This dataset supports the findings of the vascular e-Learning during the COVID-19 pandemic survey (the EL-COVID survey). The General Data Protection Regulation (GDPR) of the European Union was taken into consideration in all steps of data handling. The survey was approved by the institutional ethics committee of the Primary Investigator and an online English survey consisting of 18 questions was developed ad-hoc.

- The COVID-19 pandemic has significantly impacted how vascular surgeons and trainees share knowledge, leading to a survey aimed at assessing their e-learning needs and the effectiveness of online education in this field.
- The survey, conducted between June and October 2020, gathered responses from 856 participants across 84 countries, revealing that over half had participated in multiple online activities, with many rating these sessions positively.
- Key factors influencing participation included the topic and the reputation of presenters, while challenges like limited time, lack of protected learning time, and absence of accreditation were noted as significant obstacles to effective e-learning.
Background: As many as 10% of airline passengers travelling without prophylaxis for long distances may develop a venous thrombosis. There is, however, no evidence that economy class travellers are at increased risk of thrombosis.
Objectives: A suitably powered prospective study, based on the incidence of deep-vein thrombosis (DVT) reported in previous studies on long-haul flights, was designed to determine the incidence of positive venous duplex scans and D-dimer elevations in low and intermediate-risk passengers, comparing passengers travelling in business and economy class.
