Currently, endovascular coiling is a popular treatment for basilar tip aneurysms, which usually involve a wide neck. Serious complications can occur when the posterior cerebral artery (PCA) originating from a wide neck is not properly preserved. Accordingly, various adjunctive procedures using stents or a balloon have been introduced. Herein we report two cases of basilar tip aneurysms in which...

Use of stent assisted coiling of intracranial aneurysms has shown a recent increase. Despite technical improvement and accumulated clinical experiences, due to insufficient study data, debate over short and long term durability and associated complication has continued.To the best of our knowledge, this case report, for the first time, demonstrates delayed self-expansion phenomenon occurring as...

SUMMARY A 69-year-old woman had a symptomatic cervical carotid stenosis coupled with a coincidental unruptured cerebral aneurysm in the carotid distal segment. She underwent endovascular coiling for the aneurysm and then carotid stent placement (CAS) 1 month later. Both lesions were treated successfully and neither complications nor strokes occurred after the procedures. Staged endovascular tre...

A new model is proposed to explain coiling of myelins composed of fluid bilayers. This model allows the constituent bilayer cylinders of a myelin to be non-coaxial and the bilayer lateral tension to vary from bilayer to bilayer. The calculations show that a myelin would bend or coil to lower its free energy when the bilayer lateral tension is sufficiently large. From a mechanical point of view,...

The control for the processing of precursor liquids determines whether the properties and functions of the final material product can be engineered. An inherent challenge of processing viscous liquids arises from their large resistance to deform. Here, we report on the discovery of an electric approach that can significantly contribute to address this challenge. The applied electric force can i...

Positive movement to some ionic solutes and biological compounds was exhibited by male soybean cyst nematodes, Heterodera glycines. Males were highly attracted to different concentrations of glycerol, moderately attracted to KOH, and repelled by HC1. Males were highly attracted to some amino acids, adenosine 3':5'-cyclic monophosphate, and adenosine 5'-monophosphate. The amino acids that were m...

22 Multidisciplinary treatment of cerebral aneurysms includes endovascular coiling and open 23 neurosurgical clipping techniques, however our understanding of long-term outcomes after 24 coiling of large cerebral aneurysms remains limited. We present a case involving the 25 development of a previously coiled posterior inferior cerebellar artery (PICA) aneurysm in a 6426 year-old man with lesion...

The purpose is to describe a case of traumatic right extracranial internal carotid artery (EICA) pseudoaneurysm, which is a rare entity and the evolution of treatment from surgery to minimally invasive intervention by endovascular stenting and coiling. We reported a case of traumatic right EICA pseudoaneurysm who presented with multiple cranial nerve palsies. Multiple radiological examinations ...

Kinking and coiling of the internal carotid artery (ICA) sometimes may result in symptomatic cerebrovascular disease, but indisputable evidence linking the two conditions is lacking. However, there is enough evidence to warrant careful consideration of surgical correction in patients who have features of the carotid artery syndrome and kinking of the ICA as shown on angiography. Kinking or buck...
