Trial Information

Intraoperative Stereotactic Image-guided Navigation of Perforators for DIEP Flap Breast Reconstruction.


I. To analyze the accuracy of preoperative CT angiography in determining the location of
perforator vessels. Through the use of an intraoperative navigation system, we will
objectively locate perforators during surgery and compare the results to the preoperative
imaging assessment of the flap's vascular anatomy.

II. To determine whether the preoperative CT angiogram allows the microsurgeon to correctly
identify the perforators that are ultimately used as the pedicle for the flap.


Patients undergo deep inferior epigastric perforator (DIEP) flap breast reconstruction using
the StealthStation navigation system.

After completion of study treatment, patients are followed up at 1-2 weeks and 1 month, then
every 3 months for 2 years.

Inclusion Criteria:

Patients with histologically confirmed breast carcinoma or breast carcinoma in situ
desiring unilateral or bilateral deep inferior epigastric perforator (DIEP) flap breast
reconstruction Patients must be candidates for elective surgery, without clinically
significant cardiac or pulmonary disease (New York Heart Association [NYHA] class III/IV),
without infection requiring antibiotics, and without serious illness requiring the use of
steroids Patients must have normal kidney function and no allergy to intravenous (IV) dye
Patients with previous abdominal donor site flaps will be excluded along with patients
with previous extensive surgery to the anterior abdomen Patients with a weight of over 300
pounds or a body size not supported by the CT scanner will be excluded Patients who are
expected to undergo postoperative radiation therapy will be excluded
