Abstract
Background
Brain ischemia may affect hypothalamic-pituitary axis function, which may influence the outcomes of patients with internal carotid artery (ICA) stenosis/occlusion. The objective of this study was to determine the influence of successful carotid revascularization on pituitary function in patients with severe ICA stenosis/occlusion.
Methods
This study was conducted from April 2009 to December 2014. Patients receiving successful endovascular interventions for severe ICA stenosis/occlusion were enrolled. The patients were divided into 2 groups: group 1 with abnormal ipsilateral cerebral perfusion, and group 2 without. Endocrine profiles were measured before and > 1 year after the procedure. Computed tomography perfusion studies were used to assess brain perfusion.
Results
Thirty-seven patients received successful interventions. Three patients were excluded due to re-stenosis before 1 year. There were 23 and 11 patients in group 1 and 2, with mean ages of 68 and 69 years, respectively. In the female patients, follicular stimulating hormone (FSH) and luteinizing hormone (LH) increased significantly (p = 0.043) after the interventions with a stable estradiol level in group 1. In contrast, FSH, LH and estradiol showed a decreasing trend in group 2. In the male patients, FSH and LH increased significantly (p < 0.01) after the interventions with a stable testosterone level in group 1, while testosterone showed a decreasing trend in group 2. Thyroid stimulating hormone increased significantly in the women in both groups, and in the men in group 1.
Conclusions
Successful revascularization for severe ICA stenosis/occlusion may improve their pituitary function, especially FSH and LH levels.
