Summary
Natural tissue breast reconstruction uses a patient’s own tissue to reconstruct a breast. Microsurgery and perforator surgery techniques allow specially trained plastic surgeons to collect small blood vessels in the skin and fat from one part of the body and connect them to blood vessels in the chest. These specialized techniques use an operating microscope to give surgeons the ability to transplant a flap of tissue, called a free flap, from one part of the body to another to create a breast.
Free flaps—like DIEP flaps—allow plastic surgeons to make a new breast from your own living tissue. The success of these procedures relies heavily on the survival of the transplanted tissue, also known as the “flap.” Flap monitoring is a crucial aspect of postoperative care that ensures proper blood supply, reduces complications, and enhances overall surgical success.
During flap monitoring, your team will frequently assess the transplanted tissue’s blood supply to ensure that it is healthy and viable. Since natural tissue relies on reconnected blood vessels, it’s important to know that there are no kinks or clots in those blood vessels to prevent flap loss. Surgeons and medical teams use various monitoring techniques to identify and address issues such as venous congestion or arterial insufficiency. These techniques include observing the color of the flap skin, listening to the blood vessels with a doppler, or placing a probe on the flap’s skin to measure its oxygen content.
Flap monitoring helps to identify flap issues early, should they arise. Early detection facilitates early intervention, which in turn mitigates the risk of flap loss. It is important to know that flap issues and loss are rare complications. Flap monitoring further reduces the already low risk of natural tissue flap loss through early detection.
Flap Monitoring Methods
Clinical Observation
- Skin Color Changes: A healthy flap appears pink and well-perfused, while signs of ischemia (lack of blood flow) include pallor or cyanosis.
- Capillary Refill Time (CRT): Pressing on the flap and observing how quickly the color returns can indicate vascular sufficiency. Rapid refill of a blue flap indicates venous congestion.
- Temperature Assessment: A warm flap is a positive sign, whereas a cool flap may indicate poor perfusion.
Handheld Doppler Ultrasound
This non-invasive tool is used to assess blood flow through the anastomosed vessels. The blood flow is detected by the doppler probe and allows you to hear the flow through the vessels. Arteries and veins produce different sounds and both can be monitored. It provides real-time feedback on the presence and quality of blood flow.
Implantable Doppler Probes
Tissue Oximetry
Benefits of Flap Monitoring
- Flap monitoring is a cornerstone of successful natural tissue breast reconstruction. By employing a combination of clinical assessments and advanced monitoring technologies, surgeons can maximize flap survival rates and patient results. Flap monitoring will continue to offer early signs of flap loss and identify complications.
- It is essential for your team to be able to identify any vascular issue within the flap as early as possible. It facilitates early intervention, which is critical to reducing the risk of flap loss. It is important to know that flap issues and loss are rare complications. Flap monitoring further reduces the already low risk of natural tissue flap loss through early detection.
- There are multiple types of flap monitoring devices available. As always, ask your surgeon for more information on the approach and/or device that will be used after your surgery.
