[Embolization of non-functioning renal allograft: efficacy and control of systemic inflammation].
BACKGROUND
The graft intolerance syndrome (fever, pain, haematuria) may lead to a chronic inflammatory disease, with cardiovascular repercussion. Nephrectomy is considered the classical treatment of these cases but nowadays renal vascular embolization has been suggested as a possible alternative treatment. The present study concerns seven cases trated with renal vascular embolization in our hospital summarizing data of graft intolerance syndrome and the chronic inflammatory disease.


METHODS
Between january 2000 and december 2003 seven renal vascular embolization were performed in nonfunctioning renal allograft. The procedure was made with calibrated particles of 300-500micron. Data about complications related to the technique the same as analitic inflammatory parameters before and after treatment (CRP, ferritin, serum albumin, hemoglobin, erythropoietin) were registered.


RESULTS
The patients were two men and five women, with median age of 39,7 +/- 8,8 years. The period beween the dialysis and the embolization was of 10,0 +/-8,2 months. Comparing the perion of admission in the hospital due to nephrectomy which was of 17,86+/-4,41 days, the period because of embolization was shorter, being 8,14 +/- 4,53 days. All analitic parameters studied, clearly improved after embolization with decrease of ferritin and CRP, increase of albumin and better hemoglobin level with lower erythropoietin dose. In five of the seven patients there was no renal captation with CT or gammagraphy. Four patients presented a postembolization syndrome, but no other important complication was registered. Neither reembolization nor renal nephrectomy was neccesary in any of the seven cases.


CONCLUSIONS
Percutaneous renal embolization is a simple, easy, safety and effective technique that must be considered as an alternative treatment to nephrectomy, resolving the chronic inflammatory disease secondary to the graft intolerance syndrome.
