Subarachnoid Hemorrhage | Etiology, Pathophysiology, Clinical Features, Treatment, Complications

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this neuropathology lecture, Professor Zach Murphy delivers a high-yield and clinically focused overview of Subarachnoid Hemorrhage (SAH)—a neurologic emergency often caused by the rupture of cerebral aneurysms. This lecture breaks down the pathophysiology, clinical presentation, diagnostic approach, and critical management of this life-threatening condition. We begin by discussing the two major categories of SAH: traumatic and non-traumatic (spontaneous), with an emphasis on ruptured saccular (berry) aneurysms as the leading cause of spontaneous SAH. You’ll learn the classic presentation of a sudden, severe “thunderclap” headache, often described as the worst headache of a patient’s life, accompanied by nausea, vomiting, photophobia, neck stiffness, and potentially loss of consciousness. The lecture walks through the diagnostic algorithm, starting with a non-contrast CT scan, followed by lumbar puncture if the CT is non-diagnostic, highlighting the importance of identifying xanthochromia and elevated opening pressure. We also review the role of CT angiography in detecting aneurysms and guiding neurosurgical intervention. Management topics include blood pressure control, aneurysm repair via endovascular coiling or surgical clipping, and prevention of complications such as rebleeding, vasospasm, and hydrocephalus. The importance of nimodipine in reducing delayed cerebral ischemia and the need for close ICU-level monitoring are also emphasized. Enjoy the lecture and support us below!
