Value of Emergent Neurovascular Imaging for "Seat Belt Injury": A Multi-institutional Study.

BACKGROUND AND PURPOSE: Screening for blunt cerebrovascular injury in patients after motor vehicle collision (MVC) solely based on the presence of cervical seat belt sign has been debated in the literature without consensus. Our aim was to assess the value of emergent neurovascular imaging in patients after an MVC who present with a seat belt sign through a large-scale multi-institutional study. MATERIALS AND METHODS: The electronic medical records of patients admitted to the emergency department with CTA/MRAs performed with an indication of seat belt injury of the neck were retrospectively reviewed at 5 participating institutions. Logistic regression analysis was used to determine the association among age, sex, and additional trauma-related findings with blunt cerebrovascular injury. RESULTS: Five hundred thirty-five adult and 32 pediatric patients from June 2003 until March 2020 were identified. CTA findings were positive in 12/567 (2.1%) patients for the presence of blunt cerebrovascular injury of the vertebral (n = 8) or internal carotid artery (n = 4) in the setting of acute trauma with the seat belt sign. Nine of 12 patients had symptoms, signs, or risk factors for cervical blunt cerebrovascular injury other than the seat belt sign. The remaining 3 patients (3/567, 0.5%) had Biffl grades I-II vascular injury with no neurologic sequelae. The presence of at least 1 additional traumatic finding or the development of a new neurologic deficit was significantly associated with the presence of blunt cerebrovascular injury among adult patients, with a risk ratio of 11.7 (P = .001). No children had blunt cerebrovascular injury. CONCLUSIONS: The risk of vascular injury in the presence of the cervical seat belt sign is small, and most patients diagnosed with blunt cerebrovascular injury have other associated findings. Therefore, CTA based solely on this sign has limited value (3/567 = a 0.5% positivity rate). We suggest that in the absence of other clinical findings, the seat belt sign does not independently justify neck CTA in patients after trauma.

Parental Leave and Neuroradiology Fellowships.

BACKGROUND AND PURPOSE: A uniform policy on parental leave in radiology training programs is lacking. Although previous publications have addressed the status of parental leave policy among radiology residency programs, the state of parental leave in radiology fellowships has not been addressed to date. Our aim was to determine the state of parental leave policies in American neuroradiology fellowship programs. MATERIALS AND METHODS: An Internet survey was sent to the directors of neuroradiology fellowship programs listed on the Accreditation Council for Graduate Medical Education Web site (n = 87) in January 2020. The questionnaire assessed the policies of the fellowship programs and Program Directors' attitudes toward maternal and paternal leave. Four reminders were sent during the 3 weeks before closing data collection. RESULTS: The response rate was 76% (66/87). Ninety-four percent (62/66) of program directors claimed to have a maternal leave policy, of which 51/62 (82%) were written and 53/62 (85%) were paid. Additionally, 77% (51/66) had a policy for paternal leave, of which 80% (41/51) were written and 76% (39/51) were paid. The average length of paid leave was 6.7 ± 3.25 weeks for new mothers and 2.9 ± 2 weeks for new fathers. Unpaid leave was mostly based on the Family and Medical Leave Act. Fellows were responsible for making up call duties during the parental leave in 47% of the programs. Radiation exposure was restricted in 89% of the programs during pregnancy. Policies addressed breast feeding and untraditional parenthood in just 41% of the responding programs. Most program directors supported the development of a unified national policy on maternal (83%) and paternal (79%) leave. CONCLUSIONS: Most neuroradiology fellowship programs have explicit maternal and paternal leave policies that grant paid leave to trainees. Some also offer unpaid leave, mostly through Family and Medical Leave Act guidelines. A uniform policy derived from the Accreditation Council for Graduate Medical Education and/or American Board of Radiology would be useful and overwhelmingly accepted.
