Persistent Thrombocytopenia Indicates Endoleak After Complex Endovascular Aneurysm Repair

F-BEVAR patients who developed high-pressure endoleak had significantly lower platelet counts postoperatively. Aortic imaging should be considered in patients with platelet counts <100,000/μL at POD#4 following F-BEVAR, as 35% of such patients will have a high-pressure endoleak requiring reintervention.Clinical ImpactPersistent thrombocytopenia following F-BEVAR may be an early indication of a high pressure endoleak. Imaging is recommended for patients with platelet count <100,000/μL on POD 4 as 35% of such patients in this study had a high pressure endoleak.
