深静脉血栓(DVT)对病人是一种威胁,如果栓子很大,造成慢性静脉机能不全。如果栓子从静脉壁脱落游走到肺部,将发生致命的肺栓塞。如何预防DVT,必须熟悉其病因、症状和体征,诊断性试验,抗凝治疗以及合理的护理措施。 (一)栓子游走的危险性静脉血栓大多数在下肢形成,通常发生在小腿部,约15%向上游走,当越过腘窝平面后有肺栓塞的危险。一旦股静脉或髂静脉形成血栓,危险性更大。不游走的栓子逐渐消退,静脉再次通畅,但是该处的静脉瓣被损坏,导致静脉功能不全,表现腿痛,肿胀、皮肤色泽改变,
Deep venous thrombosis (DVT) is a threat to the patient and can cause chronic venous insufficiency if the emboli are large. A fatal pulmonary embolism will occur if the emboli break off from the wall of the vein and travel to the lungs. How to prevent DVT, must be familiar with its etiology, symptoms and signs, diagnostic tests, anticoagulant therapy and reasonable care measures. (A) Most of the dangerous venous thrombi swimming in the lower limbs, usually occurs in the lower leg, about 15% upstream, risk of pulmonary embolism after crossing the popliteal plane. Once the thrombosis of the femoral vein or iliac vein, the risk is greater. The non-migratory emboli subsided and the vein was once again unobstructed, but the venous valves in the area were damaged, resulting in venous insufficiency, leg pain, swelling, skin color changes,
