Vascular Neurosurgery

Cerebrovascular surgery is among the most challenging of the disciplines in neurosurgery. Its stakes are high and the feld is complex and experiencing a high rate of evolution. Neurosurgeons who choose to face its challenges must constantly perfect their knowledge and skills to be equal to its formidable tasks. One of the best ways to stay current is to test oneself. You hold in your hands a most compelling instrument to achieve that aim. Tis volume by Dr. Hoz and his colleagues represents a study tool that covers the key content areas of vascular neurosurgery. Te student of neurosurgery, the resident, the fellow, and the younger neurosurgeon preparing for board exams or practice will be the most obvious benefciaries from this work. Te question and answer format is accessible, direct, and time efcient. I believe it is one of the most valuable forms of study. Te answers in this guide are detailed yet clearly are distillations of the most important information, from which the extraneous have been wisely excluded. One recalls the famous quote of Antoine de Saint-Exupéry that perfection is attained not when there is no longer more to add but when there is no longer anything to take away. Te reader would do well to read this well-chosen content even if he or she gets the answer correct, as there is much to be gained from its review. Even later stage neurosurgeons can beneft from the effort to go through it, as I have myself.

Navigated Transcranial Magnetic Stimulation in Neurosurgery

Mapping and monitoring of brain function is far from being new. It has always been in the focus of neurosurgeons, i.e., already in the days of Wilder Penfeld using awake surgery to map motor and sensory function (Penfeld and Boldrey 1937). The reason for this being quite obvious is to completely remove tumors or epileptogenic tissue without hurting the patient. To achieve this ideal goal has stimulated many neurosurgeons ever since, among them myself. In the early stages of my career in the late 1980s, I developed an interest in clinical neurophysiology, focusing on the rather new technique of motor evoked potentials (MEP) (Meyer and Zentner 1992; Barker et al. 1985). This technique triggered a development of monitoring and mapping of motor function in the asleep (anesthetized) patient. Several innovative groups paved the road for the integration of this technique into clinical routine, while simultaneously, awake craniotomy for language mapping and monitoring saw a renaissance (Penfeld and Boldrey 1937; Taniguchi et al. 1993; Cedzich et al. 1996; Deletis 1993). Thus, it became part of the neurosurgeons’ armamentarium even before studies showed that intraoperative MEP mapping and intraoperative monitoring (IOM) can actually prevent neurological damage (Sanai and Berger 2010; Duffau et al. 2005; De Witt Hamer et al. 2012). Today, IOM and intraoperative MEP mapping via DES are well-established techniques, which according to me are mandatory for the resection of highly eloquent tumors.

Tutorials in Endovascular Neurosurgery and Interventional Neuroradiology

From whence we come… What is the value of studying embryology when variant and anomalous vessels are so uncommon? Surely we always rely on a detailed analysis of each patient’s vascular anatomy to guide endovascular treatments. For me, anatomy is like a city street map. To be more precise, it is like the streets and roads of London, where I grew up. As a child I learnt to navigate those within walking distance of home and knew only main routes taken by car or bus to visit friends, shopping and other excursions. This familiarity of use fundamentally changed when I learnt to drive and was no longer a passive observer. Now, consider the role of chauffeur extended to showing visitors around my city. My priority changed, from learning shortcuts, good parking places and congestion avoidance (though all very useful to the city guide), to pointing out the sites and important historic places. We should learn the history of the routes we travel to deliver our therapy with the intimacy of the London cab driver and be prepared for the obscure address which few but they would know. In embryology we have a chance to marvel at the compressed evolution of foetal development. By learning about those processes, we are delighted when recognising throwbacks and anomalies, which, like historic sites, provide evidence of ‘from whence we come’.
