Effective Treatment Of Vascular Lesions Can Be Found Through Embolization
Embolization refers to a non-surgical procedure that is performed by an interventional radiotherapist and interventional neuroradiologists. This minimally-invasive procedure involves the selective occlusion of blood vessel by injecting emboli. The purpose of embolization is to block the blood flow in the affected area that can shrink a tumor or affected cells. The vascular lesion indicates to the abnormal tissue on the vascular region caused by injury or disease. It maybe of both kinds either benign (noncancerous) or malignant (cancerous).
The patient who undergoes vascular embolization or vein embolization is usually given a general anesthetic. With the help of digital subtraction angiography (DSA), physicians can find the position of the correct artery or vein for the supply of pathology. These images can be used as a map for the radiologist to gain access to the exact vessel for the injection of catheter or wire. There are some artificial emboli that have been successfully introduced. Some of the important agents of embolization are liquid embolic agents, ethiodol, sclerosing agents, ethanolamine oleate, sotradecol, gelfoam, polyvinyl alcohol, mechanical occlusion devices, coils, detachable balloon etc.
Catheter embolization is performed to control or prevent abnormal bleeding that result from an injury, tumor or gastrointestinal tract lesion. Use of embolization for Vascular Lesions is very fruitful to check the blood flow in the multiple vessels. The lesion can be removed by light absorbed by the blood. Laser therapy is a safe and secure treatment that produces gradual results. The discoloration cause by laser can last anywhere from 5 to 14 days depending on the location, size and type of the lesion being treated. The equipments involved in the treatment consist of the radiographer table, x-ray tube and a computer system to monitor the diagnosis procedure.
