[Venous bypass in situ]. / Venózny bypass in situ.

The authors report on their experience with venous bypass in situ performed in 54 patients. For disruption of venous valves they constructed a simple stripper of the Connolly type. The method of bypass in situ is described in detail and its advantages are discussed. For reconstructive operations below the knee the bypass in situ should be preferred over the conventional reversed graft.

[Sealing of ultraporous vascular prostheses with autologous fibrinogen]. / Utesnovanie ultrapórovitých cievnych protéz autológnym fibrinogénom.

After their long lasting experience with commercially prepared fibrinogen for sealing off ultraporous vascular prostheses, the authors have introduced the use of freshly prepared fibrinogen from the patient's own blood. This approach provides an additional advantage by allowing to substitute the blood losses at the operation with shelfed autologous blood. The preparation of autologous fibrinogen is described and the advantages of its use are discussed.

[Results of using high porosity aortofemoral bifurcation prostheses]. / Výsledky pouzitia ultrapórovitých aortofemorálnych bifurkacných protéz.

The authors report on their four-year experience with the use of extremely highly porous vascular polyester prostheses of Czechoslovak proveniencè, whose wall was sealed with fibrin. Aortofemoral bifurcated prostheses with a permeability of 6 100 ml/cm2/min were implanted in 102 patients. The method of fibrination appears to be simple and safe. No hemorrhage through the prosthetic wall was observed. The authors expect the high porosity of the prostheses to result in longer lasting patency of the grafts and thus in improvement of long-term results.
