Patient selection
The electronic medical record system at our institution was queried for
patients who met inclusion criteria for our study: pediatric patients
(under the age of 21 years) who received interventional thrombolytic
therapy for a symptomatic venous thrombosis of the LE and/or IVC.
Patients that received thrombolysis for additional reasons (line
dysfunction, upper extremity) were excluded in medical record query or
analysis.
