ObjectiveTo investigate the diagnostic value of transbronchoscopic lung biopsy (TBLB) without X-ray fluoroscopy in patients with peripheral pulmonary lesions.Methods Fifty patients with peripheral and diffuse pulmonary lesions and without cavity lesions from January to December 2011 were selected and examined by conventional hronchoscopy.According to the anatomical orientation of CT image and bronchial tree path,TBLB was performed by electronic bronchoscope.ResultsThere were 63 cases of TBLB in 50 patients and 30 patients got confirmed diagnosis (60.0％),including 24 cases in 35patients with peripheral pulmonary lesions (68.6％),and 6 cases in 15 patients with diffuse pulmonary lesions (40.0％).There was no severe complication during and after electronic bronchoscopy.ConclusionsTBLB without X-ray fluoroscopy is a convenient,safe and repeatable operational method with fewer complications.It has higher clinic diagnostic value in pulmonary diseases.

Objective To study the effect of chest drainage and injection of pleural adhesion agent in the treatment of the malignant pleural effusion (MPE),and to discuss the influences about it.Methods The data of the in-hospital patients with MPE who received thoracostomic drainage and pleural adhesions were retrospectively analyzed.11 factors were selected as research subjects,such as sex,age,KPS score,tissue origin of primary tumor,the position of hydrothorax,the cell number,the level of protein,the level of LDH in the effusion,species of sclerosant,the fluid volume of hydrothorax in 24 hours before using sclerosant,the duration between pleurodesis and removing the tude.Then,the factors that affected the effect of pleurodesis were analyzed.Results In total 196 cases,61 patients acquired significant efficacy,71 men achieved good result,and 64 people had no effect.The total effective rate was 67.3％.Univariate analysis showed that KPS score,tissue origin of primary tumor,the position of hydrothorax,the level of protein and LDH in the effusion,species of sclerosant,the fluid volumeof hydrothorax in 24 hours before using sclerosant were related to the effect.Multivariate Logistic regression analysis indicated that KPS score,tissue origin of primary tumor,the position of hydrothorax,the level of protein and LDH in the effusion,species of sclerosant,the fluid volume of hydrothorax in 24 hours before using sclerosant were indepent factors for efficacy of the pleurodesis.Conclusion It seems that good adhesion effect achieved in patients with MPE that KPS score ≥70,primary breast carcinoma,using sapylin as a sclerosant,the fluid volume of hydrothorax ≤ 200nmL in 24 hours before using sclerosant.

Objective:To explore the effect of gradual dural decompression(GDD)in preventing intraoperative encephalocele in severe traumatic brain injury (TBI).Methods:A retrospective case-control study was conducted to analyze the clinical data of 78 patients with severe TBI admitted to Affiliated Hospital of North Sichuan Medical College from January 2015 to October 2018, including 55 males and 23 females, aged 15-68 years with an average age of 38.2 years. Thirty-eight patients were treated by GDD (GDD group). During the operation, the hematoma was cleared by opening a window in the area with more hematoma, then gradually cleared in the area without opening a window. Finally, the dural "junction" was cut and the skull was closed quickly after covering the dural patch. The other 40 patients were operated by fast open dural (FOD) operation (FOD group). The incidence of intraoperative encephalocele, intracranial pressure data at the time, 24 hours, 72 hours and 7 days after operation, incidence of delayed intracranial hematoma and glasgow outcome score (GOS) at 3 months after operation were compared between the two groups.Results:All patients (except for 26 deaths) were followed up for 3-14 months, with an average of 8 months. None had intraoperative encephalocele in GDD group, compared to 8 patients in FOD group ( P<0.05). Intracranial pressure in GDD group was respective (18.4±3.6)mmHg, (20.4±4.0)mmHg, (27.7±4.6)mmHg and (28.3±4.5)mmHg at the time, 24 hours, 72 hours and 7 days after operation, showing no significant differences compared to FOD group [(19.1±3.4)mmHg, (20.9±3.9)mmHg, (27.0±3.5)mmHg, (27.6±3.4)mmHg, respectively] ( P>0.05). There was no significant difference in the incidence of delayed intracranial hematoma between the two groups [16% (6/38) in GDD group and 16% (5/32) in FOD group (except 8 cases of intraoperative encephalocele)] ( P>0.05). Three months after operation, the good rate of GOS score of GDD group was 61% (23/28) higher than that of FOD group [28% (11/40)], and the mortality rate of GDD group was 21% (8/38) lower than that of FOD group [45% (18/40)] ( P<0.05). There was no significant difference between the two groups in medium severe disability and plant survival rate ( P>0.05). Conclusions:For patients with severe TBI, compared with FOD, GDD is more effective in reducing the incidence of intraoperative encephalocele, improving the prognosis and decreasing mortality.

Objective To explore the clinical features,diagnoses,differential diagnoses and treatments of superior cerebellar artery aneurysms.Methods The clinical data of 16 patients with superior cerebellar artery aneurysms,admitted to our hospital from January 2013 to March 2018,were retrospectively collected.Their clinical manifestations,imaging features,surgical effects and related problems in the process of diagnoses and treatments were analyzed.Results Among the 16 patients,11 were caused by aneurysm rupture;8 had subarachnoid hemorrhage alone,and three had subarachnoid hemorrhage accompanied by ventricular hemorrhage;CT and CTA confirmed that 8 were superior cerebellar artery aneurysms,two were posterior cerebral artery aneurysms,and one was with unclear diagnosis.In the other 5 patients,three had eyelid ptosis and two had abducent nerve palsy;CT,CTA or MR imaging showed that two were considered as ventral brainstem occupying lesions,and three did not have clear diagnosis.Finally,all patients were diagnosed as having superior cerebellar artery aneurysms by three-dimensional DSA.Five patients were treated with interventional embolization first,and one was treated with surgical clipping because of vertebral artery stenosis and difficulty of catheter access;two patients were transferred to our department for surgical clipping due to aneurysm rupture after embolization treatment in other hospitals;and 9 patients were treated by surgical clipping directly.After treatments,one patient was in bed for a long time due to cerebellar infarction and systemic complications,and the other 15 patients recovered well;two of them underwent ventricular peritoneal shunt due to hydrocephalus.Conclusions Superior cerebellar artery aneurysm has onset of subarachnoid hemorrhage mostly,and oculomotor and abductor nerve paralysis,and space occupying manifestation around the brainstem sometimes.For patients with suspicious posterior circulation aneurysms whose diagnosis or location are unclear,three-dimensional DSA examination should be performed early to confirm the diagnosis.Treatment should be taken as soon as possible once the superior cerebellar artery aneurysm is defined.Interventional embolization may be the first choice,but it is necessary to master the methods of surgical clipping in order to treat the disease timely.
