Dr. Nestor Gonzalez is Assistant Professor in Neurosurgery and Interventional Neuroradiology who has a unique training, having completed two separate and
distinct residency training programs in both Radiology and Neurosurgery as well
as a Fellowship in Interventional Neuroradiology.
Since his arrival to the Interventional Neuroradiology Division at
UCLA in 1999, he has participated in numerous research projects where his
contributions have been key for the development of the research plans, analysis
of data, and publication of the research results in prestigious national and
international medical journals and books. He has been active part of the
development of the generation of bioactive coils for the treatment of
intracranial aneurysms, which results have been object of several publications.
He directly participated in the development and analysis of the animal studies
that lead to the FDA approval of these coils, which have opened a new spectrum
of possibilities incorporating bioactive components for the treatment of
aneurysms.
He participated in the development of the "Merci" device, initially known as
"Concentric Retrieval" device, which is the first mechanical device approved in
the US for the endovascular treatment of ischemic stroke. He also participated
in the analysis and publication of the animal studies for the long-term
evaluation of a recently approved embolic material (Onix, previously known as
Embolyx) and the initial clinical experience using this material for head and
neck vascular lesions.
In addition to this research Dr. Gonzalez has been actively involved in
clinical research, leading several projects in both the Endovascular and
Neurosurgery Divisions at UCLA. He has analyzed and published one of the largest
series of unruptured intracranial aneurysms, analysis that has emphasized the
importance of some anatomical characteristics of these lesions. He is currently
working in a detail analysis of the impact of numerous geometric features that
may alter the efficiency of endovascular treatment of aneurysms and that would
play a fundamental role in the decision algorithm of treatment for these
lesions. Preliminary results of this analysis have been presented in National
Cerebrovascular meetings.
He also has several publications in neurocritical care for patients with
cerebrovascular disease, field in which he has lead the investigation of a
mathematical model developed by him that allows to predict vasospasm of the
cerebral arteries in patients with aneurismal subarachnoid hemorrhage combining
clinical factors of each patient with transcranial Doppler measures and cerebral
blood flow measures. The results of the first part of this research have been
accepted for publication in the November 2007 issue of the Journal of
Neurosurgery, and they have been presented in several Neurosurgical and
Cerebrovascular meetings. He is currently developing a prospective phase for
this project that includes subarachnoid blood volume analysis and cerebral
perfusion studies to the previously included factors to improve the accuracy of
the predictive model. Given his interest and contributions in neurocrital care,
he has been invited to write book chapters in international books in the
critical care of patients with cerebrovascular injuries for the Oxford
University Press and the editorial house Mason from Spain.
Dr. Gonzalez has additional interests in history of medicine and medical
ethics, fields that he cultivated in his native country. He published numerous
articles and ethical discussions, as well as papers and reviews in medical
history. He was designated editor of the "Heraldo Medico" journal devoted to
legal and ethical issues published by the Colombian Medical Federation and for
several years work as Assistant Professor of History of Medicine and Medical
Ethics in his medical school at the Rosario University, one of the most
traditional and prestigious schools of Medicine in Latin-America, where he was
honored with the equivalent of the Summa Cum Laude, Collegialium Majoris, and a
medal for the highest grades ever in the history of the medical school.
