Significats de better patency en anglès

Conclusions: PTFE-TIPS were more effective at preventing variceal re-bleeding than bare metal stents due to better patency.

Heparin bonding may be an important improvement of ePTFE, resulting in better patency rates for vascular reconstructions.

Conclusions: Lower-extremity vascular access has acceptable results in terms of patency, with femoral vein transposition having better patency rates than femoral grafts.
