Deep vein thrombosis occurs when a blood clot forms in one or more of the deep veins in your body, usually your legs. It may cause pain or swelling, and the pain will often start in your calf, and it can feel like cramping or soreness. It may produce a warm feeling in the affected leg. There might also be red or discolored skin on the leg. Deep vein thrombosis or DVT can be severe because blood clots in your veins can break loose, travel through your bloodstream and lodge in your lungs, which will block blood flow.
The blood clots may be caused by anything that prevents your blood from circulating or clotting normally, such as injury to the vein, surgery, and certain medications and limited movement. A serious complication of deep vein thrombosis is a pulmonary embolism.
Ineffective peripheral tissue perfusion related to venous congestion-rationale: ineffective peripheral tissue perfusion related to venous congestion takes highest priority because venous inflammation and clot formation impede blood flow in a client with dvt. impaired gas exchange related to increased blood flow is incorrect because impaired gas exchange is related to decreased, not increased, blood flow. excess fluid volume related to peripheral vascular disease is inappropriate because theres no evidence that this client has an excess fluid volume. risk for injury related to edema may be warranted but is secondary to ineffective tissue perfusion. client needs category: physiological integrity client needs subcategory: reduction of risk potential cognitive level: application reference: smeltzer, s.c., and bare, b. brunner & suddarths textbook of medical surgical-nursing, 11th ed. philadelphia: lippincott williams & wilkins, 2008, p. 1007.
