Epidemiological Features of Nontraumatic Spontaneous Subarachnoid Hemorrhage in China: A Nationwide Hospital-based Multicenter Study.

Background: Nontraumatic spontaneous subarachnoid hemorrhage (SAH) is associated with a high mortality. This study was conducted to investigate the epidemiological features of nontraumatic spontaneous SAH in China.

Methods: From January 2006 to December 2008, the clinical data of patients with nontraumatic SAH from 32 major neurosurgical centers of China were evaluated.

Treatment strategies for complex internal carotid artery (ICA) aneurysms: direct ICA sacrifice or combined with extracranial-to-intracranial bypass.

Objective: Direct surgery for complex internal carotid artery (ICA) aneurysms can be difficult. In certain situations, sacrificing the parent artery is a unique way to obliterate the aneurysm and extracranial-to-intracranial (EC-IC) bypass is indispensable to prevent postoperative cerebral ischemia. This article discusses the indications for direct ICA occlusion, and the strategies, techniques, and outcomes in a series of patients treated for complex ICA aneurysms in a single institution.

Comparative study of covered stent with coil embolization in the treatment of cranial internal carotid artery aneurysm: a nonrandomized prospective trial.

To evaluate whether Willis covered stent implantation yielded angiographic and clinical results were better than those with coil embolization. Eighty-nine patients with cranial internal carotid artery (CICA) aneurysms were treated nonrandomly with covered stents (n = 43, group A) or coil embolization (n = 46, group B). Data on the technical success, procedure time, initial and final angiographic results, and final clinical outcomes were collected and analyzed at >6 months post-procedure.
