Posterior Tibial Artery Complete Blockage

Posterior Tibial Artery (PTA) Complete Blockage occurs when the blood flow through the posterior tibial artery is completely obstructed. In simpler terms, it’s like a roadblock in the pathway that supplies blood to the lower leg and foot. Let’s break down this complex topic into easy-to-understand sections.

Types of Posterior Tibial Artery Complete Blockage:

There is one primary type – total occlusion of the posterior tibial artery, meaning the artery is completely blocked, impeding normal blood flow.

Causes of Posterior Tibial Artery Complete Blockage:

• Atherosclerosis: Hardening and narrowing of arteries due to plaque buildup.
• Embolism: A clot or debris that travels through the bloodstream and blocks the artery.
• Thrombosis: Formation of a blood clot within the artery.
• Diabetes: Elevated blood sugar levels damaging blood vessels.
• Smoking: Harmful chemicals in tobacco affecting blood vessel health.
• High Blood Pressure: Puts strain on arteries, making them prone to blockages.
• Hypercholesterolemia: High levels of cholesterol contributing to plaque formation.
• Trauma: Injuries leading to artery damage.
• Inflammation: Conditions like vasculitis causing artery inflammation.
• Genetic Factors: Predisposition to arterial issues.
• Obesity: Excess weight putting strain on the cardiovascular system.
• Aging: Natural wear and tear on arteries.
• Autoimmune Diseases: Conditions where the immune system attacks the arteries.

• Capillaroscopy: Examines the tiny blood vessels in the nailfold.
• Fluorescein Angiography: Involves injecting a dye to visualize blood vessels in the retina.
• Transcutaneous Oxygen Tension (TcPO2) Testing: Measures oxygen levels in the skin.
• Blood Coagulation Tests: Assess the blood’s ability to clot.
• Echocardiogram: Ultrasound of the heart to check for potential sources of emboli.
• Electrocardiogram (ECG or EKG): Records the heart’s electrical activity.
• Stress Echocardiogram: Evaluates heart function during physical stress.
• Skin Perfusion Pressure: Measures pressure needed to maintain blood flow in the skin.

Treatments for Posterior Tibial Artery Complete Blockage:

• Lifestyle Changes: Quitting smoking, maintaining a healthy weight, and regular exercise.
• Medication Management: Antiplatelet drugs, anticoagulants, and cholesterol-lowering medications.
• Blood Pressure Control: Medications to manage hypertension.
