Types of hemorrhage in human brain 🧠 .

 

How many types of hemorrhage in brain?

        There are four types of hemorrhage.

(EDH) Epidural hemorrhage/ extra Dural hemorrhage.

(SDH) Subdural hematoma.

(SAH) Subarachnoid hemorrhage.

( ICH ) interacreanial hemorrhage,

Types of hemorrhage in brain

EDH :- an a epidural hemorrhage occurs when blood accumulates between the skull and dura mater, the thick membrane covering the brain. They typically occur when a skull fracture.

Extra Dural hemorrhage
Extra Dural hemorrhage


(SDH) Subdural hemorrhage :-

        A pool of blood between the brain and it’s outermost covering.

         A subdural hematoma is a type of bleed inside  head. More precisely, it is a type of bleed that occurs within the skull of head but out side the actual brain tissue. the brain has three membranes layers or coverings (called meninges) that layer between the bony skull and brain tissue.

(SAH) Subarachnoid hemorrhage:-

Bleeding in the space between the brain and tissue covering the brain.

           Subarachnoid hemorrhage is a type of stroke that can be caused by head injury. Many patients without head injury SAH is most commonly caused by a blood vessels aneurysm.

(ICH) Interacreanial hemorrhage:-

        Interacreanial hemorrhage refers to the accut blood in side the brain. Caused by hypertension or (high blood pressure).

Interacreanial hemorrhage
Intra creanial hemorrhage

The most common important symptoms.

          Head injury or trauma followed by loss of consciousness, a period of alertness, than rapid Deterioration back to unconsciousness.

  • Nausea or vomiting.
  • Confusion.
  • Dizziness.
  • Drowsiness or altered level of alertness.
  • Enlarged pupil in one eye.
  • Headache (severe).

Why should do CT SCAN of brain?

 

Why should do CT SCAN of brain?

       A CT scan of the brain perform to see interacreanial organs and stracture of skull 💀.  A CT scan perform cross section.

   Computed Tomography CT of the use special x-ray equipment to help asses head injury, severe headache, dizziness, and other symptoms of aneurysm, bleeding, stroke and brain tumor.

Precautions before doing CT scan :-

Tell your doctor if there a possibility female patient are pregnant.

If you exam need intravenous contrast you doctor may tell you not to eat or drink anything for a five hours before.

Leave jewelry  and wear loose and comfortable clothing.

What does show CT scan of the brain?

   Ct image show internal organs, like bone soft tissue and blood vessels provide greater detail than traditional x-ray. This is specially for soft tissue and blood vessels.

   CT scan provide more details information on head injury, stroke, brain tumor and other disease than regular x-ray.

What is three phase ct scan? Arterial phase, portal phase and Venus phase.

 

What is a three phase CT scan?

  Triple phase CT including an arterial phase, portal phase and Venus phase.

 

Why should do three phase scan?

Triple phase scan is mostly take for liver and biliary system.

Arterial:-  15-18 sec after bolus tracking

   Retoperitonial haemorrhage, in case of  removal of GB (gallbladder) in between liver and pancreas there is some infection spade, rupture of common hepatic artery (helium reason) may be rupture or narrowing. This are Post operative change’s, Aortic  obstruction

 

Portal phase (hepatic phase) biliary track:-  35-45 sec after bolus tracking

Portal phase for biliary tree
Portal phase for biliary tree

   Portal obstruction, liver crosses, hepatic ca metastatic change’s, cholanigo CA, Hepatic cyst, differencate between hepatic leassions.

 

Venus phase:-  90 sec after bolus tracking

Leassions, upper abdomen thrombosis, portal obstruction, renal mass, adenoma.

 The history of the CT (Computed Tomography) scan is a fascinating journey of innovation that revolutionized medical imaging. Here's a ...
