今回当科で経験した脾動脈瘤３例について報告する．年齢は17歳から76歳（平均49.3歳）で、女性；１例、男性；２例であった．１例は破裂症例で緊急開腹，それ以外の２例は血管内治療を施行し,全て術後経過は良好であった．緊急開腹術を行った１例は２cm 未満の嚢状瘤であり，術前瘤径にとらわれず治療適応を考える必要がある．治療の第一選択として低侵襲な血管内治療を考慮する必要がある．We report 3 cases of splenic artery aneurysm (2 males,1 female; median age, 49.3 years; age range, 17-76 years).We performed splenectomy (included aneurysm) in emergency surgery for one ruptured case and performed endovascular therapy for two unruptured cases. The postoperative progress of all cases was satisfactory.Emergency case was saccular aneurysm under 2cm of size. Indication for treatment of intraabdominal aneurysm may be considered even in small size of aneurysm.All cases are still alive. It is necessary to take into account minimally invasive endovascular therapy in first-line
