THE OUTCOMES OF ENDOVASCULAR INTERVENTION FOR AORTOPIC ARTERY STENOSIS AND LOWER LIMBS IN ELDERLY PATIENTS
Main Article Content
Abstract
Background: Atherosclerosis is a common disease in the elderly. Among them, the dangerous complication is aortic stenosis and occlusion of the lower limbs. Recently, treatment by endovascular intervention has been deployed, but there is little information about the results of its application in elderly patients. Subjects and Methods: A cross-sectional study described the characteristics of elderly patients with aortoiliac and lower limb arterial stenosis or occlusion and the outcomes of endovascular interventions from 01/2023 to 06/2024 at Thong Nhat Hospital. Results: The study collected data from 77 patients, with 72.8% male and 27.2% female. The mean age was 68.3 ± 11.7 years. Risk factors included dyslipidemia in 45.4%, hypertension in 41.5%. Vascular lesions were located in a single anatomical level in 63.6% and in multiple levels in 36.3%. Clinical symptoms included rest pain (Rutherford grade V) in 35.1% and tissue loss in 32.5%. The ankle-brachial index ranged from 0.5 to 0.9 in 67.5% of patients. The duration of endovascular intervention was 159.2 ± 29.3 minutes; the hospitalization was 4.3 ± 2.6 days. The primary revascularization rate was 92.2%, and the clinical symptom improvement rate was 90.9%. The pre-intervention ABI was 0.51 ± 0.13, which increased to 0.78 ± 0.14 after the procedure (p = 0.004). Complications included one case of common iliac artery perforation requiring open surgery and two cases of stent occlusion. Conclusion: The primary patency success was 92.2%, the treatment process had some complications but the rate was low. Treatment of aortic iliac stenosis and lower limb stenosis by endovascular intervention can be applied to elderly patients with high risk.
