When you've achievedvascular access, it pulses, and pulses...

and pulses and pulses and pulses...Introducing the Arrow-Fischell EVAN­Ergonomic Vascular Access Needle.

Now arterial catheterization can be madesignificantly safer-with a unique new needlefrom Arrow.

The EVAN needle both indicates positiveplacement and contains the blood within aspecially engineered sealed capillary chamber.It allows you to see a pulsing column of bloodwithout letting any escape.

The body of the EVAN needle is pencil-thinand contoured for easy handling. A45° bevelat the front of the handle coincides with theangle of the needle bevel. You'll fmd that itimproves control of the needle and aidsplacement into the artery.

After needle placement is confmned, aguide wire can be simply inserted through thebuilt-in hemostasis valve and on through theneedle into the vessel. Then catheter or sheathplacement over the guide-wire can continue inthe normal fashion.

The EVAN needle is just one of the wayswe're making catheterization easier on everyone.For more information on this, or any of the newArrow International Inc. interventional procedureproducts, call 800 538-2317 and ask for Tina.

decision about the existence of a real or perceived conflict ofinterest. When, for a given author, the Editor determinesthat a situation of real or perceived conflict may exist, theauthor will be so identified with an asterisk by his/her nameon the first page of the published paper.

MANUSCRIPTPREPARATIONOriginal writings will be accepted only with the understand­ing that they are contributed solely to JVIR. Manuscriptsshould be typewritten and double- or preferably triple­spaced (all pages) on only one side of the paper with at least3-cm margins. If the manuscript is produced using a dotmatrix printer, appropriate steps should be taken to assurelegibility (eg, printers could be set in the double-strikemode). Each manuscript component should begin on a newpage in this order: Title page, Abstract, Text, Acknowledg­ments, References, Tables (each on a separate page), andCaptions for illustrations. The title page and abstract pageshould not be numbered. Sequential numbering shouldbegin with the Introduction. Four copies of the manuscriptand four complete sets of mounted figures should be sub­mitted. Because accepted manuscripts will not be returned,the author should retain a copy. Receipt of each manuscriptis acknowledged; please allow 10-15 days from the time youmailed the manuscript for receipt of an acknowledgment.

TITLE PAGEThis page should include: (1) the full title ofthe manuscript;(2) the first names, middle initials, last names, and degreesofall authors; (3)the name and street address (not P.O. box)ofthe institution from which the work originated; and (4) thecomplete name, address, zip code, telephone number, andFax number ofthe corresponding author. In the event thata manuscript is identified on its title page or in its content ashaving emanated from a particular institution, it will beassumed that the requisite approval of that institution hasbeen obtained by the authors. If the paper has been pre­sented at an SCVIR meeting or has been accepted forpresentation at an SCVIR meeting, a statement to thateffect including the year ofpresentation should be providedat the bottom ofthe title page. A blind title page (without theauthor names) should be included with each copy of themanuscript for use in the review process.

ABSTRACTAbstracts are required for all major papers. Technical notes,case reports and Interventional Radiology Rounds have noabstract. The abstract should be no longer than 1 and one­half type written pages (approximately 150 words) andshould be organized into four paragraphs.

PURPOSE: Outline the goal or objective ofthe manuscriptincluding the specific hypothesis under examination. The

purpose should also be reflected in the title of the manu­script.

MATERIALS AND METHODS: Briefly and succinctlydescribe the experimental methods, including what wasdone and how the data were collected and analyzed.

RESULTS: Findings should be presented here. Whatobservations were made? Include as much specific data aspossible includingPvalues and other indicators ofstatisticalsignificance.

CONCLUSIONS: The conclusions should flow directly andlogically from the information presented in the abstract.Emphasize here what you want the reader to retain as themajor conclusion of your study.

NOTE: Unstructured abstracts may be used for reviewarticles, including Partners in Patient Care.

KEYWORDSBelow the abstract, three to six key words derived from theRSNA Index to Imaging Literature should be listed. For casereports and technical notes (no abstract required) the keywords should be on a separate page. The key words willassist the indexers who must classify the paper underspecific subject headings.

TEXTThe text of a clinical or laboratory manuscript contains aseries ofsections that follow the title page and abstract. Theheadings of these sections are Introduction, Methods, Re­suIts, and Discussion. Lengthy papers may require subhead­ings within some sections to clarify their content.

Introduction: This section should (1) adequately but notextensively (ie, using strictly pertinent references only)describe the background information, experience, and lit­erature leading up to the present study, and (2) clearly statethe purpose of the study.

Methods: Selection of animal or human subjects shouldbe described clearly. Details of materials (includingmanufacturer's name and location [city and state] in paren­theses) and methods should be presented in sufficient detailto enable readers to reproduce the study. References shouldbe made to established methods that have been published,with particular emphasis on those that are not well known.New or substantially modified methods should be described,supported with rationale, and critically evaluated for realand potential limitations. Numbers of observations andstatistical significance of the methods should be reportedwhere appropriate. Detailed statistical analyses andmathematical derivations may sometimes be suitably pre­sented in one or more appendices.

The advantages of the Vena

" .filter..have always

been obvious: effective clot trap­ping, an unmatched combinationof PE prevention and patency,

and safe, sure deployment, just to

name a few.

Now for a few facts that haven't

been as well known:

~ Five independentscientific studies confirm the effectivenessoJthe Vena Tech-LGMfilter. Over 500patients in twenty-nine hospitals have

been studied to demonstrate the filter'ssafety and efficacy.

~ The Vena Tech-LGMfilter has been cleared Jor use since March1989. More than 1,000 physicians inNorth America have relied on the VenaTech-LGM filter since its introduction.

With the Vena Tech-LGM filter, you can

offer your patients proven protection

against life-threatening recurrent PE.

IIIIIl The filter design isunchanged. Everything that makes theVena Tech-LGM filter so highly effective ­

its conical shape, stabilizing legs and self­centering design - is the same. And ours isthe only filter that offers a choice of threecomplete placement kits, for femoral,jugu­lar, or dual access.

I:I!III The Vena Tech-LGMfilter is easier than ever to place. Its low

profile and percutaneous insertion provide

a safe, simple implantation procedure. And

we've increased the wall thickness of our

sheath by 0.15mm, facilitating placement

in patients with tortuous venous anatomy.

objectively. That's why we're com­

mitted to financially supporting the filterregistry proposed by SCVIR.

tioning into subheadings, the precise divisions should becarefully considered. In general, each division should be ofsufficient independent importance that (1) separate obser­vations or data points will be recorded for that subheadingin the Results section, or (2) it requires separate treatmentin the Discussion section of the manuscript.

Manuscripts reporting research involving human sub­jects must include a statement in the Methods sectionindicating approval by the institutional review board andnoting that informed consent was obtained from each pa­tient. Manuscripts reporting research involving animalsmust include a statement in the Methods section that eitherthe protocol was approved by the institutional animal carecommittee or that the animal care complied with the "Prin­ciples of Laboratory Animal Care" (formulated by the Na­tional Society for Medical Research) and the "Guide for theCare and Use of Laboratory Animals" (NIH Publication No.80-23, revised 1985).

Results: All data and observations should be reported inlogical sequence in the text, tables, and illustrations. Do notrepeat in the text all the data in the tables and/or illustra­tions; summarize only important observations. Complexreports may require subheadings in the Results section. Ingeneral, these subsections parallel subsections of methods.Only data and observations relevant to the individual sub­section should be included in each one. Repetition of resultsreported in other subsections should be avoided.

Discussion: Emphasize the new and important aspectsof the study and conclusions that follow from them. Do notrepeat in detail the data given in the Results section. Includein the Discussion the implications ofthe findings and theirlimitations, and relate the observations to other relevantstudies. Link the conclusions with the goals ofthe study, butavoid unqualified statements and conclusions not supportedcompletely by the data. Avoid claiming priority and alludingto work that has not been completed. State new hypotheseswhen warranted, but clearly label them as such. Recommen­dations, when appropriate, may be included.

REFERENCESNumber the references consecutively in the order in whichthey are first mentioned. The abbreviations used for periodi­cals cited in the references should follow the style of IndexMedicus. For journal articles, list surnames and initials ofall authors when six or less, such as:

1. Graham DJ, Alexander JJ. The effects of thrombin onbovine aortic endothelial and smooth muscle cells. J VascSurg 1990; 11:307-313.

When seven or more authors are listed, only the firstthree names need to be identified, followed by "et aI," such as:

1. Patchell RA, Tibbs PA, Walsh JW, et al. A randomizedtrial of surgery in the treatment of single metastases tothe brain. N Engl J Med 1990; 322:494-500.

Abstracts, editorials, and letters to the editor should benoted as such. In the case ofbooks, the authors of a chapter,title of the chapter, editor(s), title of the book, edition, city,publisher, year, and specific pages must be provided.

Please be sure that all documentation is accurate.

TABLESTables should be referred to in the text, numbered sequen­tially in Arabic numerals, and have a title. All abbreviationsused in the table should be explained in a footnote.

Tables should be presented in the style used in theJournal. No vertical lines or shading should be included.Avoid excessive use of horizontal lines within the table.

ILLUSTRATIONSIllustrations should be limited to those required to show theessential features described in the paper. Unretouched glossyprints no larger than 20 x 25 cm (8 x 10 in) are desirable.Prints to be combined into one cut, such as anteroposteriorand lateral views, should be the same height to facilitatereproduction. A tissue or transparent overlay may be used todesignate the significant points of the illustrations. Draw­ings and charts should be rendered professionally in Indiaink on white paper.

All photographs and drawings must be numbered and thetop indicated on the back. For protection against loss ordamage, each figure should then be neatly attached to paper(one illustration per page) and the number and top should bereindicated on this page. For attachment, avoid using glue,staples, or corner mounts. Because it holds the illustrationsecurely to the page without damage, we recommend ScotchRemovable Magic Tape (3M, St Paul, MN). Please do not addletters or numbers to the face of the illustration to identifythe figure (such as lA or IB). This will be done during theprinting process. Arrows should not be placed on radio­graphs prior to photography for print production; they shouldbe placed on the final print and should be removable.

If arrows, letters, and numbers are added to prints, theymust be of professional quality and must be removable.Professional artist service is available to authors withoutcharge. The desired additions may simply be indicated ontissue or a transparent overlay attached to the print.

Illustrations become the property of SCVIR and will bestored for 2 years after publication. Illustrations will bereturned only on receipt of a written request from thecorresponding author.

We suggest that authors make and retain a set of figuresin addition to the four sets submitted to the Journal.
