Sao Paulo Medical Journal = Revista... Mar 2001Many patients with intermittent claudication continue to be forwarded to the vascular surgeon for initial evaluation after arteriography has already been accomplished.
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 arteriography already performed and Group 2 without the initial arteriography.
PARTICIPANTS
One hundred patients with intermittent claudication were retrospectively studied. Other specialists had forwarded them for the first evaluation of intermittent claudication, without any previous treatment.
MAIN MEASUREMENTS
All patients were treated clinically for at least a 6-month period. The total number of arteriographies performed in the two groups was compared and the need and usefulness of the initial arteriography (of Group 1) was also analyzed.
RESULTS
The evolution was similar for both groups. The total number of arteriographies was significantly higher in Group 1 (Group 1 with 53 arteriographies vs. Group 2 with 7 arteriographies). For this group, it was found that arteriography was only useful in five cases (10%), because the surgeries were based on their findings. However, even in those cases, no need for arteriography was observed, as the procedure could have been performed at the time of surgical indication.
CONCLUSION
There are no indications for arteriography in the early evaluation of patients with intermittent claudication, because it does not modify the initial therapy, independent of its result. In cases where surgical treatment is indicated, this procedure should only be performed prior to surgery.

Coronary arteriography has evolved into a relatively safe and simple procedure, yielding important information about the patient with clinical manifestations of coronary heart disease. The clear trend is to employ arteriography earlier and more frequently in the evaluation. The major therapeutic modality dependent on arteriography at present is bypass surgery, but transluminal angioplasty is rapidly developing and will probably be applicable to an expanding portion of patients. Even newer is thrombolysis in acute myocardial infarction with its promise of limiting myocardial damage in that setting.

Comparative Study
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 that compared exclusion arteriography and surgical exploration, the standard used prior to the development of extremity arteriography. The decision model used predominantly literature derived estimates for the prevalence of arterial injuries and the accuracy, complications, outcomes and costs of both arteriography and exploration. Exclusion arteriography is cost-effective. This finding is robust to changes in the major model variables. Compared to surgical exploration, exclusion arteriography is a superior strategy by dominance (more effective and costs less). Therefore, a cost-effectiveness ratio cannot be calculated. Under the base case assumption of 28% prevalence of arterial injury requiring operation, exclusion arteriography saves about $2000 and adds 0.3 quality adjusted life years (QALY) for each patient. Decision analysis can be successfully applied to problems in vascular trauma diagnosis.

This study aims at accurate quantification of x-ray exposure and effective dose to the patient in abdominal arteriography. Using an automatic monitoring system, all relevant exposure parameters were determined during 172 abdominal arteriographies. Common projections were extracted for a 'normal' reference group of procedures and used in Monte Carlo calculations of dose-area product to organ dose conversion coefficients. Dose-area product, organ doses and effective dose were quantified for intravenous and intra-arterial procedures. The large data sets describing exposure could be condensed to a set of 28 common views. New coefficients to convert dose area product to organ equivalent dose and effective dose were calculated for nine views contributing approximately 80% to the total dose-area product. The average dose-area product was 32 Gy cm2 in intravenous procedures and 47 Gy cm2 in intra-arterial procedures. The corresponding average effective doses to the patient were 4 mSv and 6 mSv respectively (range 2-12 mSv, actual value depending on procedure type and gender). It is concluded that automatic monitoring of x ray exposure parameters, complemented by the calculation of Monte Carlo organ dose conversion coefficients, is a feasible and promising approach to accurate dosimetry of complex arteriographic procedures.
