Andy thank you for your post. I felt like I wasn't alone. My surgery was just like yours. I have been recently been diagnosed with 2 aneurysms on my spleen. The vascular surgeon I was sent to said because I am at high risk of bleeding out and the surgery is difficult to recover from. he is going to continue following them to see if they get any larger.
Needless to say I live in constant fear of them ruputuring.
I can relate to the Lovenox injections and heparin iv. I also had brain tumor surgery and
I had an embolism on my kidney that ruptured. I almost bled to death. I was in icu for almost a month. No one could explain why this happened. I never had any kidney issues. Currently my INR levels are supposed to be between 3'-3.5 to prevent another stroke. Like you I have 1. 2, 5 and 7.5mg warfarin that they adjust every week.
I am glad I am not alone with this and am truly sorry that you are going through this. My doctors tell me it is complicated and they don't know why this is happening I bought a tshirt thst says RARE . slowly stumping doctors. I get alot of laughs when I go to the doctors. Sometimes I have to laugh to keep from crying. Thank you again.
