For women exploring breast reconstruction after mastectomy, the DIEP flap is considered one of the most advanced, natural options available today. DIEP stands for Deep Inferior Epigastric Perforator flap, a microsurgical technique that uses your own abdominal skin and fat to rebuild the breast while preserving the abdominal muscles. Understanding how this procedure works can help you feel more confident and in control as you evaluate your options.
At PRMA Plastic Surgery, we specialize in advanced DIEP flap reconstruction, having performed over 15,000 successful procedures. As leaders in microsurgery, our focus is on precision and helping you achieve results that look natural, feel like your own, and support your long-term well-being.
What Is DIEP Flap Surgery?
During the DIEP flap procedure, skin and fat from the lower abdomen are carefully transferred to the chest to create a soft, natural-looking breast without implants or other foreign materials.
DIEP flap surgery preserves the abdominal muscles, helping maintain core strength and reducing long-term weakness. Because this procedure involves reconnecting tiny blood vessels under a microscope, it requires highly specialized microsurgical expertise, one of the key reasons patients seek out experienced centers like PRMA for breast reconstruction after mastectomy.
How Does DIEP Flap Surgery Work? The Microsurgical Process
Preoperative Planning and Imaging
Every DIEP flap surgery begins with detailed planning. A specialized scan called CT angiography (CTA) is used to map the blood vessels in your abdomen, allowing surgeons to identify the strongest, most reliable perforator vessels. Because every patient’s anatomy is different, this step is essential. It helps reduce operating time, improve precision, and support the best possible outcome.
Harvesting the DIEP Flap Tissue
During surgery, a low, hip-to-hip incision, similar to a tummy tuck, is made along the lower abdomen. Skin and fat are carefully separated from the underlying abdominal muscles, but the muscle itself is completely preserved. Only the tiny blood vessels (perforators) are dissected and used, which is what sets DIEP flap surgery apart from older procedures.
Microsurgical Blood Vessel Reconnection
The harvested tissue is then transferred to the chest, where the real microsurgical work begins. Using a high-powered microscope, surgeons reconnect the flap’s artery and vein to blood vessels in the chest. This step is performed using a dual-surgeon approach, with two experienced microsurgeons working together to enhance precision, reduce time under anesthesia, and improve outcomes.
Shaping the New Breast
Once healthy blood flow is established, the tissue is carefully shaped to create a natural breast mound that complements your body. Because this is living tissue, the reconstructed breast feels warm and soft and can change naturally with your body over time. For patients interested in restoring sensation, PRMA also offers TruSense®, an advanced technique that reconnects nerves during reconstruction to help bring feeling back to the breast.
DIEP Flap vs TRAM Flap: Why Muscle Preservation Matters
When comparing abdominal-based breast reconstruction options, the key difference between the DIEP flap and the TRAM flap comes down to muscle preservation. In a TRAM flap procedure, part or all of the rectus abdominis muscle is removed along with the tissue. In contrast, the DIEP flap carefully preserves the muscle, taking only the blood vessels (perforators) needed to support the transferred tissue.
This muscle-sparing approach leads to meaningful benefits for patients, including better long-term abdominal strength, a lower risk of hernia or bulging, and a smoother recovery overall. For these reasons, the DIEP flap is widely considered the modern evolution of the TRAM procedure, offering a more advanced solution for women seeking natural breast reconstruction after mastectomy.
What Makes DIEP Flap the Gold Standard in Breast Reconstruction?
- Natural look and feel: Uses your own living tissue, creating a breast that looks and feels soft, warm, and natural
- No implants required: Eliminates the need for foreign materials and future implant replacement surgeries
- Preserves abdominal strength: Muscle is left intact, supporting better core function and recovery
- Lower risk of complications: Avoids implant-related issues like capsular contracture, rupture, or BIA-ALCL
- Potential for sensation restoration: With advanced techniques like TruSense®, nerves can be reconnected to help restore feeling in the breast
- Adapts with your body: Because it’s living tissue, the breast can change naturally with aging and weight fluctuations
Who Is a Candidate for DIEP Flap Surgery?
Many women considering DIEP flap surgery wonder if they qualify, and in many cases, the answer is yes. While every patient is unique, here are some general guidelines:
- Adequate lower abdominal tissue: Enough skin and fat to create a natural breast shape
- Flexible timing options: Candidates may choose immediate reconstruction (at the time of mastectomy) or delayed reconstruction (months or years later)
- Prior abdominal surgery doesn’t automatically disqualify you: Many women who’ve had procedures like C-sections can still be eligible
- Personalized evaluation is key: A consultation with an experienced microsurgeon is the best way to determine what’s possible for your body and goals
- Accessible care, wherever you are: PRMA offers virtual consultations for out-of-state patients, making expert guidance easier to access
The best way to know for sure is to have a one-on-one conversation with a specialist who can guide you toward the safest, most effective option for your situation.
