Intracranial Hemorrhage Flashcards
large vessel or small vessel ischemic stroke
Large vessel: deficits in multiple symptoms. Requires large mechanism.
Small vessel: isolated motor or sensory deficit on one side of the body. Produce lacunar infarctions.
Mixed ischemia can occur (hypo perfusion)
deficits in multiple symptoms. Requires large mechanism.
Large vessel
isolated motor or sensory deficit on one side of the body. Produce lacunar infarctions.
Small vessel
Subdural Hem.
B/t dura and arachnoid
Ruptured bridging veins (slow bleed)- Concave (banana)
Elderly, etoh, trauma, shaken baby
Midline shift
Epidural Hem.
Occurs b/t the skull and dura- Convex (lemon shaped)
Rupture Middle Meningeal Artery (2o to fx)
CN III Palsy
Subarachnoid Hem.
Underneath the arachnoid layer
Rupture of aneurysm (berry)
WHOML
Bloody/yellow spinal tap
Intraparenchymal Hem.
Often caused by HTN
Occurs in basal ganglia
Common location: thalamus, basal ganglia, pons, cerebellum, cerebral lobes
NO treatment, fairly high mortality
s/s: decreced loc, vomiting, headache
Arteriovenous Malformation
abnormal connection between arteries and veins, bypassing the capillary system. This vascular anomaly is widely known because of its occurrence in the central nervous system, but can appear in any location. Although many AVMs are asymptomatic, they can cause intense pain or bleeding or lead to other serious medical problems.
