Normal and abnormal blood vessels. In a brain AVM, blood passes directly from arteries to veins via a tangle of abnormal blood vessels. A brain arteriovenous malformation (AVM) is a tangle of abnormal blood vessels connecting arteries and veins in the brain. The arteries are responsible for taking oxygen-rich blood from the heart to the brain. Veins carry the oxygen-depleted blood back to the lungs and heart.
A blood clot that forms in an artery or an arterial thrombus is a very dangerous clot that can obstruct the flow of blood to major organs and cause complications such as stroke, transient ischemic attack (TIA or mini-stroke), heart attack, or peripheral arterial disease. venous thrombus can occur in the deep veins of the body such as a deep leg vein or a blood vessel of the lung. Deep vein thrombosis (DVT) usually occurs in the large veins of the calf or thigh where it causes pain and inflammation.
