RESUMEN
The authors present their own comments on the effect of Warren shunt on hypersplenism. Hypersplenism is frequent complication in portal hypertension. The authors estimate its frequency on 64.7% of patients. Spleen size, thrombocyte count, WBC count, and esophageal endoscopy have been carried out prior to and following distal spleno-renal shunt. Surgery produced favourable effect in 70% of patients, i.e. a decrease of hypersplenism symptoms. An increase in blood platelet count may serve as a screening marker of anastomosis patency.

The results of the surgical treatment of 115 patients with the abdominal aortal aneurysms are presented. Indications to surgery depending on the stage of aneurysm, way of classification, and coexisting cardiological disorders have been discussed. Excellent and favorable results of surgery have been achieved in 70 patients (60.9%). Overall hospital mortality rate was 39.1%. Out of patients who underwent elective surgery 11.6% died, in the group operated urgently--43.3%, and in emergency situation 89.4% of the operated patients died. Percentage of patients with coexisting cardiological disorders amounted to 54%, 62%, and 80% respectively. A strict correlation of the results of surgery and duration of the disease, and consequently classification to the treatment, has been noted. Indications to the elective surgery are related to the size of aneurysm, rate of its enlargement, patient's age, and general health.

The experiments were performed on nine mongrel dogs. The authors used straight crenated grafts of diameters 6 and 12 mm. In 6 dogs were implanted into abdominal aorta below an origin of renal arteries and above its bifurcation. Autopsy was performed after 49, 62, 98 days. The authors evaluated the implant examining it with two methods: macroscopic and histopathologic. In addition were 6 experiments made with three dogs. The grafts were placed extracorporealy between canulated artery and femoral vein. The authors measured the volume of transudated blood, the time of transudation and degree of grafts flexibility marked by the alongation. In was stated that tested double veloured grafts of Polish production are softer and more flexible than those produced so far. The edges of the tested grafts have higher shred resistance during the sewing procedure. Their more regular texture results in smaller degree of transudation: after initial typical preclotting the grafts "sweat" evenly and quickly stops the transudation. In authors opinion the grafts should be clinically evaluated in treatment of peripheral blood vessels diseases.
