Successful revascularization using a saphenous vein for a ruptured brachial artery aneurysm in a patient with neurofibromatosis type I.

ABSTRACT

Vasculopathy in patients with type 1 neurofibromatosis is known. Brachial artery aneurysms in patients with type 1 neurofibromatosis are rare, but any rupture can be extremely serious. A 56-year-old woman presented to our hospital with sudden pain in her right upper arm. Computed tomography revealed a ruptured brachial artery aneurysm, and operative reconstruction using a saphenous vein graft was performed. This is one of the few case reports of such successful revascularization using saphenous vein. The pathologic findings suggest neurogenic tumor invasion, and end-to-side anastomosis was effective in avoiding hemorrhagic complications.
