OBJECTIVE: To assess the effectiveness of the single Kocher-Langenbeck approach combined with anterograde channel screw technique for the treatment of acetabular transverse and posterior wall fractures. METHODS: Between March 2020 and October 2022, 17 cases of acetabular transverse and posterior wall fractures were treated with the single Kocher-Langenbeck approach combined with anterograde channel screw technique. There were 11 males and 6 females, with an average age of 53.6 years (range, 42-64 years). Causes of injury included traffic accident in 12 cases, and falling from height in 5 cases. The time from injury to operation ranged from 4 to 16 days with an average of 8.8 days. The operation time, intraoperative blood loss, and fluoroscopy frequency were recorded; X-ray films were reviewed regularly after operation to observe the fracture healing, and postoperative complications were recorded. At last follow-up, Matta score was used to evaluate the reduction of fracture, Harris score and modified Merle D'Aubigné-Postel scores system were used to evaluate the hip joint function. RESULTS: The operation time was 150-230 minutes (mean, 185.9 minutes), the intraoperative blood loss was 385-520 mL (mean, 446.2 mL), and the fluoroscopy frequency was 18-34 times (mean, 27.5 times). Postoperative fat liquefaction occurred in 1 case and the other incisions healed by first intention; 3 cases had limb numbness after operation, and the symptoms disappeared after active symptomatic treatment; no urogenital system and intestinal injury occurred. All patients were followed up 12-28 months (mean, 19.9 months). Bone union was achieved in all cases with an average healing time of 10.8 weeks (range, 8-14 weeks). There was no complication such as loosening and breakage of internal fixators. At last follow-up, according to Matta score, 12 cases achieved anatomic reduction, 3 satisfactory reduction, and 2 fair reduction, the satisfactory rate was 88.2%; according to Harris hip function score, 12 cases were excellent, 3 good, and 2 fair, the excellent and good rate was 88.2%; according to the modified Merle D'Aubign Aubigné-Postel scoring system, the results were excellent in 11 cases, good in 3 cases, and fair in 3 cases, with an excellent and good rate of 82.4%. CONCLUSION The single Kocher-Langenbeck approach combined with anterograde channel screw technique is a minimally invasive method for the treatment of acetabular transverse and posterior wall fractures with less complications, simple operation, and satisfactory effectiveness.

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 summarize the effect of one and a half ventricle repair in the treatment of Ebstein’s Anomaly.Methods:The data of 149 patients diagnosed with Ebstein’s Anomaly and received with surgical treatment in Pediatric Cardiac Surgery Department of Beijing Anzhen Hospital affiliated to Capital Medical University from January 2010 to December 2018 were continuously collected, and the survival rate, reoperation rate and tricuspid regurgitation were followed up in the medium-long term.Results:There were 68 males and 81 females, with a median age of 5.58 years. Patients were divided into Biventricular repair group and one and a half ventricle repair group. The operative age was significantly younger in the one and a half ventricle repair group (4.15 years vs. 6.71 years, P=0.019). There were also significant differences in patiens’ body length[(107.70±31.28)cm vs. (123.20±35.22)cm, P=0.014]and body weight[(19.69±12.22)kg vs. (29.65±20.41)kg, P=0.001], between the two groups, which may be related to the severity of the disease and the need for early surgical intervention. However, there was no significant difference between the two groups in preoperative cyanosis, hemoglobin level, cardiac function, arrhythmia, and common cardiac malformations such as atrial septal defect. Notably, the proportion of preoperatively complicated pulmonary stenosis (10.81% vs. 1.79%, P=0.016) and right ventricular dysplasia (16.22% vs. 3.57%, P=0.008) was significantly higher in the one and a half ventricle repair group. In intraoperative and postoperative indicators, as one and a half ventricle repair under the collateral circulation, extracorporeal circulation time was slightly longer [(125.51±37.35)min vs. (100.44±25.24)min, P<0.001], and other indicators such as aortic cross-clamp time, endotracheal intubation time, length of hospital stay, and mid-term follow-up results, including mid-term mortality, reoperation rate, cardiac function and valvular regurgitation, there was no significant difference between the two groups. However, the proportion of hospital mortality in half ventricular therapy group was slightly higher, which may be related to the poor right heart function and postoperative recovery difficulties. Conclusion:Good follow-up results have been achieved in the treatment of two surgical therapy. Patients with right ventricular dysplasia and pulmonary artery stenosis should be paid more attention to. Pulmonary artery pressure and pulmonary vascular development should be evaluated before surgery to make preparations for one and a half ventricle repair.

Objective::The size and morphology of the right ventricular outflow tract (RVOT) in patients suffering from long-term pulmonary regurgitation (PR) after native RVOT (NRVOT) reconstruction are important factors affecting the feasibility, safety, and effectiveness of transcatheter pulmonary valve replacement. The purpose of this study was to evaluate the feasibility, safety, and effectiveness of a transthoracic Salus valve (Balance Medical Technology Co., Ltd, Beijing, China) in patients with moderate-to-severe PR after NRVOT reconstruction.Methods::Patients with moderate-to-severe PR after NRVOT reconstruction were selected between June 2021 and November 2021 at Beijing Anzhen Hospital. Demographic data as well as preoperative, intraoperative, and follow-up data were reviewed.Results::Ten patients with moderate-to-severe PR after NRVOT reconstruction underwent physical examination, transthoracic echocardiography, and cardiovascular magnetic resonance imaging. Seven patients were selected for transthoracic Salus valve replacement. Six patients underwent implantation of the Salus valve successfully. One valve migrated and was embolized during recovery of the delivery device; the Salus valve was surgically explanted and sutured to the inner wall of the main pulmonary artery. At a mean follow-up of (5.5 ± 1.1) months, dysfunction or migration of the Salus valve embolism was not observed.Conclusions::This early feasibility study demonstrates the feasibility, safety, and effectiveness of transthoracic implantation of a Salus valve in patients with moderate-to-severe PR after NRVOT reconstruction. The short-term effectiveness is clear, medium and long-term effectiveness requires longer follow-up.

【Objective】 To explore the relationship between hidden blood loss （HBL） and risk factors in percutaneous endoscopic interlaminar discectomy （PEID）. 【Methods】 We retrospectively analyzed 113 patients （67 males and 46 females， aged 21-71 years old） with lumbar disc herniation （L5-S1 level） who underwent PEID with complete clinical data in the Department of Spinal Surgery of Subei People’s Hospital Affiliated to Yangzhou University from January 2018 to August 2020. The collected data included general patient indicators （age， body mass index and gender）， underlying diseases （hypertension and diabetes）， laboratory tests （prothrombin time， activated partial thromboplastin time， fibrinogen， hematocrit and hemoglobin level）， imaging related parameters （grade of intervertebral disc degeneration， interlaminar space height and soft tissue thickness of interlaminar approach）， intraoperative significant blood loss and operation time. According to the Gross formula， total blood loss and HBL during operation were calculated. And the risk factors of HBL was analyzed. 【Results】 The total perioperative blood loss was （394.85±130.50） mL， and HBL was （337.09±124.98） mL which accounted for 85.4% of the total blood loss. Multivariate linear regression analysis showed that operation time （P<0.001） and disc degeneration grade （P=0.020） were independent risk factors of HBL. 【Conclusion】 HBL is the main cause of blood loss during PEID， and operation time and disc degeneration grade are independent risk factors that affect the amount of HBL.
