Coarctation of the aorta: an evaluation of surgical techniques.

Coartación de la aorta: Evaluación de técnicas quirúrgicas

Nozar, José V - Galíndez, Eduardo M - Neirotti, Rodolfo - Kreutzer, Guillermo

Resumen:

Since 1961, 187 patients were operated upon because of a coarctation of the descending thoracic aorta. Fifty three of these patients were Jess thanone year o!d; and 86 % had associated cardiac. iesions. Two different types of surgical techniques were used: resection and end-to-end anastomosis (79 cases) an angioplasty in, 99 cases. The most common associated defects found in the small infant group were patent ductus arteriosus or ventricular septal defect. Surgical treatment was indicated in this group, when medica] treatment was found incapable of reducing cardiac failure. In the older children group, the most frequent associated Jesions were: obstruction to theJeft ventricular outflow tract ( aortic valvular stenoses or subaortic stenoses). Indications as which of both lesions have to be treated first is decided accordingto which has the. most important gradient. Patch graft angioplasty is considered to be the best operative procedure for coarctation in small infants and for treatmentof recoarctation of the aorta. We think resection and end-tq-end anastomosis still has a place in the treatment of coarctation specially in these favourable cases with a short coarted segments. In our experience the best age for correction of this congenital malformation in assymptomatic patients is around four years of age.


Desde 1961 a 1975, 187 pacientes con coartación de aorta torácica han sido operados en este Servicio. Cincuenta y tres eran menores deun ruño de edad y el 86 % de ellos tenían defectos cardíacos asociados. Se realizaron fundamentalmente dos tipos de técnica quirúrgica: resección y anastomosis término-terminal (79casos), o algún tipo de ang,oplastía (99 casos). Las malformaciones a,sociadas, excepto el ductus arterioso, fuerqn tratadas en un segundotiempo, aunque en 9 pacientes conjuntamente a la reparación de la coartación aórtica se realizó oerclage de la arteria pulmonar. Se estudian las indicaci:ones :de )a cirugía en los lactantes, con especial énfasis al tratamiento de la ooartación de aorta a;sociada a alteraciones valvulares aórticas y sub-aórticas y a fibroelas- · tosis endocárdica. Se discuten los detalles técnicos de la angioplastia y las ventajas que brfüda su uso, como s,er el eliminar el riesgo de constricción circular a nivel de la anastomosis y de tensión en la línea de sutura; el facilitar la hemostasis post-declampeo; el retener pared posterior de aorta y el adaptarse a asi todos los tipos de coartación. Se concluye recomendando este procedimiento como de rutina en el tratamiento quirúrgico de la coartación de aorta _ torácica del lactante y el niño menor.
