Ruptured brachial artery aneurysm in a patient with type 1 neurofibromatosis.

Vascular lesions associated with neurofibromatosis type 1 (NF1) are rare but can lead to catastrophic complications if disrupted. Ruptured aneurysms in NF1 patients are difficult to treat surgically because of vascular wall fragility. We describe a female NF1 patient with a ruptured aneurysm of her brachial artery. This is the first published case of successful reconstruction of a ruptured brachial aneurysm associated with NF1, using a saphenous vein graft.
