angiography
Indications:
- vascular disease, especially
- arterial thrombosis
- vascular aneurysm
- coronary artery disease
- peripheral vascular disease
- carotid artery disease
Procedure:
- a method of visualizing blood vessels by introducing a radiographic solution, generally by percutaneous catherization of an artery or vein & placement of the tip of the catheter under fluoroscopic control
Clinical significance:
limitations of angiography (carotid angiography)
1) 2 dimensional display
2) accuracy depends on lumenal conformation
- round, elliptical, crescent, multilobular
Complications:
1) renal toxicity 2-5%
2) cardiac toxicity (rare)
a) arrhythmias
b) decreased contractility?
3) dissecting aneurysm [2]
Management:
- intravenous sodium bicarbonate &/or oral acetylcysteine of no benefit in preventing acute kidney injury [3]
Notes:
1895 contrast angiography
1920 non-toxic contrast media
1990 non ionic contrast
