Hemorrhagic Stroke

Aneurysm treatment at UC San Diego Health

What Is Hemorrhagic Stroke?

Hemorrhagic stroke occurs when a weakened blood vessel bursts inside the brain. While they only account for 13 percent of stroke cases, they are responsible for almost 30 percent of all stroke deaths. 

UC San Diego Health saves lives every day with advanced open cranial and minimally invasive neurovascular treatment for conditions causing hemorrhagic stroke. Read about our stroke center’s quality and outcomes.

Types of Hemorrhagic Stroke

There are two types of hemorrhagic stroke:

  1. Intracerebral
  2. Subarachnoid

Intracerebral Hemorrhage

Intracerebral hemorrhage is the most common type of hemorrhagic stroke. It occurs when a blood vessel bursts and spills blood directly into brain tissue.

Symptoms typically occur suddenly and without warning, and may include partial or complete vision loss, severe headache, nausea, and/or numbess in arms, legs or face (often on just one side of the body).

A range of surgical and medical techniques may be used, depending on the cause and severity of the stroke. Surgery is used in cases where brain cell damage is imminent.

Subarachnoid Hemorrhage

Subarachnoid hemorrhage

A subarachnoid hemorrhage occurs when blood spills into the area surrounding brain tissue. A ruptured aneurysm is typically the cause.

Like an intracerebral hemorrhage, there are usually no warning signs. If the hemorrhage is due to an aneurysm, you may have a headache prior to the onset of more severe symptoms. Other symptoms include nausea, stiff neck, loss of consciousness, and an intense headache.

Our team will determine the source of bleeding, and repair either through clipping or embolization.

Causes of Hemorrhagic Stroke

Ruptured AVM

There are two categories of conditions that can cause hemorrhagic stroke, vascular lesions and underlying medical problems (such as high blood pressure).

High blood pressure is responsible for almost 60 percent of all hemorrhagic stroke cases. Fortunately, it is a controllable risk factor. Have your blood pressure checked regularly and speak to your doctor about your treatment options.

Vascular Lesions

Vascular lesions that can lead to stroke include:

Cerebral Aneurysm

Arteriovenous Malformations (AVM)

Dural Arteriovenous Fistula

Cavernous Malformations (Cavernomas)
