VENOUS THROMBOEMBOLISM - MANAGEMENT
Deep vein thrombosis is a frequent manifestation of venous thromboembolism in which there is a blood clot blocking a deep vein.
Clinical findings are important to the diagnosis of deep vein thrombosis but are poor predictors of the presence or severity of thrombosis.
Pulmonary embolism is the blockage of the blood vessels in the lungs usually due to blood clots from the veins, especially veins in the legs and pelvis.
Dyspnea, pleuritic chest pain, syncope and tachypnea occur in most cases of pulmonary embolism.
Massive pulmonary embolism has the prime symptom of dyspnea and systemic arterial hypotension, that requires pressor support, is the predominant sign.

Differential Diagnosis

  • Since pain and swelling are common presenting complaints, DVT must be differentiated from other causes including the following:
    • Muscle strain, rupture or tear
    • Leg swelling in paralyzed leg
    • Lymphangitis, lymphedema
    • Cellulitis
    • Ruptured popliteal cyst (Baker’s cyst)
    • Venous insufficiency
    • Superficial thrombophlebitis
  • Differential diagnoses for massive pulmonary embolism include the following: 
    • Cardiogenic shock
    • Cardiac tamponade
    • Aortic dissection
    • Pneumonia
    • Massive myocardial infarction

Patients with greater ischaemia who underwent positron emission tomography (PET) myocardial perfusion imaging (MPI) have better survival with early revascularization, reports a study. Exploratory analyses reveal a lower threshold than that previously reported for single-photon emission computed tomography (SPECT).
