🃏 1️⃣ High-Yield Flashcards

What is thrombophlebitis?

Inflammation of a vein associated with thrombus formation.

What is phlebothrombosis?

Formation of a thrombus in a vein without primary inflammation, commonly in deep veins.

Which has more prominent redness, warmth, and tenderness: thrombophlebitis or phlebothrombosis?

Thrombophlebitis.

Which venous thrombus has greater risk of pulmonary embolism?

Deep phlebothrombosis / deep venous thrombosis.

What is the main mechanism of varicose veins?

Venous valve incompetence → reflux → venous hypertension → superficial vein dilatation.

Name important risk factors for varicose veins.

Prolonged standing, pregnancy, obesity, age, family history, and previous DVT.

Why do varicose vein symptoms worsen on standing?

Standing increases venous pressure and worsens venous reflux.

What causes brown pigmentation around the ankle in chronic venous disease?

RBC breakdown with hemosiderin deposition.

Where is a venous ulcer classically found?

Near the medial malleolus.

Enlist common benign vascular tumors.

Hemangioma, pyogenic granuloma, lymphangioma, and glomus tumor.

Enlist important malignant vascular tumors.

Angiosarcoma, Kaposi sarcoma, epithelioid hemangioendothelioma, and leiomyosarcoma of large veins.

Why is the term pyogenic granuloma misleading?

It is not a true pus-forming infection and not a true granuloma; it is a vascular proliferation.

What is the key mechanism of cardiac glycoside toxicity?

Inhibition of Na⁺/K⁺-ATPase.

What classic symptoms suggest cardiac glycoside toxicity?

Vomiting, visual halos, bradycardia, AV block, irregular pulse, and collapse.

Which plant causes digoxin-like cardiotoxicity?

Oleander.

What is the specific antidote for severe digoxin toxicity?

Digoxin-specific Fab antibody fragments.

What cardiac effects are caused by cocaine and Ice?

Tachycardia, hypertension, coronary vasospasm, arrhythmia, hyperthermia, and sudden death.

What is informed consent before an invasive procedure?

Voluntary agreement after understanding procedure, risks, benefits, alternatives, and right to refuse.

📋 3️⃣ Memory Tables

Table 1: Thrombophlebitis vs Phlebothrombosis

Feature	Thrombophlebitis	Phlebothrombosis
Main process	Inflammation + thrombus	Thrombus without primary inflammation
Common site	Superficial veins	Deep veins
Local signs	Pain, redness, warmth	Minimal redness, may be silent
Palpable cord	Common	Usually absent
Main danger	Local inflammation	Pulmonary embolism

Table 2: Cardiac Glycosides/Oleander vs Cocaine/Ice

Feature	Cardiac Glycosides / Oleander	Cocaine / Ice
Main mechanism	Na⁺/K⁺-ATPase inhibition	Sympathetic overactivity
Pulse clue	Bradycardia / AV block	Tachycardia
BP clue	Hypotension/collapse may occur	Hypertension common
Key symptoms	Vomiting, visual halos, irregular pulse	Agitation, chest pain, hyperthermia
Major danger	Fatal arrhythmia	MI, arrhythmia, sudden death
Treatment clue	ECG monitoring ± Fab for severe digoxin	Benzodiazepines, cooling, ECG monitoring

⚡ 4️⃣ Rapid Revision Points

Must Remember

• Thrombophlebitis = inflamed vein + thrombus.
• Phlebothrombosis = deep thrombus with less inflammation and higher embolism risk.
• Varicose veins are mainly due to venous valve incompetence.
• Venous hypertension causes edema, eczema, pigmentation, and ulceration.
• Medial malleolus is the classic site of venous ulcer.
• Hemangioma and pyogenic granuloma are benign vascular tumors.
• Angiosarcoma is a malignant endothelial tumor.
• Cardiac glycosides and Oleander cause digoxin-like toxicity.
• Digoxin toxicity causes vomiting, visual halos, bradyarrhythmia, and AV block.
• Cocaine and Ice cause sympathetic storm, coronary vasospasm, arrhythmia, and sudden death.
• Suspected poison material must be preserved, labeled, sealed, and documented.
• Informed consent is explanation + understanding + voluntary agreement, not just a signature.

🩺 5️⃣ Clinical Memory Hooks

Clinical Hook 1

Painful red superficial cord on leg → Thrombophlebitis
Inflamed superficial vein with thrombus formation.

Clinical Hook 2

Bedridden patient + deep calf swelling + minimal redness → Phlebothrombosis / DVT
Venous stasis and hypercoagulability with embolism risk.

Clinical Hook 3

Tortuous leg veins worse on standing → Varicose veins
Valve incompetence causes reflux and venous hypertension.

Clinical Hook 4

Vomiting + visual halos + bradycardia → Cardiac glycoside toxicity
Think Na⁺/K⁺-ATPase inhibition.

Clinical Hook 5

Chest pain + hypertension + tachycardia after cocaine/Ice → Stimulant cardiotoxicity
Catecholamine excess causes vasospasm, ischemia, and arrhythmia.
