If you were asked to say where you believe that the majority of truck crashes occur, you'd probably say on an interstate. The truth is that nearly two-thirds of truck accidents happen in parking lots though.
Picture this: You're adventuring in a remote area of a national park, enjoying the scenery and fresh air, when an unsettling rattling sounds from directly behind you. You freeze for a moment. And then whip around just in time to see the fierce rattlesnake leap up at you. You jump back, but you're too late. The fangs sink into that small, exposed patch of skin between your sock and pants. You kick at it, and it slithers away, but the venom is working its way inside you. You start to feel dizzy as you pull out your phone and dial for help. Your consciousness fades in and out as you lay on the grass. You hear voices and people lift you. A deafening sound. You open your eyes long enough to see the wilderness fly by underneath you. You feel the jostling as you are moved from the helicopter onto a gurney. You finally regain full consciousness and realize you are in a hospital bed.
Doctors commonly insert inferior vena cava (IVC) filters into the body's largest vein in order to reduce a patient's risk of developing a blood clot after suffering an injury or having a surgery performed on them. They're used as an alternative to prescription blood thinners for those at risk for either deep vein thrombosis (DVT) or a pulmonary embolism (PE).
