Mechanical thrombectomy with the novel InThrill thrombectomy catheter for portal vein thrombosis and occluded transjugular intrahepatic portosystemic shunt: A case series

Abstract

Portal vein thrombosis (PVT) is commonly treated with anticoagulation alone, though rates of recanalization with anticoagulation vary widely. Four patients with PVT (n = 3) or occluded transjugular intrahepatic portosystemic shunt (n = 1) were treated using the InThrill thrombectomy catheter. Mechanical thrombectomy was technically successful in all patients, resulting in >90% thrombus removal from each patient. Three patients were discharged home, and patency and symptom resolution were maintained at a 2-month follow-up. One patient was discharged to rehabilitation due to comorbidities and expired after presenting with a myocardial infarction and pneumonia 2 weeks post-procedure.
