Background Rupture of infectious intracranial aneurysms (IIAs) is associated with a high likelihood of mortality. Endovascular treatment of IIAs via parent artery sacrifice offers good efficacy and outcomes; however, depending on the lesion’s location, neurologic deficit may result. Case description We describe a pediatric patient with ruptured IIAs off the left middle cerebral artery (MCA) treated with coil embolization and endovascular flow diversion using the Pipeline Flex Embolization Device (PED) with Shield technology. We chose to place a flow diverter because 1) there was a second, more distal IIA not amenable to direct coil embolization, 2) there was significant potential for aneurysm regrowth and need for retreatment, and 3) we believed the diseased parent MCA needed to be reconstructed. Conclusions In the setting of previous hemicraniectomy, PED-Shield gave us the option to discontinue dual antiplatelet therapy should the patient require further neurosurgical intervention. Our case supports a role for PED-Shield to address ruptured pseudoaneurysms.

Control Angiography

✓ 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.

Aneurysm Occlusion

Intracranial aneurysms in the pediatric population are rare entities. The authors recently treated a 9-month-old infant with a 19-mm recurrent, previously ruptured, and coil-embolized left middle cerebral artery (MCA) pseudoaneurysm, which was treated definitively with single-stage Pipeline-assisted coil embolization. The patient was 5 months old when she underwent resection of a left temporal Grade 1 desmoplastic infantile ganglioglioma at an outside institution, which was complicated by left MCA injury with a resultant 9-mm left M1 pseudoaneurysm. Within a month, the patient had two aneurysmal rupture events and underwent emergency craniectomy for decompression and evacuation of subdural hematoma. The pseudoaneurysm initially underwent coil embolization; however, follow-up MR angiography (MRA) revealed aneurysm recanalization with saccular enlargement to 19 mm. The patient underwent successful flow diversion–assisted coil embolization at 9 months of age. At 7 months after the procedure, follow-up MRA showed complete aneurysm occlusion without evidence of in-stent thrombosis or stenosis. Experience with flow diverters in the pediatric population is still in its early phases, with the youngest reported patient being 22 months old. In this paper the authors report the first case of such a technique in an infant, whom they believe to be the youngest patient to undergo cerebral flow diversion treatment.

Middle cerebral artery aneurysms, especially those with complex morphology, are considered excellent aneurysms for surgical clipping, given the challenges that exist with current endovascular techniques. We present a case of a large, complex, left middle cerebral artery aneurysm treated with microsurgical clipping. This video highlights critical steps in obtaining proximal and distal control as well as subarachnoid dissection necessary to prepare the aneurysm for final clipping.The video can be found here: http://youtu.be/RlKH2Km9z5Y.

Abstract BACKGROUND AND IMPORTANCE Fusiform intracranial aneurysms remain challenging lesions to treat. These aneurysms have historically required bypass procedures or clip remodeling constructs for cure. Recently, endovascular specialists have reported experience with flow diversion for complex fusiform aneurysms of the vertebrobasilar system, with mixed results. Vascular anatomy for anterior circulation fusiform aneurysms may make these lesions more amenable to flow diversion and embolization procedures; however, published experience with these techniques is lacking. In this report, we describe a sequential coiling-assisted deployment of flow diverter for the treatment of fusiform middle cerebral artery (MCA-M1) aneurysms in 2 cases, 1 presenting acutely with subarachnoid hemorrhage and another with progressive aneurysm enlargement. CLINICAL PRESENTATION Two patients, a 36-yr-old male presenting with subarachnoid hemorrhage and a 60-yr-old female presenting with aneurysm enlargement were treated for fusiform aneurysms of the M1 segment of the MCA using a sequential, partial deployment of coils and flow diverter through 2 microcatheters to facilitate mutual mechanical support for both coil and flow diverter (Pipeline Embolization Device; Medtronic Inc, Dublin, Ireland). Both patients achieved favorable outcomes and follow-up angiography demonstrated complete vessel reconstruction in both cases. CONCLUSION The treatment of complex, fusiform, large vessel aneurysms remains challenging. As experience with new endovascular technologies and techniques grows, these lesions may be treated safely with interventional methods. The technique of partial flow diverter deployment and stabilization with coils with sequential delivery of both devices using dual microcatheter was both safe and effective.

Distal Middle Cerebral Artery

Intracranial aneurysms of the distal intracranial arteries are uncommon lesions which are difficult to treat with surgical techniques. Distal middle cerebral artery (MCA) aneurysms constitute approximately 5% of all MCA aneurysms. We report the results of our coil embolization for the treatment of distal MCA aneurysms. Eleven patients (four men and seven women, average age 37 years) with distally located MCA aneurysms were treated. Four of the aneurysms were fusiform in shape and the remainder were saccular. Seven of the aneurysms were in the dominant hemisphere. Four of the seven patients who had saccular aneurysms were treated with selective aneurysm embolization. The remaining seven patients were treated with aneurysmal sac and parent artery coiling. All patients had good retrograde flow into the peripheral branches of the occluded artery. All the procedures were completed successfully without any additional neurological deficits. Coil embolization is a safe and effective technique for the treatment of distal MCA aneurysms. If the parent artery cannot be preserved, pial collaterals can supply adequate blood to prevent neurological deficits.

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.

We report the successful treatment of multiple ruptured fusiform middle cerebral artery (MCA) aneurysms in a 10-month-old girl. This previously healthy infant presented with subarachnoid haemorrhage and was found to have multiple irregular dilatations of the superior division branch of the right MCA. Cerebral angiography was performed and confirmed the presence of multiple fusiform aneurysms of the MCA. After multidisciplinary team discussion, it was decided to treat the aneurysms with endovascular approach, using a flow-diverter. Microsurgical clipping was deemed risky because of the high likelihood of parent artery occlusion and expectant management was also considered inappropriate because of the risk of re-bleeding. Dual antiplatelet therapy was started, and a flow-diverter was successfully delivered in the superior division branch of the right MCA. The post-operative course was uneventful, MRI at 12 months did not show any sign of recurrence and at 3 years of age the patient had a normal neurological examination.
