angiography

Indications

• vascular disease, especially
  • arterial thrombosis
  • vascular aneurysm
  • coronary artery disease
  • peripheral vascular disease
    • carotid artery disease

Clinical significance

limitations of angiography (carotid angiography)

• 2 dimensional display
• accuracy depends on lumenal conformation
  • round, elliptical, crescent, multilobular

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

Complications

• renal toxicity 2-5%
• cardiac toxicity (rare)
  • arrhythmias
  • decreased contractility?
• dissecting aneurysm

Management

• intravenous sodium bicarbonate &/or oral acetylcysteine of no benefit in preventing acute kidney injury

Notes

1895 contrast angiography

1920 non-toxic contrast media

1990 non ionic contrast
