Objective To compare and evaluate the short-term outcomes of 3 different tricuspid valve plasty for functional tricuspid regurgitation (TR) in patients with rheumatic heart disease. Methods Between October 2010 and June 2011, 148 patients with rheumatic heart disease undergoing left heart valve replacement and tricuspid valve plasty for functional TR were enrolled in the study. There were 32 males and 116 females with an average age of 47.5 years (range, 15-66 years). The patients were divided into 3 groups depending on tricuspid valve plasty: Cosgrove-Edwards annuloplasty ring group (annuloplasty ring group, 58 cases), Kay annuloplasty group (Kay group, 61 cases), and DeVega annuloplasty group (DeVaga group, 29 cases). There was no significant difference in general data among groups (P gt; 0.05), except more severe TR degree, higher atrial fibrillation, and higher radiofrequency ablation in annuloplasty ring group (P lt; 0.05). Perioperative data were recorded. The heart function was evaluated according to the standard of New York Heart Association (NYHA). Echocardiography (ECG) was used to record the TR class during perioperative period and follow-up. Results After operation, 1 case in Kay group and 1 case in annuloplasty ring group were dead because of low cardiac output syndrome. Pneumonia happened in 2 cases of Kay group and in 1 case of annuloplasty ring group; re-operation was performed in 1 case of annuloplasty ring group because of sternal dehiscence. There was no significant difference in perioperative complication among 3 groups (P=0.840). The TR degree was significantly improved at discharge when compared with preoperative degree in 3 groups (P lt; 0.001). A total of 146 patients were followed up 6-12 months (mean, 7.3 months). The NYHA grade of 3 groups at last follow-up was improved when compared with preoperative grade (P lt; 0.001), but no significant difference among 3 groups (χ2=0.120, P=0.942). The TR degree at last follow-up was all improved in 3 groups when compared with preoperative degree (P lt; 0.001); the improved efficiency showed significant difference among 3 groups (χ2=26.827, P=0.000), it was significantly better in annuloplasty ring group than in the other 2 groups (P lt; 0.001), but no significant difference between DeVega group and Kay group (Z=1.467, P=0.142). Conclusion The early improved efficiency of TR after Cosgrove-Edwards annuloplasty is superior to that of Kay annuloplasty and DeVega annuloplasty.
Objective To study the effect of core decompression combining with autologous cortical sustaining bone and cancellous bone graft in treating osteonecrosis of the femoral head (ONFH). Methods From February 2004 to May 2008, 64 patients (77 hi ps) with ONFH were treated with core decompression combining with autologous cortical sustaining bone and cancellous bone graft, including 45 males and 19 females and aging 23 to 60 years with an average age of 43 years. There were 51 cases of unilateral ONFH and 13 cases of bilateral ONFH. ONFH was caused by alcohol in 39 cases(47 hi ps), by steroid in 21 cases (26 hi ps), and by trauma in 4 cases (4 hi ps). The disease course was 1-12 years. The pain time was 2-14 months (average 7 months). All the cases underwent imageology and postoperation pathology examination to confirm the diagnosis of ONFH. According to Association Research Circulation Osseous (ARCO) international classification of osteonecrosis, 17 cases (23 hips) were classified as stage I A, 2 cases (3 hips) as stage I B, 21 cases (24 hips) as stage II A, 2 cases (2 hips) as stage II B, 4 cases (4 hips) as stage II C, and 18 cases (21 hips) as stage III A. The outcome was evaluated both cl inically by Harris score and radiologically by imageology. Results A total of 59 cases (69 hips) were followed up for 12-62 months with an average of 32.1 months. The Harris score was 87.12 ± 8.68 at 12 months after operation, showing significant difference (P lt; 0.05) when compared with the preoperative one (68.38 ± 14.49). The results were excellent in 39 hips, good in 18 hips, fair in 6 hips, and poor in 6 hip; and the excellent and good rate was 82.6%. Radiographic evaluation was 21 hips (30.4%) of grade I, 42 hips (60.9%) of grade II, and 6 hips (8.7%) of grade III. One case had the compl ication of il ium bone donor site, 21 cases had l ittle pain or numbness, and the other cases had no uncomfortable compl ication. Conclusion The method of core decompression combining with autologous cortical sustaining bone and cancellous bone graft can improve the means of bone grafts, prevent the collapse of the femoral head, and is less traumatic than common procedures. Cl inical effects are obvious and effective.
Objective To investigate the effect of a new suturing method called two-layer closure and to compare this with the traditional four-layer suturing method. Methods A randomized controlled trial was conducted in patients admitted from January to April 2008. A total of 124 eligible patients were divided into 2 groups. Sixty-one patients in the trial group received two-layer closure, while 63 in the control group received four-layer closure. The baseline conditions before the operation, incision parameters, and the recovery of the body and incision after the operation were compared between the 2 treatment groups. Results The baseline characteristics of the groups were similar. No significant differences were observed in terms of the length of hospital stay, time to food intake, time to ground activity, and time to first passage of gas by anus (Pgt;0.05). However, the incidence of fever after the operation was significantly lower in the trial group compared with the control group (P=0.014). The healing level of the incisions was comparable between the 2 groups (Pgt;0.05). As for complications after the operation, no cases of incision infection or incision granuloma or sinus tract were reported. However, 3 cases of active hemorrhage and 2 cases of incision split occurred in the control group. Moreover, the incidence of incision liquefaction in the trial group was significantly lower than that in the control group (P=0.03). Conclusion For abdominal median incision, two-layer closure is associated with smaller incision trauma, less stimulation from extraneous materials, as well as more accurate anatomic replacement compared with the traditional four-layer closure. However, further studies need to be conducted to determine whether the new suturing method of twolayer closure is effective and safe for other kinds of incision.
Objective To explore the effectiveness of Colorado 2TM system in the stabil ity reconstruction of sacroil iac joint fracture and dislocation in Tile C pelvic fracture. Methods Between February 2009 and January 2011，8 cases of Tile C pelvic fracture were treated with Colorado 2TM system. There were 3 males and 5 females with an average age of 34.4years (range，22-52 years). Fractures were caused by traffic accident in 3 cases, by fall ing from height in 3 cases，and by crash of heavy object in 2 cases. According to Tile classification, 5 cases were classified as C1-2, 2 cases as C1-3，and 1 case as C2. The time between injury and operation was 5-10 days (mean, 7 days). After skeletal traction reduction, Colorado 2TM system was used to fix sacroil iac joint, and reconstruction plate or external fixation was selectively adopted. Results The postoperative X-ray films showed that the reduction of vertical and rotatory dislocation was satisfactory, posterior pelvic ring achieved effective stabil ity. All the incisions healed by first intention, and no blood vessel or nerve injury occurred. Eight patients were followed up 6-24 months (mean, 12 months). No loosening or breakage of internal fixation was observed and no re-dislocation of sacroil iac joint occurred. The bone heal ing time was 6-12 months (mean, 9 months). According to Majeed’s functional criterion, the results were excellent in 5 cases, good in 2 cases, and fair in 1 case at last follow-up. Conclusion Colorado 2TM system could provide immediate stabil ity of pelvic posterior ring and good maintenance of reduction effect, which is an effective method in the therapy of sacroil iac joint fracture and dislocation in Tile C pelvic fracture.
