Answer

Significant recoarctation (6-33% in infants, 0-18% in older children) [37, 48] ; formation of aneurysms in all types of coarctation repair, [44] particularly well-documented following prosthetic patch angioplasty [48, 49] ; development of paraplegia [20, 21, 50] ; paradoxical hypertension [22, 23, 24] ; and vascular complications related to subclavian flap repair [51, 52, 53, 54, 55] continue to be problems.

In a study examining long-term results of surgery by MRI of 247 patients aged 33.0 ± 12.8 years, restenosis (mild in 31% and significant in 9%) and dilatation of the aortic segment (13%), with discrete aneurysm at the repair site in 9%, was observed. However, antihypertensive therapy was required, which controlled the blood pressure in 93% patients. [56] Mortality rate was low, but significantly higher than age-matched healthy controls.

Late hypertension continues to be a problem. [57]
