5 YEARS EXPERIENCE WITH THE QUINTON PERMCATH FOR VASCULAR ACCESS

Over a five-year period 64 Quinton Permcaths were inserted into 51 dialysis patients (age range 17-72 years, mean 52.1 SD 12.83). The duration of catheter use ranged from 5 to 1479 days, mean 315.7 SD 337. The actuarial catheter survival rate at 1 year was 74%, at 2 years 43%, at 3 years 25% and at 4 years 12%. The indications for use were: exhausted peripheral access; CAPD contraindicated; abrupt failure or lack of an arteriovenous fistula; acute renal failure; limited life expectancy; patient insistence; conventional access contraindicated. Only minor complications occurred during insertion: haemorrhage requiring exploration in three patients and a temporary left recurrent laryngeal nerve palsy in one patient. The exit site infection and septicaemia rates were 4.95 and 3.36 per 1000 catheter days respectively. Eighteen catheters failed due to infection (range of use 72-1479 days, mean 559 SD 388). Inadequate initial blood flow (< 150 ml/min) occurred in 10% of dialyses but only six catheters failed due to intractable flow difficulties (range of use 5-49 days, mean 22 SD 17.5). Catheter sepsis was implicated in the death of two patients. One subclavan/innominate vein thrombosis occurred. The Quinton Permcath represents a significant advance providing immediate, durable, and relatively safe access in a variety of difficult circumstances.
