A 66-year-old man presented with hemolytic anemia, which required frequent blood transfusion, 6 months after surgical repair of an ascending aortic pseudoaneurysm. Hemolysis was attributed to luminal stenosis caused by graft kinking by laboratory test, CT and four-dimensional magnetic resonance imaging. First, an Excluder cuff was placed at the stenotic site under rapid pacing, but it migrated distally. Thereafter a Palmaz XL stent was placed at the stenotic site, which led to resolution of anemia. In this case, a Palmaz XL stent was successfully used to treat hemolytic anemia caused by graft kinking following ascending aortic surgery.
一位 66 岁男性在升主动脉假性动脉瘤修复手术后 6 个月时出现溶血性贫血，需要频繁输血。实验室检查、CT 和四维磁共振成像提示吻合口狭窄导致血管内狭窄，吻合口扭曲导致溶血。首先，在快速起搏下在狭窄部位放置 Excluder 袖带，但袖带向远端迁移。此后，在狭窄部位放置 Palmaz XL 支架，导致贫血缓解。在本例中，成功使用 Palmaz XL 支架治疗升主动脉手术后吻合口扭曲导致的溶血性贫血。
