| # | Front | Back | Hint |
|---|---|---|---|
| 1 | What is the hallmark clinical symptom of peripheral artery disease (PAD)? | Intermittent claudication—pain or cramping in the lower limbs during exertion that resolves with rest. | Think 'claudication' as classic PAD symptom. |
| 2 | Which diagnostic test is most commonly used to confirm PAD? | Ankle-Brachial Index (ABI) measurement—values less than 0.9 indicate PAD. | ABI compares systolic pressures; low ABI suggests arterial narrowing. |
| 3 | Name a common risk factor for developing peripheral artery disease. | Smoking, diabetes mellitus, hypertension, hyperlipidemia, or advanced age. | Think 'SMH'—smoking, metabolic, hypertensive factors. |
| 4 | What is the primary goal in the management of PAD? | Improve symptoms, prevent disease progression, and reduce cardiovascular risk through lifestyle modification, pharmacotherapy, and revascularization if needed. | Treat the patient holistically—vascular health and risk factors. |
| 5 | What is an abdominal aortic aneurysm (AAA)? | A localized dilation of the abdominal aorta exceeding 3 cm in diameter or more than 50% increase compared to normal size. | Think 'ballooning' of the aorta. |
| 6 | Which imaging modality is preferred for diagnosing an AAA? | Abdominal ultrasound—non-invasive, reliable, and cost-effective. | Ultrasound is the first-line screening tool. |
| 7 | When is surgical repair indicated for an AAA? | Typically when the aneurysm exceeds 5.5 cm in diameter or if it’s rapidly expanding or symptomatic. | Size matters—threshold of 5.5 cm. |
| 8 | What is the main complication of an untreated AAA? | Rupture, which can lead to life-threatening hemorrhage and death. | Rupture is the catastrophic risk. |
| 9 | What are the common risk factors for developing an aneurysm? | Atherosclerosis, smoking, hypertension, genetic factors (e.g., Marfan syndrome), and age. | Atherosclerosis and genetic predisposition are key. |
| 10 | Define venous thromboembolism (VTE). | A condition where a blood clot forms in a deep vein (deep vein thrombosis) and can embolize to the lungs causing pulmonary embolism. | VTE includes DVT and PE. |
| 11 | What are the common signs and symptoms of deep vein thrombosis (DVT)? | Swelling, pain, warmth, and redness in the affected limb, often the leg. | Remember 'swelling + pain' as DVT clues. |
| 12 | What is the most sensitive test for diagnosing DVT? | Venous Doppler ultrasound—detects absence of flow or compressibility of the vein. | Ultrasound is the go-to initial test. |
| 13 | Which clinical prediction rule helps estimate the probability of DVT? | The Wells Score—classifies risk as low, moderate, or high based on clinical features. | Wells helps decide on further testing. |
| 14 | What is the primary anticoagulant used for initial treatment of VTE? | Low molecular weight heparin (LMWH) or unfractionated heparin, followed by oral anticoagulants. | Start with heparin before oral agents. |
| 15 | What is the main goal of VTE management? | Prevent clot extension, embolization, and recurrent thrombosis, while minimizing bleeding risk. | Balance clot control with bleeding risk. |
| 16 | Name a common long-term complication of untreated or inadequately treated DVT. | Post-thrombotic syndrome—chronic pain, swelling, skin changes. | Think 'PT'—post-thrombotic. |
| 17 | What are the key differences between arterial and venous thrombosis? | Arterial thrombosis often involves platelets, is associated with atherosclerosis, and leads to ischemia; venous thrombosis involves fibrin and red blood cells, leading to congestion and embolism risk. | Arteries = platelets; veins = fibrin. |
| 18 | Which pharmacologic agent is often used to prevent recurrent VTE? | Warfarin or direct oral anticoagulants (DOACs) like rivaroxaban or apixaban. | Oral anticoagulants are mainstays for secondary prevention. |
| 19 | What lifestyle modification can help reduce the risk of vascular diseases? | Smoking cessation, regular exercise, healthy diet, weight control, and managing hypertension and diabetes. | Address modifiable risk factors. |
| 20 | Name one surgical or endovascular treatment option for aneurysms. | Endovascular aneurysm repair (EVAR) or open surgical repair—either aims to exclude the aneurysm from circulation. | Minimally invasive vs. open approach. |
