Journal of military pharmaco-medicine no9-2018 CLINICAL FEATURES AND EFFECTS OF INTRAVASCULAR INTERVENTION OF EXPANDED ANEURYSM ON THE BROKEN TENTORIUM Nguyen Duy Thanh1; Nguyen Hung Minh2; Vu Van Hoe2 SUMMARY Objectives: To describe the clinical features and effects of intravascular intervention of expanded aneurysm on the broken tentorium Subjects and methods: Cross-sectional descriptive study of 65 patients, who were diagnosed with expanded aneurysm on the broken tentorium at 115 People’s Hospital from January 2011 to August 2017 Results: The most common age was from 40 to 60 years old (49.2%) Women had a higher incidence of disease than men (66.2%); for prevalence of high blood pressure, clinical symptoms included sudden headache of 98.5%, vomiting of 56.9% and nausea of 49.2%, meningitis of 69.2%, sensory impairment of 43.1%, seizures of 3.1%, focal neurology of 35.4%, drooping eyelid of 62% and language disorders of 9.2% Clinical symptoms at the time of hospitalization: 12.3% for Hunt-Hess level I, 46.2% for level II, 35.4% for level III and 6% for level IV Treatment of expanded aneurysm on the broken tentorium with coils and insertion ball had 29 cases (45%), obstruction with coils and stents had 34 cases (52%) and change in flow had cases (3%) Total obstruction was 87%, partial obstruction was 5%, change in flow was 3% and failure was 5% Right ventricle dilatation with VP shunt was case, pneumonia was cases and residual aneurysm was case These results were assessed in Glasgow, positive at 71%, negative at 25% and mortality at 5% According to Hunt-Hess I - III, 46/65 patients were positive at 71.5%, and Hunt-Hess IV - V were negative at 4.6% * Keywords: Intracranial aneurysm; Hemorrhagic meningine; Clinical features; Intravascular intervention INTRODUCTION Intracranial aneurysm is a common system of cerebral arteries Intracranial aneurysm accounted for to 8% [5] of the population, most of the intracranial aneurysms were detected after they had broken The rupture of the intracranial aneurysm was a type of stroke with a severe neurological disease, rapid and complex progression, causing many complications, sequelae as well as high mortality The rupture of the intracranial aneurysm usually occurred suddenly, severe headache, with or without meningeal signs and local or total neurological dysfunction After rupture, about 10% of patients died before being admitted The number of surviving patients with primary bleeding was conservative, and the recurrent bleeding was the main cause of death, especially in the first two weeks 115 People′s Hospital 103 Military Hospital Corresponding author: Nguyen Duy Thanh (thanhndngoaitk@gmail.com) Date received: 19/09/2018 Date accepted: 21/11/2018 172 Journal of military pharmaco-medicine no9-2018 In fact, the rupture of intracranial aneurysms was a tragedy for patients, families and society Therefore, the rapid diagnosis, timely intervention and removal of the intracranial aneurysms from the brain circulation cycle by intravascular intervention to seal the intracranial aneurysms with coils (coil) to prevent patients from a serious surgery to open the skull bulging the intracranial aneurysms was a matter of concern in connection with our topic The aims of this study were: To describe the clinical features and effects of intravascular intervention of expanded aneurysm on the broken tentorium SUBJECTS AND METHODS Subjects Patients diagnosed with expanded aneurysm on the broken tentorium were treated at 115 People's Hospital from January 2011 to August 2017 * Criteria for selection: All patients with the expanded aneurysm on the broken tentorium were diagnosed clinically Patients treated with intravascular intervention at 115 People's Hospital Clinical classification of Hunt-Hess I, II, III Obstruction of aneurysm with coils and stents across the neck for spherical aneurysm (aneurysm/neck ratio < 1.5) [2] Congestion of diamond aneurysm and giant aneurysm Patients and their families agreed to treatment * Criteria for exclusion: Patients diagnosed with the rupture of the intracranial aneurysm on the tentorium were treated surgically Patients were diagnosed with the rupture of the intracranial aneurysm on the narrow neck Patients with severe medical and clinical illnesses of Hunt - Hess five, did not accept this treatment method Methods Uncontrolled cross-sectional clinical descriptive study * Steps: Epidemiology, clinical features of the ruptured intracranial aneurysm, intravascular intervention, complications after intervention and treatment results RESULTS AND DISCUSSIONS Epidemiology * Age: The majority of patients between 40 - 60 years of age (30 patients), accounted for 46.2%, more than 60 years of age (32 patients) accounted for 40.2% and less than 40 years of age (3 patients) accounted for 4.6%, comparing with some authors: Nguyen The Hao [1], Nguyen Son [2], L Pierot [6], there was no difference, almost 40 - 60 years * Gender: In our study, women accounted for 86.2% (56 patients), and men accounted for 13.8% (9 patients) Comparing with some authors: Nguyen The Hao [1], Greenberg [5], Kassell [7], there was no different about gender But in our study, the rate of women was important, perhaps our study is not enough 173 Journal of military pharmaco-medicine no9-2018 Clinical features of the ruptured intracranial on the tentorium * Medical history: 26 patients (40%), less than in the study by Nguyen Thi Kim Lien (70%) [4] It can be explained that only a few of patients in city can go to the hospital early before complication * Clinical symptoms at onset: Figure 1: Medical history distribution Patients with a history of hypertension were 43 patients (66.2%), patients with a history of hemorrhagic meninge (13.8%), 20 patients with no medical history (30.8%) and patients with other medical history (12.3%) The majority of patients in our study had history of hypertension In comparing with the other authors like: Nguyen Son 53.8% [2], Le Van Thinh 56% [3] There were no difference * Time from onset to admission: The fastest time was 24 hours and the latest time was 30 days Average time 4.48 ± 6.34 days (median: days) In our study group, 26 patients (40.0%) were hospitalized for the first 24 hours, 20 patients (30.8%) were hospitalized for - days, 11 patients (16.9%) were hospitalized for - days and patients (12.3%) were hospitalized for more than 10 days It was shown that the rupture of the intracranial aneurysm was progressive and sudden In first 24 hours, there were 174 The two most common symptoms of hemorrhagic meninge were sudden headache in 64 patients (98.5%), vomiting in 37 patients (56.9%); nausea: 32 patients (49.2%); disorder of autonomic nervous system: patients (9.2%); convulsion: patients (3.1%) and drooping eyelids: patients (6.2%) Our results were consistent with studies by Nguyen Son (90.91%) [2], Nguyen The Hao (83.5%) [1], Le Van Thinh (98.0%) [3] * Clinical symptoms at admission: In our study group, meningiomas accounted for a majority (45 patients = 69.2%), 28 patients (43.1%) with disorder of consciousness perception and 23 patients (35.4%) with focal neurological syndrome; blood pressure ≥ 150 mmHg: 23 patients (35.4%); polio III: patients; signs of focal neuropathy: 23 patients (35.4%); hemiplegia: 20 patients; language disorder: patients (9.2%) and stiffness: 45 patients (69.2%) * Clinical levels at admission according to Hunt-Hess: 61 patients (93.8%) hospitalized with clinical levels from to 3, patients (6.2%) with level In our study, Hunt-Hess level and was majority in the comparing with studies by Yasargil (10.7%) [8], Heros (19.6%) [9], maybe the patients with hemorrhagic meninge were late hospitality Journal of military pharmaco-medicine no9-2018 Intravascular intervention In our study group, there were 36 patients (55.4%) with stent obstruction and 29 patients (44.6%) were supported by insertion balls using coils blockage of blood vessels; neck stent: 34 patients; stent (change in flow): patients 57 patients (87.7%) with intracranial aneurysm were intervened with total intravascular obstruction, patients (4.6%) with partial intravascular obstruction, patients (3.1%) with change in flow, patients (4.6%) with failure Incidents and complications after intervention * Complications after intervention: Incidents after intervention in our study group had patient (1.5%) with ventricular dilatation, patient (1.5%) with residual aneurysm and patients (13.8%) with pneumonia Treatment results We monitored and re-examined all patients (100%) Our follow-up time occurred until all of them were discharged from the hospital * Interventions relevant to patient age according to GOS: Table 1: Correlation between age groups and patients GOS Less than 55 years of age, n (%) ≥ 55 years of age, n (%) Total n (%) Very good (level V) 15 71.4 18 40.9 33 50.8 Good (level IV) 19.0 20.5 13 20.0 Average (level III) 9.5 10 22.7 12 18.5 Negative (level II) 9.1 6.2 Mortality (level I) 6.8 4.6 Total 21 44 p value 65 0.008 We found that the negative results were higher in the old age group, the clinical findings after intervention and age were statistically significant with p = 0.008 (< 0.05) * Interventions and pre-intervention status: Table 2: GOS findings and clinical pre-intervention status (Hunt-Hess clinical scale) Clinical pre-intervention status Level -
