Background : Aortic surgery for high risk patients has high mortality and morbidity rates, and the necessity of performing aortic surgery in cancer patients is questionable because of their short life expectancy. Endovascular repair of aneurysm repair can be considered for high risk patients and cancer patients because it has relatively lower invasiveness and shorter recovery times than aortic surgery does. Especially, percutaneous endovascular stent graft treatment is more useful for high risk patients because it does not require general anesthesia.
Materials & Methods : From July 2003 to September 2007, twelve patients who had inoperable malignancy or who had a high risk of complication because of their combined diseases during aortic surgery underwent endovascular aortic aneurysm repair. The indications for endovascular repair were abdominal aortic aneurysm in 5 patients, descending thoracic aortic aneurysm in 6 patients and acute type B aortic dissection in one patient. The underlying combined disease of these patients were malignancy in 3 patients, respiratory disease in 6 patients, old age with neurologic disease in 6 patients, Behcet’s diseae in one patient and chronic renal failure in one patient.
Results : Stent grafts were inserted percutaneously in all cases. There were 4 hospital deaths and there were 3 delayed deaths during the follow-up periods. There were no deaths from aortic disease, except one hospital death. There were several complications: a mild cerebrovascular accident occurred in one patient, acute renal failure occurred in 2 patients and ischemic bowel necrosis occurred in one patient. Mild type I endoleak was observed in 2 patients and type II endoleak was observed in a patient after stent graft implantation. Newly developed type I endoleak was observed in a patient during the follow-up period.
Conclusion : Percutaneous endovascular stent graft insertion is relatively safe procedure for high risk patients and cancer patients. Yet it seems that its indications and its long term results need to be further researched.
