[Compressive false aneurysm of the brachial artery in a hemodialysis patient: Always superficialize the basilic vein of the arm!].

The creation and preservation of vascular accesses, in patients with end-stage renal failure, remains a challenge for nephrologists and vascular surgeons. Native fistula is the best vascular access, humeral-basilic fistula is a precious access in patients who have exhausted their venous capital in the forearm and in whom the cephalic vein of the arm is small or damaged. Given its deep location, any puncture of this vein is prohibited before its superficialization, even if it is of good caliber, because it can have dramatic consequences, in particular the loss of the limb or even death. We report the case of a patient undergoing hemodialysis for seven years with a non-superficialized humeral-basilic fistula, admitted for an iatrogenic false aneurysm of the brachial artery following a puncture for dialysis, with compression of the median nerve, treated surgically.
