103. The Factors Associated with Outcomes in Surgically Managed Ruptured Cerebral Aneurysm (PubMed)

The Factors Associated with Outcomes in Surgically Managed Ruptured Cerebral Aneurysm Ruptured cerebral aneurysm is a life-threatening condition that requires urgent medical attention. In Malaysia, a prospective study by the Umum Sarawak Hospital, Neurosurgical Center, in the year 2000-2002 revealed an average of two cases of intracranial aneurysms per month with an operative mortality of 20% and management mortality of 25%. Failure to diagnose, delay in admission to a neurosurgical centre (...) , and lack of facilities could have led to the poor surgical outcome in these patients. The purpose of this study is to identify the factors that significantly predict the outcome of patients undergoing a surgical clipping of ruptured aneurysm in the local population.A single center retrospective study with a review of medical records was performed involving 105 patients, who were surgically treated for ruptured intracranial aneurysms in the Sultanah Aminah Hospital, in Johor Bahru, from July 2011

104. Management of Recurrent Cerebral Aneurysm after Surgical Clipping : Clinical Article (PubMed)

Management of Recurrent Cerebral Aneurysm after Surgical Clipping : Clinical Article Surgical clipping of the cerebral aenurysm is considered as a standard therapy with endovascular coil embolization. The surgical clipping is known to be superior to the endovascular coil embolization in terms of recurrent rate. However, a recurrent aneurysm which is initially treated by surgical clipping is difficult to handle. The purpose of this study was to research the management of the recurrent cerebral (...) radiographs and operative findings, several main causes of the recurrent cerebral aneurysm were found. One case was incomplete clipping, five cases were clip slippage, and eight cases were fragility of vessel wall near the clip edge.This study revealed main causes of the recurrent aneurysm and contributing risk factors to be controlled. To manage those risk factors and ultimately prevent the recurrent aneurysm, neurosurgeons have to be careful in the technical aspect during surgery for a complete clipping

105. Arterial Spin Labeling Imaging of a Giant Aneurysm Leading to Subarachnoid Hemorrhage following Cerebral Infarction (PubMed)

Arterial Spin Labeling Imaging of a Giant Aneurysm Leading to Subarachnoid Hemorrhage following Cerebral Infarction An 83-year-old Japanese man was admitted with dysarthria and right hemiparesis. He had had a large intracranial aneurysm on the left internal carotid artery 5 years before admission and had been followed up under conservative treatment. On admission, diffusion-weighted imaging revealed a hyperintense signal on the left anterior choroidal artery territory. Time-of-flight magnetic (...) resonance angiography demonstrated poor visibility of the middle and anterior cerebral arteries and the inferior giant aneurysm, suggesting distal emboli from aneurysm thrombosis or a reduction of blood outflow due to aneurysm thrombosis. Arterial spin labeling (ASL) signal increased in the giant aneurysm, suggesting blood stagnation within the aneurysmal sac, and decreased in the left hemisphere. We diagnosed cerebral infarction due to aneurysm thrombosis, and started antithrombotic therapy. On day 2

106. A case report on middle cerebral artery aneurysm treated by rapid ventricular pacing: A CARE compliant case report. (PubMed)

A case report on middle cerebral artery aneurysm treated by rapid ventricular pacing: A CARE compliant case report. Cerebral aneurysm is a common cause of intracranial hemorrhage, stroke, and death. It is treated with vascular surgeries, such as coil embolism and artery clipping. However, surgery itself is a risk factor that may cause rupture of aneurysm, and leads to irreversible brain damage, and even death. Rapid ventricular pacing (RVP) is a procedure that temporarily lowers blood pressure (...) by increasing heart rate and reducing ventricular filling time. RVP has been widely used to reduce blood vessel tension in many cardiovascular surgeries.A 46-year-old man came to our hospital with intermittent right-side headache for 5 years, and left lower limb numbness for 3 months.Magnetic resonance imaging (MRI) of the head and digital subtraction angiography confirmed the diagnosis of right middle cerebral artery (MCA) aneurysm.Considering the large size of this MCA aneurysm, RVP was used to reduce

107. Cerebral revascularization for the management of complex intracranial aneurysms: a single-center experience. (PubMed)

Cerebral revascularization for the management of complex intracranial aneurysms: a single-center experience. OBJECTIVEBecause simple intracranial aneurysms (IAs) are increasingly treated endovascularly, neurovascular surgery has become focused on complex IAs that may require deconstructive aneurysm therapy with concomitant surgical bypass. The authors describe the decision-making process concerning cerebral revascularization and present outcomes that were achieved in a large case series (...) of complex IAs managed with cerebral revascularization and parent artery occlusion.METHODSThe authors retrospectively reviewed the medical records, including neuroimaging studies, operative reports, and follow-up clinic notes, of all patients who were treated at the National Brain Aneurysm Center between July 1997 and June 2015 using cerebral revascularization as part of the management of an IA. They recorded the location, rupture status, and size of each IA, as well as neurological outcome using

Association between vasoactive peptide urotensin II in plasma and cerebral vasospasm after aneurysmal subarachnoid hemorrhage: a potential therapeutic target. OBJECTIVECerebral vasospasm (VS) is a severe complication of aneurysmal subarachnoid hemorrhage (SAH). Urotensin II (UII) is a potent vasoactive peptide activating the urotensin (UT) receptor, potentially involved in brain vascular pathologies. The authors hypothesized that UII/UT system antagonism with the UT receptor antagonist/biased (...) patients with VS (median 66 pg/ml [IQR 30-110 pg/ml]) and SAH patients without VS (27 pg/ml [IQR 15-46 pg/ml], p < 0.001) but no significant difference between VS patients and healthy volunteers (44 pg/ml [IQR 27-51 pg/ml]) or between non-VS patients and healthy volunteers.CONCLUSIONSThe results of this study suggest that UT receptor antagonism with urantide prevents VS and improves neurological outcome after SAH in mice and that an increase in plasma UII is associated with cerebral VS subsequent

109. Impact of isolated cerebral perfusion technique for aortic arch aneurysm repair in elderly patients. (PubMed)

Impact of isolated cerebral perfusion technique for aortic arch aneurysm repair in elderly patients. In aortic surgery, a severely atherosclerotic aorta is a known risk factor for perioperative stroke. The authors adopted a novel procedure of selective cerebral perfusion, named isolated cerebral perfusion (ICP), for the prevention of stroke during aortic arch operations.Between January 2010 and June 2016, 48 patients (mean age, 80 ± 3 years) at Yokohama City University Medical Center, Yokohama (...) into the LCCA were performed. Extracorporeal circulation through the bilateral axillary arteries and selective cerebral perfusion to the LCCA were simultaneously started. Finally, at a bladder temperature of 25°C, clamping of the brachiocephalic and left subclavian arteries was performed.Preoperative evaluation by enhanced computed tomography confirmed that 62.2% of patients had severely atherosclerotic aortas and 37.8% had shaggy aortas. The overall 30-day mortality rate was 2.1%, whereas that for elective

110. Computer-aided analysis of middle cerebral artery tortuosity: association with aneurysm development. (PubMed)

Computer-aided analysis of middle cerebral artery tortuosity: association with aneurysm development. OBJECTIVEBlood vessel tortuosity may play an important role in the development of vessel abnormalities such as aneurysms. Currently, however, there are no studies analyzing the impact of brain blood vessel tortuosity on the risk of aneurysm formation. Therefore, the authors performed a computer-aided analysis of middle cerebral artery (MCA) tortuosity, especially among patients diagnosed (...) cerebral artery aneurysm formation is strongly associated with blood vessel tortuosity parameters, which can potentially be used to screen for patients at risk for MCA aneurysm formation.

113. Basal ganglion hematoma evacuation and clipping of middle cerebral artery aneurysm by neuroendoscopy: A case report. (PubMed)

Basal ganglion hematoma evacuation and clipping of middle cerebral artery aneurysm by neuroendoscopy: A case report. Basal ganglia hematomas resulting from the rupture of aneurysms of the distal middle cerebral artery (MCA) are extremely rare and are usually treated by craniotomy. To date, only 5 cases of MCA aneurysm have been treated using neuroendoscopy, and none of these cases involved hematomas. For the first time, we report a special case in which neuroendoscopy was used to evacuate (...) a hematoma and clip an aneurysm at the same time.A massive basal ganglia hematoma in a 60-year-old man was evacuated using neuroendoscopy, and a distal MCA aneurysm was discovered and clipped successfully under the neuroendoscopy during the operation.Basal ganglia hematoma, Distal MCA aneurysm.The patient's left pupil shrunk, and his state of consciousness gradually improved after the operation.Our experience with this patient demonstrates that an aneurysm originating in the distal MCA and accompanied

114. Cerebral embolization during endovascular infrarenal, juxtarenal, and suprarenal aortic aneurysm repair, high-risk maneuvers, and associated neurologic outcomes. (PubMed)

Cerebral embolization during endovascular infrarenal, juxtarenal, and suprarenal aortic aneurysm repair, high-risk maneuvers, and associated neurologic outcomes. Risk factors for postoperative cognitive decline after noncardiac surgery are multifactorial and poorly understood. Evidence suggests that perioperative microembolic damage to the brain on movement of wires and catheters during endovascular aortic procedures may play an important role. Endovascular aortic aneurysm repair requires (...) invasive manipulation of wires and cannulas within the aorta, but research into cerebral emboli during aortic aneurysm repair and cognitive or neurologic injury is scarce and limited to thoracic aneurysms. This study prospectively studied embolic phenomena detected in the middle cerebral artery during infrarenal, juxtarenal, and thoracic endovascular aortic repair (TEVAR) and investigated links to delirium, stroke, and postoperative cognitive decline.There were 60 patients who received continuous left

119. Bedside cerebral microdialysis monitoring of delayed cerebral hypoperfusion in comatose patients with poor grade aneurysmal subarachnoid haemorrhage. (PubMed)

Bedside cerebral microdialysis monitoring of delayed cerebral hypoperfusion in comatose patients with poor grade aneurysmal subarachnoid haemorrhage. Delayed cerebral ischaemia (DCI) is frequent after poor grade aneurysmal subarachnoid haemorrhage (SAH). Owing to the limited accuracy of clinical examination, DCI diagnosis is often based on multimodal monitoring. We examined the value of cerebral microdialysis (CMD) in this setting.20 comatose SAH participants underwent CMD monitoring-for hourly (...) sampling of cerebral extracellular lactate/pyruvate ratio (LPR) and glucose-and brain perfusion CT (PCT). Patients were categorised as DCI when PCT (8±3 days after SAH) showed cerebral hypoperfusion, defined as cerebral blood flow <32.5 mL/100 g/min with a mean transit time >5.7 s. Clinicians were blinded to CMD data; for the purpose of the study, only patients who developed cerebral hypoperfusion in anterior and/or middle cerebral arteries were analysed.DCI (n=9/20 patients) was associated with higher

120. Predictive modeling and in vivo assessment of cerebral blood flow in the management of complex cerebral aneurysms. (PubMed)

Predictive modeling and in vivo assessment of cerebral blood flow in the management of complex cerebral aneurysms. Cerebral aneurysms are weakened blood vessel dilatations that can result in spontaneous, devastating hemorrhage events. Aneurysm treatment aims to reduce hemorrhage events, and strategies for complex aneurysms often require surgical bypass or endovascular stenting for blood flow diversion. Interventions that divert blood flow from their normal circulation patterns have (...) the potential to result in unintentional ischemia. Recent developments in computational modeling and in vivo assessment of hemodynamics for cerebral aneurysm treatment have entered into clinical practice. Herein, we review how these techniques are currently utilized to improve risk stratification and treatment planning.© The Author(s) 2016.
