» Conditions & Treatments » Neuroscience » Neurointerventional Surgery

Year-round and 24/7, the Queen’s Neurointerventional Surgery Team at the Neuroscience Institute (NSI) provides comprehensive, minimally invasive treatments for a wide range of conditions of the brain, spine, head, and neck. Treatments include extracting blood clots from blood vessels in stroke patients; stenting narrow blood vessels to increase blood flow to the brain; and shutting down aneurysms, arteriovenous malformations, fistulas, and tumors of the brain and spine.

Our Services

Using state-of-the-art imaging and the latest minimally invasive technologies and techniques, we are able to treat the most complex cerebral vascular diseases including:

  • Brain aneurysms
  • Cerebral Venous Congestion and Idiopathic Intracranial Hypertension
  • Cerebrospinal fluid (CSF) leaks
  • Stroke – emergent and preventative therapies
  • Head and neck emergencies such as epistaxis, tumor bleeds, etc
  • WADA testing for epilepsy surgery patients
  • Bone augmentation for spinal and sacral fractures
  • Pulsatile tinnitus
  • Arteriovenous malformations / fistulas of the brain and spine
  • Vascular brain tumors
  • Angioplasty and stenting of the carotid and intracranial blood vessels
  • Traumatic injury to blood vessels of brain, head and neck
  • Subdural hematoma embolization
  • Ablation and embolization for spinal column tumors
  • Vascular "brain fog"

Ask a Specialist: Brain Aneurysms with Dr. Samuel Tsappidi

Brain aneurysms can be a scary thing to deal with, especially because they can happen without warning. In this episode of Ask a Specialist, we talk about what you need to know with Dr. Samuel Tsappidi, Neurointerventional Surgeon at The Queen’s Medical Center.

Education

The Neuroscience Institute is pleased to announce the start of a Neurointerventional Surgery Fellowship in 2024 in collaboration with the John A. Burns School of Medicine (JABSOM) at the University of Hawai‘i at Manoa. This exciting opportunity is staffed with providers from neurology, neurosurgery, and neuroradiology. The training experiences encompass the entire spectrum of neurovascular disorders including hemorrhagic, ischemic, neoplastic, and venous disorders of the brain, spine, head and neck.

Clinical Trials

Research provides the foundation for our advanced neurological treatments, as well as the education of physicians and staff. We partner with national research hospitals and institutions to expand the quality of care we provide patients.
