title: A double-lumen subclavian cannula (DLSC) for temporary hemodialysis access.
abstract: Vascular access with an indwelling subclavian cannula is now being widely used as an alternative to silastic-teflon shunts or femoral cannulation in patients with end-stage renal failure who are temporarily lacking an arteriovenous fistula. Advantages are the preservation of blood vessels and the avoidance of repeated vein puncture for each dialysis. The only disadvantage of the standard single-lumen subclavian cannula is the need to use a single needle machine. This is an encumbrance especially in the management of acute renal failure. We have developed a double-lumen subclavian cannula which, having 2 blood pathways, does not require the use of a single needle machine. This device function well for temporary vascular access in patients with terminal renal failure who are awaiting AV fistula construction or repair. It is also especially convenient in the management of acute renal failure when there are difficulties in the construction of a shunt.
