The efficacy and complications of 30 cuffed, double-lumen silastic catheter
s (Permcaths) inserted in 24 patients with chronic end-stage renal failure
were studied prospectively at the Security Forces Hospital in Riyadh from J
une 1992 until March 1996. The causes of end-stage renal failure in the 24
patients were diabetes mellitus (10), glomerulonephritis (5), hypertension
(2), amyloidosis (1), and bilateral small kidneys of unknown cause (6). Loc
al anesthesia was used in 27 and general anesthesia in 3 patients. Internal
jugular, external jugular, and subclavian veins were used in 13, 12, and 5
instances, respectively. The number of dialysis sessions varied from 1 to
292, with a mean of 59 +/- 60 sessions. The blood flow was 200 to 350 (280
+/- 42) mL/minute. The duration of catheter function varied from 4 to 682 (
150 +/- 160) days. Six catheters developed poor blood flow due to thrombosi
s in one of the two lumens. In two, blood flow improved after use of strept
okinase 15000 IU/lumen, and four had to be changed. Four patients developed
exit-site infection. Staphylococcus aureus was isolated from three of thes
e patients, and all of them improved with systemic antibiotics and local dr
essing. Acinetobacter was isolated from one exit site and the catheter was
changed because there was no response to antibiotics. Four patients develop
ed septicemia; S. aureus was isolated from two, Acinetobacter from one, and
one had negative culture. Catheters were removed in two of these patients
because there was no response to antibiotic therapy. One patient developed
right internal jugular vein thrombosis. The reasons for removal of a Permca
th were: poor blood flow (4), death of the patient (3), bleeding and hemato
ma (2), renal transplantation (2), septicemia (2), exit-site infection (1),
use of arteriovenous fistula (1), patient's request (1), and primary failu
re (1). Eleven catheters were functioning until the end of the study. Two p
atients were lost for follow-up.
In conclusion, Permcath can be used as a temporary as well as a long-term v
ascular access. It combines the advantages of being able to be used immedia
tely and for an indefinite period that varies from weeks to months.
