Saccular aneurysms of meningeal artery: case report.

Objective And Importance: A rare observation of double saccular aneurysms of the meningeal artery is presented.

Clinical Presentation: This 22-year-old man was referred to the Neurosurgical Institute with a suspicion of an aneurysm of the anterior communicating artery. Bilateral angiography of the carotid arteries was performed 1 week after the subarachnoid hemorrhage, but the aneurysms were not visualized.

Angioplasty of vasospasm: is it reasonable?

Clinical and radiographic examinations indicate preliminarily indications that transluminal angioplasty may be effective in overall management of the patient with vasospasm. Many questions remain, including: How does it work?; Are the effects persistent?; Is the arterial wall injured by the process? Recent studies in several patients who died after angioplasty allow us to provide some answers. Undilated spastic arteries show proliferation of both cellular and connective tissue elements.

Treatment of patients with intracranial arterial aneurysms in the haemorrhagic period.

Our research protocol was implemented in the treatment of 395 patients in the acute period following aneurysmal subarachnoid haemorrhage. Patients are classified as follows: Compensated (roughly Hunt and Hess I-II); Subcompensated (Hunt and Hess III); and Decompensated (Hunt and Hess IV-V). Only patients in the compensated state are deemed candidates for acute surgery.

Thrombosis of a giant aneurysm after extracranial-intracranial bypass.

A patient presenting with a giant, fusiform middle cerebral artery aneurysm underwent extracranial to intracranial bypass grafting before permanent occlusion of the aneurysm. The patient was to return 4 months later for endovascular treatment. Arteriography obtained before obliteration revealed complete aneurysmal thrombosis.

Coexistent hemangioblastoma and arteriovenous malformation of the cerebellum. Case report.

A case of cerebellar hemangioblastoma and coexistent arteriovenous malformation (AVM) is presented. Angiography displayed the AVM, but histological examination revealed a coexisting hemangioblastoma. Various theories concerning the etiology of this condition are discussed.
