Perceptions of Exposure to Neuroendovascular Intervention During Neurology Training in LATAM: An International Multicenter Exploratory Survey and Review of the Literature

Abstract

Aim

The aim is to assess the exposure to neuroendovascular intervention and perceptions among trainees in Latin America.

Methods

A descriptive and cross-sectional study was conducted from October to December 2024 and was aimed at neurology residents and/or fellows in Latin American hospitals. An electronic questionnaire was conducted on the Google Forms platform. Prior to applying the instrument, it was subjected to content and appearance validation. The survey was sent up to three times by email to avoid a low response rate. The information was then transferred to a database without identifiers, ensuring the anonymity and confidentiality of the information.

Results

A total of 83 surveys were collected from respondents across 16 Latin American countries. The majority were senior neurology residents (75.9%). Around one-third (34.9%) expressed interest in pursuing future training in neuroendovascular intervention. Among those considering further training, only 19.7% would do so in their current institution, while 55.7% would prefer another Latin American country. Regarding leadership of the endovascular unit, 38.8% were led by neurologists, 31.3% by neurosurgeons, and 26.9% by radiologists. In 75% of units, at least one interventional neurologist was present. Over 80% believed that a formal rotation in neuroendovascular intervention would improve their overall training. However, only 17.8% anticipated they would encounter no major obstacles in pursuing a career in neurointervention. Among the most perceived barriers were a lack of logistical resources such as devices and consumables (37.3%), resistance from other specialties like neurosurgery and radiology (31.0%), and underprepared healthcare systems that hinder the development of neurointerventional services (28.9%).

Conclusion

Most trainees consider that neuroendovascular exposure needs to be part of the curriculum of contemporary neurology residency programs in Latin America. More exposure will probably positively impact their perception of training and increase their interest in pursuing a subspecialization in the field.
