Our Summary
This research paper reviews the use of a special kind of transplant surgery, called vascularized composite allotransplantation, in treating burn victims. This method has been used since 2003, but there have been concerns about its safety due to the high risk of the body rejecting the transplanted tissue.
The researchers looked at data from January 2000 to September 2019. They included studies which used this type of transplant for burn victims and excluded those that didn’t report the results. After analyzing the data, they found that 152 of these transplants were performed on 117 patients, including 45 face transplants and 107 extremity transplants. About 22% of these surgeries were performed on burn victims.
Unfortunately, the results showed that the patients who underwent this surgery for burn reconstruction had a higher death rate within the first year (12% compared to 1.1%) and there were also more cases of the body rejecting the transplanted tissue. Most of the patients who died had received three or more transplants at the same time.
The researchers concluded that this type of transplant surgery carries a higher risk for burn victims, with a greater chance of death within the first year and nearly double the risk of tissue rejection. They suggest that future studies should look at the specific risk factors for burn victims and investigate the relationship between the amount of transplanted tissue and the success of the surgery.

Doctor’s Tip
A doctor might tell a patient considering vascularized composite allotransplantation for burn reconstruction to carefully weigh the risks and benefits of the surgery. They may advise the patient to discuss their individual risk factors with their medical team and to consider the possibility of needing multiple transplants. It’s important for patients to have realistic expectations and to understand the potential complications involved in this type of surgery. Additionally, close monitoring and follow-up care are essential to ensure the best possible outcome.
Suitable For
Patients who are typically recommended vascularized composite allotransplantation include those who have suffered severe facial disfigurement or extremity loss from burns, trauma, or congenital defects. These patients may have exhausted other reconstructive options and have a strong desire to improve their quality of life and regain function. Additionally, patients who have a good support system and are willing to adhere to a strict medication regimen to prevent rejection are also good candidates for this type of surgery. However, it is important to note that this type of transplant surgery carries a higher risk for certain patient populations, such as burn victims, as shown in the research paper discussed above.
Timeline
Before vascularized composite allotransplantation:
- Patient suffers severe burns that cannot be effectively treated with traditional methods
- Patient undergoes evaluation by a medical team to determine if they are a candidate for vascularized composite allotransplantation
- Patient undergoes extensive testing to assess their overall health and suitability for surgery
- Patient is placed on a waiting list for a suitable donor match
- Patient undergoes preoperative counseling and education about the risks and benefits of the surgery
After vascularized composite allotransplantation:
- Patient undergoes the transplant surgery, which involves replacing the damaged tissue with healthy tissue from a donor
- Patient is closely monitored in the intensive care unit immediately after surgery
- Patient undergoes a period of rehabilitation and physical therapy to regain function in the transplanted area
- Patient takes immunosuppressive medications to prevent rejection of the transplanted tissue
- Patient undergoes regular follow-up appointments and monitoring for signs of rejection or complications
- Patient may experience improvements in function and appearance of the transplanted area, but also faces the risk of rejection and complications in the long term.
