Vascular Interventions and Surgical Experience

Visceral and iliac aneurysms are relatively rare yet potentially catastrophic when rupturing. Although most visceral and iliac aneurysms are degenerative, they can also be encountered in the setting of connective tissue disorders, such as Loeys-Dietz syndrome and vascular-type Ehlers-Danlos syndrome. Aneurysms-Osteoarthritis syndrome (AOS) is also known to be associated with aneurysms and arterial tortuosity in large and medium-size vessels throughout the arterial tree. As described in Chapter 2, one-third of AOS patients had aneurysms in other thoracic or abdominal arteries, predominantly involving the pulmonary, splenic, iliac, and mesenteric arteries. This subchapter discuss endovascular and surgical treatment options and their results for patients with visceral and iliac aneurysms associated with AOS.
