Arteriectasis is a medical condition in which the walls of an artery become weak and dilated. There are several synonyms for arteriectasis, such as dilatation, dilation, and distension. Other related terms include aneurysm, saccular aneurysm, and fusiform aneurysm, which are all types of arterial dilatation. Arterial ectasia is another term used to describe this condition and it refers to the widening or ballooning of an artery. Arterial aneurysm is another synonym for arteriectasis, which is used to describe a bulging or ruptured area in an artery that can be life-threatening if left untreated. The condition can be diagnosed using imaging tests such as MRI, CT scan, or ultrasound. Treatment options may include medications, surgery, or other interventions depending on the severity of the condition.
