Filter by:To evaluate the clinical benefits and risks of hybrid operating techniques in management of complex intracranial aneurysms, which could coexists with multiple risk factors.
To evaluate the clinical benefits and risks of hybrid operating techniques in management of intracranial aneurysms with coexistence of atherosclerotic intracranial arterial stenosis.
To evaluate the effect of rapid ventricular pacing on the oxygenation of the brain in patients scheduled for cerebral aneurysm clipping surgery or arteriovenous malformation surgery.
Rapid ventricular pacing (RVP) is a technique to obtain flow arrest for short periods of time during dissection or rupture of the aneurysm. RVP results in an adequate fall in blood pressure which presents as an on-off phenomenon. However it is not clear whether repetitive periods of pacing are harmless for the patient. Silent cardiac and cerebral infarcts may be undetected. The investigators will study the safety of RVP, particularly for the heart and the brain.
Investigate the ability of the intra-operative, intra-aneurysmal flow evaluation to assist with the treatment of intracranial large aneurysms using Embolization Device(s)
This is a registry study of the natural course of unruptured intracranial aneurysms (UIA). In addition, the investigators will analyze the benefit-risk of antithrombotic or anticoagulant therapy in patients with unruptured intracranial aneurysms associated with ischemic heart disease or ischemic cerebrovascular disease. The investigators aim to use research data to create a China national database of UIA
This is a prospective, multicenter, observational study, aiming at comparing the Safety and effectiveness among the different surgical treatment of unruptured intracranial aneurysms in China, so as to improve the diagnosis and treatment of unruptured intracranial aneurysms.
This study aims at clarifying the current situation of Emergency treatment of aneurysmal subarachnoid hemorrhage (SAH) in China, and analyzing the safety and efficacy of the treatment strategy between interventional treatment and open surgery, so as to improve the diagnosis and treatment of aneurysmal SAH.
During surgery, electrophysiological signals will be acquired with the instrument (ISIS IOM, NeuroExplore, Software Version 4.4, Inomed) already in use at the Neurosurgery Service of the Neurocentro of the Hospital Civic Italian Switzerland in Lugano. Simultaneously to Somatosensorial Evoked Potential (SEP) will also be recorded the Electroencephalography (EEG) activity with the same detection of locations. For the purposes of the study the signals transmitted to the neurosurgeon through the hardware and the corresponding assessments done by the neurophysiologist responsible for intraoperative monitoring will be recorded. It will also be kept track of procedures performed during surgery.
The purpose of this study is to use a wire with a Doppler tip to measure blood flow in vessels in the brain and determine hemodynamic factors associated with treatment success or failure. Many neurological diseases cause abnormal blood flow in the brain in specific vessels. The special wire used in this study is place into brain blood vessels during standard of care procedure to treat such diseases, and blood flow parameters (such as velocity and pressure) are measured to gain better understanding of these neurological diseases.
