Aortitis is one of the manifestations of giant cell arteritis (GCA) and is included in its definition. There is a significantly increased risk of aortic aneurysm formation in GCA patients. In some GCA patients aortic aneurysm dissection is diagnosed only in autopsy. Monitoring of these patients, especially in long lasting disease, requires a doctor's awareness of the possibility of aneurysm formation and aortic aneurysm dissection. Based on the available reports it cannot be confirmed whether intensification of aortitis treatment in GCA prevents the development of aneurysms. This article presents an overview of the available literature and our own experience on a rational diagnosis of inflammation and aneurysms of the aorta in GCA, as well as the prospects for its prevention.
