How is iliac vein compression syndrome caused?

summary

Iliac vein compression and (or) the existence of intraluminal abnormal adhesion structure caused by lower extremity and pelvic venous reflux disorders. Iliac vein compression not only causes venous reflux obstruction and lower extremity venous hypertension, but also is one of the causes of lower extremity venous valve insufficiency and superficial varicose veins, and is an important potential factor of secondary iliofemoral vein thrombosis. How is iliac vein compression syndrome caused? Next, I'd like to share my views with you.

How is iliac vein compression syndrome caused?

The main reason is due to anatomical factors. The lumbosacral vertebra is behind the left common iliac vein, and the right common iliac artery is in front. When the iliac vein is compressed by the above anatomical structure, the vein wall is repeatedly compressed and stimulated, resulting in chronic injury, adhesion and narrowing of the lumen of the left common iliac vein.

Anatomical factors the anatomical relationship between iliac artery and iliac vein is the basis of iliac vein compression syndrome. The bilateral common iliac veins converge into the inferior vena cava on the right side of the middle and lower plane of the fifth lumbar vertebrae and ascend along the spine. The right common iliac vein is almost in line with the inferior vena cava, while the left common iliac vein runs from the left side of the pelvis to the right, and is almost at right angles to the inferior vena cava before the lumbosacral vertebrae.

Mcmurrich, Erich and krumbharr respectively observed the abnormal structures in the venous cavity of a large number of cadavers without significant manifestation of left lower extremity venous disease. They found that the incidence of compression of left common iliac vein and intraluminal adhesion were 32.3%, 23.8% and 14% respectively. In 1956, may and Thurner proposed that 22% of autopsies had cristae like structures in the lumen of the left common iliac vein, which contained fibroblasts, collagen and a large number of capillaries.

matters needing attention

Light diet: ginger, pepper, mustard, garlic and all spicy hot materials will damage the pharyngeal mucosa. You should avoid these spicy and fried foods and eat more fruits and vegetables containing vitamin C. Pay attention to oral hygiene: pay attention to personal hygiene and wash hands frequently. You can gargle with light salt water in the morning and evening. After gargling, you may as well drink another cup of light salt water to clean and moisten the throat, improve the pharyngeal environment and prevent bacterial infection.
