Moreover, little information on the management of this easily recurring disease is available at present. We describe the first case of a Chinese liver transplant recipient with PVB19-induced PRCA during immunosuppressive therapy. The patient suffered from progressive anemia with the lowest hemoglobin level of 21 g/L. Bone marrow biopsy showed selectively inhibited erythropoiesis with giant pronormoblasts. Detection of PVB19-DNA in serum with quantitative polymerase chain reaction （PCR） revealed a high level of viral load. After 2 courses of intravenous immunoglobulin （IVIG） therapy, bone marrow erythropoiesis recovered with his hemoglobin level increased to 123 g/L. He had a lowlevel PVB19 load for a 5-too follow-up period without recurrence of PRCA, and finally the virus was cleared. Our case indicates that clearance of PVB19 by IVIG in transplant recipients might be delayed after recovery of anemia.展开更多

We described our experiences in 10 children patients who were accepted for transcatheter closure of CAF. Methods Ten children were 3-10 years old （seven males） with CAF who underwent percutaneous transcatheter closure between October 1995 and April 2008. Sites of origin of these fistulas were： right coronary artery in seven, left anterior descending coronary artery in two, and left circumflex coronary artery in one patient. Drainage sites of these fistulas were： right atrium in seven, right ventricle in two and left ventricle in one patient. All of these fistulas were congenital and had only one orificium fistula.Results A Cook coil was used in four patients and an Amplatzer patent ductus arteriosus （PDA） occluder was used in six patients. Checking the angiogram after the procedure revealed complete occlusion in nine patients （90%） and minimal residual flow in one （10%） patient. Technical success was achieved in all patients. Follow-up studies at short term showed complete abolition of shunt in all patients with no evidence of recanalization leading to recurrence of shunt. Conclusions Transcatheter therapy using either Cook coil or Amplatzer PDA occluder is suggested to be a safe and effective method of occlusion. The midterm outcome of the intervention for CAF is satisfactory.展开更多

However, this modality still encounters significant complications during the procedure and/or follow-up. The covered Cheatham-Platinum （CP） stent commonly used to be chosen as a rescue treatment in these patients. The purpose of this study was to evaluate the use of covered CP stent as the primary modality in the treatment for native CoA. Methods Twenty-five covered CP stents and 2 bare CP stents were implanted in 25 patients with native CoA. All patients after the intervention were invited for follow-up examinations. Results The peak systolic gradient across the lesion decreased significantly from a median value of 67.5 mmHg （quartile range, 19.3 mmHg） to 2 mmHg （quartile range, 4.0 mmHg） （P 〈0.0001）. Stenotic segment diameter increased from a median value of 5.0 mm （quartile range, 1.5 mm） to 17.9 mm （quartile range, 2.5 mm） （P 〈0.0001）. The median ratio of diameter of the coarctation postprocedure to preprocedure was 4.2 （quartile range, 1.6）. All of the CP stents were placed in the suitable position without any acute complications. During a follow-up period of up to 72 months, no complications were encountered. Most of the patients （21/25） were normotensive, apart from four patients requiring antihypertensive medication during the follow-up. Conclusion The implantation of covered CP stent as the primary modality is safe and effective in the treatment for native CoA in adolescents and adults.展开更多
