It is known that abstinence of smoking is the most effective treatment for Buerger s disease and surgical treatment is not frequently done because its result is not as good as that for atherosclerosis. We performed this study to determine the clinical implications and the effectiveness of arterial bypass surgery for limb salvage in patients with Buerger s disease. Methods: We retrospectively reviewed the patients with Buerger s disease and who underwent arterial bypass surgery between September 2003 and August 2008. We followed the criteria of Shionoya that was reported in 998 to diagnose Buerger s disease. The indications of surgery were patients with disabling claudication, severe resting pain, non-healing ulcer or gangrene, and non-diseased proximal and distal arteries were available for anastomosis. We evaluated the patency of the grafts with duplex ultrasonography or CT angiography after surgery. Results: Arterial bypass surgery was performed in 6 lower extremities of 4 patients. An autologous venous graft was used in 2 limbs and a polytetrafluoroethylene graft was used in 4 limbs. Major amputation was performed in 2 limbs and reconstruction with a myocutaneous free flap after minor amputation was performed in 2 limbs. The patency rates of the arterial bypasses were 66.%, 66.% and 66.% at, 3 and 5 years, respectively, and the limb salvage rates were 92.9%, 84.4% and 84.4% at, 3 and 5 years, respectively. Conclusion: Arterial bypass surgery could be considered as a favorable limb salvage treatment for the Buerger s disease patients with limited indications.

Olin 등 (3) 은금연은자발적인의지가가장중요한데버거병환자들이대부분젊은연령층이고낮은사회경제적지위에위치한경우가많아순응도가비교적좋지않고실제로교육수준이낮을수록효과적인금연이이루어지지않는다고하였다. 저자들의대상환자의경우추적관찰이소실된 명의환자를포함한 4명이외에는모두금연을실시하고있었는데이것은비교적높은저자들의이식편개존율에영향을미쳤을것으로생각된다. 그러나흡연이확인된세명중두명은족부궤양이있었으나동맥우회로술이후보존적치료를병행하며장기간에걸쳐궤양이호전된환자였으며한명은무릎아래하지절단술을시행받은환자임에도불구하고금연을하지않고있었다. 이로미루어보았을때수술후지속적인금연은물론하지의재생가능성이있을때악화를예방하고궁극적으로사지구제를위한금연의중요성을부각시키고경각심을일깨우는교육등이더욱적극적으로이루어져야할것으로생각된다. Willingendael 등 (4) 도말초동맥질환환자가동맥우회술을받은후에금연을하느냐흡연을지속하느냐에따른이식편개존율을조사한메타분석에서흡연을지속할경우그렇지않은경우에비해이식편의폐쇄율이세배임을보고하였고수술후환자의금연을돕기위한프로그램의마련이무엇보다중요함을강조하였다. 약물요법인프로스타글란딘제제의사용을금연과함께보조적으로활용한예는지금까지빈번하게보고되었다. European TAO study group(5) 에서는이중맹검법으로시행한경구용프로스타글란딘제제에관한연구결과대조군에비해실험군에서통증제거효과가있으며통계적으로유의한차이를보인다고발표하였고국내에서도 Ki와 Kim(6) 이이와유사한결과를보고하였다. 그러나버거병이보존적인방법으로치유되지않을때파행이나심한통증을유발하고족부의허혈성궤양을일으킬수있으며때로괴사로까지이어져결국하지절단을고려해야하는상황이발생할수있다. 버거병의주된환자군이젊은남성임을고려할때이질환이이들의삶의질에미치는영향과사회경제적손실을고려한다면더적극적인치료가이루어져야한다고사료된다. 이에수술적인치료를고려해볼수있는데수술방법으로는요부교감신경절제술과동맥우회술이있다. 요부교감신경절제술은피부및피하조직과같은표면적인

Gyun Ji Kim, et al:arterial Bypasses for Patients with Buerger s Disease 3 문에버거병환자에서요부교감신경절제술이용도는더욱감소하였다고하였고 Sasajima 등 (0) 은버거병환자에서요부교감신경절제술을시행한경우동맥우회술의이식편폐쇄율이오히려높아지는결과를보고하였다 (0). 저자들의경우에도요부교감신경절제술은시행하지않았다. 심한파행증, 고식적치료에반응하지않는심한휴식성통증및허혈성궤양이있는환자에서보다적극적인치료방법으로동맥우회술을고려해볼수있다. 죽상동맥경화증환자에비해버거병환자에서수술의성적은좋지못한데그이유는버거병은슬관절이하작은동맥이폐색되므로기술적으로용이하지않고동반된표재성정맥염으로인해자가정맥이식편사용이불가능한경우가상대적으로빈번하며성공적인동맥우회술후에도혈관염의진행에따른이식편폐색의위험이따르기때문이다 (0). Dilege 등 (8) 은동맥우회술의성공률을높이기위하여병변이없는혈관을문합에이용하는것을강조하였고이를위해술전및술중혈관조영술을시행할것을권장하였다. 이들은술전동맥조영술에서문합에적합하다고판단되었던동맥의 25% 가술중부적합하였다고보고하였고부적합한혈관에문합부를설치할경우이식편조기폐쇄율이높았음을보고하였다. 하지동맥우회술의개존율을높이기위해서는이식편의선택도중요한데인조혈관보다는자가혈관이식편이더좋은성적을보인다는것이보편적인개념이다 (9). Bozkurt 등 (20) 은 9명의환자에게서 20하지의동맥우회술을시행하였는데자가대복재정맥 0예, PTFE 7예, 복합이식편 (composite graft) 3예씩을사용하였고각각의개존율을 70%, 50%, 33.3% 로보고하였다. 저자들도자가정맥을 2예 (75%), PTFE 인조혈관을 4예 (25%) 에서사용하였고마지막추적관찰시점까지각각 75%, 50% 에서개통이잘유지되고있었다. 저자들의연구에서 PTFE 인조혈관을사용한 4하지는동측및반대측대복재정맥의길이가불충분하거나혈관벽이너무얇고역류가있어사용이어려운경우, 혹은과거에이미사용한경우였다. Ohta 등 (6) 은 0명의버거병환자를대상으로한후향적연구에서총 46예의동맥우회술을검토하였다. 그들은우회술의이식편개존율은기대에미치지못하였지만이식편개통기간동안일단허혈성궤양이치유되고나면그후이식편폐색이생기더라도지체절단 (6%) 은예방할수있다고주장하였다. Bozkurt 등 (20) 도동맥우회술의개존이수개월뿐이라할지라도사지의궤양이치유되기에충분하며그후에이식편의폐쇄가이루어지더라도허혈성병변의재발을유발하지는않는다고보고하였다. 그들은총 20예의동맥우회술을시행하였고 2예 (0%) 에서사지절단을시행하였다. 그러나저자들의경우에는심한족부궤양및괴저로동맥우회술 및발가락절단술을동시에시행받은환자를제외하면한명은궤양이호전되었으나두명은이식편이개통되어있음에도불구하고궤양의호전이없어서각각 7개월, 개월뒤결국중족골절단술, 발가락절단술을시행하였다. 반면하지파행증이주된수술적응증이었던 예에서동반된족부궤양이호전되지않아재우회술을고려하였으나원위부혈관이좋지않아재수술은시행하지않았고프로스타글란딘복용등보존적치료로궤양이치유된경우가있었다. 저자들의대상환자에서하지절단은총 6예중 2예 (2.5%) 에서시행하였고 5년하지구제율은 84.4% 로서기존의보고들과비슷한비율을보였다. 따라서버거병에있어동맥우회술은족부궤양의완전치유의기대는충족시키지못하더라도환자의삶의질에심각한영향을미칠수있는주요하지절단을최소화할수있는방법으로고려해볼만하다고사료된다. 결 버거병은금연이가장효과적인치료법으로알려진질환으로현재까지수술적방법이치료에기여하는비중은비교적높지않았다. 그러나금연이나약물치료에효과를보이지않는환자, 심한파행증이있는환자, 특히심한휴식성동통및이와동반된허혈성족부궤양이있는환자에게선택적으로동맥우회술을시행할경우하지보존의효과를경험하였다. 버거병환자중하지동맥우회술을시행할수있는환자는흔치않지만적절한환자를선택할경우세심한혈관수술과더불어유리피판을이용한족부재건술은버거병환자의삶의질을향상시킬수있는적극적치료방법의하나로고려해볼가치가있는것으로생각된다. 론 REFERENCES ) Buerger L.
