Cellular changes in the veins are the absence of the inherent internal structure of the veins in the organ, which is manifested as internal changes in the form of a honeycomb on ultrasound, CT, and other imaging tests, i.e., phlebitis. The formation of honeycomb changes in the blood vessels will affect the normal circulation of blood, resulting in the direction of blood flow is no longer consistent, the blood in the operation of the smoothness of the blood will be reduced, and further will be prone to lead to blood clots, rupture of the blood vessels, and other abnormal manifestations. The initial stage of the disease is not too serious, but if you do not pay attention to it, the progression of the disease will have an impact on the function of the organs in which it is located, such as the liver and the gastrointestinal tract. Therefore, it is important to review the condition regularly and to treat it surgically if it progresses or if there is a risk of thrombosis or rupture of the vein. In addition, in the case of infection in a vein-rich area, the veins are dilated, and ultrasound shows honeycombing of the veins, and there may be other manifestations of the infection, such as fever, pain, etc. After treatment of the infection, these manifestations may subside. These symptoms will disappear after the infection subsides with treatment.
