May-Thurner Syndrome:
May-Thurner syndrome is a condition that affects blood flow. It occurs when the right iliac artery, which sends blood to your right leg, presses on the left iliac vein, which carries blood from your left leg to your heart. Some people have no symptoms of May-Thurner syndrome. Others develop deep vein thrombosis (DVT) or blood clots in the legs.
Iliac vein compression is common, occurring in about 1 in 5 people. However, many people with iliac vein compression don’t have a formal diagnosis of May-Thurner syndrome. This may be partly because most people don’t have symptoms of May-Thurner syndrome unless they develop DVT.
Not that uncommon. According to Boebert's campaign a stent was put in place after the clot had been removed. That ought to take care of the problem, as long as the diagnosis is correct.
