A thrombectomy is a medical procedure to mechanically remove a blood clot (thrombus) from a blood vessel, crucial for restoring blood flow in conditions like ischemic stroke, heart attack, or pulmonary embolism, using either minimally invasive catheter-based methods (aspiration, stent retrievers) or open surgery, often performed quickly to prevent severe damage. 
Types
  • Mechanical/Endovascular Thrombectomy: Minimally invasive, using catheters inserted via groin to reach the clot and remove it with suction, stents, or other devices.
  • Surgical Thrombectomy: More invasive, involving open surgery to access and remove the clot from arteries or veins. 
Common Uses
  • Ischemic Stroke: Removing clots blocking brain arteries to save brain tissue.
  • Pulmonary Embolism (PE): Clearing clots from lung arteries to reduce heart strain.
  • Deep Vein Thrombosis (DVT): Removing clots from legs to prevent complications like post-thrombotic syndrome.
  • Myocardial Infarction (Heart Attack): Clearing clots from heart arteries. 
How it Works (Mechanical Thrombectomy)
  1. Access: A catheter is inserted into a blood vessel (usually in the groin).
  2. Navigation: Guided by imaging, it travels up to the blocked vessel.
  3. Clot Removal: Devices like stent retrievers trap the clot or aspiration catheters suction it out.
  4. Restoration: Blood flow is quickly restored, minimizing damage. 
Key Points

  • Urgency: Especially for stroke, speed is critical, often within hours of symptom onset.
  • Benefit: Significantly improves outcomes and reduces disability by restoring circulation.
