Endovascular aneurysm repair (EVAR) has developed as a less invasive alternative to open surgery for patients with abdominal aortic aneurysms. However, patients with very short infrarenal necks require complex surgical open repair, which is associated with increased mortality and morbidity. The risk of complex open repair may be prohibitive in high-risk patients. Thus, modifying the technique of EVAR may be required in such patients to successfully exclude aneurysms. An alternative that can be used in these patients is the so-called "chimney graft" technique. We report two cases where the chimney graft technique was used with good immediate results.
血管内动脉瘤修复（EVAR）已成为治疗腹主动脉瘤患者的一种较微创的替代开放手术的方法。然而，对于肾下极非常短的患者，需要进行复杂的开放手术修复，这与死亡率和发病率的增加相关。对于高危患者，复杂的开放修复的风险可能是不可接受的。因此，可能需要对这些患者进行 EVAR 技术的修改，以成功排除动脉瘤。在这些患者中可以使用的另一种方法是所谓的“烟囱移植物”技术。我们报告了两例使用烟囱移植物技术的病例，结果良好。
