ABSTRACT
Objective:To investigate the method and effect of microneurosurgery in the treatment of recurrent craniopharyngioma.Methods:The clinical data of 41 recurrent craniopharyngioma patients treated by microneurosurgery in Capital Medical University Sanbo Brain Hospitalfrom January 2018 to January 2022 were retrospectively analyzed.Results:Among the 41 patients, 38 cases were treated with the frontal basal interhemispheric approach and 3 cases with the translongitudinal fissure combined with the transSylvian fissure approach. Gross total resection was performed in 34 cases (82.9%) and subtotal resection in 7 cases (17.1%). One patient (2.4%) died of pulmonary embolism during perioperative period. All patients had transient electrolyte disorder after operation, and recovered within 3 months after treatment. All patients had endocrine dysfunction. After 3 months of hormone replacement therapy, 11 patients were cured. Visual acuity decreased in 3 cases after operation, and 2 cases improved after treatment.Conclusions:Surgical treatment of recurrent craniopharyngioma is very difficult, which is a great challenge for doctors and patients. However, through the individualized evaluation of the patients and the meticulous technique of the doctors during the operation, a satisfactory effect can be achieved post the operation of recurrent craniopharyngioma.
ABSTRACT
Objective:To explore the etiology and treatment of craniopharyngioma with aneurysm.Methods:Seven cases of craniopharyngioma with aneurysm from March 2014 to October 2019 treated in Sanbo Brain Hospital, Capital Medical University were retrospectively analyzed. Among the 7 patients, there were 5 males and 2 females. There were 4 cases of recurrent craniopharyngiomas, 1 case of primary tumor and 2 cases of non-recurrence tumor. Three patients with blood blister-like aneurysms were treated with microsurgical suture after craniopharyngioma resection. Among the three cases with internal carotid artery fusiform aneurysm, 1 case underwent craniopharyngioma resection after internal maxillary artery-radial artery-middle cerebral artery bypass and isolation of the aneurysm; 1 case only underwent internal maxillary artery-radial artery-middle cerebral artery bypass and isolation of the aneurysm for non-recurrence tumor; 1 case underwent craniopharyngioma resection and dynamic observation of aneurysm. One case with a cystic aneurysm of the middle cerebral artery was clipped and the craniopharyngioma did not relapse.Results:All patients had no serious postoperative complications. During the follow-up period, there was no recurrence of craniopharyngioma, no recurrence of treated aneurysms, and the stability of aneurysms was observed.Conclusions:Inflammatory stimulation of craniopharyngioma cystic fluid and operation itself are the important reasons for the occurrence of aneurysms after craniopharyngioma surgery. Choosing appropriate surgical methods can complete the removal of craniopharyngioma and the treatment of aneurysms at one time.
ABSTRACT
Objective:To retrospectively summarize the imaging and clinical features of craniopharyngioma in order to improve the preoperative diagnosis level.Methods:One hundred and twenty-seven patients with craniopharyngioma diagnosed by pathology in Sanbo Brain Hospital, Capital Medical University from March 2019 to June 2021 were selected and the pathological coincidence rate of imaging diagnosis were analyzed.Results:The coincidence rate of MRI diagnosis was 89.3%. The coincidence rate of CT diagnosis was 71.5%. On T 2WI and T 1WI enhanced sequences, the solid portion of the tumor may showed uneven hyperintensity, diffuse striation and spotty hyperintensity. MRI sagittal view was helpful in showing small tumors, but less sensitive to calcification than CT. MRI enhancement was very important, especially for patients with solid lesions. Conclusions:The imaging findings of craniopharyngioma are diverse. Some characteristic manifestations provide important information for the diagnosis and differential diagnosis of craniopharyngioma, which can improve the diagnostic accuracy combined with clinical data.
ABSTRACT
Objective:To evaluate the clinical effect of anterior clinoid process grinding in the treatment of ophthalmic / superior clinoid process aneurysms and sellar tumors.Methods:The clinical data of 16 patients who underwent anterior clinoid process grinding in Sanbo Brain Hospital, Capital Medical University from January 2015 to July 2021 were analyzed retrospectively. There were 1 patient with recurrent craniopharyngioma, 1 patient with recurrent pituitary adenoma, 13 patients with aneurysms, and 1 patient with suprasellar granulosa cell tumor combined with ophthalmic aneurysm of right internal carotid artery. The Modified Rankin Scale (mRS) score was used to evaluate the situation at discharge and in the medium-and-long term.Results:Sixteen patients underwent anterior clinoidprocess grinding. At discharge and the latest follow-up, the mRS scores of the patients were 0-2. A total of 15 aneurysms were treated, and there were no symptoms of visual loss or visual field defect after operation. No cerebrospinal fluid leakage occurred in all patients.Conclusions:The grinding of anterior clinoid process can effectively and fully stretch the optic nerve and internal carotid artery, and can observe the tumor neck at the lower end of pituitary stalk and the ocular segment/superior clinoid process of internal carotid artery under direct vision. It is one of the important auxiliary methods for the treatment of sellar lesions.
ABSTRACT
Objective:To investigate the effect of ultrasound measurement of optic nerve sheath diameter (ONSD) in adult patients with elevated intracranial pressure (ICP).Method:From June 2017 to March 2020, A total of 64 patients (32 patients with elevated ICP and 32 patients with normal ICP) were placed with invasive intracranial pressure monitoring probe in Beijing Pinggu Hospital. Their ICP and ONSD were continuously monitored. Thirty-two healthy volunteers were recruited as control group to check ONSD. The correlation between ONSD and ICP, and the changes of ICP and ONSD after osmotic therapy were observed.Results:The ONSD in ICP increased group was significantly higher than that in normal ICP group: (5.77 ± 0.3) mm vs. (5.01 ± 0.1) mm, with statistical difference ( P<0.05), and there was a positive correlation between ONSD and ICP. There was no significant difference in ONSD between normal ICP group and control group ( P>0.05). Conclusions:Ultrasound monitoring ONSD can reflect the level of ICP and evaluate the effect of osmotic therapy and the prognosis of patients. Bedside ultrasound examination of optic nerve sheath diameter could be used to judge ICP and to evaluate the curative effect of osmotic therapy, with high clinical application value.
ABSTRACT
Objective:To explore the value of tidal lung function in distinguishing central and small intrathoracic airway obstructive lesions.Methods:A total of 124 infants with intrathoracic obstructive diseases, including bronchiolitis obliterans (BO), bronchiolitis, airway foreign body, and airway stenosis, were confirmed in Children′s Hospital of Chongqing Medical University from April 2014 to June 2019 and selected as subjects, and 111 normal infants were enrolled as healthy control group.According to the location of lesions, these subjects suffering from intrathoracic obstructive diseases were divided into small airway lesion group(BO, bronchiolitis) and central airway lesion group(airway foreign body, airway stenosis). Lung function was assessed by plethysmography.Results:As for the ratio of time to reach peak tidal expiratory flow to total expiratory time (TPTEF/TE) and the ratio of volume to reach peak tidal expiratory flow to total expiratory volume (VPTEF/VE), all disease groups were lower than that in healthy control group TEF/TE: BO 13.2(10.3, 16.3)%, bronchiolitis 15.9 (13.2, 19.7)%, airway foreign body 24.5 (16.7, 30.7)%, airway stenosis 20.7 (16.1, 29.3)%, healthy control group 30.2(25.6, 36.5)%; VPTEF/VE: BO 18.2(17.8, 22.3)%, bronchiolitis 20.3(17.0, 21.6)%, airway foreign body 26.0(20.5, 30.7)%, airway stenosis 22.9(20.2, 29.1)%, healthy control group 31.5(28.1, 37.0)%]( P<0.05) and the lesion in the small airway lesion group was significantly lower than that in central airway lesion group.Compared with the healthy control group, the functional residual capacity (FRC)was higher in each disease group[BO (501.6±166.5) mL, bronchiolitis (334.6±149.6) mL, airway foreign body (392.2±130.1) mL, airway stenosis (350.1±127.9) mL, healthy control group (191.6±73.8) mL]( P<0.05). The ratio of peak expiratory flow to tidal expiratory flow at 25% remaining expiration(PF/TEF 25) was obviously higher in small airway lesion group than that in central airway lesion and healthy control group [BO 232.7(183.2, 261.2)%, bronchiolitis 186.4 (153.3, 247.7)%, airway foreign body 143.1(126.8, 168.9)%, airway stenosis 140.3(122.9, 186.0)%, healthy control group 132.3 (123.1, 147.8)%] ( P<0.05), while no significant differences were found between central airway lesion group and healthy control group ( P>0.05). There were no significant differences in effective airway resistance among all groups ( P>0.05). The tidal breathing flow volume (TBFV) curve shape of small airway lesion group showed the depression of expiratory phase to the transverse axis, while the slope of descending branch of expiratory phase had no significant increase in central airway lesion group. Conclusions:Combined with the increase in PF/TEF 25, the decrease in TPTEF/TE and VPTEF/VE is the characteristic of small airway obstruction.PF/TEF 25 is a sensitive index reflecting small airway obstruction.Combined with the value of lung function parameters, the shape of TBFV is helpful to distinguish central and small airway obstructive lesions.
ABSTRACT
OBJECTIVE@#To explore the value of leukotriene D4 (LTD4) bronchial provocation test (BPT) in detection of airway hyper-responsiveness (AHR) in children.@*METHODS@#A total of 151 children aged 6 to 14 years, including 86 in remission of asthma and 65 with acute bronchitis, who were followed up in our respiratory clinic between November, 2017 and August, 2018. The children were randomly divided into LTD4 group (78 cases) and methacholine (MCH) group (73 cases). In LTD4 group, the 78 children underwent LTD4-BPT, including 46 with asthma and 32 children having re-examination for previous episodes of acute bronchitis; in MCH group, the 73 children underwent MCH-BPT, including 40 with asthma and 33 with acute bronchitis. MCH-BPT was also performed in the asthmatic children in the LTD4 group who had negative responses to LTD4 after an elution period. The major adverse reactions of the children to the two BPT were recorded. The diagnostic values of the two BPT were evaluated using receiver-operating characteristic (ROC) curve.@*RESULTS@#There was no significant difference in the results of basic lung function tests between LTD4 group and MCH group (>0.05). The positive rate of BPT in asthmatic children in the LTD4 group was significantly lower than that in the MCH group (26.1% 72.5%; < 0.05). The positive rate of BPT in children with previous acute bronchitis in the LTD4 group was lower than that in the MCH group (3.1% 15.2%). The positive rate of MCH-BPT in asthmatic children had negative BPT results in LTD4 group was 58.8%, and their asthma was mostly mild. The sensitivity was lower in LTD4 group than in MCH group (0.2609 0.725), but the specificity was slightly higher in LTD4 group (0.9688 vs 0.8485).The area under ROC curvein LTD4 group was lower than that in MCH group (0.635 0.787). In children with asthma in the LTD4 group, the main adverse reactions in BPT included cough (34.8%), shortness of breath (19.6%), chest tightness (15.2%), and wheezing (10.9%). The incidence of these adverse reactions was significantly lower in LTD4 group than in MCH group ( < 0.05). Serious adverse reactions occurred in neither of the two groups.@*CONCLUSIONS@#LTD4-BPT had high safety in clinical application of children and was similar to the specificity of MCH-BPT. However, it had low sensitivity, low diagnostic value, and limited application value in children's AHR detection.

Objective:To explore the value of airway responsiveness measurement by the tidal lung function test combined with the bronchial provocation test (BPT) in the diagnosis of infant cough variant asthma (CVA), and to provide evidence for clinical diagnosis of CVA.Methods:The tidal lung function test and BPT test results of 131 cases of chronic cough (including 70 CVA cases and 61 non-CVA cases) treated in the Asthma Specialist Clinic of Children′s Hospital Affiliated to Chongqing Medical University from January 2018 to September 2018 were retrospectively analyzed.The results between CVA group and non-CVA group were compared.Results:There was no significant difference in the basal tidal lung function detection results between the CVA group and non-CVA group ( P>0.05). The positive rate of BPT in the CVA group was significantly higher than that in the non-CVA group (98.6% vs. 27.9%, χ2=30.757, P<0.01). Among the patients with positive BPT, the proportion of patients with moderate and severe positive reactions in the CVA group was significantly higher than that in the non-CVA group (40.0% vs. 3.3%, 15.7% vs. 0, χ2=24.894, 20.464, all P<0.01). During BPT test process, a significantly greater number of patients showed wheezing and a significant decrease in oxygen saturation(SpO 2) in the CVA group than in the non-CVA group (50.0% vs.0, 91.4% vs.45.9%, χ2=32.169, 36.544, all P<0.01), while the number of patients with severe cough and shortness of breath was similar in both groups (all P>0.05). After the application of bronchodilator or oxygen inhalation, the symptoms of polypnea and wheezing disappeared in all children.The values of the ratio of the time to reach peak tidal expiratory flow to total expiratory time[(TPTEF/TE)%] and the ratio of the volume required to reach peak tidal expiratory flow to total expiratory volume[(VPTEF/VE)%] recovered to more than 80% of the basic values and SpO 2 up to 95%. Conclusions:The tidal lung function test combined with the BPT test is of certain significance for the diagnosis and differential diagnosis of CVA infants.CVA can be better diagnosed based on the degree of BPT and the clinical manifestations during the course of the test.
ABSTRACT
Objective To explore the surgical treatment of spindle aneurysms in V4 segment of vertebral artery. Methods The clinical data, surgical methods and prognosis of 6 patients with V4 spindle aneurysms of vertebral artery admitted from 2011 to November 2018 in Sanbo Brain Hospital were retrospectively analyzed,Results There were 4 males and 2 females aged from 45 to 65 years. Aneurysm rupture and bleeding occurred in 3 cases. Far lateral approach was used in all patients. One case was clipped with window aneurysms, 2 cases were treated with occipital artery (OA)- posterior inferior cerebellar artery (PICA) bypass, and 3 cases were treated with vertebral artery occlusion. Postoperative patients were generally in good condition. Postoperative CT arteriography confirmed that the bypass vessels were unobstructed in 2 cases. All vertebral aneurysms were treated satisfactorily and PICA arteries were preserved. Tracheotomy was performed in 5 patients (1 case was incised before operation). Three patients were removed 3 months after operation. The Glasgow Prognosis Score (GOS) was 4 points. Long-term tracheotomy was performed in 1 case, and GOS score was 3 points. Two patients died 4 months and 3 years after operation. Conclusions Craniotomy is an important method for the treatment of spindle aneurysm of V4 segment of vertebral artery. Different surgical methods should be selected according to the size of the aneurysm, the relationship between the location of the aneurysm and PICA, and the compensation of the vertebral artery.
ABSTRACT
Objective To analyze the features of supraclinoid internal carotid aneurysms. The experience and mistakes in the microsurgery of supraclinoid internal carotid aneurysms were summarized to improve the results. Methods The data of 24 cases of supraclinoid internal carotid aneurysms that were operated from May 2004 to March 2009 were reviewed. There were 6 cases of small or middle aneurysms, 18 cases of large or giant aneurysms. The operative methods included direct clipping, partial excision of aneurysm with reconstruction of the parent artery, aneurysm trapping with extracerebral/intracerebral (EC-IC) bypass, etc. Results Among the 24 cases, 8 cases had good results. Ten cases occurred hemiplegja post operation immediately, with 5 cases recovered to grade IV ,3 cases had aphasia,5 cases with vision acuity fall,4 cases had abnormal eyeball movement,2 cases had continued coma and died finally. Second operations were performed in 3 cases. The total operation rate of well results was 66.7% (16/24). Mortality rate was 8.3% (2/24). Conclusions The operative technique of the supraclinoid internal carotid aneurysms is difficult because of the location and the large size of the aneurysms. The temporary obstruction' of the parent artery is often needed, so the aneurysm can be partially resected and clipped. The results of clipping of large or giant aneurysms are better than the other methods. But in large or giant aneurysms that had thrombus, the EC-IC bypass is needed to prevent large infarction. The bypass procedure may induce some severe complications that result in some poor outcome.
