Vascular occlusions occur when blood vessels become blocked, preventing blood flow to specific areas of the body. This blockage can be caused by various factors, including blood clots, fatty deposits, or other obstructions. When blood flow is restricted, it can lead to tissue damage and complications, depending on the location and severity of the occlusion. Common types of vascular occlusions include deep vein thrombosis (DVT) and pulmonary embolism (PE). Symptoms may vary but can include pain, swelling, and discoloration in the affected area. Timely diagnosis and treatment are essential to restore blood flow and prevent serious health issues.
