Abstract

A female patient in her early 60's with advanced liver cirrhosis and thrombocytopenia having a platelet count under 30,000/µL, visited an outpatient clinic. Computed tomography angiography revealed an unruptured aneurysm on the left middle cerebral artery bifurcation with 6.0 mm of maximal diameter. Endovascular coiling was planned, considering the patient's medical condition. Eight pints of platelet concentrate were transfused 6 hours before the procedure, and a platelet count of 57,000/ µL was achieved 3 hours before the procedure. No antiplatelet premedication and intraprocedural heparin was administered. A bail-out use of intra- or postoperative Tirofiban (Aggrastat®) was prepared for inadvertent thromboembolic events. The aneurysm was successfully occluded with no procedure-related event. The patient’s hospital course was uneventful, and she was discharged without complications. Despite the potential hemorrhagic risk caused by hemostatic failure in patients with cirrhosis, successful endovascular coiling can be performed with highly individualized management.
