Iridoschisis misdiagnosed as acute angle-closure glaucoma:a case report and literature review

We present the case of a patient with iridoschisis complicated with cataract,peripheral anterior synechiae(PAS),secondary glaucoma,and corneal endothelial damage.The patient was initially misdiagnosed with acute angle-closure glaucoma.Iridoschisis is a rare condition characterized by the splitting of the iris into two layers:the anterior layer breaks down into fibers,floating freely in the anterior chamber with a“shredded wheat”appearance.

Micropulse transscleral laser therapy for secondary angle-closure glaucoma in nanophthalmos: a case report

Dear Editor,The choice of surgical intervention for nanophthalmos patients with secondary angle-closure glaucoma poses a challenging decision for ophthalmologists.Because nanophthalmos patients who have undergone filtration surgery or other intraocular procedures are more susceptible to severe complications,including choroidal effusion,malignant glaucoma,and explosive choroidal hemorrhage,all of which can lead to vision loss[1].This dilemma is particularly pronounced in patients with shorter axial lengths.Micropulse transscleral laser therapy(M-TLT),also known as micropulse transscleral cyclophotocoagulation(MP-TSCPC),is a nonincisional laser therapy surgery for glaucoma[2].In 2015,Golan and Kurtz[3]were the first to report four patients with secondary angle-closure glaucoma in nanophthalmos with axial lengths ranging between 17 and 19 mm(mean 18 mm)who were successfully treated with M-TLT,and choroidal detachment was observed in all patients(recovery spontaneously in two patients and recovery after systemic steroid treatment in the other two),of which two had a slight decrease in visual acuity.

Production induced fracture closure of deep shale gas well under thermo-hydro-mechanical conditions

Deep shale gas reservoirs have geological characteristics of high temperature,high pressure,high stress,and inferior ability to pass through fluids.The multi-stage fractured horizontal well is the key to exploiting the deep shale gas reservoir.However,during the production process,the effectiveness of the hydraulic fracture network decreases with the closure of fractures,which accelerates the decline of shale gas production.In this paper,we addressed the problems of unclear fracture closure mechanisms and low accuracy of shale gas production prediction during deep shale gas production.Then we established the fluid—solid—heat coupled model coupling the deformation and fluid flow among the fracture surface,proppant and the shale matrix.When the fluid—solid—heat coupled model was applied to the fracture network,it was well solved by our numerical method named discontinuous discrete fracture method.Compared with the conventional discrete fracture method,the discontinuous discrete fracture method can describe the three-dimensional morphology of the fracture while considering the effect of the change of fracture surface permeation coefficient on the coupled fracture—matrix flow and describing the displacement discontinuity across the fracture.Numerical simulations revealed that the degree of fracture closure increases as the production time proceeds,and the degree of closure of the secondary fractures is higher than that of the primary fractures.Shale creep and proppant embedment both increase the degree of fracture closure.The reduction in fracture surface permeability due to proppant embedment reduces the rate of fluid transfer between matrix and fracture,which has often been overlooked in the past.However,it significantly impacts shale gas production,with calculations showing a 24.7%cumulative three-year yield reduction.This study is helpful to understand the mechanism of hydraulic fracture closure.Therefore,it provides the theoretical guidance for maintaining the long-term effectiveness of hydraulic fractures.

Acute primary angle closure during the Omicron outbreak

AIM:To investigate Omicron’s impact on clinical presentation of acute primary angle closure(APAC)in China.METHODS:A consecutive case series with historical controls was conducted at Shenzhen Eye Hospital,the largest specialized hospital in Shenzhen,China.Medical records from a two-month period during the Omicron pandemic(December 1,2022,to January 31,2023)were compared with records from two control groups(12/2018–1/2019 and 12/2021–1/2022)before pandemic.Patients with APAC were included,and the prevalence of APAC and demographic characteristics in Omicron-infected and noninfected patients were compared.RESULTS:Seventy-one(23.43%)out of 303 patients were diagnosed with APAC in the pandemic cohort,which was 2.98 and 2.61 times higher than that in control cohorts(7.87%in 2019,8.96%in 2022,P<0.001).The pandemic cohort has significantly higher Omicron-infected rate(78.87%vs 0 vs 0;P<0.001),lower proportion of glaucoma history(16.90%vs 42.86%vs 41.67%,P=0.005),higher surgical rate(95.77%vs 83.33%vs 78.57%,P=0.024),higher total medical costs and larger pupil diameter(5.63±0.15 vs 4.68±0.15 vs 4.69±0.22 mm,P<0.01).In 83%Omicron-infected patients,ocular symptoms appeared within 3d after systemic symptoms onset.In multivariate analysis,Omicron infection(P<0.001)was the only independent predictor of pupil diameter.CONCLUSION:In the Omicron epidemic in China,there is an increase of prevalence and severity of APAC,particularly focusing on the first 3d following infection.

Transcatheter Closure of Postoperative Residual Atrial or Ventricular Septal Shunts in Patients with Congenital Heart Disease

Background:Transcatheter closure(TCC)has emerged as the preferred treatment for selected congenital heart disease(CHD).While TCC offers benefits for patients with postoperative residual shunts,understanding its mid-and long-term efficacy and safety remains crucial.Objective:This study aims to assess the mid-and long-term safety and efficacy of TCC for patients with residual atrial or ventricular septal shunts following CHD correction.Methods:In this consecutive retrospective study,we enrolled 35 patients with residual shunt who underwent TCC or surgical repair of CHD between June 2011 to October 2022.TCC candidacy was determined based on established criteria.Echocardiography and electrocardiogram were conducted during the perioperative period and continued as part of long-term follow-up.Results:Among the patients,5(14.3%)exhibited interatrial shunt-ing,while 30(85.7%)had interventricular shunting.TCC was successfully implemented in 33 of 35 patients,with exceptions in two cases of post-ventricular septal defect repair due to anatomical challenges involving the shape and aortic angulation.This resulted in a TCC success rate of 94.3%.Trace residual shunt was detected in two interventricular shunting cases and a mild residual shunt in one interventricular shunting case;all resolved by the three-month follow-up after TCC.Minor complications included one hematoma at the puncture site and one transient junctional rhythm during the perioperative period.During a median follow-up of 73 months,there were no instances of residual shunt,device embolization,occluder displacement,valve insufficiency,malignant arrhythmia,infective endocarditis,death,or other serious complications.Conclusion:TCC is an effective and safe therapy for patients with residual atrial or ventricular septal shunts following CHD correction.Thesefindings support the consideration of TCC as the preferred treatment option for appropriate patient populations.

Clinical efficacy of endovascular revascularization combined with vacuum-assisted closure for the treatment of diabetic foot

BACKGROUND The diabetic foot is a common cause of disability and death,and comorbid foot infections usually lead to prolonged hospitalization,high healthcare costs,and a significant increase in amputation rates.And most diabetic foot trauma is complicated by lower extremity arteriopathy,which becomes an independent risk factor for major amputation in diabetic foot patients.AIM To establish the efficacy and safety of endovascular revascularization(ER)combined with vacuum-assisted closure(VAC)for the treatment of diabetic foot.METHODS Clinical data were collected from 40 patients with diabetic foot admitted to the Second Affiliated Hospital of Soochow University from April 2018 to April 2022.Diabetic foot lesions were graded according to Wagner’s classification,and blood flow to the lower extremity was evaluated using the ankle-brachial index test and computerized tomography angiography of the lower extremity arteries.Continuous subcutaneous insulin infusion pumps were used to achieve glycemic control.Lower limb revascularization was facilitated by percutaneous transluminal balloon angioplasty(BA)or stenting.Wounds were cleaned by nibbling debridement.Wound granulation tissue growth was induced by VAC,and wound repair was performed by skin grafting or skin flap transplantation.RESULTS Of the 35 cases treated with lower limb revascularization,34 were successful with a revascularization success rate of 97%.Of these,6 cases underwent stenting after BA of the superficial femoral artery,and 1 received popliteal artery stent implantation.In the 25 cases treated with infrapopliteal artery revascularization,39 arteries were reconstructed,7 of which were treated by drug-coated BA and the remaining 32 with plain old BA.VAC was performed in 32 wounds.Twenty-four cases of skin grafting and 2 cases of skin flap transplantation were performed.Two patients underwent major amputations,whereas 17 had minor amputations,accounting for a success limb salvage rate of 95%.CONCLUSION ER in combination with VAC is a safe and effective treatment for diabetic foot that can significantly improve limb salvage rates.The use of VAC after ER simplifies and facilitates wound repair.

Impact of Atrial Septal Defect Closure on Mortality in Older Patients

Background:Atrial septal defect(ASD)is a common form of adult congenital heart disease that can lead to long-term adverse outcomes if left untreated.Early closure of ASD has been associated with excellent outcomes and lower complication rates.However,there is limited evidence regarding the prognosis of ASD closure in older adults.This study aims to evaluate the mortality rates in older ASD patients with and without closure.Methods:A retrospective cohort study was conducted on patients aged 40 years or older with ASD between 2001 and 2017.Patients were followed up to assess all-cause mortality.Univariable and multivariable analyses were performed to identify the predictors of mortality.A p-value of<0.05 was considered statistically significant.Results:The cohort consisted of 450 patients(mean age 56.6±10.4 years,77.3%female),with 66%aged between 40 and 60 years,and 34%over 60 years.Within the cohort,299 underwent ASD closure(201 with transcatheter and 98 with surgical closure).During the median follow-up duration of 7.9 years,51 patients died.The unadjusted cumulative 10-year rate of mortality was 3%in patients with ASD closure,and 28%in patients without ASD closure(log-rank p<0.001).Multivariable analysis revealed that age(hazard ratio[HR]1.04,95%confidence interval[CI]1.006–1.06,p=0.01),NYHA class(HR 2.75,95%CI 1.63–4.62,p<0.001),blood urea nitrogen(BUN)(HR 1.07,95%CI 1.03–1.12,p<0.001),right ventricular systolic pressure(RVSP)(HR 1.07,95%CI 1.003–1.04,p=0.01),and lack of ASD closure(HR 15.12,95%CI 5.63–40.59,p<0.001)were independently associated with mortality.Conclusion:ASD closure demonstrated favorable outcomes in older patients.Age,NYHA class,BUN,RVSP,and lack of ASD closure were identified as independent factors linked to mortality in this population.

Intraocular pressure and gonioscopic findings in primary angle-closure disease in India—a big data study

AIM:To describe the gonioscopic profile and intraocular pressure(IOP)in primary angle-closure(PAC)disease in patients presenting to a tertiary eye care network in India.METHODS:A cross-sectional hospital-based study that included 31484 new patients presenting between 2011 and 2021.Patients with a clinical diagnosis of PAC/suspect/glaucoma were included.The data was collected from an electronic medical record system.RESULTS:PAC glaucoma(PACG)(47.55%)was the most common diagnosis followed by PAC(39.49%)and PAC suspect(PACS;12.96%).Female preponderance(54.6%)was noted with higher mean age at presentation among males(P<0.0001).PACS and PAC showed the highest prevalence in 6th decade but PACG was higher at 7th decade.The probability of angle opening was 95.93%,90.32%and 63.36%in PACS,PAC and PACG eyes respectively post peripheral iridotomy(PI).Plateau iris syndrome(PIS)was noted in 252 eyes and all showed post dilated rise of IOP.A post dilated IOP rise was also noted with 8.86%,33.95%and 57.19%eyes with PACS,PAC and PACG respectively with IOP rise between 6-8 mm Hg across the disease spectrum.CONCLUSION:The superior quadrant is the narrowest angle and difficult to open with indentation and post PI.The probability of angle opening is less in PIS especially the complete variety along with post dilated IOP rise.The post dilated IOP rise in angle closure eyes warrants a careful dilatation,especially with PIS.

Early postoperative complications after transverse colostomy closure,a retrospective study

BACKGROUND Ostomy is a common surgery usually performed to protect patients from clinical symptoms caused by distal anastomotic leakage after colorectal cancer(CRC)surgery and perforation or to relieve intestinal obstruction.AIM To analyze the complications after transverse colostomy closure.METHODS Patients who underwent transverse colostomy closure from Jan 2015 to Jan 2022 were retrospectively enrolled in a single clinical center.The differences between the complication group and the no complication group were compared.Logistic regression analyses were conducted to find independent factors for overall complications or incision infection.RESULTS A total of 102 patients who underwent transverse colostomy closure were enrolled in the current study.Seventy(68.6%)patients underwent transverse colostomy because of CRC related causes.Postoperative complications occurred in 30(29.4%)patients and the most frequent complication occurring after transverse colostomy closure was incision infection(46.7%).The complication group had longer hospital stays(P<0.01).However,no potential risk factors were identified for overall complications and incision infection.CONCLUSION The most frequent complication occurring after transverse colostomy closure surgery in our center was incision infection.The operation time,interval from transverse colostomy to reversal,and method of anastomosis might have no impact on the postoperative complications.Surgeons should pay more attention to aseptic techniques.

Colon perforation with severe peritonitis caused by erotic toy insertion and treated using vacuum-assisted closure:A case report

BACKGROUND Colorectal foreign bodies are commonly encountered during surgery.They are frequently observed in men 20 to 90 years of age and have bimodal age distribution.Surgical management is necessary for cases of rectal perforation.However,surgical site infections are the most common complications after colorectal surgery.CASE SUMMARY We discuss a case of rectal perforation in a patient who presented to our hospital 2 d after its occurrence.The perforation occurred as a result of the patient inserting a sex toy in his rectum.Severe peritonitis was attributable to delayed presentation.CONCLUSION Vacuum-assisted closure was performed to treat the wound,which healed well after therapy.No complications were noted.

Micro-power negative pressure wound technique reduces risk of incision infection following loop ileostomy closure

BACKGROUND Prophylactic loop ileostomy is an effective way to reduce the clinical severity of anastomotic leakage following radical resection of rectal cancer.Incisional surgical site infection(SSI)is a common complication after ileostomy closure.AIM To evaluate the efficacy and safety of the micro-power negative pressure wound technique(MPNPWT)in preventing incisional SSI.METHODS This was a prospective,randomized controlled clinical trial conducted at a single center.A total of 101 consecutive patients who underwent ileostomy closure after rectal cancer surgery with a prophylactic ileostomy were enrolled from January 2019 to December 2021.Patients were randomly allocated into an MPNPWT group and a control group.The MPNPWT group underwent intermittent suturing of the surgical incision with 2-0 Prolene and was covered with a micro-power negative pressure dressing.The surgical outcomes were compared between the MPNPWT(n=50)and control(n=51)groups.Risk factors for incisional SSI were identified using logistic regression.RESULTS There were no differences in baseline characteristics between the MPNPWT(n=50)and control groups(n=51).The incisional SSI rate was significantly higher in the control group than in the MPNPWT group(15.7%vs 2.0%,P=0.031).However,MPNPWT did not affect other surgical outcomes,including intra-abdominal complications,operative time,and blood loss.Postoperative hospital stay length and hospitalization costs did not differ significantly between the two groups(P=0.069 and 0.843,respectively).None of the patients experienced adverse effects of MPNPWT,including skin allergy,dermatitis,and pain.MPNPWT also helped heal the infected incision.Our study indicated that MPNPWT was an independent protective factor[odds ratio(OR)=0.005,P=0.025)]and diabetes was a risk factor(OR=26.575,P=0.029)for incisional SSI.CONCLUSION MPNPWT is an effective and safe way to prevent incisional SSI after loop ileostomy closure.

Clinical Value of Echocardiographic Screening and Dynamic Observations for Ductus Arteriosus Closure in Newborns

Objective:To explore and analyze the clinical value of echocardiography screening and dynamic observation for ductus arteriosus closure in newborns.Methods:The study was conducted from August 2022 to December 2023.500 newborns who were admitted to our hospital were selected as research subjects for this study(Kunming Tongren Hospital).All subjects underwent echocardiography to determine the severity of patent ductus arteriosus(PDA).The inner diameter of the pulmonary artery was measured,and the pulmonary artery pressure was estimated through tricuspid regurgitation.If the patient had high pulmonary artery pressure,elective closure surgery was performed.Results:Among the 500 subjects,448 cases of ductus arteriosus closure and 52 cases of PDA were detected by echocardiography,including 23 cases of simple PDA,15 cases with patent foramen ovale,11 cases with atrial septal defect,1 case with muscular ventricular septal defect,1 case with tricuspid valve prolapse,and 1 case with tricuspid valve chordae tendineae rupture.After symptomatic treatment and intervention,their echocardiogram results were reviewed and no abnormalities were found.All measurement results of children with PDA combined with pulmonary hypertension were better than before treatment(P<0.05).Conclusion:Echocardiography is a fast,accurate,and reliable non-invasive imaging examination technology.It can significantly improve congenital heart disease detection rate in infants and young children.Early intervention based on the examination results can dramatically improve the quality of life of infants and young children with PDA.

Efficacy of Combined Phacoemulsification and Goniosynechialysis in the Treatment of Patients with Primary Angle Closure Disease and Concomitant Cataract at Preah Ang Duong Hospital in Cambodia

Background: Goniosynechialysis is a surgical procedure that has been shown to slow the progression of glaucoma in oriental eyes with chronic angle closure glaucoma. This procedure was successful in 80% of cases, and the peripheral anterior syenchiae did not exist until one year later. Nonetheless, there is little evidence of its efficacy in our context. Our study aims to investigate the efficacy of goniosynechialysis during phacoemulsification in patients with primary angle closure disease and concomitant cataract. Methods: This was an observational, prospective study. The intra-ocular pressure, need for anti-glaucoma drugs, visual acuity, the extent of synechiae, anterior chamber depth, surgical success rate, and other indicators were monitored for at least three months following surgery. Results: This study included 114 patients (118 eyes), 61 with chronic angle closure glaucoma (51.69%), 33 with primary angle closure (27.97%), and 24 with acute attack angle closure (20.34%), who were surgically treated with phacoemulsification and goniosynechialysis (Phaco-GSL). The mean intra-ocular pressure had significantly decreased three months after surgery (pre- vs post-op: 22.04 ± 10.86 vs 15.41 ± 6.06 mmHg, p-value p-value p-value p-value p-value Conclusion: Regardless of the type of glaucoma, combined phacoemulsification-goniosynechialysis is effective in lowering pressure, restoring vision, reducing the need for anti-glaucoma drugs, and preventing the synechial recurrence. Success was higher in eyes with less extensive synechiae. Phaco-GSL is safe and effective in the treatment of primary angle closure diseases with co-existing cataract.

ALA reverses ABA-induced stomatal closure by modulating PP2AC and SnRK2.6 activity in apple leaves

5-Aminolevulinic acid(ALA),known as a new natural plant growth regulator,can reverse abscisic acid(ABA)-induced stomatal closure.The protein phosphatase 2A(PP2A)played an important role in regulation of stomatal movement by ALA and ABA;however,the underlying molecular mechanisms remain unclear.Here,we report that ALA promotes MdPP2A activity and gene expression in the leaf epidermis of apple(Malus×domestica Borkh.),and expression of the catalytic subunit MdPP2AC was most significantly correlated with stomatal aperture.Western blotting showed that ALA enhanced MdPP2AC protein abundance and phosphorylation.Y2H(yeast two hybrid),FLC(firefly luciferase complementation imaging)and BiFC(Bimolecular fluorescence complementation)assays showed that MdPP2AC interacted with several other MdPP2A subunits as well as MdSnRK2.6(Sucrose non-fermenting 1-related protein kinase 2.6),and the latter interaction was further verified by pull-down and MST(microscale thermophoresis)assays.ALA downregulated ABA-induced MdSnRK2.6 gene expression,kinase activity,and protein phosphorylation.In transiently transgenic apple leaves,OE-MdPP2AC promoted stomatal aperture by reducing Ca^(2+)and H_(2)O_(2) levels but increasing flavonol levels in guard cells.Conversely,OE-MdSnRK2.6 induced stomatal closure by increasing Ca^(2+)and H2O2 but reducing flavonols.Partial silencing of these genes had opposite effects on Ca^(2+),H_(2)O_(2),flavonols,and stomatal movement.Application of exogenous ALA stimulated PP2A activity,which promoted SnRK2.6 dephosphorylation and lower kinase activity in wild-type and transgenic apple leaves.We therefore propose that PP2AC,which dephosphorylates SnRK2.6 and represses its enzyme activity,mediates ALA signaling to inhibit ABA-induced stomatal closure in apple leaves.

Loop Closure Detection via Locality Preserving Matching With Global Consensus

A critical component of visual simultaneous localization and mapping is loop closure detection(LCD),an operation judging whether a robot has come to a pre-visited area.Concretely,given a query image(i.e.,the latest view observed by the robot),it proceeds by first exploring images with similar semantic information,followed by solving the relative relationship between candidate pairs in the 3D space.In this work,a novel appearance-based LCD system is proposed.Specifically,candidate frame selection is conducted via the combination of Superfeatures and aggregated selective match kernel(ASMK).We incorporate an incremental strategy into the vanilla ASMK to make it applied in the LCD task.It is demonstrated that this setting is memory-wise efficient and can achieve remarkable performance.To dig up consistent geometry between image pairs during loop closure verification,we propose a simple yet surprisingly effective feature matching algorithm,termed locality preserving matching with global consensus(LPM-GC).The major objective of LPM-GC is to retain the local neighborhood information of true feature correspondences between candidate pairs,where a global constraint is further designed to effectively remove false correspondences in challenging sceneries,e.g.,containing numerous repetitive structures.Meanwhile,we derive a closed-form solution that enables our approach to provide reliable correspondences within only a few milliseconds.The performance of the proposed approach has been experimentally evaluated on ten publicly available and challenging datasets.Results show that our method can achieve better performance over the state-of-the-art in both feature matching and LCD tasks.We have released our code of LPM-GC at https://github.com/jiayi-ma/LPM-GC.

Is fascial closure required for a 12-mm trocar?A comparative study on trocar site hernia with long-term follow up

BACKGROUND Despite the infrequency of trocar site hernias(TSHs),fascial closure continues to be recommended for their prevention when using a≥10-mm trocar.AIM To identify the necessity of fascial closure for a 12-mm nonbladed trocar incision in minimally invasive colorectal surgeries.METHODS Between July 2010 and December 2018,all patients who underwent minimally invasive colorectal surgery at the Minimally Invasive Surgery Unit of Siriraj Hospital were retrospectively reviewed.All patients underwent cross-sectional imaging for TSH assessment.Clinicopathological characteristics were recorded.Incidence rates of TSH and postoperative results were analyzed.RESULTS Of the 254 patients included,70(111 ports)were in the fascial closure(closed)group and 184(279 ports)were in the nonfascial closure(open)group.The median follow up duration was 43 mo.During follow up,three patients in the open group developed TSHs,whereas none in the closed group developed the condition(1.1%vs 0%,P=0.561).All TSHs occurred in the right lower abdomen.Patients whose drains were placed through the same incision had higher rates of TSHs compared with those without the drain.The open group had a significantly shorter operative time and lower blood loss than the closed group.CONCLUSION Routine performance of fascial closure when using a 12-mm nonbladed trocar may not be needed.However,further prospective studies with cross-sectional imaging follow-up and larger sample size are needed to confirm this finding.

Sustainable and responsible mining through sound mine closure

This paper provides an overview of planning requirements,including regulatory,and implementation approaches for achieving ecologically sound reclamation and restoration of mines upon closure in the USA.Mine closure includes mined-out areas,decommissioning of plants and structures,and appropriate monitoring of post-mining land,water,and air resources.Although the discussion provides general guidelines,each mine closure site presents unique challenges.The overall chemical composition of coal and associated strata with mineable coal seams,structural characteristics of the deposit,weather patterns,environmental conditions,processing and scale of mining of the deposit,and public and private infrastructure must be considered.Future land use and water resource requirements are also important considerations.The planning and closure activities must ensure that the resultant site has the appropriate post-mining land and water resources use,and the site does not pose any future environmental and health and safety risks.These requirements suggest that closure activities should be integrated with the mining activity planning process from the start.This paper discusses mine closure issues and describes several practices for a surface coal mine in the Western USA.

Intermediate and Long-Term Follow-Up of Transcatheter Closure of Congenital Coronary Cameral Fistulas in Infants and Children:Experience from a Single Center

Background:Limited data are available regarding intermediate and long-term outcomes of transcatheter closure(TCC)of coronary cameral fistulas(CCFs)in the pediatric patients.Methods:All pediatric patients diagnosed with CCFs who were scheduled to undergo TCC between 2005 and 2019 were retrospectively enrolled in the study.Results:A total of 66 patients(median age:3.93 years,median weight:15 kg)underwent attempted TCC of CCFs.Immediate successful device implantation was achieved in 62 patients,and immediate complete occlusion was achieved in 44 patients(44/62%,71.0%).The closure procedure was waived in 2 patients due to anatomical factors.A total of 6 periprocedural complications occurred in 5 patients,including acute myocardial infarction(n=3),procedure-related death(n=1),device embolization(n=1),and rupture of tricuspid chordae tendineae(n=1).The acute procedural success rate was 89.4%(59/66),while the acute complication rate was 9.1%(6/66).Follow-up data were collected for 58(93.5%)out of 62 patients at a median of 9.3 years(range:3.0–15.7 years).10 adverse events occurred in 9 patients,including 5 follow-up complications(1 aortic valve perforation,1 coronary thrombosis,1 progressive aneurysmal dilation after reintervention,and 2 cases of new-onset tricuspid valve prolapse with significant regurgitation),and 5 closure failure with large residual shunts.The intermediate and long-term adverse event rate was 17.2%(10/58).The anatomical features associated with both acute and follow-up adverse events were large CCFs(p=0.005),and giant coronary artery aneurysms(CAAs)(p=0.029).Conclusions:TCC of CCFs in infants and children appears to be effective and is associated with a relatively low complication rate.Large CCFs and giant CAAs represent a higher risk of both acute and intermediate and long-term adverse events after closure.

A Meta-Analysis: Safety and Efficacy of Phacoemulsification with Goniosynechialysis versus Trabeculectomy for Acute Angle Closure Glaucoma in China

Aim: The aim is to evaluate the safety and efficacy of phacoemulsification with goniosynechialysis versus trabeculectomy in the treatment of acute angle closure glaucoma (AACG) systematically. Methods: From January 1, 2000 to August 31, 2022, we searched PubMed, Science Citation Index Database, China National Knowledge Infrastructure, and Wanfang Database for pertinent material about the treatment of AACG with various operations. The imported literature was carefully vetted using the inclusion and exclusion criteria, assessed for quality, and the raw data were retrieved and integrated into EndNoteX9. For the meta-analysis, STATA 16.0 and RevMan 5.3 were used as the tools. Results: The meta-analysis includes 20 clinical investigations in all, involving 1463 eyes. The quality of the literature was rated as excellent and the data homogeneity among the studies was excellent based on the various study types that were included in the literature. According to a meta-analysis, phacoemulsification with goniosynechialysis is superior to trabeculectomy for treating acute angle-closure glaucoma because it results in improved postoperative visual acuity, lower intraocular pressure, a broader anterior chamber depth, and fewer complications. Conclusion: If conditions allow, phacoemulsification in conjunction with goniosynechialysis performs better than trabeculectomy in terms of visual acuity, intraocular pressure, anterior chamber depth, and comorbidities.
