a subspecialty of radiology in which
minimally invasive procedures are
performed using image guidance
Interventional Radiology
An ____ is a scan that shows blood flow
through arteries or veins, or through the heart, using X-rays, computed tomography angiography (CTA) or
magnetic resonance angiography (MRA). The blood vessels appear on the image after a contrast dye is injected into the blood, which lights up on the scan wherever it flows
angiogram
is a treatment that uses stents to improve blood flow to the heart by opening a narrowed or blocked coronary artery
Angioplasty
is a palliative treatment for liver cancer. This can be a cancer originating in the liver or a cancer that has spread (metastasized) to the liver from other areas of the body. During chemoembolization, three chemotherapy drugs are injected into the artery that supplies blood to the tumor in the liver. The artery is then blocked off (embolized) with a mixture of oil and tiny particles
Chemoembolization
The gallbladder was identified by ultrasound and, under aseptic condition, aSeldinger needle was passed through the parenchyma of the liver to reach the gallbladder. Initially, the fluid aspirated from the gall bladder
was collected and sent for bacteriologic analysis. Then, pigtail catheter (of
8F size) was inserted under sonographic guidance through a 2-step
technique that included the exchange of guide-wire
PERCUTANEOUS CHOLECYSTOSTOMY
involves placing a hollow plastic tube
between the ribs and into the chest to drain fluid or air from around the lungs. The tube is often hooked up to a suction machine to help with drainage. The tube remains in the chest until all or most of the air or fluid has drained out, usually within a few days
Chest tube thoracostomy
The gallbladder was identified by ultrasound and, under aseptic condition, aSeldinger needle was passed through the parenchyma of the liver to reach the gallbladder. Initially, the fluid aspirated from the gall bladder
was collected and sent for bacteriologic analysis. Then, pigtail catheter (of
8F size) was inserted under sonographic guidance through a 2-step
technique that included the exchange of guide-wire
PERCUTANEOUS CHOLECYSTOSTOMY
is a minimally invasive treatment that blocks one or more blood vessels or abnormal vascular channels. In a catheter embolization procedure, medications or synthetic materials called embolic agents are placed
through a catheter into a blood vessel to prevent blood flow to the area
CATHETER EMBOLIZATION
is a procedure used to break up
abnormal blood clots that restrict blood flow in veins and arteries
Thrombolysis
is a minimally invasive treatment that blocks one or more blood vessels or abnormal vascular channels. In a catheter embolization procedure, medications or synthetic materials called embolic agents are placed
through a catheter into a blood vessel to prevent blood flow to the area
CATHETER EMBOLIZATION
uses soundwaves to help locate a lump
or abnormality and remove a tissue sample for examination under a
microscope. It is less invasive than surgical biopsy, leaves little to no
scarring and does not involve exposure to ionizing radiation
ultrasound-guided biopsy
is a minimally invasive technique that shrinks the size of tumors, nodules or
other growths in the body. RFA is used to treat a range of conditions, including benign and malignant tumors, chronic venous insufficiency in the legs, as well as chronic back and neck pain
Radiofrequency ablation or RFA
is a type of cryotherapy, a minimally invasive interventional radiology
procedure that uses extreme cold to freeze and kill abnormal cancerous and precancerous cells. The application of cold to tumor cells prevents further growth or spreading, making this an effective outpatient treatment for
cancer
Cryoablation
is a type of cryotherapy, a minimally invasive interventional radiology
procedure that uses extreme cold to freeze and kill abnormal cancerous and precancerous cells. The application of cold to tumor cells prevents further growth or spreading, making this an effective outpatient treatment for
cancer
Cryoablation
is a type of cryotherapy, a minimally invasive interventional radiology
procedure that uses extreme cold to freeze and kill abnormal cancerous and precancerous cells. The application of cold to tumor cells prevents further growth or spreading, making this an effective outpatient treatment for
cancer
Cryoablation
is an indwelling device inserted into a large, central vein (most commonly the
internal jugular, subclavian, or femoral) and advanced until the terminal lumen resides within the inferior vena cava, superior vena cava, or right atrium
central venous catheter (CVC)
is a small device that can stop blood clots from going up into the lungs. The inferior vena cava is a large vein in the middle of your body. The device is
put in during a short surgery
inferior vena cava (IVC) filter
is a procedure in which a special cement is injected into a fractured
vertebra — with the goal of relieving your spinal pain and restoring your mobility
Vertebroplasty
is a procedure to drain urine from your kidney using a catheter (tube). Urine normally drains from your kidneys into your bladder through small muscular
tubes (ureters)
nephrostomy
is a procedure where a tube is
inserted percutaneously into the stomach, principally to provide nutritional support for patients with swallowing disorders
radiologically inserted
gastrostomy (RIG)
is a procedure to remove waste
products and excess fluid from the blood when the kidneys stop working properly. It often involves diverting blood to a machine to be cleaned
Dialysis
is a shunt or a bypass use to connect two veins within the liver with the use of x-ray by interventional radiology. This tract is what we call a Transjugular Intrahepatic Portosytemic Shunt or simply abbreviated as TIPS
Transjugular Intrahepatic Portosystemic
Shunt (TIPS)
is a shunt or a bypass use to connect two veins within the liver with the use of x-ray by interventional radiology. This tract is what we call a Transjugular Intrahepatic Portosytemic Shunt or simply abbreviated as TIPS
Transjugular Intrahepatic Portosystemic
Shunt (TIPS)
are minimally invasive
procedures that treat bile ducts that are
blocked, narrowed, or injured and
gallbladders that are inflamed or infected
Biliary interventions
