AbstractBACKGROUND AND IMPORTANCEEmbolization of shotgun pellet from the peripheral vasculature to the cerebral vessels has been a known phenomenon that has been reported previously in the literature. However, there is no consensus on clinical indications for intervention, best modality of intervention or management upon leaving the hospital. We describe a case of a shotgun pellet in the neck that embolized to the middle cerebral artery that was treated with open surgery. Discussed is the initial management on presentation, timing of intervention from surgery and detailed surgical technique.CLINICAL PRESENTATIONA 20-yr-old man presented after being shot at close range with a shotgun. He was neurologically intact on exam. Initial screening computed tomography (CT) of the brain noted a shotgun pellet in the region of the sylvian fissure without intracranial hemorrhage. Computed tomography angiography again displayed pellet in the vicinity of the left middle cerebral artery. He was emergently taken for an awake cerebral angiogram and subsequent surgical extraction of the shotgun pellet.CONCLUSIONMissile embolization of a bullet fragment to the intracranial vasculature is rare and requires difficult decisions regarding management. Critical factors that are to be considered prior to treatment include neurological clinical presentation, timing of the trauma, and anatomic location of injury. Patients who are without neurological deficit that display compromised blood flow require immediate cerebral angiogram followed by surgical intervention depending on location.

Abstract Sidewall aneurysm treatment often requires complex management strategies. These can include advanced clipping techniques or stent-assisted coiling techniques. Endovascular coiling alone has been associated with high recurrence rates and is often not feasible.1-4 Flow-diversion embolization has recently become a standard of care for many aneurysms, demonstrating high occlusion rates.4,5 However, the third generation of coil-assist stents can be delivered with 0.0165” microcatheters, being an ideal adjunct to manage this group of aneurysms in more distal locations. In this video, a 16-yr-old teenager with Parry-Romberg syndrome and congenital adrenal hyperplasia had an incidental finding of a 6.5-mm sidewall aneurysm arising off the angular branch of the left middle cerebral artery, found during the work-up of complex partial seizures. The patient consented to the procedure. Due to his young age and aneurysm size, a decision was made to treat the aneurysm through an endovascular approach. Under general anesthesia, a transfemoral approach was carried out using a 6-French short sheath. A 6-French guiding catheter was left in the distal cervical left internal carotid artery; a 0.0165” microcatheter was used to first deploy a 3.0 × 15 mm Neuroform Atlas stent, completely covering the length of the aneurysm. Then, the stent was traversed with the microcatheter to coil the aneurysm. Follow-up cerebral angiogram confirmed complete occlusion of the aneurysm.

This report describes a 42-year-old male with a 5-year history of transient ischemic attacks (TIAs), migraines, previous strokes, and symptoms referable to a left middle cerebral artery (MCA) territory event. Computed tomography angiography (CTA) and magnetic resonance angiography (MRA) revealed severe stenoses in the proximal left MCA and proximal left anterior cerebral artery (ACA). Transcranial Doppler ultrasound/Transcranial Doppler imaging (TCD/TCI) and cerebral angiogram confirmed the stenoses with a mean flow velocity (MFV) at the proximal left MCA, with a velocity of 230 cm/s. A Wingspan Stent System stent was placed in the proximal left MCA. Cerebral angiogram and serial TCD examinations performed post stent placement showed a patent left MCA without stenosis and a MFV of 55 cm/s. The left ACA was occluded following proximal left MCA stent placement. This case highlights the usefulness of TCD in the assessment of the MCA and other basal cerebral arteries.

A duplicated middle cerebral artery (DMCA) is a common anomaly. However, aneurysms arising from the origin of a DMCA are extremely rare. A 22-year-old female was admitted to our hospital with a World Federation of Neurosurgical Societies grade 2 subarachnoid haemorrhage. Four-vessel angiography revealed a DMCA and an aneurysm arising from the origin of this artery. The aneurysm was successfully treated by embolization, and the patient was discharged 2 weeks later. Ruptured aneurysms arising from the origin of a DMCA can be successfully treated by embolization. These aneurysms are small and 3D-computed tomography reconstruction is mandatory to detect them. It is important to preserve the DMCA during the treatment procedure.

Background Post-stroke cognitive impairment can occur after damage to various brain regions, and cognitive deficits depend on infarct location. The Mini-Mental State Examination (MMSE) is still widely used to assess post-stroke cognition, but it has been criticized for capturing only certain cognitive deficits. Along these lines, it might be hypothesized that cognitive deficits as measured with the MMSE primarily involve certain infarct locations. Aims This comprehensive lesion-symptom mapping study aimed to determine which acute infarct locations are associated with post-stroke cognitive impairment on the MMSE. Methods We examined associations between impairment on the MMSE (<5th percentile; normative data) and infarct location in 1198 patients (age 67 ± 12 years, 43% female) with acute ischemic stroke using voxel-based lesion-symptom mapping. As a frame of reference, infarct patterns associated with impairments in individual cognitive domains were determined, based on a more detailed neuropsychological assessment. Results Impairment on the MMSE was present in 420 patients (35%). Large voxel clusters in the left middle cerebral artery territory and thalamus were significantly (p < 0.01) associated with cognitive impairment on the MMSE, with highest odds ratios (>15) in the thalamus and superior temporal gyrus. In comparison, domain-specific impairments were related to various infarct patterns across both hemispheres including the left medial temporal lobe (verbal memory) and right parietal lobe (visuospatial functioning). Conclusions Our findings indicate that post-stroke cognitive impairment on the MMSE primarily relates to infarct locations in the left middle cerebral artery territory. The MMSE is apparently less sensitive to cognitive deficits that specifically relate to other locations.

AbstractPurpose: Computed tomography perfusion (CTP) has been performed to predict which patients with aneurysmal subarachnoid hemorrhage are at risk of developing delayed cerebral ischemia (DCI). Patients with severe arterial narrowing may have significant reduction in perfusion. However, many patients have less severe arterial narrowing. There is a paucity of literature evaluating perfusion changes which occur with mild to moderate narrowing. The purpose of our study was to investigate serial whole-brain CTP/computed tomography angiography in aneurysm-related subarachnoid hemorrhage (aSAH) patients with mild to moderate angiographic narrowing. Methods: We retrospectively studied 18 aSAH patients who had baseline and follow-up whole-brain CTP/computed tomography angiography. Thirty-one regions of interest/hemisphere at six levels were grouped by vascular territory. Arterial diameters were measured at the circle of Willis. The correlation between arterial diameter and change in CTP values, change in CTP in with and without DCI, and response to intra-arterial vasodilator therapy in DCI patients was evaluated. Results: There was correlation among the overall average cerebral blood flow (CBF; R=0.49, p<0.04), mean transit time (R=–0.48, p=0.04), and angiographic narrowing. In individual arterial territories, there was correlation between changes in CBF and arterial diameter in the middle cerebral artery (R=0.53, p=0.03), posterior cerebral artery (R=0.5, p=0.03), and anterior cerebral artery (R=0.54, p=0.02) territories. Prolonged mean transit time was correlated with arterial diameter narrowing in the middle cerebral artery territory (R=0.52, p=0.03). Patients with DCI tended to have serial worsening of CBF compared with those without DCI (p=0.055). Conclusions: Our preliminary study demonstrates there is a correlation between mild to moderate angiographic narrowing and serial changes in perfusion in patients with aSAH. Patients developing DCI tended to have progressively worsening CBF compared with those not developing DCI.

✓ An 11-month-old boy was admitted for evaluation of drowsiness, vomiting, and convulsions. Computerized tomography showed subarachnoid blood in the left sylvian fissure and a small intracerebral hematoma in the temporal lobe. Angiography revealed several aneurysms of the left middle cerebral artery (MCA). During surgery, 13 aneurysms were found arising from one main branch of the left MCA, and this segment of the MCA was trapped. Somatosensory evoked potentials did not show any change during surgery. The diseased arterial segment was examined histologically and the pathogenetic aspects of the case are discussed. Control angiography 6 months later excluded systemic disease or other aneurysms. The rarity of such lesions in childhood and their successful surgical treatment are discussed briefly.
