After the collection of the stem cells, the patient will be submitted to puncture the femoral artery using the Seldinger technique under local anesthesia, followed by catheterization of the ostium of the renal arteries with minimum use of nonionic iodinated contrast. With the routing of diagnostic catheter or guide, the solution numbering about 30 to 100 million of dissolved plasma cells will be divided and injected into two renal arteries. The infusion volume is about 5 ml in each kidney. Whole body and planar scans will be performed 2 and 24h after infusion to determine the migration and cell viability. The patient will remain hospitalized for more 48 hours for clinical monitoring and collection of laboratorial tests.
