Answer

Complications such as paraplegia [20, 21, 50] and paradoxical hypertension [22, 23] are seen following surgical repair, although such complications are rare and, if present, very mild and inconsequential following balloon angioplasty. Aneurysms following balloon angioplasty [48, 77, 78] are of concern and need further study, although such aneurysms are also seen with surgical repair. [44] The femoral artery occlusion rate following balloon angioplasty may be higher than that seen with surgical therapy. However, vascular complications can occur in the left upper limb following coarctation repair with subclavian flap aortoplasty; these complications include gangrene, reduction in the length and muscle mass of upper arm and forearm, and abnormal Doppler blood flow velocities in brachial arteries, suggesting potential for symptoms of ischemia.
