  • Comparison of Perioperative Results in Different Operative Approaches in Repairing Tetralogy of Fallot

    Objective To compare perioperative results between transventricular and transatrialtransventricular approaches in repairing tetralogy of Fallot (TOF), and to improve the surgical results. Methods The data of 1 423 consecutive patients who underwent complete repair of TOF between January 1998 and December 2007 were reviewed. 736 patients were repaired by the transventricular approach,and 687 patients by the transatrialtransventricular approach. Results Patients repaired by transventricular approach decreased from 100% in 1998 to 65% in 2002, and by transatrialtransventricular approach increased from 35% in 2002 to 79% in 2007. Aortic clamping time, cardiopulmonary bypass (CPB) time,mechanical ventilation time,and intensive care unit (ICU) stay in patients repaired by transatrialtransventricular approach had less than those in patients repaired by transventricular approach. No difference in transvalve patch ratio.There was lower morbidity in patients repaired by transatrialtransventricular approach in one to two organ systems dysfunction than that in patients repaired by transventricular approach. No difference in three or more organ systems dysfunction between them. Rate of residual ventricular septal defect(VSD), right ventricule to mean pulmonary artery (MPA) pressure gradient, tricuspid regurgitation, pulmonary artery regurgitation and arrhythmia in patients repaired by transatrialtransventricular approach were less than those in patients repaired by transventricular approach. Reoperative rate and mortality in patients repaired by transatrialtransventricular approach were less than those in patients repaired by transventricular approach. Conclusion TOF repair by the transatrialtransventricular approach fits to the actual conditions in China.

  • Therapeutic effect of laser photocoagulation on diabetic retinopathy at different stages

    bjective To observe the therapeutic effect of laser photocoagulation on diabetic retinopathy (DR)at different stages.Methods A total of 534 eyes of 304 patients with DR diagnosed by fundus fluorescein angiography (FFA) were enrolled in this study. In the 534 eyes, 92 with nonproliferative DR (NPDR) had the bestcorrected visual acuity(BCVA) of 0.52plusmn;0.32,108 with preproliferative DR (PPDR) had the BCVA of 0.49plusmn;0.23,196 with early PDR had the BCVA of 0.20plusmn;0.31,and 138 with highrisk PDR had the BCVA of 0.17plusmn;0.22. According to the rules of ETDRS, retinal photocoagu1ation,pan retinal photocoagu1ation or extrapanretinal photocoagu1ation were performed on the paitents with NPDR,PPDR,and highrisk PDR,respectivelyThe patients were followed up for 10-18 months after the operations and the results of the examinations at the last time were regarded as the criteria for judgement. The examination of BCVA and ocular fundus and FFA were performed with the time interval of 3 months.The judgement for BCVA was(1)improved:improved ge;2 lines;(2) kept still: changed within 2 lines;(3)decreased:decreased ge;2 lines.And the effect on BCVA was positve when it was improved or kept still.The judgement for the therapeutic effect on DR was:retinal edeama was alleviated,leakage of hemorrhage was obsorbed,microaneurysm disappeared or decreased, neovascularization (NV) was relieved completely or partly,nonperfusion area disappeared or narrowed, and no new NV or nonperfusion area came into being. Results After the operations, BCVA in NPDR,PPDR and early PDR groups was improved or kept still in 73(79.3%),83(76.9%),and 146 eyes (74.5%), respectively,without any statistical difference among these three groups(P>0.05).BCVA in highrisk PDR group was significant lower than that in the NPDR,PPDR,and early PDR groups (P<0.05). The positive rate of therapeutic effect on DR was 89.1%,85.2%,82.7% in NPDR,PPDR,and early PDR groups, respectively without any statistical difference among the groups(P>0.05). The positive rate of therapeutic effect on DR in highrisk PDR group was significant lower than that in the NPDR,PPDR,and early PDR groups(P<0.05). Conclusion The prognosis of DR at different stages after laser photocoagulation is different;timely and effective laser photocoagulation is important to prevent the development of the disease and decrease the blindness rate.
