Abstract

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. Material and Method: 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. he 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 iseae in one patient and chronic renal failure in one patient. Result: 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.

배경: 고위험환자에서 대동맥 수술은 사망률 및 합병증 발생률이 높으며, 악성종양이 동반된 환자에서는 기대여명이 짧으므로 대동맥 수술의 필요성에 대해 의문을 가질 수 있다. 대동맥내 스텐트 그라프트의 삽입은 대동맥 수술에 비해 침습도가 떨어지며, 회복기간이 짧아 고위험 환자 및 악성종양 환자에게 고려될 수 있다. 특히, 경피적으로 삽입 가능한 스텐트 그라프트는 전신마취의 필요성이 없어 고위험 환자에서 더 유용하게 사용될 수 있다. 대상 및 방법: 2003년 7월부터 2007년 9월까지 근치적 절제술이 불가능한 악성종양을 가진 환자 또는 동반질환으로 인해 대동맥 수술시 합병증 발생의 위험도가 높은 12명의 환자에서 경피적으로 대동맥 스텐트 그라프트의 삽입이 시행되었다. 삽입의 적응증이 된 대동맥 질환은 복부대동맥류가 5례, 흉부대동맥류가 6례, 급성대동맥 박리증이 1례이었다. 동반질환으로 악성종양이 3례, 호흡기 질환이 6례, 고령 및 신경계 질환이 6례, 베체트 병이 1례, 만성 신부전증이 1례이었다. 결과: 전례에서 경피적으로 스텐트 그라프트의 삽입이 가능하였다. 이 중 4례에서 원내사망이 있었고, 추적관찰 기간 중 3례의 만기사망이 있었다. 원내사망 1례를 제외하고는 대동맥 질환으로 인한 사망은 없었다. 합병증으로는 경도의 뇌졸중이 1례가 발생하였으며, 급성 신부전증 및 허혈성 장괴사가 각각 2 및 1례에서 발생하였다. 그라프트 주위유출 (endoleak)은 스텐트 그라프트 삽입 직후 2명에서 경도의 1형의 주위유출이 관찰되었고, 2형 그라프트 주위유출이 1명에서 발견되었다. 외래추적기간 중 1명에서 새로운 1형의 그라프트 주위유출이 발생하였다. 결론: 고위험 환자 및 기대여명이 짧은 악성종양 환자의 대동맥 질환에서 경피적 스텐트 그라프트의 사용은 비교적 안전한 방법으로 고려해 볼만한 치료법이나, 아직 적응증이나 장기성적에 대해서는 더 논의가 필요할 것으로 생각된다.
