Historical Landmarks in the Management of Aneurysms and Arteriovenous Malformations of the Central Nervous System.

Objective: To describe the history of vascular and endovascular neurosurgery.

Methods: A literature research was conducted including historical events from 2000 bc to the twenty-first century ad, and a timetable was filled with information regarding the most representative historical landmarks regarding vascular and endovascular neurosurgery.

Results: Starting from approaches limited to the cervical carotid artery, vascular neurosurgery gained its way through the intracranial and finally endovascular space thanks to the introduction of both innovative and progressively less invasive procedures.

Immunohistochemical analysis of a ruptured basilar top aneurysm autopsied 22 years after embolization with Guglielmi detachable coils.

The authors report on the histologic and immunohistochemical analyses of a cerebral aneurysm embolized with platinum coils and with the longest observation period. A 58-year-old woman presenting with subarachnoid hemorrhage due to ruptured basilar top aneurysm was treated with Guglielmi detachable coils (GDC) 22 years ago. She was the 15th case since the GDC was introduced.

History of the genesis of detachable coils. A review.

The genesis of detachable coils and the background of this genesis are described in this article. To frame the beginning developmental stages of the discovery of detachable coils, the previous extravascular-intravascular and endovascular techniques are presented, as well as the development of the various delivery systems. The experimental studies, initial clinical application, and crucial moment of the conception of detachable coils are also reported.

Endovascular treatment of 306 anterior communicating artery aneurysms: overall, perioperative results.

Object: A series of 306 consecutive patients with an anterior communicating artery (ACoA) aneurysm is presented. The goal in this study was to report the results of endovascular treatment of ACoA aneurysms in these patients.

Methods: The aneurysms were managed with an endovascular approach in which detachable coils were used.

Analysis of the hemodynamic characteristics of brain arteriovenous malformations using electrical models: baseline settings, surgical extirpation, endovascular embolization, and surgical bypass.

Objective: The goal of this report is to analyze the hemodynamic characteristics of low- and high-flow arteriovenous malformations (AVM) using computerized electrical models.

Methods: Two electrical models of brain AVMs were created. These models consist of electrical resistors that simulate AVM vessels.

The Guglielmi detachable coil "crescent" in the endovascular treatment of peripheral brain aneurysms: technical case report.

Objective: Peripheral brain aneurysms arise from the distal segments of cerebral arteries. They can be treated by surgery or by an endovascular approach. We present our experience of endovascular treatment of peripheral brain aneurysms with a novel endovascular device, the Guglielmi detachable coil (GDC) "crescent.

Bypass combined with embolization via a venous graft in a patient with a giant aneurysm in the posterior communicating artery and bilateral idiopathic occlusion of the internal carotid artery in the neck.

The authors describe the case of a patient with a symptomatic giant aneurysm of the posterior communicating artery (PCoA) associated with bilateral idiopathic occlusion of the internal carotid artery (ICA). The presence of severe tortuosity of the vertebral arteries (VAs), both at their origin from the subclavian artery and at the level of the third segment, impeded navigation of the catheter for embolization of the aneurysm with Guglielmi detachable coils (GDCs). A direct surgical approach was considered to be a high-risk procedure because of the bilateral occlusion of the ICAs and the size of the aneurysm.
