ABSTRACT
INTRODUCTION: To report total endovascular treatment for a rare case of Crawford extent IV thoraco-abdominal aortic aneurysm (TAAA) using custom-designed branched device in a patient with Behçet's disease. METHODS: A 50 years' old man with history of BD was accidentally diagnosed Crawford extent IV TAAA during computed tomography follow-up after left nephrectomy of renal carcinoma. The aneurysm extended from descending aorta to right common iliac artery with a maximum diameter of 6.2 cm. RESULTS: The endovascular procedure wassuccessfully performed using custom-designed branched component to cannulate visceral arteries, bifurcated endograft and iliac legs to exclude the aneurysm sac in abdominal aorta and an iliac branched device to preserve the right internal iliac artery. The patient was discharged without any complication. Computed tomography angiogram at one month after endovascular repair demonstrated total exclusion of the aneurysm, patent visceral branches and right internal iliac artery. No complication occurred to six-month follow-up. CONCLUSION: Endovascular treatment of stable TAAA in patients with Behc?et's disease using custom-designed branched device is feasible, microinvasive and safe. The long-term efficacy needs to be observed.
