Peripheral vascular ultrasound examinations are important in ultrasound training for medical students

Issues in Teaching Vascular Anatomy: Thoughts and Suggestions from the Clinician's Point of View

The role of anatomy in modern curricula is under reform due to competency of other rapidly evolving subjects and the rapid evolution of several practical aspects and applications dictating modernization of teaching methods as well as of teaching demands. Moreover, modern practice of medicine has put the arterial and vascular system in the center of numerous minimally invasive techniques. Therefore, regardless of their specialty, most doctors should have a very clear and precise knowledge of the vascular anatomy and the basic access techniques from the early years. This viewpoint commentary reflects the experience of the two authors in applying the principles and content of surgical vascular anatomy in undergraduate anatomy teaching and discusses the rationale of this. Moreover, it is suggested that cadaveric dissections should be modified with emphasis on standard surgical vascular exposures and the multidisciplinary teaching of vascular anatomy as a means not only to gain optimal long-term knowledge retention, but also to emphasize through realistic examples on the practical clinical value of vascular anatomy.

Tips and tricks for facilitating teaching of Doppler waveforms and ankle-brachial index in undergraduate level: A practical guide

Although the measurement of ankle-brachial index (ABI) is considered a fundamental skill in assessment and diagnosis of peripheral arterial disease and a predictive tool for cardiovascular events, real-world practice shows that the experience of many health professionals is far from ideal. Not only teaching and practice of ABI measurement in undergraduate medical curricula are limited but various mistakes in the process of calculation, estimation, and interpretation of ABI results in the postgraduate practice have also been documented. Because vascular surgery is a core subject in our medical school, we deal with the difficulties and challenges that undergraduate medical students and nurses face to measure and comprehend ABI. We came up with useful tips and maneuvers to overcome these difficulties. Accordingly, this article provides twelve easy-to-follow useful tips to enhance and facilitate the teaching and comprehension of ABI. Moreover, it favors the simultaneous teaching of Doppler arterial waveform examination as a means to facilitate accurate interpretation and validation of ABI results.

Using Ultrasound to Enhance Medical Students' Femoral Vascular Physical Examination Skills

OBJECTIVES

To determine whether the addition of ultrasound to traditional physical examination instruction improves junior medical students' abilities to locate the femoral pulse.

METHODS

Initially, 150 second-year medical students were taught the femoral pulse examination using traditional bedside teaching on standardized patients and online didactic videos. Students were then randomized into 2 groups: group 1 received ultrasound training first and then completed the standardized examination; and group 2 performed the standardized examination first and then received ultrasound training. On the standardized patients, the femoral artery was marked with invisible ink before the sessions using ultrasound. Compared to these markers, students were then evaluated on the accuracy of femoral artery pulse palpation and the estimated location of the femoral vein. All students completed a self-assessment survey after the ultrasound sessions.

RESULTS

Ultrasound training improved the students' ability to palpate the femoral pulse (P= .02). However, ultrasound did not facilitate correct estimation of the femoral vein's anatomic location (P = .09). Confidence levels in localizing the femoral artery and vein were equal between groups at baseline, and both increased after the ultrasound sessions.

CONCLUSIONS

The addition of ultrasound teaching to traditional physical examination instruction enhanced medical student competency and confidence with the femoral vascular examination. However, understanding of anatomy may require emphasis on precourse didactic material, but further study is required.
