Biomarkers of connective tissue disease in patients with intracranial aneurysms

Abstract

Connective tissue defects may play a significant role in the development of intracranial aneurysms (IAs). Multiorgan connective tissue disorders may, therefore, indicate a risk of IA development. We investigated biomarkers of connective tissue disease in patients with IAs. A series of 62 patients with IAs was studied by physical examination, echocardiography, ultrasound examination of the kidneys and abdomen, and microscopic examination of skin tissue (temporal area) and superficial temporal artery taken at operation. Patients with IAs had a higher incidence of biomarkers of systemic connective tissue disease than controls and identification of these markers may be important for screening for IAs. Microscopic investigation of biopsies of the skin and superficial temporal artery from patients and their relatives may become valuable for clinical diagnosis, identification of people at risk and basic studies of the pathogenesis of this vascular disease.
