a CT and a venogram (angiography) with dye showed that my SVC was almost completely blocked. there were blood clots
in my left subclavian vein and lots of blood
in my pericard.
i did have the classic symptoms: shortness of breath, pressure in my head (which got worse when bended over or layed down), problems swallowing, sometimes chest pain, swellings in my face (in the mornings), cough. it all started with shortness of breath, and then one symptom after the other followed.
