There is little data on management and outcomes of atrial fibrillation (AF) patients on direct oral anticoagulants (DOAC) undergoing general surgery.We retrospectively assessed 98 surgeries in 85 nonvalvular AF patients aged 73 ± 8 (59 men) receiving DOACs. Cardiac, emergency, and minimally invasive surgeries were excluded.The CHA

Antiplatelet agents are typically administered before and after treatment using flow-diverter stents (FDS) to prevent thrombotic complications, but the effects of anticoagulants are unclear. We present a patient with a giant aneurysm treated with an FDS. The thrombus within the aneurysm was dissolved when a direct factor Xa inhibitor was administered to treat lower limb venous thrombosis that occurred secondary to steroid use.. A 60-year-old woman with a 30-mm giant thrombosed aneurysm in the cavernous segment of the right internal carotid artery presenting with headache and right abducens nerve palsy was treated by placing an FDS. Diplopia and increased pain in her right eye appeared on postoperative day 7, and both were alleviated by continuous oral administration of prednisolone. Angiography 3 months postoperatively revealed that the aneurysm thrombosis had progressed, and there were signs of healing. However, at the same time, lower limb venous thrombosis occurred, which was treated by continuous edoxaban. Six months after surgery, her headaches worsened and angiography showed that the aneurysm was again contrast enhanced and that the thrombus within the aneurysm had dissolved. After discontinuing edoxaban 9 months after surgery, the aneurysmal thrombosis had again rapidly progressed.. Administration of a direct factor Xa inhibitor during healing after placing an FDS may cause dissolution of an existing thrombus; therefore factor Xa inhibitors must be used with caution.

Cranial artery dolichoectasia is characterized by dilated, elongated, and tortuous cranial arteries. Dolichoectasia and dolichoectatic aneurysm-particularly of the internal carotid arteries (ICAs)-are rare but can lead to stroke. We report a case of suspected recurrent acute cerebral infarction and dolichoectatic aneurysm of the left ICA combined with right dolichoectatic aneurysm, vertebrobasilar dolichoectasia, and atrial fibrillation.. An 80-year-old man experienced 3 days of recurrent aphasia episodes. He had a history of atrial fibrillation and hypertension. Neurologic findings indicated Wernicke aphasia. Magnetic resonance imaging showed acute cerebral infarction in the left temporal and parietal lobes. Magnetic resonance angiography and cerebral angiography showed dolichoectatic aneurysms in the C1-2 portion of the bilateral ICAs and vertebrobasilar dolichoectasia. Possible diagnoses included convulsion, cardioembolic infarction, atherothrombotic cerebral infarction, and acute ischemic stroke associated with the dolichoectatic aneurysm of the left ICA. Oral antiplatelet drugs, direct oral anticoagulants, and anticonvulsants were administered. Nine months after initial hospitalization, the patient had a recurrence of acute ischemic stroke and was rehospitalized. He was treated with a new direct oral anticoagulant, clopidogrel, statins, and ethyl icosapentate. At 2 years after initial hospitalization, he has had no recurrence of stroke, has a modified Rankin Scale score of 2, and is currently being followed as an outpatient.. A direct oral anticoagulant (edoxaban) and clopidogrel were effective for suspected recurrent acute ischemic stroke associated with dolichoectatic aneurysm of the ICA combined with contralateral dolichoectatic aneurysm, vertebrobasilar dolichoectasia, and atrial fibrillation.
