Angiography is a painless, minimally invasive non-surgical intervention, which is made with X rays to view internal layout of the blood vessels of the limbs, internal organs or heart.
An angiogram represents the sum of the X ray images recorded throughout the passage of iodinated contrast agent investigated by sector (aa-vv/cord):
- Morfo-functional aspects
- Hospitalization only
- Angiographic techniques may be considered routine exams only in laboratories equipped with specific equipment and well trained staff!
- Extremely fast development between 1980 – 2000
How it’s made?
SELDINGER technique – local or general anesthesia
- Tran lumbar approach
- Femoral approach
- Brachial approach
- Radial approach
When does angiography apply?
- Vascular affections
- Different types of tumors
Acute diseases / emergency
- Digestive or cerebral hemorrhage
- Retreatment cerebral aneurysms
- Polytraumatism – visceral or upper/lower limb
- Embolism/thrombosis acute
- Vascular affection/tumors
Who does the intervention?
A specialist in interventional radiology
- Peripheral angiography – diagnosed and interventional
A specialist in interventional cardiology
- Cardiac catheterization
Upper / lower limbs - arterial occlusive diseases - may be completed by dilating stenosis + / - stenting.
Aortography - to view the thoracic/abdominal aorta branches
Carotid artery - useful for the interventional diagnosis and possible treatment (dilatation, stent implantation) of carotid stenosis responsible for strokes.
Cerebral arteries - the diagnosis of intracranial vascular malformations
- Mesenteric artery - diagnosis and treatment of acute gastrointestinal bleeding
- Kidney - diagnosis, treatment of renal stenosis in hypertension
- Celiac - hepatic - splenic trunk - diagnosis and treatment of bleeding, liver cancer and traumatic pathology.
Digestive embolization – stops the digestive bleeding (angiodisplasty, arteriovenous malformations) by endovascular treatment.
Dilatation of arterial stenosis - balloon dilatation / stenting of arterial stenosis of the upper or lower limbs, renal artery, celiac trunk, superior or inferior mesenteric artery
Endovascular therapy in ischemic stroke and also endovascular treatment of non-surgical carotid stenosis
VCI filter implantation – to prevent pulmonary tromboembolism
Uterine embolization - non-surgical interventional treatment of uterine fibroids
Interventional treatment in primary and secondary liver tumors as in:
- chemoembolization: hepatic artery injection of cytostatics and emboligen material (helps to reduce the vascularization of tumors)
- chemotherapy infusion: injection of cytostatics, without emboligen material
Axillary or subcutaneously implantation of a reservoir for chemotherapy. The reservoir is implanted by an interventional method by which cytostatic drugs are injected into the tank directly into hepatic artery.
