Which method is used depends on your child’s condition and any underlying problems. Mechanical thrombectomy – using tiny surgical tools, the doctor breaks down the clot into smaller pieces that can then be sucked out of the blood vessel.The medicine is given through a larger cannula inserted into the clot in a short procedure under general anaesthetic in the Interventional Radiology department. Catheter-directed thrombolysis – the clot-busting medicine is delivered into the centre of the clot over several hours or days.The medicine travels through the blood vessels breaking up clots elsewhere in the body. Systemic thrombolysis – a clot-busting medicine is given through a cannula (thin plastic tube) into a vein in your child’s hand or foot.Once the clot has been identified, there are three ways that it can be treated: Clots can also form after an operation, particularly if a person cannot move around normally. Some people’s blood is ‘stickier’ than others, because of other medical problems they have, or because of a family tendency to form blood clots. If one forms in an artery, the blood cannot reach the area supplied by the artery.īlood clots can form for many reasons. ![]() If a blood clot forms inside a vein and blocks it, the part of the body supplied by that vein becomes swollen as the blood is unable to flow back towards the heart. This page from Great Ormond Street Hospital (GOSH) explains about how a blood clot is diagnosed and the various forms of treatment (thrombolysis and thrombectomy) that may follow.Blood clots can disrupt blood flow, depriving the part of the body supplied by the blood vessel of oxygen, which could lead to tissue damage if untreated. However, when a blood clot forms inside a blood vessel, it can cause serious problems. In normal circumstances, clotting is a good thing as it prevents blood loss from an injury such as a cut or graze. ![]() Blood contains cells called platelets and a substance called fibrinogen that allow the blood to clot.
