Answer

The following are perceived advantages of stents over balloon angioplasty:

  • The ability to expand tubular long-segment coarctation, hypoplastic isthmus, and the distal transverse aortic arch

  • The ability to increase the coarcted segment diameter independently of the intimal tear

  • The ability to decrease the probability of restenosis

  • The ability to prevent dissection of the torn intimal flap by facilitating apposition of the intima against the media

  • The ability to prevent aneurysms because of the support of the weakened aortic wall with the stent and neointima
