To assess the effect of stent-graft implantation on the pressure within an abdominal aortic aneurysm.
Aneurysm exclusion was performed using an aorto-uniiliac stent-graft in eight patients. Following stent-graft implantation, pressure measurements were performed through a catheter adjacent to the graft in the aneurysm. This "aneurysm pressure" was compared with radial arterial pressure.
The pressure was lower in the aneurysm than in the radial artery, in all cases. Mean aneurysm pressure was 36.5/33.8 mmHg, while mean radial arterial pressure was 118.5/50.5 mmHg (p < 0.05, for both systolic and diastolic pressures). These findings corresponded with a reduction in the palpable abdominal pulse, and an absence of perigraft perfusion on follow-up computerised tomography.
Stent-graft implantation produces a fall in the pressure within an abdominal aortic aneurysm.
评估覆膜支架植入对腹主动脉瘤内压力的影响。
对8例患者采用主动脉单髂支覆膜支架进行动脉瘤隔绝术。在植入覆膜支架后，通过动脉瘤内与支架相邻的导管进行压力测量。将这种“动脉瘤压力”与桡动脉压力进行比较。
在所有病例中，动脉瘤内压力均低于桡动脉压力。动脉瘤平均压力为36.5/33.8 mmHg，而桡动脉平均压力为118.5/50.5 mmHg（收缩压和舒张压均p < 0.05）。这些发现与腹部可触及搏动减弱以及随访计算机断层扫描显示无支架周围灌注相符。
覆膜支架植入可使腹主动脉瘤内压力降低。
