The American Institute of Ultrasound in Medicine (AIUM) is a multidisciplinaryassociation dedicated to advancing the safe and effective use of ultrasound inmedicine through professional and public education, research, development ofguidelines, and accreditation. To promote this mission, the AIUM is pleased topublish in conjunction with the American College of Radiology (ACR) and theSociety of Radiologists in Ultrasound (SRU) this AIUM Practice Guideline forthe Performance of Diagnostic and Screening Ultrasound Examinations ofthe Abdominal Aorta in Adults.The AIUM represents the entire range of clinical and basic science interests inmedical diagnostic ultrasound, and, with hundreds of volunteers, this multidisciplinaryorganization has promoted the safe and effective use of ultrasound inclinical medicine for more than 50 years. This document and others like it willcontinue to advance this mission.Practice guidelines of the AIUM are intended to provide the medical ultrasoundcommunity with guidelines for the performance and recording ofhigh-quality ultrasound examinations. The guidelines reflect what the AIUMconsiders the minimum criteria for a complete examination in each area butare not intended to establish a legal standard of care. AIUM-accredited practicesare expected to generally follow the guidelines with recognition thatdeviations from these guidelines will be needed in some cases, dependingon patient needs and available equipment. Practices are encouraged to gobeyond the guidelines to provide additional service and information as needed.14750 Sweitzer Ln, Suite 100Laurel, MD 20707-5906 USA800-638-5352 • 301-498-4100www.aium.orgOriginal copyright 2006; revised 2010—AIUM PRACTICE GUIDELINES—Abdominal Aorta in Adults
I. IntroductionThe clinical aspects contained in specific sections of thisguideline (Introduction, Indications/Contraindications,Specifications of the Examination, and EquipmentSpecifications) were developed collaboratively by theAmerican Institute of Ultrasound in Medicine (AIUM),the American College of Radiology (ACR), and the Societyof Radiologists in Ultrasound (SRU). Recommendationsfor physician requirements, written request for the examination,procedure documentation, and quality controlvary among the three organizations and are addressedby each separately.These guidelines are intended to assist in the performanceand interpretation of a dedicated sonographic examinationof the abdominal aorta. The examination may be performedas a diagnostic or screening study. Comprehensivepopulation screening programs have not yet been developedin the United States but do exist elsewhere in theworld. 1,2 While it is not possible to detect every abnormality,following this guideline will maximize the detection ofabnormalities of the abdominal aorta.II. Qualifications and Responsibilities ofPersonnelSee www.aium.org for AIUM Official Statements includingStandards and Guidelines for the Accreditation ofUltrasound Practices and relevant Physician TrainingGuidelines.III. Indications/ContraindicationsIndications for ultrasound of the abdominal aorta includebut are not limited to:A. Diagnostic Evaluation for an Abdominal AorticAneurysm1. Palpable or pulsatile abdominal mass.2. Unexplained lower back pain, flank pain, orabdominal pain.3. Follow-up of a previously demonstrated abdominalaortic aneurysm.4. Follow-up of patients with an abdominal aorticand/or iliac endoluminal stent graft.B. Screening Evaluation for an Abdominal AorticAneurysm1. Men 65 years or older.2. Women 65 years or older with cardiovascular riskfactors.3. Patients 50 years or older with a family historyof aortic and/or peripheral vascular aneurysmaldisease.4. Patients with a personal history of peripheralvascular aneurysmal disease.Groups with additional risk include patients with a historyof smoking, hypertension, and certain connective tissuediseases (eg, Marfan syndrome).There are no absolute contraindications to ultrasoundof the aorta. If aortic rupture or dissection is clinicallysuspected, ultrasound is usually not the examinationof choice.IV. Written Request for the ExaminationThe written or electronic request for an ultrasound examinationshould provide sufficient information to allow forthe appropriate performance and interpretation of theexamination.The request for the examination must be originated by aphysician or other appropriately licensed health careprovider or under their direction. The accompanying clinicalinformation should be provided by a physician orother appropriate health care provider familiar with thepatient’s clinical situation and should be consistent withrelevant legal and local health care facility requirements.V. Specifications of the ExaminationA. Diagnostic ExaminationThe examination includes the following, when feasible:1. Abdominal aorta:a. Longitudinal images (along the long axis ofthe vessel):i. Proximal;ii. Mid;iii. Distal.Effective March 27, 2010—AIUM PRACTICE GUIDELINES—Abdominal Aorta in Adults 1
