Real-time B-mode ultrasonography was used to study in vivo the behavior of bifurcated aortic grafts (Dacron knitted) implanted over a period of 1 to 88 months previously in 67 patients, 28 of whom (42 per cent) were hypertensive. Most grafts showed an increase in size, when compared with the original one, which appeared to be closely related to arterial pressure (P less than 0.05). This increase was not dependent on the time elapsed from implant.
实时B型超声检查用于在体内研究67例患者先前1至88个月内植入的分叉式主动脉移植物（涤纶编织）的情况，其中28例（42%）为高血压患者。与最初的移植物相比，大多数移植物尺寸增大，这似乎与动脉压密切相关（P<0.05）。这种增大并不取决于植入后的时间。
