What is the management for a patient with multifocal ischemic cerebrovascular accident (CVA)?

Management of Multifocal Ischemic Cerebrovascular Accident (CVA)

Patients with multifocal ischemic CVA should receive immediate stabilization, rapid neuroimaging, and appropriate reperfusion therapy if eligible, followed by comprehensive stroke unit care including early rehabilitation and secondary prevention measures to reduce morbidity and mortality. 1, 2

Immediate Management

• Urgent evaluation should focus on airway, breathing, and circulation stabilization, especially in seriously ill or comatose patients 1
• Perform rapid neuroimaging (preferably CT) to confirm ischemic stroke and rule out hemorrhage before initiating treatment 1, 2
• Document precise time of symptom onset, as this determines eligibility for reperfusion therapies 2
• Assess stroke severity using a standardized scale such as the NIH Stroke Scale 2
• For patients presenting within 3 hours of symptom onset, intravenous recombinant tissue plasminogen activator (rtPA) at 0.9 mg/kg (maximum 90 mg) is strongly recommended if no contraindications exist 1

Acute Hospital Management

• Blood pressure management is critical - elevated blood pressure should be lowered cautiously in the acute phase 1
• For patients who received thrombolysis, maintain blood pressure below 180/105 mmHg for at least 24 hours 2
• Administer aspirin (160-300 mg) within 48 hours of stroke onset, but typically after 24 hours if thrombolysis was given 2
• Comprehensive stroke unit care is recommended for all patients with ischemic stroke 1
• Monitor for and aggressively treat complications including pneumonia, urinary tract infections, and deep vein thrombosis 1, 3

Management of Neurological Complications

• Monitor for cerebral edema, which typically peaks 3-5 days after stroke but can occur earlier with large infarctions 1
• Watch for seizures and hemorrhagic transformation, which are common neurological complications 1
• Implement early swallowing assessment before allowing oral intake to prevent aspiration pneumonia 1
• For patients with impaired swallowing, consider nasogastric or nasoduodenal tube feeding to maintain nutrition 1

Secondary Prevention

• Initiate statin therapy regardless of baseline cholesterol levels 2
• Start antihypertensive therapy after the acute phase (typically 24-48 hours post-stroke) 2
• For patients with atrial fibrillation, consider anticoagulation after ruling out hemorrhagic transformation 2, 4
• Address modifiable risk factors including smoking, diabetes, and hyperlipidemia 4, 5, 3
• Anticoagulant therapy significantly reduces the risk of recurrent stroke in patients with atrial fibrillation (OR: 0.39; 95% CI: 0.27-0.56) 4

Rehabilitation and Long-term Care

• Begin early mobilization when the patient is medically stable 2
• Initiate comprehensive rehabilitation addressing specific deficits: motor, sensory, language, and cognitive 2
• Implement measures to prevent subacute complications including aspiration, malnutrition, deep vein thrombosis, pulmonary embolism, and pressure sores 1
• For immobilized patients, use subcutaneous anticoagulants, intermittent external compression stockings, or aspirin to prevent deep vein thrombosis 1

Special Considerations for Multifocal Ischemic Stroke

• Multifocal ischemic strokes often indicate an embolic source (commonly cardiac) or systemic disease process 4
• Perform thorough cardiac evaluation including ECG monitoring for at least 24 hours to detect atrial fibrillation, which is a major risk factor for ischemic stroke (OR of 1.96 for men and 3.54 for women) 2, 4
• Consider advanced vascular imaging to identify potential sources of emboli 2
• Evaluate for hypercoagulable states, especially in younger patients or those without traditional risk factors 6, 3

Prognosis and Follow-up

• Multifocal ischemic strokes are associated with higher morbidity and mortality compared to single-territory strokes 3
• Provide education on stroke warning signs and risk factor modification 2
• Schedule regular follow-up to monitor neurological recovery and medication adherence 2
• Assess need for rehabilitation facility versus home with services based on functional status 2
