Catheters. Catheters are used in many different interventional radiology procedures, and therefore come in a variety of shapes, sizes, and configurations. Broadly, catheters can be divided into two main categories: nonselective flush catheters and selective catheters.
What is IR catheter?
The Tools. Catheter: a hollow tube that can go over wires to help guide and direct them into different blood vessels or body cavities (e.g., post-operative abscess). Catheters can be used to deliver contrast/fluids, collect blood samples, or drain pathologic body fluid collections (e.g., pus, bile, blood, etc.).
What imaging is used in cardiac catheterization?
X-ray fluoroscopy (XRF) is the most commonly used imaging modality to guide transcatheter procedures.
What is the difference between a guidewire and a catheter?
The guidewire is the device used to guide the catheter into place during CVC insertions. The purpose of a guidewire is to gain access to the blood vessels using a minimally invasive technique. The stylet is used to add stiffness to the catheter during insertion. After placement, the stylet is removed from the catheter.
What are guide catheters?
Guide catheters are required for all coronary interventions to provide access to the coronary ostium and support equipment delivery. The ideal guide provides stability for device advancement through the coronary anatomy, while minimising vessel trauma and allowing for vessel opacification.
What is interventional radiology Slideshare?
INTERVENTIONAL RADIOLOGY A subspecialty which provides minimally invasive techniques with the help of imaging modalities to diagnose or treat a condition.
What does a CTA scan show?
Computed tomography angiography (CTA) uses an injection of contrast material into your blood vessels and CT scanning to help diagnose and evaluate blood vessel disease or related conditions, such as aneurysms or blockages. CTA is typically performed in a radiology department or an outpatient imaging center.
What is a CTA scan of the heart?
Coronary CT angiography (CTA) is a noninvasive test that uses X-rays in the form of computed tomography to diagnose coronary artery disease. Coronary CTA provides high-resolution images of the blood vessels supplying the heart, allowing identification of narrowing or blockages caused by plaque.
What types of catheters are there?
There are three main types of catheters: indwelling catheters, external catheters, and short-term catheters.
- Indwelling catheters (urethral or suprapubic catheters) An indwelling catheter is a catheter that resides in the bladder.
- External catheters (condom catheters)
- Short-term catheters (intermittent catheters)
What are the different types of interventional procedures?
Interventional radiologists perform a wide range or procedures, including:
- Angioplasty and Stent Insertion.
- Ascitic Tap.
- Biliary Drainage.
- Bursal Injection.
- Carotid Stenting.
- Carpal Tunnel Ultrasound and Injection.
- Image Guided Cervical Nerve Root Sleeve Corticosteroid Injection.
- Image Guided Liver Biopsy.
What are the most common interventional radiology procedures?
Common IR Procedures
- Deep Vein Thrombosis / Pulmonary Embolism.
- Peripheral Arterial Disease.
- Vascular Malformations.
- Dialysis Catheters, Venography, and Declots.
- Obstructive Nephropathy.
- Varicose Veins.
- Portal Hypertension.
What is interventional radiology and how does it work?
This short film shows what interventional radiology is: The essential skills of an interventional radiologist are in diagnostic image interpretation and the manipulation of needles and the use of fine catheter tubes and wires to navigate around the body under imaging control.
How do interventional radiologists treat arterial diseases?
Narrowing of arteries leading to restricted blood flow (peripheral vascular disease): Interventional radiologists treat this by using balloons to stretch the vessel (balloon angioplasty, PTA) and sometimes metal springs called stents to hold them open. Sometimes arteries or bypass grafts block suddenly with a rapid loss of blood supply to the limb.
How do interventional radiologists treat pulmonary embolism?
Blood clots in the lung (pulmonary embolism, PE) : interventional radiologists perform 2 different forms of treatment, placement of devices (inferior vena cava filters) to capture blood clots before they reach the lung preventing further PE.
What are Irir therapies used for?
IR therapies are used for the following: to treat the tumour / cancer (tumour ablation, embolization) to relieve the effects of the cancer on other systems e.g. blockage of the gullet (oesophagus), bowel, kidney (nephrostomy) or liver (biliary drainage) To drain collections of fluid or pus in the chest or abdomen.
