Sorry to hear that you had your IJV thrombosed.
In one of your posts about your first treatment in Poland you had commented:
I then sent my scans to Dr Dake. He saw that both my jugular veins were pancaked flat at C2 and a further occlusion was seen in the lower left jugular
I went to Poland to be treated by Dr Simka and he saw the problem with the left lower jugular it was obvious but did not see the stenosis that Dr Dake had seen high up. I did mention it but he didn't think it was relevant or too risky to treat (not sure)
So I'm wondering, whether the problem that Dr Dake spotted on your jugular and that Simka did not treat could be related to your now thrombosed jugular.
Were you on blood thinners after your first treatment? I've read in Dr Sclafani that he regretted not to give blood thinners to some of his first patients treated with angioplasty. Apparently in one case the vein thrombosed and was lost forever (although it was quite sick to start with).
Also, have you been tested for thrombophilia? I think I had mentioned to you that I have been tested for that condition (propensity to develop thrombosis) as it has been reported it can cause my neuro condition (transverse myelitis). I was negative for thrombophilia, which was a relief so there were less chances of developing complications after the angioplasty.
