18 Mar 2011 Many workhorse guide wires are indicated to facilitate the placement of balloon dilatation catheters during percutaneous transluminal coronary angioplasty (PTCA) and The wires are sometimes hard to see on fluoroscopic X-ray imaging, so radiopaque markers are commonly used to improve visibility.
Given the breadth of procedures, complexity, variability in anatomy, and vascular approach in the periphery, there are a plethora of available wires, introducer sheaths, and delivery, diagnostic, and interventional guiding catheters. Many of the available devices are shown in Tables 6 and 7 (see p. 48 and 49).

Interventional radiology (IR), sometimes known as vascular and interventional radiology (VIR), is a medical specialty which provides minimally invasive image-guided diagnosis and treatment of disease. Although the range of procedures performed by interventional radiologists is broad, the unifying concept behind these
31 Jul 2015 Guide wires are used for both Cardiology and Radiology angiographic procedures. 4. Guide 22 DEFINITION : A catheter is a hollow flexible tube that can be inserted into a body cavity, duct or vessel. Tunnelled Catheters –They can be accessed externally and are designed for long term home use.

When deciding between these modalities, the interventional radiologist must balance the type of procedure, individual patient characteristics, and the advantages and disadvantages of each modality. The fundamental endovascular equipment includes guidewires and catheters, but a slew of other endovascular devices
23 Dec 2015 The basic principles of vascular access and catheter guidewire manipulation for selective and superselective angiography were described over a half of translumbar access needles as interventional rather than diagnostic tools.8,9 The needles are also used to provide transhepatic access for long-term
19 Jan 2015 The full online presentation provides a pictorial guide that showcases the basic needles, wires, catheters, and sheaths used in interventional radiology (Figs 1, 2) and describes their identifying features and nomenclature. Wires are described according to their diameter, stiffness, and hydrophilic or
