PURPOSE: The reduced size of @entity1028 ( @entity1028 ) after endovascular repair suggests lowered intraaneurysmal pressure. In the presence of @entity1070 , the size is not decreased. Although postoperative intraaneurysmal pressure is difficult to record, the pulsatile wall motion (PWM) of @entity439 can be measured noninvasively. The aim of this study was to assess the PWM of @entity1028 before and after endovascular repair and to relate the change in the PWM to aneurysmal size and presence of @entity1070 . METHODS: Forty-seven @entity1 underwent endovascular repair of an AAA. The @entity439 diameter and PWM were measured with the use of ultrasonic echo-tracking scans preoperatively; at 1, 3, and 6 months; and thereafter biannually. Fifteen @entity439 developed @entity1070 , whereas 32 were completely excluded. The leaks were characterized with the use of computed tomographic scanning and angiography. Median follow-up was 12 months (interquartile range, 5 to 24 months). RESULTS: The preoperative PWM of the @entity439 was 1.0 mm (range, 0.8 to 1.3 mm). After complete endovascular exclusion, the PWM was 25% (range, 16% to 37%) of the preoperative value (p < 0.001), and @entity439 diameter decreased by 8 mm (range, 6 to 14 mm) (p < 0.001). After 18 months, no further diameter reduction occurred. In three @entity1 without @entity1070 but with enlarging @entity439 , the postoperative PWM showed less reduction (p < 0.05). @entity439 with @entity1070 showed no diameter decrease, and the postoperative PWM was 50% higher than that in the totally excluded cases (p < 0.01). In five @entity1 with transient @entity1070 , the PWM was reduced after leakage ceased (p < 0.05). Leaks of various sources displayed similar PWM. CONCLUSION: The size and PWM of @entity439 are reduced after endovascular repair. The diameter reduction may cease after 1.5 years. Endoleaks are associated with higher PWM than expected. Pressure may be transmitted without evidence of leaks.
