Disease Name Confirmation
Arterial embolism and thrombosis (Arterial embolism and thrombosis) — This is a medically valid name. It includes a group of diseases in which blood flow is blocked by an embolus or thrombus arising in an artery, leading to tissue ischemia and necrosis.
1) Disease Description (Causes and Pathophysiology, Main Symptoms)
- Causes and pathophysiology
- Embolism: A thrombus that has broken away from the heart (mainly a thrombus in the left atrium, e.g., atrial fibrillation) or a large blood vessel (or an atherosclerotic plaque fragment or other embolic material) becomes lodged in a peripheral artery and acutely blocks blood flow.
- Arterial thrombosis: A thrombus forms locally due to damage to the arterial wall, rupture of an atherosclerotic plaque, or other causes, blocking the artery (chronic ischemia involves progressive arterial occlusion).
- As a result, the supply of blood, oxygen, and nutrients to the affected tissue is blocked, which can progress to acute pain, sensory abnormalities, muscle weakness, and necrosis. Serious functional impairment occurs when organs such as the brain, heart, or intestines are damaged.
- Main symptoms
- Limbs (especially the distal parts): Severe pain, coldness, pallor, absent pulse (pulselessness), tingling/decreased sensation, motor paralysis, mottled or bluish-purple skin discoloration, and gangrene
- Brain (embolic cerebral infarction): Sudden hemiplegia, language impairment (aphasia), altered consciousness, etc.
- Organs (intestines, kidneys, etc.): Acute abdominal pain, vomiting, decreased organ function, etc.
- Symptoms vary depending on the location and extent of the embolus/thrombus and the speed of onset (acute vs. chronic)
2) Treatment Methods and Precautions
- Acute situations (e.g., acute limb ischemia)
- Immediate anticoagulant therapy (intravenous heparin; administered immediately to prevent thrombus progression)
- Prompt referral to vascular surgery and vascular intervention: embolectomy (surgical embolectomy, thrombus aspiration/thrombectomy), catheter-directed thrombolysis (localized) when reperfusion is possible, balloon angioplasty or stenting, etc.
- Pain control, prevention of infection and gangrene, and excision in cases of necrosis (amputation in the worst case)
- Chronic management and prevention of recurrence
- Correct the cause: Long-term anticoagulation (oral anticoagulants) when heart disease such as atrial fibrillation is the cause
- DOACs (direct oral anticoagulants) are generally recommended first (warfarin is recommended in some cases, such as mechanical heart valves and severe mitral stenosis)
- INR monitoring is necessary when taking warfarin
- Antiplatelet agents (when concomitant cardiovascular atherosclerotic disease is present), active management of risk factors such as hyperlipidemia, hypertension, and diabetes, smoking cessation, and weight and exercise management
- Correct the cause: Long-term anticoagulation (oral anticoagulants) when heart disease such as atrial fibrillation is the cause
- Medications
- Anticoagulants: Heparin (acute treatment), warfarin, and DOACs (such as rivaroxaban and apixaban)
- Antiplatelet agents: Aspirin and clopidogrel (when atherosclerosis or peripheral artery disease is also present)
- Thrombolytics: Used for acute embolism after considering the indications and bleeding risk (systemic or localized)
- Risk of complications and precautions (including self-management)
- Anticoagulant and antiplatelet therapy increases the risk of bleeding (including gastrointestinal bleeding and intracranial hemorrhage) → Contact a doctor immediately if signs of bleeding occur, such as bloody urine, bloody stool, excessive bruising, or persistent nosebleeds
- Before dental or surgical procedures, whether to stop anticoagulants must be adjusted in advance in consultation with a doctor
- Medication selection and monitoring are necessary in people with a history of peptic ulcers or bleeding disorders
- Rapid reperfusion is decisive for the prognosis (limb preservation and organ function) → If this condition is suspected, visiting an emergency room is recommended
3) Checklist Before an Outpatient Visit (Including Items to Bring and Sample Questions)
- Items to bring
- A list of currently used medications (medication names, doses, and administration times), including anticoagulants, antiplatelet agents, vitamin supplements, and herbs
- Past medical history (heart disease, peptic ulcers, history of bleeding, surgical history) and allergy information
- Copies or records of recent test results (electrocardiogram, echocardiogram, blood tests, INR, etc.)
- A record of when symptoms began and how they have progressed (when they started and how they have changed)
- Photos of the symptomatic area (if peripheral necrosis is suspected)
- Whether you have eaten recently (in case surgery is needed), identification card, and insurance card
- Items to check before the outpatient visit
- Whether you are currently taking anticoagulants and your most recent INR (if taking warfarin)
- Bleeding risk factors (peptic ulcers, history of cerebral hemorrhage, etc.)
- Kidney function (necessary to determine the DOAC dose)
- Information to tell the doctor first during the outpatient visit
- Whether there is sudden limb pain, numbness, or loss of pulse, and whether you have recently been diagnosed with atrial fibrillation
4) Examples of General Questions to Ask the Doctor
- What are the main side effects of this medication (e.g., warfarin, a DOAC, or aspirin)? How high is the risk of bleeding?
- How long do I need to take anticoagulants?
- What lifestyle guidelines should I follow to reduce the risk of bleeding?
- If an emergency occurs (skin color changes, severe pain, or altered consciousness), how should I respond immediately?
- How does the choice of medication change if I have an existing condition such as a peptic ulcer or kidney disease?
5) Examples of Disease-Specific Questions (1–2)
- In my case, if the embolism is caused by atrial fibrillation based on my electrocardiogram/echocardiogram results, is there a specific reason I should take warfarin instead of a DOAC (e.g., a mechanical heart valve or severe mitral stenosis)?
- In my current situation with symptoms such as acute limb ischemia, how do you determine whether immediate thrombectomy (embolectomy) or catheter-directed thrombolysis is recommended and when emergency surgery is necessary?
Additional Guidance
- If you have acute symptoms suggestive of this condition (sudden limb pain, numbness, or loss of pulse; sudden hemiplegia or language impairment, etc.), you should immediately visit an emergency room and receive specialized care from vascular surgery, neurology, or another relevant department. Early reperfusion determines the prognosis.
