PRESENTATIONS AND OUTCOMES OF AORTOFEMORAL BYPASS GRAFTING

Objectives: The aim of the study is to study presentations and clinical outcomes in patients undergoing Aortofemoral Bypass Grafting Surgery (AFB). Design: This was a Hospital based prospective study. Materials And Methods: During 18 months period , 20 patients (mean age = 56 years) underwent AFB. Indications comprised of occlusive disease with Intermittent Claudication (IC) (n=10), Critical Limb Ischaemia (CLI)(n=4), Resting Pain (RP) (n=4) and Tissue Loss (TL) (n=2). Results: From Jan 2023 to June 2024, AFB was performed more frequently for IC (50%) vs rest of other indications. 30 day observations / follow up showed infection in 5%, Graft occlusion in 5% for which patient underwent emergency graft thrombectomy, Amputation in 10% due to gangrenous changes and 15% mortality. Graft patency was found to be triphasic in 90% cases. Hypertension was leading risk factor (85%) followed by Diabetes Mellitus(70%) and smoking (65%). Predictors of morbidity included CKD (25%), CAD (25%), COPD (20%), CVA (20%).90% Patients were operated via thoracotomy approach and 10% were operated via abdominal approach depending on level of aortic thrombus. 20% of patients had previous history of endovascular interventions followed by stent occlusion. Conclusion: In era of endovascular intervention, Aortofemoral Bypass Surgery is more likely to be performed for Intermittent Claudication and graft patency has a better outcome.
