Minimally noninvasive treatment of neurological vascular disease
Neurointerventional radiology and interventional radiology are subspecialties of diagnostic radiology that encompasses the diagnosis of all abnormalities and anomalies of the arteries, veins, and lymphatics. It includes all vascular and nonvascular imaging-directed interventional procedures. All modalities and techniques used in diagnostic and interventional procedures are also part of this subspecialty.
Neurointerventional radiology is directed towards the minimally noninvasive treatment of neurological vascular disease, including aneurysms and AVMs. Interventional radiology is directed towards the minimally invasive treatment of cancer, vascular disease, vascular malformations and medical conditions including diseases of the liver, kidneys and solid organs.
Radiologists perform a number of minimally invasive procedures that provide patients with options to traditional surgical techniques for a variety of conditions:
- Aneurysm and AVM embolization is a minimally invasive way of treating vascular malformations of the brain and spine
- Tumor ablation is used to eliminate tumors in organs like the liver, lung and kidneys
- Angioplasty is a way of opening a narrowed or closed blood vessel without having to do major surgery
- Embolization, a fairly new treatment method, is a way of closing -- or at least drastically reducing -- blood flow through one or more blood vessels that are associated with disease
- A vascular access procedure is designed for patients who need intravenous access for a considerable time, longer than 10 days to two weeks
- The transjugular intrahepatic portosystemic shunt (TIPS) procedure is used for the treatment of abdominal fluid accumulation and life threatening bleeding into the bowel
