How do you grade an intraventricular hemorrhage?

How do you grade an intraventricular hemorrhage?

IVH is often described in four grades:

1. Grade 1. Bleeding occurs just in a small area of the ventricles.
2. Grade 2. Bleeding also occurs inside the ventricles.
3. Grade 3. Ventricles are enlarged by the blood.
4. Grade 4. Bleeding into the brain tissues around the ventricles.

What is a grade 1 IVH?

Grade 1: Bleeding is limited to the germinal matrix, a fragile area near the ventricles that contains many small capillaries. Grade 1 IVH is also called germinal matrix hemorrhage. Grade 2: Bleeding is found in the ventricles, but the ventricles remain the same size.

What is a grade 2 IVH?

There are four types of IVH. These are called “grades” and are based on the degree of bleeding. Grades 1 and 2 involve a smaller amount of bleeding. Most of the time, there are no long-term problems as a result of the bleeding. Grade 1 is also referred to as germinal matrix hemorrhage (GMH).

What is GMH IVH?

Germinal matrix hemorrhage and intraventricular hemorrhage (GMH-IVH; also referred to as intraventricular hemorrhage [IVH]) is an important cause of brain injury in the newborn, and in particular for preterm infants.

What causes IVH in preterm infants?

Two major factors that contribute to the development of GM/IVH are (1) loss of cerebral autoregulation and (2) abrupt alterations in cerebral blood flow and pressure. Healthy infants who were born prematurely have some ability to regulate cerebral blood flow through a process called autoregulation.

What causes IVH in newborns?

Problems from an early birth — such as low oxygen levels, changes in blood pressure, and breathing problems — can damage these fragile blood vessels, making them leak. Other reasons a baby might get an IVH include: a low birth weight (3 pounds or less) a difficult delivery.

Do all Grade 4 brain bleeds lead to cerebral palsy?

Grades 1 and 2 do not typically cause complications. Grades 3 and 4 are the most serious and may result in long-term brain injury or an intraventricular hemorrhage causing cerebral palsy.

What is a subependymal cyst?

Subependymal pseudocysts are cerebral cysts found in 5% of all neonates. When they are isolated and typical, they result from persistence of the germinal matrix, have a good prog- nosis and regress spontaneously within a few months.

What is the other term for germinal matrix?

Any haemorrhage in the preterm infant typically has its onset in the germinal matrix, also known as the ganglionic eminence, which is the source of future neuronal and glial cells in the immature brain [11,12].

What is neonatal IVH?

Intraventricular hemorrhage (IVH) of the newborn is bleeding into the fluid-filled areas, or ventricles, surrounded by the brain. The condition is most often seen in premature babies, and the smaller and more premature the infant, the higher the risk for IVH.

When is IVH diagnosed?

IVH is usually diagnosed during the first 72 hours after birth or later in the first week in very preterm infants. A newborn with IVH might be found to have subtle changes, either during the physical exam or in their behavior.

How is IVH diagnosed?

Signs of IVH include swelling of the head, abnormal blood pressure readings, seizures, major clinical deterioration with anemia, hypotension, and metabolic acidosis. A head ultrasound (HUS) will be performed to confirm the diagnosis.
