title: Rare complication of massive hemorrhage in neurofibromatosis with arteriovenous malformation.
abstract: Neurofibromatosis is rare in the general population. Its clinical manifestations are systemic and variable. The clinical presentation of cutaneous lesions is even more variable. Some patients have giant tumors in the trunk or limbs (so-called "elephant neurofibromatosis"). The pathological findings are diffuse neurofibromatosis of the nerve trunk associated with overgrowth of subcutaneous tissue and skin. The associated vascular malformations make most surgeons hesitant to address them because bleeding to death is possible if the bleeding is not well controlled. According to the authors' experience in treating this complication of neurofibromatosis, they noted that there are three key points to reducing the amount of hemorrhage to a minimal level: (1) hypotensive anesthesia, (2) preliminary sutures around the lesion, (3) ligation of the limited numbers of feeding vessels in the vascular malformation of the neurofibroma. Ligating these pedicles can decrease bleeding during resection of the neurofibroma, as demonstrated in their patient.
