Cerebral aneurysms are abnormal widening or ballooning of a localized segment of an intracranial blood vessel. Surgical clipping is an important treatment for aneurysms which attempts to exclude blood from flowing into the aneurysmal segment of the vessel while preserving blood flow in a normal fashion. Improper clip placement may ...

Image-guided endovascular intervention (EIGI), using new flow modifying endovascular devices for intracranial aneurysm treatment is an active area of stroke research. The new polyurethane-asymmetric vascular stent (P-AVS), a vascular stent partially covered with a polyurethane-based patch, is used to cover the aneurysm neck, thus occluding flow into the aneurysm. This ...

The standard treatment strategy of intracranial aneurysms includes either endovascular coiling or microsurgical clipping. In certain situations such as in giant or dissecting aneurysms, bypass surgery followed by proximal occlusion or trapping of parent artery is required. The authors assessed the result of extracranial-intracranial (EC-IC) bypass surgery in the treatment ...

First described in 1989, HIV-related aneurysms have been rarely reported. Considered atypical if compared to classic atherosclerotic diseases, they show no preferred location and frequently involve young patients with no other risk factors for atherosclerosis but with an impaired immune system. They are probably related to an auto-immune damage inside ...

The distal segment of the PICA (posterior inferior cerebellar artery) is a very rare localization for the occurrence of intracranial aneurysms. They are almost always presented with SAH (subarachnoid hemorrhage). Hydrocephalus often develops following intraventricular hemorrhage (IVH). The distal PICA segment is a quite difficult localization for neurosurgical procedures. The ...
