Object: In single patients with a cerebral aneurysm an external ventricular drain (EVD), an intracranial pressure (ICP) gauge or a combined EVD and ICP gauge placement is necessary after coil embolization and initiation of postprocedural anticoagulation. The aim of this study was to examine the hemorrhage rates of drain placement within 48 h after aneurysm coiling and under anticoagulation or antiplatelet therapy.
Methods: We retrospectively analyzed hemorrhage rates of EVD, ICP gauge or combined EVD and ICP gauge placement in 27 patients within 48 h after coil embolization under different anticoagulation or antiplatelet schemes (heparin, acetylsalicylic acid, clopidogrel). In patients with continuous heparin via perfusor the application was stopped periprocedurally. The results were compared to literature.
Results: Four hemorrhages (14.8%) were observed. Three hemorrhages were petechial and one was by definition a larger hemorrhage with 8 mm×10 mm in diameter.
Conclusions: EVD, ICP gauge or combined EVD and ICP gauge placements within 48 h after cerebral aneurysm coiling and under different anticoagulation or antiplatelet regimens seem to have no increased risk of hemorrhages compared to literature.
