Increase in Overall Survival (OS) of patients with high grade gliomas (HGG) at 1 year using IOUS1

    Use intraoperative ultrasound during surgery to:

  1. Assist in the identification of brain shift after pre-operative scans
  2. Determine extent of resection and assess for residual tumor

High and low grade gliomas, metastases, astrocytomas, abscess drainage, hematoma evacuations. Dual Live Compare with live image on left and previous scan on the right side.

Further resection of tumor remnants after intraoperative ultrasound1

    Use intraoperative ultrasound during surgery to:

  1. Avoid injury by identifying blood vessels near the pituitary gland
  2. Access hard-to-reach areas and use through cranial endoports with BK Medical’s smallest transducer
  3. Monitor resection progress and assess for residual tumor

Operative time with intraoperative ultrasound1

    Use intraoperative ultrasound during surgery to:

  1. Locate AVM nidus and identify feeding arteries with color Doppler2
  2. Assess for resection of AVMs2
  3. Identify associated hematoma3
  4. Visualize preoperative embolization (e.g. Onyx®)

Reduction in pediatric ventriculoperitoneal (VP) shunt revision rates with iUS1

    Use intraoperative ultrasound during surgery to:

  1. Guide safe, quick shunt placements
  2. Target the ventricle and confirm catheter placement in ventricle
  3. Reduce medical imaging hazards such as ionizing radiation
  4. Assess for brain shift and residual tumor

A COMPLETE NEUROSURGERY PORTFOLIO

Craniotomy Transducer N13C5
has outstanding image quality with a wide field of view and deep penetration, enabling an overview of the lesion and anatomy, and helping determine adequacy of lesion removal.
N11C5s Transducer (9063)*
has deep penetration and a small footprint to guide burr hole procedures with precision, including shunt placements and biopsies.
Hockey Stick Transducer X18L5s*
provides excellent resolution in the extreme near-field. It is ideal for use in spinal procedures and within cranial resection cavities as its flexible tip can be adjusted to 0°, 30°, 60°, and 90° positions.
Minimally Invasive Transducer N20P6*
is BK’s smallest transducer making it ideal for accessing hard-to-reach areas in endonasal skull base, cranial endoport, and spinal procedures.

Neurosurgery and Spine

 

ACTIVE IMAGING IS REAL-TIME VISUAL GUIDANCE FOR DECISION SUPPORT

The only real-time intraoperative imaging modality

Scan instantaneously and repeatedly wth iUS, while iCT and iMRI scans interrupt the surgical workflow1 and require a set scan time.

Minimum radiation hazards to the patient

Unlike iCT, intraoperative ultrasound does not involve ionizing radiation.2

Comparable gross tumor resection rates to iMRI

In a recent article, iUS has demonstrated gross total resection (GTR) for High Grade Gliomas (HGG) that is not statistically different from iMRI and 5-ALA.3
