Director, Neurointerventional Radiology

In the early 1990s, the Department of Radiology at Montefiore established a dedicated Interventional Neuroradiology section of the Division of Neuroradiology to treat patients of all ages with vascular diseases of the central nervous system and spine, particularly aneurysms and stroke.

We currently offer the largest interventional pain management radiology program on the East Coast. Our stroke and neurology staff has expanded exponentially over the past few years. The division now includes five dedicated interventional neuroradiologists. 

Conditions and Procedures

Ongoing research is a crucial element of our mission to develop critical breakthroughs and treat pain, vascular diseases and spinal disorders. Our distinguished staff members have published papers on endovascular transvenous embolization of sinus pericranii, deep brain reversible encephalopathy, computer tomography guided sacroplasty, stroke prevention, back pain management, stenting for brain aneurysms, with various clinical, basic and translational studies in progress at all times.

A Comprehensive, Multidisciplinary Approach to Care

We offer treatment for the entire spectrum of neurovascular diseases:

  • Acute stroke
  • Brain aneurysm
  • Brain AVMs,
  • Carotid-cavernous fistula
  • Dural arteriorvenous fistula
  • Spinal arteriorvenous malformations
  • Spinal arteriorvenous fistulae AVFs
  • Cancer (brain, head, neck and spine)
  • Epistaxis Vein of galen malformations
  • Vasospasm

We also provide pain management care for oncologic discomfort from tumors, back pain due to degenerative disease, trauma, sympathetic dystrophies and post-operative back pain, which we treat with spinal stimulators.

Montefiore is the only facility conducting percutaneous spinal stimulators trials with intrathecal pumps; the procedure takes place in our state-of-the-art interventional suite. Other cutting-edge procedures we perform include: 


  • CT or fluoroscopy-guided Lumbar puncture, Lumbar drain placement, or Myelogram.
  • CT and fluoroscopic guided percutaneous biopsies and drainages.
  • CT guided epidural and perineural spine injections.
  • CT guided blood patches for headache management.
  • CT or fluoroscopy-guided bone marrow biopsy.
  • Percutaneous vertebroplasty, kyphoplasty, sacroplasty to reduce the compression or vertebral fractures often associated with osteoporosis.


  • Thrombolysis and thrombectomies (pharmacologic and mechanical) for stroke management.
  • Intracranial treatment of atherosclerotic disease with angioplasty and stenting.
  • Endovascular coil embolization/stenting of aneurysms.
  • Treatment of Vasospasm including pharmacology and/or angioplasty.
  • Treatment of Intracranial AVM or dural AVF with coils, glue, or other liquid agents.
  • Transarterial, transvenous and direct puncture embolization of congenital and acquired AVFs and congenital AVMs.
  • Transarterial embolizations of spinal AVMs and AVFs.
  • Wada testing in collaboration with the department of neurology.
  • Temporary and permanent balloon occlusion of intracranial and brachiocephalic vessels.

Head and Neck:

  • Extracranial Carotid angioplasty and stenting.
  • Tumor embolization and covered stenting for aggressive neck tumors.
  • CT-guided Biopsy of head and neck pathology.
