Objective To evaluate the cl inical results of allogeneic bone graft for interbody fusion in cervical tuberculosis. Methods Between January 2000 and January 2008, 30 cases of cervical tuberculosis were treated with allogeneic (group A, n=15) or autologous (group B, n=15) il iac crest bone graft combined with anterior fixation after radical debridement. In group A, there were 8 males and 7 females with an average age of 38 years; the disease duration was 6 to 14 months; the preoperative kyphosis Cobb angle was (8.6 ± 11.3)°; the preoperative Japanese Orthopaedic Association (JOA) score was 13.0 ± 3.1 for neurological function; and the length of bone graft was 32 mm on average. In group B, there were 9males and 6 females with an average age of 42 years; the disease duration was 4 to 17 months; the preoperative kyphosis Cobb angle was (4.9 ± 7.4)°; the preoperative JOA score 12.3 ± 4.2; and the length of bone graft was 34 mm on average. There was no significant difference in general data between 2 groups (P gt; 0.05). Results The operation time and bleeding volume in group A were significantly less than those in group B (P lt; 0.05). Wound effusion were found in 2 cases of group A, and the other incisions healed by first intention. No infection occurred in group B. In group A, 13 cases were followed up 12-48 months; in group B, 14 cases were followed up 13-46 months. The time of bone graft heal ing in group A [(7.6 ± 2.1) months] was significantly longer than that in group B [(4.2 ± 1.1) months] (t=2.773, P=0.005). The kyphosis Cobb angles were significantly improved at 6 months and last follow-up after operation in 2 groups when compared with that before operation (P lt; 0.05), but no significant difference was found between 2 groups at different time after operation (P gt; 0.05). There was no significant difference in JOA score at 6 months after operation between group A (14.1 ± 2.6) and group B (14.3 ± 2.4) (t=1.655, P=0.162). The improvement rate for neural function were 83.7% in group A and 87.8% in group B, showing no significant difference (χ2=3.150, P=0.071). There was no loosening of internal fixation and recurrence of tuberculosis in 2 groups during follow-up. Five cases had chronic pain at il iac donor sites in group B. According to Bridwell et al. evaluation standard, the bone fusion was satisfactory in 11 cases (84.6%) and unsatisfactory in 2 cases (15.4%) in group A, and was satisfactory for all in 14 cases (100%) in group B. The satisfactory rate of bone fusion showed no significant difference between 2 groups (χ2=2.680, P=0.115).Conclusion Allogeneic bone grafting has a good cl inical result for spinal fusion in cervical tuberculosis surgery, which can treat tuberculosis bone defect effectively.
目的 总结超选择性肾动脉栓塞治疗经皮肾镜取石术后严重出血的临床经验。 方法 回顾分析2009年10月-2012年11月行经皮肾镜取石术后发生严重出血的6例(2.74%)患者的临床资料和对其进行超选择性肾动脉栓塞术的血管造影表现和栓塞疗效。 结果 患者平均年龄67岁,经皮肾镜取石术后急性出血1例,迟发出血5例,均有体外冲击波碎石史或糖尿病、高血压病史。肾动脉造影显示损伤动脉为肾后下段动脉、肾下段动脉分支,表现为假性动脉瘤5例,动静脉瘘1例。使用弹簧圈或聚乙烯醇颗粒超选择性栓塞,栓塞后出血无一例复发。随访6个月,5例肾功能未见下降,1例受损。 结论 经皮肾镜术后严重出血与术中动脉损伤有关,采用超选择性肾动脉栓塞术能够达到迅速止血、尽可能保全患肾功能、有效挽救生命的诊疗效果。
ObjectiveTo study a new method for establishing the rat model of incomplete adhesive intestinal obstruction. MethodsThe serosal stripping method was adopted, the general health condition changes of rats were observed on day 3, 5, and 7 after modeling, meanwhile the weight was measured, the superior mesenteric artery flow velocity and small intestine wall thickness were observed via the color Doppler ultrasound and orthostatic X ray. The level of D-lactate acid in the blood plasma, and the activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in the intestine tissue were tested. The pathological changes of the intestine tissue were observed. ResultsCompared with the normal group (no treatment was done), the general health conditions of rats were worse, the weight significantly decreased (Plt;0.01), the superior mesenteric artery blood flow velocity significantly increased and small intestinal wall was thickened (Plt;0.05, Plt;0.01), airfluid level or a great deal of seroperitoneum and pneumatosis flat appeared via orthostatic abdominal X-ray, the level of D-lactic acid in the blood plasma and the content of MDA in the intestine tissue significantly increased on day 5 after modeling (Plt;0.05, Plt;0.01), the activity of SOD in the intestine tissue significantly decreased on day 7 after modeling in the model group (Plt;0.05). The pathological changes consistented with adhesive intestinal obstruction via pathological observation. On the 7th day, the rat model of incomplete adhesive intestinal obstruction was successfully built . ConclusionThe rat model of incomplete adhesive intestinal obstruction is completed by serosal stripping method.
