hyperemic flow or antegrade flow post graft procedure after several weeks is caused by | chronic vasodilation |
T/F graft velocities vary with vessel diameter | True |
complications of stents include all but: endoleak, intimal hyperplasia, infection, vessel rupture, embolization | intimal hyperplasia |
