Solar plexus vascular varicose is generally considered to be related to intracranial hypertension, temporal arteritis, vascular malformation. 1. Intracranial hypertension: various causes of intracranial hypertension, such as intracranial venous sinus thrombosis, intracranial infections, tumors, hydrocephalus, etc., can lead to intracranial hypertension, affecting intracranial venous reflux, which can lead to the manifestation of varicose veins in the temples. 2. Temporal arteritis: also known as giant cell arteritis, is a kind of chronic, granulomatous inflammation of the whole layer of the arteries that occurs in the elderly, and the etiology is not known. The superficial temporal artery is thickened, hardened, nodular and painful; occasionally, the posterior occipital, facial and posterior auricular arteries may also be involved. 3. Vascular malformation: If the temporal artery has an arteriovenous fistula, localized vascular varicose can also be seen. When varicose veins in the temples are accompanied by headache or other uncomfortable symptoms, it is recommended to consult a doctor in time to further clarify the cause of the disease.
