Dr. Siviero Agazzi, MD
Italian born and Swiss trained, I obtained the Swiss Board Certification in Neurological Surgery in 2002. I then pursued advanced training in complex cranial surgery by completing a fellowship in Skull Base and Cerebrovascular Surgery. In 2005 I joined the faculty of the University of South Florida Department of Neurosurgery. Since then I have dedicated my practice to complex brain surgery and have gained a significant experience in the treatment of tumors (acoustic neuromas, meninigiomas, gliomas), vascular diseases (aneurysms and arteriovenous malformations), trigeminal neuralgia and hemifacial spasm. My expertise has been solicited several times by other neurosurgical teams for complex cranial procedures both in adults and children. At the national level, I have been recognized as an expert in complex cranial surgery. I am married, have 2 children and am fluent in 5 languages

Very bad bedside manor. Rude!!
in New Port Richey, FL |
Dr. Agazzi treated my 19 year old son who was admitted to TGH with Bleeding in the Brain. After 3 days in the NICU, Dr. Agazzi diagnosed him w/(Bleeding) Brainstem Cavernoma. Although controversial, Dr Agazzi recommended surgery to resect the Cavernoma. This surgery required a highly skilled and specialized Neurosurgeon due to location in the brain & high risk of complete & permanent paralysis (along with other risks). Dr. Agazzi conducted the 7-8 hour surgery & my son will have a full recovery!

Went to him for hemifacial spasm advice. He took one look at my MRI and said I had MS. No one else saw this on my MRI. Turned out I do have both, but thanks to him I am getting treatment. I wish he could be my neuroligst!
in Hudson, FL |
Dr. Agazzi has performed 2 brain surgeries to remove metastatic tumors related to lung cancer. The first was in the area of speech, language processing, etc. and the second was very close to the motor skills area. Dr. Agazzi did a tremendous job on both surgeries!! His skill and expertise prevented any major affects on both gross and fine motor skills. He explained the procedure and potential side effects & was quick to report to the family following surgery. I HIGHLY recommend him!!

I suffered a stroke and aneurysm in December of 2014, luckily for me Dr. Agazzi was at Tampa General Hospital that morning. I credit Dr. Agazzi with extending my life to share with my family and to the TGH staff for excellent care and rehabbing, I thank them for improving my quality of life physically. Without a doubt I would refer Dr. Agazzi to someone in my prior situation. Thank You Dr. Agazzi, Thank you TGH staff !
