ABSTRACT

Objective:To evaluate the efficacy of endovascular stenting of various types of venous sinus stenosis in idiopathic intracranial hypertension (IIH).Method:Clinical, radiological, and manometric data before and after stenting in venous sinus stenosis were retrospectively analyzed in 99 IIH patients who were refractory to medical therapy or rapidly progressed between July 2004 to July 2019. The follow-up period was between 2.3 months to 11 years.Results:Our study enrolled 21 men (21.2%)and 78 women (78.8%) with average body mass index (BMI) 19.2-40.6(27.0±4.4) kg/m2 and median age 37 years. Before stent placement, the mean transverse sinus stenosis gradient was 1-59(26±8) mmHg. Patients with extrinsic stenosis were younger than those with intrinsic and mixed stenosis. In all cases, stenting was effective for papilledema. Fifty patients complained of headaches. Pulsatile tinnitus in twenty-eight patients completely alleviated after stenting. In one patient, replacement of stent did not improve symptoms, and a subsequent CSF diversion procedure was performed and effective.Conclusion:Irrespective of the type of stenosis, stenting of venous sinus stenosis is an effective treatment for IIH. Patients with persistent papilledema post-stenting and elevated transverse pressure pre-stenting should be followed closely as high risk of stenting failure may occur and further diversion procedure is needed.

ABSTRACT

A 4-year-old boy complained of weakness of the lower limbs for one and a half month.The child had been diagnosed as X-linked agammaglobulinemia (XLA) at 1-year old.In recent one and a half month,he gradually suffered from activity intolerance and fatigue,inability to jump and run,staggering gait and slow speech.All the symptoms above indicated deteriorating motor function.The brain magnetic resonance imaging revealed abnormal signals in white matter and brain atrophy.The cerebrospinal fluid analysis detected the presence of oligoclonal immunoglobulin G band.In short term after intravenous immunoglobulin and methylprednisolone treatment,the boy's lower extremity function and speech speed were slightly improved.However,at 1-year follow-up,the boy's condition became even worse.The child could not sit without support and had difficulty in swallowing.The child could not speak or follow any commands.Neurological examination revealed spastic quadriplegia and pseudobulbar palsy.Progressive neurodegeneration is not a common syndrome in patients with XLA.Brain biopsy is an important approach clinically to find out etiology.

ABSTRACT

Objective To evaluate the application of 3.0 T magnetic resonance angiography (MRA) in follow-up after embolization of intracranial aneurysms with stent-assisted coils.Methods From June 2013 to June 2015,32 consecutive patients with subarachnoid hemorrhage due to ruptured intracranial aneurysms underwent stent-assisted coil embolization at the Department of Neurosurgery,the Sixth People′s Hospital of Shenzhen were enrolled retrospectively,including 12 males and 20 female,their mean age was 56±10 years.All patients were confirmed to be solitary intracranial aneurysms by digital subtraction angiography (DSA) before embolization.They were followed up with 3.0 T time of flight MRA (TOF-MRA) and contrast enhanced MRA (CE-MRA) at 1 to 2 years after embolization.DSA findings were served as the golden standard.The effect of aneurysm embolization (stabilization,further embolization,recanalization/recurrence) and patency of the parent arteries (without stenosis/mild stenosis,moderate to severe stenosis and occlusion) were compared.Results (1) The comparisons of evaluating the aneurysmal effects and consistencies of DSA among TOF-MRA,CE-MRA and TOF-MRA+source images after stent-assisted coil embolization were poor (Kappa=0.039,P=0.002),medium (Kappa=0.582,P<0.01),and higher (Kappa=0.615,P<0.01),respectively.(2) The comparison of the consistencies in the patency of the parent artery after stent-assisted coil embolization between TOF-MRA,CE-MRA and DSA were poor (Kappa=0.171,P=0.211;Kappa=0.376,P=0.010).(3) With the DSA findings as reference,the accuracy rates of TOF-MRA,TOF-MRA+source images and CE-MRA for interpretation of aneurysm embolization were 37.5% (12/32),75.0% (24/32),and 71.9% (23/32),respectively.TOF-MRA compared with TOF-MRA+source images and CE-MRA respectively,there were significant differences in the accuracy rates (χ2=9.04,P=0.003;χ2=7.63,P=0.006);there were no significant differences in the accuracy rates between TOF-MRA+source images and CE-MRA (χ2=0.08,P=0.777).(4) With the DSA findings as reference,the accuracy rates of TOF-MRA and CE-MRA for interpretation of the patency of the parent artery were 37.5% (12/32) and 62.5% (20/32) respectively.There was no significant difference in the accuracy rate (χ2=4.67,P=0.097).Conclusions The accuracy rate of 3.0 T CE-MRA for evaluating the embolization effect of intracranial aneurysms after stent-assisted coil embolization was superior to that of TOF-MRA.It can be used as a preferred non-invasive examination during the follow-up.TOF-MRA+source images are equivalent to CE-MRA,however,TOF-MRA and CE-MRA for the evaluation of the accuracy of patency of the parent arteries are low.For positive or indeterminate results of MRA examinations,the individualized analysis should be performed,if necessary,perform DSA examination.

ABSTRACT

Objective To discuss the correlation of Wiskott-Aldrich syndrome (WAS) with autoimmune disease of the central nervous system and its possible pathogenesis by reporting one case of the disease and reviewing related literature.Methods One case of WAS complicated with demyelinating disease of the central nervous system was reported.The patient' s clinical symptoms,laboratory examinations (such as blood tests,immune function tests,etc) and imaging features were analyzed.The patient's blood DNA was extracted and performed gene testing.And related literature was reviewed.Results The patient showed typical clinical symptoms of WAS,including eczema,thrombocytopenia and immune deficiency,complicated with demyelinating disease of the central nervous system.The DNA testing showed C400G > C p.(ALa134Pro) mutation,which is a missense mutation.The 134th amino acid in protein was changed from alanine to proline.The patient also showed the symptoms of demyelinating disease of the central nervous system,which drew our attention.This was the first report on WAS complicated with demyelinating disease of the central nervous system,which was perhaps caused by a gene mutation.Conclusions WAS complicated with demyelinating disease of the central nervous system is possibly resulted from the gene mutation,which leads to the expression disorder of WAS protein.And then non-red hematopoietic cells lead to signal transduction and cytoskeleton recombination disorders in response to environment stimulus,which produces lymphocytes immigration,signal transduction and immune synaps formation disorders.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the feasibility,safety and follow-up results of multiple stents parallel placement and reconstruction technique for treating giant vertebrobasilar dissecting aneurysms.</p><p><b>METHODS</b>Five consecutive patients with giant fusiform vertebrobasilar dissecting aneurysms in Department of Neurology,Chinese People's Liberation Army General Hospital were retrospectively reviewed from April 2011 to October 2013. All patients were diagnosed vertebrobasilar dissecting aneurysms by MRI and digital subtraction angiography (DSA), the aneurysm size ranged 8.2-15.0 mm. All patients were treated by multiple stents parallel placement and reconstruction technique under general anesthesia. In the endovascular treatment process, 2-3 Solitaire or Neuroform self-expandable stents were parallel implanted in the maximum extension segment of the aneurysms to reconstruct the cavity of the aneurysm and solved the problem that the diameter of the intracranial stent is less than the diameter of the aneurysms. Multiple stents parallel placement can keep the stents stable in the cavity. The parallel stent can close the dissection as well as strengthen the aneurysm walls to alleviate the vessel pulsative compression of the brain stem. Furthermore, one of the parallel stents was selected for the main blood flow channel. Based on the main channel, telescope technique was used to completely covering the dissection. It can not only prevent the progress of dissection to normal regions, but also be helpful for blood flow channel reconstruction to reduce the hemodynamic disorders. All Patients received routine antiplatelet therapy before and after endovascular treatment.</p><p><b>RESULTS</b>The operative procedures were succeeded in all patients. Five patients were implanted 18 stents (3 stents in 3 patients; 4 stents in 1 patient; 5 stents in 1 patient; parallel 3 stents in 2 patients; parallel 2 stents in 3 patients). The signs and symptoms of brain stem and posterior group of cranial nerves improved significantly. All patients lived and worked normally and had no recurrent symptoms on follow-up of 6-24 months. All patients performed DSA reexamination at 6-12 months postoperation. The aneurysm size lessened in 2 patients and had no change in 3 patients.</p><p><b>CONCLUSIONS</b>Multiple stents parallel placement and reconstruction technique for treating giant fusiform vertebrobasilar dissecting aneurysms is feasible and have good operation safety. It may control the dilatation of the aneurysm and reduce the probability of thrombosis or hemorrhage. It can improve the patients' clinical symptoms and quality of life in short term follow-up. The long term result need for further follow-up.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the clinical characteristics, surgical principles and treatment options of blood-blister-like cerebral aneurysms in supra-clinoid segment of internal carotid artery.</p><p><b>METHODS</b>Twelve blood-blister-like aneurysms were retrospectively studied including 4 open-surgery cases and 8 endovascular-treated cases from November 2008 to December 2012. Patients comprised 8 female and 4 male patients, whose mean age was 46.6 (range 38-56) years. Eleven patients presented with severe headache as the primary symptom, and 1 patient was found with aneurysm incidentally. Preoperative Hunt-Hess graded 0 in 1 patient, graded I in 5 patients, graded II in 4 patients, and graded III in 2 patients. By DSA examinations, 4 blood-blister-like aneurysms located in anterior wall and 8 in medial-anterior wall of supra-clinoid segment of internal carotid artery. Open surgical treatment included direct clipping, trapping, or wrapping and interventional treatment included stent-assisted coiling or simple stent placement. Intra-operative electroencephalogram and somatosensory evoked potentials monitoring was regularly used. Microvascular Doppler ultrasonography and indocyanine green videoangiography were used to assess blood flow in parent and branch vessels. The patients were followed up at 6 months by CT angiography (CTA) examination in outpatient clinic.</p><p><b>RESULTS</b>For 4 open surgeries, 2 aneurysms were directly clipped, 1 was trapped and 1 was wrapped. The patient underwent trapping paralyzed postoperatively. For endovascular treatment, 6 patients were coiled assisted with stents and 2 patients were treated with simple stent placement. All the patients were followed with a mean follow-up time of 16 months (range, 6-61 months). At 6 months follow-up, 3 out of 4 surgical treated patients had good outcome and 1 was moderately severe disabled by modified Rankin scale; 1 patient underwent wrapping recurred and was transferred to endovascular treatment. Of the 6 patients treated with stent-assisted coiling, 4 patients were recurrent and coil replacements were performed. Two patients with simple stent placement had no recurrences.</p><p><b>CONCLUSIONS</b>Blood-blister-like aneurysm is a special type of complex cerebral aneurysm. Comprehensive understanding of blood-blister-like aneurysm is the key to successful treatment.Open surgery is difficult procedure with high risk and complications while stent-assisted coiling has a high recurrent rate. To date, neither is the safe and effective treatment option.</p>

ABSTRACT

BACKGROUND: Functional injury of brain and limb induced by hemorrhage of cerebral arteriovenous malformation could be restored by rehabilitative treatment OBJECTIVE: To investigate the curative effect of rehabilitation on restoration of the functional injury of the brain and limbs induced by bleeding of hemorrhage cerebral arteriovenous malformation (AVM) after embolization.DESIGN: Case analysis.SETTING: Department of Interventional Medicine of General Hospital of Chinese PLA.PARTICIPANTS: From January 1996 to December 2001, a total 56 patients who were diagaosed as cerebral hemorrhage or intraventricle hemorrhage by CT or MRI scanning was selected from General Hospital of Chinese PLA.METHODS: All 56 patients with cerebral arteriovenous malformation were diagnosed by DSA. Rehabilitative treatment was performed with α-butyl cyanoac-rylate or radian surgery. Rehabilitative therapy were as follow: [1] Electric stimulate: S J-Ⅱ type nerve-muscle therapy instrument was used to stimulate the muscles (flexor and extensor) of limbs in the involved side, intensity of which is from weak to strong and frequency of which was from 2 to 3 or 4 per day; [2] Acupuncture: The selected points are:Fengchi, Fengfu, Yintang, Shangxing, Baihui, Quchi, Waiguan, Hegu,Huantiao, Zusanli, Yanglingquan, Sanyinjiao, Taichong, et al. In those who suffered aphasia, lianquan, Jinjin, Yuye were selected. Once a day and a period of treatment was 2 weeks; [3] physical training: the passive movement on the joint in the involved limbs were performed in grade 0 to 1 of muscle strength, the balance training of sitting on bed or standing beside the bed in grade 1 to 2, walking training in grade 2 to 3. The training intensity should be from weak to strong gradually. The items of observation were the improvement in speaking, sense and activity in limbs in the involved side. Evaluation of myodynamia was referenced to 6 grading method of Lovett.MAIN OUTCOME MEASURES: [1] the degree of embolism; [2] the degree of speaking fluency, the sense of limbs and the strength of the muscles of the limbs.RESULTS: Totally 56 cases entered the final analysis without any loss. [1]Degree of embolism: Among 56 cases, 100% focus was eliminated for 77% in 43 cases, 90% was eliminated for 12% in 7 cases and 60%-80% was eliminated for 11% in 6 cases. [2] Fluency of language: Before the treatment of rehabilitation, they suffered different degree impediment of speaking in 14 cases, improvement in 14 cases and obvious improvement in 11 cases. [3] Sense of limb:The sense of limbs was improved in 23 cases and 18 of them improved obviously. [4] Strength of muscles: The strength of muscles in 0 to 1 grade in 3 cases, 1 to 2 grade in 11 cases, 2 to 3 grade in 15 cases. But after the treatment of rehabilitation, speaking ability was improved in 14 cases, and 11 of them improved obviously. The strength of muscles was. resumed to 2 or 3 grade from 0or 1 grade in 2 cases, and to 4 grade in 21 cases and 5 grade in 6 cases.CONCLUSION: Endovascular embolization is a minimal traumatic, the rehabilitative therapy which is secure and effective method for treatment of high risk cerebral AVM, can promote motion function, language function and ability of activity of daily living, and quality of life of patients with cerebral arteriovenous malformation after embolism.

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the experience of treating the obliteration of the cerebral venous sinus in 17 patients by using direct thrombolysis and stent angioplasty.</p><p><b>METHODS</b>All 17 patients with thrombosis and stenosis of the venous sinus were confirmed by digital subtraction angiography. Of these 3 patients had thrombosis in a single sinus and 14 had thrombosis in multiple sinuses. The circulating time was prolonged for over 13 seconds. The micro-catheter was preserved in the sinus for 5 days, followed by infusion of urokinase 1.5 million units and oral warfarin 3-5 mg each day. Stent angioplasty was done for 4 patients with obvious stenosis of the venous sinus detected by DSA after thrombosis.</p><p><b>RESULTS</b>After contact thrombosis and stent angioplasty in sinuses of the 17 patients, remarkable recanalization of obliterated sinuses was achieved. After treatment, intracranial hypertension pressure (ICP) returned to normal in 7 patients, and 8 thrombosis relapsed in different degree after 7 days. Anticoagulation was prescribed. Only 2 patients showed the ICP above 280 mm H(2)O. No obvious relapse was found in 15 patients during the follow-up for 3-60 months.</p><p><b>CONCLUSION</b>Our results demonstrated that successive thrombolysis and stent angioplasty for occlusion and thrombosis of the venous sinus are effective in promoting drainage of cerebral venous blood and rapidly decreasing ICP.</p>

ABSTRACT

Fourteen patients with vascular stenosis in carotid artery system were treated using angioplasty and stenting.The stenosis was located at bifurcation in 6 cases, intracranial internal carotid artery in 3, horizontal segment of middle cerebral artery in 3, and original segment of common carotid artery in 2. Depending on the long and degree of stenosis,different types of SMART stents and Biodivysio stents were selected for the endovascular angioplasty via the femoral approach in 13 cases. Balloon dilatation angioplasty was performed in one case. All the angioplasties in 14 cases were successfal. Different improvement was achieved in patients with neurological defects and no stroke was found in NIHSS after endovascular angioplasty. Following up 3 to 14 months, there was no TIA and other ischemic neurological defect. The primary results of our group showed that endovascular angioplasty and stenting are effective and safe for carotid stenosis. It should be one of the favorable choices for the treatment of vascular stenosis in catotid artery system.

ABSTRACT

Objective To discuss the image characters and the technical manipulation of endovascular embolization for cerebral AVM with bleeding. Methods The cerebral AVMs with bleeding in 56 cases were confirmed by CT, MRI, and whole cerebral DSA. Depended on the nidus of AVM, the superselective endovascular embolization with NBCA or embolization combined with radiological surgery was chosen. Results The nidus was eliminated for 100% in 36 cases after embolization for 1 to 3 processes. The rebleeding was found in 2 cases with new growth and survival aneurysm in nidus during the follow-up period and treatment with X-knife, and was cured by the second embolization. Conclusion The main causes of AVM bleeding included aneurysm and aneurysm-like dilation beside and located at the nidus, fine draining veins, and growth in the ventricles. To prevent the brain from bleeding, it is favourable to eliminate the aneurysm in AVM during embolization.

ABSTRACT

Eighty-one patients with acute upper digestive tract bieeding were treated in the intensive care unit (ICU) of the neuro surgery between Mar. 1986 and Apr. 1992. Of them 75 cases were treated by routine therapy, the cure being in 35 (43.2%), improvement in 24 (29.6%), death 16 (19.75%). While digital subtraction angiography (DSA) was applied in 3 patients repeated bleeding, and the bleeding seats were shown on it. Consequentially, two of the 3 cases stopped bleeding and other one got impovement by embolization procedure. In addition, Omeprazole, a new inhibitor of gastric acid secretion, was used in 3 bleeding cases, with a satisfactory effect. The authors believe that ICU is most favourabie to medical management of such patients.

ABSTRACT

Objective To observe the effect of selective intra-arterial thrombolytic therapy for central retinal artery thrombosis. Methods 100 000-250 000U of urokinase were injected into the ophthalmic artery via a catheter in the ophthalmic artery or the internal carotid artery to carry out the thrombolytic therapy. Results The visual acuity was significantly improved from light perception or finger counting to 0.1 in 8 of a total of 26 cases, partially improved in 10 cases, and no change in vision in 8 cases. The time interval from the onset of the disease to thrombolysis was within 8 days in the 18 patients who showed improvement, 3 of them showed significant improvement, of whom 2 received the treatment within 3 days. Conclusion Selective intra-arterial thrombolytic therapy is effective for the treatment of central retinal artery thrombosis. The effect was closely related to the time interval from the onset of the disease to thrombolysis. The thrombolytic therapy should be carried out as soon as possible.
