A new sutureless intraluminal graft was developed with an elastic ring made of a flat spring. The diameter of the ring could be reversibly reduced by compression. The sutureless intraluminal graft with an elastic ring can attach itself to the vessel wall by elastic expansion of the ring. The elastic-ring graft was implanted in the descending thoracic aortas of nine dogs and was evaluated histologically and angiographically at different intervals from 18 to 150 days. No complication such as detachment of the ring, aortic rupture, stenosis, or aneurysmal dilatation was observed. With the new graft neither ligation nor posterior aortic wall dissection is necessary, and no anastomotic stenosis occurs. This graft is applicable even if the diameter of the aorta is small. Therefore the elastic-ring sutureless intraluminal graft promises theoretic advantages over sutureless methods that use tape ligation.
一种新型无缝腔内移植物由扁平弹簧制成的弹性环开发而成。环的直径可通过压缩可逆地减小。带有弹性环的无缝腔内移植物可通过环的弹性扩张附着于血管壁。将弹性环移植物植入9只犬的胸降主动脉，并在18至150天的不同时间间隔进行组织学和血管造影评估。未观察到环脱落、主动脉破裂、狭窄或动脉瘤样扩张等并发症。使用这种新型移植物既不需要结扎也不需要主动脉后壁剥离，并且不会发生吻合口狭窄。即使主动脉直径较小，这种移植物也适用。因此，弹性环无缝腔内移植物与使用胶带结扎的无缝方法相比具有理论优势。
