The facts most likely to be tested
Varicose veins result from venous valvular incompetence leading to venous reflux and venous hypertension.
The most common clinical presentation is dull, aching leg pain that worsens with prolonged standing and improves with leg elevation.
Physical examination reveals dilated, tortuous, palpable veins typically involving the greater saphenous vein distribution.
The gold standard diagnostic test for confirming venous reflux is venous duplex ultrasonography.
Chronic venous insufficiency may progress to stasis dermatitis, characterized by hyperpigmentation and hemosiderin deposition in the medial malleolus area.
Initial management for symptomatic patients is conservative therapy consisting of leg elevation and compression stockings.
Definitive treatment for refractory cases involves endovenous thermal ablation or sclerotherapy to eliminate the incompetent venous segment.
Vignette unlocked
A 54-year-old female presents to the clinic complaining of a heavy, aching sensation in her lower extremities that worsens throughout the day. She works as a cashier and stands for 8 hours daily. Physical examination reveals dilated, tortuous, bluish vessels along the medial aspect of her left calf. There is mild brownish discoloration and induration of the skin near the medial malleolus. Venous duplex ultrasonography demonstrates retrograde flow in the greater saphenous vein lasting 2 seconds.
What is the most appropriate initial management for this patient?
Leg elevation and compression stockings
The patient presents with symptomatic varicose veins and early signs of chronic venous insufficiency; conservative management with compression therapy is the first-line treatment before considering procedural intervention.

Etiology / Epidemiology
Caused by venous valvular incompetence and venous hypertension. Common in females, pregnancy, and those with prolonged standing.
Clinical Manifestations
Dilated, tortuous superficial veins. Corona phlebectatica and hemosiderin deposition are classic signs of chronic venous insufficiency.
Diagnosis
Duplex ultrasound is the gold standard to confirm reflux >0.5 seconds.
Treatment
Leg elevation and compression stockings are first-line. Avoid in peripheral arterial disease.
Prognosis
Risk of stasis dermatitis and venous ulcers. Monitor for superficial thrombophlebitis.

Epidemiology & Etiology
Prevalence increases with age, female gender, and family history. Prolonged standing and obesity increase hydrostatic pressure, leading to valvular failure. Pregnancy is a major risk factor due to hormonal changes and mechanical compression of the vena cava.
Pertinent Anatomy
Involves the greater saphenous vein and its tributaries. Valvular incompetence allows retrograde flow, causing venous pooling in the lower extremities.
Pathophysiology
Venous hypertension results from valvular incompetence or obstruction. Chronic high pressure leads to capillary leakage of fibrinogen and red blood cells into the dermis. This triggers an inflammatory cascade resulting in lipodermatosclerosis and skin ulceration.
Clinical Manifestations
Patients present with dull, aching pain or heaviness that worsens throughout the day. Look for dilated, tortuous veins and corona phlebectatica (ankle telangiectasias). Red flags include sudden swelling, warmth, or tenderness suggesting superficial thrombophlebitis or DVT.
Diagnosis
Duplex ultrasound is the diagnostic test of choice. It identifies reflux >0.5 seconds in the saphenous or deep veins. Ankle-brachial index (ABI) should be performed to rule out peripheral arterial disease before initiating compression therapy.
Treatment
Initial management is conservative with leg elevation and compression stockings. If symptoms persist, endovenous thermal ablation or sclerotherapy are indicated. Contraindications for compression include an ABI <0.5, as this indicates severe arterial insufficiency.
Prognosis
Most patients remain stable with conservative care. Complications include stasis dermatitis, venous stasis ulcers, and hemorrhage. Long-term monitoring is required for patients with signs of chronic venous insufficiency.
Differential Diagnosis
DVT: unilateral swelling and warmth
Peripheral Arterial Disease: diminished pulses and claudication
Lymphedema: non-pitting edema and Stemmer sign
Cellulitis: fever and spreading erythema
Baker's Cyst: posterior knee mass
