CNS HEMORRHAGE Flashcards
most common type of cns hmg
intracranial
most common reason of ich
hypertension
other etiologies
arteriovenous malformations (AVMs) and cocaine use in younger patients and amyloid angiopathy in the elderly, are often responsible.
best outcome predictor
size of the haematoma and size greater than 60 cc has a 30 day mortality of over 30 %
pathogenesis of neurological damage
haematoma expansion inthe first 24 hours followed by edems on 3-7 days
most common sites of ich
Most common sites of hypertensive ICH are the basal ganglia, deep cerebellum, and pons.
blood pressure management in ich
The mean arterial pressure (MAP) should be kept between 100 and 120 mmHg, to maintain brain perfusion without increasing the edema surrounding the hematoma. Agents such as beta-blockers, calcium channel blockers, and angiotensin-converting enzyme (ACE) inhibitors are generally considered safe, since they do not increase ICP, while nitrates and sodium nitroprusside are generally avoided since they can suddenly increase ICP.
role of neurosurgical intervention
surgery is likely to be of minimal benefit as shown inthe recent STITCH trial.
the indicators of surgery are
1.infratentorial i.e posterior fossa or temporal lobe hmg greater than 3 cm
2. ich causing hydrocephalus or brainstem compression
the role of early surgery in casr of a superficial supratentorial hmg is controversial
post ich anticoagulation management
In the presence of a clear indication for anticoagulation (e.g., mechanical
heart valve) or antiplatelet therapy (e.g., coronary artery stents), it is reasonable to
restart anticoagulation in nonlobar ICH in 2 to 4 weeks and antiplatelet therapy in all
ICH 1 to 2 weeks after documentation of cessation of bleeding.
most common site 0of intra cranial aneurysm
at the bifurcation of arteries of circle of willis mostly in the anterior circulation
the anterior cerebral artery
internal carotid artery
which part of the aneurysm sac is prone to rupture
the dome
in which of the following focal neurological signs are more common SAH or ICH
ICH
incidence and mortality of rebleed
The incidence of rerupture of an untreated aneurysm is about 30%, mostly occurring in the first 48 hours after the initial event and having a 60% mortalitity
target map for sah
100 to 120
