Introduction: Point-of-care ultrasound (POCUS) education during medical school develops physicians who are properly prepared for the next generation of medicine. The authors present the case of a first-year medical student who self-diagnosed appendicitis using POCUS.Case Report: A 25-year-old, first-year medical student presented to the emergency d...

To investigate the feasibility of percutaneous arteriovenous fistula creation in consecutive patients screened for first access creation. Prospective study of ultrasound mapping based on the following minimal anatomic requirements: a patent proximal radial artery and adjacent elbow perforating vein with straight trajectory, each greater than or equ...

A substantial proportion of arteriovenous fistulas fail to function adequately for hemodialysis. Existing studies on arteriovenous fistula failure prediction assess patency rather than the more clinically relevant outcome of arteriovenous fistula function. We hypothesized that preoperative demographic and ultrasound characteristics, and postoperati...

Diagnostic cerebral angiograms are increasingly being performed by transradial access (TRA) in adults, following data from the coronary literature supporting fewer access-site complications. Despite this ongoing trend in neuroangiography, there has been no discussion of its use in the pediatric population. Pediatric TRA has scarcely been described ...

To compare the ultrasound characteristics between functional, mature arteriovenous fistulas and functional, non-mature arteriovenous fistulas and to identify the predictors of arteriovenous fistula maturation in the forearm. Patients with newly set-up functional arteriovenous fistulas were enrolled in this prospective cohort study. Ultrasound exami...

Many specialties utilize procedural performance checklists as an aid to teach residents and other learners. Procedural checklists ensure that the critical steps of the desired procedure are performed in a specified manner every time. Valid measures of competency are needed to evaluate learners and ensure a standard quality of care. The objective of...

Midline catheters are widely used in clinical practice. Proper placement of midline catheter tip is usually assessed only by aspirating blood and flushing with normal saline without resistance. To describe the ultrasound-guided tip location for midline catheters and its feasibility and to compare incidence of catheter-related venous thrombosis asso...

We report short-term outcomes of focal high intensity focused ultrasound use for primary treatment of localized prostate cancer. Single-center prospectively collected data on patients with prostate cancer who underwent primary focal high intensity focused ultrasound from January 2016 to July 2018 were included. All patients underwent a 12-core biop...
Objective: To determine if there is an association between uterocervical angle (UCA) and spontaneous preterm birth (sPTB) 95° and >110°. The primary outcome was sPTB 110° was associated with sPTB 110° and sPTB 95° was not associated with sPTB 110° had a sensitivity of 85.7%, specificity of 43.1%, positive predictive value of 53.2%, negative predict...

Ultrasound studies to detect DVT are traditionally performed and interpreted by sonographers and radiologists, respectively, but the growth of point-of-care ultrasound is putting this powerful tool in the hands of front-line physicians. Literature from ambulatory patients in the ED suggests this tool performs well in the hands of nonconventional us...
