BACKGROUND: According to the guidelines aortoiliac TASC D lesions should be treated by bypass. The purpose of this study was to examine the results of hybrid procedures with the use of a self-expanding covered heparin-bonded stent graft (Viabahn) in patients with extensive aorto-iliac lesions who were not considered to be suitable for open aorto-iliac surgery.
METHODS: All patients who received a hybrid procedure in combination with a Viabahn stent in our clinic to treat aortoiliac lesions between October 2011 and April 2017 were included in this retrospective analysis. Study endpoints were primary patency, amputation-free survival (AFS) and major adverse limb event (MALE) free survival after 2 years.
RESULTS: We included 23 hybrid procedures (endarterectomy of the common femoral artery or cross over bypass and aortoiliac stent) in 20 patients (median age 59 years). Indication was critical limb ischemia in 70.0%. The reasons why patients were on high risk for alternative open aortoiliac revascularization were hostile abdomen in 35.0%, cardiopulmonary contraindications in 35%, cancer in 10.0%, age >80 years in 10.0% and alcoholic cirrhosis in 10.0%. The 30-day mortality was 15.0%, the major amputation rate was 4.3%. We had no early graft occlusion. After 2 years primary patency was 100%, AFS 58.2% and MALE free survival 95.7%.
CONCLUSIONS: A hybrid procedure with the use of a Viabahn stent in severe aortoiliac pathologies showed good patency results in this selected patient group. Therefore, it should be considered a feasible alternative to aortoiliac bypass surgery in surgical high-risk patients.
