View source for 33. Intravascular radiologic interventions I. Methods of revascularization (PTA, stent implantation, selective thrombolysis, catheter thrombectomy/embolectomy).

* 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
