Methods: Between 1999 and 2001, 43 adult patients underwent OLT with v-v bypass, 33 with no v-v bypass. The operation time, anhepatic time, amount of blood loss, amount of blood transfusion, ICU stay days of the two groups were compared; renal function and gastrointestinal function in the two groups were examined. Results: There was no significant difference in mean serum creatinine on day 3 and gas discharge time in patients with v-v bypass or not. With no v-v bypass , the average operation time was 5.7±1.3 hours, anhepatic time was 64±13 minutes, median amount of blood loss in operation was 4000±820 mL, median amount of blood transfused intraoperatively was 4650±910 mL, median ICU stay was 5.7 days; all those were lower or shorter than those with v-v bypass; and these differences between the two groups had statistical significances. Conclusion: OLT with no v-v bypass is safe and can be performed in the majority of adult patients. The practice of liver transplantation with no v-v bypass is associated with shorter total operation time, shorter anhepatic time, lower blood product usage, and shorter ICU stay compared with standard technique of OLT with routine use of v-v bypass.展开更多

Methods The data of 312 patients (average age 65±9 years) who had CABG operation in Hartford hospital were collected and analyzed. The mean duration follow up after the first CABG was 11.8±4.5 years. A total of 1069 bypass grafts were performed. Among them, 386 were arterial grafts such as internal mammary artery, radial artery and gastroepiploic artery; 682 were venous grafts and 1 Gore-Tex graft. Results The operative mortality was 4.5%. Fifteen patients ( 4.8%) had peri-operative myocardial infarction and 46 patients (15%) had low cardiac output syndrome. Intra-aortic balloon pump (IABP) was used in 131 patients before, during and after operation. One hundred and nineteen patients weaned off IABP and recovered. Conclusion Although the difficulties and risk factors were increased, the results of redo CABG were still good.展开更多

Methods: Thirty cases of fresh transcervical and subcapital fractures of the femoral neck were treated by the tail breakable screws and sartorius pedicle bone grafts (single muscular pedicle, SMP group). The other 23 cases were treated by cannulated pressure screws and bone grafts with the muscular pedicles of both sartorius and tensor fasciae latae (double muscular pedicles, DMP group). Results: Fifty-two cases were followed up for 3 to 5 years (mean, 4 years). In SMP group, ten cases showed poor therapeutic results. Excellent therapeutic effects were achieved in all cases of DMP group. Conclusions: The transcervical or subcapital fractures of the femoral neck can be treated by double muscular pedicles bone graft. The bone graft with double muscular pedicles is more effective than single sartorius muscular pedicles for fresh transcervical and subcapital fractures of the femoral neck during short and medium terms.展开更多
