What term describes dilation of a vessel without forming an aneurysm?

Explanation:
Dilation of a vessel without forming a sac is described as ectasia. An aneurysm, in contrast, is a localized outpouching with wall thinning that creates a sac and carries a rupture risk. A varix refers to a dilated, often tortuous vein, typically venous rather than arterial. Dilation is a broad term for widening without specifying pattern or risk. Therefore, when a vessel is widened but does not develop a focal sac, ectasia is the most precise term.
