Angiography is imaging of the blood vessels (arteries or veins). This common procedure is performed by the specially trained radiologist and its purpose is to look for any vascular abnormality such as aneurysms, arteriosclerotic disease or to evaluate vascular supply to tumors. Sometimes the study is done to evaluate normal anatomy in the setting of pre surgical planning or organ transplant.
Angioplasty is insertion of balloon catheter into a narrowed blood vessel. The balloon is inflated for a few seconds dilating the vessel and restoring the blood flow.
a vascular stent is sometimes after dilatation, the blood flow is still inadequate and metallic prosthesis needs to be inserted into the vessel in order to keep it open. These procedures are performed by the specially trained radiologist or vascular surgeon who will discuss the options with you.
Embolization is an interventional vascular procedure used to block abnormal artery or vein; it is achieved by placing the thin plastic tube (angiographic catheter) selectively into the vessel and administering appropriate embolization material. Embolization is much less invasive than open surgery with fewer complications and shorter hospital stay.
Arterio-venous shunt is a surgically created connection between the artery and vein – most often in your forearm or upper arm. It provides easy access for procedure called hemodyalysis in people whose kidneys have failed.
