Varicose Veins and Lymphatics Indian Medical PG Question 1: A mother brings her 5-year-old boy to see you as a General Physician. On examination, he has red eyes, dry, cracked lips and a rash on his hands and feet. He also has cervical lymphadenopathy. What is the most important investigation to rule out a serious complication of this condition?
- A. Blood pressure
- B. ECG
- C. Echocardiography (Correct Answer)
- D. Blood tests for autoantibodies
Varicose Veins and Lymphatics Explanation: ***Echocardiography***
- The constellation of symptoms (red eyes, cracked lips, rash on hands and feet, cervical lymphadenopathy in a 5-year-old) is highly suggestive of **Kawasaki disease**.
- **Coronary artery aneurysms** are the most serious complication of Kawasaki disease, making echocardiography crucial for early detection and management.
*Blood pressure*
- While important in any pediatric assessment, **blood pressure measurement** is not specific for diagnosing or monitoring the most critical complication of Kawasaki disease.
- Hypertensive or hypotensive episodes are not classic features and do not directly assess **coronary artery involvement**.
*ECG*
- An **ECG** can detect arrhythmias or signs of myocardial ischemia, which might occur with **coronary artery pathology**.
- However, it is less sensitive and specific than **echocardiography** for directly visualizing and quantifying **coronary artery aneurysms**.
*Blood tests for autoantibodies*
- Kawasaki disease is not an autoimmune condition primarily diagnosed by **autoantibodies**; it is a **vasculitis** of unknown etiology.
- Blood tests for autoantibodies would not be the most important investigation to rule out its most serious complication.
Varicose Veins and Lymphatics Indian Medical PG Question 2: Which of the following does not cause deep venous thrombosis (DVT)?
- A. Lower limb trauma
- B. Subungual hematoma (Correct Answer)
- C. Hip & pelvic surgeries
- D. Cushing's syndrome
Varicose Veins and Lymphatics Explanation: ***Subungual hematoma***
- A **subungual hematoma** is a collection of blood under the fingernail or toenail, usually caused by trauma.
- It is a localized injury that **does not affect systemic coagulation** or venous blood flow, thus not increasing DVT risk.
*Lower limb trauma*
- **Trauma to the lower limb**, especially involving fractures or significant soft tissue damage, can lead to **venous stasis** due to immobility and direct vessel injury [1].
- This immobility and vessel damage activate the **coagulation cascade**, significantly increasing the risk of DVT [1].
*Cushing's syndrome*
- **Cushing's syndrome** is characterized by **hypercortisolism**, which leads to a **hypercoagulable state**.
- **Elevated cortisol levels** increase circulating procoagulant factors and decrease fibrinolytic activity, predisposing patients to DVT.
*Hip & pelvic surgeries*
- **Major surgeries**, particularly those involving the **hip and pelvis**, frequently cause **endothelial injury**, blood stasis, and activate the coagulation system [1].
- Patients undergoing these procedures are at a **very high risk for DVT** due to prolonged immobility and surgical trauma [1].
Varicose Veins and Lymphatics Indian Medical PG Question 3: A 65M presents with worsening dyspnea and leg swelling. Physical examination reveals an elevated jugular venous pressure and bilateral lower extremity pitting edema. Most likely cause of his symptoms?
- A. Hypothyroidism
- B. Right-sided heart failure (Correct Answer)
- C. Chronic kidney disease
- D. Liver cirrhosis
Varicose Veins and Lymphatics Explanation: Right-sided heart failure
- **Elevated jugular venous pressure (JVP)** and **bilateral lower extremity pitting edema** are classic signs of fluid overload due to the inability of the right ventricle to effectively pump blood [2], [4].
- **Dyspnea** can occur due to congestion in the lungs (if left-sided failure is also present) or due to increased effort of breathing with significant fluid retention [1], [3].
*Hypothyroidism*
- While **hypothyroidism** can cause **non-pitting edema** (myxedema), it does not typically lead to elevated JVP.
- The dyspnea in hypothyroidism is often related to respiratory muscle weakness or pleural effusions, not primarily venous congestion.
*Chronic kidney disease*
- **Chronic kidney disease** can cause **fluid overload** and **edema**, but it typically presents with **pitting edema** and elevated JVP.
- However, the primary cause of the fluid retention in CKD is impaired renal excretion, not cardiac pump dysfunction, as in this case.
*Liver cirrhosis*
- **Liver cirrhosis** can lead to **ascites** and **peripheral edema** due to low albumin and portal hypertension.
- Elevate JVP is not a typical feature of cirrhosis unless there is a co-existing cardiac condition.
Varicose Veins and Lymphatics Indian Medical PG Question 4: A patient presents with dull aching pain and tortuous veins in both lower limbs. Which test would be appropriate for evaluating saphenofemoral junction (SFJ) incompetence?
- A. Fegan's test
- B. Brodie Trendelenburg test (Correct Answer)
- C. Modified Perthes test
- D. Morrissey test
Varicose Veins and Lymphatics Explanation: ***Brodie Trendelenburg test***
- This test evaluates **venous valve competence** at the saphenofemoral junction (SFJ) by observing the rate of venous refilling after emptying the superficial veins in the supine position and then standing.
- Quick refilling of veins upon standing, particularly after compression of the SFJ, suggests **SFJ incompetence**.
*Fegan's test*
- This test is used to locate **incompetent perforating veins** by palpating for defects in the fascia after emptying the veins and applying compression.
- It does not directly assess the competence of the saphenofemoral junction.
*Modified Perthes test*
- The Perthes test assesses the **patency of deep veins** and the competence of perforating veins by observing the disappearance of superficial veins during exercise with a tourniquet applied.
- It primarily differentiates between superficial and deep venous insufficiency, not specifically SFJ incompetence.
*Morrissey test*
- This test (also known as the percussion test) involves percussing an incompetent vein distally and palpating proximally to detect a transmitted thrill, indicating **venous incompetence**.
- While it helps identify reflux, it is less specific for SFJ incompetence compared to the Brodie Trendelenburg test.
Varicose Veins and Lymphatics Indian Medical PG Question 5: Identify the condition given in the image below?
- A. Chronic lymphedema (Correct Answer)
- B. Cushing syndrome
- C. Osteoporosis
- D. None of the options
Varicose Veins and Lymphatics Explanation: ***Chronic lymphedema***
- The image shows a **swollen foot** with **thickened, dry, and hyperkeratotic skin**, and **deep skin folds**, particularly between the toes. This is characteristic of **chronic lymphedema** due to impaired lymphatic drainage.
- The presence of the **Stemmer's sign** (inability to pinch and lift the skin at the base of the second toe) is a common finding in lymphedema, which can be inferred from the overall appearance of the toes.
*Cushing syndrome*
- Cushing syndrome is characterized by **central obesity**, **moon facies**, **buffalo hump**, and **thin, fragile skin** with **striae**, not typically severe localized edema and skin changes as seen in the image.
- While fluid retention can occur, it does not manifest as the characteristic cutaneous changes of chronic lymphedema.
*Osteoporosis*
- Osteoporosis is a condition of **decreased bone density**, making bones fragile and prone to fractures.
- It does not present with visible skin changes or edema as depicted in the image.
*None of the options*
- The image clearly shows severe manifestations identifiable as **chronic lymphedema**, therefore one of the provided options is correct.
Varicose Veins and Lymphatics Indian Medical PG Question 6: Which of the following are seen in chronic lymphedema?
- A. Stemmer's sign
- B. Square toes
- C. All of the options (Correct Answer)
- D. Hyperkeratosis
Varicose Veins and Lymphatics Explanation: ***All of the options***
- **Chronic lymphedema** leads to significant tissue changes due to persistent fluid accumulation and inflammation, resulting in all the described clinical signs.
- The combination of **Stemmer's sign**, **square toes**, and **hyperkeratosis** are classic indicators of advanced lymphedema, marking specific stages of its progression.
*Square toes*
- **Square toes** are a distinctive feature of chronic lymphedema, occurring due to protein-rich fluid deposition and fibrosis in the dorsum of the foot, specifically the toes.
- The fibrosis leads to tissue thickening and hardening, making the toes appear "squared off" rather than rounded.
*Stemmer's sign*
- **Stemmer's sign** is a hallmark physical finding in lymphedema, defined as the inability to pinch and lift a fold of skin at the base of the second toe or middle finger.
- This inability indicates **fibrotic thickening** of the skin and subcutaneous tissue due to persistent lymphatic fluid buildup.
*Hyperkeratosis*
- **Hyperkeratosis** refers to the thickening of the stratum corneum (outermost layer of the epidermis) and is a common dermatological manifestation of **chronic lymphedema**.
- It results from chronic inflammation, impaired lymphatic drainage, and subsequent protein deposition, leading to rough, warty skin texture.
Varicose Veins and Lymphatics Indian Medical PG Question 7: 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
Varicose Veins and Lymphatics 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.
Varicose Veins and Lymphatics Indian Medical PG Question 8: Fluorescein dye study is done to detect:
- A. Retinal vascular pathology (Correct Answer)
- B. Posterior segment of eye
- C. Assess retinal vascular conditions in babies
- D. Macular vascular pathology
Varicose Veins and Lymphatics Explanation: ***Retinal vascular pathology***
- **Fluorescein angiography** is a diagnostic procedure using a fluorescent dye to visualize and study blood flow in the **retinal blood vessels**.
- It helps detect and characterize various retinal vascular conditions like **diabetic retinopathy**, **retinal vein occlusions**, and **macular edema**.
*Assess retinal vascular conditions in babies*
- While fluorescein angiography can be performed in babies, it's generally avoided due to the need for sedation and potential risks, making it less routine than for adult retinal conditions.
- The primary purpose is broader than just babies; it's used across all age groups where retinal vascular pathology is suspected.
*Macular vascular pathology*
- **Macular vascular pathology** is a specific type of retinal vascular pathology, but the dye study assesses the entire retinal vasculature, not just the macula.
- Focusing solely on the macula would be an incomplete description of the widespread utility of fluorescein angiography.
*Posterior segment of eye*
- The **posterior segment** includes structures beyond just the retina, such as the choroid and optic nerve.
- While fluorescein angiography provides some information about choroidal circulation, its primary and most detailed application is for evaluating the **retinal vasculature**.
Varicose Veins and Lymphatics Indian Medical PG Question 9: Which type of blood vessel is most commonly affected in hypersensitivity vasculitis?
- A. Postcapillary venules (Correct Answer)
- B. Arterioles
- C. Veins
- D. Capillaries
Varicose Veins and Lymphatics Explanation: ***Postcapillary venules***
- Hypersensitivity vasculitis primarily affects **postcapillary venules**, leading to immune complex deposition and subsequent inflammation [1].
- This type of vasculitis results in **nonspecific inflammation**, commonly seen in conditions like **drug reactions** and **infections**.
- The immune complex vasculitis typically involves **small vessels such as the vascular plexus of the skin**, which features neutrophilic infiltration [2].
*Veins*
- While veins can be involved in various vascular diseases, they are not specifically characteristic of **hypersensitivity vasculitis**.
- This type of vasculitis is more centered around **smaller vessels**, particularly venules, rather than the larger venous systems.
*Capillaries*
- Capillaries are involved in many vascular conditions, but hypersensitivity vasculitis particularly correlates with **venular structures**.
- The immune response seen in hypersensitivity vasculitis is more pronounced in **postcapillary venules**, leading to specific symptoms.
*Aerioles*
- "Aerioles" may refer to arterioles, which are primarily associated with **hypertensive and ischemic events** rather than vasculitis.
- Hypersensitivity vasculitis is primarily due to **post-capillary venule** inflammation rather than changes in arterioles.

Varicose Veins and Lymphatics Indian Medical PG Question 10: Surgery in varicose veins is NOT attempted in the presence of which of the following?
- A. Deep vein thrombosis (Correct Answer)
- B. Multiple incompetent perforators
- C. Varicose veins with leg ulcer
- D. None of the above
Varicose Veins and Lymphatics Explanation: ***Deep vein thrombosis***
- **Surgery in varicose veins is absolutely contraindicated in the presence of DVT** (both acute and chronic)
- In **acute DVT**, the deep venous system is already compromised, and removing superficial veins could further impair venous return and worsen the thrombotic state
- In **chronic DVT with post-thrombotic syndrome**, the deep veins may be occluded or heavily damaged, and the superficial varicosities often serve as **crucial collateral vessels** to maintain venous drainage—their removal would be detrimental
- Surgery should only be considered after complete resolution of acute DVT and adequate anticoagulation
*Multiple incompetent perforators*
- **NOT a contraindication**—incompetent perforators are actually a common indication for surgical treatment
- Incompetent perforators contribute to venous insufficiency and recurrent varicose veins
- Can be addressed surgically with **subfascial endoscopic perforator surgery (SEPS)** or endovenous ablation techniques
- Their presence often indicates need for more comprehensive treatment alongside superficial venous surgery
*Varicose veins with leg ulcer*
- **NOT a contraindication**—venous leg ulcers are actually an **indication for varicose vein surgery**
- Leg ulcers result from chronic venous hypertension due to venous insufficiency
- Surgical treatment (saphenous vein ablation, ligation and stripping, or sclerotherapy) reduces venous hypertension and improves venous drainage
- Surgery promotes ulcer healing and prevents recurrence when combined with appropriate wound care
*None of the above*
- Incorrect because **Deep Vein Thrombosis (DVT) is a well-established contraindication** to varicose vein surgery
