BACKGROUND: Computed tomographic angiography (CTA) has been shown to reliably detect aneurysms pre-operatively. The aim of this study was to compare the ability of post-operative CTA to detect aneurysmal remnants in connection with clip placement compared with digital subtraction angiography (DSA). Furthermore, special attention was paid to identifying factors influencing ...

The essential etiologic factors of intracranial berry aneurysm may be the hemodynamic stress on the arterial wall. Vascular remodeling triggered by abnormal hemodynamic stress on the blood vessels may play an important role in the formation, development and rupture of intracranial aneurysms. However, the specific causative mechanisms associated with this ...

Aneurysmal coronary artery disease is frequently encountered in clinical cardiology practice. Although more commonly associated with atherosclerosis, a variety of other acquired (eg, inflammatory, infectious, iatrogenic) or congenital causes have been identified. Recent research on the pathogenesis of coronary aneurysms has yielded interesting results. Advances in imaging have also provided ...

Recently neuroendoscopic third ventriculostomy has become a well-established procedure for the treatment of noncommunicating hydrocephalus. However, morphological changes of the third ventricular floor can make endoscopic fenestration technically difficult, and increase the risk of injury to the basilar artery and perforators. The risk is especially high in patients with basilar ...

Traumatic intracranial aneurysms are uncommon and represent fewer than 1% of all cerebral aneurysms. They may develop after blunt or penetrating head injuries and can present both diagnostic challenges and surgical difficulties. Because traumatic aneurysms are fragile and prone to rupture, early diagnosis with cerebral angiography and prompt treatment are ...

Abdominal aortic aneurysm is a common condition that may be lethal when it is unrecognized. Current guidelines suggest repair as the aneurysm diameter reaches 5.0 to 5.5 cm. Most aortic aneurysms are detected incidentally when imaging is done for other purposes or through screening programs. Ninety percent of these aneurysms ...

OBJECTIVE: Conventional cerebral angiography is the standard examination used to confirm aneurysm obliteration. Intraoperative indocyanine green (ICG) video angiography has recently been introduced as a valuable tool that is comparable to catheter intraoperative angiography. Intraoperative imaging evaluation is especially useful when complex aneurysm features are present, making direct clipping challenging. ...

OBJECTIVE: Blood blister-like aneurysms are small hemispherical bulges from the dorsomedial wall of the internal carotid artery that resemble berry aneurysms but differ in their clinical and surgical features. On the basis of our literature review, blister-like aneurysms have been reported to occur only at nonbranching sites of the dorsomedial ...

Aneurysms arising from the distal portion of superior cerebellar artery are infrequently seen. They are usually assumed to result from local arterial wall disruption like proximal supratentorial artery aneurysms. Depending on institutional facilities, these particular aneurysms can be treated either by a microsurgical procedure or interventional radiological technique. In general, ...

Fenestrations (segmental duplications) of the intracranial arteries are rare anomalies, felt to result from incomplete fusion of primitive embryologic vessels. They have been associated with aneurysms and other vascular lesions. The rate of fenestrations based on published angiographic series has been much lower than that at cadaveric series. The purpose ...

The authors report a rare case of an aneurysm arising at fenestrated anterior cerebral artery. The embryogenesis of this anatomical variation is discussed along with the review of relevant literature. Management of such lesions depends upon the location and morphology of the aneurysms and intracranial vascular anatomy. The authors discuss ...

Vascular manifestations of Behçet's disease include venous and arterial occlusions, arterial aneurysm and pseudo-aneurysm formation. The main problem of the surgical treatment of vascular lesions in Behçet's disease is the high incidence of complications such as recurrent aneurysms, thrombosis and fistulization to the adjacent organs. Here we present a case ...
