Results
Twelve patients (mean age 60 yrs,
range : 17-79) with chronic chest pain underwent treatment as a cryoneurolysis during the period of January 2012 through June 2014.
In total,
thirty-two cryoneurolysis were performed.
Patients had two main causes for their pain: pleural metastasis or tumor infiltration of the gutter between rib and vertebra.
Mean pre-operative VAS was 6,6 out of 10 (range: 5-8) for worst pain in a 24-hour period.
The results in the time of follow-up are summerized in
Table 1.
Technical success was 100%. The number of cryoneurolysis was 3 to 5 levels with a median of 3 levels per patient.
The median duration of procedures was 120 minutes,
comprising installation time under the operative CT, disinfection rules,
anesthesia induction time (9 general anesthesia,
3 neuroleptanalgesia),
operative time,
and wake-up time.
No major complication occurred (as pneumothorax,
local infection,
epidural hematoma because of gas injection in the epidural space,
intercostal arteries damage,
spinal cord injuries).
Minor complications occurred (n=2) as subcutaneous hematoma spontaneously resolute in few days.
The median hospital stay for cryoneurolysis was 2 days (1-4 days),
and long stays were because of general state and not relevant to the procedure.
Median follow-up was 5 months (max 15.5 months,
min 10 days).
This short interval of time is explained by the poor performance status of our patients,
who are in palliative care.
