What is DVT and PE?

The device

 

DVT, or deep vein thrombosis, is the formation and release of blood clots (thrombi) inside the deep veins, most often in the legs. PE (pulmonary embolism) occurs when one of these thrombi becomes lodged in the lungs. Together, these conditions are referred to as VTE, or venous thromboembolism. DVT can cause significant, crippling damage. PE is a life-threatening event.

 

 

Causes

 

• Changes in intrathoracic pressure associated with anesthesia and surgical procedures can reduce venous return from the extremities to the heart.

• Surgical and therapeutic trauma can set up a chemical “chain reaction” that causes proliferation of clotting factors in the deep veins.

• And, most importantly: Patient immobility, for hours, days, or weeks, enhances venous stasis because the “muscle pump” and “foot pump” of the legs, which are activated by physical activity, are in disuse.
