[Aortic arch advancement surgery as treatment for aortic coarctation with hypoplastic aortic arch in children]. / Avance de arco aórtico en el manejo de la coartación de aorta con hipoplasia del arco aórtico en niños.

ABSTRACT

INTRODUCTION: Treatment of aortic coarctation with hypoplastic aortic arch is still a surgical challenge. The aortic arch advancement surgery has shown less re-coarctation frequency. OBJECTIVE: To determine the re-coarctation frequency in patients who underwent aortic arch advancement technique for aortic coarctation with hypoplastic aortic arch and analyze the results. MATERIAL AND METHODS: Retrospective and observational study of 38 patients who underwent aortic arch advancement in a third level Institution from 2002 to 2010. RESULTS: Twenty four males and 14 females all with aortic arch Z index diameter of < or = -2 were found. The median age was 2.6 months and the median weight was 3.8 kg. Twelve patients (31.5%) did not show post operative complications. Eighteen (47%) had only one complication; one patient (2.6%) had 2 complications and 2 (5.2%) had 3 complications. After a follow up of 3.7 years the frequency of re-coarctation was O%. DISCUSSION: With the previously mentioned technique the recoarctation frequency on medium and long term basis was 0%. From the anatomical and functional point of view, we believe this technique offers the best possible results.
