Neuroradiologic applications of intraarterial digital subtraction angiography.

In the neuroradiologic evaluation of 118 patients using intraarterial digital subtraction angiography definite advantages and disadvantages were defined. Advantages include reduction of contrast medium volume, catheter time, and patient risk and discomfort. It also aids in angiographic planning. The paramount disadvantage is less spatial resolution compared with conventional film angiography.

Vascular Intervention Carbon Dioxide Digital Subtraction Angiography for A Renal Artery Stent Placement 1

MATERIALS AND METHODS: Seventeen hypertensive patients with renal ostial stenosis were evaluated and underwent stent placement with use of CO, digital subtraction angiography (DSA). Besides hypertension, 11 patients had decreased renal function, three had iodinated contrast material allergy, one patient had both, and two had neither.

Carbon dioxide digital subtraction angiography-assisted endovascular aortic aneurysm repair in the azotemic patient.

OBJECTIVE This report analyzes the safety and efficacy of carbon dioxide digital subtraction angiography (CO(2)-DSA) for EVAR in a group of patients with renal insufficiency compared with a concurrent group of patients with normal renal function undergoing EVAR with iodinated contrast angiography (ICA). METHODS Between 2003 and 2005, 100 consecutive patients who underwent EVAR using ICA, CO(2...
