Coarctation of the aorta in patients younger than three months

Coartação de aorta em crianças até um ano: análise de 20 anos de experiência

“…The incidence of recoarctation, in 8 different papers with a total of 406 patients with up to a month of life, showed the average of recoarctation of 13,3%. However, in the age range of up to 3 months, the incidence lowered to 15%, and, under than 1 year of age, it was 10%, similar results to those found in the literature 8,19 . We believe, as a cause factor, in the insufficient resection of the ring of the anomalous tissue of the canal, associated to other series of factors.…”

“…Termino-Terminal recoarctation took place. In the same way, in the age range between 31 and 90 days, the incidence of recoarctation of 32%, although high, is similar to those found in other publications 8,19,23 . Currently it has been emphasized that the most efficient surgical technique to relieve the obstruction is the extended termino-terminal [7][8][9][28][29][30][31][32][33] .…”

“…When the patients showed hypoplastic aortic arch and isthmic hypoplasia -and the technique of Waldhausen was employed -, the incidence of total mortality was 33.3% and 21.4%, respectively, being such results very high. In infants over 30 days, the results are satisfactory, compared with results from other centers 8,[17][18][19][20][21][22][23][24][25][26][27] .…”

“…The presence of aortic arch hypoplasia increased the death risk in 1.9 times (DR=1.9 CI 95% 0.7-5.4) p=0. 19.…”

“…In our series, the incidence of recoarctation in the first month of life was 25%, regarded as high when compared with the international average [25][26][27] . The proliferation and constriction of residual canal tissue, still active during the first three months of life 18 , can show growth after surgical and be the cause of recoarctation 19 .…”
