  • Percutaneous transluminal angioplasty
    • Indications
      • Coronary artery disease
      • Peripheral artery disease
    • A deflated balloon attached to a catheter is passed into a narrowed vessel
    • -> the balloon is inflated -> opens the vessel
    • A stent can be placed where the vessel was narrowed to keep it open
    • Stent can be made of
      • Steel
      • Gold
      • Nickel-titanium
      • (NOT wolfram)
  • Selective thrombolysis/fibrinolysis
    • A catheter is directed close to a thrombus
    • Fibrinolytics are ejected through the catheter, lysing the thrombus
  • Catheter thrombectomy/embolectomy
    • A catheter is directed to a thrombus and removes it
  • Transjugular intrahepatic porto-systemic shunt (TIPS)
    • Treats portal hypertension
    • A shunt is made between a hepatic vein and portal vein, allowing some portal blood flow to bypass the liver
      • This decreases portal hypertension
