External iliac vein stenosis after segmental pancreatic transplantation: treatment by percutaneous endoprosthesis.

A stenosis of the iliac vein secondary to a fluid collection in a pancreas transplant was identified by color Doppler flow sonography. The pancreatic venous drainage was reversed to the contralateral iliac veins via venous collaterals. After two unsuccessful angioplasties of the vein stenosis, a Wallstent was positioned above the venous anastomosis, and has remained patent for 8 months. The pancreatic venous drainage became normal after the procedure.

[Nyctohemeral variations of cyclosporine administered orally in renal transplant patients].

The circadian intraindividual variations of cyclosporin blood concentrations were studied in nine renal transplant patients at steady state. The cyclosporin was administrated orally twice a day (9 a.m. and 21 p.m.). Blood concentrations were analysed by H.P.L.C. AUC = area under the drug concentration versus time curve, Cmax = maximum blood concentration, Cmin = minimum blood concentration, Tmax = Time to maximum concentration. Statistical analysis (t, Wilcoxon) shows: AUC, Cmax and Tmax are not significantly modified, Cmin (21) less than Cmin (9) (p less than 0.02). This phenomenon seems to be rather a cyclosporin metabolism variation than an absorption alteration.

[Surgical results of renal transplantation (62 cases) (author's transl)].

Over a period of 16 months, 62 renal transplantations were carried out by the same medicosurgical team. The follow-up period being 3 months for the most recent cases, 57 patients are still alive and 44 grafts are functional. No surgical complication was the cause of loss of a graft and even less so that of a transplanted patient. Reestablishment of urinary continuity was carried out by ureteroneosystostomy and no fistula or ureteral stenosis was noted. Only 5 vesical fistulae were related to this technique but they healed with no problem. Parietal infectious complications (32%) were much more preoccupying, and frequently the very cause of the majority of urinary complications. Finally vascular stenosis, found in a little more than 6 p. 100 of cases only lead to surgical restoration on one occasion. These different results are compared with those of other teams published today.
