Buga syndrome is a clinical syndrome of impaired organ tissue stasis caused by partial or complete obstruction of the hepatic veins or (and) the inferior vena cava of the hepatic segment, resulting in impaired venous blood return. So how should hepatic venous reflux disorder be prevented? Here is a brief introduction. Prevention of hepatic venous reflux disorder should start from the causes, pay attention to their habits, have some awareness of prevention after surgery and childbirth, patients with diseases that may cause hepatic venous reflux disorder and people with family history of the disease should be alert. Only by raising awareness of prevention, early detection and early treatment is the best way to reduce the harm of hepatic venous reflux disorder. For the treatment of hepatic venous reflux disorder, experts recommend patients to use “interventional therapy”, which is an interventional stenting treatment that can be performed under the DSA angiography system by making a small percutaneous incision of two millimeters, introducing a catheter into the lesioned vessel, and placing a stent to expand the narrowed and blocked area and restore blood flow to achieve The purpose of treatment is to restore blood flow to the stenotic area. Interventional therapy is an emerging medical technology in recent years, and is the third major clinical treatment system alongside internal medicine and surgery. As an analogy, the blood vessels in the human body are like the sewers in the city, which are connected to every organ of the body in all directions. Interventional therapy is the use of high-tech digital subtraction imaging equipment to guide micro-catheters from a 2mm incision in the skin to penetrate into the patient’s blood vessels at the lesion site for treatment, so interventional therapy is also known as surgery without incision. It has precise treatment, small trauma, fast results and few complications.
