Neurogenic pulmonary edema (NPE) is a well-known entity, occurs after acute severe insult to the central nervous system. It has been described in relation to different clinical scenario. However, NPE has rarely been mentioned after endovascular coiling of intracranial aneurysms. Here, we report the
OBJECTIVE
Perianeurysmal edema is rare and is associated with expansion of intracranial aneurysms despite adequate endovascular treatment. The natural history of this condition is poorly understood. We present a case series of perianeurysmal edema to investigate the incidence, natural history and
There is considerable interest in the development of symptomatic inflammatory reactions following coil embolization of cerebral aneurysms. Patients have experienced a range of adverse events, usually after treatment of moderately large aneurysms with modified "bioactive" coils. More recently, it has
OBJECTIVE
The underlying mechanisms causing intracranial perianeurysmal edema (PAE) are still poorly understood. Since PAE is most frequently observed in giant intracranial aneurysms (GIAs), the authors designed a study to examine the occurrence of PAE in relation to the location, size, and partial
A case of ruptured distal anterior cerebral artery aneurysm associated with neurogenic pulmonary edema is presented. It is suggested that this association should not be accepted as a "taboo" for radical intervention followed by a proper management of ventilation with positive end-expiratory pressure
Aneurysmal volume expansion after endovascular treatment is caused by intra-aneurysmal thrombosis in the early postembolization period. Although postembolization mass effect on cranial nerves and other adjacent structures has been previously reported, we are unaware of reports involving the anterior
We herein report the first case of progressive perianeurysmal edema preceding the rupture of a small saccular aneurysm, without any intervention or intraluminal thrombosis. A 71-year-old woman was incidentally noted to have a cerebral aneurysm (5mm in diameter) at the lower basilar artery. Twelve
Two cases of giant left middle cerebral artery aneurysm presenting with rapidly progressing hemiparesis and aphasia are presented. In both, the computed tomographic scan showed recent intraaneurysmal thrombosis and massive edema and swelling of the cerebral hemisphere. There was no evidence of
The authors report the first case of vasogenic cerebral edema due to a cell-mediated hypersensitivity reaction to a nickel-containing aneurysm clip. The patient initially presented for elective clipping of a right middle cerebral artery aneurysm, and on long-term follow-up she demonstrated
A case of ruptured true posterior communicating artery aneurysm with neurogenic pulmonary edema is presented. A 31-year-old male suffered the sudden onset of unconsciousness with respiratory dysfunction and pinkish foamy sputum. Computed tomography demonstrated diffuse subarachnoid hemorrhage and
We report two rare cases of late-onset brain edema after craniotomy for clipping or coating of unruptured intracranial aneurysms, possibly due to an allergic reaction to topically applied fibrin glue or gelatin sponge used for arachnoid plasty to cover the opened sylvian cistern. Both patients were
A 16-year-old male adolescent presenting with acute retro-orbital pain underwent emergent internal carotid occlusion for a giant cavernous aneurysm. Three weeks later, the patient complained of headache and right hemiparesis, which suggested an acute stroke. CT and MR imaging revealed vasogenic
OBJECTIVE
Symptomatic local inflammation, aseptic meningitis, and hydrocephalus are reported in a group of patients treated with second generation/modified platinum coils. The purpose of this study was to define the frequency and determinants of magnetic resonance (MR) imaging findings of aneurysm
We describe a 48(correction of 44) year-old woman, who presents a non-cardiogenic pulmonary edema caused by non-ionic radiographic contrast medium. She suffered from subarachnoid hemorrhage due to dissecting aneurysm of right vertebral artery. Cerebral angiography followed by coil embolization for
BACKGROUND
Perianeurysmal edema and aneurysm wall enhancement are previously described phenomenon after coil embolization attributed to inflammatory reaction. We aimed to demonstrate the prevalence and natural course of these phenomena in unruptured aneurysms after endovascular treatment and to
