Production of platelet concentrates (PCs) have an important role in the replacement therapy for severe thrombocytopenic conditions. PCs can be prepared by centrifugal technique which have two main methods: platelet rich plasma and buffy coat. We studied on 40 blood units (volume 450 ml, anticoagulant: CPD-A1, triple bags-type) and evaluated the yield of platelet (PLT) separation red blood cell (RBC) and white blood cell (WBC) contamination from these methods. The result show that the yield of PLT separation from PRP method is significantly higher than those from BC (82.60+ 7.20x1010, yield: 56.75% vs 50.59 + 2.97 yield: 32.4%) The WBC and RBC’s contamination in PCs from two methods are higher than the standard of Council of Europe. By sum up, follow studies will be necessary for decreasing the WBC and RPC’s contamination in PCs, the PRP method may be evaluated as a high-yield method in PCs production

From Aug-2000 to Aug-2003 at HCM City Blood Transfusion and Hematology hospital, 31 cases of endoscopic splenectomy were studied to evaluate the effect of this surgery to treat chronical immuno-thrombocytopenic purpurea once corticotherapy and immunosupressive therapy failed. Results showed that one year after splenectomy, 64,52 – 76,92%, and 2 years after, 50% of cases had had completely positive response. There was absolute failure in 38,7% of cases within 3 first months, but from the 4th month, there was no relapse case. A half number of patients with failed splenectomy had had quick response to corticotherapy more.The duration of treatment was short, endoscopic splenectomy was safe. There was no death. No case of blood transfusion was needed. There were no complications

The authors present a study on the pathological features of 45 spleens which were splenectomised by immune thrombocytopenic purpura (TTP) from 1/1/1990 to 31/12/1997 at Viet Duc hospital, 43/45 were women, age from 12 to 50, in which 35/45 were under 30 ages. Weight and sexe of these spleens were observed. They are in normal size or rather enlarged, but their weight are hyperplasis, but no sclerosis and nomalignacy: neutrophils, eosinophils, macrophages and sometimes megakaryocytes may be found in the red
