Na, no reason to do that. A superficial isn’t the same as a DVT, they don’t all turn into PEs. They also need to figure out the cause……virchows triad……I’m sure they will test for coagulopathy, maybe not due to vascular damage, perhaps just venous status from the flight. It happens. Most time it’s not a major deal, treat with anti-coag and rule out coagulation disorder. If it’s something like venous stasis from a long car ride or flight, u don’t need to be on anti-coags long term. With superficial clots, they aren’t as serious.
