Pathogenesis of leukoaraiosis (LA) is not clearly understood and its significance in patients with stroke remains undetermined. In the Neurology Department of Ankara Hospital, computed tomography (CT) examination of brain was performed for various reasons in 288 patients. LA was detected in 178 patients by the use of brain CT. Patients with LA had a higher incidence of hypertension history (70.8%) when compared with the non-LA group (57.3%; p <.05). There was no statistically significant difference in terms of sex, mean age, smoking, diabetes mellitus, history of cerebrovascular disease, cardiac failure, ischemic cardiac disease between patients with and without LA. We showed that LA is related to hypertension but not related to age, diabetes mellitus, or cardiac disease in our patient population.

The frequency of venous reflux was nearly identical across GSV types. The frequency of segmental aplasia was similar in patients with and without reflux. Despite these similarities, defining GSV type and identifying segmental aplasia can provide guidance for treatment. In particular, type D GSVs, defined by the presence of an anterior accessory branch, should be investigated when performing CDUS. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 45:332-336, 2017.
