RESUMEN
The authors present a 5-year experience in formation of the arterio-venous fistulas for hemodialysis. Analysed material includes 58 fistulas in 40 patients. Fistulas were formed twice or more times in 22% of the patients. Thrombus in the fistula was the most frequent complication (10.3%). The authors form arterio-venous fistula "of choice" in the peripheral portion of the forearm anastomosing radial artery with cephalic vein "side-to-end". Such a procedure in other portions of the arm is related to a higher risk of failure. Intra-arterial subtraction angiography is of significant help in the selection of the tactics of secondary operations forming fistula.

In 24 patients with simple glaucoma in whom the IOP did not normalize under the conservative treatment the authors checked--between others--the Po, the outflow coefficient (C) and calculated Po/C. Laser trabeculoplasty was performed subsequently. The enumerated indexes were examined the day after surgery, then after the 1-st and 2-nd week, after a month and 2 months. In the majority of cases the coefficient C showed an improvement and normalization of the IOP distinctly seen till the 1-st month after operation. In subsequent observations 5 persons showed a renewed deterioration of the hydrodynamic conditions and the intervention was repeated leading to an improvement in 3 cases. In consideration of the lack of normalization of the IOP in 2 persons it was necessary to subject them to a surgical procedure.
