Anterior choroidal artery occlusions: Clinical and laboratory features

Abstract

OBJECTIVE: The anterior choroidal artery (ACHA) irrigation area, this area is very volatile infarction incidence and clinical characteristics of classical knowledge. In our study, patients with infarct lesion limited irrigation area of Achan was to determine the clinical and laboratory features.

METHODS: The patient group, magnetic resonance imaging, patients with lesions limited to the area by selecting Achan was created. In addition to the acute lesion Achan, the other in the sprawling grounds of the arteries of patients, additional lesions Those who define transient ischemic attack attributable to infarct Achan, the applicant passed before the first signs of neurological sequelae due to cerebrovascular disease and / or old lesions deemed capable of neurological deficits were excluded. Acha deciding that the irrigation area of the lesion, which is a deep dive irrigation area and medial thalamus, globus pallidus delimit the lateral thalamus formed the typical image of the lesion which were taken into account. For the superficial branch of the amygdala and hippocampus lentikülo-striate arteries occlusion seen in the posterior horn of the lateral ventricle of the lesion until komşuluğuna taken into account.

RESULTS: A statistically significant difference in hypertension common modifiable risk factor for the highest rate (p <0.000). Pure motor or sensory examination in all patients except 1 patient showed signs of stroke. According to the classification of etiologic TOAST small vessel disease, significantly higher rate compared to other etiologies (p <0.000). Etiologic groups compared to the risk factors of hypertension and hyperlipidemia in patients with small vessel disease, atrial firillasyon (AF) kardioemboli group was significantly higher (p = 0.035 and p = 0.011, p = 0.005). Introduction of the patients were between NIHSS 1-15 (6 + 3.2). Between mRS 0-4 at baseline (1.83 +1.22). Infarct area, Acha is one of the branches or the entire irrigation area, both risk factors did not differ in terms of both the etiology and prognosis.

CONCLUSION: Achan irrigation area of ischemic lesions, MR imaging methods can be recognized. Localization of ischemic lesions typical for Achan, risk factors, etiology and prognosis in patient groups with similar characteristics are homogeneous. Recognition of these lesions, it is important to determine the prognosis and treatment.
