Subarachnoid Hemorrhage

Our experts in the Cerebrovascular Center at Mount Sinai specialize in evaluating and treating subarachnoid hemorrhage. Subarachnoid hemorrhage occurs when a blood vessel ruptures at the base of the brain. Blood fills up the subarachnoid space, an area between the brain and the thin tissues that cover it.

Causes for subarachnoid hemorrhage include brain aneurysms, arteriovenous malformations or AVMs, amyloid angiopathy, and head trauma.

Subarachnoid Hemorrhage Symptoms

A very severe headache that starts suddenly and is often located near the back of the head is the most common symptom of subarachnoid hemorrhage. Even if a patient is prone to headaches or migraines, this headache will feel very different from the normal pattern. It is often described as the "worst headache of your life."

Diagnosing a Subarachnoid Hemorrhage

Based on the patient's subarachnoid hemorrhage symptoms, the center’s physicians may perform the following tests:

Treatment Options for Subarachnoid Hemorrhage

Physicians in the Cerebrovascular Center treat subarachnoid hemorrhage by one or more of the following strategies:

  • Endovascular coiling of brain aneurysm – blocks blood flow into the aneurysm to prevent rupture

  • Mini-craniotomy and clip ligation of brain aneurysm to block it off from circulation

  • Endovascular embolization of the AVM, in which a special glue is injected to block abnormal vessels

  • Radiosurgery of the AVM, in which radiation is delivered directly

  • Surgical resection of the AVM

  • Minimally invasive “burrhole” removal of intracerebral hemorrhage

  • Balloon angioplasty for vasospasm

  • Ventriculostomy and ventriculoperitoneal shunt placement to prevent or relieve abnormal buildup of fluid in the brain

  • Craniotomy for decompression of brain edema (the excessive accumulation of fluid in the tissue)
