ABSTRACT

Breast reconstruction with TRAM flap (a myocutaneous flap of the rectus abdominis muscle) needs the return of the sensibility to become a complete surgery. A new surgical technique, proposed by Doncatto and Hochberg sutures both the eleventh intercostal nerves of the TRAM flap to thoracic intercostal nerves. Fifty four patients submitted to breast reconstruction with TRAM flap were evaluated. Twenty seven patients were reinnervated and twenty seven were in a control group. The recuperation of the superficial feeling was the big conquest of this surgery, and it was present in all the twenty two (81,5%) (chi square test p < O,05) patients reinnervated on the 8th month after the surgery. In the control group the superficial feeling was present only in three case (11,2%). The return of the feeling occurred in all the cutaneous surface of the TRAM flap. There was an increase in the response to the tests some time after the surgery. Deep pressure and vibration tests were positive in all the twenty patients. Superficial pain and temperature were present in eight cases of reinnervated group and one case of control group.

RESUMO

A reconstrução mamária com o TRAM flap (retalho miocutâneo de músculo reto abdominal) precisa do retorno da sensibilidade para ficar uma cirurgia completa. Uma nova técnica cirúrgica posposta por Doncatto e Hochberg sutura ambos os décimo-primeiros nervos intercostais do TRAM flap com nervos intercostais torácicos. Foram avaliados cinquenta e quatro pacientes submetidas a reconstrução mamária com TRAM flap. Foram vinte e sete pacientes reinervadas cirurgicamente e vinte e sete no grupo controle. A recuperação de tato superficial foi a grande conquista desta cirurgia em vinte e duas pacientes reinervadas no 8º mês após a cirurgia duas pacientes (81,5%) (teste qui-quadrado P< 0,05). No grupo controle o tato superficial esteve presente apenas em três casos (11,2 %). O retorno do tato ocorreu em toda a superfície cutânea do TRAM flap. Houve aumento de resposta aos testes com o passar do tempo pós-cirúrgico. Os testes de pressão profunda e vibração foram positivos em todas as pacientes. A dor superficial e a temperatura estiveram presentes em oito casos do grupo reinervado e três casos do grupo controle.
