ABSTRACT

Teratoma is a rare tumor, mainly occurring in the ovary, sacrococcygeal region, testis, central nervous system and mediastinum, rarely occurring in the kidney, and adult immature teratoma originating in the kidney is extremely rare. A case of adult left renal immature teratoma was reported in this paper. After radical nephrectomy, pathological examination found that the tumor tissue contains malignant epithelial tissue and a small number of brain tissue. BEP regimen chemotherapy was performed after operation.The patient was followed up for 26 months, and died of organ failure caused by systemic metastasis.

ABSTRACT

Objective@#: Extracranial supra-aortic dissections (ESADs) with severe stenosis, occlusion and/or pseudoaneurysm presents potential risk of stroke. Endovascular stenting to reconstruct non acute phase ESADs (NAP-ESADs) is an alternative to anticoagulant or antiplatelet therapy. However, its feasibility, safety and efficacy of stenting in NAP-ESADs is unclear. This study aims to investigate the long-term outcomes of the feasibility, safety and efficacy of stenting in NAP-ESADs. @*Methods@#: Seventy-four patients with 91 NAP-ESAD vessels with severe stenosis, occlusion and/or pseudoaneurysm presents potential risk of stroke who underwent stent remodeling were enrolled into this respective study from December 2008 to March 2020. Technical success rate, complications, clinical and angiographic results were harvested and analyzed. @*Results@#: Success rate of stent deployment was 99% (90/91) with no procedural mortality or morbidity. Transient ischemic attack occurred in three patients during operation (4.1%, 3/74). Asymptomatic embolisms of distal intracranial vessels were found in two patients (2.7%, 2/74). One hundred and forty-two stents deployed at 85 carotid (135 stents) and six vertebral (seven stents) vessels. Six stent types (Wingspan, 28/135, 20.7%; Solitaire, 10/135, 7.4%; Neuroform, 8/135, 5.9%; LVIS, 2/135, 1.5%; Precise, 75/135, 55.6%; Acculink, 12/135, 8.9%) were deployed at carotid arterial dissection while two types (Wingspan, 5/7, 71.4%; Solitaire 2/7, 28.6%) at vertebral arterial dissection. Digital subtracted angiography (56%, 51/91), computational tomography angiography (41.8%, 38/91) and high resolution magnetic resonance imaging (2.2%, 2/91) were adopted for follow up, with a mean time of 17.2±15.4 months (5–77). All patient modified Rankin Scale scores showed no increase at discharge or follow-up. Angiographically, dissections in 86 vessels in 69 patients (94.5%, 86/91) were completely reconstructed with only minor remnant dissections in four vessels in four patients (4.4%, 4/91). Severe re-stenosis in the stented segment required re-stenting in one patient (1.1%, 1/91). @*Conclusion@#: Stent remodeling technique provides feasible, safe and efficacious treatment of ESADs patients with severe stenosis, occlusion and/or pseudoaneurysm.

ABSTRACT

@#Objective    To investigate the efficacy of uniportal video-assisted thoracoscopic surgery (VATS) anatomic basal segmentectomy. Methods    The clinical data of 15 patients who underwent uniportal VATS anatomic basal segmentectomy between June 2020 and December 2020 were retrospectively reviewed. There were 4 males and 11 females with a median age of 53 (32-70) years. The incisions were placed in the fifth intercostal space across the mid-axillary line. All basal segmentectomies were performed through the interlobar fissure or inferior pulmonary ligament approach following the strategies of single-direction and stem-branch. Results    All patients underwent basal segmentectomy successfully with no conversion to multi-portal procedure or thoracotomy. The median operation time was 120 (90-160) min, median intraoperative blood loss was 20 (10-50) mL, median drainage time was 3 (2-5) d, and median postoperative hospital stay was 4 (4-10) d. The maximum diameter of the lesion in the resected basal segment was 1.2 (0.7-1.9) cm. The median resected lymph nodes were 7 (5-12). There was no evidence of nodal metastases. One patient suffered postoperative atelectasis and subsequent pneumonia. No perioperative death occurred. Conclusion    Uniportal VATS anatomic basal segmentectomy is feasible and safe. It can be performed in a simple manner following the strategy of single-direction.

ABSTRACT

Objective@#: This study aims to investigate the relationship between aneurysm wall enhancement and clinical rupture risks based on the magnetic resonance vessel wall imaging (MR-VWI) quantitative methods. @*Methods@#: One hundred and eight patients with 127 unruptured aneurysms were prospectively enrolled from Feburary 2016 to October 2017. Aneurysms were divided into high risk (≥10) and intermediate-low risk group (<10) according to the PHASES (Population, Hypertension, Age, Size of aneurysm, Earlier SAH history from another aneurysm, Site of aneurysm) scores. Clinical risk factors, aneurysm morphology, and wall enhancement index (WEI) calculated using 3D MR-VWI were analyzed and compared. @*Results@#: In comparison of high-risk and intermediated-low risk groups, univariate analysis showed that neck width (4.5±3.3 mm vs. 3.4±1.7 mm, p=0.002), the presence of wall enhancement (100.0% vs. 62.9%, p<0.001), and WEI (1.6±0.6 vs. 0.8±0.8, p<0.001) were significantly associated with high rupture risk. Multivariate regression analysis revealed that WEI was the most important factor in predicting high rupture risk (odds ratio, 2.6; 95% confidence interval, 1.4–4.9; p=0.002). The receiver operating characteristic (ROC) curve analysis can efficiently differentiate higher risk aneurysms (area under the curve, 0.780; p<0.001) which have a reliable WEI cutoff value (1.04; sensitivity, 0.833; specificity, 0.67) predictive of high rupture risk. @*Conclusion@#: Aneurysms with higher rupture risk based on PHASES score demonstrate increased neck width, wall enhancement, and the enhancement intensity. Higher WEI in unruptured aneurysms has a predictive value for increased rupture risk.

ABSTRACT

@#Objective    To analyze the operation outcomes and learning curve of uniportal video-assisted thoracoscopic surgery (VATS). Methods    All consecutive patients who underwent uniportal VATS between November 2018 and December 2020 in Shangjin Branch of West China Hospital of Sichuan University were retrospectively enrolled, including 62 males and 86 females with a mean age of 50.1±13.4 years. Operations included lobectomy, segmentectomy, wedge resection, mediastinal mass resection and hemopneumothorax. Accordingly, patients' clinical features in different phases were collected and compared to determine the outcome difference and learning curve for uniportal VATS. Results    Median postoperative hospital stay was 5 days, and the overall complication rate was 8.1% (12/148). There was no 30-day death after surgery or readmissions. Median postoperative pain score was 3. Over time, the operation time, incision length and blood loss were optimized in the uniportal VATS lobectomy, the incision length and blood loss increased in the uniportal VATS segmentectomy, and the postoperative hospital stay decreased in the uniportal VATS wedge resection. Conclusion    Uniportal VATS is safe and feasible for both standard and complex pulmonary resections. While, no remarkable learning curve for uniportal VATS lobectomy is observed for experienced surgeon.

ABSTRACT

Objective:To analyze the therapeutic effect of ankle arthrodesis with reverse proximal humerus internal locking system plating plus cannulated screwing via the transfibular approach in the treatment of end-stage ankle arthrosis.Methods:From April 2014 to January 2018, 19 patients (19 ankles) with end-stage ankle osteoarthritis were treated at Department of Foot and Ankle Surgery, Zhengzhou Orthopaedics Hospital by ankle arthrodesis with reverse PHILOS plating plus cannulated screwing via the transfibular approach for multi-plane fixation. They were 9 men and 10 women, aged from 36 to 65 years (average, 46.7 years). The disorder was further diagnosed as traumatic arthritis in 9 cases, as osteoarthritis in 6, as talar necrosis in 2 and as equinovarus in 2, and affected the left ankle in 11 cases and the right in 8. All cases belonged to stage Ⅲ osteoarthritis according to the Morrey-Wiedeman imaging classification. Their American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS), joint fusion and complications were observed preoperatively and at the last follow-up.Results:All the 19 patients were followed up for 18 to 62 months (average, 31.5 months). Their AOFAS scores were improved from preoperative 46.3±2.1 to 81.6±0.9 at the last follow-up, and their VAS was reduced from preoperative 7.1±0.2 to 2.0±0.2 at the last follow-up, showing significant differences ( P<0.001). All their ankle joints obtained bony fusion after 9 to 14 weeks (mean, 11.5 weeks). No implant loosening or breakage was observed. All the patients were satisfied with their operative results at the last follow-up. Dorsal lateral foot numbness was observed in one patient who became asymptomatic after neurotrophic medication for 3 months. Lateral distal wound dehiscence happened during removal of stitches at 2 weeks after operation in another patient but healed after debridement. The last follow-up found subtalar joint degeneration in 2 cases and talonavicular joint degeneration in one but no clinical symptoms in the 3. Conclusion:Ankle arthrodesis with reverse PHILOS plating plus cannulated screwing via the transfibular approach is a fine treatment for end-stage ankle arthrosis, because it leads to reliable fixation, short fusion time, alleviated pain and improved ankle function.

ABSTRACT

Space-occupying brain edema is a life-threatening complication in patients with cerebellar infarction, which occurs in 17-54% of the patients. The level of consciousness should be monitored closely and the changes of CT/MRI should be followed up for cerebellar infarction patients with a higher risk of deterioration. Ventriculostomy/extraventricular drainage and suboccipital decompressive craniectomy should be performed in space-occupying cerebellar infarction patients with clinical deterioration.

ABSTRACT

Numerical simulation of stent deployment is very important to the surgical planning and risk assess of the interventional treatment for the cardio-cerebrovascular diseases. Our group developed a framework to deploy the braided stent and the stent graft virtually by finite element simulation. By using the framework, the whole process of the deployment of the flow diverter to treat a cerebral aneurysm was simulated, and the deformation of the parent artery and the distributions of the stress in the parent artery wall were investigated. The results provided some information to improve the intervention of cerebral aneurysm and optimize the design of the flow diverter. Furthermore, the whole process of the deployment of the stent graft to treat an aortic dissection was simulated, and the distributions of the stress in the aortic wall were investigated when the different oversize ratio of the stent graft was selected. The simulation results proved that the maximum stress located at the position where the bare metal ring touched the artery wall. The results also can be applied to improve the intervention of the aortic dissection and the design of the stent graft.

ABSTRACT

Congenital heart disease (CHD) is the most common congenital malformation and also one of the common causes of heart failure in children.At present,the clinical diagnosis of heart failure in children mainly depends on the medical history,symptoms and signs,with strong subjectivity and lack of timely and simple objective criteria,which are easy to be missed.Brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-ProBNP) are polypeptides synthesized and secreted by ventricular myocytes,which have good sensitivity to reflect ventricular systolic,diastolic function and pre-and post-load.They have been widely used in various cardiovascular diseases.In recent years,many studies have shown that the plasma concentration of the two can be used to guide perioperative surgical treatment and evaluate the perioperative prognosis risk of children with CHD.This article reviews the application of BNP and NT-ProBNP in children with CHD with heart failure,especially during perioperative period.
