Aortic Endarterectomy for Aortic Occlusive Disease: An Old Operation With a Re-emerging Role

Introduction: Descending aortic complex atheromatous plaques can cause claudication, critical lower limb ischaemia (CLI), and are an independent risk factor for systemic embolization. Current practice involves dealing with most cases using endovascular techniques. However, open repair remains superior in terms of the patency rates and may be the only valid option in a subgroup of patients who are unsuitable for endovascular treatments. Most of the current data investigating open procedures are now historic. The aim of this study is to determine whether it is a feasible option in the current day practice. Patients and methods: Ten years data from 2010 to 2020 were collected retrospectively from the hospital records. Clinic letters, radiologic scans, operative records and discharge letters were reviewed. Death records were reviewed to identify patients who survived. Results: Ten cases were identified. The average age was 55 and the mean BMI was 29.4. The mean hospital stay in days was 12 (range: 4 to 22). The mean follow-up period was 147 days (range: 30 to 360 days). Four of the patients were TASC B, four were TASC C and two were TASC D. Two cases had to return to theatres. One patient had transient post-op AF and another had transient post-op ileus. One patient was readmitted within 30 days of discharge for urosepsis. All cases are alive to date except one case which only survived three years after procedure. Conclusion: AE is a procedure that should be considered in selected cases where endovascular approach is not feasible. There is a trend towards lower mortality than the historic data available in literature. Larger case series or registry data may be required to accurately estimate the current day mortality and morbidity figures.
