I can’t say enough good things about Dr. Gupta and his team. As a healthcare worker, I strongly feel that, when looking for a good surgeon, you should always ask the surgical nurses who to go to. The nurses I work with all said that Dr. Gupta would be their first choice for a plastic surgeon.

SGAP Flap
What Is a SGAP Flap?
SGAP stands for Superior Gluteal Artery Perforator flap; this name comes from the vessels in the buttocks which are needed in order to perform this “free flap” type of reconstruction. The blood vessels from the gluteal area are reattached to the blood vessels in the chest so the flap can develop its own blood supply and thrive. The gluteal tissue is then shaped into a natural looking breast.
Who Is a Good Candidate?
- You plan to have a mastectomy and do not want breast implants.
- Has history of radiation therapy.
- Has failed implant reconstruction and/or other autologous reconstruction.
- You have a history of abdominoplasty or other abdominal surgery.
- You should be at or close to your ideal weight, with a BMI less than 35.

- The best candidates are non-smokers. Smoking increases the chance of complications including impairment in wound healing.
The Procedures
- You will see Dr. Gupta prior to surgery. He will draw his surgical plan on your gluteal area and breast.
- The duration of surgery often rages from 8-12 hours, depending on the complexity of the case.
- During surgery Dr. Gupta will first evaluate the blood vessels in the chest. He will explore and dissect these vessels ensuring they are patent enough and have a large enough diameter to sew the abdominal vessels to. After the chest vessels have been evaluated and prepared Dr. Gupta will begin to raise the gluteal flap.
- An incision will go from along the low back from midline to hip. Fat and skin will be raised leaving the glute muscle attached. The SGAP vessels will be detected and carefully dissected through the muscle; these vessels are evaluated to ensure they are a large enough caliber to sew to the chest vessels.
- When the vessel has been evaluated and completely dissected, the flap is completely detached from the body.
- The gluteal incision is closed quickly in multiple layers to provide a strong and secure closure. Time is of the essence as the flap is not currently receiving any oxygenated blood (remember its completely detached from the body).
- As soon as the gluteal incision is closed, the free flap is placed into the chest.
- Using a microscope, the vessels are sewn together very carefully, the anastomosis is checked for patency. The flap will be evaluated to ensure that blood is flowing in and out of this new connection.
- These newly connected vessels are the only blood supply to the flap. Over the next few months new blood vessels will develop to help supply nutrients to the flap.
- Once the flap has been established as viable the breast incisions will be closed. A special monitor will be placed on the flap to evaluate the blood flow to the area, this will remain in place for your entire hospital stay.
- The flap is very vulnerable in the first few days after surgery. ICU care is required to evaluate the flap every 1 hour, if there are changes in the flap such as color change (darkening) & decreased oxygenation on monitor readings, an emergent surgery may be required to re-evaluate the connection between the vessels. Dr. Gupta will be on call after your procedure and can be reached by the ICU nurses at any time in case his evaluation is needed.
- In the ICU the goals will be pain control and monitoring the flap. The abdomen will be sore, and you will need to remain in a flexed position. We will have you evaluated by a physical therapist to ensure you are ambulatory as soon as possible.
- Depending on the appearance and stats of the flap, you will remain in the ICU. Until 3 days post op. It is then safe to decrease the frequency of flap checks to every 4 hours, at this time you will be transferred to an Acute care floor in the hospital.
- You will be discharged 5 days after surgery. All of your post op medications will be sent to your pharmacy. You will go home with the surgical drains in place.
The Incisions
- There will be a diagonal incision along your lower backside.
- There will be another elliptical incision on the breast where the skin from the back will visible.
FAQs
Yes. You will stay in the hospital 5 days, typically 3 days in the ICU.
Yes. The purpose of the DIEP flap is to ensure the newly transplanted tissue survives. No additional breast contouring will be performed at this time as it can compromise the success of the flap.
Yes. 1 drain in the breast and 2 drains in the abdomen. They will stay in place 1-3 weeks depending on the volume of fluid output.
