Autologous Breast Reconstruction
DIEP Flap: Reconstruction Without an Implant
DIEP stands for Deep Inferior Epigastric Perforator — the blood vessels that supply a section of abdominal skin and fat. In a DIEP flap procedure, this tissue is carefully harvested from the lower abdomen, transferred to the chest, and reconnected to blood vessels there using microsurgery. The result is a breast reconstructed entirely from your own living tissue — no implant required.
The DIEP flap is considered by many reconstructive surgeons to be the gold standard of autologous breast reconstruction because it creates the most natural-feeling breast — warm, soft, and changing with your body over time — while sparing the abdominal muscles entirely, which was not possible with earlier flap techniques like the TRAM flap.
DIEP vs. TRAM Flap: Why Muscle Preservation Matters
The predecessor to the DIEP flap was the TRAM flap (Transverse Rectus Abdominis Myocutaneous flap), which used the same abdominal skin and fat but also sacrificed the rectus abdominis muscle to carry the blood supply. DIEP is a refinement that isolates the perforating blood vessels running through the muscle without taking the muscle itself.
✓ DIEP Flap (Muscle-Sparing)
- Rectus abdominis muscle left intact — full abdominal strength preserved
- Lower risk of long-term abdominal weakness or hernia
- Faster return to full activity (4–6 weeks vs. 8–12 for TRAM)
- Less postoperative abdominal pain than TRAM
- More demanding technically — requires microsurgical expertise
- Standard of care at high-volume reconstructive centers
TRAM Flap (Older Technique — Muscle Sacrificed)
- Rectus muscle partially or fully sacrificed with the flap
- Higher rates of abdominal weakness, bulge, or hernia
- Longer functional recovery time
- Pedicled TRAM (no microsurgery) is simpler but higher donor-site cost
- Still appropriate in some patients when microsurgery is not available
- Largely replaced by DIEP at centers with microsurgical capability
What Is Microsurgical Breast Reconstruction?
Microsurgery refers to surgery performed under an operating microscope, connecting blood vessels that are 1–2mm in diameter. In DIEP reconstruction, the deep inferior epigastric artery and vein from the abdomen are connected to the internal mammary artery and vein in the chest wall. This anastomosis (connection) restores blood flow to the transferred tissue, allowing it to survive permanently in its new location. The surgery takes 6–10 hours and requires specialized training in microsurgical technique.
"The DIEP flap gives patients a breast that feels like a part of them — because it is. It changes with body weight, ages naturally, and doesn't require the long-term monitoring of an implant."
— Dr. Farhad Rafizadeh MD FACS
DIEP Flap Candidacy — Patient Factors
| Factor | Candidacy | Notes |
|---|---|---|
| Adequate abdominal tissue | Ideal | Moderate lower abdominal tissue provides sufficient volume for one or both breasts |
| Prior tummy tuck (abdominoplasty) | Disqualifying | DIEP perforator vessels are disrupted; alternative donor sites must be considered |
| Prior C-section or Pfannenstiel incision | Evaluate | Perforators may be present; CT angiography or Doppler mapping determines feasibility |
| Active smoker | Not Recommended | Smoking severely impairs microvascular anastomosis success; cessation required 4–6 weeks minimum |
| Obesity (BMI > 35) | Evaluate | Higher flap loss risk; may require weight optimization; individualized decision |
| Prior chest radiation | Often Preferred | Autologous tissue brings new blood supply to irradiated field — a major advantage over implants in radiated chests |
| Bilateral mastectomy | Excellent Option | Single abdominal flap can supply tissue for both breasts simultaneously in many patients |
| Very thin patient, minimal abdominal tissue | Alternative Sites | PAP flap (thigh), SGAP flap (buttock), or implant reconstruction may be preferred |
Surgery & Recovery Overview
DIEP flap reconstruction is a long operation — typically 6–10 hours for unilateral (one breast) and 8–12 hours for bilateral (both breasts). Most patients stay 3–5 days in the hospital while nursing staff monitors flap perfusion (blood flow). The first 72 hours are the most critical period for flap monitoring.
Other Autologous Flap Options
When the abdomen is not available or does not provide sufficient tissue, other donor sites can be used:
PAP Flap
Profunda Artery Perforator — uses skin and fat from the inner/posterior thigh. Good option for thin patients who lack abdominal tissue. Hidden scar in the thigh crease.
SGAP / IGAP Flap
Superior or Inferior Gluteal Artery Perforator — uses buttock tissue. Provides dense, firm fat. More technically challenging vessel anatomy.
Latissimus Dorsi Flap
Back muscle and skin rotated to the chest. Does not require microsurgery. Often combined with an implant for adequate volume. Leaves a back scar.
TRAM Flap (Pedicled)
Older technique using abdominal tissue on a muscle pedicle — no microsurgery required but sacrifices rectus muscle. Now largely replaced by DIEP at experienced centers.
Dr. Rafizadeh performs DIEP flap reconstruction at a fully accredited surgical facility in Morristown, NJ, serving patients throughout Morris County, Essex County, Bergen County, and Union County. Women from Parsippany, Short Hills, Summit, Chatham, Livingston, Madison, Montclair, and across North Jersey travel to his practice for complex breast reconstruction. He also sees patients from New York City who prefer a board-certified plastic surgeon with decades of reconstructive experience just outside the city.
