Endovascular Repair of an Abdominal Aortic Aneurysm with Iliac Vein Compression Syndrome

抄録

An 84-year-old man with chronic obstructive pulmonary disease (COPD) was referred to our institution for further treatment of severe swelling of the left lower extremity. The left iliac vein was compressed by the abdominal aortic aneurysm and a right common iliac arterial aneurysm measuring 62 mm and 45 mm in diameter and was partially thrombosed. Multiple pulmonary artery embolisms were also noted. Endovascular repair of the abdominal aortic aneurysm and the right common iliac arterial aneurysm was performed because of his respiratory dysfunction. The left leg edema gradually resolved after endovascular treatment. Six months after the treatment, computed tomography (CT) demonstrated resolution of the venous thrombus of the left lower extremity. Although open surgery is reliable treatment for iliac compression syndrome, endovascular treatment might be a feasible and an adequate therapeutic option for patients who have severe comorbidities, complications, or high frailties.
