Vascular obstructions occur when blood vessels become blocked, preventing blood from flowing properly. This can happen due to various reasons, such as blood clots, plaque buildup, or compression from surrounding tissues. When blood flow is restricted, it can lead to serious health issues, including pain, tissue damage, or even organ failure. Common types of vascular obstructions include deep vein thrombosis (DVT) and arterial occlusion. Symptoms may vary depending on the location and severity of the blockage, but they often include swelling, redness, or numbness in the affected area. Early detection and treatment are crucial to prevent complications and restore normal blood flow.
