Acute and follow-up intravascular ultrasound findings after balloon dilation of coarctation of the aorta.

Abstract: There is a high incidence of intimal tears and dissections immediately after balloon angioplasty for native and recurrent CoAs. Intravascular ultrasound is more sensitive than angiography in detecting the vascular wall changes. Even significant intimal tears are not necessarily associated with aneurysm formation, and many decrease in size or disappear at short-term follow-up.

“…Therapeutic tears may or may not be visible by angiography, but they are almost always seen by intravascular ultrasound (IVUS). 1 When therapeutic tears are evident on angiography, contrast is confined to the aortic wall in the radial dimension, and to the CoA segment axially, and there may be a small intimal flap (Figure 1). 2 By definition, a therapeutic tear should involve only the narrow region of the CoA segment, but the location around the circumference of a CoA is not predictable.…”

“…Wykazano, że korzystny wynik zabiegu (redukcja gradientu ciśnień, wyrównanie obrysu naczynia oraz prawidłowe spoczynkowe ciśnienie tętnicze) nie zwalnia od obowiązku stałej okresowej kontroli pacjentów [24,25]. Jest to istotne z powodu możliwo-ści pojawienia się w różnym, czasami odległym, okresie po zabiegu nawrotnego zwężenia czy też tętniaka.…”

“…O conhecimento dessas informações morfológicas podem ser úteis na escolha do diâmetro adequado do balão e na identificação e mecanismo de formação de aneurismas pós dilatação. As alterações da íntima identificadas pelo ultra-som intravascular pós dilatação são similares na coarctação da aorta nativa e na recoarctação 56 . O processo de cicatrização e remodelamento de ambos também parecem similar.…”
