Abstract Dual-blade plate is widely used in reconstruction of anterior stability of spine. Two hundred and ninety-eight cases were followed up since 1984. Among them, 181 cases were fractureof thoracolumbar spine; 63 cases were tuberculosis of thoracolumbar spine; 43 cases were tumor of thoracolumbar spine; 5 cases were spondylisthesis of lumbar spine; 2 cases were ankylosing spondylitis accompanied with gibbosity; 2 cases were adolescent vertebral epiphysis; I case was hemivertebra; I case was dysplasia of the first lumbar vertebra acompanied with gibbosity. Most cases were successful following operation, but in some cases, the results were unsuccessful, mainly due to the position of the dualblade plate in the vertebral body was not satisfactory. The mistakes most commonly occurred were one or two blades, or a part of the blade going into the intervertebral space, and less commonly seen was deviation of the dual -blade plate from itscorrect orientation or a little side-bent of the blade. Split of the vertebra and fall off of the dual-blade plate were happened in few cases. The causeswere analyzed and ways of prevention were provided in this article.
Objective To summarize research progress of postoperative complications of transilluminated powered phlebectomy in treatment of varicose veins. Method The clinical and scientific research about the treatment of varicose veins with transilluminated powered phlebectomy in recent years were searched and the progress of the postoperative complications were reviewed. Results With the evolution of surgical techniques and the accumulation of experience, a variety of translucent resection of the postoperative complications such as the cellulitis, wound abscess, hematoma, residual vein, nerve damage reduced. Conclusions From current development trend, incidence of complications after transilluminated powered phlebectomy might continue to decline. It has a potential to become a mainstream surgical technique for varicose veins in future.
Objective To investigate the complications of the Branch Retinal Vein Occlusion. Methods Two hundred and seventy-seven cases (277eyes) of branch retinal vein occlusion (BRVO) have been studied retrospectively from 1995 October to 1999 October Results Most cases of BRVO occured after the age over fifty-five. About 81.85% BRVO affected at supiriotemporally and inferiotemporally. The incidence of the complication of BRVO is closely related to the site of obstrution, the larger branch vein occlusion the higher incidence of the nonperfusion area and neovascularization Conclusion The macular edema occured in the early stage of the BRVO, and most non-perfusion areas were observed between six to twelve months. The neocvscularization always observed after one year later from the vein obstruction. So that the patient have to be followed carefully with a long duration. （Chin J Ocul Fundus Dis,2002,18:17-19）
ObjectiveTo study the clinical characteristics of elderly hemodialysis (HD) patients and discuss how to control their complications, in order to improve their quality of life and lower their mortality rate. MethodContrastive study and analysis were performed on the clinical data of 98 maintenance HD patients (between elderly and young HD patients) between January 2013 and January 2014. Complications, rate of hospitalization and mortality were analyzed during the follow-up of one year. ResultsThe ratio of hypertensive kidney disease and diabetic nephropathy, as primary disease of the elderly HD patients, gradually increased. More people chose to use semi-permanent jugular vein catheter for elderly HD patients. Compared with young HD patients, the levels of hemoglobin, albumin, serum creatinine, KT/v were lower in the elderly patients, and C-reactive protein was much higher (P<0.05). There was no significant difference in cholesterol, triglyceride, calcium, phosphorus, parathormone between the two groups (P>0.05). Dialysis-related hypotension and blocking of vascular access occurred more frequently in elderly HD patients. Hospitalization rate and mortality rate were higher in elderly HD patients (P<0.05). ConclusionsImproving nutritional status, keeping vascular access unobstructed for a long time and decreasing complications related to hemodialysis are helpful for elderly HD patients to enhance their quality of life and reduce the mortality rate.
ObjectiveTo evaluate the clinical value of multi-slice CT in the diagnosis of complications due to breast augmentation. MethodsWe collected the imaging data of 32 female patients who accepted multi-slice CT examination in the second People's Hospital of Chengdu after breast augmentation between February 2010 and February 2015. The position, shape, edge, internal density, leakage, rupture and hard nodules of the prosthesis were observed and analyzed carefully. ResultsIn the 32 patients with breast augmentation, 12 were normal with bilateral symmetry and without abnormal shape or density. Among the other 20 patients, 11 had capsular contracture, 5 had prosthesis leakage, rupture and hard nodules, 4 had breast infection, 1 had fibroadenoma, 1 had cystoma, and 5 had little calcified nodules in the breast tissue. ConclusionThe multi-slice CT scan can clearly and accurately show the position, shape and size of the breast prosthesis as well as the existence of leakage, rupture and hard nodules in the prosthesis. It plays a very important role in the diagnosis of the complications due to breast augmentation and can be effective guidance for clinical operation.
目的 探讨结肠癌和直肠癌并发肠穿孔的外科诊治方法。方法 分析13例结直肠癌并发肠穿孔患者的临床资料。结果 13例患者中4例行肿瘤所在肠段一期切除吻合术； 4例行一期病灶切除吻合术，近端肠段行外置双管造瘘术； 2例切除肿瘤所在肠段，近端行端式结肠造瘘术，远端行封闭（Hartmann）术； 3例行单纯肠造瘘术。术后并发症发生率为46.15%（6/13），手术死亡率为15.38%（2/13）。结论 重视对结直肠癌并发肠穿孔的认识及选择合适的手术方式是减少并发症、提高疗效的重要措施。
Peripapillary intrachoroidal cavitation (PICC) is a common pathological change observed in high myopia. The exact pathogenesis of PICC is still unclear. Expansion and mechanical stretching of the peripapillary sclera, breakage and defect in the retina near the border of the myopic conus and communication between intrachoroidal cavity and the vitreous space may be important segments during the development of PICC. Color fundus photography shows a localized and well-circumscribed peripapillary lesion with yellow-orange colour, often accompanied by fundus changes, such as myopic conus excavation, optic disc tilting and inferotemporal retinal vein bending at the transition from the PICC to the myopic conus. However, the PICC lesion is not easy to be recognized in the fundus photography. Fluorescein angiography shows early hypofluorescence and later progressively staining in the lesion. Indocyanine green angiography shows hypofluorescence throughout the examination. Optical coherence tomography (OCT) is vital in diagnosing PICC. Hyporeflective cavities inside the choroid, sometimes communicating with the vitreous chamber, can be observed in OCT images. OCT angiography indicates lower vessel density or even absence of choriocapillary network inside or around PICC lesions.
