This study aims to develop and implement a pre-operative screening protocol prior to major procedures or surgeries for children with Alagille syndrome, including cardiac catheterization and cardiothoracic surgery (pulmonary artery reconstruction).
Develop and implement an intra-operative protocol for children with Alagille syndrome and acquired von willebrand syndrome.
Compare cardiac intra- and up to 48 hour post-operative bleeding complications, post-operative thrombotic complications within 30 days of surgery, and mortality for (a) children with Alagille syndrome with and without acquired von willebrand syndrome, and (b) children without Alagille syndrome.
This is a single-site study with the goal to enroll 40 patients over the course of the study period. All patients that are referred for Pulmonary Artery Reconstruction will be screened for eligibility. All patients will undergo standard of care pre-operative hematologic screening to evaluate for bleeding disorders (specifically platelet aggregation disorders and acquired von Willebrand Factor deficiency).
The study includes a pre-screening period of up to 4 weeks followed by a 12-months follow-up period as part of the standard of care following pulmonary artery reconstruction surgery for children with Alagille syndrome and a research related protocol for children without Alagille syndrome.
Patients would have blood drawn one time at least 2 weeks in advance of their cardiothoracic surgery. This is the screening protocol to understand if they have a bleeding disorder that would change their management in the operating room and after their surgery. For patients that are found to have a bleeding disorder requiring treatment, they would need post-operatively a blood test daily for up to 7 days total and another blood test weekly for 2 weeks and then once prior to discharge.
