Cerebral abscesses after endovascular coiling of a paraophthalmic aneurysm: Case report and review of the literature.

Conclusion: Infection following coil embolization of cerebral aneurysm is rare. However, it is likely to increase in the setting of increased used of neuroendovascular techniques in the future. Therefore, we suggest that extreme care is taken to ensure proper asepsis during embolization, and a high index of suspicion is maintained in patients with predisposing characteristics (large hemorrhage, ischemia, recurrent endovascular procedures, right-to-left shunt, and concomitant infection). Given the fact that the majority of abscesses occurred in patients who have had ruptured aneurysms, we suggest consideration is given to prophylactic intraprocedural intravenous antibiotics use as seen with open aneurysm treatment.

J Neurol Surg A Cent Eur Neurosurg DOI: 10.1055/s-0039-1685513 Objective Intracranial aneurysms treated with endovascular coil embolization may recur. We investigated the factors affecting aneurysmal recurrence after embolization and effects of endovascular retreatment within 1 year. Methods In 3 years, 1335 patients with 1385 intracranial aneurysms were treated with coil embolization. Factors affecting aneurysm recurrence and the effects of endovascular retreatment were analyzed. Results Angiography immediately following embolization showed total occlusion in 1030 aneurysms (74.4%), neck remnant in...

Conclusions: Use of the FD with adjunctive loose coil embolization might help to alleviate the compressional symptoms caused by intracranial aneurysms. Shrinkage of the aneurysm, a short duration of symptoms, and younger patient age might contribute to favorable outcomes of mass effect-related symptoms.

CONCLUSIONS: PulseRider is being used in both on- and off-label cases following FDA approval. The clinical and radiographic outcomes are comparable in real-world experience to the outcomes observed in earlier studies. Further experience is needed with the device to determine its role in the neurointerventionalist's armamentarium, especially with regard to its off-label use.

The objective of the present work is to study the effect of combining SMPU and radiopaque filler materials on the mechanical, thermal, shape recovery characteristics, and radiopacity. Hybrid composite materials having Barium sulphate (BaSO4) nanoparticles and hydroxyapatite (HaP) nanoparticles in the SMPU matrix are fabricated using a twin-screw extruder, and their properties are compared with that of the composites containing only single filler. The addition of the filler in SMPU is not found to affect its shape-holding characteristics. However, the shape recovery characteristics of the hybrid composites are decreased by ...

ConclusionFor the overall group 15/21 (71.4%) individuals learned the left anterior oblique 30 degrees (LAO30) task within 20  cases, 17/21 (80.9%) learned the aneurysm neck task within 20 cases, 16/21 (76.2%) learned the parent vessel task and 14/21 (66%) learned the neck and parent vessel (anatomical) tasks. Staff were more consistent (i.e. smallest standard deviation) amongst the groups compared to medical students an d residents; however, it was noted that a significant learning effect was observed in participants across every level of medical and angiographic expertise.

CONCLUSIONS: Transferred patients with subarachnoid haemorrhage had lower survival rates. Septic shock and hypernatraemia were important complications among critically ill patients with subarachnoid haemorrhage and were associated increased mortality.

This study aimed to evaluate the image quality and degree of metal artifact reduction using the new-generation gemstone spectral imaging (GSI) and metal artifact reduction software (MARs) and to demonstrate the optimal monochromatic energy level for dual-energy cerebral computed tomography angiography (CTA) in patients with intracranial aneurysm after endovascular treatment. Material and Methods A total of 20 patients with cerebral aneurysms treated with coils or clips underwent CTA using gemstone spectral computed tomography. Artifact index was calculated at each energy level with and without MARs. Signal-to-noise (SNR...

Authors: Yamamoto R, Kaminishi Y, Konishi T, Nakajima T, Abe T, Hiramatsu Y, Mori K Abstract An 83-year-old woman who had undergone total arch replacement for a thoracic aortic aneurysm seven years prior experienced concurrent rupture of second and third branch anastomotic pseudoaneurysms. A stent graft was initially deployed across the pseudoaneurysm from the third branch to the left subclavian artery. Following the left axillary and left carotid arterial bypass, the origin of the second branch was embolized with metallic coils. As a result, both anastomotic pseudoaneurysms were undetectable by both completion ang...
