Ans:B. Deep Vein Thrombosis.
Deep venous thrombosis (DVT)
- It is a manifestation of venous thromboembolism .
Symptoms of DVT may include the following:
- Edema – Most specific symptom
- Leg pain – Occurs in 50% of patients but is nonspecific
- Tenderness – Occurs in 75% of patients
- Warmth or erythema of the skin over the area of thrombosis
- Clinical symptoms of pulmonary embolism as the primary manifestation.
Physical findings in DVT may include the following:
- Calf pain on dorsiflexion of the foot (Homans sign)
- A palpable, indurated, cordlike, tender subcutaneous venous segment
- Variable discoloration of the lower extremity
- Blanched appearance of the leg because of edema (relatively rare)
Potential complications of DVT include the following:
- As many as 40% of patients have silent PE when symptomatic DVT is diagnosed 
- Paradoxic emboli (rare)
- Recurrent DVT
- Postthrombotic syndrome (PTS).
- Ultrasound Doppler and duplex imaging of the calf veins, venography,D-Dimer
- Coagulation studies (eg, prothrombin time and activated partial thromboplastin time) to evaluate for a hypercoagulable state.
Treatment options for DVT include the following:
- Anticoagulation (mainstay of therapy) – Heparins, warfarin, factor Xa inhibitors, etc.
- Pharmacologic thrombolysis
- Endovascular and surgical interventions:
- Thrombus removal with catheter-directed thrombolysis
- Mechanical thrombectomy
- Stenting of venous obstruction
- Physical measures (eg, elastic compression stockings and ambulation)
