Vertebro-basilar Ischaemia

Skull Base Approaches for Vertebro-Basilar Aneurysms

Microscopic anatomy of the human vertebro-basilar system.

Concerning the structure of connective-muscular components the authors studied the walls of the terminal segments of the vertebral arteries as well as the basilar artery, utilizing the following staining methods: Azan modified by Heidenheim, Weigert's resorcin-fuchsin, and Weigert modified by van Gieson. It was established that wall of the vertebro-basilar system exhibits a mixed structure, mus...

概要 1959年 より1963年 の5年 間 に,東 邦大学阿都 内科 で観察 した内頚 お よび椎 骨脳 底 動脈循環不 金 症45例 にっ き,臨 床症状の特 徴を統 計的 に観察す るとともに,そ の発生頻 度を検討 した.ま た,本 症 と本 態性 高血圧症,低 血圧症,正 常血圧 者お よび若年性起 立性 低血圧 の 患者群につ いて比較 し,本 症 の発生機序 につ い て検討 を加 えた.そ の結果,本 症 の大多数は既 往に高血圧 を有 し,発 作時 に血 圧 低 下をし たが,約70%は 起立性低 血圧 を伴なつ た高血圧症 であつ た.Mecholyl試 験 で は 変感神 経 緊 張低下 を示 す点で他群 と異なつ てお り,体 位変換 に よつて血 中norepinephrineが 増加 せず,安 静時 の 血中norepinephrineは 本態性高血圧症 ...

MR-based, subject-specific computational fluid dynamics modeling of the vertebro-basilar system

Introduction. Intimal hyperplasia (IH) is a common cause of coronary artery bypass graft failure, and previous studies have demonstrated a correlation between IH and hemodynamic factors (e.g., wall shear stress) and used this correlation to influence graft design [e.g., 1-4]. The vertebrobasilar system is one of the few locations in the human arterial tree where two major arteries (vertebral ar...

Variations in Diameters of Vertebro-basilar Tree in Patients with or with No Aneurysm

INTRODUCTION The morphological anatomy of the posterior circulation is very complex and variable. Aims of this research were to document the morphological anatomy of the posterior circulation along with variations in the Bosnian population, in patients with or without aneurysm. Measurements of the outer diameters of the vertebral artery, basilar artery and posterior cerebral artery were taken. ...
