Arteriography

Sensitivity of superselective arteriography for small hepatocellular carcinoma compared with proximal arteriography and computed tomography during superselective arteriography.

PURPOSE To obtain successful arterial chemoembolization for hepatocellular carcinoma (HCC), we evaluated the sensitivity of proximal arteriography, superselective (subsegmental or more distal branch) arteriography and computed tomography (CT) during superselective arteriography and assessed the method for the injection of contrast medium. METHODS Thirty-two patients with 38 HCCs (< or = 5 cm)...

The cost-effectiveness of exclusion arteriography in extremity trauma.

The purpose of this study was to apply decision analysis to an established practice in vascular trauma diagnosis. While exclusion arteriography has resulted in an increase in positive surgical explorations, no formal analysis that determined either the cost-effectiveness of exclusion arteriography or the cost-effectiveness ratio has been reported in the literature. We created a decision model t...

Proximity arteriography: cost-effectiveness in asymptomatic penetrating extremity trauma.

PURPOSE Many urban trauma centers have abandoned proximity arteriography, which is defined as exclusion arteriography used to evaluate the asymptomatic patient with penetrating extremity trauma near major arteries. However, decision analysis has not been applied to study proximity arteriography. MATERIALS AND METHODS The cost-effectiveness of proximity arteriography was examined by creating a...

New guidelines for drive-by renal arteriography may lead to an unjustifiable increase in percutaneous intervention.

Delayed cerebral ischemia following arteriography.

Cerebral ischemic events associated with arteriography are usually attributed to catheter-induced emboli. We present three patients with cerebral ischemia occurring 6 to 48 hours post-arteriography. We suspected that alternate pathogenic mechanisms were in effect. To evaluate the possibility that sustained platelet activation occurs in association with arteriography, we measured the platelet-sp...

Use of arteriography for the initial evaluation of patients with intermittent lower limb claudication.

CONTEXT Many patients with intermittent claudication continue to be forwarded to the vascular surgeon for initial evaluation after arteriography has already been accomplished. OBJECTIVE The main objective of this work was to analyze the usefulness and the need for this procedure. TYPE OF STUDY Retrospective study. SETTING The patients were divided into two groups: Group 1, with the arteri...
