Thromboembolic complications during aneurysm coiling are rare, with higher rates noted in ruptured aneurysms as patients are not usually premedicated with dual antiplatelet therapy.1,2 Management includes a series of escalating strategies, including medical therapy and intra-arterial thrombolysis.3-6 Additional strategies include mechanical thrombectomy with suction aspiration and stent retrievers.3 Intracranial stenting can be used as a last resource, especially in ruptured cases given the need for dual antiplatelets to prevent stent thrombosis.2 We present the case of a 42-yr-old man with a ruptured left internal carotid artery aneurysm with associated intracranial and intraventricular hemorrhage. The patient was initially presented to an outside facility after he was found in bed unable to speak and with right hemiparesis. The patient consented for surgery and underwent external ventricular drain (EVD) placement for the treatment of obstructive hydrocephalus, followed by diagnostic cerebral angiogram and aneurysm coiling. After the deployment of the last coil, control angiogram showed a small filling defect at the interface between the aneurysm neck and the distal vessel. The patient received intravenous heparin for therapeutic ACT and aspirin load. After progressive enlargement of the thrombus, the patient received intra-arterial glycoprotein (GP) IIB/IIIA inhibitors with a microcatheter positioned proximal to the thrombus. As the thrombus mass continued to enlarge, mechanical thrombectomy with an aspiration catheter was performed twice. Follow-up angiogram 20 min after the second aspiration demonstrated near-complete resolution of the thrombus. The patient recovered from his right hemiparesis, and he was discharged to rehabilitation on POD #21.
