Cerebrovascular Disorders

Cerebrovascular disorders involve impaired cerebral blood flow due to vessel occlusion or rupture, leading to ischemia, infarction, or hemorrhage with rapid neurologic deterioration if untreated. These conditions are major causes of mortality and long-term disability, requiring immediate recognition, rapid imaging, and time-sensitive interventions. Nurses play critical roles in early stroke identification, airway protection, neurologic monitoring, complication prevention, and interdisciplinary coordination to improve outcomes and reduce permanent deficits.

1️⃣ Stroke Overview

🧠 Core Concepts & Pathophysiology

🔷 Cerebral blood flow interruption → ischemia, infarction, neuronal death within minutes

🔷 Ischemic (clot obstruction) vs hemorrhagic (vessel rupture bleeding into brain)

🔷 Penumbra (salvageable tissue) depends on rapid reperfusion and oxygenation

🔷 Atherosclerosis, emboli, hypertension major underlying mechanisms of injury

🔷 Brain highly sensitive to hypoxia → irreversible damage occurs quickly

🔷 CPP (cerebral perfusion pressure) ↓ when ICP ↑ leading to worsening injury

🔎 Clinical Findings & Risk Factors

🔷 Sudden unilateral weakness, facial droop, arm drift, leg weakness

🔷 Slurred or absent speech, aphasia, confusion, difficulty understanding commands

🔷 Vision loss, diplopia, neglect, dizziness, loss of coordination or balance

🔷 Severe headache sudden onset → suggests hemorrhagic stroke

🔷 Risk factors: HTN, diabetes, smoking, AF, obesity, hyperlipidemia

🔷 LOC changes early subtle confusion → late decreased responsiveness

💊 Diagnostics & Medical Management

🔷 CT scan STAT → differentiate ischemic vs hemorrhagic before treatment

🔷 MRI detects early ischemia but slower availability in emergencies

🔷 Labs: glucose, CBC, PT/INR, electrolytes → rule out mimics/bleeding risk

🔷 ECG to detect atrial fibrillation as embolic source

🔷 Oxygen therapy if SpO₂ <94% → prevent hypoxia-induced injury

🔷 BP control cautious → avoid rapid drop reducing cerebral perfusion

🩺 Nursing & Collaborative Priorities

🔷 Determine exact onset time → eligibility for thrombolytics critical decision

🔷 Maintain airway, suction PRN, aspiration precaution, NPO until swallow checked

🔷 Frequent neuro checks → LOC, pupils, motor strength, GCS trends

🔷 Elevate HOB 30°, keep head midline → promote venous drainage

🔷 Avoid excessive stimulation → prevent ICP spikes and agitation

🔷 Activate stroke team rapidly → multidisciplinary emergency response

2️⃣ Ischemic Stroke

🧠 Mechanisms & Progression

🔷 Thrombotic stroke → clot forms in narrowed cerebral artery gradually

🔷 Embolic stroke → clot travels from heart (AF) or carotid artery

🔷 Reduced blood flow → oxygen deprivation, infarction in affected region

🔷 Collateral circulation may delay symptom onset or reduce severity

🔷 Tissue damage depends on time → “time is brain” concept critical

🔷 Reperfusion restores function but may cause reperfusion injury

🔎 Signs, Symptoms & Risk Profile

🔷 Hemiparesis, hemiplegia → opposite side of brain lesion affected

🔷 Aphasia → Broca (expressive) or Wernicke (receptive) depending location

🔷 Dysphagia, drooling → cranial nerve involvement, aspiration risk ↑

🔷 Visual deficits → homonymous hemianopsia, neglect, diplopia

🔷 Risk factors: AF, carotid stenosis, smoking, sedentary lifestyle

🔷 No severe headache usually → differentiates from hemorrhagic stroke

💊 Diagnostics & Treatment

🔷 CT scan initially normal → confirms absence of hemorrhage

🔷 Alteplase (tPA) within 4.5 hours → dissolves clot restores perfusion

🔷 Antiplatelets: aspirin, clopidogrel → prevent further clot formation

🔷 Anticoagulants: heparin, warfarin, apixaban for AF-related emboli

🔷 Mechanical thrombectomy for large vessel occlusion within time window

🔷 Glucose control → avoid hyperglycemia worsening outcomes

🩺 Nursing & Monitoring

🔷 Monitor for bleeding post-tPA → gums, urine, IV sites, intracranial signs

🔷 Neuro checks q1h initially → detect worsening deficits early

🔷 Maintain bed rest initially → reduce metabolic demand and injury

🔷 Avoid invasive procedures post-tPA → bleeding risk ↑

🔷 Swallow assessment before oral intake → prevent aspiration pneumonia

🔷 Educate family on sudden deterioration signs and urgency

3️⃣ Hemorrhagic Stroke

🧠 Pathophysiology & Injury

🔷 Vessel rupture → blood accumulates increasing ICP rapidly

🔷 Intracerebral hemorrhage or subarachnoid hemorrhage (aneurysm rupture)

🔷 Mass effect → compression of brain structures, herniation risk

🔷 Decreased CPP → ischemia around hemorrhage site

🔷 Hypertension, aneurysm, AVM common causes

🔷 Blood breakdown products → inflammation, edema formation

🔎 Clinical Manifestations

🔷 Sudden severe headache “worst headache of life” classic sign

🔷 Projectile vomiting, nausea without warning

🔷 Rapid LOC decline → confusion, lethargy, coma progression

🔷 Unequal pupils, sluggish response → brainstem involvement

🔷 Seizures, neck stiffness → especially subarachnoid hemorrhage

🔷 Cushing triad: BP ↑, HR ↓, irregular respirations (late sign)

💊 Medical Management

🔷 Mannitol, hypertonic saline → reduce cerebral edema and ICP

🔷 Antihypertensives → labetalol, nicardipine control BP safely

🔷 Avoid anticoagulants → increases bleeding risk

🔷 ICU monitoring for unstable neurologic status

🩺 Nursing Considerations

🔷 Strict neuro monitoring → detect rapid deterioration early

🔷 CT angiography → identifies vessel occlusion, aneurysm, vascular abnormalities

🔷 Imaging determines eligibility → thrombolytics contraindicated in hemorrhage

🔷 Time-dependent imaging → delays worsen infarct size and neurologic outcome

🔷 Repeated imaging if worsening symptoms → detect hemorrhagic conversion or edema

🔎 Findings, Labs & Indicators

🔷 Hemorrhage appears hyperdense on CT → bright white area

🔷 Ischemic stroke may appear normal early → clinical correlation required

🔷 Labs: glucose (rule out hypoglycemia mimic), PT/INR, platelets before tPA

🔷 Elevated BP common → compensatory mechanism for cerebral perfusion

🔷 ECG → atrial fibrillation source of emboli

🔷 Electrolytes imbalance may worsen neurologic status

💊 Clinical Decision Points

🔷 No tPA until hemorrhage ruled out → strict protocol adherence

🔷 Large vessel occlusion → thrombectomy consideration

🔷 Contrast imaging caution → renal impairment risk
