Pathophysiology

Weakened vein walls dilate under sustained venous pressure, causing the valves to become incompetent. This creates a cycle of reflux, further dilation, and worsening valve failure. Blood pools in the superficial venous system, creating tortuous, distended veins visible under the skin. Connect Varicose Veins to bedside cues you will reassess first: vitals trends, work of breathing, perfusion, mentation, and pain or ischemic equivalents when relevant. Boards reward recognizing when subtle instability outweighs reassurance, then selecting nursing actions that protect airway, circulation, and neurologic status before routine tasks.
