A suction thrombectomy is a minimally invasive surgical procedure that is performed to remove blood clots inside an artery or a vein. Under normal circumstances, blood flows through the patient’s blood vessels, arteries, and veins. Arteries are responsible for carrying oxygenated blood with nutrients to the body, and the veins are responsible for carrying deoxygenated blood from the organs back to the heart.
In some instances, the blood thickens and clumps up to form a blood clot in the artery or vein. This results in a blockage in the vein or artery that can damage nearby tissue.
During a suction thrombectomy, an IV will be inserted in the arm or hand, through which medicine and an anaesthetic be administered. The vascular surgeon will then, under ultrasound guidance, insert a catheter into the artery or vein. Contrast media is then injected, and x-rays are taken. The blood clot may be injected with a thrombolytic (‘clot buster’) to soften the clot. A suction device is then used to remove the blood clot. After the blood clot has been removed, the blood is thinned with medication, and the cause of the clot is identified and corrected.
