Numerous tools are at the disposal of modern vascular and interventional radiologists to perform these procedures, and developing new tools is a burgeoning focus of international research. While some interventional radiology endovascular procedures are highly specialized, a few standard techniques apply to most:
Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...
The vascular surgeon has several modalities to treat lower extremity venous disease which including medical, interventional and surgical procedures. For instance, venous ulceration may be treated with Unna's boots, superficial venous reflux with radiofrequency, laser ablation or vein stripping if indicated. When indicated, insufficiency in the ...
Percutaneous intentional extraluminal revascularization is a percutaneous technique used in interventional radiology for limb salvage in patients with lower limb ischemia due to long superficial femoral artery occlusions. This method is intended for those patients who make poor candidates for infrainguinal arterial bypass surgery. [1]
With the introduction of the Seldinger technique in 1953, the procedure became markedly safer as no sharp introductory devices needed to remain inside the vascular lumen. Radial access technique for angiography can be traced back to 1989, when Lucien Campeau first cannulated the radial artery to perform a coronary angiogram.
The Seldinger technique, also known as Seldinger wire technique, is a medical procedure to obtain safe access to blood vessels and other hollow organs. It is named after Sven Ivar Seldinger (1921–1998), a Swedish radiologist who introduced the procedure in 1953.
Intravascular imaging is a catheter based system that allows physicians such as interventional cardiologists to acquire images of diseased vessels from inside the artery. . Intravascular imaging provides detailed and accurate measurements of vessel lumen morphology, vessel size, extension of diseased artery segments, vessel size and plaque characteristi
Transcatheter arterial chemoembolization (TACE) is a minimally invasive procedure performed in interventional radiology to restrict a tumor's blood supply. Small embolic particles coated with chemotherapeutic drugs are injected selectively through a catheter into an artery directly supplying the tumor.
