Other embolisation: nosebleeds, tumours and trauma

Embolisation closes blood vessels on purpose. A catheter is guided to the vessel, and tiny particles, coils or liquid block it. It is used where controlling blood flow helps. Most nosebleeds (epistaxis) stop with pressure, packing or cautery by an ear, nose and throat doctor. Embolisation is considered for a bleed that is severe or keeps coming back despite those steps, and the catheter blocks small branches of the artery supplying the nose. Risks are uncommon but real: stroke, facial pain or numbness, and damage to skin or tissue. Some tumours of the head, neck and brain have a rich blood supply, so embolisation before surgery can reduce bleeding during the operation, and it may also be used to relieve symptoms. After an injury to the head, face or neck, a damaged vessel may bleed or form a weak bulge, and embolisation can close it, sometimes as an emergency. The risks depend on the area, and the team will explain them before any planned procedure. Heavy nosebleed? Sit forward, pinch the soft part of the nose for 10 to 15 minutes, and go to an emergency department if it does not stop or you feel faint.
