Bilateral DIEP flap needs two groups of vessel pedicles. We suppose that the bilateral DIEP flap may survive on one vessel pedicle by means of interconnection of bilateral DIEA. This study is aimed to build a interconnected vessel system of bilateral DIEP flap based on one vessel pedicle and observe its survival in breast reconstruction.

Study Start Date: January 2007
Study Completion Date: May 2009
Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
Patients who receive breast reconstruction with bilateral DIEP flap based on bilateral vessel pedicles
Procedure: DIEP
flap survival, operation time, flap complications, donor site morbidity.
Experimental: 2
Patient who receive breast reconstruction with vessel interconnected DIEP flap based on one vessel pedicle
Procedure: Interconnected DIEP
flap survival, operation time, flap complications, donor site morbidity.

Detailed Description:
The DIEP flap have become the most common and primary choice in autogenous tissue breast reconstruction nowadays. In cases with inadequate abdominal soft-tissue volume or abdominal midline scar, the bilateral DIEP flap is needed.However, it need two groups of recipient vessels. So it is unavailable in cases short of two groups of recipient vessels after radiotherapy. This study is aimed to solve the problems by interconnecting one of the branches of DIEA each side. The MDCT will be used to predict the branches and perforators of DIEA both sides. According to the branches of DIEAs, one branch will be anastomosed with that on contralateral side with only one vessel pedicle preserved on one side. We believe that the whole flap can be completely nourished with only one vessel pedicle by means of vessel interconnection.
