Chronic Venous Insufficiency Indian Medical PG Practice Questions and MCQs
Question 1: Deep vein thrombosis post-operatively is diagnosed by:
- A. Clinically
- B. Ascending venography
- C. USG (Correct Answer)
- D. X-ray
Explanation: ***USG*** - **Duplex ultrasonography** is the preferred and most common imaging modality for diagnosing deep vein thrombosis (DVT) due to its non-invasive nature, accessibility, and high accuracy. - It visualizes the **vein lumen** and assesses **compressibility**, a key diagnostic feature for DVT. *Clinically* - Clinical diagnosis of DVT is unreliable, as symptoms like **leg swelling, pain, and tenderness** are non-specific and can be caused by other conditions. - While clinical suspicion can warrant further investigation, it is **insufficient for definitive diagnosis**. *Ascending venography* - **Ascending venography** was once considered the gold standard but is now rarely used due to its invasive nature, use of ionizing radiation, and potential complications. - It involves injecting **radiocontrast dye** into a foot vein and taking X-rays, making it less practical for routine use compared to ultrasound. *X-ray* - **X-rays do not directly visualize veins** or blood clots and are therefore not useful for diagnosing DVT. - They may be used to rule out other causes of leg pain or swelling, such as **bone fractures** or **arthritis**, but offer no diagnostic value for DVT itself.
Question 2: Which of the following is not a direct cause of varicose veins?
- A. Superficial venous thrombosis (Correct Answer)
- B. Deep venous thrombosis
- C. Pregnancy
- D. Arteriovenous fistula
Explanation: ***Superficial venous thrombosis*** - While *superficial venous thrombosis* is a condition affecting veins, it is typically a **complication** or a co-occurring event with varicose veins, rather than a direct cause of their initial formation. - Varicose veins are primarily caused by **venous insufficiency** due to faulty valves, leading to blood pooling and vessel distension. *Arteriovenous fistula* - An *arteriovenous fistula* creates an abnormal connection between an **artery and a vein**, leading to high pressure flow directly into the venous system. - This **increased venous pressure and flow** can overwhelm venous valves and dilate veins, directly causing varicose veins. *Deep venous thrombosis* - *Deep venous thrombosis* can damage venous valves in the deep venous system, leading to **post-thrombotic syndrome** which includes chronic venous insufficiency and the formation of varicose veins due to reflux. - The resulting **venous hypertension** and impaired flow in the deep system can cause superficial veins to dilate and become tortuous. *Pregnancy* - *Pregnancy* is a common cause of varicose veins due to several factors, including **increased circulating blood volume** and the physical pressure of the growing uterus on the inferior vena cava. - Hormonal changes during pregnancy, particularly increased **progesterone**, also contribute by relaxing venous walls, further predisposing to varicosity.
Question 3: Falsely elevated ankle brachial index is used for evaluation of?
- A. Deep vein thrombosis
- B. Acute limb ischemia
- C. Calcified vessels (Correct Answer)
- D. Chronic venous insufficiency
Explanation: A falsely elevated **ankle-brachial index (ABI)**, often >1.3, indicates that the **ankle arteries are non-compressible** due to calcification [1]. This calcification is common in conditions like **diabetes** and **end-stage renal disease**, where the vessels become stiff and resist compression, leading to inaccurate pressure readings [1].
Question 4: CEAP score indicates-
- A. Atrial disorders
- B. Venous disorder (Correct Answer)
- C. Trauma disorder
- D. Neurological disorder
Explanation: ***Venous disorder*** - The **CEAP classification** is a widely recognized system used to categorize and describe chronic venous disorders. The acronym stands for **Clinical, Etiological, Anatomical, and Pathophysiological** factors. - It provides a standardized framework for clinicians to classify the severity and characteristics of **venous disease**, ranging from spider veins to active ulcers. *Atrial disorders* - **Atrial disorders** refer to conditions affecting the atria of the heart, such as **atrial fibrillation** or **atrial flutter**. - These are cardiovascular conditions distinct from venous disorders, which involve the veins (blood vessels returning blood to the heart). *Neurological disorder* - A **neurological disorder** is a condition affecting the **nervous system**, including the brain, spinal cord, and nerves. - The CEAP classification is specifically designed for vascular conditions and has no direct relevance to neurological diseases. *Trauma disorder* - A **trauma disorder** is a condition resulting from a **physically or psychologically traumatic event**. - While trauma can sometimes lead to venous issues (e.g., deep vein thrombosis from immobilization), the CEAP score itself is a classification system for chronic venous disease, not for traumatic conditions in general.
Question 5: A 55-year-old male, known smoker, complains of calf pain while walking. He experiences calf pain while walking but can continue walking with effort. Which grade of claudication does this patient fall under?
- A. Grade I (Mild claudication)
- B. Grade II (Moderate claudication) (Correct Answer)
- C. Grade III (Severe claudication)
- D. Grade IV (Ischemic rest pain)
Explanation: ***Grade II (Moderate claudication)*** - **Grade II claudication** is characterized by **intermittent claudication** where the patient experiences pain while walking but can **continue walking with effort**. - This level of claudication reflects a moderate degree of peripheral arterial disease, where blood flow is sufficiently compromised to cause pain with exertion but not severe enough to force immediate cessation of activity. - The patient in this scenario can continue ambulation despite discomfort, which is the defining feature of this grade. *Grade I (Mild claudication)* - **Grade I claudication** involves discomfort or pain that the patient can **tolerate without significantly altering their gait or pace**. - In this stage, the pain is minimal, and the patient may perceive it as a dull ache or mild fatigue rather than true pain. - Walking can continue without significant effort or limitation. *Grade III (Severe claudication)* - **Grade III claudication** is marked by pain that is **severe enough to stop the patient from walking within a short distance** (typically less than 200 meters). - The pain forces the patient to rest and recover before they can resume walking. - This represents significant functional limitation in daily activities. *Grade IV (Ischemic rest pain)* - **Grade IV**, also known as **critical limb ischemia**, involves **pain even at rest**, especially in the feet or toes, often worsening at night when the limb is elevated. - This stage indicates severe arterial obstruction and is frequently associated with **ulcers, non-healing wounds, or gangrene**. - This represents advanced peripheral arterial disease requiring urgent intervention. **Note:** This grading system is a simplified clinical classification. The standard medical classifications for peripheral arterial disease are the **Fontaine classification** (Stages I-IV) and **Rutherford classification** (Categories 0-6).
Question 6: What is the most effective management strategy for hemarthrosis?
- A. Immobilization with a P.O.P. cast
- B. Application of a compression bandage
- C. Needle aspiration to remove excess blood (Correct Answer)
- D. All of the options
Explanation: ***Needle aspiration to remove excess blood*** - **Aspirating the blood** from the joint effectively reduces intra-articular pressure, pain, and inflammation. - This procedure also helps prevent **synovial hypertrophy** and **cartilage damage** caused by the presence of blood in the joint. *Application of a compression bandage* - While helpful for reducing swelling and providing support, a **compression bandage alone** does not remove the accumulated blood. - It may alleviate some discomfort but does not address the underlying issue of **intra-articular blood accumulation**. *Immobilization with a P.O.P. cast* - **Immobilization** can help rest the joint and reduce pain, but it does not remove the blood from the joint space. - Prolonged immobilization can lead to **joint stiffness** and **muscle atrophy**, which are undesirable outcomes. *All of the options* - While compression and immobilization can be supportive measures, they are not the **most effective primary strategy** for managing hemarthrosis. - The direct removal of blood via **aspiration** is crucial for alleviating pressure and preventing long-term joint damage.
Question 7: Statement 1 - A 59-year-old patient presents with flaccid bullae. Histopathology shows a suprabasal acantholytic split. Statement 2 - The row of tombstones appearance is diagnostic of Pemphigus vulgaris.
- A. Statements 1 & 2 are correct, 2 is not explaining 1 (Correct Answer)
- B. Statements 1 and 2 are correct and 2 is the correct explanation for 1
- C. Statements 1 and 2 are incorrect
- D. Statement 1 is incorrect
Explanation: ***Correct: Statements 1 & 2 are correct, 2 is not explaining 1*** **Analysis of Statement 1:** - A 59-year-old patient with **flaccid bullae** and **suprabasal acantholytic split** on histopathology is the classic presentation of **Pemphigus vulgaris** - The flaccid (easily ruptured) nature of bullae distinguishes it from tense bullae seen in bullous pemphigoid - The suprabasal location of the split (just above the basal layer) with acantholysis (loss of cell-to-cell adhesion) is pathognomonic - **Statement 1 is CORRECT** ✓ **Analysis of Statement 2:** - The **"row of tombstones" or "tombstone appearance"** is indeed a diagnostic histopathological feature of Pemphigus vulgaris - This appearance results from basal keratinocytes remaining attached to the basement membrane while suprabasal cells separate due to acantholysis - The intact basal cells standing upright resemble a row of tombstones - **Statement 2 is CORRECT** ✓ **Does Statement 2 explain Statement 1?** - Statement 2 describes a **histopathological appearance** (tombstone pattern) that is a **consequence** of the suprabasal split - However, it does NOT explain the **underlying cause** of the flaccid bullae or the suprabasal split - The true explanation involves **IgG autoantibodies against desmoglein 3 (and desmoglein 1)**, which attack intercellular adhesion structures (desmosomes), causing **acantholysis** - Therefore, **Statement 2 does NOT explain Statement 1** ✗ *Incorrect: Statement 2 is the correct explanation for Statement 1* - While both statements describe features of Pemphigus vulgaris, the tombstone appearance is a descriptive finding, not an explanatory mechanism *Incorrect: Statements 1 and 2 are incorrect* - Both statements are medically accurate descriptions of Pemphigus vulgaris features *Incorrect: Statement 1 is incorrect* - Statement 1 correctly describes the cardinal clinical and histopathological features of Pemphigus vulgaris
Question 8: Sclerotherapy for varicose veins is contraindicated in the following condition:
- A. Deep vein Thrombosis (Correct Answer)
- B. Varicose ulcers
- C. Pigmentation Over limb
- D. Hemorrhoids
Explanation: ***Deep vein Thrombosis*** - **Sclerotherapy** involves injecting a solution that irritates and scars the vein, causing it to close. If **deep vein thrombosis (DVT)** is present, this procedure could dislodge a **thrombus**, leading to a potentially fatal **pulmonary embolism**. - Additionally, DVT indicates a compromised deep venous system, and treating superficial veins with sclerotherapy when the deep system is inadequate can lead to **worsened venous insufficiency** and complications. *Varicose ulcers* - **Varicose ulcers** are often a complication of **venous insufficiency**, and **sclerotherapy** can sometimes be used cautiously, in conjunction with compression therapy, to treat the underlying insufficient veins that contribute to ulcer formation. - While it's not a universal treatment for all ulcers, the presence of an ulcer itself is not an absolute **contraindication** if the underlying venous pathology can be safely addressed. *Pigmentation Over limb* - **Pigmentation over the limb** (often **hyperpigmentation**) is a common sign of **chronic venous insufficiency** and a cosmetic concern associated with **varicose veins**. - It is not a contraindication to **sclerotherapy**; in fact, successful treatment of the underlying varicose veins can sometimes lead to an improvement in or prevention of further pigmentation. *Hemorrhoids* - **Hemorrhoids** are essentially **varicose veins** of the **anorectal region**. While **sclerotherapy** can be used to treat hemorrhoids (a procedure called sclerotherapy for hemorrhoids), they are distinct from **lower limb varicose veins**. - The presence of hemorrhoids does not contraindicate **sclerotherapy** for leg varicose veins, as they are separate vascular systems and pathologies.
Question 9: A policeman of 45 years presented with Lipodermatosclerosis over lower medial aspect of left leg, along with a healed venous ulcer. As per the CEAP (Clinical-etiology-anatomy-pathophysiology) classification his clinical classification will be:
- A. C5 (Correct Answer)
- B. C4b
- C. C6
- D. C4a
Explanation: **C5 (healed venous ulcer)** - The CEAP classification for **C5** indicates the presence of a **healed venous ulcer**, which matches the patient's presentation of a healed ulcer. - The associated **lipodermatosclerosis** is a skin change often preceding or accompanying venous ulcers. *C4b (lipodermatosclerosis, atrophie blanche)* - **C4b** represents **lipodermatosclerosis** and **atrophie blanche**, which are skin changes due to chronic venous insufficiency. - While the patient has lipodermatosclerosis, the presence of a *healed ulcer* further elevates the classification to C5, as it signifies a more advanced stage of venous disease. *C6 (active venous ulcer)* - **C6** denotes an **active, open venous ulcer**. - The patient's ulcer is explicitly stated as "healed," making C6 an incorrect classification. *C4a (pigmentation or eczema)* - **C4a** refers to skin changes such as **pigmentation** or **venous eczema**. - While the patient might have some pigmentation associated with lipodermatosclerosis, the presence of a *healed ulcer* indicates a more severe clinical stage than C4a.
Question 10: The commonest site for venous ulcer is?
- A. Instep of foot
- B. Lower 1/3 leg and ankle (Correct Answer)
- C. Lower 2/3 of leg
- D. Middle 1/3 of leg
Explanation: **Lower 1/3 leg and ankle** - Venous ulcers most commonly occur in the "gaiter area," which refers to the **lower third of the leg** and around the **medial malleolus (ankle)**. This region is subject to the highest venous pressure. - The elevated venous pressure in the lower leg, due to venous insufficiency, leads to extravasation of fluid and cells, causing tissue damage and ulcer formation. *Instep of foot* - Ulcers on the instep of the foot are less common for typical venous ulcers, though they can occur with various etiologies. - This area is more commonly associated with neuropathic ulcers in diabetic patients or pressure ulcers. *Lower 2/3 of leg* - While the lower leg is generally affected, specifying the lower **two-thirds** is less precise than the "lower 1/3 and ankle" for the most frequent location of venous ulcers. - The pathophysiology of venous insufficiency disproportionately affects the most dependent part of the lower limb. *Middle 1/3 of leg* - The middle third of the leg is less frequently the primary site for venous ulcers compared to the ankle region. - Ulcers in this area might suggest a different etiology or advanced, widespread venous disease.
