Therapeutic description of common iliac artery aneurysms. Number of cases

Abstract

Common iliac artery aneurysms (CAIA) are rare. The main etiology is atherosclerosis, while other reports include origins as diverse as pregnancy, infection, and iatrogenic trauma. We present a series of cases of common iliac aneurysm with risk of imminent rupture. We show the therapeutic approach through the open or endovascular surgery technique, obtaining good results. Of the patients admitted with the diagnosis of common iliac artery aneurysm, a review of the cases operated on in the angiology service was carried out on January 1, 2018 and April 30, 2022. An analysis of three patients is presented on the etiologies, the diagnosis and treatment. Three patients with the presence of AAIC treated in the service were identified, of which 2 males and 1 female, average age 50 years, smoking was present in 66% of the cases, open surgical treatment 1 case due to complex anatomy and 2 Endovascular technique. The discharge was earlier with the Endovascular therapy with less hospital time, although in one case Endovascular presented arterial rupture, in the 3 cases the closure of the aneurysmal sac was achieved without complications at discharge with good evolution. AAIC are present in a very low percentage, which is why they should be sought in patients with a history of smoking, abdominal trauma, and atherosclerosis. The diagnostic method of choice to define the anatomical characteristics is CT angiography with reconstruction 3, which helps us determine the diameter and extension of the aneurysm to plan the best treatment, as well as its relationship with important structures of the pelvic cavity that must be considered, such as the artery external iliac (hypogastric), colon and ureter. They must be treated because rupture is associated with high mortality, proper planning determines the success of treatment.
