ENDURAGen graft durability in α-Gal disease.
We present a case of eyelid reconstruction using ENDURAGen, a porcine-derived acellular collagen graft, complicated by dissolution of the graft in a patient recently diagnosed with α-Gal disease. A 33-year-old female status post enucleation of the left eye at age 7 struggling with malposition of her prosthesis due to lower lid retraction and laxity underwent eyelid reconstruction with ENDURAGen. She did well post-operatively for 9 months, but then began having issues with prosthesis dislodgement and rotation. Around that time, the patient was diagnosed with α-Gal disease. Repeat eyelid reconstruction was performed, this time with an ear cartilage graft, and dissolution of the original ENDURAGen graft was confirmed. This case highlights the need for evaluation of the durability of ENDURAGen in patients with α-Gal and for caution in choosing porcine or bovine-derived implants for tissue reconstruction in this population.
