A 72-year-old woman with a history of well-controlled hypertension presents with sudden-onset headache and vomiting. Neurological exam reveals mild neck stiffness but is otherwise normal. A CT angiogram reveals a posterior communicating artery aneurysm, which was subsequently coiled. The image shows a post-coiling angiogram. 24 hours post-procedure, she develops worsening headache and new-onset right-sided weakness. What is the MOST appropriate next step?
A 68-year-old woman with a history of hypertension and hyperlipidemia presents to the emergency department with a sudden onset of left-sided hemianopia and mild right-sided weakness. Her symptoms began approximately 4 hours prior to arrival. Initial neurological examination reveals intact language function and no cognitive deficits. A CT angiogram was performed, followed by endovascular coiling. The provided image shows a post-operative angiogram. Despite the intervention, the patient's hemianopia persists, and her weakness has slightly worsened. What is the MOST appropriate next step in the management of this patient?
A 55-year-old female presents with new onset right homonymous hemianopia 3 months post-aneurysm coiling. Review the image. What is the MOST likely cause?
A 72-year-old male with a history of hypertension presents with a sudden onset of right-sided weakness and expressive aphasia. He underwent endovascular coiling for a PCA aneurysm 1 year ago. The attached image was obtained. What is the MOST likely cause of his current presentation?
A 68-year-old woman with a history of hypertension and hyperlipidemia presented to the emergency department with a sudden onset of left-sided hemianopia and mild right-sided weakness. Her symptoms began approximately 4 hours prior to arrival. Initial neurological examination revealed a left homonymous hemianopia, mild right hemiparesis (4/5 strength), and intact sensation. A CT angiogram was performed, identifying a cerebral aneurysm, and the patient subsequently underwent endovascular coiling. The provided image was obtained immediately following the procedure. Despite the intervention, the patient's left homonymous hemianopia persists, and her right hemiparesis has not improved. Considering the findings on the post-procedure imaging in the context of her ongoing neurological deficits, which of the following is the MOST appropriate immediate management step?

A 72-year-old male with a history of atrial fibrillation and well-controlled hypertension presents with acute onset expressive aphasia and right-sided facial droop. A CT angiogram reveals a posterior cerebral artery aneurysm, which was promptly treated with endovascular coiling. The provided image shows the post-operative angiogram. Despite the intervention, the patient's aphasia persists, and the facial droop has worsened. What is the MOST likely cause of the patient's continued and worsening symptoms?
A 68-year-old woman with a history of hypertension and hyperlipidemia presents to the emergency department with a sudden onset of left-sided hemianopia and mild right-sided weakness. Her symptoms began approximately 4 hours prior to arrival. Initial neurological examination reveals a left homonymous hemianopia, mild right hemiparesis (4/5 strength), and intact sensation. A CT angiogram was performed, and the patient underwent endovascular coiling. The image shows a follow-up angiogram post-procedure. Despite the intervention, the patient's left homonymous hemianopia persists, and her right hemiparesis has not improved. What is the MOST appropriate next step in the management of this patient?
A 72-year-old woman with a history of well-controlled hypertension and type 2 diabetes presents to the emergency department with sudden onset of visual disturbance and mild weakness. She describes the visual issue as a loss of vision in the left half of her visual field, which began approximately 3 hours ago. She also notes some difficulty moving her right arm and leg, which started around the same time. On examination, her vital signs are stable: BP 135/85 mmHg, HR 78 bpm, RR 16/min, Temp 36.8°C, SpO2 98% on room air. Neurological examination confirms a left homonymous hemianopia and mild right hemiparesis (MRC grade 4/5) affecting both upper and lower limbs. Sensation is intact. Reflexes are symmetrical, and plantar responses are flexor. A non-contrast CT head was unremarkable for acute haemorrhage or established infarction. Subsequent CT angiography identified a cerebral aneurysm in a location consistent with her symptoms, and she was taken for endovascular coiling. The procedure was completed approximately 6 hours after symptom onset. The image provided is a digital subtraction angiogram obtained immediately following the coiling procedure. Despite the intervention, her left homonymous hemianopia and right hemiparesis persist without significant improvement. Considering the findings demonstrated in the post-procedure imaging in the context of her ongoing neurological deficits, which of the following is the MOST appropriate immediate management step?
