What complications do you see most often from using Alloderm for breast reconstruction?

Alloderm can lead to rejection and careful attention to your overlying skin may help determine how well the alloderm has integrated into your tissue. Best, Dr. Karamanoukian 

The most common problem I have observed is persistent drainage and redness of the overlying skin which appears inflamed. Other than that, it has accomplished excellent results.

Simply stated, complications from Alloderm are seroma and "red breast syndrome" where the skin may stay more pink than expected for quite some time. These two may be related. A seroma doesn't cause an infection, but a seroma can become infected. Issues such as seromas are becoming less common with modifications to Alloderm, such as perforating it (making holes in it so fluid can't collect into a little puddle in an area of the reconstruction). If you are more worried about specific issues, I would recommend discussing them with your surgeon.

I have been using Alloderm in the breast for both reconstruction and secondary breast augmentation corrections for 15 years, It is a very useful dermal matrix product. I use it primarily in my breast reconstructions as it is quite expensive ,but usually the costs are covered by insurance companies. Alloderm becomes incorporated into your own tissues if it is placed into a proper environment. If the mastectomy flaps are created with great care and there is adequate good supply, the alloderm will become nicely incorporated into your own body. I have had very few infections or complications with alloderm and I use it almost weekly in my practice.

AlloDerm is essentially cadaver skin minus any living cells.  It is used as a scaffold through which a persons living cells can grow into.  It has many uses, but, in use his in breast reconstruction.  AlloDerm does not help in mastectomy recovery.  It does however help in breast reconstruction. In this application, AlloDerm was used to cover the lower portion of an implant that spans from the lower border of the pectoralis muscle to the breast fold.  Because AlloDerm is a foreign substance in can always get infected and as such your doctor and you need to pay close attention to the signs and symptoms.  AlloDerm has also been used in nipple augmentation as well as augmentation of other body parts.  Its efficacy is really not known in these realms because it is not common.  Some providers may use AlloDerm for these applications but please note that its most widespread use is particularly in breast reconstruction as well as repair for abdominal wall hernias.  Please speak with a board certified plastic surgeon if you have any specific concerns regarding your care.
