Venous thrombosis of the upper extremity can be very minor (superficial phlebitis from IV's) or quite dramatic (effort thrombosis of the axillary or subclavian veins). Rarely is it life threatening. Long-term sequelae are not seen.
上肢静脉血栓形成可能非常轻微(静脉输液引起的浅静脉炎),也可能相当严重(腋静脉或锁骨下静脉的用力性血栓形成)。它很少危及生命。不会出现长期后遗症。
