ABSTRACT
In this report we have discussed our experience with a special home-made platelet-rich plasma (PRP)-fibrin glue (FG) as a last resort for treatment of a challenging case of postoperative CA. A 25 years old, ill woman was admitted with severe ascites and hepatic encephalopathy in our center. She was a known case of autoimmune hepatitis and cirrhosis who had undergone liver transplantation 5 years ago and developed chronic rejection. During the surgery an old organized thrombosis in the portal vein was detected, accordingly an iliac vein graft was used to bypass the superior mesenteric vein. After surgery the patient developed chylous ascites. Having no other choice, based on our experience with PRP-FG in similar situations, we decided to use this method as a last resort to treat postoperative chylous ascites. It can be concluded that when conservative management is not working for the treatment of postoperative chylous ascites in intractable cases, PRP-FG can be considered as a last resort treatment. A special home-made PRP-FG was prepared for the patient and of that, 90 mL was injected to the abdominal cavity via the drainage tube followed by a 25 mL of isotonic saline solution to prevent clot formation within the tube. Few days after treatment, chylous secretion decreased and then completely ceased. It can be concluded that when conservative management is not working for the treatment of postoperative chylous ascites in intractable cases, PRP-FG can be considered as a last resort treatment.
ABSTRACT
The amount of newborn blood that can be collected from a single cord donor is limited, but a significant amount remains in the placenta. We used a simplified perfusion method to collect this additional blood. Umbilical cord blood from 15 newborns was collected before placental delivery by umbilical vein puncture. After delivery, the placenta was placed on sterile gauze and 63 mL of citrate-phosphate-dextrose-adenine anticoagulant were injected into the umbilical vein that was then clamped near the placenta. The placenta was gently massaged, hung over a sterile vessel, and the umbilical cord cut sterilely near the embryonic surface. Additional blood was collected into the sterile vessel by pressuring a gauze bag around the placenta. We assessed the contribution of this second fraction to the total volume, total nucleated cell (NC), CD34+, hematopoietic progenitors cell, and colony forming unit count and bacterial contamination risk. The total collected volume was 127.3 mL (range 92-170) and the NC content was 1.6+/-0.73x10(9). The mean second fraction contribution from 15 units to the total nucleated and mononuclear cell content was 54+/-9.87% and 54+/-9.52%, respectively. The added percentage of CD34+ and hematopoietic progenitor cells was 54.3+/-10.35% and 46.7+/-11.5%, respectively, while the additional percentages of colony forming-granulocyte macrophage and colony forming-erythroid in the second fraction were 43.2+/-5.5% and 39.8+/-4.3%, respectively, indicating that the cells collected after placental perfusion (second fraction) had similar HPC content and in vitro hematopoietic potential. The method did not increase the risk of bacterial contamination.
