Introduction: In patients with end stage renal disease when there is inability for the creation of a direct arterio-venous fistula or by using a graft, the insertion of a permanent hemodialysis catheter in a central vein ensures the conduction of hemodialysis. We present a technique of placing a permanent catheter in the inferior vena cava through the great saphenous vein without the use of a guide wire. Patients and Methods: Over the study period, 12 hemodialyzed patients, with a mean age of 73 years, were referred for placement of a dialysis catheter through the great saphenous veins. The procedure was performed under local anesthesia, ECG monitoring, and fluoroscopic control. The insertion of the tunneled hemodialysis catheters was accomplished with ease, through surgical exposure of the great saphenous vein, without the need for a guidewire. Results: The hemodialysis catheter's function was assessed intraoperatively. No intraoperative or immediate post operative complications were noted while during the study period 3 thromboses and an infection were detected (0,95 per 1000 catheter days). The primary catheter patency rates were 92%, 84%, 54% at 30, 90 and 180 days respectively, varying from 28 to 845 days (mean±SD = 294 ± 243,3). Conclusion: The introduction of dialysis catheters in the inferior vena cava through the great saphenous vein is technically simple with rare complications and with higher patency rates compared to the traditional femoral approach. © 2012 Wichtig Editore.

Objective: To examine whether factors in a child's perinatal history influence renal function in adolescence, using a cross-sectional study, as during the past two decades researchers have tried to ascertain whether factors such as low birth weight might be related to a decline in kidney function in adolescence, although published data for children born with vesico-ureteric reflux (VUR) remain insufficient. Patients and methods: Sixty-one children (20 boys and 41 girls), born between 1985 and 1989 in Greece and diagnosed with VUR, were assessed. A detailed personal and family history was taken and basic anthropometric variables were measured. Kidney function was calculated from serum creatinine levels, and the glomerular filtration rate (GFR), fractional excretion of sodium, albumin levels in urine, creatinine clearance, cystatin C level and the dimensions of each kidney were measured. Results: The results showed a positive relationship of birth weight (P = 0.01) with blood pressure in adolescence in children diagnosed with any degree of VUR. Renal function seemed to be intact whatever the cause of VUR, the volume of the kidneys in adolescence (P = 0.386 and 0.483, respectively, for the right and left kidney) and the values of GFR (P = 0.105), creatinine clearance (P = 0.213) and cystatin C (P = 0.055). Conclusions: These results showed that although there is a positive association between blood pressure in adolescence and birth weight, in children born with VUR there was no deterioration in renal function. Kidneys seem to function normally regardless of the gestational age at birth. © 2014.
