أشكال النشبات الدماغية الإقفارية و عوامل الخطورة فيها

Abstract EN

Background &Objective: This study aims to classify ischemic strokes into its major subtypes, and discover the mains risk factors involved.

Methods & Material: a prospective study was done on 200 patients admitted to the neurology department, as well as the emergency room, at Alassad University Hospital in Damascus, Syria, between January 2012 and January 20014.

Each patient was diagnosed with cerebral infarct, using CAT scan or MRI of the brain.

We also ran hematologic, cardiac, and vascular study for each patient and we classify each case according to TOAST classification .Moreover we study the risk factors in each subtype and compare the results with medical literature.

Results: we classified each case according to (ToAst) classification, and we study the risk factors in each group.

The results were divided in to: 1.

Infarcts of the large arteries (29.9%).

2.

Infarcts of cardio-embolic (14.5%).

3.

Infarcts of the small arteries (49.5%).

4.

Infarcts of undetermined etiology (0.9%).

5.

Infarcts of determined etiology (5.1%).

Hypertension and hyperlipidemia continues to be the major cause of small vessel disease in our country.

Carotid stenosis is the most important risk factor in infarcts of the large arteries.

AF is the most important risk factor in cardio embolic strokes.

Conclusion: In our country, the infarcts of small vessel disease are more frequent, and then the infarcts of the large arteries, and then the infarcts of cardio embolic strokes.

The most important factor, in the formation of the Infarcts of the small arteries, is not hypertension only but hyperlipidemia play the same role.
