Objective—To determine outcome of and complications
associated with prophylactic percutaneous laser
disk ablation in dogs with thoracolumbar disk disease.
Procedure—Medical records of dogs with a history
of thoracolumbar disk disease in which the 7 intervertebral
disks from T10-11 through L3-4 were ablated
with a holmium-yttrium-aluminum-garnet laser inserted
through percutaneously placed needles were
reviewed. Complications and episodes of a recurrence
of neurologic signs (eg, paresis or paralysis)
were recorded. Owners were contacted by telephone
for follow-up information.
Results—Nine of 262 (3.4%) dogs for which followup
information was available had a recurrence of paresis
or paralysis. Follow-up time ranged from 1 to 85
months (mean, 15 months); signs recurred between
3 and 52 months (mean, 15.1 months) after laser disk
ablation. Acute complications occurred in 5 dogs and
included mild pneumothorax in 1 dog, an abscess at
a needle insertion site in 1 dog, and proprioceptive
deficits in 3 dogs, 1 of which required hemilaminectomy
within 1 week because of progression and
severity of neurologic signs. One dog developed
Conclusions and Clinical Relevance—Results suggest
that prophylactic percutaneous laser disk ablation
is associated with few complications and may
reduce the risk of recurrence of signs of intervertebral
disk disease in dogs. (J Am Vet Med Assoc 2003;222:
OBJECTIVE To determine incidence of and risk factors for major complications occurring in dogs within 30 days after cytoreductive surgery performed by a single pair of surgeons for treatment of suspected primary intracranial masses.
DESIGN Retrospective cohort study.
ANIMALS 160 client-owned dogs that underwent cytoreductive surgery for treatment of suspected primary intracranial masses between January 2009 and December 2015 at a veterinary teaching hospital.
PROCEDURES Medical records were retrospectively reviewed for complications occurring within 30 days after surgery. Data (eg, signalment, clinical signs, previous treatments, preoperative neurologic examination findings, neuroanatomical location, time from onset of clinical signs to surgery, surgical approach, and histopathologic diagnosis) were analyzed for associations with death and with development of major complications other than death.
RESULTS 21 (13.1%) dogs died (11 during hospitalization and 10 after discharge) and 30 (18.8%) developed major complications other than death during the first 30 days after surgery. Dogs with abnormal preoperative neurologic examination findings were more likely to develop complications or die. Dogs undergoing a suboccipital approach were more likely to die. The most common postoperative complications other than death were seizures (n = 18 [11.3%]), worsening of neurologic status (6 [3.8%]), and aspiration pneumonia (6 [3.8%]).
CONCLUSIONS AND CLINICAL RELEVANCE Results of the present study provided valuable information on predisposing factors, odds of major complications or death, and incidences of major complications or death in dogs during the first 30 days after undergoing cytoreductive surgery for treatment of suspected primary intracranial masses. Careful case selection may help improve outcomes and minimize complications.
