Introduction: Percutaneous transluminal angioplasty (PTA) has become an accepted technique in the treatment of aortoiliac occlusive disease, with success rates of 90-92%, and primary patency of 55-72% at 5 years. Aim: To evaluate the results of endovascular treatment (PTA or PTA with stents) of the aortoiliac sector. Material and Method: Descriptive, retrospective study (single-center case series) of patients, consecutively subjected to endovascular treatment (PTA or PTA with stents) of aortoiliac occlusive disease, during a period of 7 years (2002-2019), at the Dr. Eduardo Pereira Hospital in Val-paraíso, Chile. Results: 103 procedures were performed in 94 patients, male: 63.83%, female: 36.17%, mean age: 67.4 years (range 47-96), distribution of the lesions according to the TASC II classification: A (46.24%), B (39.78%), C (8.60%), D (5.38%), remodeling the aortic bifaction (kissing stent) in 6.80%, hybrid procedures (12.62%), average follow-up (47.13 months), clinical success (90.29%), technical success (94.17%), primary patency, assisted primary and secondary at 5 years of 68.09%, 75, 53% and 81.91% respectively, 5-year limb salvage rate of 84.04%, mortality < 30 days of 1.94%, 5-year survival of 90.42%. Discussion: Endovascular techniques in the aortoiliac sector are reliable, their technical results and patency are influenced by the clinical stage of the patient and the severity of the lesions treated. Conclusion: In appropriately selected patients, endovascular treatment of the aortoiliac sector, presents excellent results, allowing an increase in the indication for treatment in patients considered to be at high risk.
