Orbital varicose veins

Varicose veins (varix, varicocele) are common venous malformations that occur in the orbit, accounting for 6.3% of orbital diseases. A regular cystic dilation of a vein is called varix, and if the vein is irregularly dilated, it is called varicocele. It can be cystic or polycystic. The lesion is composed of one or more veins or cystic dilatation. The lesion often surrounds the normal structure of the orbit, such as the optic nerve and extraocular muscles. Vascular lumen is large and thin-walled, and larger vessels contain elastic fibers. Thrombosis can be seen in malformed blood vessels, leading to thrombosis, which then calcifies and eventually forms phleboliths. Some scholars regard varicose veins and venous malformations as synonyms. In fact, in addition to varicose veins, orbital venous malformations also include venous hemangioma. Varicose veins are clinically used disease names. Sinusitis is often caused by sinus opening deformities. Inflammation of the orbital soft tissues can also cause intermittent eyeball protrusions. The orbital wall is missing and eyeball protrusions occur when you lower your head. Are not equal. From a clinical and pathological point of view, it can be defined as follows: ① malformed blood vessels are composed of veins of different sizes, and the input and output blood vessels are veins; ② the malformed blood vessels lack or have few fibrous tissue connections; ③ clinically orthopedic Eyes are prominent. Varicose veins are not uncommon in orbital occupying lesions. Because pathological biopsy specimens are rarely obtained, the actual incidence is higher than reported in the literature.
