Vascular and Endovascular Neurosurgery

Hackensack University Medical Center is on the cutting edge of the treatment of intracranial vascular disorders, including brain aneurysms, arteriovenous malformations (AVM's) and stroke. 


Our Cutting-Edge Treatments
The Heart & Vascular Hospital at HackensackUMC offers the latest technology for minimally-invasive treatments of intracranial vascular disorders, including:

  • Coil embolizations
  • Stent assisted coil embolizations
  • Pipeline embolizations
  • Gamma Knife Radiosurgery

A wide array of multi-modality treatment options for the treatment of intracranial arteriovenous malformations, including:

  • Embolizations with nBCA or Onyx
  • Gamma Knife Radiosurgery
  • Microsurgical resection. 

A full array of neurointerventional procedures, including:

  • Cerebral and spinal angiograms
  • Acute stroke interventions
  • Angiography and embolization for brain and spinal arteriovenous malformations
  • Dural arteriovenous fistulas
  • Intracranial angioplasty and stenting
  • Carotid artery stenting with distal protection
  • Embolization for Carotid-Cavernous Fistulas
  • Pre-operative embolization of brain and spinal tumors
  • Pre-operative embolization of head and neck tumors
  • Embolization for refractory epistaxis (recurrent, severe nosebleeds)
  • Microsurgical Procedures
    • Clipping of brain aneurysms
    • Resection of AVM's
    • Resection of cavernomas of the brain or spine
    • Ligation of cranial or spinal arteriovenous fistulas
    • ECIC (Extra-Cranial to Intracranial) bypass for Moya-Moya, complex aneurysms, and select complex tumors
    • EDAS (Encephaloduroarteriosynangiosis) for Moya-Moya


For patients not eligible for minimally invasive techniques, traditional open microsurgery is offered with some of the best outcomes in the country. The procedures are often supplemented by newer technologies such as fluorescein angiography and/or intraoperative angiography.  With the recent addition of Dr. Reza Karimi to the staff at HackensackUMC, we have also added an intracranial bypass program for those rare patients requiring revascularization of the brain for Moya-Moya disease, complex brain aneurysms or some tumors. 

The Heart & Vascular Hospital at HackensackUMC has become the highest volume brain aneurysm center in Bergen County, under the leadership of Dr. Daniel Walzman. 


The Comprehensive Stroke Center at HackensackUMC
The Comprehensive Stroke Center at HackensackUMC offers the newest and latest technologies for the endovascular treatment of acute ischemic stroke. The Center currently offers the use of the Penumbra Aspiration System as well as the Solitaire and Trevo Stent retriever devices.  Furthermore, under Dr. Walzman’s leadership, the Comprehensive Stroke Center has some of the most successful revascularization rates in the world for thrombo-embolectomies in the treatment of acute ischemic stroke.


Vascular and Endovascular Neurosurgery Leadership
Dr.  Daniel Walzman is the chief of Vascular and Endovascular Neurosurgery at HackensackUMC.  He first came to HackensackUMC in 2005, and was one the first neurosurgeons in the state of  New Jersey to have dual training  in both endovascular  neurosurgery as well as traditional open micro-neurosurgery  for the treatment of vascular disorders of the brain.  Dr. Walzman was one of the first few neurosurgeons in the state to offer minimally-invasive embolizations for the treatment of brain aneurysms, and was the first physician in Bergen County to perform thrombo-embolectomies utilizing the MERCI (Mechanical Embolus Retrieval in Cerebral Ischemia) retriever for the treatment of acute ischemic stroke.  Dr Walzman was also the first physician in the greater New York metro area to utilize the Trevo Pro stent retriever device for the treatment of acute ischemic stroke

Dr. Walzman has been selected as a primary investigator for the Therapy Trial, a multi-center trial comparing IV-TPA alone to IV-TPA followed by thrombo-embolectomy utilizing the Penumbra Clot Aspiration System.  Furthermore, Dr Walzman is also a primary investigator in an additional clinical trial to investigate the safety and utility of the Penumbra 3D Separator Device for use in thrombo-embolectomies for the treatment of acute ischemic stroke.
