Endovascular surgery is a modern approach to vascular pathology through minimally invasive techniques. This represents an enrichment of the arsenal of surgical techniques and brings considerable improvements in post-operative and long-term results. At the same time, it allows the approach of vast vascular territories, often inaccessible to conventional surgery.
An endovascular specialist can detect liver cancer, among other medical conditions, before it causes too many problems. Moreover, it can intervene in the treatment, through arterial embolization, radio-embolization and chemoembolization.
The liver is an unusual organ, in the sense that it has two sources of blood supply. Liver cells are being fed by the portal vein, while cancer cells are fed by the hepatic artery. Blockage of the hepatic artery supplying the tumor may help to destroy cancer cells and does not affect healthy cells, since they have another source of supply – the portal vein.
Embolization in liver cancer is the procedure by which an endovascular specialist injects substances that block or reduce blood circulation to cancer cells in the liver.
According to a well known liver cancer specialist in Phoenix, this technique can be combined with chemotherapy and radiation therapy.
Possible complications of embolization include abdominal pain, nausea, liver infections, inflammation of the gallbladder and blood clots in the main blood vessels of the liver. Since healthy tissue can be affected by embolization, there is a risk of deterioration of liver functions. Severe complications are not frequent, but they are possible.
