related to atherosclerosis who were referred to our department for cerebral angiography during the study interval were included in this study

Summary

Introduction

The atherosclerotic stenotic disease forms an important cause of secondary prevention of stroke. 12 In a study by magnetic resonance angiography (MRA) in Taiwan Chinese, approximately 24% of patients had the only extracranial carotid disease, and about 26% had only intracranial carotid artery disease. This study analyses retrospectively and prospectively angiographic data in ischemic stroke patients referred to our center, which is a territory care hospital, These patients had evidence of large or small vessel disease on Doppler, CT angiography, MRA and cerebral angiography. With the advent of endovascular technique, it is becoming possible to modify intracranial stenotic lesions by stent angioplasty with reasonable safety This may open up a new dimension in secondary prevention of stroke. This study analyses retrospectively and prospectively angiographic data in ischemic stroke patients referred to our center, which is a territory care hospital. The reason for relatively higher incidence could be shared geographical region (Asia) in concordance with Chinese and Korean studies but relatively lower incidence from this population may be due to different prevalence of risk factors in this population
