Breast reconstruction with deep inferior epigastric perforator flap (DIEP flap) is an optimal technique for massive tissue defect after breast cancer surgeries. Venous congestion is one of the main complications and the probable reasons include thrombus, lack of ramus communicans across the midline or between deep and superficial system, improper choice of anastomotic vein, et al. Clinical examination is the main method, and other auxiliary tests can also be used. Preoperative vascular evaluation is of great importance. The venous superdrainage is current preventive measure for congestion.

Objective To present the clinical effect of the delayed tissue expanding breast reconstruction with implants.Methods For those who received breast tumor surgeries,round-shaped expander was implanted for increasing skin coverage and silicone implant was used for breast reconstruction after several months' expanding.Results 15 relevant cases were included in this study with an average of 5.1 months expanding period.Only one patient received reoperation for capsular contracture and there was no complication in the other cases.Conclusions Delayed tissue expanding breast reconstruction with implants,with a wide indication,is an ideal reconstructive method which can reduce the interference of tumor recurrence and radiotherapy and avoid the trauma of donor site and the patch-like appearance of breast.
