Angiography

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.

Angiogram

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?

Diagnosticated angiography

  • 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

Chronic diseases

  • Vascular affection/tumors

Who does the intervention?

A specialist in interventional radiology

  • Peripheral angiography – diagnosed and interventional

A specialist in interventional cardiology

  • Coronarography
  • Cardiac catheterization

Diagnosed angiography

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

Visceral artery:

  • 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.

Therapeutic angiography

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.
