Kenneth Tran, MD
Clinical Assistant Professor, Surgery - Vascular Surgery
BioDr. Tran is a vascular surgeon in the Vascular and Endovascular Surgery Division at Stanford Health Care. He is also a clinical assistant professor in the Department of Surgery, Division of Vascular Surgery at Stanford University School of Medicine.
Dr. Tran’s clinical expertise includes the entire spectrum of vascular surgery, including minimally invasive strategies for aortic aneurysm repair and multiple methods of managing peripheral vascular disease. He also specializes in treating cerebrovascular disease (problems with blood flow in the brain) using carotid angioplasty and stenting, transcarotid artery revascularization, and conventional carotid surgery. In addition, Dr. Tran offers comprehensive dialysis access management and treats venous reflux (when leg veins fail to return blood to the heart).
Dr. Tran has a special interest in minimally invasive techniques for repairing complex aortic conditions using custom stents placed inside blood vessels (endografts). He has expertise in designing, fabricating, and implanting physician-modified endografts tailor-made to each patient’s unique aortic anatomy. This technique expands the ability to offer minimally invasive repair to more patients.
Dr. Tran’s research efforts focus on utilizing novel computational approaches to better understand and optimize blood flow patterns after complex aortic repair. This work has helped improve the understanding of how different types of aneurysm repair perform long term. Dr. Tran hopes to use these research findings to improve clinical outcomes for patients with aortic aneurysmal disease.
Dr. Tran has published his work in numerous prestigious peer-reviewed journals, including the Journal of Vascular Surgery, JAMA Surgery, and the European Journal of Vascular and Endovascular Surgery. He has presented at the podium at numerous national and international conferences.
Dr. Tran has received multiple research awards, including the Vascular and Endovascular Surgery Society’s Medtronic Resident Research Award and Best Resident Presentation at the Swiss Society for Vascular Diseases. In addition, he received the Young Researcher Prize at the European Symposium on Vascular Biomaterials for his research related to complex aortic repair hemodynamics (blood flow). Dr. Tran also coauthored a chapter in the book Complications in Endovascular Surgery. -

Andrea Traynor
Clinical Professor, Anesthesiology, Perioperative and Pain Medicine
BioI completed my training at Stanford University with an Anesthesiology residency in 2003 and Obstetrical Anesthesia fellowship in 2004. I worked in a general private practice for two years at a community hospital in Colorado and was involved in creating protocols for OB related concerns such as non-obstetric surgery during pregnancy and skin to skin contact in the OR during cesarean delivery. I then returned to academic practice and worked for eight years at the University of Colorado and the Colorado Institute for Maternal and Fetal Health. I have collaborated extensively with the Stanford Anesthesia Informatics and Media Lab to create innovative educational tools. These include a major anesthesiology textbook, the Manual of Clinical Anesthesiology, and a comprehensive online learning program for anesthesiology residents called Learnly. I've been the OB anesthesia fellowship director at both the University of Colorado and Stanford University. I truly love guiding fellows from interested residents to consultants in OB anesthesia. My research interests include medical education and topics related to the Obstetrical Anesthesiology workforce.
