thrombectomy
The mechanical removal of blood clots from vessels using specialized catheter-based devices.
Full Definition
Thrombectomy is an endovascular procedure that involves the physical extraction of thromboembolic material from blood vessels using various catheter-based techniques. Modern thrombectomy devices include stent retrievers, aspiration catheters, and mechanical clot removal systems. The procedure is time-critical in acute stroke treatment, where rapid recanalization of large vessel occlusions can significantly improve neurological outcomes. In peripheral applications, thrombectomy is used to treat acute limb ischemia and pulmonary embolism. Success depends on clot composition, location, and time from symptom onset.
Usage
Usage note: Specify the technique used (aspiration, stent retriever, etc.) when documenting thrombectomy procedures.
