Relation of Common Carotid Artery Lumen Diameter to General Arterial Dilating Diathesis and Abdominal Aortic Aneurysms: The Tromsø Study

摘要

In a cross-sectional, population-based study in Tromsø, Norway, the authors investigated correlations betweennlumen diameter in the right common carotid artery (CCA) and the diameters of the femoral artery and abdominalnaorta and whether CCA lumen diameter was a risk factor for abdominal aortic aneurysm (AAA). Ultrasonographynwas performed in 6,400 men and women aged 25–84 years during 1994–1995. An AAA was considered present ifnthe aortic diameter at the level of renal arteries was greater than or equal to 35 mm, the infrarenal aortic diameternwas greater than or equal to 5 mm larger than the diameter of the level of renal arteries, or a localized dilation of thenaorta was present. CCA lumen diameter was positively correlated with abdominal aortic diameter (r ¼ 0.3, P
