Objective:To explore the application value and surgical experience of neuroendoscopic resection for pediatric patients with cerebellar tumors.Methods:This was a case series study.The clinical data and outcomes of 30 pediatric patients with cerebellar tumors treated through neuroendoscopic surgery in the Department of Neurosurgery, the Guizhou Hospital of Shanghai Children′s Medical Center and Guizhou Provincial People′s Hospital from January 2021 to January 2024 were retrospectively analyzed.Results:Twenty-six patients underwent total resection, 3 patients underwent subtotal resection, and 1 patient underwent biopsy.Postoperative pathological findings showed 9 cases of medulloblastoma, 3 cases of ependymoma, 17 cases of astrocytoma (5 cases of World Health Organization Grade Ⅰ, 3 cases of Grade Ⅱ, and 9 cases of Grade Ⅲ), and 1 case of cerebellar benign lesion.During the perioperative period, malignant arrhythmia occurred and induced death in 1 case, cerebellar mutism occurred in 12 cases, and ataxia occurred in 22 cases.During the 1-36 months of follow-up, 2 cases developed communicating hydrocephalus at the 2 nd and the 6 th month, respectively, and improved after ventriculoperitoneal shunt; cerebellar mutism was relieved to varying degrees after an average postoperative follow-up period of (115±23) days(46-194 days), and ataxia was alleviated after an average postoperative follow-up period of (127±42) days(27-173 days).Tumors relapsed in 5 cases during the last follow-up. Conclusions:Neuroendoscopy provides an alternative to the microscope for experienced operators to achieve the surgical exposure requirements during the resection of pediatric cerebellar vermis tumors.

Objective:To explore the treatments and outcomes of heart and kidney transplantation(HKTx)and summarize its management experiences.Methods:From October 2016 to October 2020, clinical data, treatment strategies and prognosis of 11 patients received HKTx were analyzed retrospectively.In 11HKTx cases, the ratio of male-to-female was 10∶1, the age(50.6±12.9)years and the preoperative body mass index(26.72±3.29)kg/m 2.The preoperative cardiac function was class Ⅳ and the preoperative left ventricular ejection fraction(29.40±4.48)%.All patients were in uremic state pre-operation and underwent regular dialysis.The mean duration of dialysis was 2.5(0.5-7.0)years, preoperative creatinine 753.5(434-1144)μmol/L and preoperative predictive glomerular filtration rate 5.59(3.93-17.23)ml/(min preop 2). Non-staged transplant was performed and donor heart and kidney were from the same donor.The median time of cold cardiac ischemia 2.75(2.5, 4.0)hours, the median time of cold renal ischemia 9(8.5, 15.0)hours and the median time from the end of heart transplantation to the beginning of kidney transplantation 2(1.0, 3.5)hours.The immunosuppressive regimen was a combination of tacrolimus, mycophenolate mofetil and methylprednisolone. Results:Normal cardiac function and renal function normalized in 9 cases.At Month 6 post-operation, the postoperative left ventricular ejection fraction was(57.55±2.51)%, creatinine 107.7(85-132)μmol/L and urine volume in 24h 1988(1800-2200)ml.The long-term survival time was 6-62 months.No such complications as infection or rejection occurred in 9 patients.The cardiac function was class Ⅰ at Month 6 post-operation.One patient died from pulmonary mucor infection at Month 4 post-operation.Another death was due to gastrointestinal fungal infection at Month 1 after HKTx.Conclusions:HKTx is an effective treatment for end-stage heart disease with renal failure.

Objective:To analyze the risk factors for postoperative pulmonary venous obstruction after correction of total anomalous pulmonary venous connection(TAPVC).Methods:We retrospectively reviewed all patients undergoing operative repair of TAPVC in our institution from December 2013 to January 2018. Patients with functionally univentricular circulations or atrial isomerism were excluded. Patients were divided into two groups according to whether there was pulmonary vein obstruction. The clinical variables of the two groups were compared. Variables for the multivariable analysis were chosen if there was statistical significance on univariable analysis.Results:145 patients were included, 91(63%) males, aged 4(2, 8)months and weight 5.5(4.5, 7.5)kg. Mean follow-up interval was(51±23) months. Postoperative obstruction developed in 27 patients(18.6%). The differences of anatomic type[supracardiac 18(67%) vs.59(50%), cardiac 4(15%) vs. 50(42%), infracardiac 3(11%) vs. 1(1%), mixed 2(7%) vs. 8(7%), P=0.003], preoperative obstruction[yes 19(70%) vs. 37(31%), no 8(30%) vs. 81(69%), P<0.001], associated cardiac lesions[yes 13(48%) vs. 27(23%), no 14(52%) vs. 91(77%), P=0.008] and bypass time[109(89, 129)min vs. 88(70, 110)min, P=0.002] between two groups were statistical significant. A multivariable model showed preoperative obstruction( P<0.001) and bypass time( P=0.009) were associated with postoperative obstruction. Conclusion:The incidence of pulmonary vein obstruction after correction of TAPVC was still high. If there was preoperative obstruction, or the bypass time was too long during operation, the surveillance of pulmonary vein obstruction should be strengthened after operation.

Objective To summarize the outcomes and clinical experience of combined heart and kidney transplantation.Methods The clinical data of one case of combined heart and kidney transplantation were retrospectively analyzed.The kidney transplant was completed immediately after the heart transplant.The immunosuppressive therapy strategies included tacrolimus,corticosteroids and mycophenolate mofetil.Results For heart transplantation,heart cold ischemia time was 200 min,aorta blocking time was 136 min,and extracorporeal circulation time was 201 min.The kidney was transplanted to the right iliac fossa after heart transplantation.The endotracheal tube was removed 15 h after surgery.The patient was transferred to the general ward on the 8th day after surgery.The patient was discharged from the hospital at 27th day after surgery,the renal function was normal and no activity was restricted.Conclusion Reasonable perioperative management and selection of surgical methods are the keys to the success of combined heart and kidney transplantation.

Objective To determine the effect of percutaneous transforaminal endoscopic surgery for elderly patients with lumbar spinal stenosis .Methods 80 senile patients with lumbar spinal stenosis were collected .According to the treatment methods ,they were divided into observation group and control group .40 patients in the observation group underwent percutaneous transforaminal endoscopic treatment ,40 patients in the control group underwent conventional surgical treatment .The operation time , blood loss , hospitalization time , X -ray exposure time , postoperative visual analogue scale( VAS) score and disability index score were compared between the two groups .Results Compared with the control group,the operative time[(61.7 ±12.4)min vs.(89.3 ±31.2)min],bleeding volume[(22.3 ± 7.2) mL vs.(192.7 ±49.1) mL] and hospitalization time [(5.3 ±1.7) d vs.(11.2 ±3.7) d] of the observation group were significantly less,while the X -ray irradiation time [(17.1 ±3.9) min vs.(10.1 ±3.1) min] was significantly longer.As to VAS incision scores,,postoperative 12h[(4.1 ±1.5) points vs.(8.3 ±2.0) points], postoperative 24h[(2.3 ±1.2)points vs.(7.7 ±2.1)points],postoperative 48h[(1.3 ±0.6)points vs.(5.2 ± 1.6)points]and postoperative 72h[(0.5 ±1.9)points vs.(3.1 ±1.1)points]in the observation group were significantly lower than those in the control group .Compared with the control group ,the ODI scores at 6 months after operation[(11.2 ±3.6)points vs.(17.2 ±4.4)points],12 months after operation[(6.1 ±1.3)points vs.(10.3 ± 2.5)points]and 24 months after operation[(2.9 ±0.8)points vs.(6.4 ±2.1)points]in the observation group were significantly lower,the differences were statistically significant (all P <0.05).Conclusion Minimally invasive treatment of lumbar spinal stenosis with minimally invasive surgery has minimal trauma , less bleeding and shorter hospitalization time.It can significantly improve the symptoms of the incision pain and the functional activities of the limbs,and improve the quality of life of the patients ,and it is worthy of further popularization and application .

Objective To investigate the risk factors of postoperative atrial fibrillation (POAF) in patients with on-pump coronary artery bypass grafting (ONCAB). Methods The clinical data of 200 patients with ONCAB were retrospectively analyzed. The patients were divided into POAF group (n=52) and non POAF group (n=148) according to the occurrence of POAF after operation. The perioperative data including age and gender of all patients were collected and analyzed. The index of opinion of statistical results was classified by two categories Logistic regression analysis, and the related risk factors of POAF were analyzed. The receiver operating characteristic (ROC) curves of the age, red blood cell (RBC), left atrial diameter (LAD) and left ventricular ejection fraction (LVEF) were analyzed in two groups. Results The incidence rate of POAF was 26%, mostly occurred in the postoperative period from 1 d to 3 d. Compared with non POAF group, the age, the proportion of patients with age≥62.5 years or older, the proportion of patients with LAD≥35 mm, left ventricular end-diastolic diameter and perioperative transfusion of RBC were increased in POAF group, and data of mechanical ventilation time, ICU stay time and hospitalization time were prolonged, but the LVEF level decrease ( P<0.05). Among them, the elderly (≥62.5 years), increased LAD (≥35 mm), the higher perioperative transmission amount of RBC were the independent risk factors of POAF after ONCAB, and the higher LVEF was a protective factor for ONCAB. The optimal thresholds for age, RBC, LAD and LVEF were 62.5 years, 1U, 35.5 mm, and 0.34. Conclusion The occurrence of POAF after ONCAB is related with age (≥62.5 years old),LAD≥35 mm and perioperative transfusion of RBC, which can be used as clinically to predict the occurrence of POAF.
