Hi i have got factor 11 deficiency and would like to have a breast enlargement would this be possible?

Probably: The factor 11 deficiency is definitely an extra risk factor that ultimately may or may not be worth taking. You should consult with your medical doctor or hematologist about the extra risk involved with surgery and what measures can be taken to reduce them. If you decide to proceed, make sure that your plastic surgeon and your doctor communicate to share information about your factor deficiency.

Possible with prep: You may need to determine how low your factor is and may need blood products to help raise the level to one that is safe for surgery. The trick is in learning what the risk of the transfusions will be considering the breast surgery would be cosmetic and not urgent or emergent. Is the risk of the preparation worth the added risk of the operation in an elective setting?

Possible w/ caution: The article below: http://www.Ncbi.Nlm.Nih.Gov/pubmed/10541197 is an excellent article discussing the difference between high and low risk patients with factor xi deficiency. Low risk is higher than 15% or between 4-15% and history of multiple surgeries without complications. If you are high risk, you may want to reconsider or plan on transfusion in a major hospital setting.
