Objective To investigate the endovascular treatment of peripheral vascular anomaly in children and its efficacy.Methods Eighty-three children with peripheral vascular anomaly were treated via endovascular means. Before and during the endovascular operation,all the cases were diagnosed as follows: arteriovenous fistula in 23 cases, cirsoid angioma 32 and cavernous hemangioma 28. The endovascular approaches included:①transcatheter embolization using coils or gelfoam sponge;② transcatheter embolization combined with local cirrhosis agents treatment.Results Immediate angiography after embolization showed all the arteriovenous fistulas and hemangiomas were efficiently occluded and the clinical presentation and symptoms improved greatly. Follow-up one to three years after operation demonstrated 100% of efficacy and 68.7% curative rate with no complications. Conclusions Endovascular approach for peripheral vascular anomaly in children is a micro-invasive, safe and effective way.

Objective To explore the clinical meanings of serum CA19-9 levd in hepatocirrhosis patients. Methods 61 hepatitis B and hepatocirrhosis patients were as treatment group, and 35 normal were as control group. The content of serum CA19-9 was measured by dectrochemistry lighting and the liver function was determined too. According to Child-Pugh liver function integral method,the treatment group was divided into 27 cases of A grade,20 cases of B grade and 14 cases of C grade. Results The serum CA19-9 level in hepatocirrhosis patients was higher than that of normal group significantly(P< 0. 005 ). The serum CA19-9 level decreaed obviously through the treat- ment,thereinto A and B grade fell evidendy in the Child-Pugh liver function integral method( P < 0. 005). C grade was not significantly different(P<0.05 ). The serum CA19-9 levd was positivdy associated with TBiL, ALT and AST of liver function integral method. Conclusion The serum CA19-9 levd of hepatocirrhosis patients is improved in different degrees. And it can be a prognostic target and used to estimate the degree of damage of liver function of hepatocirrhosis patients.

Objective To detect the change of discharge phase of guinea pig hippocampal CA1 pyramidal cells during visual discriminative task with an effective and convenient program we designed. Methods Five guinea pigs were performed by extracellular single unit recording in vivo when they were performing visual discriminative task. Discharge signals of individual pyramidal cells were extracted from different frequency signals by wavelet transform (WT), which made it feasible to calculate discharge phase of pyramidal cells in terms of time correlation between discharge and ? rhythm. Results The discharge phase of CA1 pyramidal cells in the 1 to 5s interval before visual discriminative task (172??1.8?) was obviously earlier than that in the 6 to 10s interval after visual discriminative task (189??3.7?) ( P0.01). Conclusion The program we designed is capable of detecting discharge phase of pyramidal cells. Regular shift of discharge phase of hippocampal CA1 pyramidal cells emerges before and after performing visual discriminative task.

Objective To explore risk factors,prevention and treatment of common complications of benign esophageal stenosis treated with the retrievable covered stents in children.Methods Fifteen cases,diagnosed as benign esophageal stenosis by barium esophagogram were treated with retrievable covered stents under fluoroscopy,Then the stents were removed after 2-3 weeks.The cases were followed-up and complications were observed.Results The stents were successful implanted in all cases.The diet was improved obviously after operation,and gradually transformed from liquid,semiliquid to normal feeding.At the same time,narrow section gradually expanded from 0.1-0.6 cm to 0.6-1.5 cm.Postoperative follow-up was in 1,2,3 weeks and 3 months.Main complications were stents shift in 5 cases,esophageal restenosis in 2 cases,esophageal-tracheal fistula in 1 case,postoperative dull pain behind sternum and foreign body sensation in 6 cases.Relevant preventions and treatments were performed based on different complications.Conclusion It should not be ignored that complications after covered stent placement are more in children than in adults,preventions and treatments should be taken positively.

Objective To explore the interventional treatment method for complex and refractory lymphatic malformation in children.Methods The clinical data of 78 cases with complex and refractory lymphatic malformation during January 2013 to January 2016 in our department were retrospectively analyzed.The lesions involved the neck in 28 cases,maxillofacial regions in 19 cases,the chest and armpit in 8 cases,the limb in 7 cases,the pelvic cavity and retroperitoneal space in 6 cases,the superior mediastinum in 3 cases,the hypogloeeis in 3 cases and scrotum or perineum region in 4 cases.All the children underwent ultrasound or MRI imaging studies preoperatively.The interventional procedures included:(1) Percutaneous puncture of the LM for sclerotherapy.The lesions were punctured with 20 G needle under the guidance of DSA or ultrasound and the correct positions were confirmed with angiography.The liquid of the lesions was extracted as far as possible.The dosage of sclerosing agents was adjusted according to the size of lesion.The dose of Laurolacrogol injection was 1/10—1/5 of the amount of the liquid in the lesions and the maximum of Laurolacrogol foam was ≤8 ml(20 mg).The dose of Pingyangmycin was ≤ 8 mg.(2) The drainage catheter placement and sclerotherapy.Percutaneous catheter drainage under ultrasound guidance or by surgery was conducted.The liquid in the lesions was drained by retaining the catheter for 1-4 weeks,and sclerotherapy was applied for several sessions during this period.(3) Treatment for one time a week,2 times a session.The interval of every two sessions was 4 weeks.The sclerosing agents included:Laurolacrogol Injection or Pingyangmycin for the lesions with high tension,Laurolacrogol foam for the lesions with low tension,Pingyangmycin for the microcystic lesions.Statistical analysis was conducted using SPSS20.0 software.Results A total of 208 sessions of sclerotherapy for 78 LM patients were performed and average session was (3.0±0.8).Nine patients used Lauromacrogol foam,23 patients used Lauromacrogol Injection,39 patients used pingyangmycin,while combined treatment was conducted in 7 patients.Laurolacrogol injection was used in 20 cases,Pingyangmycin in 29 cases and combination therapy in 5 cases for the high tension lesions in the neck,maxillofacial,chest and armpit.The low tension lesions of pelvic cavity and retroperitoneal space in 6 cases and of superior mediastinum in 3 cases were placed with draining catheters,and treated with sclerotherapy with Laurolacrogol foam.Three cases with hypogloeeis LM was neonates,who were treated with Laurolacrogol injection.The lesions on the limb and scrotum or perineum region were almost microcystic,were treated with Pingyangmycin in 9 cases and with combination therapy in 2 cases.The total curative rate was 97.4％ (76/78),total effective rate was 100％ (78/78).Imaging examinations showed that the cavities were closed or only a small amount of residual sclerotic lesions were present.Clinical examinations showed that the surface masses almost disappeared.The follow up period was 6 months to 2 years.There were no serious complication and adverse reactions occurred.Conclusions Interventional treatment is a safe,effective,and minimally invasive treatment for the complex and refractory lymphatic malformation.In order to receive the best treatment effect,we should use targeted therapy for different region and type of LM.
