Dissection of the descending aorta after balloon angioplasty of native coarctation.
A 12-year-old girl underwent successful balloon angioplasty for a waist-like native coarctation. The balloon size/coarctation diameter ratio was 3.3. Postdilatation angiography showed a small aneurysm at the coarctation site. On frequent review the patient remained symptom-free and normotensive. Recatheterization was performed 14 months after balloon aortoplasty, when angiography revealed a massive aortic dissection extending from the origin of the left subclavian artery to both iliac arteries. She underwent partial replacement of the thoracic aorta. Balloon angioplasty of a narrow waist-like native coarctation may lead to extensive wall dissection and should be considered critically.
