POST NEVA VS
Narrowing improvement after NeVa VS deployment

PRESENTATION
- 50+ year-old male patient
- Treated Day 6 post-SAH on R-MCA segment vasospasm

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.”
PRE NEVA VS
Left-MCA has significant narrowing

POST NEVA VS
Left-MCA restored to near-normal size

PRESENTATION
- 26-year-old female patient
- Treated Day 6 post-SAH
INTERVENTION
- NeVa VS deployed three times to different vessels, three minutes each time
OUTCOME
- Neurological improvement
- 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

POST NEVA VS
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
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
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
Day 8, moderate vasospasm observed in the Right-M1
INTERVENTION
The case was performed under general anesthesia
Headway 27 microcatheter used to deploy NeVa VS
OUTCOME
Significant improvement of vasospasm observed on radiographic images
HIGHEST MCA MV: 79, Previously 272

SEVERE LEFT ACA AND MCA SPASM TREATED WITH NEVA VS
Dr Arthur Grigorian, MD, Wellstar North Fulton Medical Center. Roswell, Georgia
“Another successful vasospasm resolution with the NeVa VS. The patient continues improvement on TCD, her neuro-exam is stable, and so far, no further endovascular treatment needed…”
PRE NEVA VS
Severe left ACA- A1/A2 and left MCA-M1 spasm

POST NEVA VS
Vasospasmed branches restored to normal size

PRESENTATION
- 46-year-old female patient treated Day 8 post-SAH
INTERVENTION
5000 units of Heparin given prior to NeVa VS deployment
NeVa VS deployed twice in the ACA & once in the MCA
ACA: deployed, re-sheathed, re-deployed: total 5 min. deployment time
MCA: deployed, re-sheathed: total 2 min. deployment time
