AIM: To introduce a novel technique for transscleral fixation of the PC-IOL that requires no sutures on the IOL haptics. METHODS: Instead of suturing polypropylene onto the IOL haptics, the method simply winds the thread on the haptics. Fifteen eyes of 15 patients underwent this technique and were followed up for more than 18 months. Surgical outcomes and post-operative complications were evaluated and compared with those of the conventional transscleral fixation method. RESULTS: Postoperative cylinder was significantly lower in the thread winding group than in the conventional transscleral fixation method group (-1.02±0.46 diopters vs -1.57±0.77 diopters; P=0.01). Further, no postoperative complications, such as optic capture, IOL dislocation, and hyphema, were detected in the thread winding group. CONCLUSION: We believe that our thread winding technique is better than previously reported methods because it is simple, mechanically stable, and free from suture-related complications. 相似文献

影像学评估在耳蜗植入术中的价值 总被引:2,自引:0,他引:2
目的:评价影像学检查在耳蜗植入术中的价值。方法:37例感音性神经性聋患者术前常规行颞骨HRCT及MRI检查,术后行改良斯氏位X线拍片,其中5例术后行CT复查。结果:CT显示2例Mondini畸形(4耳),2例前庭导水管扩张(4耳),1例迷路骨化(1耳),1例内听道狭窄(2耳)。MRI显示Mondini畸形3例(6耳),前庭导水管扩张2例(4耳),1例并内淋巴囊扩张(2耳),2例迷路纤维化(2耳)。术后改良斯氏位X线拍片显示植入电极形态、位置良好。CT显示1例电极滑脱。结论:CT及MRI对耳蜗植入术术前评估具有重要价值,改良斯氏位X线拍片结合CT对术后评估更有意义。 相似文献

Objective The degree of Left Ventricular Mass Index (LVMI) regression following aortic valve replacement correlates with long-term survival.
This study aims to assess the extent of LVMI regression at 3 months following aortic valve replacement (AVR) with different
types and sizes of mechanical valves in rheumatic aortic valve disease.
Methods The LVMI regression was studied in 34 consecutive patients, undergoing elective AVR for rheumatic aortic stenosis and/or regurgitation.
They were grouped in A and B, matched in age, body surface area and pre-operative LVMI, receiving respectively a tilting disc
and a bileaflet mechanical valve. The LVMI was calculated by M-mode echocardiography using the Devereux' formula pre-operatively
and three months post-operatively. The trend of LVMI reduction was compared between the two groups and amongst the patients
with stenotic, regurgitant and mixed aortic valve, pathologies; and receiving different sizes of valves.
Results The mean preoperative LVMI was 199g±79.5 g/m2. At three months post aortic valve replacement, the mean LVMI was 130g±49.0 g/m2. There was a significant reduction of LVMI post-operatively (p=0.001) at three months follow-up. The extent of LVMI regression
following surgery amongst the groups A and B did not vary significantly (p=0.92). The extent of LVMI regression did not vary
significantly in patients with different aortic valve pathology nor with different sizes of the valves implanted.
Conclusions There is a significant early LVMI regression following aortic valve replacement in rheumatic aortic valve disease. The type
and the size of the mechanical prosthesis or the rheumatic pathology do not appear to influence this regression. 相似文献

We report the case of a 4-year-old girl who had quadricuspid aortic valve regurgitation with tetralogy of Fallot and pulmonary
atresia. This combination is very uncommon. Aortic valve replacement was performed successfully due to aortic regurgitation
which had progressed one year after the total repair. The dilated aortic annulus plus quadricuspid aortic valve may result
in progressive aortic regurgitation for a short period. 相似文献

Background Despite improving surgical techniques, treatment of heart valve disease in children remains controversial. Somatic growth
and adequate anticoagulation are of concern when children undergo valve replacement. We conducted this study to evaluate the
performance of valves in this age group.
Methods 42 children under the age of 13 years who underwent valve replacement were included in this study. Totally, 50 valves were
implanted in 42 patients: 48 were mechanical prostheses, two were bioprosthetic both in pulmonary position. 37 (74%) valves
were implanted in mitral position, 10 (20%) in aortic position, 1 (2%) in tricuspid position and 2 (4%) in pulmonary position.
Preoperatively, 14 (33,3%) patients were in New York Heart Association (NYHA) class IV, while 27 (64.2%) were in NYHA class
III.
Results There were 2 (4.7%) hospital deaths and 2 (4.7%) late deaths while 2 (4.7%) patients were lost to follow up. The mean follow
up period was 9.4 yrs. 35 (83.3%) patients are in NYHA Class I and free of all medications except warfarin. 3 (7.1%) patients
have undergone 5 successful pregnancies. The median INR was 2.23. Major thrombo-embolic episode occurred in 1 (2.3%) patient.
Conclusions In view of the problems of sizing, anticoagulation and need for re-operation at an early age, there is a reluctance to replace
valves in children. This study shows that despite these problems, valve replacement can be undertaken safely and successfully
in children, when repair has failed or not technically feasible. 相似文献
