Background AIDS (acquired immune deficiency syndrome) has become the most devastating disease which humankind has ever encountered. Human immune-deficiency virus (HIV) is transmitted through blood, sexual behavior and mother-to-baby, with more efficient transmission through blood transfusion. HIV risk among blood transfusion was severe due to lack of effective and correctly applied screening method and rigorous management, especially in some developing countries. Since the first HIV screening reagent was approved by FDA to screen the blood in 1985, the fourth generation test has been produced till now. Initially, HIV test was primarily used to screen the blood supply, it also became an important aspect of HIV prevention, especially screening among people donating blood. Today, HIV testing is seen as an integral part of both the nation’s prevention and treatment efforts. Objective To assess the effectiveness of any intervention tests for HIV screening among people donating blood, and find appropriate tests for HIV screening to decrease the risk of HIV transmission by blood transfusion. Search strategy MEDLINE, Cochrane Controlled Trials Register (CENTRAL/CCTR), AIDSLINE, EMBASE, CBM were be searched with the terms: "HIV", "AIDS", "screening", "test", "blood donor", "blood bank" and the detailed screening method. The websites of WHO, UNAIDS, CDC, FDA, and their related links were searched. Letters were mailed to various agencies and experts in this field to acquire unpublished reports. Inclusion criteria RCT and CCT for screening HIV among blood. donors will be included. Observational studies such as cohort studies, cased-control studies, and historical controlled studies will be used for sensitivity analysis. Method of the review According to the principles of Cochrane Review, selection of trials for inclusion, quality assessment of studies, data extraction and syntheses were conducted by reviewers.
【Abstract】ObjectiveTo report the author’s experience with the first case of an adult-to-adult living donor liver transplantation (LDLT) for Budd-Chiari syndrome (BCS) using cryopreserved vena cava graft in postheptic vena cava reconstruction. MethodsA 35-year-old male patient with a diagnosis of BCS complicated with inferior vena cava (IVC) obstruction received medical treatment and radiologic intervention for nine months, no relief of the symptoms could be achieved. Finally, the patient underwent LDLT, which required posthepatic vena cava reconstructed using cryopreserved vena cava graft. ResultsThe patient has had an uneventful course since the LDLT. ConclusionWe believe that LDLT combined with posthepatic IVC reconstruction using cryopreserved vena cava graft is considered to be a sound modality for IVC obstructed BCS.
【Abstract】Objective To review the recent advances in the use of marginal liver in liver transplantation. Methods The literatures of recent years on the use of marginal liver for liver transplantation were reviewed and summarized.Results The donors with older age, hemodynamic instability, long stay in the intensive care unit and fatty liver are significantly clinical marginal liver donors.Conclusion Though the use of marginal liver donors negatively influences the results of liver transplantation, marginal liver expands the liver source for liver transplantation with a good result.
Objective To investigate the clinical choice on graft size and the type of donor’s hepatectomy in adult living related partial liver transplantation. Methods The literatures in recent years on the donor’s evaluation, the size of liver grafts, the types of donor hepatectomy and safety of donor in adult living related partial liver transplantation were reviewed.Results The size of liver graft is a crucial factor related to the safety of donor and the prognosis of the recipient. GW/ESLW≥30%, GW/BW≥0.8% may be the lowest limits. Left lobe contained middle hepatic vein, extended left lobe with leftside caudle lobe, right lobe or extended right lobe contained middle hepatic vein may be the practical choice.Conclusion It is important to make a reasonable choice of liver graft according to the estimation of GW/ESLW or GW/BW, and the anatomy of liver in adult living related partial liver transplantation.
ObjectiveTo evaluate and summarize the perioperative management experience of living related liver transplantation (LRLT). MethodsA retrospective analysis was made in perioperative management of 13 cases undergoing LRLT (15 times operation, including 2 cases of liver retransplantation) in our department from January 2001 to December 2002. ResultsAll the operations were successful. All the 13 donors were followed up regularly, 12 donors were uneventfully recovered after operation and 1 donor suffered from bile leakage due to T tube. The survival rate of recipients, who achieved longterm survival at 2 months to 2 years, was 92.3%(12/13); the survival rate of graft was 86.7%(13/15). One adult recipient with Wilson’s disease died of serious rejection on the 72nd day postoperatively. Two cases suffered from embolism of hepatic artery, one case received reduced size cadaveric liver retransplantation, the other case received liver retransplantation from cadaver, and they both achieved longterm survival after retransplantation. The other complications included: 1 case of serious rejection, 2 cases of ARDS, 6 cases of infection of microbe, 7 cases of serious hydrothorax, 1 cases of leakage of biliary tract, and so on. ConclusionPerfect preoperative management, which composes one of the key parts of LRLT, is critically important for both donor and recipient.

ResultsLRLT made much progress on evaluation of donor, harvesting the graft liver, donor health assessment and outcomes after living donor liver transplantation, and main factors affecting the survival of liver graft and so on. Conclusion Living related liver transplantation has many unsurpassable advantages, which suits the situation of China and has capacious clinical application.
Objective To summarize the experience of the prevention of early arterial compl ications after hepatic artery (HA) reconstruction in adult-to-adult l iving donor l iver transplantation (A-A LDLT). Methods Between January 2002and March 2008, 127 patients underwent A-A LDLT. Of the 131 donors (127 cases of right lobe graft, 4 cases of left lobe graft), there were 69 males and 62 females with a mean age of 36.2 years (range, 19-65 years); in 127 recipients, there were 109 males and 18 females with a mean age of 41.9 years (range, 18-64 years). All patients underwent microsurgical reconstruction of HA between grafts and recipients. The artery of graft was anastomosed to the right HA in 62 cases, to the proper HA in 34 cases, to the left HA in 7 cases, to the common HA in 6 cases, and aberrant right HA rising from superior mesenteric artery in 8 cases. Interposition bypass using great saphenous vein (GSV) was performed between the donor right HA and recipient common HA in 5 cases. Bypass was performed between the donor right HA and recipient abdominal aorta using GSV in 2 cases, or using cryopreserved cadaveric il iac vessels in 3 cases. Results Of these 127 cases, hepatic artery thrombosis (HAT) occurred in 2 recipients (1.6%) at 1 day and 7 days following A-A LDLT, which were successfully revascularized with GSV between right HA of donor and abdominal aorta of recipient, HAT in 1 patient occurred on the 46th postoperative day with no symptom. No other arterial compl ication such as HA stenosis and aneurysm occurred in recipients. All patients were followed up 9-67 months. At 1, 2, and 3 years, actual survival rateswere 82.2%, 64.7%, and 59.2%. No death was related to HA compl ication in peri-operative period. Conclusion The anatomic structure and variation of HA, the pathological changes, as well as surgical technique in HA reconstruction, have direct impact on the risk of postoperative compl ications of HA reconstruction.
Objective To investigate the effectiveness of free vascularized fibula grafting with unilateral fibula as donor in treatment of bilateral avascular necrosis of femoral head (ANFH). Methods Between June 2007 and January 2008, 14 patients with bilateral ANFH were treated with free vascularized fibula grafting with unilateral fibula as donor. There were 12males and 2 females with an average age of 36.6 years (range, 17-57 years). The necrosis was caused by use of steroids in 3 cases, consumption of alcohol in 4 cases, and idiopathic condition in 7 cases. According to Steinberg system, 16 hips were classified as stage II, 10 hips as stage III, and 2 hips as stage IV. The preoperative Harris hip scores were 77.50 ± 4.19, 69.70 ± 2.76, 59.50 ± 0.50 in patients at stages II, III, and IV, respectively. The duration of operation and the bleeding volume were recorded. The X-ray examination, the Harris hip score, and the compl ications were used to evaluate the effectiveness. Results The duration of the fibula osteotomy was 10-32 minutes (mean, 20 minutes). The duration of the total operation was 100-240 minutes (mean, 140 minutes). The bleeding volume was 200-500 mL (mean, 280 mL). All patients achieved heal ing of incision by first intention. The patients were followed up 12-40 months (mean, 24 months). One case had numbness and hyperthesia of the anterolateral thigh; 1 case had abnormal sensation of the dorsal foot; 1 case had discomfort of the ankle; and they restored to normal at 1 year after operation. According to X-ray films 1 year after operation, the improvement was achieved in 23 hi ps (82.1%) and no deterioration in 5 hips (17.9%). At 1 year after operation, the Harris hip scores were 93.90 ± 4.84, 88.50 ± 8.13, and 78.00 ± 0.00 inpatients at stages II, III, and IV, respectively, showing significant differences when compared with preoperative ones (P lt; 0.05). Conclusion Unilateral free vascularized fibula grafting has lots of virtues, such as short surgical time, less bleeding volume, l ittle injury, and good results of function recovery. It could be an effective and safe method in treating bilateral ANFH.
Objective To review the vascular anatomy of the donor and the reci pient for the l iving kidney transplantation. Methods The recent l iterature about the vessels of donor and reci pient in cl inical appl ications was extensively reviewed. Results The pertinent vascular anatomy of the donor and recipient was essential for the screening of the proper candidates, surgical planning and long-term outcome. Early branching and accessory renal artery of the donor were particularly important to deciding the side of nephrectomy, surgical technique and anastomosing pattern, and their injuries were the most frequent factor of the conversion from laparoscopic to open surgery. With increase of laparoscopic nephrectomy indonors, accurate venous anatomy was paid more and more attention to because venous bleeding could also lead to conversion to open nephrectomy. Multidetector CT (MDCT) could supplant the conventional excretory urography and renal catheter angiography and could accurately depict the donors’ vessels, vascular variations. In addition, MDCT can excellently evaluate the status of donor kidney, collecting system and other pertinent anatomy details. Conclusion Accurate master of related vascular anatomy can facil iate operation plan and success of operation and can contribute to the rapid development of living donor kidney transplantation. MDCT has become the choice of preoperative one-stop image assessment for living renal donors.
To discuss renovascular reconstruction during l iving related donor kidney transplantation (LDKT). Methods Seventy-seven cases of LDKT from April 2006 to March 2008 were retrospectively analyzed, including 63 cases in single renal artery group and 14 cases in multi ple artery group. In multi ple artery group, there were 3 cases of three arteries and 11 cases of double arteries; 9 cases of donated left kidneys and 5 cases of donated right kidneys. Potential donors underwent fully medical evaluation before operation, including donor-reci pient human leucocyte antigen matchingand a cross match test. The donor’s operation of the incision either underneath the 12th rib approaching the dorsal lumbar was performed and the transplantation operation adopted the extraperitoneal approach in the contralateral fossa il iac. The arteries in the multiple artery group were implanted onto the external (or common) il iac artery different from the orthodox method. Results In multiple artery group, no blood transfusion during operation was performed, no compl ication occurred after operation and all donors were discharged after 7-9 days of postoperation. After a follow-up of 3 months to 1 year, all the recipients kept normal kidney function without renal tubule necrosis, renal artery embol ism, vascular stenosis, urinary fistula and ureter necrosis. The ultrasound examination showed that the transplanted kidney had good blood supply. There was no significant difference in the time of urine secretion, serum creatinine level after 1 week of operation, length of hospital ization between the multiple artery group and the single artery group (P gt; 0.05). Conclusion The accurate treatment of multiple artery anastomosis are critical for the safety of the LDKT.
