Zusammenfassung:Background Dual antiplatelet therapy is associated with increased rates of intracerebral hemorrhage, especially in the context of subarachnoid hemorrhage. We present a case of a spontaneous hemorrhage in a patient treated with a Pipeline stent for a ruptured dissecting vertebrobasilar aneurysm and the novel use of direct application of platelets during surgery to control bleeding. Case Description A 54-year-old previously healthy woman presented with an intradural right vertebral artery dissection with a ruptured 6-mm pseudoaneurysm. The patient was started on aspirin and clopidogrel and the vessel was reconstructed with 2 Pipeline Embolization Devices. On postbleed day number 14, she became obtunded with a blown right pupil; computed tomography of the head demonstrated a large right temporal intracerebral hematoma. The patient was taken emergently to the operating room for evacuation of the clot. Intraoperatively, satisfactory control of bleeding was not achieved despite transfusing several units of platelets intravenously. Ultimately, a mixture of Floseal and platelets applied directly to the hematoma wall allowed prompt hemostasis. At 3 months the patient was doing extremely well clinically and angiography demonstrated occlusion of the aneurysm. Conclusions This is the first reported description of direct application of platelets to achieve intraoperative hemostasis. Platelets are activated by thrombin and collagen and the use of Floseal (a bovine-derived, gelatin matrix and human-derived thrombin) further potentiated the effectiveness of this strategy. With the increased incidence of intracerebral hemorrhage associated with dual antiplatelet therapy, this technique may provide a useful tool in the neurosurgical armamentarium.
