I77: Other disorders of arteries and arterioles

The group of conditions titled "Other disorders of arteries and arterioles" comprises various illnesses related to the abnormal functioning or structure of the arteries and arterioles. These conditions can originate from several causes, including age-related changes, congenital abnormalities, trauma, or diseases like atherosclerosis and hypertension. The symptoms vary according to which artery or arteriole is affected but may include pain, fatigue, and decreased functioning of the organ supplied by the affected artery. In severe cases, if left untreated, these conditions may lead to organ damage, due to the reduced blood supply, which can cause more serious illnesses. These disorders predominantly affect the cardiovascular system, and their progression largely depends on the specific condition, its cause, and its location within the body. Early detection and treatment are crucial to managing these conditions effectively and preventing further damage.
