Objective To investigate the effect and prognosis of patients with ventricular septal rupture after myocardial infarction treated by surgical repair combining an occluder and a patch. Methods Clinical data of 42 patients with myocardial infarction complicated with ventricular septal rupture admitted to the First Affiliated Hospital of Zhengzhou University from January 2010 to September 2021 were retrospectively analyzed. According to the surgical methods, 27 patients were divided into a traditional group, including 17 males and 10 females, with an average age of 62.81±6.81 years, who were repaired by patch only, and 15 patients were divided into a modified group, including 11 males and 4 females, with an average age of 64.27±9.24 years, who were repaired by surgery combining an occluder and a patch. Perioperative and follow-up data of the two groups were compared and analyzed.Results There were statistical differences between the two groups in preoperative Killip grading, rate of intra-aortic balloon pump use, interval from myocardial infarction to operation, and the number of culprit artery (P<0.05). There was no statistical difference in other preoperative data, the cardiopulmonary bypass time, aortic cross-clamping time, postoperative hospital stay or in-hospital death rate between the two groups (P＞0.05). No residual shunt occurred in the modified group, and the difference was statistically significant compared with the traditional group (P=0.038). There was no statistical difference in other complications between the two groups (P＞0.05). The median follow-up time was 4 years. Two patients in the traditional group and one in the modified group died during follow-up. The follow-up cardiac function grading of patients in the modified group was statistically different from that in the traditional group (P=0.023). Conclusion The perioperative mortality of ventricular septal rupture after myocardial infarction is high, but the long-term effect is satisfactory. Surgical repair combining an occluder and a patch is a safe and effective treatment for ventricular septal rupture, which can effectively reduce postoperative residual shunt.
ObjectiveTo investigate the course of the idiopathic macular hole (IMH) clinically diagnosed as at stage Ⅰ-Ⅳ by optical coherence tomography (OCT), and analyze the relationship between the posterior vitreous detachment (PVD) and the course of IMH. MethodsHadn′t undergone any operation, periodical OCT were performed on 72 eyes of 58 patients with IMH at stage Ⅰ-Ⅳ confirmed by Gass standard and the features of OCT images.ResultsThe longest follow-up period was 43 months (average 13.4 months), and the examine times of OCT on each eye were between twice to 10 times (average 4.7 times). During the followup period, 23 eyes were in stage I in which 9 (39.1%) developed to stage II and 2 had recovered normal curve of fovea after PVD; 19 were in stage II in which 13 (68.4%) developed to Ⅲ-Ⅳ and 1 had closed hole after PVD; 11 were in stage III in which 5 (45.5%) developed to stage IV and 1 had partly closed hole 12 months later. The images of OCT showed that the process of macular hole was consistent with the course that vitreous depart from retina from the circumference of fovea till entire posterior detachment.Fifteen affected eyes in this series of patients had undcrygong surgical treatment due to serious progression of IMH in follow-up period. ConclusionsThere is a close relationship between the formation and development of macular hole and the occurrence of PVD. OCT can show the progress of the macular hole directly and offer an important technique in diagnosis, classification and surgical treatment of IMH. (Chin J Ocul Fundus Dis, 2005,21:79-82)
Myopic foveoschisis (MF) has mild early symptoms, however, its course is progressive. When the secondary macular detachment or macular hole occurs, it can cause severe vision loss. Therefore, it is generally believed that MF patients should undergo surgical intervention early after the onset of symptoms to prevent them from further developing into a macular hole or macular hole retinal detachment.It is generally believed that the traction of the vitreous cortex and posterior scleral staphyloma to the retina plays an important role in the occurrence and development of MF. The operation mode is divided into vitreoretinal surgery and macular buckling, the former release the retinal traction via the vitreous body and the latter reattaches the retina via the extrascleral approach. There is no consensus on whether to perform internal limiting membrane peeling and gas tamponade in vitreoretinal surgery and the fovea-sparing internal limiting membrane peeling has become a hot topic in recent years. Compared with vitreoretinal surgery, macular buckling can release the traction of the retina caused by posterior scleral staphyloma, but it cannot relieve the traction in the tangential direction of the retina. Vitreoretinal surgery and extrascleral surgery seems to make up the shortcomings of both, however, the effect of treatment on patients still needs further verification. In clinical work, it is necessary to conduct individualized analysis of MF patients, weigh the advantages and disadvantages of each operation, and choose the most suitable operation mode for patients with different conditions. In the future, the emphasis of our work is to develop operation mode with great curative effect and less complications.

Surgical treatments for macular hole and rhegmatogenous retinal detachment are the most common and principle procedures for vitreoretinal specialists. The surgical success rate reached 95.0% and above for vitrectomy, macular surgeries with ILM peeling, or local/total scleral buckling. However, the postoperative visual function recovery is nowhere near good enough. Specialists must pay more attention to the visual function recovery of those patients. Postoperative macular anatomical and functional rehabilitation for macular hole and scleral buckling procedures need a long period of time. At present, the postoperative visual acuity for macular hole depends on many factors, such as macular hole closure conditions, surgical procedures, microsurgical invasive ways, skills of membrane peeling, usage of dye staining, and tamponade material choice. It also depends on residual subretinal fluid under macular area for patients received scleral buckling. It is important for us to investigate these factors affecting recovery of macular anatomy and function, and thus develop some drugs to improve the macular function recovery.
ObjectiveTo investigate the factors correlated with the visual outcome of idiopathic macular holes (IMH) after vitreoretinal surgery. MethodsA total of 57 eyes of 57 patients with IMH were included. There were 43 females (43 eyes) and 14 male (14 eyes), mean age was (60.46±4.79) years. All the eyes underwent best corrected visual acuity (BCVA), slit-lamp microscope, three-mirror contact-lens and optical coherence tomography (OCT) examinations. BCVA were examined with interactional visual chart and recorded with logarithm of the minimum angle of resolution (logMAR) acuity. The minimum diameter and base diameter of macular holes and central retinal thickness (CRT) were detected by OCT. The average logMAR BCVA of 57 eyes was 0.98±0.41. The minimum diameter and base diameter of macular holes were (479.53±164.16) μm and (909.14±278.65) μm. All the patients underwent pars plana vitrectomy combined with phacoemulsification cataract extraction and intraocular lens implantation. The mean follow-up period was (173.44±147.46) months. The relationships between final BCVA and these parameters were examined by single and multiple regression analysis. The valuable influence factors were filtrated and formulated using multiple linear regression models. ResultsAt the final follow-up, the logMAR BCVA of 57 eyes was 0.44±0.31, the CRT was (158.79±86.96) μm. The final BCVA was positive related to minimum diameter of macular holes and preoperative BCVA (r=0.420, 0.448; P=0.001, 0.000), negative related to postoperative CRT (r=-0.371, P=0.004). There was no relationship between the final BCVA and base diameter of macular holes, age and follow-up (r=0.203, -0.015, 0.000; P=0.130, 0.913, 0.999). The incidence of preoperative BCVA for postoperative BCVA was bigger than preoperative minimum diameter of macular holes (P=0.008, 0.020). ConclusionThe preoperative minimum diameter of macular holes and BCVA are related to postoperative BCVA in IMH eyes.
