[Arteriovenous fistula complicated by "fat arm" caused by proximal venous occlusion--salvage by axillo-jugular crossing bypass].

Although subclavian vein cannulation is more and more avoided for temporary angioaccess in hemodialysis patients may still now present stenosis or thrombosis of this catheterized central vein. Complications may appear, sometimes severe, after creation of an ipsilateral arteriovenous fistula. It is important to treat them but also to conserve the new created vascular access, in order to maintain these patients as long as possible on hemodialysis treatment. According to the circumstances, different procedures are used, and among them, the axillary-contralateral internal jugular vein crossing bypass as here reported.
