Pathophysiology
Clinical meaning
Buerger's disease causes segmental inflammation and thrombosis of small and medium arteries and veins, primarily in the extremities. Unlike atherosclerosis, the vessel wall remains intact but becomes heavily infiltrated with inflammatory cells and thrombus. It occurs almost exclusively in smokers. Connect Buerger's Disease 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.
