RESUMEN
The investigation has shown that patients with the diagnosed abdominal aortic aneurysms must be operated, the age being not considered a contraindication to surgical treatment. Five years survival of the patients after resection of the abdominal aortic aneurysm and its prosthesis does not depend on the age and is higher than 70%, while the expectant management leads to rupture of the aneurysm and death of 70% of the patients. A medical algorithm has been developed allowing reduction of lethality of elderly patients with abdominal aortic aneurysms and less frequency of complications.

In 1996-1998 131 patients were observed who underwent semiclosed loop endarterectomy of the aorto-femoral segment by Vollmar loops. The control group consisted of 220 patients on whom the operations of uni- or bilateral aorto-femoral bypass with synthetic prostheses were made. The semiclosed loop endarterectomy was mainly fulfilled through the femoral access, the retroperitoneal access was used in 18.3% of the patients. Thus the time of operation was as short as (100 +/- 10.9) min. in mono- and (118.6 +/- 12.9) min. in bilateral reconstructions, and blood loss in typical cases was not more than (327 +/- 24.1) ml. The operation of semiclosed loop endarterectomy gave a high level of patency to the reconstructed aorto-femoral segment. The primary 5-year patency of the iliac arteries was 91.86%, the cumulative one--93.87%. Such parameters for shunting operations were lower: 75.4 and 81.63% respectively (p < 0.05).

The authors studied the changes in the mass and contractile function of the myocardium in 24 patients with vasorenal hypertension before operation and in the late periods after surgical correction of the renal blood flow. It was found that in vasorenal hypertension the mass of the myocardium doubled while its contractile and pumping functions diminished. In the late periods after adequate surgical correction of renal blood flow with a good hypotensive effect hypertrophy of the myocardium regresses and its contractile function improves.
