Quizplus · Accepted Answer

Raynaud's phenomenon is a condition in which periodic ischemic attacks affect the extremities of the body, especially the fingers and toes. This is caused by vasospasms of the blood vessels in those areas, leading to decreased blood flow and oxygen delivery to the tissues. Patent ductus arteriosus is a heart defect in which a blood vessel that normally closes shortly after birth remains open, causing blood to flow abnormally between the two main arteries of the heart. Thromboses are blood clots that can form in blood vessels, potentially causing blockages and tissue damage. Varicose veins are enlarged, twisted veins that can occur in the legs due to weakened valves that allow blood to pool in the vessels.
