Method:
A case‐based survey was developed by the authors targeting the four management areas of interest (e.g., the use of the thrombophilia testing, the approach of treatment (anticoagulation vs. observation), duration of treatment, and the use of secondary prophylaxis). The survey was piloted in the primary author’s institution and developed based on respondent feedback. The final survey was posted twice (January 15, 2020, and February 15, 2020) on the Saudi Arabian Pediatric Hematology/Oncology Society (SAPHOS) clinical forum/email database. The survey included three demographic questions: the number of years in practice, patient population, and an annual number of thrombosis patients at the respondent’s center. Case scenarios with asymptomatic CVC‐related thrombosis were utilized. Case management questions included the use of thrombophilia testing, treatment approach, duration of treatment, and secondary prophylaxis with subsequent CVC placement for a 4-year-old male who is admitted for a septic shock from a lung infection. A CVC is placed, and he develops an asymptomatic CVC-related thrombosis in his right subclavian vein found incidentally while performing an ultrasound (US) to evaluate large neck lymph nodes. This is his first thrombotic event, and there is no family history of thrombosis. A week later, a repeat US demonstrates clot resolution. The same CVC remains in place. Six months later, he is admitted to the intensive care unit with a severe trauma injury from motor vehicle accident requiring placement of a new CVC.
