🧠 2️⃣ Mnemonics
Mnemonic Title: Aneurysm vs Dissection
Mnemonic Word: D-Split
Meaning:
- Dilatation = aneurysm
- SPLIT media = dissection
Mnemonic Title: Large Vessel Vasculitis
Mnemonic Word: GET TAKA
Meaning:
- Giant cell arteritis → Elderly → Temporal headache
- TAKAyasu → young woman → absent pulses
Mnemonic Title: GPA Pattern
Mnemonic Word: ELK
Meaning:
- ENT disease
- Lung lesions
- Kidney involvement
Mnemonic Title: Kawasaki Danger
Mnemonic Word: KAWA-COR
Meaning:
- KAWAsaki disease
- CORonary artery aneurysm risk
📋 3️⃣ Memory Tables
Table 1 — Aneurysm vs Aortic Dissection
| Feature | Aneurysm | Aortic Dissection |
|---|---|---|
| Basic lesion | Vessel dilatation | Blood splits media |
| Key mechanism | Wall weakness | Intimal tear |
| Common clue | Pulsatile mass | Tearing chest pain |
| Major danger | Rupture / emboli | Tamponade / ischemia |
| Exam trap | May contain mural thrombus | Not just dilatation |
Table 2 — Major Vasculitides
| Disease | Vessel size | Key clue | Major danger |
|---|---|---|---|
| Giant cell arteritis | Large | Elderly + headache | Blindness |
| Takayasu arteritis | Large | Young woman + absent pulses | Ischemia / HTN |
| Polyarteritis nodosa | Medium | Renal / mesenteric disease | Infarction |
| Kawasaki disease | Medium | Child + strawberry tongue | Coronary aneurysm |
| GPA / Wegener | Small-medium | ENT + lung + kidney | RPGN / lung disease |
| Thromboangiitis obliterans | Small-medium limb vessels | Young smoker + digital ischemia | Gangrene |
⚡ 4️⃣ Rapid Revision Points
Must Remember
• Aneurysm = abnormal dilatation due to vessel wall weakness.
• True aneurysm involves all three vessel wall layers.
• False aneurysm is blood outside the wall communicating with lumen.
• Abdominal aortic aneurysm is classically atherosclerotic and infrarenal.
• Aortic dissection begins with intimal tear and medial splitting.
• Hypertension is the key risk factor for dissection in older adults.
• Vasculitis means inflammation of blood vessel walls.
• Giant cell arteritis can cause irreversible blindness.
• Takayasu arteritis is pulseless disease of young women.
• PAN is medium-vessel necrotizing vasculitis with fibrinoid necrosis.
• Kawasaki disease threatens coronary arteries in children.
• GPA = c-ANCA with ENT–lung–kidney involvement.
• Thromboangiitis obliterans is smoking-related distal limb ischemia.
