The patient remained intubated and was transferred towards the intensive care unit. On PPD 2, he became hemodynamically unstable and was found to have a big rectus sheath and right groin hematoma (figure 2E). He was taken towards the operating room with vascular surgery for placement of a covered iliofemoral stent for hemorrhage manage. On PPD three, he was restarted on full dose aspirin and prasugrel. Precisely the same day, the patient was noted to become much less responsive, tachypneic and tachycardic. Chest CT demonstrated huge bilateral pulmonary emboli. He was started on a bivalirudin intravenous drip. He was extubated on PPD 5. Coumadin therapy was began for deep venous thromboses and pulmonary emboli. He was discharged to a rehabilitation facility on PPD 15 and had a meaningful neurological recovery.Case NoA woman in her sixth decade of life with a 10 year history of an asymptomatic left superior cerebellar artery aneurysm presented having a 2 month history of diplopia. Catheter angiography revealed a 12322 mm left superior cerebellar artery aneurysm (figure 4A). The patient was loaded with clopidogrel (300 mg orally) then started on complete dose aspirin and clopidogr.
