Surgery for recurrent pectus deformities.

BACKGROUND

Pectus repair in adults can be challenging. Standard repair has been the modified Ravitch procedure. More recently the minimally invasive Nuss procedure, used exclusively in children, has been introduced for correction of pectus deformities in adults. There is a paucity of data on which procedure is most appropriate for adults and even less information on the most appropriate operation for pectus recurrence in adults. The purpose of this study is to determine if any specific patient characteristic exists that places patients at an increased risk for recurrence and describe our management of recurrent pectus defects in adults.

METHODS

We retrospectively reviewed the records of all patients (>16 years of age) who underwent primary or recurrent repair of pectus deformities from April 1999 through December 2006.

RESULTS

Forty-eight patients, 37 (77%) men and 11 women, underwent pectus repair with a median age of 28 years (range, 16 to 54 years). Indication for initial repair was pectus excavatum in 39 (81%) and pectus carinatum in 9. The primary procedure was a modified Ravitch repair in 40 patients and a Nuss procedure in 8. Thirteen patients (27%) underwent reoperation for recurrence; 8 (62%) patients had undergone a previous Nuss procedure and 5 had a modified Ravitch repair. All reoperative patients had a primary pectus index (PI) greater than 4.0, while 8 (62%) also had an asymmetrical defect. All failed Nuss procedure patients underwent a modified Ravitch repair for correction, while the recurrent open repair patients required complex reconstructions. Results were good or excellent in greater than 90% of patients undergoing a reoperative procedure.

CONCLUSIONS

Adults with severe pectus deformities (PI > 4.0) and asymmetric defects are at a greater risk of recurrence after a Nuss procedure. These patients may better be served with a modified Ravitch repair initially. Reoperation for failed pectus repair in adults can be performed safely with outstanding results.
