Aneurysmal Subarachnoid Hemorrhage and Vasospasm.

Area of Science:

• Neurosurgery
• Neurology
• Critical Care Medicine

Background:

• Aneurysmal subarachnoid hemorrhage (aSAH) is a life-threatening neurological emergency with high morbidity and mortality.
• Despite advances, patients with aSAH face significant risks, including cerebral vasospasm and delayed cerebral ischemia.
• Neurosurgical and endovascular interventions have evolved to manage ruptured aneurysms.

Purpose of the Study:

• To review the diagnosis and treatment of aSAH.
• To discuss the management of associated vasospasm and delayed cerebral ischemia.
• To explore concurrent medical considerations and future research directions in neuroinflammatory vasospasm.

Main Methods:

• Literature review of neurosurgical and endovascular interventions for aSAH.
• Discussion of diagnostic modalities for aSAH, vasospasm, and ischemia.
• Synthesis of current medical management strategies and future research avenues.

Main Results:

• Improved mortality rates for aSAH due to advancements in surgical and endovascular techniques.
• Identification of external ventricular drain placement, aneurysm clipping, and endovascular coiling as key interventions.
• Recognition of cerebral vasospasm and delayed cerebral ischemia as critical complications.

Conclusions:

• Effective management of aSAH relies on timely diagnosis and multimodal treatment strategies.
• Addressing complications like vasospasm and ischemia is crucial for improving patient outcomes.
• Further research into neuroinflammatory mechanisms of vasospasm is warranted to enhance therapeutic approaches.
