  • Predictive factors of new-onset conduction abnormalities after transcatheter aortic valve replacement in patients with bicuspid aortic valve: a meta-analysis

    ObjectiveTo systematically review the predictive factors of new-onset conduction abnormalities(NOCAs) after transcatheter aortic valve replacement (TAVR) in bicuspid aortic valve (BAV) patients. MethodsThe CNKI, VIP, WanFang Data, PubMed, Cochrane Library and EMbase databases were electronically searched to collect the relevant studies on NOCAs after TAVR in patients with BAV from inception to December 5, 2022. Two researchers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.4 software. ResultsSix studies involving 758 patients with BAV were included. The results of the meta-analysis showed that age (MD=−1.48, 95%CI −2.73 to −0.23, P=0.02), chronic kidney disease (OR=0.14, 95%CI 0.06 to 0.34, P<0.01), preoperative left bundle branch block (LBBB) (OR=2.84, 95%CI 1.11 to 7.23, P=0.03), membranous septum length (MSL) (MD=0.93, 95%CI 0.05 to 1.80, P=0.04), implantation depth (ID) (MD=−2.06, 95%CI −2.96 to −1.16, P<0.01), the difference between MSL and ID (MD=3.05, 95%CI 1.92 to 4.18, P<0.01), and ID>MSL (OR=0.27, 95%CI 0.15 to 0.49, P<0.01) could be used as predictors of NOCAs. ConclusionCurrent evidence shows that age, chronic kidney disease, LBBB, MS, ID, the difference between MSL and ID, and ID>MSL could be used as predictors of NOCAs. Due to the limited quantity and quality of included studies, more high-quality studies are required to verify the above conclusion.

  • Application of prenatal multi-disciplinary team clinics in fetal developmental abnormalities

    Objective To explore the application of multi-disciplinary team (MDT) clinics in fetal developmental abnormalities. Methods A retrospective analysis method was used to collect case data of fetal developmental abnormalities and completion of prenatal MDT clinics diagnosis and treatment in pregnant women who were registered in the Department of Obstetrics of West China Second Hospital, Sichuan University between December 2021 and November 2022. The situation of pregnant women and fetuses was summarized and analyzed. Results There were 19362 registered pregnant women, of which 1125 (5.8%) had abnormal fetal development. Among them, 272 (24.2%) received prenatal MDT clinics diagnosis and treatment. Fetal developmental abnormalities were mainly characterized by structural abnormalities (208 cases, 76.5%), with the top three being central nervous system abnormalities, circulatory system abnormalities, and multiple malformations. There were 202 pregnant women who continue to conceive, and 70 cases had undergone induced labor, with an induced labor rate of 25.7%. The top three main causes of induced abortion were multiple malformations, central nervous system abnormalities, and circulatory system abnormalities. After prenatal MDT clinics diagnosis and treatment, the diagnosis of fetal developmental abnormalities in 46 pregnant women were corrected. Conclusion Prenatal MDT clinics are helpful for the early comprehensive evaluation of fetal developmental abnormalities and the determination of diagnosis and treatment plans.

  • Clinical Analysis for Reason and Treatment Strategy of Gallbladder Muddy Stones after Cholecystolithotomy

    ObjectiveTo discuss the reason and treatment strategy of gallbladder muddy stones after cholecysto-lithotomy. MethodsThe clinical data of 62 patients with gallbladder muddy stones after cholecystolithotomy who were treated in our hospital from December 2008 to December 2014 was analyzed retrospectively. ResultsThere were 43 patients without any symptom and 19 patients with acute cholecystitis in 62 patients. Four patients were diagnosed with septation gallbladder, 6 patients with long and tortuous cystic duct, 3 patients with calculus of cystic duct, 4 patients with common bile duct stones, 39 patients with periampullary diverticula, 18 patients with pancreaticobiliary maljunction, 6 patients with duodenal papilla stenosis, 29 patients with duodenal papillitis, and 3 patients with duodenal papilla adenocarcinoma. Two patients were treated with laparoscopic cholecystectomy (LC), 1 patient with endoscopic sphincterotomy (EST) /endoscopic balloon dilation (EPBD) and LC, 1 patient with percutaneous transhepafic gallbladder drainage (PTGD) and open cholec-ystectomy, 14 patients with PTGD and EST/EPBD, 1 patient with PTGD and hepatocholangioplasty with the use of gallbladder (HG), 34 patients with EST/EPBD, 3 patients with EST/EPBD and endoscopic biliay metal stent drainage (EBMSD), 5 patients with HG, and 1 patient with EST/EPBD and HG. The gallbladder muddy stones disappeared after operations in 55 patients with gallbladder reserved, and gallbladder ejection fraction increased from (42±12) % to (59±16) %. Of the 62 patients, 53 patients were followed up for 6 months to 6 years (the median time was 3.6-year). During the follow-up period, 3 patients were diagnosed with gallbladder stones, 2 patients with common bile duct stones, and 2 patients with intrahepatic and extrahepatic bile duct stones. ConclusionBile efferent tract obstruction is the important reason for the formation of gallbladder stones. HG, EST, and balloon expansion are the efficient methods to resolve the bile efferent tract obstruction.

  • Optical coherence tomography observation of retinal paravascular abnormalities in young myopic population

    ObjectiveTo observe the abnormal clinical manifestations of retinal blood vessels and the characteristic image characteristics of optical coherence tomography (OCT) in young myopia. MethodsA case observation study. From July to December 2020, 523 young patients with different myopia refractive powers who were treated in Department of Ophthalmology of The Second Hospital of Hebei Medical University were included in the study. Among them, 277 were males and 246 were females; the median age was 19.0 (5.0) years. All the affected eyes underwent best corrected visual acuity (BCVA), frequency domain OCT (SD-OCT) examination and axial length (AL) measurement. The BCVA examination was performed using the Snellen eye chart. The median myopia refractive power of the affected eye was 5.00 (3.25) D. Among them, low myopia, moderate myopia, and high myopia were 227, 405, and 414 eyes, respectively. The average AL of the affected eye was 25.6±2.8 mm. The frequency domain OCT instrument was used to scan the temporal side of the retina, the upper and lower nasal vascular arches and the macular fovea radially. The images of retinal vascular cysts, microfolds, and lamellar hole were acquired and stored. The prevalence, composition ratio, distribution rule and OCT imaging characteristics of retinal paravascular abnormalities were observed and analyzed. The distribution of paravascular abnormalities in the retina was compared by the χ2 test; the age, refractive power, and AL of different paravascular abnormalities were compared by the K-W rank sum test. ResultsOf the 1046 different diopters of myopic eyes, there were 227 eyes in mild myopia, 405 eyes in moderate myopia and 414 eyes in high myopia. Retinal paravascular abnormalities were detected by SD-OCT in 40 eyes (3.8%,40/1046). The prevalence of retinal paravascular abnormalities in moderate myopia was 0.7% (3/405) and high myopia was 8.9% (37/414). No retinal paravascular abnormalities were observed in mild myopia.Retinal paravascular cysts in 40 eyes (3.8%, 40/1046), retinal paravascular microfolds in 28 eyes (2.7%, 28/1046) and retinal paravascular lamellar holes in 13 eyes (1.2%, 13/1046). Of 40 eyes with retinal paravascular abnormalities, retinal paravascular cysts in all 40 eyes (100.0%, 40/40), retinal paravascular microfolds in 28 eyes (70.0%, 28/40) and retinal paravascular lamellar holes in 13 eyes (32.5%, 13/40). Twelve eyes with simple cyst cavity (30.0%, 12/40); 15 eyes were with cyst cavity with micro-wrinkles (37.5%, 15/40); 13 eyes were with cyst cavity, micro-wrinkles and lamellar holes (32.5%, 13/40). The temporal vascular arch retinal paravascular cysts (χ2=25.664), microfolds (χ2=14.973), and lamellar holes (χ2=13.499) were significantly more than those on the nasal side, and the difference was statistically significant (P<0.001). ConclusionsThe total prevalence of retinal paravascular abnormalities in young myopia is 3.8%; it can occur in both moderate and high myopia. The paravascular cyst may be the earliest pathology of paravascular abnormalities in the retina. The three paravascular abnormalities are mostly distributed along the temporal arch of the retina.
