A simple bedside method for percutaneous femoral vein catheterization allows repeated access to the circulation in patients requiring hemodialysis. Blood is returned into any peripheral vein through a 16-gauge needle. With this technique, one patient was maintained with chronic hemodialysis for eight months, until a more definitive access route could be constructed. Furthermore, the method has been used regularly for acute hemodialysis. Patients requiring chronic dialysis, and in whom conventional vascular access fails, now have an alternative to repeated peritoneal dialysis.
