I'm considering surgery for a small hernia that gives me moderate pain. I've heard I'm not a candidate because of severe risk of post-surgery clots. I'm 70, ET, JAK2+, Factor V Leiden, Coronary Stent, venous reflux and neuropathy in legs, arthritic gout, many previous severe bouts of mesenteric ischemia before going on HU. Mazcd I'm thinking that stopping Warfarin, aspirin, HU, would help to control bleeding. How worried should I be about surgery causing clots down the road?
