Arterial embolization

Arterial embolization is an interventional radiology procedure in which agents are deposited in arteries to block blood flow, used to stop hemorrhage, treat aneurysms and arteriovenous malformations, and infarct tumors such as hepatocellular carcinoma.

Balloon-occluded retrograde transvenous obliteration

Balloon-occluded retrograde transvenous obliteration (BRTO) is a percutaneous procedure that treats gastric fundal varices in portal hypertension, introduced by Hiroshi Kanagawa in 1996 as an alternative to TIPS.

Cementoplasty

Cementoplasty, also known as percutaneous cementoplasty, is a percutaneous procedure that injects acrylic bone cement into malignant bone cavities to relieve pain and stabilize bone.

Hepatic artery embolization

Hepatic artery embolization, also called bland transarterial embolization, is an interventional radiology procedure that blocks arterial blood flow to kill liver tumors that cannot be surgically removed.

Interventional Magnetic Resonance Imaging

Interventional MRI (iMRI, MR-guided interventional procedures): minimally invasive procedures guided by magnetic resonance imaging, emerging in the late 1980s; used for breast/prostate biopsy, tumor ablation, and cardiac procedures; no ionizing radiation but RF-heating and access challenges.

Interventional radiology

Interventional radiography (interventional radiology, IR): image-guided minimally invasive procedures using fluoroscopy, CT, and ultrasound. Founded on Seldinger's 1953 technique and Dotter's 1964 angioplasty; evolved from diagnostic angiography to a therapeutic clinical specialty.

Interventional Ultrasonography

Interventional ultrasonography (interventional ultrasound): diagnostic and therapeutic procedures such as biopsy, drainage, catheterization, and ablation performed under real-time ultrasound guidance; first introduced in Europe, 1972 first clinical use, low complication rates.

Percutaneous transhepatic biliary drainage

Percutaneous transhepatic biliary drainage (PTBD) is an image-guided procedure in which a catheter passed through the skin and liver drains bile, relieving biliary obstruction when ERCP is unsuitable.

Portal vein embolization

Portal vein embolization is a percutaneous radiology procedure that blocks portal vein branches to the liver segments to be resected, causing the future liver remnant to grow before major hepatectomy.

Radiation segmentectomy

Radiation segmentectomy is a liver-directed radioembolization technique that delivers ablative yttrium-90 microsphere doses to one or two hepatic segments, most often to treat solitary hepatocellular carcinoma.

Uterine artery embolization

Uterine artery embolization is an interventional radiology procedure in which particles block blood flow in both uterine arteries, shrinking fibroids as a uterine-sparing alternative to hysterectomy and controlling postpartum hemorrhage.
