ABSTRACT
@#AIM: To observe the clinical effect of femtosecond laser-assisted phacoemulsification combined with goniosynechialysis in the management of acute angle-closure glaucoma with cataract.<p>METHODS:Retrospective study. From March 2019 to April 2021, 34 eyes of 29 acute angle-closure glaucoma with cataract patients were performed femtosecond laser-assisted phacoemulsification combined with goniosynechialysis. Best corrected visual acuity(BCVA), intraocular pressure(IOP), grading of chamber angle, central anterior chamber depth, corneal endothelial cell count and central corneal thickness were mesaured and analyzed preoperatively and at 1d, 1wk, 1mo.The postoperative complications were analyzed.<p>RESULTS: There was a statistically significant difference between preoperative and postoperative BCVA at 1mo(<i>Z</i>= -5.126, <i>P</i><0.01). IOP at 1d, 1wk and 1mo were 16.72±2.12mmHg, 13.73±1.68mmHg and 12.87±3.54mmHg respectively, which were different from 28.67±4.13mmHg before surgery(all<i> P</i><0.01). The range of atrial angle adhesion at 1mo after the surgery was significantly reduced compared with preoperative(<i>t</i>=21.32, <i>P</i><0.01). The depth of central anterior chamber, the open distance of atrial angle and the included angle of trabecular iris at 1mo after the surgery were significantly greater than preoperative(<i>t</i>= -3.37,-3.68, -5.61, all <i>P</i><0.01). There were no significant differences in corneal endothelial cell count and central corneal thickness(<i>P></i>0.05). Postoperative satisfaction was high without serious complications.<p>CONCLUSION:Femtosecond laser-assisted phacoemulsification combined with goniosynechialysis may be an effective treatment option for acute angle-closure glaucoma complicated with cataract, is safe, effective and has fewer complications.
ABSTRACT
[Objective]To retrospectively investigate the incidence,computed tomography(CT)manifestations and consequences of hemorrhagic pulmonary sheath(HPS)in Stanford A aortic dissection(AD)patients.[Methods]Institu-tional review board approval and informed consents were obtained.CT aortic angiography images of 188 consecutive acute Stanford A aortic dissection patients(mean age,59 years;range:29-78 years;136 males,52 females)were reviewed. CT images were interpreted by two independent radiologists.Clinical records were reviewed for outcomes of patients up to 30 days after the initial CT scan.[Results]18(9.6%)out of 188 patients had HPS.Right pulmonary artery was involved in 9(50%),left pulmonary artery in 2(11.1%)and both in 7(38.9%)of the 18 patients respectively.HPS extending along bronchovascular sheaths(TypeⅡ)was identified in 9(50%)of 18 patients,and 7(77.8%)of them had alveolar opacity around the thickened bronchovascular sheath. Within 30 days of follow-up,61.1%(11/18)patients died and 38.9%(7/18)patients survived with absorption of HPS.TypeⅡHPS was more prevalent in death group(7/11,63.6%) than survival group(2/7,28.6%),but not statistically significant(P=0.335).Patients in death group were more likely to have abdominal visceral arteries involvement(7/11,63.6%)than patients in survival group(0/7,0%)(P=0.010).[Conclusion]HPS was not a rare complication in patients with Stanford A AD.Abdominal visceral arteries involvement in-dicated poor short-term outcome in this study.
ABSTRACT
[Objective]We aimed to evaluate the role of contour-based registration in quantification of myocardial extracellular volume fraction(ECV)based on T1 mapping technique.[Methods]T1 mapping images of the basal,mid-cavity and apical short axis slices of 26 healthy volunteers(16 males and 10 females)were obtained before and after administration of contrast agent using Modified Look-Locker Inversion Recovery(MOLLI)on a 3.0T Magnetic Resonance Imaging system.ECV was calculated by routine method and registered method.For each slice,subjects were divided into the deformation subgroup and the control subgroup.Routine ECVs and registered ECVs were compared for each subgroup.[Results]Left ventricular deformation among T1 mapping images occurred in 16 subjects(61.5%). In all three slices, registered ECV maps had better image quality and more highest grade images than routine ECV maps. Routine ECVs[(26.81 ± 2.78)%,(25.38 ± 3.05)%,(28.66 ± 4.10)%]were statistically different from registered ECVs in global [(25.75±2.42)%,P=0.001],mid-cavity[(24.30±2.45)%,P=0.016]and apical slices[(27.22±3.38)%,P=0.010]. In deformation subgroups of all the 3 slices,registered ECVs were lower than routine ECVs with smaller SDs(P=0.038, 0.012,0.016).The apical ECVs were higher with larger SDs than the other two slices and the global ECVs(routine:F=4.799,P=0.004;registered:F=4.822,P=0.003).[Conclusions]Contour-based registration can improve the image qual-ity and precision of ECV quantification in cases with ventricular shape deformation among source images.
