[Morphology of the lesser circulation during programmed hemodialysis and the transplantation of a human cadaveric kidney].

The results of program-controlled hemodialysis (PCH) and cadaver kidney transplantation (CKT) were evaluated morphologically using 36 sections obtained from patients with end-stage chronic renal failure. For PCH-treated patients the findings indicated development of mixed secondary hypertension of the lungs associated with atherosclerotic involvement of the pulmonary artery and its branches, arteriolar rearrangements and visceral angiosclerosis. Morphologically, a successful CKT outcome resulted in late postoperative (in the time interval of 5 months--4.5 years) reduction of the signs typical for pulmonary vasculature affection with hypertension of the lesser circulation. This can suggest possibility of a reversible course of pulmonary hypertension in relevant patients.
