Type II endoleak-like bleeding after open abdominal aortic aneurysm (AAA) repair is extremely rare. We report a case of aneurysm sac re-expansion in a 71-year-old man 13 years after open AAA repair. The wrapped aneurysm expanded from 55 mm to 70 mm, with a computed tomography scan showing contrast medium inflow from the aneurysm wall. Reoperation revealed diffuse bleeding without discrete branch vessel hemorrhage. This case demonstrates that type II endoleak-like bleeding can occur as a late complication after open AAA repair, even without bleeding from the branch vessels, highlighting the importance of long-term surveillance.
开放性腹主动脉瘤（AAA）修复术后出现II型内漏样出血极为罕见。我们报告一例71岁男性在开放性AAA修复术后13年出现动脉瘤囊再扩张的病例。包裹的动脉瘤从55毫米扩大到70毫米，计算机断层扫描显示有造影剂从动脉瘤壁流入。再次手术发现弥漫性出血，无明显分支血管出血。该病例表明，即使没有分支血管出血，II型内漏样出血也可能作为开放性AAA修复术后的晚期并发症出现，凸显了长期监测的重要性。
