Objective To explore the effect of the intensive CT on the deep inferior epigastric perforator (DIEP) flap design strategy. Methods From June 2007 to March 2008, 7 patients received reconstructive operation of the vertical DIEP flap, among whom there were 5 females with congenital absence of vagina and 2 males with peno-scrotal Paget’s disease,aged 18-62 years old. Before the operation, the intensive CT scans were appl ied to all the petients in search for DIEP. The flaps were designed according to the radiological findings. The scrotum and penis defects were reconstructed in 2 cases and vaginal reconstruction was performed in 5 cases. The flap dimension ranged from 15 cm × 7 cm to 22 cm × 5 cm. The donor site was closed directly. Results A total of 10 ideal perforating branches of all the 7 DIEP flaps were found before the operation, with the diameter of over 1.5 mm. Of the 7 flaps, 4 had 1 perforating branch and the other 3 had 2 perforating branches. All 7 flaps survived completely. The incisions of 6 patients obtained heal ing by first intention. Only 1 patient with Paget’s disease had erosion at the scrotum incision and partial necrosis 7 days after the operation, and then healed after discontinuous dressing change. The incisions at the donor site obtained heal ing by first intension. Two patients complained about draw-off at the lower abdomen on the operated side, which was basically rel ieved at 7 days after the operation. All patients were followed up for 1 to 10 months (4.5 months on average). No operation-related compl ication was observed after operation. Six patients were satisfied with the reconstructive results. Only 1 patient was dissatisfied with the buried pennies and requested a revision. Conclusion The intensive CT scans play an important role in the DIEP flap design. It can not only make the flap safer, but also decrease operation time and improve efficiency.
ObjectiveTo explore the feasibil ity and rel iabil ity of rib-sparing technique for internal mammary vessels exposure and anastomosis in breast reconstruction and thoracic wall repair with deep inferior epigastric perforator (DIEP) flaps. MethodsBetween November 2009 and September 2011, 11 female patients with post-mastectomy deformities were treated. The mean age was 42 years (range, 33-65 years). Of them, 10 patients underwent breast reconstruction with the DIEP flaps, and 1 patient received defect repair for chronic thoracic wall irradiated ulcer with the DIEP flap. The size of the flap ranged from 18 cm×9 cm to 28 cm×12 cm. Rib-sparing technique was applied in all these cases. The internal mammary vessels were exposed by dissection intercostal space and anastomosed with the deep inferior epigastric vessels. The donor sites were closed directly in all cases. ResultsIn all cases, the rib-sparing technique for internal mammary vessels exposure and anastomosis was successfully performed. The mean time for internal mammary vessels exposure was 52 minutes (range, 38-65 minutes). The mean exposure length of the internal mammary vessels was 1.7 cm (range, 1.3-2.2 cm). All flaps survived completely postoperatively, and wounds and incisions at donor sites healed primarily. All patients were followed up 8-26 months (mean, 12 months). All patients were satisfied with the reconstructive outcomes. No collapse deformity or discomfort of the thoracic wall occurred. ConclusionThe rib-sparing technique for internal mammary vessels exposure and anastomosis is a rel iable and reproducible approach to reconstruct the breast and repair the thoracic wall with DIEP flap, and it can reduce collapse deformity of the thoracic wall.
