Abstract The main danger of a brain aneurysm (a sack-like bulge on the vessel wall) is that in event rupture severe hemorrhage can occur which may cause death. However, if doctors have tools at their disposal, such as numerical models and simulations for analyzing patient-specific blood vessels, they could use them to decide particular treatment necessary so, when. For models, different mechani...

Intraoperative neurophysiologic monitoring (IONM), including somatosensory evoked potential (SEP), and transcranial electric motor (MEP), had been utilized during brain or spine surgery to identify neurologic deficits. But some deficits, such as abulia, could not be detected through routine IONM. MEP SEP might monitor non-motor sensory lesions surgery. We experienced a 72-year-old case with an ...

Patients: 601 patients (mean age 64 y, 57% men) who were conscious, had a computed tomography–confirmed spontaneous lobar ICH (volume 10 to 100 mL) ≤ 1 cm from the cortical surface of the brain, and presented ≤ 48 hours after ictus. Exclusion criteria included hemorrhage that was intraventricular, due to arteriovenous malformation confirmed by angiography or an aneurysm, secondary to tumor or t...

t rue saccular aneurysm is exceptional in coarctation of aorta in children. a 6-year-old girl with headache and systemic arterial hypertension referred to our center for cardiovascular evaluation. physical examination revealed high blood pressure and weak lower extremity pulses. two-dimensional and doppler echocardiography and angiography demonstrated a saccular aneurysm of the descending aorta...

Isolated abducens nerve paresis related to ruptured vertebral artery (VA) aneurysm is rare. It usually occurs bilaterally or ipsilaterally to the pathologic lesions. We report the case of a contralateral sixth nerve palsy following ruptured dissecting VA aneurysm. A 38-year-old man was admitted for the evaluation of a 6-day history of headache. Abnormalities were not seen on initial computed to...

Fusiform aneurysms on the basilar artery (BA) trunk are rare. The microsurgical management of these aneurysms is difficult because of their deep location, dense collection of vital cranial nerves, and perforating arteries to the brain stem. Endovascular treatment is relatively easier and safer compared with microsurgical treatment. Selective occlusion of the aneurysmal sac with preservation of ...

A 75-year-old man suffered acute subdural hematoma shortly after trivial head trauma. Thirteen hours after a trivial brow to the occipital region, caused by contact with a mat, he suddenly deteriorated to the level of a Glasgow Coma Scale score of 6. Computed tomography demonstrated an acute subdural hematoma on the left and angiography revealed an aneurysm of the distal middle cerebral artery....

Computer-based simulations are essential for clarifying the hemodynamics of brain aneurysms. Since cerebrovascular disease is often fatal, it is strongly desirable to predict its progression. While previous studies have clarified the initiation mechanism of aneurysms, their growth mechanism remains unclear. Consequently, it is difficult to develop a diagnostic system for predicting aneurysm rup...
