Regional trans-scrotal antegrade venotesticulophlebography was used to study elements of renocaval anastomosis in 154 males suffering from varicocele. In 153 patients varicocele was caused by renal vein obstruction and hypertension, in 1 patient it resulted from iliac vein aneurysm obstructive for pelvic veins. In cases of renal vein obstruction on the left all the venous blood runs from the kidney along the testicular vein to the pampiniform plexus flowing further to the system of the iliac veins. Ligation or endovascular embolization of the testicular vein aggravates renal venous hypertension, but varicocele collapsed. The authors suggest discussion on methods of varicocele treatment.

In 124 patients with different forms of chronic neurotoxoplasmosis there was an increased tone of brain vessels without signs of a drop in the pulse blood repletion in the arteries of carotid and vertebro-basillar basins. There was also a decrease of the pulse blood repletion in the extremities (mainly in the lower) with a normal or insigficant increase of the tone in the vascular wall. A normalization of the rheographic curves in pharmacological tests and during treatment indicate a functional character of these changes in most of the cases.
