It is a broad and relative concept and there is few consistent medical data to validate its benefits. In this manner, this is the first clinical trial in Brazil questioning the safety of the of minimally invasive surgery to treat incidental cerebral aneurysms of the anterior circulation. For countries like Brazil, the indirect demonstration of reduction in hospital costs through lower hospital stays is a breakthrough to provide better health for the entire population.\n\nPatients with the diagnosis of incidental brain aneurysms of the anterior circulation will be recruited from the spontaneous demand of the Hospital das Clínicas of University of São Paulo Medical School. The investigators expect to recruit 60 patients for the experimental group and 60 for the control group.\n\nIn the study group patients will be submitted to a minimally invasive approach (transpalpebral mini fronto-orbital craniotomy or modified minipterional craniotomy). All patients in this group will be submitted to surgery starting at 8 o'clock in the morning. After 6 hours of the end of surgery, all patients will have a control CT scan and if the result is adequate, they are going to be discharged from the ICU with no IV drugs. The hospital discharge will be in the next day. The control group are patients that will be submitted to a classical pterional craniotomy with hospital discharge occurring in 4-5 days.\n\nAll patients will be submitted to the standard care offered by the Hospital das Clinicas. All surgical and ambulatory data will be collected by the main investigators (Dr. Mauricio Mandel and Dr. Eberval Figueiredo). The adverse events will be promptly reported to the chair of the department and to the CAPPESQ (the ethics committee of the hospital).\n\nAmbulatory data will be collected during the regular post operative medical appointments and a web based questionnaire. The post operative follow-up is unified in only one ambulatory center and day (thursdays mornings).\n\nStatistical analysis will compare primary and secondary objectives of the two groups, as specified in the study protocol."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Patients with the diagnosis of incidental unruptured cerebral aneurysms (4mm to 2cm)\n\nExclusion Criteria:\n\n* Patients who do not have adequate family care during the immediate post-operative period (the patient's family must commit to stay with the patient in the first five days after hospital discharge)\n* Patients who are unable to communicate by telephone\n* People with cardiovascular disease, liver or kidney failure.\n* Pregnant women or breastfeeding\n* Patients with coagulation abnormalities\n* Patients with High Surgical Risk evaluated by different risk scores (ASA, AHA, Goldman, Detsky)"}, 'identificationModule': {'nctId': 'NCT02345395', 'acronym': 'MININCRUSP', 'briefTitle': 'Safety Study of Minimally Invasive Approaches to Unruptured Anterior Circulation Aneurysms', 'organization': {'class': 'OTHER', 'fullName': 'University of Sao Paulo General Hospital'}, 'officialTitle': 'Safety Study of Minimally Invasive Approaches to Unruptured Anterior Circulation Aneurysms', 'orgStudyIdInfo': {'id': 'TRANSPALPEBRAL USP'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Transpalpebral Approach', 'description': 'Aneurysm Clipping - Patients will be submitted to a Transpalpebral Approach to Unruptured Anterior Circulation Aneurysm and they will be discharged from the hospital on the next day.', 'interventionNames': ['Procedure: Aneurysm Clipping']}, {'type': 'EXPERIMENTAL', 'label': 'NanoPterional Approach', 'description': 'Aneurysm Clipping - Patients will be submitted to a Modified MiniPterional Approach (Nanopterional) to Unruptured Anterior Circulation Aneurysm and they will be discharged from the hospital on the next day.', 'interventionNames': ['Procedure: Aneurysm Clipping']}, {'type': 'SHAM_COMPARATOR', 'label': 'Classical Pterional Craniotomy', 'description': 'Aneurysm Clipping - Patients will be submitted to a Classical Pterional Approach to Unruptured Anterior Circulation Aneurysm and they will be discharged from the hospital 4-5 days after the procedure.', 'interventionNames': ['Procedure: Aneurysm Clipping']}], 'interventions': [{'name': 'Aneurysm Clipping', 'type': 'PROCEDURE', 'description': 'All Patients will be submitted to a surgical intervention in order to clip their unruptured brain aneurysm', 'armGroupLabels': ['Classical Pterional Craniotomy', 'NanoPterional Approach', 'Transpalpebral Approach']}]}, 'contactsLocationsModule': {'locations': [{'zip': '05403-000', 'city': 'São Paulo', 'state': 'São Paulo', 'status': 'RECRUITING', 'country': 'Brazil', 'contacts': [{'name': 'Mauricio Mandel, MD', 'role': 'CONTACT', 'email': 'mauricio.mandel@gmail.com', 'phone': '55 11 996299224'}, {'name': 'Ester M Tomazini', 'role': 'CONTACT', 'email': 'ester.t@hc.fm.usp.br', 'phone': '2661-7152/8014'}, {'name': 'Mauricio Mandel, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Eberval G Figueiredo, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR'}], 'facility': 'Hospital das Clínicas of University of São Paulo Medical School', 'geoPoint': {'lat': -23.5475, 'lon': -46.63611}}], 'centralContacts': [{'name': 'Mauricio Mandel, MD', 'role': 'CONTACT', 'email': 'mauricio.mandel@gmail.com', 'phone': '55 11 996299224'}, {'name': 'Ester M Tomazini', 'role': 'CONTACT', 'email': 'ester.t@hc.fm.usp.br', 'phone': '55 11 2661-7152/8014'}], 'overallOfficials': [{'name': 'Eberval G Figueiredo, MD, PhD', 'role': 'STUDY_DIRECTOR', 'affiliation': 'University of Sao Paulo'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Sao Paulo General Hospital', 'class': 'OTHER'}, 'collaborators': [{'name': 'Fundação de Amparo à Pesquisa do Estado de São Paulo', 'class': 'OTHER_GOV'}], 'responsibleParty': {'type': 'SPONSOR'}}}, 'annotationSection': {'annotationModule': {'unpostedAnnotation': {'unpostedEvents': [{'date': '2020-04-16', 'type': 'RELEASE'}, {'date': '2020-05-04', 'type': 'RESET'}, {'date': '2020-05-06', 'type': 'RELEASE'}, {'date': '2020-05-07', 'type': 'UNRELEASE'}, {'date': '2020-05-08', 'type': 'RELEASE'}, {'date': '2020-05-13', 'type': 'UNRELEASE'}, {'date': '2020-06-23', 'type': 'RELEASE'}, {'date': '2020-07-07', 'type': 'RESET'}], 'unpostedResponsibleParty': 'University of Sao Paulo General Hospital'}}}}
