Study Notes

Ischemic Pain

Ischemic pain is a result of lactic acid build-up due to anaerobic metabolism during exercise.
Pain subsides once exercise stops and lactic acid is cleared.
Ischemic muscle pain caused by constant exercise resolves within 10 minutes or less with rest.
Reproducible and often accompanied by paresthesia (numbness, tingling) due to nerve tissue ischemia.

Peripheral Arterial Disease (PAD)

PAD is caused by atherosclerosis, leading to narrowing and blockage of arteries.
Common symptoms include:
- Intermittent claudication (pain with walking, relieved by rest).
- Rest pain (pain at rest, often in feet, can be severe and debilitating).
- Paresthesia (numbness, tingling)
- Loss of hair on lower legs, shiny skin, and thickened toenails.
- Diminished or absent pulses (pedal, popliteal, femoral).
PAD is diagnosed using:
- Ankle-brachial index (ABI) to assess the severity of blockage.
- Duplex imaging: Ultrasound to visualise blood flow in arteries.
- Angiography: X-ray with contrast dye to visualise arteries.
- Magnetic resonance angiography (MRA): MRI to visualise arteries.
- Computed tomography angiography (CTA).
Treatment options include:
- Lifestyle modifications: Tobacco cessation, exercise, healthy diet, weight loss.
- Medications: Antiplatelet medications, statins, vasodilators, pain medication.
- Surgical interventions:
  - Angioplasty (balloon dilation of narrowed arteries).
  - Stent placement (tiny mesh tube inserted to keep arteries open).
  - Bypass surgery (grafting a healthy vessel to bypass the blocked segment).

Abdominal Aortic Aneurysm (AAA)

AAA is a bulge or weakening in the aorta, the main artery in the abdomen.
Often asymptomatic but can cause back pain, abdominal pain, altered bowel habits, and intermittent claudication.
Pulsating mass in the periumbilical area may be present.
Bruits can be heard with auscultation over the aneurysm.
Complications:
- Rupture: Serious complication with high mortality rate, causing severe back pain, tachycardia, hypotension, pale clammy skin, decreased urine output, altered level of consciousness and abdominal tenderness.
- Cardiac tamponade.
- Occlusion of arterial supply to vital organs (spinal cord, kidneys, mesentery).
Treatment:
- When asymptomatic: Monitoring for growth of the aneurysm using ultrasound and CT scan.
- Surgical intervention: If aneurysm is growing or symptomatic.
If ruptured, immediate surgical intervention is required.

Buerger Disease

Also known as thromboangiitis obliterans.
Associated with smoking and characterized by inflammation and clotting in small and medium-sized arteries and veins, primarily in the hands and feet.
Symptoms include:
- Claudication pain in feet and lower extremities, worse at night.
- Cold sensitivity.
- Gangrene ulcers.
Treatment:
- Smoking cessation is essential.
- Vasodilator medications.
- Pain management.
- Ulcer management.

Raynaud Phenomenon/Disease

Abnormal response to cold or stress, causing painful spasms in small arteries.
Characterized by color changes in fingers and toes:
- White (pallor) due to vasoconstriction.
- Blue (cyanosis) due to lack of oxygenated blood.
- Red (rubor) due to vasodilation.
More common in women and may have an autoimmune component.
Treatment:
- Similar to Buerger's disease.

Subclavian Steal Syndrome

Caused by blockage of the subclavian artery (the main artery to the arm).
Blood flow is "stolen” from the vertebral artery in the neck to supply the arm, leading to:
- Ischemia in the arm (pain, numbness, tingling).
- Arm fatigue, weakness.
- Difference in blood pressure between arms.
Treatment:
- Lifestyle modifications (avoiding aggravating activities).
- Surgical intervention may be needed for severe symptoms.

Thoracic Outlet Syndrome

Compression of the subclavian artery and/or brachial plexus (nerves that supply the arm) in the space between the collarbone and first rib.
Causes:
- Anatomical variations, trauma or repetitive arm movements.
Symptoms:
- Pain, numbness, and tingling in the arm and hand.
- Weakness and fatigue in the arm.
- Cold and discoloration of fingers.
- Symptoms may worsen with overhead activity or arm elevation.
Treatment:
- Physical therapy.
- Avoiding aggravating positions.
- Surgical intervention may be needed for severe symptoms.

Peripheral Venous Disease (PVD)

Caused by venous insufficiency, a condition where veins are unable to return blood to the heart effectively due to valvular incompetence, deep vein thrombosis (DVT), or other factors.
Symptoms:
- Leg swelling, pain, and fatigue.
- Varicose veins (dilated, twisted veins).
- Skin discoloration (bruising, redness).
- Venous leg ulcers (open sores on lower legs).
Diagnosis:
- Physical exam.
- Duplex ultrasound.
- Venography.
- CT scan or MRI.
Treatment:
- Lifestyle modifications (exercise, compression stockings, weight loss).
- Sclerotherapy (injecting a solution to close varicose veins).
- Surgical intervention may be needed for severe symptoms.

Venous Thromboembolism (VTE)

DVT is a blood clot in a deep vein, most often in the legs.
PE is a pulmonary embolism, a blood clot that travels to the lungs.
Risk factors:
- Virchow’s triad (venous stasis, endothelial damage, hypercoagulability).
Symptoms:
- Unilateral leg swelling, pain, redness, warmth.
- The classic symptom of PE is shortness of breath, but there may also be chest pain, cough, and fever.
Diagnosis:
- Venous duplex ultrasound (first-line).
- D-dimer testing.
Treatment:
- Anticoagulants (heparin, warfarin, novel oral anticoagulants) to thin the blood and prevent clot growth.
- Thrombolytic therapy (drugs to dissolve clots).
- Venous filters may be placed in the vena cava to prevent clots from traveling to the lungs.

Varicose Veins

Dilated, tortuous veins, usually in the legs.
Risk factors:
- Female gender.
- Age.
- Obesity.
- Family history.
- Prolonged standing or sitting.
- Pregnancy.
Symptoms:
- Achy pain, heaviness, and fatigue in the legs.
- Visible, bulging veins.
- Leg swelling.
- Skin changes such as discoloration, itching, and tenderness.
Diagnosis:
- Physical exam.
- Duplex ultrasound.
Treatment:
- Lifestyle modifications (compression stockings, exercise, avoiding prolonged standing).
- Sclerotherapy (injecting a solution to close varicose veins).
- Radiofrequency ablation (using heat to seal varicose veins).
- Laser treatment.
- Surgical removal of varicose veins.
