NUR 203 Chapter Notes - Chapter 15: Vasa Vasorum, Central Venous Catheter, Varicose Veins
Document Summary
Peripheral arterial disease (pad) - stenotic, occlusive, and aneurysmal disease of the aorta, its visceral arterial branches, and the arteries of the lower extremities, but not the coronary arteries. Risk of death from myocardial infarction and stroke triples in adults with pad. Venous thrombosis or thrombophlebitis - presence of a thrombus or clot in a vein that is accompanied by an inflammatory response in the vein wall. Thrombi in the superficial veins are usually a response to vessel injury and rarely cause complications. Dislodgement of the thrombus produces an embolus that can travel to the lungs, causing pulmonary embolism and possible death. Dvt pose a grave danger to patients. Lower extremity dvt is seen in ~1% of adults above age 60. Dvt in the upper extremity now represents about 10% of cases of dvt, reflecting complications from increased placement of central venous catheters, cardiac pacemakers, and defibrillators.
