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.

PTA and stenting after previous aortoiliac endarterectomy

OBJECTIVES

to evaluate the feasibility and long-term results of angioplasty and stenting in the treatment of restenosis following aortoiliac endarterectomy.

MATERIALS AND METHODS

between 1991 and 1999 19 patients underwent angioplasty with selective stenting for recurrent stenosis after previous aortoiliac endarterectomy. Aortic lesions were treated five times in four patients. At the iliac level 28 lesions (25 stenosis and three occlusions) were treated in 16 patients (one patient had a stenosis at the aortic as well as iliac level). All patients were followed clinically and by ultrasound. In the second half of 1999, an angiogram or spiral CT-angiography was performed in all patients to determine long-term outcome.

RESULTS

technical success was obtained in all patients and clinical success was achieved in 18 of the 19 patients. Angiographic cumulative primary patency for aortoiliac lesions was 96% at 1 year and 76% at 3 years.

CONCLUSIONS

angioplasty with selective stenting of recurrent aortoiliac disease after previous aortoiliac endarterectomy is feasible and safe. Long-term clinical and angiographic patency rates are in accordance with results of aortoiliac angioplasty in general.
