Differential Diagnosis for Bilateral Edema of Feet in a Patient with History of CVA and Current Smoker

  • Single Most Likely Diagnosis
    • Chronic Venous Insufficiency: This condition is common in smokers and can lead to bilateral edema of the feet due to the incompetence of venous valves, causing blood to pool in the legs.
  • Other Likely Diagnoses
    • Heart Failure: Given the patient's history of CVA (cerebrovascular accident), there's a possibility of underlying cardiac issues leading to heart failure, which can cause peripheral edema.
    • Hypertension: Uncontrolled hypertension, which is a risk factor for CVA, can also lead to kidney damage and subsequently cause edema.
    • Peripheral Artery Disease (PAD): Smoking is a significant risk factor for PAD, which can cause edema among other symptoms due to reduced blood flow to the limbs.
  • Do Not Miss Diagnoses
    • Deep Vein Thrombosis (DVT): Although less likely than chronic conditions, DVT is a critical diagnosis to consider due to its potential for severe complications like pulmonary embolism, especially in a patient with a history of CVA and smoking.
    • Nephrotic Syndrome: This condition, characterized by significant proteinuria, can lead to edema and is important not to miss due to its implications for renal function and the need for specific treatment.
    • Liver Cirrhosis: While less directly related to the patient's history, cirrhosis can cause edema and is a condition that would significantly impact management and prognosis.
  • Rare Diagnoses
    • Lymphedema: This could be a consideration if the edema is non-pitting and there's a history of lymph node removal or radiation, though it's less likely given the bilateral nature and the patient's provided history.
    • Sarcoidosis: A systemic disease that can cause edema among many other symptoms, though it would be an uncommon cause of bilateral foot edema without other systemic symptoms.
    • Myxedema: Associated with hypothyroidism, this condition can cause non-pitting edema but is less likely without other symptoms of thyroid dysfunction.
