Clinical Medicine of China 2010;26(7):707-709
Objective To compare the efficiency of repairing perimembranous ventricular septal defect (VSD) with continuous stitching to that with interrupted stitching. Methods Of the 158 patients with perimembranous VSD ( 54% males) ,102 ( 65% ) patients underwent the repairing of continuous stitching (continuous group) ,and 56 patients underwent interrupted stitching (interrupted group). All the surgeries were performed under hypothermic cardiopulmonary bypass. Results The cardiopulmonary bypass time and aortic cross-clamp times were (31 ±14) mins and (18 ±12) mins in the continuous group, which was significantly less that those of (42 ± 16) mins and (25 ±11) mins in the interrupted group (t =4.49 and 3. 61 .respectively ,P <0. 05) . No case was died. The main complications involved temporary M atrioventricular block (AVB) of two cases (1 case in each group),which disappeared after 1 week. There were two remnants remaining leak (n =2) which was less than 3 mm and automatically cured after 3-6 months. Complete right bundle branch block(CRBBB) occurred in 3 cases in the continuous group and 6 cases in the interrupted group,of which 3 disappeared after 1 month and 2 disappeared after 12 months. The outcome was good in all cases after 1-3 years follow up. Conclusions Continuous stitching showed a shorter cardiopulmonary bypass and aortic cross-clamp times, and reduced the CRBBB.

[Objective] To compare the efficacy of interbody fusion with cage versus corpectomy and fusion with plate in treating adjacent two-level cervical spondylosis.[Method] Sixty patients were included in this study.All patients were randomly assigned to anterior interbody fusion with cage (AIFC) group or anterior corpectomy and fusion with plate (ACFP) group. The average follow-up period was 28 months for AIFC group,and 25 months for ACFP group. [Result] The average loss of lordosis angle, the lost correction of segmental height and the scores on the criteria of 40-score method were not statistically significant between these 2 groups. The lordosis correction, operative estimated blood loss, and operative time were statistically better in the AIFC group significantly . [Conclusion] The short-term results of AIFC and ACFP in treating adjacent two-level cervical spondylosis were satisfactory. The advantages of AIFC are the elimination of donor site complications, increasing more segmental lordosis, and reducing blood loss and operative time.
