HTTPS:/ /DOI.ORG/10.1177/1591019920947878. THIS RETROSPECTIVE STUDY EVALUATED THE COMPLICATIONS AND OBLITERATION RATES AFTER FLOW DIVERTER PLACEMENT IN PATIENTS TAKING ANTICOAGULANTS. A TOTAL OF 155 CASES WERE TREATED BY PIPELINE FLEX PLACEMENT FOR UNRUPTURED LARGE AND GIANT CEREBRAL ANEURYSMS IN OUR HOSPITAL BETWEEN OCTOBER 2015 AND JUNE 2019. THE GROUPS OF 8 PATIENTS TAKING ANTICOAGULANTS BEFORE OPERATION AND 147 PATIENTS NOT TAKING ANTICOAGULANTS WERE COMPARED. ADDITIONAL COILING WAS PERFORMED IN ONE PATIENT IN THE ANTICOAGULANT GROUP, AND 46 PATIENTS IN THE NONANTICOAGULANT GROUP. DISTAL P ARENCHYMAL HEMORRHAGE WAS OBSERVED IN NO PATIENTS IN THE ANTICOAGULANT GROUP, AND 5 PATIENTS IN THE NON-ANTICOAGULANT GROUP. SYMPTOMATIC ISCHEMIC COMPLICATIONS WERE OBSERVED IN NO PATIENTS IN THE ANTICOAGULANT GROUP, AND 9 PATIENTS IN THE NON-ANTICOAGULANT GROUP. DELAYED ANEURYSM RUPTURE WAS OBSERVED IN 2 PATIENTS IN THE ANTICOAGULANT GROUP, BUT NONE IN THE NONANTICOAGULANT GROUP. ADDITIONAL TREATMENT WAS GIVEN TO 3 PATIENTS IN THE ANTICOAGULANT GROUP, AND 7 PATIENTS IN THE NON-ANTICOAGULANT GROUP. POSTOPERATIVE WORSENING OF NEUROLOGICAL SYMPTOMS WAS OBSERVED IN 2 PATIENTS IN THE ANTICOAGULANT GROUP, AND 6 PATIENTS IN THE NONANTICOAGULANT GROUP. AT THE TIME OF THE FINAL FOLLOW UP, INCOMPLETE OBLITERATION WAS FOUND IN 6 PATIENTS IN THE ANTICOAGULANT GROUP, AND 40 PATIENTS IN THE NON-ANTICOAGULANT GROUP.
