Abstract
In von Recklinghausen's disease vascular involvement is rare, especially rupture of peripheral arterial aneurysms. A 65-year-old man with previously diagnosed neurofibromatosis was admitted because of left lateral neck and left shoulder pain. Computed tomography and selective left subclavian angiography revealed ruptured aneurysm of left costocervical artery, and therefore an emergency operation was performed. Left costocervical artery was exposed and proximal ligation of the aneurysm was performed. Angiography is a most useful and important procedure in operations for vascular involvement in von Recklinghausen's disease.
