To estimate the incidence of cerebrovascular diseases in arteriosclerotic aortic aneurysm (AA) and arteriosclerosis obliterans (ASO) and their characteristics, 92 patients with AA and 102 patients with ASO were studied with carotid ultrasonography and brain computed tomography (CT), and were compared with 49 patients with hypertension. The mean ages of the patients were 70 to 72 years old and all were male. Hypertension was common in the AA group: diabetes and cigarette smoking were common in the ASO group. Carotid plaque lesions seen on ultrasonography were significantly more common in the AA (66%) and ASO (85%) groups than in the patients with hypertension (39%). The mean carotid diameter was significantly greater in the AA group than in the other two groups. The mean wall thicknesses in the AA and ASO groups were greater than in the patients with hypertension. Computed tomography showed that low-density areas were also common in the AA group (56%) and ASO (53%) groups than in the patients with hypertension (24%). Most of the low-density areas were thought to be lacunae or dilated perivascular spaces in the subinsula and putamen. Moderately and highly severe periventricular lucencies were also common in the AA group. These findings indicate that carotid changes, seen in AA and ASO, reflected the characteristics of arterial lesions, and that arteriolosclerotic lesions were common in patients with AA and ASO. Therefore, cerebrovascular diseases should be taken into account in the management of patients with AA and ASO.

UI	MeSH Term	Description	Entries
D006973	Hypertension	Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.	Blood Pressure, High,Blood Pressures, High,High Blood Pressure,High Blood Pressures
D008297	Male		Males
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D002339	Carotid Arteries	Either of the two principal arteries on both sides of the neck that supply blood to the head and neck; each divides into two branches, the internal carotid artery and the external carotid artery.	Arteries, Carotid,Artery, Carotid,Carotid Artery
D002561	Cerebrovascular Disorders	A spectrum of pathological conditions of impaired blood flow in the brain. They can involve vessels (ARTERIES or VEINS) in the CEREBRUM, the CEREBELLUM, and the BRAIN STEM. Major categories include INTRACRANIAL ARTERIOVENOUS MALFORMATIONS; BRAIN ISCHEMIA; CEREBRAL HEMORRHAGE; and others.

D001161	Arteriosclerosis	Thickening and loss of elasticity of the walls of ARTERIES of all sizes. There are many forms classified by the types of lesions and arteries involved, such as ATHEROSCLEROSIS with fatty lesions in the ARTERIAL INTIMA of medium and large muscular arteries.	Arterioscleroses
D001162	Arteriosclerosis Obliterans	Common occlusive arterial disease which is caused by ATHEROSCLEROSIS. It is characterized by lesions in the innermost layer (ARTERIAL INTIMA) of arteries including the AORTA and its branches to the extremities. Risk factors include smoking, HYPERLIPIDEMIA, and HYPERTENSION.	Obliterans, Arteriosclerosis
