Nomogram for predicting delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage in the Chinese population
The incidence of stroke is high worldwide1 and is the leading cause of death in China presently.2,3 Subarachnoid hemorrhage caused by ruptured intracranial aneurysm is a subtype of severe stroke that occurs suddenly in seemingly healthy individuals with generally poor prognosis.4 Surgical clipping and endovascular coiling are effective treatment modalities for patients with aneurysmal subarachnoid hemorrhage (aSAH). Delayed cerebral ischemia (DCI) is a complication of aSAH, occurring in up to 30% of patients,5 and is an important cause of disability and death, often leading to deterioration of patients ’ condition or quality of life.

Increased Resting Energy Expenditure after Endovascular Coiling for Subarachnoid Hemorrhage
Appropriate nutritional care from the acute stage is essential for improved functional outcomes and reduced mortality in patients with subarachnoid hemorrhage (SAH). Although endovascular coiling is increasingly being used as an alternative to neurosurgical clipping and craniotomy for ruptured aneurysms, the resting energy expenditure (REE) of patients treated with this new technique has not been systemically evaluated.

Coil Embolization through Collateral Pathway for Ruptured Vertebral Artery Dissecting Aneurysm with Bilateral Vertebral Artery Occlusion
Intracranial vertebral artery dissecting aneurysm (VADA) is a well-known cause of subarachnoid hemorrhage (SAH). Endovascular treatment is now well established as an effective method for treating ruptured VADA, especially in the acute phase of SAH.1,2 Although stent technology has introduced a new strategy in the treatment of VADA, internal trapping of both the affected vertebral artery (VA) and the VADA using detachable coils is still the standard endovascular treatment for the acute phase of ruptured VADAs to prevent re-rupture.

A Propensity Score-Matched Comparison of Readmission Rates Associated With Microsurgical Clipping and Endovascular Treatment of Ruptured Intracranial Aneurysms
Background: In the treatment of aneurysmal subarachnoid hemorrhage (aSAH), microsurgical clipping, and endovascular therapy (EVT) with coiling are modalities for securing the ruptured aneurysm. Little data is available regarding associated readmission rates. We sought to determine whether readmission rates differed according to treatment modality for ruptured intracranial aneurysms. Methods: The Nationwide Readmissions Database (NRD) was used to identify adults who experienced aSAH and underwent clipping or EVT.

Effect of Neck Size on the Inflow Magnitude Evaluated on 4D Flow MRI in Unruptured Internal Carotid Artery Aneurysms
Endovascular coil embolization for cerebral aneurysms is widely performed to prevent hemorrhage or rebleeding, and it has low morbidity and mortality. However, recanalization which frequently arises during the follow-up period after coil embolization and occasionally leads to a catastrophic rupture remains a major limitation. A recanalization rate of 8.6 –27.4% has been reported in recent systematic reviews of studies that analyzed several thousands of cerebral aneurysms.1–3 A wide neck of aneurysms has been a key factor for recanalization.

Involvement of Cerebral Blood Flow on Neurological and Behavioral Functions after Subarachnoid Hemorrhage in Mice
Subarachnoid Hemorrhage (SAH) has a high mortality rate of up to 40%,1 and often causes severe neurological sequel in survivors. Spontaneous SAH is caused by a ruptured intracranial aneurysm. Despite the evolution of less invasive treatments for ruptured aneurysms, such as endovascular coil embolization, the mortality and morbidity rates of SAH still remain high.2 Thus, it is important to establish novel treatment strategies that focus on cognitive decline following SAH.

Contralateral Transradial Access for Coil Embolization of Distal Anterior Cerebral Artery Aneurysm Associated With a Steep Ipsilateral A1-A2 Angle
Distal anterior cerebral artery (DACA) aneurysms, also known as pericallosal artery aneurysms, have a high rupture rate. They are more frequently associated with multiple cerebral aneurysms than other supratentorial aneurysms.1-3 More than half of ruptured DACA aneurysms result in intracerebral hemorrhage.4 Consequently, patients with DACA aneurysms have a higher morbidity and mortality rate than those with other supratentorial aneurysms.1-3 As neurointerventional devices and techniques have developed and improved, endovascular treatment of DACA aneurysms has begun to garner higher success rates and better clinical and angiographic outcomes.
