LEFT MCA SEGMENT VASOSPASM WITH SIGNIFICANT NARROWING

Dr. Reza J. Karimi, MD, FAANS, FACS, Hackensack University Medical Center, Hackensack, New Jersey

“The NeVa VS device was easily deployed in the target blood vessels and was remarkably effective in restoring spastic arteries to near normal size. The procedure was straightforward, efficient and ultimately the patient made a full recovery.”

Left-MCA restored to near-normal size

PRESENTATION
  • 26-year-old female patient
  • Treated Day 6 post-SAH

  • No further endovascular treatment needed

LEFT MCA VASOSPASM IMPROVED IN TWO DEPLOYMENTS

Dr Georgianne Snowden, MD, FACR, Integris Health Baptist Med. Center, Oklahoma City, Oklahoma

“I love having this new, very effective tool in our armamentarium for the battle against symptomatic vasospasm!”

PRE NEVA VS

Left MCA size:
1.02 mm

Left MCA size nearly doubled to: 2.02 mm

PRESENTATION
  • 57-year-old female

  • Treated Day 5 for post-SAH from ruptured basilar tip aneurysm treated by emergent stent coiling

  • Patient became more somnolent prior to the NeVa VS procedure. Transcranial dopplers were non-diagnostic

 

INTERVENTION
  • NeVa VS deployed two times in the MCA, for five minutes each time

 

OUTCOME
  • No further endovascular treatment needed

RIGHT MCA AND ACA TREATED WITH NEVA VS

Dr Arthur Grigorian, MD, Wellstar North Fulton Medical Center. Roswell, Georgia

“We observed excellent results with NeVa VS, with a marked improvement in mean transit time immediately after treatment, and the effect remained persistent.”

PRE NEVA VS

Significant narrowing of both MCA and ACA branches

POST NEVA VS

Vasospasmed branches restored to normal size

PRESENTATION
  • 23-year-old female patient treated Day 18 post-SAH
INTERVENTION
  • Heparin given prior to NeVa VS deployment
  • NeVa VS deployed once in the MCA and twice in the ACA for 2 minutes at each deployment
  • 5 mg Verapamil infused after NeVa VS
OUTCOME
  • Immediate and sustained improvement in MTT
  • No recurrence of spasm
  • No further endovascular treatment needed

MODERATE-SEVERE BASILAR ARTERY VASOSPASM RESOLVED

Dr Ryan M Hebert, Yale School of Medicine, New Haven, Connecticut

”We were able to successfully treat this patient’s vasospasm with NeVa VS under conscious sedation. A big win for the patient and team.”

PRE NEVA VS

Moderate-Severe Basilar Artery spasm, Soustiel Ratio 4.0

POST NEVA VS

Significant improvement, Soustiel Ratio improved to 2.6

DEPLOYMENT

NeVa VS deployed in the
Basilar Artery

PRESENTATION
  • Ruptured V4 Pica aneurysm was coiled
  • Day 4 post-rupture, moderate-severe basilar vasospasm was observed

 

INTERVENTION
  • The case was done under moderate sedation

  • The lesion was accessed with a 5 Fr guide and a .021” micro-catheter

 

OUTCOME
  • Soustiel Ratio improved from 4.0 before the intervention to 2.6 after NeVa VS deployment

SEVERE BASILAR VASOSPASM IN A 22 YO PATIENT

Dr Ameer Hassan, MD, Valley Baptist Neuroscience Institute, Harlingen, Texas

“Having NeVa VS on our shelf for severe vasospasm post SAH has proven to be a valuable tool for some of the sickest patients we see.”

PRE NEVA VS

Basilar segment
vasospasm

POST NEVA VS

Narrowing improvement after NeVa VS deployment

PRESENTATION
  • 22-year-old who initially presented with Hunt Hess 2, Fisher grade 3 SAH

 

INTERVENTION
  • NeVa VS 4.0 x 22 deployed via phenom 27 microcatheter for 10 minutes, then re-sheathed

  • 10mg of verapamil infused simultaneously via microcatheter

 

OUTCOME
  • Almost 300 % improvement in vessel diameter

MODERATE MIDDLE CEREBRAL ARTERY VASOSPASM RESOLVED

Dr Charles Matouk, Yale School of Medicine, New Haven, Connecticut

“Pretty nice response with NeVa VS from .8 to 1.25mm on a high grade SAH patient”

PRE NEVA VS

PRE NEVA VS

PRESENTATION
  • Ruptured 4mm Right anterior temporal aneurysm coiled
