Forty-two patients underwent replacement of the thoracic aorta with a sutureless intraluminal graft. Early and long-term results were evaluated. The operative mortality rate was 7.1%. There were two postoperative complications related to a ringed graft. One complication, the formation of a pseudoaneurysm, was caused by insufficient fixation of the graft; the other, a cerebral infarction, was related to the location of the proximal anastomosis with respect to the origin of the left subclavian artery. The 3- and 5-year actuarial survival rates were 86 and 69.5%, respectively. These were similar to survival rates of age-matched controls in the general Japanese population. Replacement of the thoracic aorta using a sutureless intraluminal graft can be performed with acceptable operative mortality, with good long-term results.
42例患者接受了无缝腔内移植物置换胸主动脉手术。对早期和长期结果进行了评估。手术死亡率为7.1%。有2例术后并发症与带环移植物有关。其中1例并发症为假性动脉瘤形成，原因是移植物固定不充分；另1例为脑梗死，与近端吻合口相对于左锁骨下动脉起源的位置有关。3年和5年精算生存率分别为86%和69.5%。这些与日本普通人群中年龄匹配对照组的生存率相似。使用无缝腔内移植物置换胸主动脉可以在可接受的手术死亡率下进行，且长期效果良好。
